Heart rate recovery and tissue Doppler echocardiography in heart failure.
BACKGROUND Previous research has demonstrated the prognostic value of echocardiography with tissue Doppler imaging (TDI) in the heart failure (HF) population. Heart rate recovery (HRR) has also recently shown promise as a prognostic marker. HYPOTHESIS We hypothesize echocardiography with TDI and HRR will be significantly correlated and both will provide prognostic information. METHODS A tot...
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 کاملCorrelation between low T3 syndrome and mortality rate in patients with systolic heart failure
Introduction: This study was performed to evaluate the prevalence of low T3 syndrome among patients with heart failure and to assess the correlation between decreased level of tri iodothyronin (T3) with mortality rate. Methods: In a prospective cross-sectional study, 91 patients with systolic heart failure were admitted to Mohammadi hospital in Bandar Abbas in 2008.Thyroid function test w...
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...
متن کاملOxygen Kinetics and Heart Rate Response during Early Recovery from Exercise in Patients with Heart Failure
Background. The purpose of this study was to assess the post-exercise O(2) uptake and heart rate response in patients with heart failure (HF) in comparison to healthy individuals. Methods and Results. Exercise testing of all subjects was conducted according to the RITE-protocol. The study subjects were classified according to their peak oxygen uptake (peak VO(2)) in four groups: healthy individ...
