Evaluation of Statin Indication and Dose Intensification Among Type 2 Diabetic Patients at a Tertiary Hospital

Background

Diabetes mellitus (DM) increases cardiovascular disease (CVD) incidence and mortality. While guidelines endorse statin use in type 2 DM (T2DM) to mitigate cardiovascular risks and mortality, challenges like statin initiation and prompt treatment adjustments affect patient outcomes. This study aimed to assess the appropriateness of indications for and dose intensification of statin therapy among T2DM patients at Tikur Anbessa Specialized Hospital (TASH).

Methodology

A hospital-based cross-sectional study was conducted from April 1 to June 30 2020. In total, 405 T2DM patients were selected using a systematic random sampling technique. The data were analyzed using SPSS version 26.0. An adjusted odds ratio (OR) was used and a 95% confidence interval (CI) and p-values of <0.05 were utilized to determine statistical significance.

Results

Of the total 405 participants, 346 (85.4%) started taking statins for primary or secondary prevention purposes. Indication for statin use was appropriate in 96.2% patients, while for 216 (62.4%) patients their doses were appropriately intensified. Predictors of the inappropriateness of statin use were an atherosclerotic cardiovascular disease (ASCVD) score of ≥7.5% (AOR=0.28; 95% CI: 0.102-0.738, p=0.01), the presence of dyslipidemia (AOR=4.48; 95% CI: 1.85-10.84; p=0.001), initiation of aspirin therapy (AOR=3.7; 95% CI: 1.522-9.144; p=0.004), and an LDL-cholesterol level of 70-189 mg/dL (AOR=0.124; 95% CI: 0.042-0.365; p=0.001). DM duration of ≥10 years (AOR=2.51; 95% CI: 1.35-4.66, p=0.004), male gender (AOR=2.04; 95% CI: 1.16-3.58, p=0.013), age ≥65 years (AOR=2.15; 95% CI: 1.23-3.75, p=0.007) and uncontrolled blood pressure (AOR=2.09; 95% CI: 1.07-4.08, p=0.031) were associated with inappropriate statin intensification.

Conclusion

The study found that indication of statins was optimal and about two-thirds of patients had their doses appropriately intensified. Monitoring is needed to avoid inappropriate intensification of statin therapy, particularly in patients with longer diabetes duration, those of male gender and advanced age, and those with uncontrolled blood pressure.

The Effect of Statin Therapy on Serum Uric Acid Levels: A Systematic Review and Meta-analysis

BACKGROUND

Elevated concentrations of serum uric acid (SUA) are associated with several conditions, including cardiovascular disease. The present study aimed to estimate the impact of statin therapy on SUA levels through a systematic review and meta-analysis of clinical trials.

METHODS

PubMed, Embase, Web of Science, and Scopus were searched on January 14, 2022, to identify eligible clinical trials. The intervention group received statins as monotherapy or in combination with other drugs, and the control group received non-statins or placebo. Studies reporting SUA levels before and after treatment were selected for further analysis. Finally, the data were pooled, and the mean changes in SUA, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides were reported.

RESULTS

Out of 1269 identified studies, 23 were included in the review. A total of 3928 participants received statin therapy, and 1294 were included in control groups. We found a significant reduction in SUA levels following statin therapy (mean difference (MD) = -26.67 μmol/L with 95% confidence interval (CI) [-44.75, -8.60] (P =0.004)). Atorvastatin (MD = -37.93 μmol/L [-67.71, -8.15]; P < 0.0001), pravastatin (MD = -12.64 μmol/L [-18.64, -6.65]; P < 0.0001), and simvastatin (MD = -5.95 μmol/L [-6.14, -5.80]; P < 0.0001), but not rosuvastatin, were significantly associated with a reduction in SUA levels. An analysis comparing different types of statins showed that pravastatin 20-40 mg/day could significantly reduce SUA when compared to simvastatin 10-20 mg/day (-21.86 μmol/L [-36.33,-7.39]; P =0.003).

CONCLUSION

Statins were significantly associated with a decrease in SUA levels, particularly atorvastatin, which was found to be most effective in lowering SUA. Atorvastatin may be the most appropriate cholesterol-lowering agent for patients with or at risk of hyperuricemia.

Effect of ABCA1-R219K Polymorphism in Serum Lipid Parameters in Patients under Statin Therapy Visiting Tertiary Cardiac Center of Nepal

Introduction  ATP-binding cassette transporter A1 (ABCA1) encoded by ABCA1 gene is one of the important protein involved in lipid metabolism. The effect of statin therapy on dyslipidemia varies among individuals and it may be due to different genetic polymorphism. The R219K polymorphism of ABCA1 gene is found to have a significant role in the response of statin. Objective  This study was designed to evaluate the effect of R219K polymorphism in lipid-lowering action of statin in patients with dyslipidemia. Material and Methods  This study was conducted in 88 patients. Blood samples were taken from patients before and at the end of 3 months of statin use and were analyzed for lipid profile. Whole blood was analyzed for R219K Polymorphism using polymerase chain reaction-restriction fragment length polymorphism. Results  R219K polymorphism was associated with significant percentage reduction of serum triglyceride/high-density lipoprotein (TG/HDL) ratio and total cholesterol/high-density lipoprotein (TC/HDL) ratio in atorvastatin users. However, there was no significant association of polymorphism with change in serum TC, HDL-C, LDL-C, TG, and very low-density lipoprotein (VLDL). Among KK genotype individuals, value of TG, VLDL, TG/HDL, and TC/HDL were significantly lower than in RR genotypes. Also, TG/HDL and TC/HDL were significantly lower in RK genotype than in RR. Treatment of dyslipidemia with statin was found to be comparatively better in patients having the genotypes KK and RK. Conclusion  Our study demonstrated association of R219K polymorphism with the significant reduction of TG/HDL and TC/HDL and particularly the KK genotype was associated with significant improvement of lipid parameters following atorvastatin treatment.

The Impact of Statin Therapy on Cardiovascular Outcomes in Patients With Diabetes: A Systematic Review

Cardiovascular disease (CVD) is the primary cause of death all over the world, especially due to myocardial ischemia caused by atherosclerosis that blocks cardiac arteries and leads to arrhythmia and other cardiac diseases. Meanwhile, diabetes mellitus (DM) and elevated cholesterol level are the risk factors for cardiovascular (CV) disease. This noncommunicable disease has become a main concern for us as cardiovascular disease develops in a slow manner without any symptoms in the early stage. Early prevention and intervention have a major impact on improving the outcome of cardiovascular health in diabetic patients. Controlling cholesterol level by administering statin has shown some beneficial impacts in reducing the risk of cardiovascular disease in patients with DM. This study used a systematic literature review (SLR) approach to give an overview of the current literature and to analyze the effects of statin therapy on cardiovascular outcomes in patients with DM. The literature search was conducted in PubMed and Google Scholar databases. The total number of articles included in the present review is six, obtained from reputable journals published between 2013 and 2023, and we only focused on reviewing six articles for in-depth analysis. The evidence we collected showed a positive outcome in terms of cardiovascular health in persons with DM after statin therapy. However, there are several risk factors that interfere with the effectiveness of statin in diabetic patients.

Gaps in Guideline-Based Lipid-Lowering Therapy for Secondary Prevention in the United States: A Retrospective Cohort Study of 322 153 Patients

BACKGROUND

Many patients with atherosclerotic cardiovascular disease (ASCVD) are not on guideline-recommended statin therapy. We evaluated utilization of statins and other lipid-lowering therapy (LLT), and changes in low-density lipoprotein cholesterol (LDL-C), among patients with ASCVD over a 1-year period.

METHODS

LLT and LDL-C levels at the first outpatient visit (January 1, 2017-December 31, 2018) and 1-year follow-up were evaluated using data from Cerner Real-World Data, an electronic health record-derived data set from 92 US health systems. Logistic regression was used to evaluate factors associated with high-intensity statin use.

RESULTS

We identified 322 153 patients with ASCVD (median age 69 years, 58.8% men, 81.8% White). Overall, 76.1% of patients were on statins, with only 39.4% on high-intensity statins. Men were more likely to receive high-intensity statins than women (multivariable-adjusted odds ratio, 1.34 [95% CI, 1.30-1.38]). Increasing age was associated with lower odds of statin use (odds ratio, 0.79 per 5-year increase at 60 years [95% CI, 0.78-0.81]). Patients with peripheral artery disease (odds ratio, 0.40 [95% CI, 0.37-0.42]) and cerebrovascular disease (odds ratio, 0.75 [95% CI, 0.70-0.80]) had lower odds of using high-intensity statins than those with coronary artery disease. At baseline, most patients (61.3%) had elevated LDL-C (≥70 mg/dL), including 59.8% of those on low/moderate-intensity statins and 76.1% on no statin; only 45.3% achieved an LDL-C <70 mg/dL at 1 year. Nonstatin LLT use was low (ezetimibe, 4.4%; proprotein convertase subtilisin/kexin type 9 inhibitors, 0.7%). Among patients on no statin or low/moderate-intensity statin at baseline, 14.8% and 13.4%, respectively, were on high-intensity statins at 1 year.

CONCLUSIONS

Among patients with ASCVD in routine care, high-intensity statins are underutilized, and uptitration and use of nonstatin therapy are uncommon. Women, older adults, and individuals with noncardiac ASCVD are particularly undertreated. Concerted efforts are needed to address therapeutic inertia for lipid management in patients with ASCVD.

