Habitual physical activity improves outcomes among patients with myocardial infarction

Purpose

This study evaluates the association between habitual physical activity (HPA) and the outcomes of patients with myocardial infarction (MI).

Methods

Patients newly diagnosed with MI were divided into two groups based on whether they engaged in HPA, defined as an aerobic activity with a duration of no less than 150 min/week, before the index admission. The primary outcomes included major adverse cardiovascular events (MACEs), cardiovascular (CV) mortality, and cardiac readmission rate 1 year following the index date of admission. A binary logistic regression model was applied to analyze whether HPA was independently associated with 1-year MACEs, 1-year CV mortality, and 1-year cardiac readmission rate.

Results

Among the 1,266 patients (mean age 63.4 years, 72% male), 571 (45%) engaged in HPA, and 695 (55%) did not engage in HPA before MI. Patients who participated in HPA were independently associated with a lower Killip class upon admission (OR = 0.48: 95% CI, 0.32-0.71, p < 0.001) and a lower prevalence of 1-year MACEs (OR = 0.74: 95% CI, 0.56-0.98, p = 0.038) and 1-year CV mortality (OR = 0.50: 95% CI, 0.28-0.88, p = 0.017) than those who did not participate in HPA. HPA was not associated with cardiac-related readmission (OR = 0.87: 95% CI, 0.64-1.17, p = 0.35).

Conclusions

HPA before MI was independently associated with a lower Killip class upon admission, 1-year MACEs, and 1-year CV mortality rate.

A practical guide to managing hypertension, hyperlipidemia, and hyperglycemia in patients with chronic myeloid leukemia

Tyrosine kinase inhibitors (TKIs) have significantly improved the prognosis of chronic myeloid leukemia (CML) since their approval. Although safe in general, TKIs carry concerns about cardiovascular adverse events. Hypertension, diabetes, and dyslipidemia are among the most common baseline comorbidities among CML patients. Guidelines for the management of the existing comorbidities or those related to TKI therapy are lacking. This paper will review hypertension, hyperglycemia and hyperlipidemia reported in CML patients or associated with TKI therapy and then propose a simple guide on their management.

Sociotechnical Intervention for Improved Delivery of Preventive Cardiovascular Care to Rural Communities: Participatory Design Approach

Background

Clinical practice guidelines recommend antiplatelet and statin therapies as well as blood pressure control and tobacco cessation for secondary prevention in patients with established atherosclerotic cardiovascular diseases (ASCVDs). However, these strategies for risk modification are underused, especially in rural communities. Moreover, resources to support the delivery of preventive care to rural patients are fewer than those for their urban counterparts. Transformative interventions for the delivery of tailored preventive cardiovascular care to rural patients are needed.

Objective

A multidisciplinary team developed a rural-specific, team-based model of care intervention assisted by clinical decision support (CDS) technology using participatory design in a sociotechnical conceptual framework. The model of care intervention included redesigned workflows and a novel CDS technology for the coordination and delivery of guideline recommendations by primary care teams in a rural clinic.

Methods

The design of the model of care intervention comprised 3 phases: problem identification, experimentation, and testing. Input from team members (n=35) required 150 hours, including observations of clinical encounters, provider workshops, and interviews with patients and health care professionals. The intervention was prototyped, iteratively refined, and tested with user feedback. In a 3-month pilot trial, 369 patients with ASCVDs were randomized into the control or intervention arm.

Results

New workflows and a novel CDS tool were created to identify patients with ASCVDs who had gaps in preventive care and assign the right care team member for delivery of tailored recommendations. During the pilot, the intervention prototype was iteratively refined and tested. The pilot demonstrated feasibility for successful implementation of the sociotechnical intervention as the proportion of patients who had encounters with advanced practice providers (nurse practitioners and physician assistants), pharmacists, or tobacco cessation coaches for the delivery of guideline recommendations in the intervention arm was greater than that in the control arm.

Conclusions

Participatory design and a sociotechnical conceptual framework enabled the development of a rural-specific, team-based model of care intervention assisted by CDS technology for the transformation of preventive health care delivery for ASCVDs.

Ponatinib for the treatment of adult patients with resistant or intolerant Chronic-Phase Chronic Myeloid Leukemia

INTRODUCTION

Patients with chronic myeloid leukemia in chronic phase (CP-CML) who are resistant or intolerant to second-generation tyrosine kinase inhibitors (TKIs) may benefit from treatment with a third-generation TKI, like ponatinib.

AREAS COVERED

In this review, the authors discuss the role of ponatinib, an oral pan-inhibitor of BCR-ABL1, with potent activity in heavily pretreated patients, including T315I mutation. In the long-term follow-up of the PACE trial, 60% of patients with prior TKIs exposure achieved a major cytogenetic response with ponatinib and 40% a major molecular response; 5-year overall survival was 73%. Cardiovascular adverse events represent the major toxicity associated with ponatinib. Adopting a dose-reduction approach appeared to be safe: starting with 45 or 30 mg and decreasing to 15 mg once BCR-ABL1/ABL1≤1% is achieved. In patients who are not candidates for ponatinib therapy, asciminib or other novel TKIs like HQP1351, represent alternative options.

EXPERT OPINION

In patients with CP-CML resistant or intolerant to second-generation TKIs, we favor using a third-generation TKI such as ponatinib. Although we initiate a donor search as soon as a patient fails a second-generation TKI, we still prefer treating patients with ponatinib and will only consider transplantation in the event of no response or disease progression.

