The patients after myocardial infarction with ST elevation (STEMI) are endangered by the development inception of autonomic dysfunction, decreased baroreflex sensitivity, decreased heart rate variability, and increased blood pressure variability as a result of increased sympathetic activity and/or decreased parasympathetic activity. Thanks to direct angioplasty and optimal pharmacotherapy of coronary artery disease and heart failure, we didn't found any significant changes of these parameters within a one-year follow-up, and mortality due to cardiac etiology was very low in this group. Autonomic dysfunction and negative left ventricular remodeling is related only to a small group of patients after STEMI, whose risk stratification will be difficult.

Keywords: myocardial infarction with ST elevation; baroreflex sensitivity; autonomic dysfunction