Relationship of Missed Statin Therapy and 10-Year Atherosclerotic Cardiovascular Disease Risk Score to Retear Rate After Arthroscopic Rotator Cuff Repair

BACKGROUND

There is no practical consensus on managing cholesterol in patients with rotator cuff repair despite hyperlipidemia and statin therapy being well-known factors in rotator cuff healing. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk score is a commonly used guideline to determine statin administration for hyperlipidemia.

PURPOSE

To identify the relationship between retear and preoperative factors, including 10-year ASCVD risk score and statin administration status, and to compare clinical outcomes and retear rates between patients who are taking and not taking statins.

STUDY DESIGN

Case-control study; Level of evidence, 3.

METHODS

This study enrolled 182 patients with a symptomatic full-thickness rotator cuff tear who underwent arthroscopic repair. Serum lipid profile, 10-year ASCVD risk score, statin eligibility, and statin administration status were assessed. Patients were categorized into 2 groups based on magnetic resonance imaging to evaluate cuff integrity at postoperative 6 months: a healed group and a retear group. Radiographic and intraoperative factors related to retear were analyzed. Multiple regression analysis was performed to evaluate factors related to rotator cuff retear. For the subgroup analysis, patients eligible for statin therapy were divided into 2 subgroups according to administration status.

RESULTS

There were 149 (81.9%) patients in the healed group and 33 (18.1%) in the retear group. In the multiple regression analysis, missed statin therapy, 10-year ASCVD risk score, and fatty infiltration of the infraspinatus muscle were the independent factors related to retear. The cutoff value for 10-year ASCVD risk score was 11.85%, with a sensitivity of 0.75 and a specificity of 0.62. In the subgroup analysis of 104 patients eligible for statin therapy, 66 (63.5%; group 1) received statin therapy and 38 (36.5%; group 2) missed it. Group 2 showed a significantly higher retear rate than group 1 (36.8% vs 13.6%; P = .006).

CONCLUSION

Missed statin therapy, 10-year ASCVD risk score, and fatty infiltration of the infraspinatus were the independent factors associated with rotator cuff retear. Patients who missed statin therapy showed a higher retear rate than patients receiving statin therapy. Optimal statin therapy for patients who undergo arthroscopic rotator cuff repair might improve repair integrity.

Using the Practical Robust Implementation and Sustainability Model (PRISM) to Identify and Address Provider-Perceived Barriers to Optimal Statin Prescribing and Use in Community Health Centers

Statins are an important but underutilized therapy to prevent cardiovascular events, particularly in high-risk patients. To increase use of statin therapy in high-risk patients, the Centers for Disease Control and Prevention funded a project led by the National Association of Community Health Centers to discover reasons for statin underuse in health centers and identify possible leverage points, particularly among vulnerable and underserved patients. The project further sought to develop training and educational materials to improve statin prescribing for and acceptance in eligible high-risk patients. As a first step, investigators implemented a questionnaire to clinical providers (n = 45) at health centers participating in the project to obtain their perspective on barriers to optimal statin use. We used the practical robust implementation and sustainability model (PRISM) domains to frame the overall project and guide the development of our questionnaire. This paper summarizes top perceived barriers to patient and health system/provider statin initiation and sustainment, as well as facilitators to prescribing, using PRISM as an organizing framework. Our questionnaire yielded important suggestions related to public awareness, education materials, health information technology (HIT)/data solutions, and clinical guidelines as key factors in optimizing statin use. It also informed the design of patient education resources and provider training tools. Future directions include using the full application of the PRISM implementation science model to assess how well our educational and training resources help overcome barriers to statin use in high-risk patients, including evaluating how key contextual factors influence successful implementation.

Prognostic Role of Polyvascular Involvement in Patients with Symptomatic Peripheral Artery Disease

Background: Statin therapy is recommended for patients with peripheral artery disease (PAD). However, PAD patients with polyvascular (PV) extent remain threatened by an increased residual cardiovascular (CV) risk. Purpose: To investigate the association of prescribed statin therapy and mortality in PAD patients with or without PV extent. Methods: A single-center retrospective longitudinal observational study originating from a consecutive registry with 1380 symptomatic PAD patients over a mean observational time of 60 ± 32 months. The association of atherosclerotic extent and statin use (PAD, plus one additional region (CAD or CeVD, [+1 V]), +2 vascular regions (+CAD and CeVD [+2 V]) with the risk of all-cause mortality was evaluated using Cox proportional hazard models adjusted for potential confounding factors. Results: The mean age of the study's participants was 72.0 ± 11.7 years, with 36% being female. PAD patients with PV extent [+1 V] and [+2 V] were older and suffered from diabetes, hypertension, or dyslipidemia more often; they, too, had more severely impaired kidney function (all p < 0.0001) compared to patients with PAD only. PAD patients with PV [+1 V] and [+2 V] received better statin medication and reached the recommended LDL-C target compared to PAD-only patients (p < 0.001). Despite better statin treatment, the rate of all-cause mortality was higher in PV patients than in PAD-only patients (PAD only: 13%; [+1 V]: 22%; [+2 V]: 35%; p < 0.0001). Conclusion: PV patients receive better statin therapy than PAD-only patients but nevertheless still have higher mortality rates. Future studies are needed to explore whether more aggressive LDL-lowering treatment for PAD patients may be translated into better prognosis.

Disparate statin prescribing following hospital discharge for stroke or transient ischemic attack: Findings from COMPASS

BACKGROUND

Published guidelines recommend high-intensity statins following an ischemic stroke or transient ischemic attack (TIA). The authors examined the potential for disparate patterns of statin prescribing in a cluster randomized trial of transitional care following acute stroke or TIA.

METHODS

Medications taken before hospitalization and statins prescribed at discharge among stroke and TIA patients at 27 participating hospitals were examined. Any statin and intensive statin prescribed at discharge were compared by age (<65, 65-75, >75 years), racial category (White vs. Black), sex (male vs. female), and rurality (urban vs. non-urban) using logistic mixed models.

RESULTS

Among 3211 patients (mean age 67 years; 47% female; 29% Black), 90% and 55%, respectively, were prescribed any statin or intensive statin therapy at discharge. White (vs. Black) patients (0.71, 0.51-0.98) less commonly received any statin prescription, while stroke (vs. TIA) patients (1.90, 1.38-2.62) and those residing in urban areas (1.66, 1.07-2.55) more commonly received any statin prescription. Among those prescribed a statin, only 42% of White and 51% of Black patients >75 years. were prescribed an intensive statin; the OR for intensive statin prescribing was 0.44 for patients >75 years and was similar in a subgroup not on a statin previously.

CONCLUSION/RELEVANCE

Following stroke or TIA, statin prescribing remains lower in White patients, in those with TIA, and in those in non-urban areas. Intensive statin prescribing remains limited, particularly in patients >75 years. These data may inform efforts to improve guideline concordant prescribing for post-stroke patients.

Low-Intensity Statin Therapy and Changes in Coronary Artery Calcification Density after One Year

Background: Statin therapy promotes the progression of coronary artery calcification (CAC). Comparing patients on high (HIST) vs. low-to-intermediate intensity statin therapy (LIST), randomized controlled trials with a one-year follow-up failed to document a relevant difference in the Agatston score and CAC volume. We evaluated whether statin intensity modifies CAC density at one year. Methods: We performed a pooled analysis of two randomized-controlled trials (BELLES, EBEAT), comparing the effects of HIST (Atorvastatin 80 mg) vs. LIST (Pravastatin 40 mg, Atorvastatin 10 mg) on CAC measures after one year. The differences in CAC density and its change were compared using the two-sided t-test. Results: Data from 852 patients (66.7% female) with available baseline and follow-up CT were evaluated from both trials. HIST vs. LIST more effectively reduced LDL-cholesterol (annualized change: −45.8 ± 38.5 vs. −72.9 ± 46.0 mg/dL, p < 0.001). Mean CAC density increased from 228.8 ± 35.4 HU to 232.6 ± 37.0 HU (p < 0.0001) at one-year follow-up. Comparing patients on HIST vs. LIST, CAC density at follow-up (HIST: 231.9 ± 36.1 HU vs. LIST: 233.3 ± 37.7 HU, p = 0.59) and its change from baseline (HIST: 4.0 ± 19.1 HU vs. LIST: 3.6 ± 19.6 HU, p = 0.73) did not differ. Subgroup analyses, stratifying by LDL reduction (<median: 2.0 ± 24.3 HU, ≥median: 3.6 ± 21.9 HU, p = 0.34), Agatston score at baseline (<100: 2.6 ± 22.5 HU vs. 3.2 ± 25.6 HU, p = 0.82; ≥100: 4.8 ± 17.0 HU vs. 3.8 ± 16.6 HU, p = 0.44, for HIST vs. LIST; respectively), and equal number of lesions in both CT scans (3.7 ± 20.3 HU vs. 7.0 ± 22.2 HU, p = 0.24) showed similar results. Conclusion: HIST vs. LIST leads to a higher reduction in cholesterol levels, which does not translate into relevant differences in the change of CAC density at one-year follow-up.

