Prevalence and clinical characteristics of mental stress-induced myocardial ischemia in patients with coronary heart disease.

ABSTRACT:

Objectives

The goal of this study was to evaluate the prevalence and clinical characteristics of mental stress-induced myocardial ischemia.

Background

Mental stress-induced myocardial ischemia is prevalent and a risk factor for poor prognosis in patients with coronary heart disease, but past studies mainly studied patients with exercise-induced myocardial ischemia.

Methods

Eligible patients with clinically stable coronary heart disease, regardless of exercise stress testing status, underwent a battery of 3 mental stress tests followed by a treadmill test. Stress-induced ischemia, assessed by echocardiography and electrocardiography, was defined as: 1) development or worsening of regional wall motion abnormality; 2) left ventricular ejection fraction reduction ≥ 8%; an
