Heart damage after heart attack

| July 5, 2015

In 2005, 382,000 people completed a marathon in the United States, an increase of more than 80,000 in 2000, according to marathonguide.com. Mathematically, the risk is very small: Runner dying from a heart attack during the marathon is about 1 in 50,000.

But not racing 42 km put a heart in danger?

Let's look for a new study published in the November 28, 2006 issue of Circulation, a journal of the American Heart Association.

60 participants (41 men, 19 women) in 2004 and 2005 Boston Marathon were tested before and after the race. Each was given an echocardiogram (ECG) to find abnormalities in heart rhythm and was checked for blood markers of cardiac problems, in particular for troponin, a protein found in cardiac muscle cells.

If the heart is traumatized, troponin can show blood. Its presence can determine whether there has been damage from a heart attack.

Runners had normal cardiac function before the marathon, with no signs of troponin in the blood. 20 minutes after, 60 percent of the group had elevated troponin levels, and 40 percent had levels high enough to indicate the destruction of heart muscle cells. The

Also had significant changes in heart rhythm. Those who have given less than 56 km per week led to the race, he had the highest levels of troponin and the most pronounced changes in heart rhythm.

None reported chest pains or shortness of breath on arrival. All felt good.

Few days abnormalities disappeared. But something seems to have happened in the race. Their hearts seem to have been stunned and race has an effect on cardiac muscles.

However, marathons may present an opportunity for silent symptomless heart disease to suddenly insert. Pulsing excitement, adrenaline and unpleasant process of hitting the wall can trigger physiological changes that loosen arterial plaques, precipitating a heart attack. The advice given

Runners with heart problems is to train for the race, reaping the benefits of exercise cardiac resistance, and then watch the event on television. Anyone

Marathon accession should undergo a full medical screening, with a visit to a cardiologist for over 40 years, and are covered by insurance if recommended by a doctor. Those with a family history of heart problems should be especially cautious.

However, it is still too early to draw any conclusions. According to the researcher, more bodies piling up if there will be real persistent long-term cardiac damage.

General, the evidence is strongly in favor of the idea that endurance exercise is still useful in terms of heart health. The most trusted Doctor Reveals … How
