Why the study?
Is heart rate variability decreased during the early phase of acute myocardial infarction and associated with clinical severity and short-term mortality?
Is heart rate variability decreased during the early phase of acute myocardial infarction and associated with clinical severity and short-term mortality?
Heart rate variability is significantly reduced in the early phase of acute myocardial infarction and correlates with infarct severity and short-term mortality, suggesting its utility in early risk stratification.
No takes yet. Share an insight, caveat, or question.
May aid early AMI risk stratification; extends prior post-MI autonomic observations to the hyperacute phase but remains hypothesis-generating.
Casolo et al. (1992) studied this question.
