Background The frequency of residual angina and its impact on health status and death following anatomic complete revascularization in symptomatic patients with chronic coronary disease are unknown. Methods Data were analyzed from ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) trial participants randomized to invasive management with baseline angina (Seattle Angina Questionnaire Angina Frequency score 40%) following anatomic complete revascularization for chronic coronary disease and is associated with reduced quality of life and greater antianginal medication use but no increase in death. Registration Unique Identifier: NCT01471522.
