The unexpected silent manifestation of myocardial infarctions in ischemic heart failure patients: Insights from a case-control study.

Background: Recent studies show Silent Myocardial Infarction (SMI) as a quite frequent event. However, regarding severe tertiary care patients that frequently present consequences of Coronary Artery Disease (CAD) and Left Ventricular Dysfunction (LVD), the occurrence of this manifestation is unexpected and its associated factors aren't clear in the literature.

Aim: To compare clinical, laboratorial, ventricular and angiographic factors between silent and classical presentation of MI in patients with CAD and LVD.
