PROGNOSIS OF ACUTE INFERIOR WALL MI;
Introduction: Atrioventricular (AV) block is a common complication of acuteMyocardial Infarction (MI). In pre-thrombolytic era, high (second or third degree) AV blockwas seen in approximately 5-7% of patients presenting with acute MI. In setting of Inferior MI,this was even as high as 28%. Although, the advent of thrombolytic therapy has substantiallydecreased the mortality associated with acute MI, the incidence of AV block, particularly in thesetting of inferior MI, remains high. AV block in the setting of inferior MI is also associated withhigh in-hospital mortality, however, its effect on long-term mortality is uncertain. Objectives: Tocompare the in-hospital mortality of acute inferior wall myocardial infarction with and withoutcomplete Atrioventricular block. Settings: Department of Cardiology Faisalabad Institute ofCardiology, Faisalabad. Duration of Study: Six months From: 01-05-2014 to 30-11-2014. StudyDesign: Cohort study. Results: In our study, out of 80 cases(40 in each group) 42.5%(n=17)in Group-A and 37.5%(n=15) in Group-B were between 20-50 years of age while 57.5%(n=23)in Group-A and 62.5%(n=25) in Group-B were between 51-70 years of age, mean+sd wascalculated as 52.58+9.83 and 55.43+8.06 years respectively, 40%(n=16) in Group-A and47.5%(n=19) in Group-B were male while 60%(n=24) in Group-A and 52.5%(n=21) inGroup-B were females, comparison of in-hospital mortality in both groups was done showing32.5%(n=13) in Group-A and 7.5%(n=3) while 67.5%(n=27) in Group-A and 92.5%(n=37) hadno findings of in-hospital mortality, Relative Risk was calculated as 4.33 while P value:0.005.Conclusion: We concluded that in-hospital mortality is significantly high in acute inferior wallmyocardial infarction complicated by atrioventricular block.
