Circulating miR-30a-5p as a prognostic biomarker of left ventricular dysfunction after acute myocardial infarction.

Left ventricular (LV) dysfunction after acute myocardial infarction (AMI) is associated with an increased risk of heart failure (HF) development. Diverse microRNAs (miRNAs) have been shown to appear in the bloodstream following various cardiovascular events. The aim of this study was to identify prognostic miRNAs associated with LV dysfunction following AMI.

[From chest pain to cardioverter-defibrillator implantation--a case report].

A case of a 48-year-old male admitted to the hospital because of recurrent chest pain, is described. Further diagnostic tests did not confirm ischemia, but revealed the presence of arrhythmogenic right ventricular cardiomyopathy. During hospital stay, the patient developed syncopal episode due to ventricular tachycardia.
