A study by the University of São Paulo (USP) in Brazil, published recently in the journal Autophagy, helps to elucidate part of the mechanism whereby aerobic exercise protects the sick heart. The benefits of exercise range from prevention of cachexia -- severe loss of weight and muscle mass -- and control of arterial blood pressure to improved cardiac function, postponing a degenerative process that causes progressive heart cell death. About 70% of heart failure patients die from the condition within five years.
Patients at risk of heart attacks and strokes may be spotted earlier thanks to a diagnosis tool that uses near-infrared light to identify high-risk arterial plaques, according to research carried out at WMG, University of Warwick, the Baker Institute and Monash University.
Ever more people are suffering from cardiac insufficiency. The main cause of reduced cardiac functionality lies in the irreversible loss of cardiac muscle cells due to disease, especially ischemic diseases such as cardiac infarction. There is still no treatment to reverse damage of this nature. Research is ongoing to develop methods of repairing such damage to normalize cardiac function. A promising approach: cardiac muscle tissue made of spider silk.
A new Michigan State University study on 240 emergency room patients shows just how much of a role a person's cholesterol plays, when in a crystallized state, during a heart attack.
A new University of Liverpool study, published in Brain and Behaviour, identifies simple measures that could substantially improve the quality of life of stroke survivors with visual impairments.
Historically, from the 1930s to the 1950s, the rate of cardiovascular disease in high-income countries was high. Since the mid-1970s, the rate of cardiovascular disease has declined in high income countries, possibly due to socioeconomic inequalities and better management of risk factors for coronary heart disease among the wealthy.
When astronauts travel in space they can't see or even feel radiation. However, NASA's Human Research Program (HRP) is studying the effects radiation plays on the human body and developing ways to monitor and protect against this silent hazard.
A new University of Michigan study finds slightly more than half of heart patients are admitted to the CICU for noncardiac conditions, such as sepsis or renal failure, rather than for a heart condition.
Research led by the head of the Barrow Neurological Institute and published in the July 20, 2017 issue of The New England Journal of Medicine reveals that subarachnoid hemorrhages, which are caused by ruptured brain aneurysms, account for 5-10 percent of all strokes and are best managed by experienced and dedicated experts at high-volume centers with neurosurgeons, endovascular surgeons and stroke neurologists.
A new study has shown that following brain ischemia caused by cerebral blockage in mice both immediate and delayed reduction in body temperature helped limit cell death and levels of a protein called dynamin.
