Abstract

Background: The optimal approach for a significant unprotected left main coronary stenosis is debated in light of the recent progresses of percutaneous coronary intervention. However, bypass surgery is still considered the first choice treatment. Randomized trials comparing percutaneous intervention and bypass grafting are ongoing, yet patient selection will limit their applicability. We designed a prospective multicentre registry, which will include patients with unprotected left main disease independent of the subsequent medical, interventional or surgical treatment. OBJECTIVE: The aim of this study is to evaluate prospectively the prevalence, treatment, and prognosis of patients with unprotected left main stenosis. STUDY DESIGN: More than 30 Italian care centres will participate. Patients with unprotected left main stenosis will be enrolled, excluding those with only mild atherosclerotic irregularities or patent grafts. The primary endpoint will be the 12-month occurrence of major adverse cardiac and cerebral events (MACCE, i.e. the composite of death, non-fatal myocardial infarction, stroke, or coronary revascularization by percutaneous intervention or bypass surgery). Secondary endpoints will be the occurrence of individual components of the primary endpoint at 1, 6, 24, and 60 months, the rate of major adverse cardiac and cerebral events without stroke, functional class, and quality of life. Analyses will be stratified according to lesion severity, as well as other patient, lesion, and procedural characteristics. EXPECTED RESULTS AND IMPLICATIONS: This multicentre prospective registry of patients with unprotected left main coronary stenosis treated medically, percutaneously or surgically will provide important and updated data on the prevalence, therapeutic choices, and prognosis of this important patient population.
