Comparison of Clinical Presentation Related on Risk Factors in Older and Younger Patients with Acute Coronary Syndrome

Acute coronary syndromes (ACS) are the leading cause of death in older adults. Early recognition of symptoms suggestive of ACS by the emergency triage nurse can improve patient outcomes. The aim of this study was to determine risk factors associated with typical and atypical symptoms in older and younger patients with ACS. This prospective study was performed on 446 patients who admitted at the Emergency Department of Tehran Medical Affiliated Hospital. Patients were considered for participation if they had undergone treatment with diagnoses of ACS based on confirmed electrocardiography changes, cardiac enzyme (CPK-MB), and had ≥ 1 of a set of typical symptoms of ACS. Patients with a history of cerebrovascular accident, heart failure, congestive occlusive pulmonary diseases, pneumonia and pulmonary embolism are excluded. Patients distributed in older ( ≥ 65 years) and younger ( 0.05). Older or younger patients with a history of hypertension (OR 0.43, CI 0.25 - 0.73, P = 0.002,), smoking (OR 0.51, CI 0.30 - 0.89, P = 0.019) and obesity (OR 0.69, CI 0.51 - 0.10, P = 0.011) have less chance to experience typical symptoms of ACS. Understanding the typical symptoms of ACS and factors related that may help in the early detection and more appropriate medical treatments in patients with ACS.
