Will Dark Chocolate a Day Keep the Doctor Away?

may additionally 31, 2012 -- have to humans at excessive hazard of coronary heart assault and stroke eat dark chocolate every day?

maybe, in line with a brand new study from Australia.

"dark chocolate can be a pleasing and effective way of turning in essential dietary additives that can offer fitness blessings to the ever growing numbers of human beings at improved threat of cardiovascular ailment," says researcher Christopher M. Reid, PhD, professor of cardiovascular epidemiology and preventive medication at Monash university in Australia.

Reid and his group built a mathematical model to are expecting the long-term health consequences of ingesting dark chocolate day by day in high-risk people. They did no longer observe actual people ingesting actual chocolate.

The researchers also computed whether or not it'd be fee-powerful to spend money on a public schooling marketing campaign approximately dark chocolate's benefits. They observed it might be.

Scientists Explain Stress and Heart Attack Link



June 24, 2014 -- Scientists say they may be able to explain how ongoing stress raises the risk of having a heart attack.

They say stress triggers our bodies to make a surplus of disease-fighting white blood cells. That in turn can boost inflammation in the arteries of people with a condition called atherosclerosis, where the artery walls are thickened by a buildup of plaque.

Stress is a normal part of life, but if left unmanaged it can contribute to health problems including coronary artery disease, high blood pressure, chest pains, or irregular heartbeats.

Inconclusive

Medical research has so far been inconclusive about how stress raises the risk of heart disease. For instance, stress itself might be responsible, or it could be that high levels of stress contribute to other risk factors like high cholesterol or high blood pressure.

Studies have also linked stress to changes in the way blood clots, which raises the risk of a heart attack.

Scientists from Massachusetts General Hospital and Harvard Medical School looked at how stress affected the white blood cell counts of 29 medical workers in a hospital’s intensive care unit after 1 week. This workplace was chosen because of its fast-paced nature, where staff regularly have to make life-or-death decisions.


The authors of the study, published in Nature Medicine, report that when they compared blood samples taken from the volunteers during work to samples taken when off-duty, the white blood cell count was higher in the work samples.

Mice Studies

Next, the scientists exposed mice to stressful conditions by isolating them or tilting their cages until their bodies made excess white blood cells. These mice were already prone to hardening and narrowing of the arteries.

The scientists found that this seemed to trigger plaque inflammation in the arteries of the mice. They say these plaques resembled the way in which excess white blood cells clump together on the inner wall of arteries in humans, where they block circulation or are prone to break off and travel to other parts of the body, potentially triggering a heart attack.

Chest Pain

The British Heart Foundation says there is no evidence to suggest that stress causes coronary heart disease or heart attacks.

Still, it says that anxiety and stress may bring on symptoms like chest pain for people who already have coronary heart disease.

Also, it says the risk of a heart attack for people who are stressed may stem from how they deal with that stress – such as smoking, drinking too much alcohol, and overeating.

Higher BPA Levels, More Heart Disease?

Aug. 15, 2012 -- people who have better ranges of the chemical bisphenol A (BPA) in their urine may be more likely to have narrowing in their coronary arteries, a new study indicates.

BPA has been used for extra than forty years in food packaging, metal meals and beverage can liners, and lots of other products. almost all and sundry has detectable levels of BPA, says researcher David Melzer, MD, PhD, professor of epidemiology and public health at England's university of Exeter.

Melzer's new take a look at suggests an affiliation between urinary BPA stages and the width of the coronary arteries, which deliver blood to the coronary heart.

"The people who had narrowed arteries had higher ranges of BPA in their urine," Melzer says.

The look at, published in PLoS One, does not prove that BPA narrowed each person's arteries. Many factors, which includes food regimen and activity, affect coronary heart fitness.

still, Melzer says, "We need to take it severely that …

Millions of Women Unaware They Have Arterial Disease

Feb. 15, 2012 -- among four million and five million girls within the united states have peripheral artery sickness, or PAD, but few are identified and even fewer receive good enough treatment.

In a unique file released at the midpoint of yankee coronary heart Month, the yankee heart affiliation is looking for greater efforts to pick out and diagnose girls at chance for the condition that typically affects the leg arteries, and is likewise calling for extra ladies to be concerned in PAD research.

a chief purpose is to elevate consciousness approximately a disease that tens of millions of women have, but few know approximately, says university of Minnesota clinical faculty professor of drugs, epidemiology, and network fitness, Alan T. Hirsch, MD, who changed into the lead creator of the assertion.

“The fee of dying and the fitness-care prices related to PAD are at the least akin to the ones of heart ailment and stroke,” he says.