Primary and Secondary Prevention of CAD: A Review

Coronary artery disease is the leading cause of death in both men and women, yet adequate control of risk factors can largely reduce the incidence and recurrence of cardiac events. In this review, we discuss various life style and pharmacological measures for both the primary and secondary prevention of coronary artery disease. With a clear understanding of management options, health care providers have an excellent opportunity to educate patients and ameliorate a significant burden of morbidity and mortality.

Understanding treatment-subgroup effect in primary and secondary prevention of cardiovascular disease: An exploration using meta-analyses of individual patient data

BACKGROUND AND OBJECTIVE

Recommendations for preventing cardiovascular (CV) disease are currently separated into primary and secondary prevention. We hypothesize that relative effects of interventions for CV prevention are not different across primary and secondary prevention cohorts. Our aim was to test for differences in relative effects on CV events in common preventive CV interventions across primary and secondary prevention cohorts.

METHODS AND RESULTS

A systematic search was performed to identify individual patient data (IPD) meta-analyses that included both primary and secondary prevention populations. Eligibility assessment, data extraction, and risk of bias assessment were conducted independently and in duplicate. We extracted relative risks (RR) with 95% confidence intervals (95% CI) of the interventions over patient-important outcomes and estimated the ratio of RR for primary and secondary prevention populations. We identified five eligible IPDs representing 524,570 participants. Quality assessment resulted in overall low-to-moderate methodological quality. We found no subgroup effect across prevention categories in any of the outcomes assessed.

CONCLUSION

In the absence of significant treatment-subgroup interactions between primary and secondary CV prevention cohorts for common preventive interventions, clinical practice guidelines could offer recommendations tailored to individual estimates of CV risk without regard to membership to primary and secondary prevention cohorts. This would require the development of reliable ASCVD risk estimators that apply across both cohorts.

Impact of pharmacist-led medication therapy management in ambulatory elderly patients with chronic diseases

AIMS

This study aimed to assess the impact of pharmacist-led medication therapy management (MTM) performed on ambulatory elderly patients with chronic diseases.

METHODS

Patients who came to a pharmacist-led outpatient clinic between January 2016 and June 2018 were enrolled in this study. Eligible subjects received MTM services from the pharmacists at least twice a year and the clinical data of these patients were complete. Drug-related problems (DRPs) and recommendations were evaluated using The Pharmaceutical Care Network Europe Classification for Drug related problems V8.03.

RESULTS

A total of 525 DRPs were identified during the study period. Treatment effectiveness (53.71%) was the most common DRP. The most frequently recommended intervention was changing the drug (48.76%). There were 92.38% patients accepting the interventions and 90.48% patients completely implemented. The number of drugs taken was the significant associated factor for DRPs. Postintervention data collection showed lower levels in systolic blood pressure (BP) and diastolic BP compared to the preintervention data collection. There were statistically significant changes in total cholesterol, low-density lipoprotein cholesterol and triglycerides between the pre- and postintervention data collections. The average cost of medications per patient for every month decreased from 387.72 to 355.17 renminbi (P = .009).

CONCLUSION

We confirmed that pharmacists had a valuable role to perform MTM services for ambulatory elderly patients, not only in identifying and solving the DRPs, but also in improving clinical outcomes (BP and lipid level) and cost-saving effect.

How to manage CML patients with comorbidities

Patients with chronic myeloid leukemia (CML) often have comorbidities, at an incidence that might be higher than in the general population. Because of the favorable outcome of most patients with CML treated with tyrosine kinase inhibitors (TKIs), a greater number of comorbidities might be the most significant adverse feature for long-term survival. The presence of comorbidities may also affect the risk of developing adverse events with TKIs. This effect is perhaps best exemplified by the risk of developing arterio-occlusive events, which is greatest for patients who have other risk factors for such events, with the risk increasing with higher numbers of comorbidities. The coexistence of comorbidities in patients with CML not only may affect TKI selection but also demands close monitoring of the overall health condition of the patient to optimize safety and provide the opportunity for an optimal outcome to such patients. With optimal, holistic management of leukemia and all other conditions afflicting them, patients with CML and comorbidities may aim for a near-normal life expectancy, just as the more select patients enrolled in clinical trials now enjoy.

Characterization of drug-related problems and associated factors in ambulatory patients in China

WHAT IS KNOWN AND OBJECTIVE

This study aimed to investigate the prevalence and the type of drug-related problems (DRPs) in ambulatory patients and identify factors that may be associated with risk of DRPs.

METHODS

Consecutive patients were enrolled from pharmacist outpatient clinics between January 2018 and June 2019. The pharmacists performed a comprehensive assessment of the patient's drug therapy. The DRPs and recommendations were evaluated using the DOCUMENT classification system.

RESULTS AND DISCUSSION

The study population consisted of 248 patients with a mean age of 72.55 ± 6.29. The patients had a mean of 7.55 ± 4.72 ongoing medications during patients' routine clinic visits. A total of 1188 DRPs were identified during the study period. An average of 4.79 DRPs per patient was detected. Sixty-two different traditional Chinese patent medicines (TCPMs) contributed to 102 DRPs. Drug selection (24.9%) was the most common DRP followed by under treated (24.2%) and monitoring needed (24.2%). The number of medications taken was the significant factor for DRPs. Pharmacists made 1092 recommendations to address the DRPs (an average 0.92 recommendations per DRP). A change in therapy was the most common recommendation (43.6%), followed by the category 'monitoring' (28.6%). The overall acceptance rate of clinical pharmacist recommendations was 88.7%. More than a half (51.6%) of all interventions were assigned a moderate level of clinical significance.

