Abstract
Most studies reported that treating ST-Elevation Myocardial Infarction (STEMI) patients with high doses of rosuvastatin or atorvastatin could improve left ventricular remodeling and cardiac function. The current study compared the impact of high doses of rosuvastatin and atorvastatin on hypertrophy, fibrosis markers, serum inflammatory markers, and left ventricular function in STEMI patients after primary percutaneous coronary intervention (PCI). After primary PCI, eighty STEMI patients were randomized to receive either 20 mg of rosuvastatin (n = 40) or 40 mg of atorvastatin (n = 40) once daily for 3 months. Soluble Suppression of Tumorigenicity-2 (sST2), Matrix Metalloproteinase-9 (MMP9), C-Reactive Protein (CRP), lipid parameters, liver enzymes, and echocardiographic parameters were assessed for the two groups at baseline and after 3 months. After 3 months of treatment, a statistically significant reduction was observed in the rosuvastatin group regarding the levels of CRP (16 ± 6 vs. 20 ± 10 mg/L, P = 0.024) and MMP9 (104 ± 33 vs. 130 ± 42 ng/L, P = 0.003) compared with the atorvastatin group. The median percentage decrease in sST2 level in the rosuvastatin group was higher (6.1%) than in the atorvastatin group (2.3%) after 3 months of treatment. Also, in the rosuvastatin group, LVEF was significantly increased (48.5 ± 9 vs. 43.5 ± 11%, P = 0.029), while LVEDV and LVESV were significantly decreased compared to those of the atorvastatin group (101 [81/135] vs. 134 [100/150] ml, P = 0.041) (53 [37/75] vs. 73 [52/92] ml, P = 0.033), respectively. High-intensity rosuvastatin was superior to high-intensity atorvastatin in reducing the inflammatory response and myocardial fibrosis, thus improving ventricular remodeling and cardiac function better in STEMI patients. This randomized controlled trial was registered on October 11, 2022, on ClinicalTrials.gov under registration number: NCT05895123 "retrospectively registered".
