Comparing low dose rosuvastatin with ezetimibe to high dose rosuvastatin in heart attack patients

A Prospective, Multicenter, Randomized, Open-label Trial to Compare Low-dose ROSUvastatin Plus eZETimibe Versus High-dose Rosuvastatin in Patients With Acute Myocardial Infarction Undergoing Percutaneous Coronary Intervention

PHASE4 · The Catholic University of Korea · NCT04499859

This study is testing if a lower dose of rosuvastatin combined with ezetimibe can lower cholesterol and reduce heart problems just as well as a higher dose of rosuvastatin in heart attack patients.

What this trial studies

This clinical trial investigates the effectiveness of a combination therapy using low dose rosuvastatin (5mg) and ezetimibe (10mg) compared to high dose rosuvastatin (20mg) in patients who have experienced an acute myocardial infarction and undergone percutaneous coronary intervention. The goal is to determine if the combination therapy can achieve similar reductions in LDL cholesterol levels and decrease major adverse cardiac events. The study builds on previous findings that link LDL cholesterol reduction to heart disease risk, aiming to provide a potentially safer alternative to high-dose statin therapy.

Who should consider this trial

Good fit: Ideal candidates include adults aged 19 and older who have been diagnosed with myocardial infarction and treated with percutaneous coronary intervention.

Not a fit: Patients with life-threatening conditions, chronic liver disease, or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a safer and equally effective treatment option for patients recovering from a heart attack.

How similar studies have performed: Previous studies have shown promising results with similar combination therapies, but this specific approach is still being evaluated for its efficacy.
