Acute Inferior Wall Myocardial Infarction

Objectives: To find the frequency of complete heart block in acute inferior wallmyocardial infarction and its relation with severe obstructive disease of the infarct related artery.Study Design: Cross sectional study. Setting: Department of Cardiology Choudhary PervaizElahi Institute of Cardiology, Multan. Period: June 2016 to June 2017. Methodology: Noneprobably consecutive sampling technique was used. Collected data was entered and analyzedthrough statistical/computer software SPSS vrs 22, mean ± SD was calculated for quantitativedata and variables like, age and frequency (percentage) was calculated for qualitative datalike gender, dominant artery and CHB. P value ≤ 0.05 was considered as significant. Results:A total number of n=234 (100%) patients were included in this study, both male and femalegenders. Distribution of Gender showed that male patients were more than females patientsi.e. n=198 (84.6%) and n=36 (15.4%) respectively. The main outcome variable of this studywas severity of disease. It was observed that, in with CHB group, severity of disease noted as93.2% (n=109) patients while in without CHB group it was 57.3% (n=67). Conclusion: Inferiorwall MI has severe adverse effects when combines with complete AV nodal heart block. Severityof disease was significantly associated with gender. Almost all times infarct related artery wasdominant right coronary artery.
