New drug could sustain oxygen-starved hearts

Fri, 10/19/2018 - 13:15
In new studies, a novel oxygen-delivery therapeutic restored the function of oxygen-starved heart tissue in an animal model of global hypoxia. Unlike its experimental predecessors, the new drug does not appear to cause systemic side effects or overcorrect with excessive blood oxygenation, which can itself be toxic. Instead, the new drug delivers its precious oxygen cargo only to the tissues that need it most.

Why does diabetes cause heart failure?

Thu, 10/18/2018 - 09:54
A new study reveals how, on a cellular level, diabetes can cause heart failure. The findings could lead to medications to treat and perhaps prevent heart failure in diabetes patients.

Pre-eclampsia linked to an increased risk of dementia later in life

Wed, 10/17/2018 - 18:49
Pre-eclampsia is associated with an increased risk of later dementia, particularly vascular dementia, caused by reduced blood supply to the brain due to diseased blood vessels, finds a large study.

Modifiable dementia risk factor in older adults identified

Tue, 10/16/2018 - 13:20
Stiffness of the aorta -- more so than blood pressure or subclinical brain disease -- is a key risk factor for dementia. Since aortic stiffness can be reduced by medication and healthy lifestyle changes, these results suggest that people can still lower their dementia risk well into old age.

Does open heart surgery affect cognitive abilities?

Fri, 10/12/2018 - 11:02
Understanding how heart valve surgery may affect your cognition is important for older adults. To learn more, researchers reviewed studies to see how patients' cognition changed before and after heart valve surgery. They also looked at whether surgeries on two types of heart valves, the mitral or the aortic, were associated with better or worse outcomes.

Gene mutation points to new way to fight diabetes, obesity, heart disease

Tue, 10/09/2018 - 13:58
Researchers say they have discovered a gene mutation that slows the metabolism of sugar in the gut, giving people who have the mutation a distinct advantage over those who do not. Those with the mutation have a lower risk of diabetes, obesity, heart failure, and even death.

Even light drinking increases risk of death

Wed, 10/03/2018 - 10:27
Analyzing data from more than 400,000 people, researchers have found that consuming one to two drinks four or more times per week -- an amount deemed healthy by current guidelines -- increases the risk of premature death by 20 percent.

Weekday mornings are no longer peak times for sudden cardiac arrest

Tue, 10/02/2018 - 14:48
Heart experts have long believed that weekday mornings -- and especially Mondays -- were the danger zones for unexpected deaths from sudden cardiac arrests. But a new study shows those peak times have disappeared and now, sudden cardiac arrests are more likely to happen on any day at any time.

Genetics of cholesterol point to possible drug targets for heart disease, diabetes

Mon, 10/01/2018 - 11:42
From the DNA of nearly 300,000 veterans, scientists have singled out a handful of genetic mutations that not only govern levels of cholesterol, but may also inform the development and use of drugs for cardiovascular disease and diabetes, according to researchers.

Keeping our cells stable: A closer look at microtubules

Mon, 10/01/2018 - 10:19
Microtubules help to regulate cell structure throughout our bodies. A group of researchers have used cryo-electron microscopy to shed light on how a certain protein keeps microtubules stable, and regulates microtubule-based transport within cells. The new insights could help to develop medical treatment for diseases such as dementia and heart failure.
