Heart Rate Turbulence According to Infarct Localization in ST Elevation MI Patients Who Underwent Primary Percutaneous Coronary Intervention
Abstract
Objective: To evaluate heart rate turbulence parameters in ST elevation myocardial infarction (MI) patients according to localization of infarction and infarct related artery. Material and
Material and Method: A total of 96 patients who underwent primary percutaneous coronary intervention were included in this study. They were grouped into two according to localization of infarction. Patients with atrial fibrillation, prior MI or coronary artery bypass, only posterior or lateral localization infarct or systemic inflammatory diseases were excluded. Transthoracic echocardiography was performed and 24- hour holter record was taken before discharge for all the participants. Heart rate turbulence parameters were calculated using Schmidt's critearias.
Results: Turbulence slope levels were at normal range in all study population and the difference was not statistically significant between groups (p= 0.483); turbulence onset levels were abnormal in 21 patients; 15 of them were in anterior group and it was significantly lower in inferior infarction group than anteriors (p= 0.005). When circumflex artery is the infarct related artery in anterior myocardial infarction patients; the difference was significant and p value was 0.007.
Conclusion: Heart rate turbulence; not turbulence slope but turbulence onset may be a risk determinator after myocardial infarction at early period and infarct related artery may play a role in this decision.
