Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

Advanced Science, EarlyView.
This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...

Left Ventricular Diastolic Function in Normal Human Pregnancy [PDF]

Circulation, 1999
Background —Little information is available about changes in left ventricular diastolic function during pregnancy. We used mitral inflow and pulmonary venous flow profiles to evaluate left ventricular diastolic function in 37 healthy pregnant women 26 to 41 years old (mean, 32 years).

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Hyperglycemia Has a Greater Impact on Left Ventricle Function in South Asians Than in Europeans [PDF]

, 2013
OBJECTIVE Diabetes is associated with left ventricular (LV) diastolic and systolic dysfunction. South Asians may be at particular risk of developing LV dysfunction owing to a high prevalence of diabetes.

Left ventricular diastolic function in congenital myotonic dystrophy [PDF]

Archives of Disease in Childhood, 1999
Examination of left ventricular function and conduction abnormalities in myotonic dystrophy.Twelve patients (median age, 13.7 years) with myotonic dystrophy had detailed electrocardiography and echocardiography performed. Echocardiographic parameters were compared with body surface area (BSA) matched median normal values.Fractional shortening was ...

Early Outcomes After Total Arch Replacement With Frozen Elephant Trunk in Elderly Patients With Acute Type A Aortic Dissection

AGING MEDICINE, EarlyView.
Across seven centers (2015–2023), we studied 1634 ATAAD patients undergoing TAR+FET and, after propensity matching (n = 699), compared elderly (≥ 60) versus non‐elderly (< 60) outcomes. Elderly patients had higher 30‐day mortality and complications (log‐rank p = 0.002), supporting individualized hybrid strategies, organ‐protective perioperative care ...
