Assessment of Myocardial Bridges: A Retrospective Study

Coronary angiographies performed between January 1993 and November 1995 at Gülhane Military Medical Academy Cardiology Department Catheterization Laboratory were asse'ssed retrospectively in order to determine the localization, incidence, clinical and laboratory findings of myocardial bridges (MB) which are anatomical variations. Of 2917 coronary angiographies, there were 31 (1.06%) patients with MB of whom 27 were male and 4 were female. In our study, myocardial bridges were predominantly seen in left anterior descending coronary artery (LAD) distally to the second diagonal artery. The most common associated cardiovascular risk factor was hypertension (32%) while atherosclerosis was most commoly located at LAD. Electrocardiogram at rest was normal in55% of the patients. It's concluded that MB should be kept in mind symptomatic patients with normal coronary angiograms.
