title: [Myocardial bridging of the left anterior descending coronary artery and dobutamine-induced left ventricular outflow tract gradient -- a case report].
abstract: We present a case of a 47-year-old patient with arterial hypertension and progressive ST segment changes with a T wave inversion during 2 years of observation. Coronary angiography showed myocardial bridging of LAD and no significant coronary artery stenosis. During subsequent two last years the patient was repeatedly hospitalised due to chest pain. During the last hospitalisation a dobutamine stress testing was performed which provoked an increased left ventricular outflow tract gradient. This finding may be attributed to an early phase of hypertrophic cardiomyopathy, or dobutamine specific phenomenon.
