The ASCOT-LLA and ALLHAT-LLT trials provide conflicting evidence of the efficacy of statins in decreasing cardiovascular (CV) morbidity and mortality in hypertensive patients. We performed a meta-analysis to compare the overall efficacy of statins in hypertensive and nonhypertensive patients enrolled in major randomized clinical trials. We systematically reviewed PubMed publications from 1985 onward for placebo-controlled randomized trials that examined the effect of statins on cardiac morbidity and mortality. Only trials that followed >or=1,000 patients for >or=2 years were included in the meta-analysis. Outcomes included cardiac or CV death, major coronary events, or major CV events. Pooled estimates of relative risk (RR) were calculated separately for hypertensive and nonhypertensive patients. The moderating effect of the percentage of hypertensive patients at baseline was tested using meta-regression. Besides the ASCOT-LLA and ALLHAT-LLT, 12 trials enrolling 69,984 patients met inclusion criteria. Overall, in these 12 trials, statin therapy decreased cardiac death by 24% (RR 0.76, 95% confidence interval [CI] 0.71 to 0.82). There was no evidence of difference in RR estimates for hypertensive (RR 0.78, 95% CI 0.72 to 0.84) and nonhypertensive (RR 0.76, 95% CI 0.72 to 0.80) patients. Similarly, meta-regression showed that the efficacy of statins was not moderated by the percentage of hypertensive patients at baseline (Q estimate 1.51, p=0.22). In conclusion, statin therapy effectively decreases CV morbidity and mortality to the same extent in hypertensive and nonhypertensive patients.

Dyslipidemia, a significant risk factor for cardiovascular disease (CVD), is marked by abnormal lipid levels, such as the elevated lowering of low-density lipoprotein cholesterol (LDL-C). Statins are the first-line treatment for LDL-C reduction. Pitavastatin (PIT) has shown potential in lowering LDL-C and improving high-density lipoprotein cholesterol (HDL-C).

Background: The prevalence of very high-risk atherosclerotic cardiovascular disease (ASCVD) is significant in China, with suboptimal rates of low-density lipoprotein cholesterol (LDL-C) compliance exacerbating plaque instability and causing a higher incidence of major adverse cardiac events (MACEs). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are effective in reducing LDL-C levels, increase the stability of vulnerable plaque, and influence the progression of atherosclerosis through multiple mechanisms as demonstrated in animal studies. However, there is currently a lack of evidence regarding the efficacy and safety of high-intensity statin therapy combined with PCSK9i in the secondary prevention of ASCVD in the Chinese population.

Introduction: The efficacy and safety of statins for secondary prevention in patients who have experienced a cardioembolic stroke are not well-defined. However, previous observational data reported hyperlipidemia as a risk factor for both ischemic and bleeding complications in patients with AF and previous stroke. Based on these premises, we conducted a sub-analysis of the RAF and RAF-NOAC studies to evaluate the efficacy and safety of statins in secondary prevention in patients with acute ischemic stroke and AF.

Familial hypercholesterolemia (FH) is a genetic disease, usually with onset during childhood, characterized by elevated blood LDL cholesterol levels and potentially associated with severe cardiovascular complications. Concerning mutated genes in FH, such as , a small subset of FH patients presents a homozygous genotype, resulting in homozygous FH (HoFH) disease with a generally aggressive phenotype. Besides statins, ezetimibe and PCSK9 inhibitors, lomitapide (an anti-ApoB therapy) was also approved in 2012-2013 as an adjunctive treatment for HoFH.

Metabolic alterations are commonly associated with various cancers and are recognized as contributing factors to cancer progression, invasion, and metastasis. Drug repurposing, a strategy in drug discovery, utilizes existing knowledge to recommend established drugs for new indications based on clinical data or biological evidence. This approach is considered a less risky alternative to traditional drug development.
