Relation Between Diastolic Perfusion Time and Coronary Artery Stenosis During Stress-Induced Myocardial Ischemia

Abstract

Despite differences in associated hemodynamic responses to various stress tests, a close relation exists between stenosis severity and diastolic perfusion time at the onset of stress-induced myocardial ischemia. Therefore, diastolic perfusion time at the ischemic threshold may be an indirect estimate of the hemodynamic significance of coronary stenosis.
