Advanced Science, EarlyView.A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.

Automated and Interpretable Patient ECG Profiles for Disease Detection, Tracking, and Discovery [PDF]
arXiv, 2018 The electrocardiogram or ECG has been in use for over 100 years and remains the most widely performed diagnostic test to characterize cardiac structure and electrical activity. We hypothesized that parallel advances in computing power, innovations in machine learning algorithms, and availability of large-scale digitized ECG data would enable extending ...

Left ventricular hypertrophy induced by weight excess in children and adolescents [PDF]
, 2019 Background: Obesity is associated with left ventricular hypertrophy, an independent risk factor of cardiovascular morbidity. The aim of the present study was to evaluate obesity-induced left ventricular hypertrophy in overweight/obese children and ...

The pathophysiology of diastolic heart failure [PDF]
, 2010 Whilst resting disturbances of both diastolic and long-axis systolic function are observed in patients with heart failure who have normal left ventricular ejection fraction, recent evidence suggests that dynamic disturbances in cardiac function occur ...

Evaluation of Left Ventricular Diastolic Function by Echocardiography [PDF]
, 2011 The normal cardiac cycle consists of two phases, systole and diastole, which are repeated over time to maintain an adequate cardiac output. The systole has been traditionally regarded as the main capital phase, leaving at diastole as a secondary process and almost forgotten.

Advanced Science, EarlyView.Doxorubicin‐induced cardiomyopathy involves mitochondrial energy metabolism dysfunction, exacerbated by cardiomyocyte‐specific Slc25a49 deficiency via oxidative phosphorylation (OXPHOS) suppression and glycolysis activation. The Slc25a49–glucose‐6‐phosphate (G6P)–activator protein‐1 (AP‐1) axis drives myocardial injury by upregulating Sln, disrupting ...

$ν$-net: Deep Learning for Generalized Biventricular Cardiac Mass and Function Parameters [PDF]
arXiv, 2017 Background: Cardiac MRI derived biventricular mass and function parameters, such as end-systolic volume (ESV), end-diastolic volume (EDV), ejection fraction (EF), stroke volume (SV), and ventricular mass (VM) are clinically well established. Image segmentation can be challenging and time-consuming, due to the complex anatomy of the human heart ...

Alterations in left ventricular diastolic function with doxorubicin therapy
Journal of the American College of Cardiology, 1987 To determine whether impaired diastolic function may be an early sign of doxorubicin cardiotoxicity, a retrospective study was performed in 12 patients who had undergone serial radionuclide angiography and were found to have a left ventricular ejection fraction of 55% or more before doxorubicin (Adriamycin) treatment and during follow-up. Average rapid

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]
, 2012 OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...
