Chen X, et al. - Researchers examined a large “real world” cohort of elderly patients with acute coronary syndrome (ACS) to evaluate the effect of percutaneous coronary intervention (PCI) on short and long-term survivals. This study included a total of 491 ACS patients. Both overall and a propensity score-matched cohort were examined to determine the impact of PCI on short and long-term survival. Findings demonstrated an association of PCI-treatment with improved 1- and 3-year survival in elderly ACS patients. They also found a different prognostic profile of PCI-treated vs those without PCI treatment. Age, heart rate, estimated glomerular filtration rate, malignancy, prior coronary artery bypass grafting, medication with statin were identified as independent predictors of 3-year all-cause mortality in PCI group, while age, heart rate, hypertension, and using of angiotensin converting enzyme inhibitor/angiotensin receptor antagonist were independent predictors of 3-year all-cause mortality in the non-PCI group.
