Fluid overload is common after neonatal congenital #cardiac surgery (CCS) and is frequently managed with continuous furosemide infusions requiring iterative dose titration. An interpretable prediction model could support more consistent early postoperative dosing decisions. We hypothesized that a novel, interpretable machine learning approach could accurately predict furosemide dosing decisions in neonates following CCS. We identified… Continue reading A Novel, Interpretable Machine Learning Model Predicts Furosemide Dosing After Congenital Cardiac Surgery

Mechanical load inhibits cancer growth in mouse and human hearts
INTRODUCTIONThe #heart is rarely affected by #cancer ; both primary cardiac tumors and metastases are uncommon despite the high vascularization of the myocardium. The mechanisms underlying this resistance remain unclear.RATIONALEMechanical load has been proposed as a major mechanism halting cardiomyocyte proliferation early after birth, thus limiting the regenerative potential of the adult mammalian heart. We… Continue reading Mechanical load inhibits cancer growth in mouse and human hearts
Skeletal and cardiac muscle longitudinal associations in the Baltimore Longitudinal Study of Aging (BLSA)
Background: #Sarcopenia, the age-related loss of skeletal muscle mass and function, has been linked to adverse health outcomes. Cross-sectional associations have been observed between skeletal and cardiac muscle mass and function in healthy, community-dwelling older adults during normative aging. Further longitudinal studies on the skeletal muscle-cardiac axis during aging are needed to inform the temporal… Continue reading Skeletal and cardiac muscle longitudinal associations in the Baltimore Longitudinal Study of Aging (BLSA)
#Electroacupuncture modulates myocardial insulin signaling and inflammatory markers in a rat model of type 2 #diabetes
Objective: To evaluate the effects of electroacupuncture (EA) on myocardial insulin resistance (IR) in Zucker diabetic fatty (ZDF) rats, an established model for type 2 diabetes mellitus (T2DM).Methods: Twenty-four ZDF-Leprfa/fa rats were randomized to: (1) ZDF group (n = 8); (2) ZDF + PIO (pioglitazone) group (n = 8); and (3) ZDF + EA group… Continue reading #Electroacupuncture modulates myocardial insulin signaling and inflammatory markers in a rat model of type 2 #diabetes
Psychosocial #stress amplifies inflammation through NLRP3 Inflammasome activated by endoplasmic reticulum stress in the mouse #heart
Psychosocial stress (PSS) is a significant contributor of inflammation and CVD.• NLRP3 inflammasome activation amplifies inflammation in response to PSS.• ER stress is a key upstream mechanism that triggers NLRP3 inflammasome activation.• This study reveals mechanisms and targets to reduce inflammation caused by PSS. AbstractPsychosocial stress (PSS) affects all humans with different intensities and is… Continue reading Psychosocial #stress amplifies inflammation through NLRP3 Inflammasome activated by endoplasmic reticulum stress in the mouse #heart
Hybrid hydrogel–extracellular matrix scaffolds identify biochemical and mechanical signatures of #cardiac #ageing
Extracellular matrix remodelling of cardiac tissue is a key contributor to age-related cardiovascular disease and dysfunction. Such remodelling is multifaceted including changes to the biochemical composition, architecture and mechanics, clouding our understanding of how and which extracellular matrix properties contribute to a dysfunctional state. Here we describe a decellularized extracellular matrix–synthetic hydrogel hybrid scaffold that… Continue reading Hybrid hydrogel–extracellular matrix scaffolds identify biochemical and mechanical signatures of #cardiac #ageing
Leadless #pacing in young patients
Leadless pacing has been established as an effective and safe therapy. The majority of published data relates to an older population. However, this therapy may be particularly attractive for a younger (<40 years) population where the complications of transvenous devices can be enhanced. These include having leads in the vasculature for a longer period of… Continue reading Leadless #pacing in young patients
Impact of #Mental Health Treatment on Outcomes in Patients With #Heart Failure and Ischemic Heart Disease
BackgroundThere is conflicting evidence as to the impact of mental health treatment on outcomes in patients with heart disease. The aim of this study was to examine whether individuals who received mental health treatment for anxiety or depression after being hospitalized for ischemic disorders or heart failure had a reduced frequency of rehospitalizations, emergency department… Continue reading Impact of #Mental Health Treatment on Outcomes in Patients With #Heart Failure and Ischemic Heart Disease
Stress test abnormalities reveal more than just cardiovascular risks, Mayo Clinic study finds
The treadmill exercise test with electrocardiogram (ECG), also known as an exercise stress test, is one of the most familiar tests in medicine. While exercise testing typically is focused on diagnosing coronary artery disease, a recent study from Mayo Clinic finds that exercise test abnormalities, such as low functional aerobic capacity, predicted non-cardiovascular causes of death such as… Continue reading Stress test abnormalities reveal more than just cardiovascular risks, Mayo Clinic study finds