WHAT IS NEW AND CONCLUSION

Drug-related problems were commonly observed among ambulatory Chinese patients. Clinical pharmacists had a valuable role to play in identifying and solving the DRPs.

Collaborative cardiovascular management of patients with chronic myeloid leukemia on tyrosine kinase inhibitors

Tyrosine kinase inhibitors (TKIs) of the BCR-ABL fusion protein have dramatically changed the mortality of chronic myeloid leukemia (CML) but they carry a risk of serious vascular morbidity. While TKIs do not cure CML, daily oral administration of a TKI can control CML and TKIs are chronic medications. Interestingly, vascular complications can occur at any time a patient is on a TKI. Therefore, it is imperative that all care team members and patients are aware of and watching for possible vascular complications. In the following review, a case of arterial thrombosis secondary to the TKI ponatinib is presented as well as a discussion of thrombotic and vascular adverse events reported with TKIs. TKIs are metabolized through the cytochrome P450 system and important drug interactions to consider are reviewed. Finally, we present a multidisciplinary approach to the management of patients with CML on TKIs.

Strategies to Prevent Cardiotoxicity

OPINION STATEMENT

Cardiovascular disease is a leading cause of death among cancer survivors. While the field of cardiology as a whole is driven by evidence generated through robust clinical trials, data in cardio-oncology is limited to a relatively small number of prospective clinical trials with heterogeneous groups of cancer patients. In addition, many pharmaceutical trials in oncology are flawed from a cardiovascular perspective because they exclude patients with significant cardiovascular (CV) history and have wide variation in the definitions of CV events and cardiotoxicity. Ultimately, oncology trials often underrepresent the possibility of cardiovascular events in a "real world" population. Thus, the signal for CV toxicity from a cancer treatment is often not manifested until phase IV studies; where we are often caught trying to mitigate the CV effects rather than preventing them. Most of the data about cardiotoxicity from cancer therapy and cardioprotective strategies has been developed from our experience in using anthracyclines for over 50 years with dramatic improvement in cancer survivorship. However, as we are in an era where cancer drug discovery is moving at lightning pace with increasing survival rates, it is imperative to move beyond anthracyclines and commit to research on the cardiovascular side effects of all aspects of cancer therapy with a focus on prevention. We emphasize the role of pre-cancer treatment CV assessment to anticipate cardiac issues and ultimately optimizing CV risk prior to cancer therapy as an opportunity to mitigate cardiovascular risk from cancer therapy.

The Interplay of the Global Atherosclerotic Cardiovascular Disease Risk Scoring and Cardiorespiratory Fitness for the Prediction of All-Cause Mortality and Myocardial Infarction: The Henry Ford ExercIse Testing Project (The FIT Project)

Cardiorespiratory fitness (CRF) is inversely associated with atherosclerotic cardiovascular disease (ASCVD) risk. It is unclear whether the prognostic value of CRF differs by baseline estimated ASCVD risk. We studied a retrospective cohort of patients without known heart failure or myocardial infarction (MI) who underwent treadmill stress testing. CRF was measured by metabolic equivalents of task (METs) and ASCVD risk was calculated using the Pooled Cohorts Equations. Multivariable-adjusted Cox regressions analyses examined the association between METs and incident all-cause mortality and MI outcomes stratified by baseline ASCVD risk. The C-index evaluated risk discrimination while net reclassification improvement evaluated reclassification with CRF added to the ASCVD risk score. Our study population consisted of 57,999 patients of mean age 53 (13) years, 49% women, 64% white, 29% black. Over a median follow-up 11 years (interquartile range 8 to 14 years) there were 6,670 (11%) deaths, while there were 1,757 (3.0%) MIs over a median follow-up of 6 years (interquartile range 3 to 8 years). Among patients with ASCVD risk ≥20%, those with METs ≥12 had a 77% lower risk of all-cause mortality (Hazard ratio 0.23 95% confidence interval = 0.20, 0.27) and 67% lower risk of MI (Hazard ratio 0.33 95% confidence interval = 0.24, 0.46) compared to METs <6. Similar results were obtained for those with ASCVD risk <5%. Addition of METs to ASCVD risk score improved the C-statistic from 0.778 to 0.798 for all-cause mortality and 0.726 to 0.733 for MI (both p <0.001). Addition of METs to ASCVD risk score significantly reclassified risk of all-cause mortality (p <0.001) but not MI (p = 0.052). In conclusion, CRF is inversely associated with risk of all-cause mortality and MI at all levels of ASCVD risk, and provides incremental risk discrimination and reclassification beyond the ASCVD risk score.

Association between Q192R polymorphism in the PON1 gene and statin responses in cardiac patients

Introduction

Paraoxonases are a group of different forms enzymes that consist of three non-similar isoforms, PON1, PON2 and PON3, which are located near to each other on the long arm of chromosome7. This study aims to investigate the association of a Q192R polymorphism of PON1 gene and statin response in patients with ischemic heart disease with dyslipidemia.

Methods

The studied population included three hundred patients with coronary artery disease with dyslipidemia who were prescribed statins. Total lipid profile was measured in these patients both before and after approximately 6 months of treatment. Q192R polymorphism of PON1 gene was assessed by real-time PCR.

Results

There were no significant differences in baseline lipid levels according to different genotypes in all studied casesof Q192R (rs662) polymorphism. HDL-C goals were attained less often in patients with RR homozygosity than in Q allele carriers. Analysis by univariate logistic regression confirmed that QQ/QR carriers had an increased chance of attaining HDL-C goals.

Conclusion

This study shows that the Q192R polymorphism of PON1gene has important role in interindividual variety in accomplishment of HDL-C goals in response to statins.