The association of lipid-lowering therapy and blood pressure control among outpatients with hypertension at the Felege Hiwot Comprehensive Specialized Hospital, Northwest Ethiopia

Background

The lipid-lowering medications known as statins have been shown in controlled clinical trials to have pleiotropic properties, such as lowering blood pressure, in addition to lowering cholesterol levels. The purpose of this study was to see if there was a possible link between blood pressure control and statin therapy in outpatients with hypertension in a real clinical setting.

Patients and methods

A retrospective comparative cohort study of 404 patients with hypertension was carried out. A systematic random sampling technique was used. For data entry, Epi-Data version 4.6 was used, and SPSS version 25 was used for further analysis. For group comparisons, chi-square and independent t-tests were computed. To determine the relationship between statin use and blood pressure control, a binary logistic regression model was employed. To declare statistical significance, a 95% confidence interval and a P-value of <0.05 were used.

Results

Half of the study participants who were using a prescribed statin were assigned to the statin group, whereas the remaining participants who do not take statins were assigned to the control group. After 3 months of statin treatment, BP control to <130/80 mmHg was significantly greater (P = 0.022) in the statin group (52.5%) than in the control group (41.0%). The use of statins raises the likelihood of having blood pressure under control by 1.58 times when compared to statin non-users. After controlling for possible confounders, statin therapy still increased the odds of having controlled BP by a factor of 5.98 [OR = 5.98; 95% CI: 2.77-12.92].

Conclusion

This study revealed that blood pressure control was higher among statin user hypertensive patients. Favorable effects of statin use were independently observed, even after correction for age, presence of dyslipidemia, and duration of antihypertensive therapy. Therefore, the importance of concomitantly added lipid-lowering drugs such as statins and their role in managing poor blood pressure control should be given due emphasis.

Effect of Atorvastatin on Serial Changes in Coronary Physiology and Plaque Parameters

BACKGROUND

The effects of statin on coronary physiology have not been well evaluated.

OBJECTIVES

The authors performed this prospective study to investigate changes in coronary flow indexes and plaque parameters, and their associations with atorvastatin therapy in patients with coronary artery disease (CAD).

METHODS

Ninety-five patients with intermediate CAD who received atorvastatin therapy underwent comprehensive physiological assessments with fractional flow reserve (FFR), coronary flow reserve, index of microcirculatory resistance, and intravascular ultrasound at the index procedure, and underwent the same evaluations at 12-month follow-up. Optimal low-density lipoprotein cholesterol (LDL-C) was defined as LDL-C <70 mg/dL or ≥50% reduction from the baseline. The primary endpoint was a change in the FFR.

RESULTS

Baseline FFR, minimal lumen area, and percent atheroma volume (PAV) were 0.88 ± 0.05, 3.87 ± 1.28, 55.92 ± 7.30, respectively. During 12 months, the percent change in LDL-C was -33.2%, whereas FFR was unchanged (0.87 ± 0.06 at 12 months; P = 0.694). Vessel area, lumen area, and PAV were significantly decreased (all P values <0.05). The achieved LDL-C level and the change of PAV showed significant inverse correlations with the change in FFR. In patients with optimally modified LDL-C, the FFR had increased (0.87 ± 0.06 vs 0.89 ± 0.07; P = 0.014) and the PAV decreased (56.81 ± 6.44% vs 55.18 ± 8.19%; P = 0.031), whereas in all other patients, the FFR had decreased (0.88 ± 0.05 vs 0.86 ± 0.06; P = 0.025) and the PAV remained unchanged.

CONCLUSIONS

In patients with CAD, atorvastatin did not change FFR despite a decrease in the PAV. However, in patients who achieved the optimal LDL-C target level with atorvastatin, the FFR had significantly increased with decrease of the PAV.

Review of Under-Recognized Adjunctive Therapies for Cancer

Patients and providers may not be aware that several adjunctive measures can significantly improve the quality of life, response to treatment, and possibly outcomes for cancer patients. This manuscript presents a review of practical under-recognized adjunctive therapies that are effective including exercise; stress-reduction techniques such as mindfulness, massage, yoga, Tai Chi, breathing exercises; importance of sleep quality; diet modifications such as calorie restriction at the time of chemotherapy and avoidance of high carbohydrate foods; supplements such as aspirin, green tea, turmeric, and melatonin; and repurposed prescription medications such as metformin and statins. Each recommendation should be tailored to the individual patient to assure no contraindications.

Pharmacotherapy for children with elevated levels of lipoprotein(a): future directions

INTRODUCTION

Elevated lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD). With the advent of the antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs) targeted at LPA, the gene encoding apolipoprotein(a), that are highly effective for lowering Lp(a) levels, this risk factor might be managed in the near future. Given that Lp(a) levels are mostly genetically determined and once elevated, present from early age, we have evaluated future directions for the treatment of children with high Lp(a) levels.

AREAS COVERED

In the current review, we discuss different pharmacological treatments in clinical development and provide an in-depth overview of the effects of ASOs and siRNAs targeted at LPA.

EXPERT OPINION

Since high Lp(a) is an important risk factor for ASCVD and given the promising effects of both ASOs and siRNAs targeted at apo(a), there is an urgent need for well-designed prospective studies to assess the impact of elevated Lp(a) in childhood. If the Lp(a)-hypothesis is confirmed in adults, and also in children, the rationale might arise for treating children with high Lp(a) levels. However, we feel that this should be limited to children with the highest cardiovascular risk including familial hypercholesterolemia and potentially pediatric stroke.

Effects of statins on the inducible degrader of low-density lipoprotein receptor in familial hypercholesterolemia

The inducible degrader of low-density lipoprotein receptor (IDOL) is an E3 ubiquitin ligase involved in the post-transcriptional regulation of LDL receptor (LDLR). Statins lower plasma LDL by activating transcription of hepatic LDLR expression, and we have determined whether statins modulate IDOL expression and influence LDLR protein abundance. IDOL expression in monocytes and serum IDOL level was determined in statin-treated familial hypercholesterolemia (FH) patients and compared with control subjects. Serum IDOL level was also evaluated in a group of untreated FH patients before and after the initiation of statin. The mechanism underlying the inhibitory effect of statin on IDOL expression was investigated in vitro. In statin-treated FH patients, serum IDOL level and its expression in monocytes was reduced compared with control (P < 0.05). In contrast, untreated FH patients had higher serum levels of IDOL and proprotein convertase subtilisin/kexintype 9 (PCSK9) than control (P < 0.05), and serum IDOL level decreased after statin therapy (P < 0.05) whereas an increase was observed in PCSK9 level (P < 0.01). In vitro, atorvastatin significantly decreased IDOL abundance in a dose-dependent manner in cultured macrophages and hepatocytes with a concomitant increase in LDLR expression. The transcription of IDOL was restored by adding either an LXR agonist T0901317 or oxysterol 22(R)-hydroxycholesterol, indicating that statin inhibited IDOL expression by reducing LXR activation. The LXR-IDOL-LDLR axis can be modulated by statins in vitro and in vivo. Statins inhibit IDOL expression by reducing LXR activation and upregulate LDLR, and statins exert the opposite effect on IDOL and PCSK9.

Knowledge, attitude, perceived barriers, and practices among pharmacists regarding risk assessment of cardiovascular disease: a cross-sectional study in Yemen

BACKGROUND

Risk evaluation of atherosclerotic cardiovascular diseases can guide the decision-making on various preventive measures, such as initiating or deferring statin therapy. Pharmacists can play an active part in the risk evaluation and primary prevention of atherosclerotic cardiovascular diseases. Thus, our study aimed to assess the pharmacists' knowledge, attitude, perceived barriers, and practices regarding risk assessment of atherosclerotic cardiovascular disease.

MATERIALS AND METHODS

A cross-sectional study was conducted among 500 pharmacists using a structured validated questionnaire between November 2020 and February 2021. The Mann-Whitney and Kruskal-Wallis tests were used to analyze the data.

RESULTS

A total of 456 pharmacists completed the questionnaire out of 500 distributed (91.2% response rate). Over 60% of participants responded with never or rarely for two out of five cardiovascular diseases (CVD) prevention practices. The lowest pharmacist-patient counseling practices were for side effects of statin medication (14.5%) and reviewing the patient's medications to avoid potential statin-drug interactions (31.8%). Participants had a high positive attitude (median = 34 out of 40). The three major barriers for risk assessment were the lack of support (74.8%), the lack of resources (70.6%), and inadequate training (48.7%). Interestingly, having ≤75 customers a day, community pharmacies, PharmD degree, age ≥30 years, and experience ≥6 years were significantly associated (p < .05) with higher CVD prevention activities and counseling practices.

CONCLUSION

Pharmacists have a high positive attitude toward CVD risk assessment. However, they had insufficient knowledge and only provided limited activities and counseling services for CVD prevention and statin therapy. Participants perceived several barriers to CVD risk assessment services in pharmacies. Therefore, it is necessary to remove these impediments for pharmacists to be more involved in CVD risk assessment and prevention. Also, continuing medical education and adequate training for pharmacists are required.

