Approach to the clinical profile of patients with intramyocardial coronary bridges.
CONCEPT OF STUDY
Two years retrospective study on coronariangiography with a selection of patients, of our department, with myocardial bridges and no atherosclerotic lesions.
MATERIAL AND METHODS
Out of 1620 patients, 26 cases had a suspected ischemic cardiopathy defined on the grounds of clinical, electrocardiographic, ergometric and coronariangiographic criteria.
From the 1620 cases, 26 (1.6%) presented intramyocardial coronary pathes. All situated on the left anterior descendant artery. 10 of these cases showed left ventricular hypertrophy, a change which is frequently associated with myocardial bridges. There was no correlation between the severity of systolic coronary constriction and clinical data.
The incidence of myocardial bridges in our group is different from other studies. The localization at the level of the left anterior descendant artery was the most frequent one. The findings in this study demonstrate a possible association between the intramyocardial coronary pathes and the left ventricular hypertrophy.
