Scientists explain how stressful situations lead to heart attack

Scientists explain how stressful situations lead to heart attackLondon, June 11 - A new study has revealed the hypothetical mechanism behind heart attack caused by stress, emotional shock, or overexertion.

Who should or shouldn't take aspirin to prevent heart attacks revealed

Who should or shouldn't take aspirin to prevent heart attacks revealedWashington, May 10 - Despite aspirin being known to prevent heart attacks and strokes for over 30 years, a new study suggests that it is still unclear as to who exactly should take it daily.

You are most prone to heart attacks, stroke at 6.30 am

You are most prone to heart attacks, stroke at 6.30 amLondon, March 26 : A new study has found that a person is most likely to suffer a heart attack or stroke at 6.30 am.

morning.


New gene linked to heart attack risk identified

New gene linked to heart attack risk identifiedWashington, March 17 - Scientists, including two of Indian origin, have discovered a previously unrecognized gene variation that can help humans maintain healthier lipid levels and cut the risk of heart attack.

The gene, which, according to the US and Norwegian scientists who identified it, was "hiding in plain sight", and had eluded previous hunts for genes that influence cardiovascular risk.


Women at higher risk of heart attacks than men

Women at higher risk of heart attacks than menWashington, Feb 23 - A new study has revealed that there are some significant differences between men's and women's hearts, and these differences may put women at a much higher risk for heart woes than their male counterparts.


Mouthwash users at higher risk of heart attacks

Mouthwash users at higher risk of heart attacksLondon, January 28 - A new study has revealed that mouthwash users are at a greater risk of heart attack, as it can increase blood pressure by killing off "good" bacterias, which help blood vessels to relax.


Deaths higher for heart attack patients at night, weekends

Deaths higher for heart attack patients at night, weekendsNew York, Jan 22 - Heart attack patients who are rushed to hospital during weekends and nights may have higher mortality compared with regular hours.

Mortality is higher, and emergency treatment takes longer, for heart attack patients who arrive at hospital during the night or at weekends compared with regular hours, says a study published on the website of British Medical Journal.


Sunshine reduces BP and cuts risk of heart attack and stroke

Sunshine reduces BP and cuts risk of heart attack and strokeWashington, Jan. 21 - A new study has revealed that exposing skin to sunlight may help to reduce blood pressure and thus cut the risk of heart attack and stroke.

Research carried out at the Universities of Southampton and Edinburgh showed that sunlight alters levels of the small messenger molecule, nitric oxide (NO) in the skin and blood, reducing blood pressure.


Key to healthy heart: Apples

Heart AttackLondon, Dec. 18 - A new research has found that apart from keeping the doctor away, apples can also be effective in preventing heart attacks and strokes in people over 50s.

Study leader at Oxford University, Dr Adam Briggs, said that the research shows how effective small changes in diet can be and that drugs and healthier living can make a real difference in preventing heart disease and stroke, the Daily Express reported.


New breakthrough could help regenerate adult's heart after stroke

New breakthrough could help regenerate adult's heart after strokeWashington, Nov. 20 - Researchers have discovered a new way to dramatically improve heart repair.

The future goal is to use this knowledge to combat human cardiovascular disease by improving repair after a heart attack.

Professor James Martin led the team who uncovered the signaling pathway, called the Hippo pathway, which normally blocks heart repair in adult mice following injury.


Physical fitness could help prevent heart attacks

Physical fitness could help prevent heart attacksWashington, Nov. 18 - Researchers have found that attaining higher levels of physical fitness lowers the risk of having heart attacks and increases survival among those suffering from coronary artery disease, whether or not they have had a procedure to open up their blocked arteries.


Why heart attacks happen in morning

Why heart attacks happen in morningWashington, Nov. 12 - Researchers have found that the internal body clock may contribute to the morning peak in heart attacks and ischemic strokes.

Corresponding author Frank A. J. L. Scheer, PhD, director of the Medical Chronobiology Program at Brigham and Women's Hospital
(BWH), said that their findings suggest that the circadian system, or the internal body clock, contributes to the increased risk for cardiovascular events in the morning.


Flu vaccine halves risk of heart attack in vulnerable patients