Effects of High- or Moderate-intensity Rosuvastatin on 1-year Major Adverse Cardiovascular Events Post-percutaneous Coronary Intervention

Background: Although statins decrease mortality in coronary artery disease, the effect of high-dose statins and duration of therapy post-percutaneous coronary intervention (PCI) is not well addressed. Aim: To determine the effective dose of statin to prevent major adverse cardiovascular events (MACEs), such as acute coronary syndrome, stroke, myocardial infarction, revascularisation and cardiac death, after PCI in patients with chronic coronary syndrome. Methods: In this randomised, double-blind clinical trial, all chronic coronary syndrome patients with a recent history of PCI were randomly divided into two groups after 1 month of high-dose rosuvastatin therapy. Over the next year, the first group received rosuvastatin 5 mg daily (moderate intensity), while the second received rosuvastatin 40 mg daily (high intensity). Participants were evaluated in terms of high-sensitivity C-reactive protein and MACEs. Results: The 582 eligible patients were divided into group 1 (n=295) and group 2 (n=287). There was no significant difference between the two groups in terms of sex, age, hypertension, diabetes, smoking, previous history of PCI or history of coronary artery bypass grafting (p>0.05). There were no statistically significant differences in MACE and high-sensitivity C-reactive protein after 1 year between the two groups (p=0.66). Conclusion: The high-dose group had lower LDL levels. However, given the lack of association between high-intensity statins and MACEs in the first year after PCI among chronic coronary syndrome patients, the use of moderate-intensity statins may be as effective as high-intensity statins, and treatment based on LDL targets may suffice.

Adherence to Clinical Guidelines on STATIN Prescribing Among Diabetic Patients Aged 40-75 Years Old in a Primary Care Setting: A Cross-Sectional Study

BACKGROUND

Diabetes mellitus (D.M.) is a chronic metabolic disease caused by decreased insulin secretion, which increases the risk of cardiovascular diseases. Evidence has shown that statins reduce cardiovascular risk in patients with diabetes; moreover, most clinical guidelines recommend statins.

OBJECTIVE

This study aimed to assess the level and status of adherence to guidelines on statin prescription in patients with diabetes mellitus in a primary care setting in Palestine.

METHODS

A retrospective cross-sectional descriptive study was conducted at an ambulatory center in Palestine. Data were collected by auditing prescription records and reviewing medical charts of patients with diabetes who visited the clinic from February 15 to March 17, 2021. The collected data included patient characteristics, comorbidities, lipid profiles, and statin prescription. A chi-square test was used to evaluate the appropriateness of the prescribed statins with different demographic and clinical variables. Statistical significance was set at p < 0.05. Statistical Package for Social Sciences (SPSS) version 22 was used to analyze the data.

RESULTS

Out Of 262 diabetic patients included in the analysis, 74% were prescribed appropriate statin therapy according to the American Diabetes Association (ADA) guidelines, and 24% of patients had inappropriate statin therapy or needed statins. Furthermore, 82.8% were on high-intensity statins, while 11% were not taking any statins. More than 60% of patients had uncontrolled diabetes and hypertension.

CONCLUSION

Most guidelines recommend statin therapy in diabetic patients owing to its benefits in preventing cardiovascular complications. In this study, most patients were on appropriate STATIN therapy; however, 50% of diabetic patients had LDL of more than 100 mg/dl, and 25% were not prescribed statins, increasing their risk of ASCVD. Therefore, we recommend strict adherence to the established guidelines on statins prescribed to patients with diabetes to prevent cardiovascular complications, save lives, and reduce healthcare costs.

Prevention of Osteoarthritis Progression by Statins, Targeting Metabolic and Inflammatory Aspects: A Review

Background and purpose:

Several traditional risk factors of atherosclerosis such as age, obesity, and altered lipid metabolism are shared with osteoarthritis (OA). Metabolic abnormalities and atheromatous vascular disease are linked with systemic inflammation and progression of OA. Hence, treatment of OA with statins is expected to improve metabolic abnormalities and prevent OA progression. Many studies which have addressed this issue found inconsistent results. This review aims to elucidate the effect of statins in OA by summarizing the existing data.

Methods:

Potential studies in English language published in Medline/PubMed, Scopus and Google Scholar since 2000 were searched by using keywords such as osteoarthritis, statins, progression, treatment, prevalence, synovitis, pain. Fourteen papers were found to be relevant and were summarised.

Results:

Data regarding symptomatic effect of statins in OA are scarce and the results varied from no effect to a small improvement or even increased risk of pain in knee OA. However, most studies on the incidence and progression of OA found a significant decreased risk of incident OA, as well as reduced risk of radiographic progression in statin users vs. non-users. Factors such as patient adherence, duration of treatment, and higher cumulative statin doses were associated with greater efficacy.

Conclusion:

Existing data indicate a preventing effect of statin therapy on OA progression. However, unless a formal meta-analysis with weight analysis is made, a conclusion cannot be drawn.

Acute Secondary Prevention of Ischemic Stroke: Overlooked No Longer

Recent studies of interventions initiated acutely following onset of minor ischemic stroke or transient ischemic attack (TIA) have disclosed early stroke recurrence rates that are substantially higher than long-term recurrence rates and that can be reduced by acute antiplatelet treatment interventions. These observations, bolstered by analysis based on kinetic modeling of the time course of recurrence following initial events, suggest that acute stroke patients experience an underlying vulnerable state that quickly transitions to a more stable state. Some evidence also supports the benefits of early treatment with direct-acting oral anticoagulants in cardioembolic stroke and of continuation or early initiation of statin therapy in atherosclerotic stroke. Treatment of ischemic stroke should address the transient vulnerable state that follows the initial event, employing measures aiming to avert early recurrence of thromboembolism and to promote stabilization of vulnerable arterial plaque. These measures constitute acute secondary prevention following ischemic stroke.

Association between incidental statin use and skeletal myopathies in patients treated with immune checkpoint inhibitors

Objectives

Skeletal myopathies are highly morbid, and in rare cases even fatal, immune-related adverse events (irAE) associated with immune checkpoint inhibitors (ICI). Skeletal myopathies are also a recognized statin-associated side effect. It is unknown whether concurrent use of statins and ICIs increases the risk of skeletal myopathies.

Methods

This was a retrospective cohort study of all patients who were treated with an ICI at a single academic institution (Massachusetts General Hospital, Boston, MA, USA). The primary outcome of interest was the development of a skeletal myopathy. The secondary outcome of interest was an elevated creatine kinase level (above the upper limit of normal).

Results

Among 2757 patients, 861 (31.2%) were treated with a statin at the time of ICI start. Statin users were older, more likely to be male and had a higher prevalence of cardiovascular and non-cardiovascular co-morbidities. During a median follow-up of 194 days (inter quartile range 65–410), a skeletal myopathy occurred in 33 patients (1.2%) and was more common among statin users (2.7 vs. 0.9%, P < 0.001). Creatine kinase (CK) elevation was present in 16.3% (114/699) and was higher among statin users (20.0 vs. 14.3%, P = 0.067). In a multivariable Cox model, statin therapy was associated with a >2-fold higher risk for skeletal myopathy (HR, 2.19; 95% confidence interval, 1.07–4.50; P = 0.033).

Conclusion

In this large cohort of ICI-treated patients, a higher risk was observed for skeletal myopathies and elevation in CK levels in patients undergoing concurrent statin therapy. Prospective observational studies are warranted to further elucidate the potential association between statin use and ICI-associated myopathies.

The Effect of Statin Therapy on Inflammatory Biomarkers: A Systematic Review

3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase inhibitors are commonly used drugs in the management of elevated lipid levels and cardiovascular disease. In cardiovascular diseases, among other common chronic conditions, inflammatory biomarkers are used to monitor disease progression and the risk of recurrent adverse events. We explored whether or not there was a positive effect on these biomarkers using HMG-CoA reductase inhibitors. The systematic review was conducted by gathering relevant papers mainly from three databases, identified through a generated Medical Subject Headings (MeSH) strategy. Identification of papers was subsequently followed by applying a selected inclusion and exclusion criteria to narrow the papers chosen for review. Post the application of stipulated criteria, 12 papers remained. They were subsequently assessed for risk of bias using a Cochrane risk analysis tool, identifying most as having some concerns of bias or low risk of bias. We found that HMG-CoA reductase inhibitors exhibit both a lipid-lowering effect addition to an anti-inflammatory effect.

Statin Use and Long-Term Mortality after Rectal Cancer Surgery

BACKGROUND

The current study aimed to assess the association between regular statin therapy and postoperative long-term all-cause and cancer-specific mortality following curative surgery for rectal cancer. The hypothesis was that statin exposure would be associated with better survival.

METHODS

Patients with stage I-III rectal cancer undergoing surgical resection with curative intent were extracted from the nationwide, prospectively collected, Swedish Colorectal Cancer Register (SCRCR) for the period from January 2007 and October 2016. Patients were defined as having ongoing statin therapy if they had filled a statin prescription within 12 months before and after surgery. Cox proportional hazards models were employed to investigate the association between statin use and postoperative five-year all-cause and cancer-specific mortality.

RESULTS

The cohort consisted of 10,743 patients who underwent a surgical resection with curative intent for rectal cancer. Twenty-six percent (n = 2797) were classified as having ongoing statin therapy. Statin users had a considerably decreased risk of all-cause (adjusted hazard ratio (HR) 0.66, 95% confidence interval (CI): 0.60-0.73, p < 0.001) and cancer-specific (adjusted HR 0.60, 95% CI: 0.47-0.75, p < 0.001) mortality up to five years following surgery.

CONCLUSIONS

Statin use was associated with a lower risk of both all-cause and rectal cancer-specific mortality following curative surgical resections for rectal cancer. The findings should be confirmed in future prospective clinical trials.

