The Heart

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.

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.

When science promoted sugar as healthy

Studies in the 1970s showed that people couldn’t get overweight or develop cardiovascular diseases from consumption of carbohydrates such as sugar. A Norwegian professor thinks we are still paying for this mistake.

How different are we on the inside?

We vary quite a lot on the inside and that can be a blessing. For instance, if you have a large liver you can save more than one life.
