Atrial fibrillation is a predictor of nonobstructive coronary artery disease in elective angiography in old age: a cross-sectional study in Poland and Russia.

ABSTRACT:

Background

Significant changes in the coronary vessels are not confirmed in a large proportion of patients undergoing cardiac catheterization.

Aims

The present study aimed to determine correlates and independent predictors of nonobstructive coronary artery disease (CAD) in older adults referred for elective coronary angiography.

Methods

A cross-sectional study was conducted involving 2,214 patients referred to two medical centers (in Poland and Russia) between 2014 and 2016 for elective coronary angiography due to exacerbated angina, despite undergoing optimal therapy for CAD. The median age was 72 years (IQR: 68-76), and 49.5% patients were women.

Results

Significant stenosis (defined as stenosis of 50% or more of the diameter of the left main coronary artery