•

The studied 300 patients with ischemic heart disease with dyslipidemia who were prescribed statins.

•

Q192R polymorphism of PON1 gene was assessed by real-time PCR.

•

This study shows that the Q192R polymorphism of PON1 gene may play a role in achievement of HDL-C goals in response to statins.

Drug-related problems among community-dwelling older adults in mainland China

Background Little is known about the extent of drug-related problems (DRPs) in community-dwelling older adult patients with chronic diseases in mainland China. Setting A medication therapy review service at a community health center in Chongqing, China. Objective To identify and categorize DRPs along with pharmacists' recommendations in addressing the DRPs identified. Method The study was conducted between May 2015 and July 2016. A total of 102 community-dwelling older adults were included. MTR was carried out by clinical pharmacists. DRPs and pharmacotherapy recommendations were recorded and analyzed. Main outcome measure The number of drug-related problems and main problem categories. Results The average age of patients was 69.4 years. Patients took an average of 6.3 medications. A total of 489 DRPs were identified (mean of 4.8 per patient). The most common category was under-treated (27.8%) followed by over- or under-dose (18.8%) and monitoring (17.8%). The number of medications taken was the significant associated factor for DRPs. Pharmacists made 526 recommendations to address the DRPs (mean of 1.1 recommendations per DRP). Primary care providers accepted 68.1% of these recommendations, and implemented 60.9% of them. Conclusion The prevalence of DRPs among studied patient population was high. Pharmacists may play a vital role in addressing the DRPs and optimize pharmacotherapy through MTR service located in community health centers.

Spotlight on ponatinib in the treatment of chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia: patient selection and perspectives

Ponatinib, a third-generation tyrosine kinase inhibitor that inhibits BCR/ABL independent of the mutation status, is currently approved for the treatment of patients with chronic myeloid leukemia or acute lymphoblastic leukemia that are either resistant or unable to tolerate another tyrosine kinase inhibitor. Its US Food and Drug Administration approval was based on results from long-term follow-up of the pivotal Phase II PACE trial, which demonstrated deep and durable molecular responses in the treated patients. Despite the remarkable responses, ponatinib has been associated with high frequency of severe vascular events, which led to its withdrawal from the market in 2013. Following analysis of the risk factors of patients who developed vascular side effects, ponatinib was reintroduced in the market 1 year later with specific dose-reduction recommendations and carrying a black box warning. Thus, careful patient selection with identification of patients whose potential benefit from ponatinib exceeds the potential risks associated with its use is crucial. Ongoing and future studies are focusing on earlier detection of mutations, strategies to minimize side effects, and potential expansion of the treatment indications. Clinical trials testing the safety and efficacy of ponatinib as frontline therapy are ongoing.

Vascular Erectile Dysfunction and Subclinical Cardiovascular Disease

PURPOSE OF REVIEW

We review the recent literature on the hypothesized temporal relationship between subclinical cardiovascular disease (CVD), vascular erectile dysfunction (ED), and clinical CVD. In addition, we combine emerging research with expert consensus guidelines such as The Princeton Consensus III to provide a preventive cardiologist's perspective toward an ideal approach to evaluating and managing CVD and ED risk in patients.

RECENT FINDINGS

Development of ED was found to occur during the progression from subclinical CVD to clinical CVD. A strong association was observed between subclinical CVD as assessed by coronary artery calcium (CAC) and carotid plaque and subsequent ED, providing evidence for the role of subclinical CVD in predicting ED. ED is also identified as a substantial independent risk factor for overt clinical CVD, and ED symptoms may precede CVD symptoms by 2-3 years.

SUMMARY

Given the body of evidence on the relationship between subclinical CVD, ED, and clinical CVD we recommend that all men with vascular ED should undergo cardiovascular risk assessment. We further recommend using CAC scores for advanced risk assessment in patients at low-intermediate to intermediate risk (5-20% CVD risk), with risk driving subsequent lifestyle and pharmacologic treatment decisions.

Beyond Anthracyclines: Preemptive Management of Cardiovascular Toxicity in the Era of Targeted Agents for Hematologic Malignancies

Advances in drug discovery have led to the use of effective targeted agents in the treatment of hematologic malignancies. Drugs such as proteasome inhibitors in multiple myeloma and tyrosine kinase inhibitors in chronic myeloid leukemia and non-Hodgkin lymphoma have changed the face of treatment of hematologic malignancies. There are several reports of cardiovascular adverse events related to these newer agents. Both "on-target" and "off-target" effects of these agents can cause organ-specific toxicity. The need for long-term administration for most of these agents requires continued monitoring of toxicity. Moreover, the patient population is older, often over 50 years of age, making them more susceptible to cardiovascular side effects. Additional factors such as prior exposure to anthracyclines often add to this toxicity. In light of their success and widespread use, it is important to recognize and manage the unique side effect profile of targeted agents used in hematologic malignancies. In this article, we review the current data for the incidence of cardiovascular side effects of targeted agents in hematologic malignancies and discuss a preemptive approach towards managing these toxicities.

