摘要
高脂血症是心血管疾病的重要危险因素，降低血脂水平对预防心血管事件具有重要意义。本研究旨在探讨辛伐他汀对高脂血症患者血脂水平及心血管事件的影响，为临床治疗提供依据。研究采用随机双盲对照试验设计，纳入300例确诊为高脂血症的患者，分为辛伐他汀治疗组和安慰剂对照组，随访12个月。通过检测总胆固醇（TC）、低密度脂蛋白胆固醇（LDL-C）、高密度脂蛋白胆固醇（HDL-C）及甘油三酯（TG）水平，并记录心血管事件发生率，评估药物疗效与安全性。结果显示，辛伐他汀治疗组的TC、LDL-C和TG水平显著下降，HDL-C水平略有升高，且心血管事件发生率明显低于对照组（P0.05）。此外，未观察到严重不良反应。研究表明，辛伐他汀可有效改善高脂血症患者的血脂谱，显著降低心血管事件风险，其安全性和耐受性良好。本研究进一步验证了辛伐他汀在血脂管理中的重要作用，并强调个体化治疗策略的必要性，为优化高脂血症患者的长期管理提供了新思路。关键词：辛伐他汀；高脂血症；血脂水平；心血管事件；个体化治疗策略
Simvastatin's Impact on Lipid Profiles and Cardiovascular Events in Hyperlipidemic Patients
Abstract
Hyperlipidemia is a critical risk factor for cardiovascular diseases, and reducing lipid levels plays an essential role in preventing cardiovascular events. This study aimed to investigate the effects of simvastatin on lipid profiles and cardiovascular events in patients with hyperlipidemia, providing evidence for clinical treatment. A randomized double-blind controlled trial was conducted, enrolling 300 patients diagnosed with hyperlipidemia, who were divided into a simvastatin treatment group and a placebo control group, with a follow-up period of 12 months. Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG) levels were measured, and the incidence of cardiovascular events was recorded to evaluate the efficacy and safety of the drug. The results showed that TC, LDL-C, and TG levels significantly decreased in the simvastatin treatment group, while HDL-C levels slightly increased, and the incidence of cardiovascular events was markedly lower than in the control group (P0.05). Furthermore, no serious adverse reactions were observed. This study demonstrates that simvastatin effectively improves the lipid profile in hyperlipidemic patients and significantly reduces the risk of cardiovascular events, with good safety and tolerability. It further confirms the crucial role of simvastatin in lipid management and highlights the necessity of individualized treatment strategies, offering new insights for optimizing long-term management in patients with hyperlipidemia.
