We evaluated the feasibility, tolerability, and efficacy of a strategy for transaxillary artery intra-aortic balloon pump placement for extended mechanical circulatory support of patients with postcardiotomy shock as a bridge to recovery. Patients requiring prolonged intra-aortic balloon pump support for postcardiotomy heart failure were identified. Intra-aortic balloon pump was tunneled through a 6-mm Dacron graft anastomosed to the right axillary artery. The intra-aortic balloon pump catheter is advanced under fluoroscopic guidance into the descending thoracic aorta...

Hypertrophic obstructive cardiomyopathy has been rising in prevalence, due to increased awareness and advanced imaging. For the symptomatic patient, pharmacological management remains an effective approach to the majority of patients with obstructive hypertrophic cardiomyopathy. However, a significant subset fails to improve sufficiently with medical therapy initially, or progressively becomes more symptomatic despite augmented medications over time. Most of the advances in the treatment of obstructive hypertrophic cardiomyopathy have therefore been made in the area of non-pharmacologic management, particularly septal reduction therapy...

In 2015, non-communicable diseases accounted for 39.5 million (70%) of the total 56.4 million deaths that occurred globally, of which 17.7 million (45%) were due to cardiovascular diseases. An elevated heart rate is considered to be one of the independent predictors and markers of future cardiovascular diseases. A variety of experimental and epidemiological studies have found that atherosclerosis, heart failure, coronary artery disease, stroke, and arrhythmia are linked to elevated heart rate. Although there are established drugs to reduce the heart rate, these drugs have undesirable side effects...

It is thought that at least 6,500 low-molecular-weight metabolites exist in humans, and these metabolites have various important roles in biological systems in addition to proteins and genes. Comprehensive assessment of endogenous metabolites is called metabolomics, and recent advances in this field have enabled us to understand the critical role of previously unknown metabolites or metabolic pathways in the cardiovascular system. In this review, we will focus on heart failure and how metabolomic analysis has contributed to improving our understanding of the pathogenesis of this critical condition...

BACKGROUND: Socioeconomically disadvantaged patients are at an increased risk for adverse heart failure (HF) outcomes based upon nonadherence to medications and diet. Physicians are also suboptimally adherent to prescribing evidence-based therapy for HF. METHODS: Congestive Heart Failure Adherence Redesign Trial (CHART) (NCT01698242) is a multicenter, bilevel, cluster randomized behavioral efficacy trial designed to assess the impact of intervening simultaneously on physicians and their socioeconomically disadvantaged patients (annual income <$30,000) having HF with reduced ejection fraction...

BACKGROUND: Recent reports of leaflet abnormalities (detected using advanced imaging) have raised questions regarding transcatheter aortic valve replacement (TAVR) durability. We sought to determine the incidence of valve hemodynamic deterioration (VHD) and its association with cardiovascular outcomes. METHODS AND RESULTS: Consecutive cases with paired postimplant and follow-up echocardiograms from November 2011 to March 2015 in the STS/ACC TVT Registry were allocated into 2 overlapping cohorts: early (paired echocardiograms at 0 and 30 days) and late (paired echocardiograms at 30 days and 1 year)...

Background: Acute effects of positive airway pressure (PAP) [including continuous PAP (CPAP) and adaptive servo-ventilation, an advanced form of bi-level PAP] on functional mitral regurgitation (fMR) in patients with heart failure (HF) with left ventricular (LV) systolic dysfunction remain unclear. Thus, whether PAP therapy reduces fMR in such patients with HF was investigated. Methods and Results: Twenty patients with HF and LV systolic dysfunction defined as LV ejection fraction (LVEF) <50% (14 men; mean LVEF, 35...

Quality of life and mental health of patients with severe heart failure with or without technical support for the left cardiac ventricle - a cross-sectional study Objectives: Chronic heart failure is associated with reduced quality of life (QoL) and poor prognosis. Support via a left ventricular assist device (LVAD) is an alternative to optimised medical management for patients with advanced heart failure. This study evaluated health-related QoL with both therapy options. METHODS: In this consecutive cross-sectional study, patients with LVAD support (n = 50) and patients with optimised medical management (n = 50) were interviewed comprehensively about various domains of QoL, emotional stress, perceived self-efficacy, social support, life satisfaction, and communication...

