Patients admitted to hospital with heart problems suffer fewer complications if someone prays for them, according to scientists in the US.

Researchers have cracked the mystery of why eating garlic can help keep the heart healthy.

Hardening of the arteries has been found in Egyptian mummies - suggesting that the risk factors for heart disease may be ancient, researchers say.

Men who do not openly express their anger if they are unfairly treated at work double their risk of a heart attack, Swedish research suggests.

Researchers have used X-ray techniques to uncover the cause of death of a 700-year-old Italian saint. Santa Rosa - who died when she was 18 or 19 years old - was most likely killed by a blood clot in the heart, say the Italian research team.

Heart surgeons are using extreme cooling to allow them to stop a patient's heart long enough to carry out surgery and then revive them.

Doctors have suggested how much garlic they think a person would have to eat each day to gain from its anti-cancer properties - half a clove. It should be served raw to have maximum effect, they said. Previous studies had suggested that a human would have to eat their own weight in garlic before gaining any benefits. But the new research suggests half a raw clove would be enough, rising to four and half cloves if cooked.
