Abstract
Background: Type 2 myocardial infarction (MI) is caused by myocardial ischemia resulting from an imbalance between oxygen supply and demand in the heart. This study aimed to assess the incidence, variations in clinical characteristics, current therapeutic approaches, and overall prognosis in patients with type 2 MI compared to those with type 1 MI.
Methods: This prospective, cross-sectional study involved 350 Egyptian patients presenting with MI. Participants were categorized into type 1 MI (n = 262) and type 2 MI (n = 88) groups based on standard diagnostic criteria. Data regarding demographic characteristics, clinical presentations, management strategies, and outcomes, including in-hospital, 30-day, and 6-month mortality rates; major adverse cardiovascular events (MACE); and hospitalization for heart failure, were collected and analyzed.
Results: Coronary angiography was performed more frequently in patients with type 2 MI than in those with type 1 MI. Primary percutaneous coronary intervention and coronary artery bypass grafting were more commonly performed in type 1 MI patients. A statistically significant difference was observed between type 1 MI and type 2 MI concerning echocardiographic findings and hospital stays. However, there was no significant difference in MACE at 1-month and 6-month follow-ups, except for mortality and stroke, where a statistically significant difference was found.
Conclusions: Type 1 MI is more common than type 2 MI. Nonetheless, type 2 MI is associated with higher mortality rates and longer hospital stays. Patients with type 1 MI typically present with chest pain, while those with type 2 MI predominantly present with dyspnea, syncope, and hemodynamic instability. Cardiac interventions are primarily performed in patients with type 1 MI.(Iranian Heart Journal 2024; 25(4): 51-58)
