BACKGROUND AND OBJECTIVES: Limited data are available highlighting the different clinical aspects of acute coronary syndrome (ACS) patients, especially in Gulf countries. In this study, we aimed to compare patients who presented with acute myocardial infarction (AMI) as the first presentation of patients who have a history of ACS in terms of initial presentation, medical history, laboratory findings, and overall mortality.
METHODS: We used the Second Gulf Registry of Acute Coronary Events (Gulf RACE-II), which is a multinational observational study of 7930 ACS patients.
RESULTS: Among all patients, 4723 (59.6%) patients presented with AMI. First presentation AMI patients were older (mean age, 55 years vs. 53 years; p < 0.001) and had lower risk factors than patients with a history of ACS. Higher laboratory readings of cardiac markers and all aspects of mortality were significantly higher among patients with first presentation AMI. After adjustments for baseline variables, congestive heart failure [odds ratio (OR) = 1.08; 95% confidence interval (CI), 0.73-1.57], reinfarction (OR = 1.16; 95% CI, 0.58-2.30), cardiogenic shock (OR = 1.51; 95% CI, 0.74-3.08), stroke (OR = 2.30; 95% CI, 0.29-17.99), and overall mortality (OR = 1.16; 95% CI = 0.74-1.83) were independent predictive factors for first presentation AMI.
CONCLUSIONS: First presentation AMI patients tend to be older and to have lower rates of risk factors. Adverse clinical outcomes such as congestive heart failure, reinfarction, cardiogenic shock, and stroke were higher among patients with first presentation AMI compared to patients with a history of ACS.
