Mortality at long-term follow-up of patients with no, nonobstructive, and revascularized 1-, 2-, and 3-vessel obstructive coronary artery disease

To investigate the 5-year survival of patients with coronary angiographic evidence of no coronary artery disease (CAD), nonobstructive CAD, and revascularized 1-vessel, 2-vessel, and 3-vessel obstructive CAD. Coronary angiography was performed in 2,057 unselected patients, mean age 69 years (57% men and 43% women), with an acute coronary syndrome (50%) or anginal chest pain.(50%). Of 2,057 patients, 760 (37%) had obstructive CAD with >50% obstruction of at least 1 major coronary artery (left anterior descending, left circumflex, and right coronary) and were revascularized, 695 (34%) had nonobstructive CAD (