Cell-based secondary prevention of childbirth-induced pelvic floor trauma

With advancing population age, pelvic-floor dysfunction (PFD) will affect an increasing number of women. Many of these women wish to maintain active lifestyles, indicating an urgent need for effective strategies to treat or, preferably, prevent the occurrence of PFD. Childbirth and pregnancy have both long been recognized as crucial contributing factors in the pathophysiology of PFD. Vaginal delivery of a child is a serious traumatic event, causing anatomical and functional changes in the pelvic floor. Similar changes to those experienced during childbirth can be found in symptomatic women, often many years after delivery. Thus, women with such PFD symptoms might have incompletely recovered from the trauma caused by vaginal delivery. This hypothesis creates the possibility that preventive measures can be initiated around the time of delivery. Secondary prevention has been shown to be beneficial in patients with many other chronic conditions. The current general consensus is that clinicians should aim to minimize the extent of damage during delivery, and aim to optimize healing processes after delivery, therefore preventing later dysfunction. A substantial amount of research investigating the potential of stem-cell injections as a therapeutic strategy for achieving this purpose is currently ongoing. Data from small animal models have demonstrated positive effects of mesenchymal stem-cell injections on the healing process following simulated vaginal birth injury.

Racial Differences in the Prognostic Value of Cardiorespiratory Fitness (Results from the Henry Ford Exercise Testing Project)

The aim of this analysis was to determine whether racial differences exist in the prognostic value of cardiorespiratory fitness (CRF) in black and white patients undergoing stress testing. We included 53,876 patients (mean age 53 ± 13, 49% women) from the Henry Ford Exercise Testing project free of established coronary disease or heart failure who completed a maximal exercise test from 1991 to 2009. Patients were followed for a mean duration of 11.5 years for all-cause mortality, ascertained by linkage with the Death Master File. Follow-up over mean 6.2 years was also available for incident myocardial infarction. Multivariate Cox proportional hazards regression models were used adjusting for demographic variables, risk factors, medications, and reason for stress test referral, including formal interaction testing by race (black vs white). Black patients (n = 16,725) were younger (54 ± 13 vs 52 ± 13, p <0.001) but had higher prevalence of hypertension (73% vs 57%, p <0.001) and obesity (28% vs 21%, p <0.001). On average, black patients achieved a lower CRF compared with whites (8.4 vs 9.5 metabolic equivalents, p <0.0001). A graded increase in mortality risk was noted with decreasing CRF for both black and white patients. In multivariate Cox regression, CRF was a predictor of both myocardial infarction and mortality, with no significant interaction between race, fitness, and outcomes (all interaction terms p >0.10). CRF is a strong predictor of all-cause mortality in both white and black patients, with no significant interaction observed between race, fitness, and outcomes.

Tyrosine Kinase Inhibitor-Associated Cardiovascular Toxicity in Chronic Myeloid Leukemia

For most patients with chronic myeloid leukemia, tyrosine kinase inhibitors (TKIs) have turned a fatal disease into a manageable chronic condition. Imatinib, the first BCR-ABL1 TKI granted regulatory approval, has been surpassed in terms of molecular responses by the second-generation TKIs nilotinib, dasatinib, and bosutinib. Recently, ponatinib was approved as the only TKI with activity against the T315I mutation. Although all TKIs are associated with nonhematologic adverse events (AEs), experience with imatinib suggested that toxicities are typically manageable and apparent early during drug development. Recent reports of cardiovascular AEs with nilotinib and particularly ponatinib and of pulmonary arterial hypertension with dasatinib have raised concerns about long-term sequelae of drugs that may be administered for decades. Here, we review what is currently known about the cardiovascular toxicities of BCR-ABL1 TKIs, discuss potential mechanisms underlying cardiovascular AEs, and elucidate discrepancies between the reporting of such AEs between oncology and cardiovascular trials. Whenever possible, we provide practical recommendations, but we concede that cause-directed interventions will require better mechanistic understanding. We suggest that chronic myeloid leukemia heralds a fundamental shift in oncology toward effective but mostly noncurative long-term therapies. Realizing the full potential of these treatments will require a proactive rational approach to minimize long-term cardiovascular and cardiometabolic toxicities.

Impact on cognitive function-are all statins the same?

Dementia is a major public health concern, affecting an estimated 7% of the population over 65 and 30% over 80 years of age. There is mounting evidence in the literature from meta-analyses of high-quality prospective cohort studies that statins may have a positive impact in reducing the incidence of dementia. Little is known, however, on whether certain types of statins are more impactful than others. This narrative review specifically explores the various properties of different statin types and whether these differences lead to a clinically significant differential impact on cognitive function. We critically evaluate the literature, emphasizing interesting and important new findings, and overall aim to bring the reader up-to-date on evidence-based recommendations.

Assessment of American Heart Association's Ideal Cardiovascular Health Metrics Among Employees of a Large Healthcare Organization: The Baptist Health South Florida Employee Study

BACKGROUND

Healthcare organizations and their employees are critical role models for healthy living in their communities. The American Heart Association (AHA) 2020 impact goal provides a national framework that can be used to track the success of employee wellness programs with a focus on improving cardiovascular (CV) health. This study aimed to assess the CV health of the employees of Baptist Health South Florida (BHSF), a large nonprofit healthcare organization.

HYPOTHESIS

HRAs and wellness examinations can be used to measure the cardiovascular health status of an employee population.

METHODS

The AHA's 7 CV health metrics (diet, physical activity, smoking, body mass index, blood pressure, total cholesterol, and blood glucose) categorized as ideal, intermediate, or poor were estimated among employees of BHSF participating voluntarily in an annual health risk assessment (HRA) and wellness fair. Age and gender differences were analyzed using χ(2) test.

RESULTS

The sample consisted of 9364 employees who participated in the 2014 annual HRA and wellness fair (mean age [standard deviation], 43 [12] years, 74% women). Sixty (1%) individuals met the AHA's definition of ideal CV health. Women were more likely than men to meet the ideal criteria for more than 5 CV health metrics. The proportion of participants meeting the ideal criteria for more than 5 CV health metrics decreased with age.

