Transient baroreflex impairment early after MI may heighten arrhythmic vulnerability; leaves open whether targeted autonomic interventions improve outcomes.
Does acute myocardial infarction impair the baroreceptor control of heart rate in humans?
Acute myocardial infarction causes a marked but transient impairment of baroreceptor control of heart rate in humans, which recovers within approximately 10 days.
Osculati et al. (1990) studied this question.
