Effect of type of ST segment elevation in acute anterior MI on left ventricular function.
Pak Heart J Jan ;52(1):10-3.

Objective: To see the correlation between acute ST segment anterior wall myocardial infarction on ECG and LV function on echocardiography. Methodology: This cross-secitonal study was conducted on 1st January to 31 Mar 2017 in the Cardiology Department of Jinnah Hospital Lahore. ECG pattern were categorized into three grades of changes. In grade 1 there were only hyperacute T waves(concave type), in grade 2 there were hyper acute T waves and ST segment elevation(straight type) and in grade 3 there was tombstone appearanc eon ECG with the changes involving T waves and ST segment and QRS complex(convex type). We had assumed that there was maximum damage in grade 3, which was assessed on echocardiography. Patients with the diagnosis of anterior wall myocardial infarction who presented within 12 hours of presenting complaints and were thrombolysed by streptokinase were included. Results: About 50 patients with acute anterior wall MI were included in the study.Majority of the patients were between the 46 to 60 years, while 34% were below 45 years and 16% were above 65 years with mean of 52.66+10.87 years. Males were 88%. There were 20 patients who were falling in the category 1 with the mean EF 48.25+ 8.926%, while 11 patients in grade 2 had mean EF 35.45-+6.502% and 19 patients were in grade 3 who had maximum decrease in EF with mean of 31.05+7.375%. Conclusion: In patients who presented with acute anterior MI and were reperfused with SK, left ventricular function was preserved or there was less damage in grade 1, intermediate damage in grade 2 and maximum damage ingrade 3. This simple classification is useful for the prediction of left ventricular function at discharge.