Preadmission Statin Therapy and Clinical Outcome in Hospitalized Patients With COVID-19: An Italian Multicenter Observational Study

ABSTRACT

Statin therapy has been recently suggested as possible adjuvant treatment to improve the clinical outcome in patients with coronavirus disease 2019 (COVID-19). The aim of this study was to describe the prevalence of preadmission statin therapy in hospitalized patients with COVID-19 and to investigate its potential association with acute distress respiratory syndrome (ARDS) at admission and in-hospital mortality. We retrospectively recruited 467 patients with laboratory-confirmed COVID-19 admitted to the emergency department of 10 Italian hospitals. The study population was divided in 2 groups according to the ARDS diagnosis at admission and in-hospital mortality. A multivariable regression analysis was performed to assess the risk of ARDS at admission and death during hospitalization among patients with COVID-19. A competing risk analysis in patients taking or not statins before admission was also performed. ARDS at admission was reported in 122 cases (26.1%). There was no statistically significant difference for clinical characteristics between patients presenting with and without ARDS. One hundred seven patients (18.5%) died during the hospitalization; they showed increased age (69.6 ± 13.1 vs. 66.1 ± 14.9; P = 0.001), coronary artery disease (23.4% vs. 12.8%; P = 0.012), and chronic kidney disease (20.6% vs. 11.1%; P = 0.018) prevalence; moreover, they presented more frequently ARDS at admission (48.6% vs. 19.4%; P < 0.001). At multivariable regression model, statin therapy was not associated neither with ARDS at admission nor with in-hospital mortality. Preadmission statin therapy does not seem to show a protective effect in severe forms of COVID-19 complicated by ARDS at presentation and rapidly evolving toward death.

Postoperative Myocardial Injury in Patients Classified as Low Risk Preoperatively Is Associated With a Particularly Increased Risk of Long-Term Mortality After Noncardiac Surgery

Background

Prior studies have shown an association between myocardial injury after noncardiac surgery (MINS) and all‐cause mortality in patients following noncardiac surgery. However, the association between preoperative risk assessments, Revised Cardiac Risk Index and American College of Surgeons National Surgical Quality Improvement Program, and postoperative troponin elevations and long‐term mortality is unknown.

Methods and Results

A retrospective chart review identified 548 patients who had a troponin I level drawn within 14 days of noncardiac surgery that required an overnight hospital stay. Patients aged 40 to 80 years with at least 2 cardiovascular risk factors were included, while those with trauma, pulmonary embolism, and neurosurgery were excluded. Kaplan–Meier survival and odds ratio (OR) with sensitivity/specificity analysis were performed to assess the association between preoperative risk and postoperative troponin elevation and all‐cause mortality at 1 year. Overall, 69%/31% were classified as low‐risk/high‐risk per the Revised Cardiac Risk Index and 66%/34% per American College of Surgeons National Surgical Quality Improvement Program. Comparing the low‐risk versus high‐risk groups, preoperative risk assessment was not associated with either postoperative troponin elevation or 1‐year mortality. MINS portended a 1‐year mortality of OR, 3.9 (95% CI, 2.44–6.33) in the total population. Patients classified as low risk preoperatively with MINS had the highest risk of 1‐year mortality (OR, 9.6; 95% CI, 4.27–24.38), with a low prevalence of statin use.

Conclusions

Current preoperative risk stratification tools do not prognosticate the risk of postoperative troponin elevation and all‐cause mortality at 1 year. Interestingly, patients classified as low risk preoperatively with MINS had a markedly higher 1‐year mortality risk compared with the general population, and most of them are not taking a statin. Our results suggest that evaluating preoperatively low‐risk patients for MINS presents an opportunity for prognostication, risk reclassification, and initiating therapies such as statins to mitigate long‐term risk.

Coronary Calcium Risk Score and Cardiovascular Risk

The association between the presence of coronary artery calcium (CAC) and the risk of coronary artery disease (CAD) has been appreciated for decades. In this review, we critically appraise the role of CAC based on computerized tomography in contemporary risk stratification. Available evidence suggests that the measurement of CAC is a useful modality in many patients for more precise risk stratification and prognostic determination. Whether newer CAC score incorporating extra coronary calcification will add incremental value, especially for stroke and other non-coronary vascular outcomes, needs a prospective study.

Prospective evaluation of lipid management following acute coronary syndrome in non-Western countries

Background

Half the global burden of cardiovascular disease (CVD) is concentrated in the Asia‐Pacific (APAC) region.

Hypothesis

Suboptimal control of low‐density lipoprotein cholesterol (LDL‐C) may play a large role in the burden of CVD in APAC and non‐Western countries.

Methods

The Acute Coronary Syndrome Management (ACOSYM) registry is a multinational, multicenter, prospective observational registry designed to evaluate LDL‐C control in patients within 6 months after hospitalization following an acute coronary syndrome (ACS) event across nine countries.

Results

Overall, 1581 patients were enrolled, of whom 1567 patients met the eligibility criteria; 80.3% of the eligible patients were men, 46.1% had ST‐elevation myocardial infarction, and 39.5% had non‐ST‐elevation myocardial infarction. Most (1245; 79.5%) patients were discharged on a high‐intensity statin. During the follow‐up, only 992 (63.3%) patients had at least one LDL‐C measurement; of these, 52.9% had persistently elevated LDL‐C (>70 mg/dl). The patients not discharged on a high‐dose statin were more likely (OR 3.2; 95% CI 2.1–4.8) to have an LDL‐C above the 70 mg/dl LDL‐C target compared with those who were discharged on a high‐dose statin.

Conclusion

Our real‐world registry found that a third or more of post‐ACS patients did not have a repeat LDL‐C follow‐up measurement. In those with an LDL‐C follow‐up measurement, more than half (52.9%) were not achieving a <70 mg/dl LDL‐C goal, despite a greater uptake of high‐intensity statin therapy than has been observed in recent evidence. This demonstrates the opportunity to improve post‐ACS lipid management in global community practice.

Clinical Pharmacist Outreach to Increase Statin Use for Patients with Cardiovascular Disease in a Safety-Net Healthcare System

BACKGROUND

Statin Therapy for Patients with Cardiovascular Disease (SPC) is a Centers for Medicare & Medicaid Services Star measure added to Medicare Part C (Medicare Advantage) plans in 2019 to incentivize statin use for secondary prevention of cardiovascular disease (CVD). The measure assesses statin dispensing and adherence in patients with atherosclerotic CVD (ASCVD). Clinical pharmacists are well-positioned to affect positively a health system's performance on the SPC measure.

OBJECTIVE

To assess the effect of telephone outreach by clinical pharmacists on moderate- or high-intensity statin prescribing in patients with ASCVD.

METHODS

Patients in managed care health plans who meet the SPC measure criteria and are not currently receiving a moderate- to high-intensity statin therapy were contacted by a clinical pharmacist through telephone outreach. If appropriate, they were prescribed a statin by a clinical pharmacist. The primary outcome measure was the proportion of patients who meet the SPC measure classification and had 1 confirmed prescription fill for a moderate- or high-intensity statin after intervention by a clinical pharmacist.

RESULTS

A total of 84 patients were identified for review and outreach, of whom 35 (41.7%) met the SPC measure criteria. Of these 35 patients, 16 (45.7%) were female and the mean age was 66 years. A total of 22 (62.9%) patients agreed to a statin prescription, and 16 (72.7%) of these patients picked up the prescription within 10 days of prescribing. An additional 4 patients, for a total of 20 (57.1%) of the 35 eligible patients, were eventually dispensed a statin. Healthcare Effectiveness Data and Information Set (HEDIS) vendor data available after the intervention showed a larger SPC measure population than was captured with the health plan's internal report. HEDIS data showed an increase in statin prescribing for patients meeting the SPC measure classification from 24.7% to 56.6% during the study period (P <.001). The mean time spent per patient for chart review and/or outreach by the clinical pharmacist was 27.7 (standard deviation, 9) minutes.

CONCLUSION

These results indicate that clinical pharmacists who conduct a telephonic population health intervention can achieve a high rate of success in initiating a moderate- to high-intensity statin therapy in patients with ASCVD.

PCSK9 Levels and Metabolic Profiles in Elderly Subjects with Different Glucose Tolerance under Statin Therapy

Proprotein convertase subtilisin/kexin type 9 (PCSK9) degrades low-density lipoprotein cholesterol (LDL-C) receptors, and thus regulates the LDL-C levels in the circulation. Type 2 diabetics often have elevated LDL-C levels. However, the functions of PCSK9 in patients with alterations of glu-cose metabolism and statin therapy are still unclear. Method: we investigated a large cohort of 608 subjects, born in 1945 in Oulu, Finland (Oulu Cohort 1945). We studied the effects of PSCK9 lev-els with different glucose tolerances (normal glucose tolerance (NGT), prediabetes (PreDM) or type 2 diabetes (T2D)) with and without statin medication, and analyzed clinical data, NMR metabolomics and PCSK9 plasma levels. Results: PCSK9 plasma levels did not significantly differ between the three groups. Statin therapy significantly increased the PCSK9 levels in NGT, PreDM and T2D groups compared with subjects with no statins. In the NGT group, negative associations between PCSK9 and LDL-C, intermediate-density lipoprotein cholesterol (IDL-C), very low-density lipoprotein cholesterol (VLDL-C), total cholesterol and LDL and IDL triglycerides were observed under statin medication. In contrast, in the PreDM and T2D groups, these associa-tions were lost. Conclusions: our data suggest that in subjects with abnormal glucose metabolism and statin therapy, the significant PCSK9-mediated effects on the lipid metabolites are lost com-pared to NGT subjects, but statins reduced the LDL-C and VLDL-C levels.

