BACKGROUND: This study was conducted to determine the association between aortic pulse pressure (APP) and left ventricular (LV) filling pressure in the elderly of both genders. METHODS: A total of 211 stable elderly subjects (age ≥ 65 years, mean age 72.1 ± 5.2 years, 53.6% women) who underwent invasive coronary angiography (ICA) for the evaluation of coronary artery disease (CAD) were prospectively investigated. APP was measured in the ascending aorta using a pigtail catheter immediately before ICA...

AIMS: Heart failure (HF) in late pregnancy and postpartum (HFPP) of which peripartum cardiomyopathy (PPCM) comprises the larger part, is still a rare occurrence in Sweden. Population-based data are scarce. Our aim was to characterise HFPP and determine the incidence and mortality in a Swedish cohort. METHODS AND RESULTS: Through merging data from the National Inpatient, Cause of Death, and Medical Birth Registers, we identified ICD-10 codes for HF and cardiomyopathy, within 3 months before delivery up to 6 months postpartum...

BACKGROUND: High intensity training (HIT) is superior to moderate aerobic training (MAT) for improving quality of life in congestive heart failure (CHF) patients. Speckle tracking echocardiography (STE) has recently been suggested for estimation of left ventricle global and regional function. AIMS: We evaluated the utility of STE for characterizing differences in cardiac function following MAT or HIT in a CHF rat model. METHODS AND RESULTS: Following baseline physiological assessment, CHF was induced by coronary artery ligation in Sprague-Dawley rats...

BACKGROUND: Despite the availability of validated risk scores for survival in heart failure (HF), individualized estimates are not typically provided directly to patients. METHODS AND RESULTS: We explored patient perspectives regarding conveyance of individualized Seattle Heart Failure Model (SHFM) survival estimates. In 2014 and 2015, 24 HF patients completed a semi-structured interview at initial offering of SHFM survival estimates (baseline) and a follow-up interview...

BACKGROUND: Recent studies have suggested a high prevalence of cardiac amyloidosis (CAm) in heart failure (HF) patients. CAm might be underdiagnosed owing to low clinical suspicion. METHODS AND RESULTS: We performed retrospective analysis of 259 patients with HF and ejection fraction (EF) ≥50% referred for endomyocardial biopsy. Seventy-three (28%) had CAm. Multivariable independent predictors of CAm were identified. Over a mean follow-up of 2.6 ± 3.3 years, CAm patients had worse survival than those without (1...

OBJECTIVE: We assessed the hypothesis that interstitial myocardial fibrosis measured by cardiac magnetic resonance imaging (CMR) predicts left ventricular (LV) beneficial remodeling in non-ischemic dilated cardiomyopathy (NIDCM) after heart failure (HF) treatment including mineralocorticoid receptor antagonists (MRA). BACKGROUND: The myocardial longitudinal relaxation time (T1) on CMR, can quantify myocardial fibrosis in the presence or absence of visually detectable late gadolinium (Gd) enhancement (LGE) MRA treatment produces beneficial remodeling in NIDCM...

AIMS: The Kansas City Cardiomyopathy Questionnaire (KCCQ) has emerged as a patient-centered, heart failure-specific health status measure. It currently lacks routine and widespread use in clinical practice or trials. The purpose of this study was to examine the correlation between KCCQ and cardiopulmonary exercise testing (CPET) parameters and clinical outcomes, in comparison with the New York Heart Association (NYHA) functional classification. METHODS AND RESULTS: We performed a single-centered, observational analysis of 432 patients who presented to the Heart Failure Department, completed the KCCQ, and underwent CPET...

BACKGROUND: Beliefs around deactivation of a left ventricular assist device (LVAD) vary substantially between clinicians, institutions, and patients. Therefore, we sought to understand perspectives regarding LVAD deactivation among cardiology and hospice/palliative medicine (HPM) clinicians. METHODS AND RESULTS: We administered a 41-item survey via electronic mail to members of 3 cardiology and 1 HPM professional societies. A convergent parallel mixed methods design was used...

BACKGROUND: Right ventricular (RV) dysfunction plays an important role in chronic heart failure (CHF). We evaluated the echocardiographic determinants of 1-year all-cause mortality in CHF patients with clinically relevant functional tricuspid regurgitation (TR). METHODS AND RESULTS: A total of 101 consecutive CHF patients (mean age 74 ± 10 years, 53% male) with moderate or severe functional TR were enrolled. Each patient underwent at least 2 echocardiography examinations in an interval of >6 months...

BACKGROUND: Although fibrosis seems to be prognostic for adverse outcomes in adults with idiopathic dilated cardiomyopathy (IDC), little is known about the prevalence and development of fibrosis in pediatric IDC hearts. We hypothesized that there is less activation of fibrosis at a molecular level in pediatric IDC hearts than in failing adult hearts. METHODS AND RESULTS: Pediatric hearts were analyzed histologically to determine the prevalence of fibrosis. Left ventricular tissue from adult and pediatric IDC hearts and adult and pediatric nonfailing (NF) hearts were subjected to quantitative reverse-transcription polymerase chain reaction to study the expression of important mRNAs that affect fibrosis...

BACKGROUND: Medication nonadherence contributes to hospitalizations in recently discharged patients with heart failure (HF). We aimed to test the feasibility of telemonitoring medication adherence in patients with HF. METHODS AND RESULTS: We randomized 40 patients (1:1) hospitalized for HF to 30 days of loop diuretic adherence monitoring with telephonic support or to passive adherence monitoring alone. Eighty-three percent of eligible patients agreed to participate...

BACKGROUND: Heart failure (HF) is the most common diagnosis in hospitalized patients over 65 years of age. Although these patients often need specialist-directed palliative care, <10% ever receive these services. This may be due to a lack of evidence examining the benefits of palliative care for these patients. To understand the current state of research on the interface of palliative care and HF, we examined trends in publications, presentations at national meetings, and NIH funding...

BACKGROUND: Cardiac resynchronization therapy (CRT) induces structural and electrical remodelling (ER) in heart failure (HF) patients. Our aim was to assess time course of ER of native conduction and mechanical remodelling after CRT and impact of CRT-induced ER on clinical outcome. METHODS AND RESULTS: We prospectively included 62 patients (aged 66±10 years). Echocardiographic and ECG parameters were measured at baseline, 1, 3, 6, 9, and 12 months after implantation...

REVIEW
Hoong Sern Lim, Neil Howell, Aaron Ranasinghe
The use of left ventricular assist devices (LVADs) has increased significantly over the last few years, in part because heart transplant activity has plateaued, but also the improving clinical outcomes with contemporary continuous flow LVAD. As such, there is now a growing population of patients with continuous flow LVADs. Management of these patients is complicated by the altered circulatory physiology, as continuous flow LVADs provide a parallel circulation from the heart to the aorta, which interacts with the native left heart (systemic) circulation with consequent effects on the right heart circulation...

REVIEW
Hoong Sern Lim, Neil Howell, Aaron Ranasinghe
Extracorporeal life support (ECLS) describes a system that involves drainage from the venous circulation and return via an oxygenator into the arterial circulation (veno-arterial extracorporeal membrane oxygenation). ECLS provides effective cardiopulmonary support, but the parallel circulation has complex effects on the systemic and pulmonary circulatory physiology. An understanding of the physiological changes is fundamental to the management of ECLS. In this review, the key physiological concepts and the implications on the clinical management of ECLS are discussed...
