Abstract:
Background: Of particular interest are the studies researching the correlations of myocardial bridges with hypertrophic cardiomyopathy and correlations
of thick myocardial bridges with the development of coronary atherosclerosis in the proximal to the bridge arterial part.
Material and methods: Assessment of the correlation between myocardial bridges, coronary atherosclerosis, and the degree of hypertrophy of the left
ventricle was performed by retrospective analysis of 6168 coronary angiography protocols (2012-2019) and echocardiographic data from patients’
clinical records.
Results: Moderate systolic compression predominated, and the number of patients detected with severe under the bridge systolic coronary stenosis was
double as in patients with nonsignificant coronary atherosclerosis. From the total number, patients with myocardial hypertrophy and myocardial bridges
were twice less when compared with the patients with the normal myocardial thickness. The comparative research did not show any interdependence
between the degree of vascular compression and the degree of left ventricular myocardial hypertrophy. Proximal to the bridges atherosclerosis was
detected in 32% of cases without correlation with the force of the myocardial bridge.
Conclusions: The study showed the absence of the correlation between the degree of arterial stenosis caused by the bridge and the degree of hypertrophy
of the ventricular myocardium as well as the degree of proximal to the bridge atherosclerosis. Important finding was that the degree of coronary systolic
compression is higher in patients with moderate and severe proximal to the bridge atherosclerosis.
