Abstract
BACKGROUND: As the elderly represent a substantial proportion of medical care beneficiaries, and there is limited data about age disparity in emerging countries, this study sought to investigate the impact of age on the management in patients with non-ST elevation acute coronary syndromes (NSTE-ACS). RESULTS: Two hundred patients with NSTE-ACS enrolled prospectively, patients' data, pharmacotherapy, management strategy as well timing to catheterization were documented. Patients grouped into ≥ 65 years versus < 65 years; 32.5% were ≥ 65-year-old. The older group presented as high GRACE risk (Global Registry of Acute Coronary Events) (67.7% versus 15.6%). Elderly patients were less likely to be referred for catheterization compared with younger counterparts (55.4% versus 76.3%, p = 0.003). Within low risk class patients, none of the elderly versus 9.33% of younger patients were catheterized within 2 h; in the same line, none of the elderly versus 16% of younger patients were catheterized within 24 h. Alternatively, at high risk class, 6.81% of the elderly and none of the younger patients were catheterized within 2 h. On the univariate analysis of variables to predict invasive strategy, presence of history of prior IHD, diabetes, absent in-hospital acute heart failure or atrial fibrillation/flutter, higher haemoglobin and lower creatinine levels predicted the use of invasive strategy, while on multivariate analysis, acute heart failure (95% CI - 0.38 to - 0.41, p = 0.01), lower haemoglobin (95% CI 0.002-0.07, p = 0.03), and atrial fibrillation/flutter (95% CI - 0.48 to - 0.02, p = 0.03) predicted conservative strategy. The elderly were more likely to have acute heart failure (32.3% versus 14.8%, p = 0.004), same as stroke (3.1% versus none, p = 0.04). CONCLUSIONS: Less-invasive strategy used in the elderly with NSTE-ACS compared with younger counterparts, yet age was not a predictor of catheterization underuse on multivariate analysis. It is crucial to bridge the age gap in the healthcare system in setting of ACS management by grasping the attention of decision makers and emphasizing on the adherence of healthcare providers to the guidelines to improve cardiovascular care and outcomes.