BACKGROUND: Heart failure (HF) is associated with cardiac autonomic denervation (AD), which can be non-invasively assessed by 123I-metaiodobenzylguanidine (123I-mIBG) scintigraphy and has prognostic implications. We aimed to study the relationship between myocardial contractility assessed by global longitudinal strain (GLS) and AD assessed by 123I-mIBG scintigraphy in advanced HF. METHODS/RESULTS: BETTER-HF is a prospective randomized clinical trial including HF patients (pts) submitted to cardiac resynchronization therapy (CRT) who are submitted to a clinical, echocardiographic, and scintigraphic assessment before and 6 months after CRT...

PURPOSE OF REVIEW: Patients with advanced heart failure require communication about goals of care, yet many challenges exist, leaving it suboptimal. High mortality rates and advances in the use of life-sustaining technology further complicate communication and underscore the urgency to understand and address these challenges. This review highlights current research with a view to informing future research and practice to improve goals of care communication. RECENT FINDINGS: Clinicians view patient and family barriers as more impactful than clinician and system factors in impeding goals of care discussions...

Importance: There is mixed evidence that blood pressure (BP) stabilizes or decreases in later life. It is also unclear whether BP trajectories reflect advancing age, proximity to end of life, or selective survival of persons free from hypertension. Objective: To estimate individual patient BP for each of the 20 years before death and identify potential mechanisms that may explain trajectories. Design, Study, and Participants: We analyzed population-based Clinical Practice Research Datalink primary care and linked hospitalization electronic medical records from the United Kingdom, using retrospective cohort approaches with generalized linear mixed-effects modeling...

Hypertrophic cardiomyopathy (HCM) affects millions of people around the world as one of the most common genetic heart disorders and leads to cardiac ischemia, heart failure, dysfunction of other organ systems, and increased risk for sudden unexpected cardiac deaths. HCM can be caused by single-point mutations, insertion or deletion mutations, or truncation of cardiac myofilament proteins. The molecular mechanism that leads to disease progression and presentation is still poorly understood, despite decades of investigations...

BACKGROUND: Atrial fibrillation (AF) is reported to be a less frequent cause of ischemic stroke in China than in Europe and North America, but it is not clear whether this is due to underestimation. Our aim was to define the true frequency of AF-associated stroke, to determine the yield of 6-day Holter ECG to detect AF in Chinese stroke patients, and to elucidate predictors of newly detected AF. METHODS: Patients with acute ischemic stroke or transient ischemic attack (TIA) were enrolled in a prospective, multicenter cohort study of 6-day Holter monitoring within 7 days after stroke onset at 20 sites in China between 2013 and 2015...

Aim: A case of asymptomatic aneurysm of spontaneous portosystemic venous fistula (SPVF) with the radiologic findings is described. Background: Although advances and more widespread use of ultrasound (US) and computed tomog -raphy angiography (CTA) have enabled more detection of SPVF in the liver, it is a rare entity. Case report: A 49-year-old male was referred to our hospital's nephrology outpatient clinic due to hypertension. Abdominal sonography examination detected a well-defined cystic lesion adjacent to the middle hepatic vein in the liver...

BACKGROUND: The neoadjuvant chemotherapy in HER2-positive breast cancer consists of a chemotherapy backbone and HER2-directed therapy. The increase in cardiotoxicity by the use of trastuzumab with an anthracycline-based regimen has led to the use of nonanthracycline-based alternative regimens. The docetaxel, carboplatin, and trastuzumab (TCH) are one such regimen. The efficacy and toxicity of this regimen have not been widely studied in Indian patients. AIMS: This retrospective study aims to evaluate the efficacy and toxicity of neoadjuvant TCH regimen in locally advanced and oligometastatic HER2-positive breast cancer in Indian patients...
