Abstract

ECHEVERRY, Eduardo J et al. Myocardial bridges as a cause of acute myocardial infarction Report of a series of eleven cases and literature review. Rev. Colomb. Cardiol. [online]. 2013, vol.20, n.4, pp.240-245. ISSN 0120-5633.

The myocardial bridges are a congenital condition, with a variable frequency. These have been considered from an anatomical variant up to the cause of ischemia, acute myocardial infarction and sudden death. The mechanisms involved are related to the systolic compression of the coronary artery, the delay in recovering its diameter during diastole and the alteration in the speed profile and the coronary flow. The diagnostic approach still considers coronary angiography, but a greater role of intravascular ultrasound and intracoronary Doppler is increasingly accepted. Drug therapy is the first choice, but in selected patients with refractory angina or medical therapy failure, percutaneous and / or surgical revascularization could be considered. We report a series of eleven patients with documented myocardial bridges as part of the diagnostic study in the context of an acute coronary syndrome (acute myocardial infarction without ST elevation), and discuss their relationship as causal agent and the available therapeutic options.

Keywords : coronary artery disease; acute myocardial infarction; coronary angiography; stents.
