Introduction: The myocardial bridge integrates one of the possible differential diagnosis of Coronary Artery Disease (CAD) as a result of usually having an asymptomatic progress, but it may present itself with angina pectoris and more rarely with myocardial infarction or even sudden death. Case report: A female patient, 57 years old, asymptomatic at the first clinical evaluation, without precordialgia, hypertensive, underwent a routine cardiopulmonary stress test (CPX), which revealed a ST depression, in CM5 of 1,5 mm in relation to repose.  Commentary: The study concluded that the clinical repercussions of Myocardial Bridging were due to the increment of tension during heart contraction in consequence of the increase of end diastolic pressure at the left ventricle due to arterial hypertension influence, what justifies the degree of myocardial hypertrophy.
