Forty percent of deaths attributed to cardiac arrest are not sudden or unexpected, and nearly half of the remainder are not arrhythmic – the only situation in which CPR and defibrillators are effective.

UCSF scientists have improved mobility in rats that had experienced debilitating strokes by using electrical stimulation to restore a distinctive pattern of brain cell activity associated with efficient movement.

The use of newer blood-thinners for patients at risk of stroke may lead to two fewer days in the hospital for those who experience complications, with the same survival rate as the older drug warfarin.

The effects of low gravity and radiation on the musculoskeletal, cardiovascular and immune systems are some of the health impacts from space travel that UCSF scientists are researching.

UCSF researchers have devised a new term, “sudden neurological death,” to describe apparent sudden cardiac deaths that actually were due to neurological causes.

Reducing sugar consumption in obese children, rather than cutting calories or starch, or losing weight, leads to a sharp decline in triglycerides and a key protein called ApoC-III – two features that are associated with heart disease in adulthood.

Zika virus can infect numerous cell types in the human placenta and amniotic sac, according to researchers at UCSF and UC Berkeley who show in a new paper how the virus travels from a pregnant woman to her fetus.

Nearly half of all atrial fibrillation patients at the highest risk for stroke are not being prescribed blood thinners by their cardiologists, according to a new study by researchers at the UC San Diego and UC San Francisco schools of medicine.
