Prognostic value of adenosine stress echocardiography in chronic coronary syndromes with preserved left ventricular ejection fraction.

ABSTRACT:

Background

The prognostic value of functional echocardiographic parameters for risk stratification in chronic coronary syndrome (CCS) remains incompletely understood. This study aimed to integrate resting and stress echocardiographic parameters to identify sensitive non-invasive predictors of major adverse cardiovascular events (MACEs).

Methods

A total of 754 CCS patients with a resting left ventricular ejection fraction (LVEF) ≥ 50% undergoing adenosine stress echocardiography were prospectively enrolled. Parameters including myocardial perfusion, coronary flow velocity reserve (CFVR), and myocardial work were assessed. Resting and stress values were compared within groups, while dynamic changes were analyzed between CFVR-normal and impaired subgroups. Cox regression was us
