The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart's needs. A new study of mouse hearts reveals a previously unknown mechanism by which heart cells control their size by ramping up or stopping the production of a key factor called PABPC1.

A new study's findings point to potential for tweaking communication between human genes and advancing our ability to treat heart conditions and stimulate regenerative healing.

Persistent moderate to severe mental distress is linked to a significantly heightened risk of death among patients with stable coronary heart disease, finds research.

Using a new skin cell model, researchers have overcome a barrier that previously prevented the study of living tissue from people at risk for early heart disease and stroke. This research could lead to a new understanding of disease progression in aortic aneurysm -- ballooning of the large artery in the chest that carries blood from the heart to the body.

Socioeconomic inequalities are a public health challenge in cardiovascular disease and a new study examined the association of childhood family socioeconomic status in youth on measures of left ventricular mass and diastolic function 31 years later in adulthood.

A researcher is developing new miniature models to better understand the factors that lead to heart disease and sickle cell anemia.

In individuals with chronic kidney disease, targeting a systolic blood pressure to <120 mm Hg resulted in lower risks of cardiovascular events and premature death, compared with standard targeting to <140 mm Hg. There was a slightly faster decline in kidney function in the intensive group, but no increase in rates of kidney failure or serious adverse events.

Coronary artery disease may have persisted in human populations because the genes that cause this late-striking disease also contribute to having a greater numbers of children.

Researchers have found that genes for coronary heart disease (CAD) also influence reproduction, so in order to reproduce successfully, the genes for heart disease will also be inherited.

Scientists studying a mystery link between the dangerous pregnancy complication pre-eclampsia and an increased risk of heart disease in later life for both mother and child have uncovered important new clues.

Breast implants may impede an electrocardiogram (ECG) and could result in a false heart attack diagnosis, according to new research.

Results from four recent randomized clinical trials suggest that using medications that offer glucose control while reducing the risk for cardiovascular disease could improve patient outcomes.

A vaccine to immunize people against high levels of cholesterol and the narrowing of the arteries caused by build-up of fatty material (atherosclerosis) may be possible following successful results in mice. Now, a phase I trial in patients has started to see if the findings translate to humans.

The loss of a loved one, a dispute with your neighbour, infections or a fall – mental and physical stress can be triggers of a broken heart (broken heart syndrome). What is more, physical stress seems to be more dangerous than emotional stress, a study shows.

Health evices may reveal time and cause of death when autopsy fails, a new report suggests.

A novel smartphone application (app) has been developed that can direct first responders to cardiac arrest victims more than three minutes before the emergency services arrive. Each minute increases the chance of survival by 10%.

Pulsed cavitation ultrasound can be used to remotely soften human degenerative calcified biosprosthetic valves and significantly improve the valve opening function, according to a new study. This new noninvasive approach has the potential to improve the outcome of patients with severe bioprosthesis stenosis.

Despite mixed evidence recently about an association between atopic dermatitis and cardiovascular disease, a new study that analyzed more than 250,000 medical records suggests there is no link.

New research represents an important step towards characterizing the genetic basis of cardiovascular disease (CVD) risk in chronic immune-mediated inflammatory diseases (IMID).

A new study finds that stem cell therapy may harm heart disease patients.
