Abstract

We compared left ventricular (LV) remodeling following a first time acute anterior ST-elevation myocardial infarction (aSTEMI) treated with primary coronary intervention (pPCI) in different age groups. A total of 116 patients, 61 aged <65 and 55 aged ≥65 years, who survived after a recent aSTEMI treated with pPCI, underwent dobutamine stress-echocardiography (DSE) and non-invasive measurement of left anterior descending coronary artery flow reserve (CFR) during intravenous adenosine infusion. Baseline LV dimensions and systolic function were similar between the two groups; wall motion score indices during all DSE stages and CFR were also similar. In both groups, the LV ejection fraction was positively affected by the presence of viability in the necrosis area and by a higher CFR, but negatively influenced by viability in a remote area, an indirect sign of an extensive infarction size. This study demonstrates that PCI in the geriatric population with aSTEMI is as equally effective as in younger subjects, in terms of LV remodeling and function.
