It's difficult to study how the heart reacts to diseases and medications. Researchers at Harvard have now grown a model of a human left ventricle that spontaneously beats, marking a substantial step towards engineering entire hearts for more accurate testing of new treatments.

A large-scale meta-analysis collecting data from 79 trials has concluded that omega-3 supplements have little to no effect in preventing heart disease, stroke or death. The results contrast the common belief that omega-3 supplements confer a variety of beneficial cardiovascular protections.

A new study has revealed a previously undiscovered mechanism showing how caffeine can trigger the repair of heart muscles. The research, so far only involving mouse experiments, lends more weight to the growing body of observational evidence suggesting caffeine has beneficial health effects.

It’s not a huge newsflash that green tea has some pretty impressive health benefits, but a new study has identified a specific compound found in the tea that could be recruited into dissolving plaques that accumulate in blood vessels and lead to heart attacks and cardiovascular disease.

A new breakthrough at the University of Colorado is the latest advance in the burgeoning realm of anti-aging science, demonstrating how a chemically altered nutritional supplement may well reverse aging of the blood vessels, in turn giving cardiovascular health a vital boost.

The most common type of arrhythmia, atrial fibrillation is an irregular beating of the heart that can lead to strokes. And unless an electrocardiogram is being used, it can be difficult to detect. Soon, however, an app may be all that's required to do the job.

The one artificial heart that's approved for human use in the US is only intended to keep patients going until they can get a heart transplant. A new device being developed by the Oregon Health & Science University, however, is designed to be a permanent fix.

Inflammatory Bowel Disease (IBD) inflicts millions of people around the world with an increasing prevalence. A new study has found that people diagnosed with IBD have a significantly higher risk of heart attack, especially in younger patients.

A new study suggests the damage caused to a person’s heart from years of sedentary behavior can be successfully reversed by the right “dose” of exercise. The study found that exercising four to five times per week can improve heart elasticity as long as the training begins before the age of 65

A ventricular assistive device (VAD) is sometimes used to help pump blood through the ventricle on one side of the heart. There can be problems with conventional VADs, however, which a new soft robotic device may be able to address.
