About this study
Official title: Comparison of Intensive Lipid-Lowering Therapy With a Statin-Ezetimibe Combination (Without Aspirin) vs. Statin Monotherapy (With Aspirin) In Asymptomatic Patient With Coronary Artery Calcification
A Multicenter, randomized trial comparing the efficacy and safety of intensive lipid-lowering therapy using a statin-ezetimibe combination without aspirin versus statin monotherapy with aspirin in asymptomatic patients with coronary artery calcification
Read the detailed description
Coronary artery calcification is a well-established marker of subclinical atherosclerosis that effectively identifies high-risk individuals for cardiovascular events, even in asymptomatic patients. However, the optimal intensity of preventive interventions-particularly regarding the balance between efficacy and safety-remains unclear in asymptomatic patients with significant coronary calcification.
While aspirin has traditionally been used for the primary prevention of cardiovascular events, recent evidence suggests that its routine use in asymptomatic individuals may carry greater bleeding risks than cardiovascular benefits. In contrast, intensive lipid-lowering therapy with statins and ezetimibe has proven effective in reducing LDL-C levels and preventing cardiovascular events by slowing atherosclerotic progression and stabilizing plaques.
This study aims to evaluate whether intensive lipid-lowering therapy using a statin-ezetimibe combination (without aspirin) is non-inferior to statin monotherapy (with aspirin) in reducing cardiovascular events among patients with significant coronary artery calcification. By comparing these two strategies, we seek to establish whether more aggressive lipid management might obviate the need for aspirin in these intermediate- to high-risk yet asymptomatic patients.

◦ Intervention Medications: Pitavastatin 2 mg and aspirin (Based on the clinician's judgment, the statin dosage may be increased to pitavastatin 4 mg depending on the LDL response, and if there are adverse effects associated with aspirin, it can be replaced with clopidogrel.)

Measured: 48months
Secondary outcomes (11)
Event rate of a all cause death
All-cause mortality was used instead of cardiac mortality to avoid potentially difficult adjudication of causes of death, especially given the relatively low expected mortality rate. In addition, the cause of death will be adjudicated as being due to cardiovascular causes, non-cardiovascular causes, or undetermined causes.
Measured: 48months
Event rate of a cardiovascular death
includes death resulting from an acute myocardial infarction (MI), sudden cardiac death, death due to heart failure (HF), death due to stroke, death due to cardiovascular (CV) procedures, death due to CV hemorrhage, and death due to other CV causes
Measured: 48months
Event rate of a spontaneous myocardial infarction
A spontaneous myocardial infarction related to atherosclerotic plaque rupture, ulceration, fissuring, erosion, or dissection, resulting in intraluminal thrombus in one or more of the coronary arteries
Measured: 48months
Event rate of a stroke
- Ischemic Stroke B. Hemorrhagic Stroke C. Undetermined Stroke
Measured: 48months
Event rate of a urgent coronary revascularization
- Elective:
- Urgent:
- Emergency:
- Salvage:
Measured: 48months
Event rate of a Resuscitated cardiac arrest
Measured: 48months
Event rate of a unstable angina related hospitalization
Measured: 48months
Event rate of a composite of hard outcomes (all cause death, myocardial infarction and ischemic stroke)
Measured: 48months
Event rate of a Clinically relevant bleeding (Bleeding Academic Research Consortium definition ≥ type 2)
Bleeding Academic Research Consortium definition ≥ type 2
Measured: 48months
Changes of Lipid profile
Measured: 48months
