脉血康胶囊联合瑞舒伐他汀对冠脉临界病变患者冠脉病变程度的影响

目的研究脉血康胶囊联合瑞舒伐他汀对冠脉临界病变患者钙库操纵性钙通道蛋白(SOCC)基质交联分子1(STIM1)、钙释放激活钙通道蛋白Orai1及瞬时受体电位通道1(TRPC1)蛋白水平和冠脉病变严重程度的影响。方法将2015年1月—2016年12月北京安贞医院经定量冠脉造影检查确诊冠脉临界病变(BCL)住院患者160例设为临界病变组(BCL组),150例无冠脉病变的受试者为对照组(简称CTR组)。BCL组随机分为常规治疗组(简称RTT组,80例)和联合治疗组(简称CBT组,80例)。RTT组给予生活方式改善、阿司匹林、AECI、β受体阻滞剂及瑞舒伐他汀10 mg等药物。CBT组在常规药物治疗基础上,每日加用瑞舒伐他汀15 mg和脉血康胶囊3.0 g,连续治疗12个月。检测血小板STIM1、Orai1、TRPC1、高敏C-反应蛋白(hs-CRP)水平及TC、LDL-C、HDL-C、TG浓度。评价BCL组平均狭窄程度(MPS)。结果BCL组130例受试者复查冠脉造影。与本组治疗前比较,治疗后CBT组和RTT组血小板STIM1、Orai1、TRPC1水平均降低(P<0.05);CBT组冠脉临界病变的MPS明显减低(59.74±9.72vs.38.92±13.84,P<0.05),RTT组MPS有所下降(58.96±8.67vs.55.43±10.03),但差异无统计学意义(P>0.05)。与RTT组比较,治疗后CBT组血小板STIM1、Orai1、TRPC1、TC、LDL-C、TG、和hs-CRP明显降低(P<0.05,P<0.01),且CBT组MPS差值大于RTT组(P<0.01)。结论脉血康胶囊3.0 g和瑞舒伐他汀15 mg每日联合应用可降低SOCC水平,其可能是冠脉临界病变治疗的优化选择。

Effect of 2-year treatment with low-dose rosuvastatin on intima-media thickness in hypercholesterolemic subjects with asymptomatic carotid artery disease

Objectives: Recent evidence indicates that rosuvastatin 40 mg may exert a beneficial effect in both carotid and coronary atherosclerosis progression. In particular, 2-year rosuvastatin treatment reduced the progression of carotid intima-media thickness (cIMT) in patients with low cardiovascular risk. However, despite the fact that in clinical practice lower doses of rosuvastatin are usually administered at this time, there are no clear data about its effect on cIMT. Thus, the aim of this study was to evaluate the effect of rosuvastatin 10 mg/day on cIMT over a 2-year follow-up.

Methods: Forty-five patients with hypercholesterolemia and asymptomatic carotid atherosclerosis on baseline carotid ultrasound investigation were treated with rosuvastatin 10 mg/day for 24 months. cIMT and lipid profile were assessed after 12 months and at the end of the study (24 months).

Results: After 24 months, the treatment showed a 35.67% reduction in low-density lipoprotein cholesterol concentration (171 vs 110 mg/dl; p < 0.001), a 32.27% reduction in total cholesterol (251 vs 170 mg/dl; p < 0.001), a 19.67% increase in high-density lipoprotein cholesterol concentration (49 vs 61 mg/dl; p < 0.001), and a 10% reduction in triglycerides (120 vs 108 mg/dl; p < 0.01). Rosuvastatin treatment was associated with a 26.6% reduction in left cIMT (1.20 vs 0.90 mm; p < 0.001) and a 22.2% reduction in right cIMT (1.22 vs 0.95 mm; p < 0.001).

Conclusion: Two-year treatment with rosuvastatin 10 mg/day in hypercholesterolemic adults with evidence of subclinical atherosclerosis establishes a significant reduction in cIMT and improves lipid and lipoprotein levels, with a good tolerability profile.     

Acute renal failure with the combined use of rosuvastatin and fenofibrate

Among the lipid-lowering drugs, the statins and fibrates are the most commonly used agents. Either class of drug is considered relatively safe. Though a variety of albeit uncommon adverse side effects have been observed with both classes, most of these therapeutic complications can be managed without discontinuation of the offending drug. Sometimes, especially in patients with extremely high cholesterol and/or triglyceride levels, a combination regimen is deemed necessary. However, the combined use of lipid-lowering drugs increases the incidence and severity of adverse events. In this article, we report an unusual case of acute renal failure (ARF) in a patient who had been prescribed both a statin (rosuvastatin) and a fibrate (fenofibrate).     

Total cholesterol content of erythrocyte membranes is associated with the severity of coronary artery disease and the therapeutic effect of rosuvastatin

Abstract

Introduction. Numerous studies suggest that total cholesterol content of erythrocyte membranes (CEM) might play a critical role in atherosclerotic plaque progression and instability. However, the exact role of CEM in atherosclerosis remains obscure. Our study was designed to investigate the association between CEM and the severity of coronary artery disease (CAD), and to assess the effect of rosuvastatin on CEM levels.

Methods. CEM levels were assessed in 136 participants, including acute coronary syndrome (ACS) (non-ST-segment elevation ACS (NSTEACS) and ST-segment elevation myocardial infarction (STEMI)), stable angina pectoris (SAP), and controls. The Gensini score was used to estimate the severity of CAD. Additionally, 54 patients with CAD were medicated with rosuvastatin, 5 or 10 mg once daily, and then checked at 6 months.

Results. The highest level of CEM was found in the STEMI group, followed by the NSTEACS, the SAP, and the control groups. Gensini score in group IV (CEM > 141.6 μg/mg) was markedly higher compared with group I (CEM ≤77.6 μg/mg). Gensini scores in group II (77.6 < CEM ≤111.1 μg/mg) and group III (111.1 < CEM ≤141.6 μg/mg) were also higher than in group I (all P < 0.001). Furthermore, a positive correlation was found between CEM levels and Gensini score (r = 0.714, P < 0.001). CEM levels were dose-dependently reduced by rosuvastatin therapy.

Conclusions. CEM levels are positively associated with the severity of CAD, meaning that CEM might contribute to the development of CAD. Importantly, rosuvastatin could decrease CEM levels in patients with CAD and might effectively help to attenuate the progression of CAD.
