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...

Detection of congestive heart failure in dogs by Doppler echocardiography.

BACKGROUND Echocardiographic prediction of congestive heart failure (CHF) in dogs has not been prospectively evaluated. HYPOTHESIS CHF can be predicted by Doppler echocardiographic (DE) variables of left ventricular (LV) filling in dogs with degenerative mitral valve disease (MVD) and dilated cardiomyopathy (DCM). ANIMALS Sixty-three client-owned dogs. METHODS Prospective clinical cohort ...

Tissue doppler echocardiography in the diagnosis of heart transplantation rejection.

BACKGROUND Endomyocardial biopsy (EMB) is the gold standard method for the diagnosis of cellular rejection (CR) after heart transplantation (HT). OBJECTIVE To test the hypothesis that tissue Doppler imaging (TDI) could detect CR > 3A and add diagnostic information compared to conventional Doppler. METHODS Fifty-four HT patients underwent 129 EMB and a TDI echocardiographic study within 24 h...

Variable 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,...

Tissue Doppler Imaging in Coronary Artery Diseases and Heart Failure

Recent studies have explored the prognostic role of TDI-derived parameters in major cardiac diseases, such as coronary artery disease (CAD) and heart failure (HF). In these conditions, myocardial mitral annular systolic (S') and early diastolic (E') velocities have been shown to predict mortality or cardiovascular events. In heart failure non invasive assessment of LV diastolic pressure by tran...
