But scientists do not know if bad weather on its own is the culprit. We might simply engage in activities that result in more heart attacks, such as shovelling snow.

People who are lonely and isolated have more heart problems as compared to their more social peers. But the reasons behind this might be different than you think.

Although, its diameter is less than that of a matchstick it is able to provide surgeons with more information than ever before.

We have checked out a common myth regarding the heart, and the answer is not as simple as you might think.

Children born with a hole in the wall between heart chambers are often viewed as sickly or feeble. But a new study shows that kids with this relatively common congenital heart defect are just as healthy as other children. A researcher claims we are doing them a disservice by pathologising them.

Scientists have mapped the enzyme that transforms dopamine into noradrenaline. The discovery may lead to better treatment options for diseases such as depression, schizophrenia, and high blood pressure.

Cholesterol is far better than its bad reputation. Good HDL cholesterol can actually limit atherosclerosis.

Every heart is unique. Cardiologists and engineers have teamed up to simulate the structure and blood flow of patients’ hearts using ultrasound and modern software. This can raise the success rate of surgical procedures.

Patients who have relatively high concentrations of secretoneurin in their blood run higher risks of a premature death. But this compound might be just what can save patients in the future.

Scientists find no link between irregular heartbeats and coffee consumption--even if you drink six cups a day.