CONCLUSIONS

A combination of HRAs and wellness examinations can provide useful insights into the cardiovascular health status of an employee population. Future tracking of the CV health metrics will provide critical feedback on the impact of system wide wellness efforts as well as identifying proactive programs to assist in making substantial progress toward the AHA 2020 Impact Goal.

PON1 polymorphisms are predictors of ability to attain HDL-C goals in statin-treated patients

OBJECTIVES

PON1 plays an important role in inhibiting LDL-C oxidation, which reduces atherosclerosis and cardiovascular disease. Elevated PON1 activity or levels may contribute to increased HDL-C levels, but controversy exists over the hypothesis that genetic variation in the PON1 gene locus modulates HDL-C levels and responses to statin treatment. Therefore, the objective of this study was to investigate the association between two polymorphisms in the PON1 gene and statin responses in a south Brazilian population.

DESIGN AND METHODS

The study population included 433 dyslipidemic patients who were prescribed statins. Total cholesterol, triglyceride, HDL-C and LDL-C levels were measured in these patients both before and after approximately 6months of treatment with simvastatin/atorvastatin. Genotypes were assessed by real-time PCR for two PON1 polymorphisms, Q192R (rs662) and L55M (rs854560).

RESULTS

Baseline lipid levels were not associated with Q192R or L55M polymorphisms. For the Q192R (rs662) polymorphism, we observed that HDL-C goals were attained less often in patients with RR homozygosity than in Q allele carriers (χ(2) P=0.009, adjusted residual analysis P=0.003). For the L55M (rs854560) polymorphism, LL homozygotes were underrepresented among subjects that achieved the HDL-C goal (χ(2) P=0.026, adjusted residual analysis P=0.008). Analysis by univariate logistic regression confirmed that QQ/QR and MM/ML carriers had an increased chance of attaining HDL-C goals (OR=2.41, CI95%=1.32-4.40, P=0.004 and OR=1.68, CI95%=1.15-2.45, P=0.008). In a multivariate logistic analysis used to assess predictors of attaining an HDL-C goal>1.55mmol/L, we observed that gender (OR=1.71, CI95%=1.04-2.83, P=0.036), baseline HDL-C levels (OR=1.13, CI95%=1.10-1.16, P<0.001) and the QQ/QR+MM/ML genotypes increased the chance of achieving HDL-C goals (OR=2.81, CI95%=1.35-5.85, P=0.006).

CONCLUSIONS

The results of this study show that the Q192R (rs662) and L55M (rs854560) polymorphisms may play a role in interindividual variation in achievement of HDL-C goals in response to statins.

A Randomized Double-blind Controlled Trial of Lactobacillus acidophilus Plus Bifidobacterium bifidum versus Placebo in Patients with Hypercholesterolemia

BACKGROUND

Hypercholesterolemia is a major risk factor for cardiovascular disease. Not all patients respond well to traditional cholesterol lowering medications. Probiotics have been evaluated for their cholesterol-lowering effects in humans with variable results. This study was performed to evaluate the efficacy of two probiotics in lowering the serum cholesterol of hypercholesterolemic patients.

MATERIALS AND METHODS

A randomized double-blind controlled trial was conducted comparing placebo to Lactobacillus acidophilus plus Bifidobacterium bifidum in patients diagnosed with hypercholesterolemia. Placebo or probiotic capsules were taken three times daily for six weeks. Pre- and post-treatment total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C) and triglyceride (TG) levels and demographic parameters of the two groups were compared. From a total of 70 participants, 64 completed the assigned treatment (31 in probiotics group and 33 in the control group).The two treatment groups were matched for age, sex, weight, height, BMI, waist and hip circumferences, and blood pressure.

RESULTS

Baseline evaluation revealed no difference between the probiotics group and control group levels of TC, HDL-C, LDL-C and TG. TC levels in the probiotics group decreased during treatment (237.2 vs. 212.7 mg/dL, p<0.05). TC and LDL-C levels in the control group increased significantly from their baseline levels during treatment. TC (212.7 vs 252.8 mg/dL, p<0.001), HDL-C (52.0 vs 59.1 mg/dL, p=0.04) and LDL-C (153.9 vs 182.1 mg/dL, p<0.01) levels in the probiotics group were significantly lower at the end of treatment than the corresponding levels in the control group.

CONCLUSION

A combination of Lactobacillus acidophilus and Bifidobacterium bifidum decreased serum total cholesterol, LDL-cholesterol and HDL-cholesterol levels in hypercholesterolemic patients over a six week period. There was no effect on serum triglyceride or fasting blood glucose levels.

Prehypertension--prevalence, health risks, and management strategies

Prehypertension (blood pressure 120-139/80-89 mmHg) affects ~25-50% of adults worldwide, and increases the risk of incident hypertension. The relative risk of incident hypertension declines by ~20% with intensive lifestyle intervention, and by 34-66% with single antihypertensive medications. To prevent one case of incident hypertension in adults with prehypertension and a 50% 5-year risk of hypertension, 10 individuals would need to receive intensive lifestyle intervention, and four to six patients would need to be treated with antihypertensive medication. The relative risk of incident cardiovascular disease (CVD) is greater with 'stage 2' (130-139/85-89 mmHg) than 'stage 1' (120-129/80-84 mmHg) prehypertension; only stage 2 prehypertension increases cardiovascular mortality. Among individuals with prehypertension, the 10-year absolute CVD risk for middle-aged adults without diabetes mellitus or CVD is ~10%, and ~40% for middle-aged and older individuals with either or both comorbidities. Antihypertensive medications reduce the relative risk of CVD and death by ~15% in secondary-prevention studies of prehypertension. Data on primary prevention of CVD with pharmacotherapy in prehypertension are lacking. Risk-stratified, patient-centred, comparative-effectiveness research is needed in prehypertension to inform an acceptable, safe, and effective balance of lifestyle and medication interventions to prevent incident hypertension and CVD.

