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.

Checking the heartbeat of babies in the womb is set to become more accurate and less stressful for expectant mothers thanks to research.

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 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.

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.

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.

Researchers have discovered a micropeptide molecule that can restore normal heart function in mice, according to a new study.

Using a statistical technique called network meta-analysis, researchers have combined the results of dozens of studies of dietary oils to identify those with the best effect on patients' LDL cholesterol and other blood lipids.

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.

An international team of researchers has shown in mice that a healthy gut microbiome is important for recovery after a heart attack.

Medicines commonly prescribed to reduce people's risk of heart attack may have limited use for treating other diseases, research suggests.

The largest ever genetic analysis of over one million people has identified 535 new genes associated with high blood pressure.

New findings suggest that diet is a major contributor for the increased risk of hypertension in black compared to white Americans.

Boosting testosterone levels with hormone supplements may not be safe or appropriate for all men with low testosterone (low T), according to new research.

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.

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.

One in two women and one in three men will likely be diagnosed with dementia, Parkinson's disease, or stroke in their lifetime, estimate Dutch researchers in an observational study.

Delaying pregnancy may increase the risk of cardiovascular disease in both women and their children, with boys at higher risk of disease, according to a new study.

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.

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.
