Novel approaches to heart rate modulation in chronic heart failure.
Copyright © Polskie Towarzystwo Kardiologiczne INTRODUCTION The most recent version of the European Society of Cardiology (ESC) Guidelines for the management of heart failure (HF) has introduced two important innovations for the medical treatment of chronic HF with reduced ejection fraction (EF): mineralo-corticoid receptor antagonists (MCRA) and the If channel blocker ivabradine have now a rec...
متن کاملEffect of Exercise Training on Heart Rate Variability in Patients with Heart Failure After Percutaneous Coronary Intervention
Background: This study aims to evaluate the effect of exercise training on heart rate variability (HRV) and to determine the correlation between parameters of HRV and the ejection fraction in patients with heart failure after percutaneous coronary intervention.Material and Methods: Fifty patients with left ventricular ejection fraction ≤ 40% undergone percutaneous coronary intervention were r...
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 کاملOptimized Treatment and Heart Rate Reduction in Chronic Heart Failure
BACKGROUND Heart failure (HF) is a syndrome that leads to poor outcome in advanced forms. The neurohormonal blockade modifies this natural history; however, it is often suboptimal. OBJECTIVE The aim of this study is to assess at what percentage cardiologists used to treating HF can prescribe target doses of drugs of proven efficacy. METHODS A total of 104 outpatients with systolic dysfuncti...
متن کاملMetaiodobenzylguanidine and heart rate variability in heart failure.
It is assumed that the low-frequency power (LF) of heart rate variability (HRV) increases with progress of congestive heart failure (CHF), therefore positively correlating with cardiac 123I-metaiodobenzylguanidine (MIBG) washout. It is demonstrated here that HRV, including normalized LF, correlated inversely with MIBG washout and positively with the ratio of heart-to-mediastinum MIBG activity i...