Aspirin overutilization for the primary prevention of cardiovascular disease

Background

Aspirin is commonly used for the primary prevention of cardiovascular disease (CVD) in the US. Previous research has observed significant levels of inappropriate aspirin use for primary CVD prevention in some European populations, but the degree to which aspirin is overutilized in the US remains unknown. This study examined the association between regular aspirin use and demographic/clinical factors in a population-based sample of adults without a clinical indication for aspirin for primary prevention.

Methods

A cross-sectional analysis was performed using 2010–2012 data from individuals aged 30–79 years in the Marshfield Epidemiologic Study Area (WI, USA). Regular aspirin users included those who took aspirin at least every other day.

Results

There were 16,922 individuals who were not clinically indicated for aspirin therapy for primary CVD prevention. Of these, 19% were regular aspirin users. In the final adjusted model, participants who were older, male, lived in northern Wisconsin, had more frequent medical visits, and had greater body mass index had significantly higher odds of regular aspirin use (P<0.001 for all). Race/ethnicity, health insurance, smoking, blood pressure, and lipid levels had negligible influence on aspirin use. A sensitivity analysis found a significant interaction between age and number of medical visits, indicating progressively more aspirin use in older age groups who visited their provider frequently.

Conclusion

There was evidence of aspirin overutilization in this US population without CVD. Older age and more frequent provider visits were the strongest predictors of inappropriate aspirin use. Obesity was the only significant clinical factor, suggesting misalignment between perceived aspirin benefits and cardiovascular risks in this subgroup of patients. Prospective studies that examine cardiac and bleeding events associated with regular aspirin use among obese samples (without CVD) are needed to refine clinical guidelines in this area.

Dietary intake and adherence to the 2010 Dietary Guidelines for Americans among individuals with chronic spinal cord injury: a pilot study

OBJECTIVE

To investigate dietary intake and adherence to the 2010 Dietary Guidelines for Americans in individuals with chronic spinal cord injury (SCI) and able-bodied individuals.

DESIGN

A pilot study of dietary intake among a sample of individuals with SCI >1 year ago from a single site compared with able-bodied individuals.

PARTICIPANTS/METHODS

One hundred black or white adults aged 38-55 years old with SCI >1 year and 100 age-, sex-, and race-matched adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Dietary intake was assessed by the CARDIA dietary history. Linear regression analysis was used to compare dietary intake between the subjects with SCI and those enrolled in the CARDIA study. Further, adherence to the 2010 Dietary Guidelines for dairy, fruits, and vegetables, and whole-grain foods was assessed.

RESULTS

Compared with CARDIA participants, participants with SCI consumed fewer daily servings of dairy (2.10 vs. 5.0, P < 0.001), fruit (2.01 vs. 3.64, P = 0.002), and whole grain foods (1.20 vs. 2.44 P = 0.007). For each food group, fewer participants with SCI met the recommended servings compared with the CARDIA participants. Specifically, the participants with SCI and in CARDIA who met the guidelines were, respectively: dairy, 22% vs. 54% (P < 0.001), fruits and vegetables 39% vs. 70% (P = 0.001), and whole-grain foods 8% vs. 69.6% (P = 0.001).

CONCLUSIONS

Compared with able-bodied individuals, SCI participants consumed fewer daily servings of fruit, dairy, and whole grain foods than proposed by the 2010 Dietary Guideline recommendations. Nutrition education for this population may be warranted.

Identifying opportunities to improve aspirin utilization for the primary prevention of cardiovascular disease in a regional health care system

OBJECTIVE

Aspirin is an important part of primary cardiovascular disease prevention, but little is known about aspirin use patterns in regional health care systems. This study used electronic health records from Marshfield Clinic to identify demographic, geographic, and clinical predictors of aspirin utilization in central Wisconsin adults without cardiovascular disease.

METHODS

A cross-sectional design was employed using 2010-2012 data from patients in the Marshfield Epidemiologic Study Area. Individuals who took aspirin-containing medication daily or every other day were considered regular aspirin users. There were a total of 6678 adults in the target region who were clinically indicated for aspirin therapy for primary cardiovascular disease prevention, per national guidelines.

RESULTS

Aspirin was generally underutilized in this population, with 35% of all clinically indicated adults taking it regularly. Adjusted models found that individuals who were younger, female, not covered by health insurance, did not visit a medical provider regularly, smokers, were not obese, or did not have diabetes were least likely to take aspirin. In addition, there was some local variation in that aspirin use was less common in northeastern communities within the regional service area.

CONCLUSION

Several aspirin use disparities were identified in central Wisconsin adults without cardiovascular disease, with particularly low utilization observed in those without diabetes and/or without regular physician contact. Methods of using electronic health records to conduct primary care surveillance as outlined here can be adopted by other large health care systems in the state to optimize future cardiovascular disease prevention initiatives.

