Tratamiento de la insuficiencia cardíaca avanzada mediante estimulación biventricular. Experiencia inicial en una serie de 22 casos consecutivos [PDF]

, 2003
Recent data suggest that biventricular pacing may play an important role in treating advanced heart failure in the presence of a significant interventricular and/or intraventricular conduction disorder by correcting cardiac ...

Right heart failure after chemotherapy

Cleveland Clinic Journal of Medicine, 1991
Cardiotoxicity associated with chemotherapeutic agents used in the treatment of cancer is well-documented. Usually this cardiotoxicity presents as a distinct syndrome in which the left ventricle is more seriously affected than the right ventricle. A case of severe right-sided ventricular dysfunction shortly after an aggressive cycle of chemotherapy for

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Sex-based considerations for implementation of ventricular assist device therapy

Frontiers in Cardiovascular Medicine, 2022
Women with advanced heart failure receive advanced surgical therapies such as durable left ventricular assist device (LVAD) implantation or heart transplantation at a rate much lower compared to males. Reasons for this discrepancy remain largely unknown.

Anomalous right pulmonary artery from the aorta [PDF]

, 2006
Anomalous origin of the right pulmonary artery is a rare form of congenital heart disease. It usually presents in early infancy with heart failure and rapid development of pulmonary hypertension. There are about 131 cases reported in the literature and

Bisoprolol Delays Progression Towards Right Heart Failure in Experimental Pulmonary Hypertension [PDF]

, 2012
Background— In pulmonary arterial hypertension (PH), sympathetic adrenergic activity is highly elevated. Sympathetic overactivity is a compensatory mechanism at first, but might be detrimental for cardiac function in the long run.

High-Altitude–Induced Right-Heart Failure [PDF]

Circulation, 2007
Rapid ascent to high altitudes may be a cause of acute mountain sickness and its malignant complications, cerebral edema and/or pulmonary edema.1 A previously healthy 58-year-old mountaineer presented with echocardiographic signs of right-heart failure within the first 24 hours of arrival in La Paz, Bolivia, at the altitude of 3700 m.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
