Comparing the Effect of a Preprocedural Loading Dose of Atorvastatin vs. Rosuvastatin on the Prevalence of No-reflow and Low TIMI Flow in Patients with ST-Elevation Myocardial Infarction Undergoing Primary Percutaneous Intervention

Background: As a promising revascularization therapy, percutaneous coronary intervention (PCI) is widely used in patients with coronary artery disease. No-reflow and low thrombolysis in myocardial infarction (TIMI) flow are two adverse periprocedural events. Objectives: This study aimed to compare the effectiveness of atorvastatin and rosuvastatin in reducing the no-reflow phenomenon in patients undergoing primary PCI. Methods: Following a randomized control design, 280 eligible patients with no history of MI or ischemic heart disease (IHD) with ST-elevation myocardial infarction (STEMI) who were candidates for coronary angioplasty underwent angioplasty from May 2020 to December 2020. Results: Our results showed that TIMI flow III was significantly higher in the rosuvastatin group, while the no-reflow was not seen in this group (P 0.001). Also, ST resolution after 90 minutes of PCI was significantly better in the rosuvastatin group. Conclusions: This study demonstrated that using a loading dose of rosuvastatin could reduce the no-reflow phenomenon in patients undergoing primary PCI.
