Vasospasm and myocardial bridge.
Two cases are discussed where vasospasm was induced at the level of myocardial bridges in patients with a recent myocardial infarction. A review of the clinical significance of myocardial bridges is presented. It is hypothesized that myocardial bridges may predispose to vasospasm; therefore, testing for vasospasm in patients with otherwise normal coronary angiograms is suggested.
