Pattern of Arrhythmias in Patients of Acute ST Elevation Myocardial Infarction with Impaired Renal Function

Introduction: Acute MI is a common presentation of acute coronary syndrome. All acute MI are classified as ST elevation and Non-ST-elevation MI. Acute STEMI is defined by at least two of the followings in which typical ECG changes is a must and any one either typical chest pain of cardiac origin or significantly raised troponin I level. Despite tremendous advances in the primary and secondary prevention of coronary artery disease, ST-elevation myocardial infarction (STEMI) still occurs in vast numbers. 80 percent people, who are living in developing country, die from cardiovascular disease. Objective: The main objective of the study was to evaluate the pattern of arrhythmias in patients of acute ST elevation myocardial infarction with impaired renal function. Methods: Prospective observational study. 100 patients of STEMI diagnosed by clinical, biochemical and ECG criteria were included in the study. After getting serum creatinine level, eGFR was calculated and if it is <60ml/min then the patient was selected for the study. Patients were followed up to hospital stay to see the outcome. Data was analyzed by computer based software SPSS-20. Results: STEMI hypertension was found in 61%, smoker was 52%, dyslipidemia was present in 78%, DM was in 31%, sedentary life style was found in 23% patients obesity was common among 23% of total patients and family history of IHD was found in 24% of patients. Pattern of arrhythmias divided into two categories -Tachyarrhythmias and Brady arrhythmias. The results of the two categories mentioned in this article. From the present study it can be concluded that impaired renal function among MI patients has an adverse outcome. Early detection of renal impairment is necessary to avoid increased mortality and morbidity.