Performance of Guideline Recommendations for Prevention of Myocardial Infarction in Young Adults

BACKGROUND

The 2018 cholesterol guidelines of the American Heart Association and the American College of Cardiology (AHA/ACC) changed 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitor (statin) eligibility criteria for primary prevention to include multiple risk enhancers and novel intensive lipid-lowering therapies for secondary prevention.

OBJECTIVES

This study sought to determine how guideline changes affected identification for preventive therapy in young adults with premature myocardial infarction (MI).

METHODS

The study identified adults presenting with first MI at Duke University Medical Center in Durham, North Carolina. Statin therapy eligibility was determined using the 2013 ACC/AHA and 2018 AHA/ACC guidelines criteria. The study also determined potential eligibility for intensive lipid-lowering therapies (very high risk) under the 2018 AHA/ACC guidelines, by assessing the composite of all-cause death, recurrent MI, or stroke rates in adults considered "very high risk" versus not.

RESULTS

Among 6,639 patients with MI, 41% were <55 years of age ("younger"), 35% were 55 to 65 years of age ("middle-aged"), and 24% were 66 to 75 years of age ("older"). Younger adults were more frequently smokers (52% vs. 38% vs. 22%, respectively) and obese (42% vs. 34% vs. 31%, respectively), with metabolic syndrome (21% vs. 19% vs. 17%, respectively) and higher low-density lipoprotein cholesterol (117 vs. 107 vs. 103 mg/dl, respectively) (p trend <0.01 for all). Pre-MI, fewer younger adults met guideline indications for 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitor (statin) therapy than middle-aged and older adults. The 2018 guideline identified fewer younger adults eligible for statin therapy at the time of their MI than the 2013 guideline (46.4% vs. 56.7%; p < 0.01). Younger patients less frequently met very high-risk criteria for intensive secondary prevention lipid-lowering therapy (28.3% vs. 40.0% vs. 81.4%, respectively; p < 0.01). Over a median 8 years of follow-up, very high-risk criteria were associated with increased risk of major adverse cardiovascular events in individuals <55 years of age (hazard ratio: 2.09; 95% confidence interval: 1.82 to 2.41; p < 0.001), as was the case in older age groups (p interaction = 0.54).

CONCLUSIONS

Most younger patients with premature MI are not identified as statin candidates before their event on the basis of the 2018 guidelines, and most patients with premature MI are not recommended for intensive post-MI lipid management.

Treatment and Predictors of Recurrent Internal Carotid Artery In-Stent Restenosis

PURPOSE

We aimed to examine the effectiveness of different therapeutic options for and to identify the possible risk factors of recurrent internal carotid artery (ICA) in-stent restenosis (ISR).

METHODS

Forty-six ICA ISRs, which were reintervened at least once, were retrospectively analyzed regarding clinical and imaging characteristics, as well as invasive treatment type (percutaneous transluminal angioplasty [PTA] with a plain balloon, PTA with a drug-eluting balloon [DEB], re-stenting) used.

RESULTS

The median follow-up was 29.5 months (IQR, 8.5-52.8 months) in patients who underwent reintervention for ICA ISR. Stent occlusion occurred in 3 patients (6.5%). One ISR recurrence was noted in 10 patients (21.7%); reintervention was carried out in 7 cases (7/10 [70%]; PTA, N = 5; PTA with a DEB, N = 1; re-stenting, N = 1), while 3 patients (3/10; 30%) received best medical treatment. Two ISR recurrences were observed in 3 patients (6.5%); all of them underwent reintervention (PTA, N = 1; PTA with a DEB, N = 2). Three ISR recurrences were seen in 1 patient (2.2%), who was treated with PTA. No recurrence was observed in those patients, who had DEB treatment. Multiple logistic regression analysis revealed statin therapy to be a protective factor against recurrent ISR (OR, 0.17; 95% CI, 0.03-0.84; P = .029).

CONCLUSION

Our study suggests that PTA with a DEB is the most effective for the treatment of recurrent ISR, and confirms the importance of statin use in patients who have had a carotid reintervention.

Usefulness of statins in end-stage renal disease

End-stage renal disease (ESRD) is considered an independent risk factor of cardiovascular and cerebrovascular events. This review highlights atherosclerotic risk, lipid metabolism alterations, and four studies on the use of statins in ESRD-two of which showed a statistically significant effect of statins on the primary endpoints and two of which did not. Since effects were seen with higher doses of statins, further research is needed on the protective effects of intermediate to higher doses of statins in ESRD patients.

Drugs in Context Editorial: Review of 2020 and what lies ahead in therapeutic interventions

The year 2020 was dominated by the COVID-19 pandemic, bringing with it unprecedented advancements in the fields of healthcare and therapeutic interventions as well as in vaccine and drug development. Nevertheless, several other advancements in various fields of medicine also deserve attention. Herein, the Senior Editors of Drugs in Context provide us with their expert opinion on the events of 2020 and what lies ahead in 2021.

The Effect of Long-Term Atorvastatin Therapy on Carotid Intima-Media Thickness of Children With Dyslipidemia

Carotid intima-media thickness (cIMT) has been proposed as an early marker of subclinical atherosclerosis in high risk children. Children with heterozygous familial hypercholesterolemia have greater cIMT than matched healthy controls or their unaffected siblings. Statin therapy may delay the progression of cIMT, although long-term studies in children are scarce. We evaluated the effect of atorvastatin treatment on cIMT in children with dyslipidemia. We studied 81 children/adolescents, 27 with severe dyslipidemia (low-density lipoprotein cholesterol [LDL-C] ≥190 mg/dL) and 54 sex- and age-matched healthy controls; LDL-C ≤ 130 mg/dL and lipoprotein (a), Lp(a), ≤30 mg/dL. In the children with dyslipidemia, cIMT was measured twice, before and on treatment (18.2 ± 7.7 months). Anthropometric data, a full lipid profile, liver, kidney, and thyroid function were evaluated. Males with dyslipidemia had a greater cIMT than male controls after adjustment for other factors (P = .049). In addition, a nonstatistically significant decrease in cIMT was observed after treatment (P = .261). Treatment with atorvastatin resulted in a significantly improved lipid profile. Females with dyslipidemia had a significantly thinner cIMT than males. Children with normal and high Lp(a) levels had similar cIMT values. In conclusion, treatment with atorvastatin had a beneficial effect on the lipid profile and cIMT progression in children with severe dyslipidemia.

Statins: HMG-CoA Reductase Inhibitors as Potential Anticancer Agents against Malignant Neoplasms in Women

Statins, also known as HMG-CoA inhibitors, are a class of bioactive small molecules that efficiently reduce the levels of cholesterol, and therefore are commonly used to manage and prevent various cardiovascular diseases. With respect to their original medical indications, statins are currently in the group of the most prescribed drugs worldwide. Of note is that statins are perceived actually rather as agents that have pleiotropic activities; in addition to their inhibitory activity on the production of endogenous cholesterol. Statins may also affect cell proliferation, angiogenesis and/or migration (metastasis) of different cancer cells, and play a positive role in the chemoprevention of cancer, thus being the excellent candidates to be repurposed in oncology. Particularly intriguing in this context seems to be the promising role of statins on both the incidence and course of common malignant neoplasms in women. In this article, we review and discuss the effect of the use of statins in the treatment of three types of cancer, i.e., breast, endometrial and ovarian cancer, with the highest mortality among gynecological cancers.

Long-Term Effectiveness and Safety of Initiating Statin Therapy After Index Revascularization In Patients With Peripheral Arterial Occlusive Disease

Background An increasing number of patients with a peripheral arterial occlusive disease were put on statins during the past years. This study assessed whether statin therapy was effective and safe for these new users. Methods and Results Using health insurance claims data from Germany's second-largest insurance fund, BARMER, we identified patients with peripheral arterial occlusive disease who had index revascularization between 2008 and 2018 without prior statin therapy. We compared patients with and without statin therapy in addition to antithrombotics during the first quarter after discharge (new users versus nonusers). Outcomes were all-cause mortality, cardiovascular events, and incident major amputation for effectiveness and incident diabetes mellitus and incident myopathy for safety. Propensity score matching was used to balance the study groups. All analyses were stratified into patients with chronic limb-threatening ischemia and intermittent claudication. A total of 22 208 patients (mean age 71.1 years and 50.3% women) were included in the study. In 10 922 matched patients, statin initiation was associated with lower all-cause mortality (chronic limb-threatening ischemia: hazard ratio [HR], 0.75 [95% CI, 0.68-0.84]; intermittent claudication: HR, 0.80 [95% CI, 0.70-0.92]), lower risk of major amputation in patients with chronic limb-threatening ischemia (HR, 0.73; 95% CI, 0.58-0.93) and lower risk of cardiovascular events (hazard ratio, 0.80; 95% CI, 0.70-0.92) in patients with intermittent claudication during 5 years of follow-up. Safety outcomes did not differ among the study groups. Conclusions Initiating statin therapy in patients with peripheral arterial occlusive disease after index revascularization is efficient and safe with an effect size comparable to earlier studies. Awareness campaigns for evidence-based optimal pharmacological treatment among patients are recommended.

