Do marathon can kill?

The irony: player dies after running a marathon . In 2009, four runners died during half marathon in San Jose and Detroit, and last year, two runners died at the Philadelphia Marathon : one at the finish line, and the other about a quarter-mile from the end of the race. Doctors estimated that the cause of death in all these players was a sudden heart attack.   http://diseaselessreview.soup.io/post/435496517/Online-Diseaseless-Program-Review-Treatment-Yellowing-Jaundice

In a recent study published in the New England Journal of Medicine, researchers analyzed heart attacks among athletes 10900000 marathons in the years from 2000 to 2010 and found that such long runs, in fact, does not lead to increased risk of heart attack .    http://kendrew-diseaselesspro.blogspot.com/2014/06/diseaseless-program-review-heart.html

  In fact, the risk of a heart attack during a marathon turned out to be relatively low, and even lower than the risk of heart attack and death while participating in college sports, triathlon or even while jogging. With 10.9 million riders a marathon in 59 diagnosed

 with cardiac arrest during a marathon or an hour after him. 42 riders died. This means that one died for 259,000 participants (compared to 1 in 52,630 die triathlon participants).   http://diseaselessprograms.mee.nu/diseaseless_program_-_appearance_of_scalp_hair_at_birth
The researchers, led by Dr. Aaron Baggish, director of program performance Cardiovascular at Massachusetts General Hospital, found that those marathon runners who have had a heart attack or died of a heart attack, often suffered from heart disease .

  many of them had thickened walls of the heart and hypertrophic cardiomyopathy, in which the heart muscle becomes enlarged and less flexible,   http://diseaselessreview.soup.io/post/435506993/Ken-Drew-amp-Dr-Patel-Program-Fungal

  so that the heart is pumping blood harder. these conditions may worsen if patients undertake vigorous exercise, which represent an additional burden on the heart.
