Abstract
Introduction: Smoking is an independent risk factor forischemic heart disease and acute myocardial infarction.Smoking raise both heart rate and blood pressure, thusincreasing myocardial oxygen demand, moreover it alsodecreases the dimension of coronary vessel and coronaryblood flow. Inferior wall Myocardial Infarction is consequenceof disease in usually Right coronary artery, whereas anteriorwall Myocardial Infarction is usually disease in left coronaryartery. The aim of the study is to evaluate whether smokinginfluence the incidence of inferior wall MI (Right coronaryartery). Study objective was to find out whether there was anassociation between smoking and inferior wall MyocardialInfarction and an early association of atherosclerosis andischemic heart disease with smoking.Material and methods: 126 patients of ST ElevationMyocardial Infarction admitted from the outdoor patientdepartment/ emergency department/ Cardiology OPD inMMIMSR, Mullana, Ambala, considered for study. Thosewho are willing to participate and fulfilling the inclusion andexclusion criteria.Result: In our study there was a high proportion of smokerin patient with inferior wall MI than other location of MI.Smokers were prone to get myocardial infarction at a youngerage as compared to others. Mortality was higher in anteriorwall MI as compared to Inferior wall MI. Anterior wall MIpresented with more complications i.e. cardiogenic shock andarrhythmias.Conclusion: Smoking enhance the risk of inferior wall MImore than other MI. Smoking thus appear to adversely affectthe Right coronary artery to greater extent than left coronaryarterial circulation by mechanism yet to be explored. Smokingleads to ischemic heart disease at early age.
