The Heart

More people suffer from heart attacks in bad weather: study

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.

Loneliness and isolation can affect your heart

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.

Heart monitoring using microsensors

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

Does a heart stop after a certain number of beats?

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

Live normally despite a hole in heart

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.

Breakthrough for depression, schizophrenia, and high blood pressure

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.

Good cholesterol is getting even better

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

Digital models of individual patients’ hearts help optimise surgery

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.

Peptide found that predicts heart failure

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.

High coffee consumption will not hurt you

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