The study aimed to assess how comorbidities impact the effectiveness of in-hospital revascularization in older patients with non-ST-segment elevation acute coronary syndrome (NSTEACS).
Researchers analyzed data from 7211 patients aged 70 and older, finding that revascularization significantly reduced 1-year mortality rates, although this benefit diminished as comorbidities increased.
Specifically, patients with renal failure, peripheral artery disease, and chronic pulmonary disease experienced fewer benefits from revascularization compared to those with fewer comorbidities, while diabetes and previous strokes did not significantly alter the results.