Statins Versus Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitors- Are We Doing Better? A Systematic Review on Treatment Disparity

Coronary artery disease (CAD) is a significant contributor to mortality in America. A common risk factor of CAD is hyperlipidemia. Treatment guidelines of hyperlipidemia are well established. Statins are the cornerstone of treating hyperlipidemia. New medications such as proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9 inhibitors) have also illustrated significant results in treating hyperlipidemia. While multiple studies exemplify the disparities in statin and PCSK9 inhibitors utilization to reduce CAD mortality and risk factors, there are no systematic reviews to validate these disparities. We conducted a search on PubMed, including Medline and PubMed Central, and Google Scholar. For this analysis, we selected articles published between 2000 and 2020 and those that fit the inclusion and exclusion criteria. Based on the type of study, we performed appropriate quality assessments and deleted studies with a score of less than seven or with a high risk of biases. The search strategy resulted in 322 studies. After inclusion and exclusion criteria were applied, we included 20 articles in the analysis of this review. This systematic review demonstrates that non-white races and women were less likely to receive the correct, clinically indicated, therapy for hyperlipidemia. A multi-faceted approach is required to solve this inequality in healthcare.

Impact of lipid levels and high-intensity statins on vein graft patency after CABG: Midterm results of the ACTIVE trial

BACKGROUND

High-dose atorvastatin did not improve 1-year vein graft patency in the recent Aggressive Cholesterol Therapy to Inhibit Vein Graft Events trial. However, it remains unknown whether high-intensity statins may impact graft disease in the years that follow.

METHODS

In the trial, patients (N = 173) were randomized to receive atorvastatin 10 or 80 mg for 1 year after coronary bypass surgery (CABG). Beyond 1 year, the choice of statin was left to the patient's physician. In this study of participants who agreed to follow-up (N = 76), low-density lipoprotein (LDL) levels were measured and graft patency was assessed 3 years after surgery.

RESULTS

The rate of vein graft disease 3 years after surgery was not significantly reduced with atorvastatin 80 mg during the first postoperative year or the use of open-label high-intensity statin thereafter (p = NS). However, a trend was observed between higher LDL levels during the first postoperative year and a greater incidence of vein graft disease at 3 years (p = .12). Among patients who had LDL levels more than 90 mg/dl in the first year after CABG, 38.5% had vein graft disease at 3 years, compared to 19.0% for those with LDL levels less than 90 mg/dl (p = .15). Higher mean LDL levels during the first postoperative year were associated with a higher rate of vein disease 3 years after surgery both at the graft level (p = .03) and at the patient level (p = .03) in multivariate analysis.

CONCLUSIONS

Higher LDL levels during the first postoperative year were associated with significantly greater vein graft disease 3 years after CABG.

Treatment practices and lipid profile of patients with acute coronary syndrome: results from a tertiary care hospital

Background: Considering the increasing burden of cardiovascular risk factors and recent advances on the management of acute coronary syndromes (ACS), we studied the epidemiological characteristics and treatment strategies of patients presenting with ACS. We also evaluated the lipid profile and attainment of lipid goals in a 'real world' clinical setting.Methods: This was a substudy of IDEAL-LDL (Motivational interviewing to support low-density lipoprotein cholesterol (LDL-C) therapeutic goals and lipid-lowering therapy compliance in patients with acute coronary syndromes), a single-centre, prospective, randomised controlled trial. Baseline data from a total of 357 ACS patients were gathered using standardised methods.Results: Median age of patients was 60 years and 81.2% were males. Arterial hypertension and smoking were the most prevalent risk factors for coronary artery disease (CAD). Patients with ST-elevation myocardial infarction (STEMI) were heavier smokers, but were younger and exercised more compared to those with non-ST-elevation acute coronary syndrome (NSTE-ACS). Conversely, more NSTE-ACS patients had arterial hypertension, dyslipidaemia and diabetes mellitus. One-fifth of ACS patients was treated conservatively without a percutaneous coronary intervention (PCI). A combination of statin, dual antiplatelet therapy and beta-blockers were prescribed to 79.6% of patients upon discharge. A renin-angiotensin-aldosterone system inhibitor and a beta-blocker were prescribed to 67.3 and 91.8% of patients with LVEF ≤40%, respectively. Of patients with prior history of CAD, 63.1%, 71.4% and 58.3% received regularly statins, antiplatelets and beta-blocker treatment, respectively. Only 22.3% of these CAD patients had an optimal LDL-C of <70 mg/dl at admission.Conclusions: In hospitalised patients with ACS, management practices differed by ACS type and discharge medication was, mostly, in line with the latest guidelines. However, medication adherence and lipid lowering goals of secondary CAD prevention were largely unachieved.

Is race or ethnicity associated with under-utilization of statins among women in the United States: The study of women's health across the nation

Background

Rates of statin use among minority women are unclear.

Hypothesis

We hypothesized that statin use would vary by race/ethnicity with lower rates among minority women compared with Whites.

Methods

Data from the study of women's health across the nation, a multiethnic cohort of women collected between 2009 to 2011 were used to examine reported statin use by race/ethnicity and risk profile. Multivariable logistic modeling was performed to estimate the odds ratio (OR) of statin treatment.

Results

Of the 2399 women included, 234 had a diagnosis of atherosclerotic disease (ASCVD), 254 were diabetic (without ASCVD), 163 had an LDL ≥190 mg/dL, and 151 had a 10 year ASCVD pooled risk score ≥7.5%. Statins were used by 49.6% of women with CVD; 59.8% of women with diabetes without known ASCVD; 42.3% of women with an LDL ≥190 mg/dL; and 19.9% of women with an ASCVD risk ≥7.5%. Rates of statin use were 43.8% for women with ≥ two prior ASCVD events and 69.4% for women with ≥ one prior ASCVD event plus multiple high‐risk conditions. Among women eligible for statins, Black women had a significantly reduced adjusted odds of being on a statin (OR 0.53, 95% confidence interval [CI] 0.36‐0.78) compared with White women.

Conclusions

In this cohort of multiethnic women, rates of statin use among women who would benefit were low, with Black women having lower odds of statin use than White women.

Atorvastatin Has a Dose-Dependent Beneficial Effect on Kidney Function and Associated Cardiovascular Outcomes: Post Hoc Analysis of 6 Double-Blind Randomized Controlled Trials

Background

Kidney function decreases during the lifetime, and this decline is a powerful predictor of both kidney and cardiovascular outcomes. Statins lower cardiovascular risk, which may relate to beneficial effects on kidney function. We studied whether atorvastatin influences kidney function decline and assessed the association between individual kidney function slopes and cardiovascular outcome.

Methods and Results

Data were collected from 6 large atorvastatin cardiovascular outcome trials conducted in patients not selected for having kidney disease. Slopes of serum creatinine reciprocals representing measures of kidney function change ([mg/dL]⁻¹/y), were analyzed in 30 621 patients. Based on treatment arms, patients were categorized into 3 groups: placebo (n=10 057), atorvastatin 10 mg daily (n=12 763), and 80 mg daily (n=7801). To assess slopes, mixed‐model analyses were performed for each treatment separately, including time in years and adjustment for study. These slopes displayed linear improvement over time in all 3 groups. Slope estimates for patients randomized to placebo or atorvastatin 10 mg and 80 mg were 0.009 (0.0008), 0.011 (0.0006), and 0.014 (0.0006) (mg/dL)⁻¹/y, respectively. A head‐to‐head comparison of atorvastatin 10 and 80 mg based on data from 1 study (TNT [Treating to New Targets]; n=10 001) showed a statistically significant difference in slope between the 2 doses (P=0.0009). From a Cox proportional hazards model using slope as a predictor, a significant (P<0.0001) negative association between kidney function and cardiovascular outcomes was found.

Conclusions

In patients at risk of or with cardiovascular disease, atorvastatin improved kidney function over time in a dose‐dependent manner. In the 3 treatment groups, kidney function improvement was strongly associated with lower cardiovascular risk.

The Impact of Statin Therapy on the Survival of Patients with Gastrointestinal Cancer

Statins are 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors that may play an important role in the evolution of cancers, due to their effects on cancer cell metabolism. Statins affect several potential pathways, including cell proliferation, angiogenesis, apoptosis and metastasis. The number of trials assessing the putative clinical benefits of statins in cancer is increasing. Currently, there are several trials listed on the global trial identifier website clinicaltrials.gov. Given the compelling evidence from these trials in a variety of clinical settings, there have been calls for a clinical trial of statins in the adjuvant gastrointestinal cancer setting. However, randomized controlled trials on specific cancer types in relation to statin use, as well as studies on populations without a clinical indication for using statins, have elucidated some potential underlying biological mechanisms, and the investigation of different statins is probably warranted. It would be useful for these trials to incorporate the assessment of tumour biomarkers predictive of statin response in their design. This review summarizes the recent preclinical and clinical studies that assess the application of statins in the treatment of gastrointestinal cancers with particular emphasize on their association with cancer risk.

