Clinical profile of patients having myocardial bridge on coronary angiography at tertiary care hospital in Rajasthan

Abstract

ABSTRACT Introduction: Myocardial bridge (MB) is usually defined as the segment of the coronary artery (epicardial) which passes intramurally. In the early days, it was not having any clinical importance, but later studies showed the presence of it in the left anterior descending (LAD) artery can be associated with myocardial infarction and cardiac death suddenly. Material and Methods: The aim of this study was mostly to assess the profile of patients with the MB on coronary angiography and to evaluate its association with atherosclerotic disease in the coronary artery at a tertiary care hospital in Rajasthan. In this study, evaluation was done (retrospectively) of the angiographic reports of the patients, and the prevalence of MB was seen totally, individually, or in combination with LAD, left circumflex, and right coronary artery. Results: Out of all 140 patients, 125 (89%) were males, and 15 (11%) were females. Among 140, the mean age of the patients having MB was 55.51 years. Out of 140 patients, 46% (65 patients) had diabetes, 41% (58 patients) had hypertension, and 42% (59 patients) were found to be smoker. Conclusion: The prevalence of MB in our study is similar to what is reported in the literature. The most common location of the MB was the mid-LAD segment.
