Angina Frequency After Acute Myocardial Infarction In Patients Without Obstructive Coronary Artery Disease.

ABSTRACT:

Background

Myocardial infarction (MI) patients without obstructive coronary artery disease (CAD) are at increased risk for recurrent ischemic events, but angina frequency post-MI has not been described.

Methods and results

Among MI patients who underwent angiography, we assessed angina at baseline, 1, 6, and 12 months using the Seattle Angina Questionnaire (SAQ). A hierarchical repeated measures modified Poisson model assessed the association between the absence of obstructive CAD (defined as epicardial stenoses >70% or left main >50%) and angina. Among 5539 MI patients from 31 US hospitals (mean age 60, 68% male), 6.9% had no angiographic obstructive CAD. More patients without obstructive CAD (vs. obstructive CAD) were female (57% vs 30%), non-white (51% vs 24%) and had NST
