Relative contributions of statin intensity, achieved low-density lipoprotein cholesterol level, and statin therapy duration to cardiovascular risk reduction in patients with type 2 diabetes: population based cohort study

Red Yeast Rice and Statin Therapy in Patients with Hypercholesterolemia and the Comorbidities: A Retrospective Cohort Study on Lipid-Lowering Effects and Cardiovascular Outcomes

Red yeast rice (RYR) is known for its lipid-lowering effects in patients with hypercholesterolemia; however, its comparative efficacy with statins and risk reduction remains uncertain. This retrospective study analyzed data from 337,104 patients with hyperlipidemia in the Chang Gung Research Database cohort, spanning from January 2016 to December 2021. Exclusion criteria were applied to ensure data completeness and compliance, including an age limit of [Formula: see text] years, absence of RYR or statin treatment, and a treatment duration of [Formula: see text] days. Propensity score matching was employed to minimize bias based on baseline factors, with one patient matching with four patients in the comparison group. The study encompassed a total of 5,984 adult hyperlipidemic patients, with 1,197 in the RYR group and 4,787 in the statin group. The patients were also stratified into statin ([Formula: see text]) or combined use ([Formula: see text]) groups for further comparison. Following one year of treatment, both the RYR and statin groups exhibited reductions in total cholesterol and triglyceride levels. Most biochemical parameters showed no significant differences, except for elevated glutamic oxaloacetic transaminase levels in the RYR group ([Formula: see text]) and increased glycohemoglobin levels in the statin group at the three-month mark ([Formula: see text]). In patients with comorbid diabetes, hypertension, kidney, or liver diseases, RYR and statins demonstrated comparable risks for emergency room (ER) visits, stroke, and myocardial infarction (MI). However, the combination of RYR and statins was associated with reduced stroke-related hospitalizations in patients with diabetes, hypertension, and kidney disease, as well as decreased MI-related hospitalizations in patients with hypertension and kidney disease (all [Formula: see text]). In conclusion, both RYR and statins effectively lower blood lipid levels and mitigate related complications. Combining these therapies may lead to fewer ER visits, reduced stroke frequency, and fewer MI hospitalizations in hypertensive and kidney disease patients, and they decreased all-cause mortality in the kidney disease population. Further research on combined therapy is warranted.

The vascular complications of diabetes: a review of their management, pathogenesis, and prevention

INTRODUCTION

This review highlights the pathogenesis of both microvascular and macrovascular complications of diabetes and how these mechanisms influence both the management and preventative strategies of these complications. The cumulative data shown in this review suggest hyperglycemic and blood pressure control remain central to this intricate process.

AREAS COVERED

We reviewed the literature including retrospective, prospective trials as well as meta-analysis, and post hoc analysis of randomized trials on microvascular andmacrovascular complications.

EXPERT OPINION

Further research is needed to explore the ideal intervention targets and preventative strategies needed to prevent macrovascular complications. Furthermore, as the data for trials looking at microvascular complications lengthen more long-term data will further elucidate the role that the duration of diabetes has on these complications. Additionally, trials looking to maximize hyperglycemic control with multiple agents in diabetes, such as metformin, SGL2isand GLP-1 receptor agonists are currently in process, which will have implications for rates of microvascular as well as macrovascular complications.

Association of Strict Versus Lenient Cholesterol Lowering with Cardiac Outcomes, Diabetes Progression and Complications, and Mortality in Patients with Diabetes Treated with Statins: Is Less More?

INTRODUCTION

Whereas some guidelines recommend statin use to achieve low-density lipoprotein cholesterol (LDL-C) goal < 70 mg/dL for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in patients at higher risk, others recommend against a target LDL-C level. Achieving a target level < 70 mg/dL commonly requires the use of high intensity statins, which has been associated with higher risk of diabetes progression. The objective of this study is to assess the association of strict (≤ 70 mg/dL) versus lenient (> 70 to100 mg/dL) LDL-C lowering on major adverse cardiovascular events (MACE), diabetes progression, diabetes microvascular complications, and total mortality in patients with diabetes.

