Objective: To determine the clinical outcome of patients admitted with acute anterior versus acute inferior wall myocardial infarction.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: The study was conducted in emergency departments and adult cardiology wards of Armed Forces Institute of Cardiology/National Institute of Heart Diseases, from Aug 2019 to Nov 2019.
Methodology: This study was conducted on 340 patients (208 patients with Anterior wall myocardial infarction and 132 patients with inferior wall MI who presented with Acute ST-Elevation MI) to emergency department of Armed Forces Institute of Cardiology/National Institute of Heart Disease during specified period. Outcome was calculated using Electrocardiogram, Two-dimensional transthoracic echocardiogram, Troponin-I, baseline investigations and coro angiography Data was entered and analyzed with SPSS-23.
Results: Mean age was 59.38 ± 12.91 years in each group. In clinical symptoms chest pain was highest n=255 (71.4%) followed by diaphoresis 55 (15.4%) and breathlessness 51 (14.3%). The most common complications in patients with inferior wall MI were brady arrhythmia 8 (2.3%) whereas left ventricular failure 41 (12.1%) was more prevalent in patients with anterior wall MI after TVCAD. The results of cardiogenic shock 5 (1.5%),ventricular tachycardia 3 (0.8%) in inferior wall myocardial infarction were comparative to the results of cardiogenic shock 18 (5.3%) ventricular tachycardia 2 (0.5%) in anterior wall myocardial infarction. The number of stable patients was 91 (43.7%) in Anterior wall myocardial infarction and 51 (38.6%) in inferior wall MI.
Conclusion: The study shows the comparative clinical outcome of anterior wall myocardial infarction versus inferior wall myocardial infarction.
Persistent ST segment depression in precordial leads V5–V6 after Q-wave anterior wall myocardial infarction is associated with restrictive physiology of the left ventricle
