Background— The predictive value of heart rate variability (HRV) in chronic failure (CHF) has never been tested a comprehensive multivariate model using short-term laboratory recordings designed to avoid the confounding effects respiration and behavioral factors. Methods Results— A survival for identification sudden (presumably arrhythmic) death was developed with data from 202 consecutive patients referred between 1991 1995 moderate severe CHF (age 52±9 years, left ventricular ejection...
Despite the rational expectation for a survival benefit produced by exercise training among post-myocardial infarction (MI) patients, direct evidence remains elusive. Clinically, changes in autonomic balance toward lower vagal activity have consistently been associated with increased mortality risk; conversely, both control and post-MI dogs, improved reflexes prevented sudden death. Accordingly, we tested hypothesis that training, if accompanied shift of an marker such as baroreflex...
Sleep and exertional periodic breathing are proverbial in chronic heart failure (CHF), each alone indicates poor prognosis. Whether these conditions associated whether excess risk may be attributed to respiratory disorders general, rather than specifically during sleep or exercise, is unknown.We studied 133 CHF patients with left ventricular ejection fraction (LVEF) < =40%. During 1170+/-631 days of follow-up, 31 (23%) died. Nonsurvivors had higher New York Heart Association class,...
ABSTRACT Background Left Ventricular Assist Device (LVAD) implantation is an important treatment option for patients with advanced CHF. Referral to early, intensive cardiac rehabilitation (CR) program in these seems still underused. This observational descriptive study aimed evaluate the feasibility and efficacy of early CR LVAD recipients, also comparing results a matched group HFrEF patients. Methods The involved due who were admitted our post‐acute from several surgery wards 2009 2023....
The study aims were to validate the cardiopulmonary exercise testing (CPET) parameters recommended by European Society of Cardiology 2008 Guidelines for risk assessment in heart failure (HF) (ESC-predictors) and verify predictive role 11 supplementary CPET (S-predictors) parameters.We followed 749 HF patients cardiovascular death urgent transplantation 3 years: 139 (19%) had cardiac events. ESC-predictors - peak oxygen consumption (VO(2)), slope minute ventilation vs carbon dioxide...
Over the years left ventricular assist devices (VADs) have become more durable and reliable, smaller, simpler, easier to implant comfortable. The extensive experience now acquired shows successful hospital discharge with VAD use. We are entering an era in which long-term mechanical circulatory support will play increasing role approach end-stage heart failure (HF); at same time, extension of VADs into destination therapy has revealed limitations our understanding these populations. This...
In the present context of an aging population, limited donor heart availability, improved reliability mechanical cardiac support and patient outcomes, ventricular assist device (VAD) options to end-stage failure patients are rapidly expanding. addition, both smaller size lighter weight pumps now produced early evidence that these third generation devices may be associated with lower risk infection right will probably lead greater physician acceptability. This is first a two-part review on...
In continuous-flow left ventricular assist device (LVAD) recipients, little is known about the relative pump- and ventricle-generated blood flow (PBF LVBF, respectively) contribution to peak systemic perfusion during incremental exercise how PBF/LVBF interplay capacity may be affected by pump speed increase. Twenty-two LVAD recipients underwent ramp cardiopulmonary tests at fixed increasing (+ 1.5% of baseline speed/10 W workload increase), echocardiography NT-proBNP dosage. Peak was...
Exercise ventilation/perfusion matching in continuous-flow left ventricular assist device recipients (LVAD) has not been studied systematically. Twenty-five LVAD and two groups of 15 reduced ejection fraction chronic heart failure (HFrEF) patients with peak VO2 matched to that (HFrEF-matched) ≥14 ml/kg/min (HFrEF≥14), respectively, underwent cardiopulmonary exercise testing arterial blood gas analysis, echocardiogram venous sampling for renal function evaluation. Arterial-end-tidal PCO2...
Background Exercise oscillatory ventilation is an ominous outcome sign in heart failure due to reduced left ventricular ejection fraction; currently, the prevalence of exercise unknown assist device recipients. Methods We studied cardiopulmonary testing fraction or patients and was defined according Kremser's criteria. Results The occurrence similar either (192 patients, 8%) (85 recipients, 10%), even though mean peak oxygen consumption elevated ventilatory response slope lower higher...
The indication for cardiopulmonary exercise testing (CPET) in predictive evaluation has been extended beyond chronic heart failure (HF) patients to include asymptomatic left ventricular dysfunction (ALVD) patients, but its prognostic value is still unclear. We aimed verify if CPET can predict outcome ALVD and identify which of the parameters HF are also effective patients.We screened (LVEF ≤ 40% without symptoms) cardiac death, compared peak oxygen consumption (pVO2), exertional oscillatory...
