Radishes being cut

Consuming more plant-based foods linked to better heart health

Diets higher in plant foods and lower in animal foods were linked with a lower risk of cardiovascular disease and death.

3D printing customized silicon heart valves

Scientists at ETH Zurich and the South African company Strait Access Technologies are using 3D printing to produce customized silicon heart valves.
Higher iron levels associated with a lower risk of heart disease

Higher iron levels associated with a lower risk of heart disease

The study suggests that higher iron levels associated with a lower risk of high cholesterol levels. It also reduces the risk of arteries becoming furred with a build-up of fatty substances.

Scientists hijack bacteria’s homing ability

Until now, stem cells- taken and grown from patients- have been used to regenerate damaged tissue. And the fascinating is, such treatments also showed...

Heart can be programmed to survive without oxygen

For the first time, scientists at the University of Manchester and University of North Texas have shown that an embryonic living heart can be...
How does heart failure develop in people with chronic kidney disease?

How does heart failure develop in people with chronic kidney disease?

If you have kidney disease, you are more likely to get heart disease. Heart disease is the most common cause of death among people...
How Vitamin D deficiency can cause heart failure?

How Vitamin D deficiency can cause heart failure?

Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated...
Smartphone ECG could be used in A&E to detect serious heart conditions

Smartphone ECG could be used in A&E to detect serious heart conditions

Palpitations make you feel like your heart is beating too hard or too fast, skipping a beat, or fluttering. They can be bothersome or...
Scientists catch heartbeat ‘molecular switch’ in action A single heart muscle cell (at x2000 magnification) : the red calcium indicator lines up precisely between the green stripes, which mark where the muscles’ contractive machinery is anchored. In every heartbeat, the distance between the green bands (which are just 2 micrometres apart, or about 1/40 the thickness of a human hair) reduces by just 10%, so all heart muscle cells need to contract together to pump blood – normal calcium activity is essential for this synchronization (Image credit: Paul Robinson).

Visualising the flow of calcium that makes the heart beat

Scientists at Oxford University have devised a new method that uses protein originally found in marine corals to uncover the effects of genetic errors...
