Core Tip
Core tip: Depressed heart rate variability (HRV) is usually considered a negative long-term prognostic factor after an acute myocardial infarction (MI). Anyway, most of the supporting research was conducted before the era of immediate reperfusion by percutaneous coronary intervention. In our study, in MI patients treated by early reperfusion abnormal values of HRV are present in a low percentage of cases. Low HRV does not correlate with long term-prognosis, both in ST-elevation and non-ST-elevation MI patients. Abnormal HRV seems to have lost prognostic significance in the present era of primary percutaneous revascularization.
