Low chronotropic response in post-myocardial infarction exercise test predicts worse prognosis in patients with preserved or mildly reduced left ventricular ejection fraction
A chronotropic response below 67 % of the maximal predicted heart rate is a negative prognostic marker in post-MI patients with preserved or mildly reduced LVEF. This threshold may help risk-stratify and guide management in this population.