Association of Statin Use and Mortality After Transcatheter Aortic Valve Replacement

Background Statins may reduce mortality after transcatheter aortic valve replacement (TAVR) through prevention of atherosclerotic events or pleiotropic effects. However, the competing mortality risks in TAVR patients may dilute any positive effect of statins. We sought to understand the association of statin use with post-TAVR mortality. Methods and Results We included high- or intermediate-surgical risk patients who underwent TAVR as a part of the PARTNER (Placement of Aortic Transcatheter Valves) II and Sapien 3 trials and registries. Outcomes included 2-year all-cause, cardiovascular, and noncardiovascular mortality. We used propensity score matching to generate matched pairs between those discharged on a statin and those not on a statin after TAVR. Bias was explored with falsification end points (urinary infection, hip fracture). Among 3956 patients who underwent TAVR, we matched 626 patients on a statin with 626 patients not on a statin at discharge. Among matched patients, statin use was associated with lower risk of all-cause (hazard ratio [HR] 0.65, 95% CI 0.49-0.87, P=0.001), cardiovascular (HR 0.66, 95% CI 0.46-0.96, P=0.030), and noncardiovascular mortality (HR 0.64, 95% CI 0.44-0.99, P=0.045) compared with no statin use. The survival curves diverged within 3 months and continued to separate over a median follow-up of 2.1 years. The falsification end points were similar among groups (urinary infection, P=0.66; hip fracture, P=0.64). Conclusions In an observational, propensity-matched analysis of TAVR patients, statin use was associated with lower rates of cardiovascular and noncardiovascular mortality compared with no statin use. Given the early emergence of the apparent protective effect of statins, this result may be driven either by pleiotropic effects or by residual confounding despite propensity-matching methodology.

Patient-Reported Reasons for Declining or Discontinuing Statin Therapy: Insights From the PALM Registry

Background

Many adults eligible for statin therapy for cardiovascular disease prevention are untreated. Our objective was to investigate patient‐reported reasons for statin underutilization, including noninitiation, refusal, and discontinuation.

Methods and Results

This study included the 5693 adults recommended for statin therapy in the PALM (Patient and Provider Assessment of Lipid Management) registry. Patient surveys evaluated statin experience, reasons for declining or discontinuing statins, and beliefs about statins and cardiovascular disease risk. Overall, 1511 of 5693 adults (26.5%) were not on treatment. Of those not on a statin, 894 (59.2%) reported never being offered a statin, 153 (10.1%) declined a statin, and 464 (30.7%) had discontinued therapy. Women (relative risk: 1.22), black adults (relative risk: 1.48), and those without insurance (relative risk: 1.38) were most likely to report never being offered a statin. Fear of side effects and perceived side effects were the most common reasons cited for declining or discontinuing a statin. Compared with statin users, those who declined or discontinued statins were less likely to believe statins are safe (70.4% of current users vs. 36.9% of those who declined and 37.4% of those who discontinued) or effective (86.3%, 67.4%, and 69.1%, respectively). Willingness to take a statin was high; 67.7% of those never offered and 59.7% of patients who discontinued a statin would consider initiating or retrying a statin.

Conclusions

More than half of patients eligible for statin therapy but not on treatment reported never being offered one by their doctor. Concern about side effects was the leading reason for statin refusal or discontinuation. Many patients were willing to reconsider statin therapy if offered.

Baseline, delta, and achieved low-density lipoprotein cholesterol levels and cardiovascular risk in patients on statin therapy: A post-hoc resampling mediation analysis of treating new targets [TNT] trial

Clinical guidelines for monitoring low-density lipoprotein cholesterol (LDL-C) after statin therapy do not clearly define the clinical roles of baseline LDL-C, ΔLDL-C, and achieved LDL-C according to statin intensity. We performed post-hoc analysis of the Treating to New Target (TNT) study to evaluate individual LDL-C parameters after statin therapy. Primary outcome was the risk for total major adverse cardiovascular events (MACE). We use resampling multilevel mediation analysis to analyze complex relationships among LDL-C parameters based on similar statin intensities. Tertiles for resample A (matched baseline LDL-C; distinct achieved LDL), resample B (matched ΔLDL-C; distinct baseline LDL-C), and resample C (matched achieved LDL-C; distinct ΔLDL-C) were analyzed using Cox proportional hazard ratios. In original data analysis, the incidence of MACE was reduced in those with lower achieved LDL-C in total, low, and high intensity statin users (hazard ratios [HRs] = 0.990, 0.992, 0.992; respectively; all P-values < .001). In mediation analysis, resample A showed consistently high incidence for MACE in the middle tertile (HR = 1.237; 95% confidential interval [CI] = 1.008-1.517; P-value = .041) and highest tertile (HR = 1.275; 95% CI = 1.021-1.592; P-value = .032) compared to the lowest tertile. However, resamples B and C did not show consistent differences. Similarly, no consistent statistical difference in MACE according to statin intensity. Lower achieved LDL-C decreased MACE in participants with a similar baseline LDL-C after statin therapy. However, the change in absolute values of ΔLDL-C and achieved LDL-C should be interpreted in an individualized manner due to their complex collinearity, and statin intensity should also be taken into consideration.

Prevalence of Coronary Artery Calcification on Pre-Atrial Fibrillation Ablation CT Pulmonary Venograms and its Impact on Selection for Statin Therapy

Atherosclerotic cardiovascular disease (ASCVD) shares many risk factors with atrial fibrillation (AF). Obtaining computed tomography images of the pulmonary veins (CTPV) before AF ablation procedures is common and can incidentally detect coronary artery calcification (CAC). The purpose of this study was to investigate the prevalence of CAC on pre-ablation CTPV, the frequency of CAC reporting on CTPV reports, and its impact on statin therapy among patients hospitalized for AF procedures. We retrospectively evaluated consecutive patients undergoing CTPV and AF procedures from October 2016 to December 2017 in a single-center tertiary hospital. The patients’ demographic and clinical characteristics were analyzed. The CAC presence on CTPV was visually assessed. The severity was classified qualitatively. The statin therapy status was evaluated using the patient’s admission and discharge medication lists. A total of 638 subjects were included in our study, with 34.5% female. The mean age was 63.3 ± 10.8 years. CAC was detected in 70.1% of all patients, and in 58.1% of patients without a history of ASCVD. When present, CAC was documented in 92.6% of the clinical CTPV reports. While coronary artery atherosclerosis was present in a majority of AF patients, and its presence was widely reported, it was not associated with increased statin therapy at discharge.

From Subclinical Atherosclerosis to Plaque Progression and Acute Coronary Events: JACC State-of-the-Art Review

It has been believed that most acute coronary events result from the rupture of mildly stenotic plaques, based on studies in which angiographic information was available from many months to years before the event. However, serial studies in which angiographic data were available from the past as also within 1 to 3 months of myocardial infarction have clarified that nonobstructive lesions progressively enlarged relatively rapidly before the acute event occurred. Noninvasive computed tomography angiography imaging data have confirmed that lesions that did not progress voluminously over time rarely led to events, regardless of the extent of luminal stenosis or baseline high-risk plaque morphology. Therefore, plaque progression could be proposed as a necessary step between early, uncomplicated atherosclerosis and plaque rupture. On the other hand, it has been convincingly demonstrated that intensive lipid-lowering therapy (to a low-density lipoprotein cholesterol level of <70 mg/dl) halts plaque progression. Given the current ability to noninvasively detect the presence of early atherosclerosis, the importance of plaque progression in the pathogenesis of myocardial infarction, and the efficacy of maximum lipid-lowering therapy, it has been suggested that plaque progression is a modifiable step in the evolution of atherosclerotic plaque. A personalized approach based on the detection of early atherosclerosis can trigger the necessary treatment to prevent plaque progression and hence plaque instability. Therefore, this approach can redefine the traditional paradigm of primary and secondary prevention based on population-derived risk estimates and can potentially improve long-term outcomes.

Statin Therapy and Low-Density Lipoprotein Cholesterol Reduction after Acute Coronary Syndrome: Insights from the United Arab Emirates

Background and Aims

Attaining guideline-recommended low-density lipoprotein cholesterol (LDL-C) goals (<70 mg/dl or ≥ 50% reduction) with statin therapy remains suboptimal after an acute coronary syndrome (ACS). This study aimed to assess the level of lipid-lowering therapy (LLT) utilization and achievement of LDL-C targets after ACS hospitalization in the United Arab Emirates (UAE).

Methods

A retrospective, observational, longitudinal database analysis of Emirati patients with ACS or stable coronary heart disease was evaluated from January 2015 to June 2018. Patients were divided based on whether or not they were treated with LLT at index hospitalization with ACS. LDL-C target level achievement was assessed according to the 2013 American College of Cardiology/American Heart Association and European Society of Cardiology/European Atherosclerosis Society guidelines.

Results

A total of 3,066 patients (mean age 65.5 ± 14 years) met the inclusion criteria. Overall, 58.1% (n = 1782) of the patients in the cohort were on LLT during the ACS hospitalization. At discharge, the mean LDL-C level was 84.8 ± 39.0 mg/dl, and 28%, 21%, and 9% received high-, moderate-, and low-intensity statins, respectively. At 6 months (n = 2046; 66.7%), 27.7% and 16.7% achieved an LDL-C of <70 mg/dl and 70-100 mg/dl, respectively. The highest level of LDL-C reduction by 50% within 6 months was observed among patients using moderate-intensity statin (37.2%).

Conclusion

A large proportion of Emirati patients were not on LLT after ACS, and the rate of LDL-C target value attainment was extremely poor (27.7%). Optimal statin utilization by closely implementing the guidelines in the UAE is recommended.
