ABCDE Protocol in Stress Echocardiography

A for Asynergy

This is based on the presumable myocardial contractility alteration induced by stress in the presence of flow-limiting coronary stenosis. The substrate supply-demand imbalance leads to a reduction in myocardial radial thickening, a parameter sometimes limited by its semi-quantitative and subjective nature. Operator dependency can be minimized (but not eliminated) by specialized training and the adoption of conservative reading measures, as well as the accreditation and quality control of advanced echocardiography laboratories.

The regional motility assessment indicates that the higher the number of affected segments (universally defined), the worse the prognosis. This parameter is viewed as stenosis centered and has its value limited outside the epicardial coronary disease context.
