Abstract

Objective: To measure and compare HRV between acute anterior wall STelevation MI and inferior wall ST elevation MI.

Methodology: This cross sectional study was conducted at Department ofCardiology, Bahawal Victoria Hospital Bahawalpur, from 14th October 2016 to13th April 2017. Patients were divided into 2 groups consisting of anterior wallmyocardial infarction and inferior wall myocardial infarction having age 30-60years after thrombolytic therapy. Heart rate variability was measured by predischarge24 Holter monitoring using time domain method and Holter data wasanalyzed by MT 200 ECG V204 software. Quantitative variables like age, heartrate variability indices were presented as mean+1SD. T-test was used tocompare means and Chi Square test is applied to compare the frequencies. P≤0.05 was considered as significant.

Results: A total of 100 patients were included in the study with 50 in anterior wallMI group and 50 in inferior wall MI group. The mean age in this study was 48.21± 8.93 years. Males were predominant than females with 87% and 13%respectively. The mean SDNN, SDANN and SDNN index were 79.38±24.57ms,53.67±16.03 ms and 50.19±22.18 ms respectively. No significant differencefound regarding risk factor, and HRV indices (SDNN, SDANN and SDNN index)except in smoking in gender. When comparison was made within anterior wallmyocardial infarction and inferior wall myocardial infarction and two ages groupsthen again neither in risk factors nor in HRV indices showed significant difference.

Conclusion: No significant difference was found in heart variability indicesamong the patients of anterior wall MI versus inferior wall MI.

Key Words: Anterior wall myocardial infarction, Inferior wall myocardialinfarction, Heart rate variability.