METHODS

This was a retrospective propensity score (PS)-matched study from a national cohort of, predominantly male, veterans diagnosed with diabetes without prior cardiovascular disease (from fiscal years 2003-2015), who were initiated on a statin. We created PS to match strict (mean LDL-C during follow-up ≤ 70 mg/dL) versus lenient (mean LDL-C during follow up > 70-100 mg/dL) using 65 baseline characteristics including comorbidities, risk scores, medication classes usage, vital signs, and laboratory data. Outcomes included MACE, diabetes progression, microvascular diabetes complications, and total mortality.

RESULTS

From 80,110 eligible patients, we PS-matched 21,294 pairs of statin initiators with strict or lenient LDL-C lowering. The mean (SD) age was 64 (9.5) years and mean (SD) duration of follow-up was 6 (3) years. MACE was similar in the PS-matched groups [6.1% in strict versus 5.8% in lenient; odds ratio (OR): 1.06; 95% confidence interval (95% CI) 0.98-1.15, P = 0.17]. Diabetes progression was higher among the strict vs lenient group (66.7% in strict versus 64.1% in lenient; OR 1.12; 95% CI 1.08-1.17, P < 0.001). There was no difference in microvascular diabetes complications (22.3% in strict versus 21.9% in lenient; OR 1.02; 95% CI 0.98-1.07, P = 0.31) and no difference in total mortality (14.6% in strict versus 15% in lenient; OR 0.97; 95% CI 0.92-1.02, P = 0.20).

CONCLUSION

Strict compared with lenient lowering of LDL-C with statins in men with diabetes without preexisting ASCVD did not decrease the risk of MACE but was associated with an increased diabetes progression. Clinicians should monitor their patients for diabetes progression upon escalating statins to achieve LDL-C levels ≤ 70 mg/dL.

Risk Factors of Recurrent Stroke in Young and Middle-Aged Stroke Patients after Interventional Therapy

Objective

To explore the risk factors of recurrent stroke in young and middle-aged stroke patients after interventional therapy.

Methods

Retrospective analysis was conducted on the data of 300 young and middle-aged stroke patients treated in our hospital (February 2015–February 2017). All patients received interventional therapy. They were followed up continuously after the interventional therapy, with recurrent stroke as the only endpoint event, and those who did not have the endpoint events were followed up for 5 years. Then, the patients were divided into the occurrence group and the nonoccurrence group according to whether there was a stroke. The social demographic data and clinical examination data of all patients were collected to analyze the differences between the groups. Logistic regression analysis was performed on the factors with statistically significant differences to verify the factors affecting recurrent stroke in young and middle-aged stroke patients after interventional therapy.

Results

Among the 300 patients, 69 (23.0%) had recurrent stroke and 231 (77.0%) had no recurrent stroke. The occurrence group (n = 69) had 12 cases (17.4%) of massive cerebral infarction, 18 cases (26.1%) of cerebral watershed infarction, 5 cases (7.2%) of multiple cerebral infarction, 25 cases (36.2%) of lacunar infarction, and 9 cases (13.0%) of TIA. Notable differences were observed in age, drinking history, marital status, body weight, diastolic pressure, systolic pressure, fasting blood glucose, glycosylated hemoglobin, cholesterol, and fibrinogen between the occurrence group and the nonoccurrence group (P < 0.05). The binary logistic regression analysis showed that age, drinking history, diastolic pressure, fasting blood glucose, glycosylated hemoglobin, cholesterol, and fibrinogen were the influencing factors of recurrent stroke in young and middle-aged stroke patients after interventional therapy.

Conclusion

Blood glucose, blood lipid, blood pressure, age, and living habits have an impact on recurrent stroke in young and middle-aged patients after interventional therapy. Therefore, while strictly controlling blood glucose, blood lipid, and blood pressure, patients should improve their living habits and enhance the awareness of prevention after interventional therapy.
