Pediatric heart transplant demand rises amid severe donor shortage

Advances in pediatric heart care are helping more children survive long enough to receive a transplant-but a critical shortage of donor hearts means too many are still dying while they wait, experts warned today at the International Society for Heart and Lung Transplantation (ISHLT) 46th Annual Meeting and Scientific Sessions.

The heart's constant beating suppresses tumor growth in cardiac tissues

The heart's constant beating may actively suppress tumor growth in cardiac tissues, a new study reports. This is because cellular pathways in these tissues alter gene regulation in cancer cells to keep them from proliferating.

Unraveling the mystery of cognitive resilience in aging brains

Some brains resist Alzheimer's, even when the disease is already present. Researchers at the Netherlands Institute for Neuroscience have found that this likely depends on how specific brain cells, known as immature neurons, respond to damage caused by the disease.

Trends reveal growing burden of deaths from non-ischemic cardiogenic shock

New data from the CDC WONDER database finds deaths from heart attack-related cardiogenic shock (CS) decreased between 1999 and 2020, but deaths linked to heart failure (HF) and abnormal heart rhythms have risen sharply since 2010, particularly among men.

M-TEER procedure effectively treats mitral regurgitation in patients with calcification

Results from a new analysis show that patients with mitral annular calcification (MAC) who undergo minimally invasive mitral transcatheter edge-to-edge repair (M-TEER) experience similar reductions in mitral regurgitation (MR) and improvement in quality of life compared to those seen in patients without calcification.
