The study evaluated the prognostic significance of non-invasive parameters related to ventricular-arterial coupling (VAC) in patients with left ventricular ejection fraction (LVEF) ≥40% after a myocardial infarction (MI).
Using echocardiography and arterial tonometry, researchers measured VAC parameters during rest and a handgrip test in 374 patients, tracking major adverse cardiovascular events (MACE) over a median of 32 months.
Results indicated that the PWV/GLS ratio was the most useful parameter for identifying high-risk patients for MACE after MI, suggesting it adds valuable information beyond traditional assessment methods.
The study examines the prognostic significance of myocardial work parameters in patients after experiencing an acute myocardial infarction (AMI).
A total of 244 patients were monitored for major cardiac events after receiving specialized care, with findings indicating that those who experienced events had worse overall heart function and were generally older.
Specifically, the global work efficiency (GWE) was identified as a crucial measure, with a GWE below 91% indicating a significantly increased risk for major events, making it a valuable tool for assessing post-AMI patient risk.
