Marathon och hjärtattack

Nyligen publicerades en studie om hjärtattacker under marathonlopp. Studien visade att det i de flesta fall rörde sig om redan existerande hjärtsjukdomar och att risken att dö i ett lopp är mycket liten.

Här en dock en bloggkommentar som ger några ytterligare detaljer om studien, t.ex.

The average age of the people who survived cardiac events was 53; the average age of the people who died was 34. There are two distinct groups here. One is young people with thick hearts (“hypertrophic cardiomyopathy”), an underlying genetic conditionl; when they collapse, they’re very hard to revive and tend to die. The other is older men with narrowed arteries (coronary artery disease) due to the usual risk factors; when they collapse, they can often be revived if someone gets to them soon enough.
