Key result
Depressed heart rate variability recorded in the subacute phase of myocardial infarction did not correlate with long-term outcomes in patients treated with immediate coronary reperfusion.
Why the study?
Does depressed heart rate variability correlate with long-term prognosis in myocardial infarction patients treated by early revascularization?
Population

Depressed HRV should not guide post-MI risk stratification after reperfusion; leaves open whether prior prognostic links persist in contemporary cohorts.
Observational
Does depressed heart rate variability correlate with long-term prognosis in myocardial infarction patients treated by early revascularization?
p-value: p== 0.001
Traditional heart rate variability parameters lack prognostic significance for long-term outcomes in patients with recent complicated MI treated with immediate coronary reperfusion.
Compostella et al. (2017) conducted an observational in Acute myocardial infarction. Depressed heart rate variability was evaluated on All-cause or cardiac death (p== 0.001). Depressed heart rate variability recorded in the subacute phase of myocardial infarction did not correlate with long-term outcomes in patients treated with immediate coronary reperfusion.
