Primary Prevention With Statin and Incidence of Recurrent Myocardial Infarction and Cardiogenic Shock in Post-Acute Coronary Syndrome Patients

Adult patients (≥ 18 years of age) with acute coronary syndrome which are diagnosed under ICD-10 coding of I24.9 were included in this study. The inclusion criteria are patients with primary diagnosis of I24.9 and with a complete record of prior medical and treatment history, electrocardiographic findings, cardiac marker results and outcomes. Participants were grouped into 2 groups - statin and non-statin based on prior history of statin use prior to ACS. Diagnosis of ACS was made based on clinical, electrocardiographic and cardiac marker findings found in the medical record.

Data such as age, sex, ethnic, education, prior medical and treatment history, electrocardiographic and cardiac enzyme results as well as outcomes were collected from the patients' medical records. Outcomes of interest were defined as either recurrent myocardial infarction, cardiogenic shock, mortality or combinations of them as diagnosed in the medical records. GRACE and TIMI Scores are calculated to predict in hospital and future mortality rates.
