Effects of High-Dose Rosuvastatin on Ventricular Remodelling and Cardiac Function in ST-Segment Elevation Myocardial Infarction.

To investigate the effects of high-dose rosuvastatin on ventricular remodelling and cardiac function in ST-segment elevation myocardial infarction (STEMI). From January 2017 to March 2019, the clinical data of 93 patients with STEMI were collected and analysed, with 46 cases in the conventional-dose group (rosuvastatin, 10 mg/d) and 47 cases in the high-dose group (rosuvastatin, 20 mg/d). Blood lipid (TC, TG, LDL-C and HDL-C), serum inflammatory markers (hs-CRP, IL-6, TNF-α and ICAM-1), ventricular remodelling markers (NT-pro BNP, MMP-9, TIMP-4 and Gal-3) and indicators of cardiac function (LVESD, LVESD, LVESV, LVEDV, IVST and LVEF) were collected from all patients at the time of admission and 8 weeks after rosuvastatin treatment. After treatment with rosuvastatin for 8 weeks, compared with those in conventional-dose group, the levels of TC, TG, LDL-C, hs-CRP, IL-6, TNF-α, ICAM-1, NT-pro BNP, MMP-9 and Gal-3 in the high-dose group decreased significantly (P<0.05), while the increase of HDL-C and TIMP-4 levels was more obvious (P<0.05) than that in the conventional-dose group. Moreover, LVEF was significantly higher (P<0.05) and LVESD, LVESD, LVESV, LVEDV and IVST were significantly lower (P< 0.05) after treatment than before treatment in both groups. The improvement of cardiac ultrasound results in the high-dose group was more significant than that in the conventional-dose group (P< 0.05). This study suggests that high-dose rosuvastatin was better than conventional-dose rosuvastatin for improving blood lipid metabolism, reducing the inflammatory response, and preventing and treating ventricular remodelling and myocardial fibrosis, indicating that high-dose rosuvastatin had stronger therapeutic effect on STEMI than conventional-dose rosuvastatin.

Comparative effects of high-dose atorvastatin versus moderate-dose rosuvastatin on lipid parameters, oxidized-LDL and inflammatory markers in ST elevation myocardial infarction.

The important role of oxidized low density lipoprotein (oxidized-LDL) in preclinic atherosclerosis and pathophysiology of acute coronary syndromes studies have reported. Oxidation of LDL activates many inflammatory and atherogenic pathways and plays a pivotal role in atherosclerosis. Our aim in this study is to compare the effects of 80 mg daily dose of atorvastatin and 20 mg daily dose of rosuvastatin on lipid profiles and the levels of oxidized-LDL and inflammatory markers in ST elevation myocardial infarction (STEMI). One hundred and twenty patients with STEMI were enrolled in this study. The patients were randomly assigned to receive atorvastatin (80 mg/day) or rosuvastatin (20 mg/day) by using a ratio of 1:1 after revascularization. The levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), LDL-C, apolipoprotein B and apolipoprotein A were compared between groups after 4-week therapy. The values of oxidized-LDL, tumor necrosis factor receptor 1 and 2, Interleukin-6 and hs-CRP were also compared between groups. The Student's t test was used to detect absolute and percent changes between groups, and p < 0.05 was considered as statistically significant for all tests. After treatment in both treatment groups LDL-C, oxidized-LDL, hs-CRP, tumor necrosis factor receptor 1 and 2, Interleukin-6 values significantly decreased according to baseline. The only difference was in HDL-C levels. HDL-C slightly decreased in atorvastatin group while it increased in the rosuvastatin group compared baseline (-1.4 ± 8.9 mg/dl vs 2.0 ± 9.4 mg/dl, p = 0.04). We reported that both statin treatment regiments have comparable effects on LDL-C, oxidized-LDL and inflammatory markers. Moreover, it was observed that rosuvastatin was more effective in terms of ability to increase HDL-C level. Based on these findings, 20 mg daily dose of rosuvastatin may be an alternative to 80 mg daily dose of atorvastatin in patients with acute coronary syndrome.
