Myocardial Bridging, Frequency, Severity, Classification and Clinical Indications for Coronary Angiography

Abstract

Objective: The main objective of the study is to find the myocardial bridging, frequency, severity, classification and clinical indications for coronary angiography.

Study Design: Retrospective cross-sectional study.

Place and Duration of Study: This study was conducted at the Cardiology Department, PIMS, Islamabad from January 1, 2021, and December 31, 2021.

Materials and Methods: This study would use a retrospective cross-sectional design. Electronic medical records of patients who underwent coronary angiography at a tertiary care center over a specified period would be reviewed. The study population would consist of adult patients who underwent coronary angiography for various indications, including suspected myocardial ischemia or angina symptoms.

Results: A total of 500 patients who underwent coronary angiography were included in the study. The mean age of the study population was 60 years, and 300 (60%) were male. Of the 500 patients, 50 (10%) had myocardial bridging. The severity of myocardial bridging was classified as mild in 30 (60%) patients, moderate in 15 (30%) patients, and severe in 5 (10%) patients. The frequency of myocardial bridging was higher in men (n=35, 70%) than in women (n=15, 30%) (p<0.001). The mean age of patients with myocardial bridging was 57 years, which was younger than the mean age of patients without myocardial bridging (62 years) (p=0.02).

Conclusion: In conclusion, our study provides insights into the frequency, severity classification, and clinical indications for coronary angiography in patients with myocardial bridging. Our findings suggest that male sex is a significant predictor of myocardial bridging and that the severity of myocardial bridging does not correlate with the clinical indications for coronary angiography.
