Recurrent Myocardial Infarction: Risk factors, neuropsychological status and prognostic implications in Omani patients admitted at Sultan Qaboos University Hospital (SQUH)

Survivors of a first acute myocardial infarction (MI) have increased risk for further cardiovascular events, including recurrent MI and death. Recurrent MI is common after a first MI and is associated with increased morbidity and mortality. Predictors and prognosis of a recurrent MI with contemporary management have not well been published around the world and Oman is no exception. The frequency of recurrent MI is 25-29%. Having a recurrent MI significantly worsens the course of the disease and its prognosis, causing a cascade of complications including heart failure (HF), arrhythmias, neuropsychological functioning, and the resultant decreased quality of life. Certain clinical and neuropsychological characteristics have the potential to identify a subset of MI which, in turn, might shed light on high risk for recurrent MI. We have limited data on the prevalence, clinical characteristics including risk factors and outcomes of patients with recurrent MI in our community practice in Oman. Therefore, this study aims to fill the gap in the literature and compare the impact of traditional and non-traditional risk factors in patients admitted to SQUH with recurrent MI versus single MI events.
