Heart rate in chronic heart failure: an overlooked risk factor.
Heart rate measured by palpation and more recently by auscultation has been used for centuries to assess the cardiovascular condition of patients (Figure 1). It is, however, only recently that the importance of heart ratemeasurement as aprognostic factorhasbeen recognized in unselected healthy populations, patients with hypertension or coronary artery disease, after myocardial infarction, and i...
متن کاملPotential interests of heart rate lowering drugs.
Epidemiological studies have shown that a high heart rate at rest is a risk factor for global and cardiovascular mortality. 1–3 A rapid heart rate is associated with a variety of prognostic factors indicative of worse heart conditions (for example , hypoxaemia, anaemia, alcohol consumption , low physical training status). The link between a high resting heart rate and an increase in overall and...
متن کاملEvaluation of heart-rate turbulence as a new prognostic marker in patients with chronic heart failure.
The significance of heart-rate turbulence (HRT) in patients with chronic heart failure (CHF) was evaluated to examine whether it is sensitive to the risk of ventricular tachycardia (VT). HRT is reported to predict the prognosis after myocardial infarction (MI), but its prognostic value in patients with CHF remains unknown. HRT was measured in 50 CHF patients (left ventricular ejection fraction ...
متن کاملVariable effects of physical training of heart rate variability, heart rate recovery, and heart rate turbulence in chronic heart failure.
BACKGROUND Heart rate variability (HRV), heart rate turbulence (HRT), and heart rate recovery (HRR), indices that reflect autonomic nervous system (ANS) activity, are outcome predictors in patients with chronic heart failure (CHF). It is not clear, however, whether they reflect the same components of ANS activity. No study has examined the effects of physical training (PT) training on HRV, HRT,...
متن کاملHeart rate turbulence in patients with chronic heart failure.
BACKGROUND Heart rate turbulence (HRT) has been shown to predict the prognosis after myocardial infarction (MI), but its prognostic value in patients with chronic heart failure (CHF) has not yet been well established. AIM To evaluate HRT in patients with CHF and assess the prognostic significance of HRT in this group. METHODS The study group consisted of 82 patients with CHF and left ventri...
