Impaired chronotropic response to physical activities in heart failure patients
BACKGROUND While exercise-based cardiac rehabilitation has a beneficial effect on heart failure hospitalization and mortality, it is limited by the presence of chronotropic incompetence (CI) in some patients. This study explored the feasibility of using wearable devices to assess impaired chronotropic response in heart failure patients. METHODS Forty patients with heart failure (left ventricu...
متن کاملImpaired Chronotropic Response to Exercise in Patients With Congestive Heart Failure
The mechanism responsible for the attenuated heart rate (HR) response to exercise in patients with congestive heart failure (CHF) was investigated in 46 normal subjects and 59 patients with CHF stratified by peak exercise oxygen consumption (Vo2). The peak exercise HR and the increment in HR from rest to peak exercise were decreased in CHF patients, and both correlated strongly with peak Vo2 (r...
متن کاملImpaired heart rate recovery and chronotropic incompetence in patients with heart failure with preserved ejection fraction.
BACKGROUND This study assessed the chronotropic response to exercise and heart rate (HR) recovery after exercise in a carefully phenotyped group of patients with heart failure with preserved left ventricular ejection fraction (HfpEF) and a control group of similar age and gender distribution. METHODS AND RESULTS We studied 41 patients with HfpEF, 41 healthy controls, and 16 hypertensive contr...
