Acute myocardial infarction (AMI) is a multifactorial condition and a leading cause of morbidity and mortality worldwide. This study aimed to assess the distribution of clinical and demographic characteristics among AMI patients and compare these findings with data from the RO-STEMI program for the Romanian population. We performed a case-control analysis of 138 patients presenting with chest pain at the Emergency Department of “Dr. Carol Davila” Central Military Emergency University Hospital between November 2021 and April 2022. The AMI group (n = 69) included patients with STEMI-specific ECG changes and elevated cardiac biomarkers, while the control group (n = 69) was represented by patients with chest pain but normal ECG and biomarkers. Men with AMI were 8.66 years younger than women, exceeding the 6.51-year difference reported by RO-STEMI. Hypertension and dyslipidemia were strongly associated with AMI (OR = 8.20 and OR = 7.36, p < 0.0001). During the pandemic, early presentation (<6 h) decreased by 15%, while arrivals within 6–12 h increased by 19.02%. Primary percutaneous coronary intervention was performed in 81.16% of cases versus 12.94% previously. Killip class and reduced left ventricular ejection fraction correlated with mortality and hospitalization duration. These findings indicate significant changes in AMI onset age, treatment strategies, and presentation delays compared to pre-pandemic data.