Rationale and design of the Henry Ford Exercise Testing Project (the FIT project)

Although physical fitness is a powerful prognostic marker in clinical medicine, most cardiovascular population-based studies do not have a direct measurement of cardiorespiratory fitness. In line with the call from the National Heart Lung and Blood Institute for innovative, low-cost, epidemiologic studies leveraging electronic medical record (EMR) data, we describe the rationale and design of the Henry Ford ExercIse Testing Project (The FIT Project). The FIT Project is unique in its combined use of directly measured clinical exercise data retrospective collection of medical history and medication treatment data at the time of the stress test, retrospective supplementation of supporting clinical data using the EMR and administrative databases and epidemiologic follow-up for cardiovascular events and total mortality via linkage with claims files and the death registry. The FIT Project population consists of 69 885 consecutive physician-referred patients (mean age, 54 ± 10 years; 54% males) who underwent Bruce protocol treadmill stress testing at Henry Ford Affiliated Hospitals between 1991 and 2009. Patients were followed for the primary outcomes of death, myocardial infarction, and need for coronary revascularization. The median estimated peak metabolic equivalent (MET) level was 10, with 17% of the patients having a severely reduced fitness level (METs < 6). At the end of the follow-up duration, 15.9%, 5.6%, and 6.7% of the patients suffered all-cause mortality, myocardial infarction, or revascularization procedures, respectively. The FIT Project is the largest study of physical fitness to date. With its use of modern electronic clinical epidemiologic techniques, it is poised to answer many clinically relevant questions related to exercise capacity and prognosis.

Improving lipid control following myocardial infarction

PURPOSE OF REVIEW

Following a myocardial infarction, lipid-lowering therapy is an established intervention to reduce the risk of recurrent cardiovascular events. Prior studies show a need to improve clinical practice in this area. Here, we review the latest research and perspectives on improving postmyocardial infarction lipid control.

RECENT FINDINGS

Dyslipidemia and myocardial infarction remain leading causes of global disability and premature mortality throughout the world. The processes of care in lipid control involve multiple patient-level, provider-level, and healthcare system-level factors. They can be challenging to coordinate. Recent studies show suboptimal use of early high-intensity statin therapy and overall lipid control following myocardial infarction. Encouragingly, lipid control has improved over the last decade. Implementation science has identified checklists as an effective tool. At the top of the checklist for reducing atherogenic lipids and recurrent event risk postmyocardial infarction is early high-intensity statin therapy. Smoking cessation and participation in cardiac rehabilitation are also priorities, as are lifestyle counseling, promotion of medication adherence, ongoing lipid surveillance, and medication management.

SUMMARY

Optimizing lipid control could further enhance clinical outcomes after myocardial infarction.

Usefulness of coronary and carotid imaging rather than traditional atherosclerotic risk factors to identify firefighters at increased risk for cardiovascular disease

Cardiovascular disease (CVD) accounts for 45% of deaths in on-duty firefighters, in contrast to 15% of all deaths occurring on conventional jobs. Therefore, with the goal of developing a tailored prevention program, we assessed CVD risk in a cohort of 50 firefighters using imaging and traditional risk factors. Participants were aged ≥40 years without a history of CVD or diabetes. CVD risk was assessed by way of history, physical examination, blood tests, risk scores, coronary artery calcium (CAC), and carotid intima-media thickness (cIMT). Median age was 46 years; 90% of subjects were men, 92% were white, and 30% were former smokers. Only 4% of subjects were hypertensive but 48% were prehypertensive. Only 14% of subjects had a normal body mass index; 38% were overweight, 48% were obese, and 46% had a high waist circumference. Based on fasting glucose ≥100 mg/dl or hemoglobin A1c ≥5.6%, 50% of subjects had prediabetes and 2% had diabetes. Median total cholesterol was 196 mg/dl; median high-sensitivity C-reactive protein was 1.0 mg/L. CAC was detected in 22% of subjects and carotid plaque was detected in 36%. Using standard reference databases, 54% of subjects had cIMT greater than the seventy-fifth percentile; 66% had carotid plaque and/or cIMT greater than the seventy-fifth percentile. Atherogenic lipoprotein markers and risk scores did not differ between firefighters who had subclinical atherosclerosis and those who did not. Traditional CVD risk assessment does not adequately identify at-risk firefighters. In contrast, CAC and cIMT were useful for identifying increased risk and implementing primary prevention. In conclusion, early detection and integration of imaging with traditional risk assessment will be important in preventing premature death and disability among firefighters.

[Nutritional counseling in community pharmacies within the framework of the French National Nutrition and Health Program]

INTRODUCTION

The French National Nutrition and Health Program (PNNS), nutrition policy whose objective is to improve the health status of the population, establishes dietary guidelines to answer priority nutritional objectives. The pharmacist, as the drug specialist, dispenses not only products but also services adapted to their patients' needs such as nutritional counseling in order to improve their quality of life. The purpose of this work was to develop nutritional tip sheets answering to the PNNS recommendations that could be exploited by pharmacists to advise their patients.

MATERIALS AND METHOD

Two types of tools were developed: self-test on nutrition, aiming at arousing the dialogue between patient and pharmacist on nutrition, and nutritional tip sheets raising the main advices to be dispensed according to the patients' profiles, with their scientific argumentation.

RESULTS

The implementation of this tool was tested in a pilot pharmacy, where the utility of nutritional tip sheets was assessed in 24 patients. Among the patients who answered (46 %, that is 11 respondents), 82 % (9 patients) considered that these tip sheets were useful to improve their lifestyle. Nutritional tip sheets answering the priority objectives of the PNNS and relatives to the main diseases were most frequently used.

DISCUSSION

It would be sensible to widen this nutritional tool to other pharmacies, especially for the most popular sheets. The implementation of a file listing these nutritional tip sheets could constitute an in-service training tool.

CONCLUSION

This nutritional device could contribute to therapeutic education provided by community pharmacists.
