Exercise boosts survival after heart attack: study

PARIS: Exercising after a heart attack may help stave off death for longer, Swedish researchers said Thursday.

A study which followed 22,000 heart attack survivors aged 18-74, found that those who boosted their exercise levels after being discharged from hospital, halved their risk of dying within the first four years.

“It is well known that physically active people are less likely to have a heart attack and more likely to live longer,” said Orjan Ekblom of the Swedish School of Sport and Health Sciences. “However, we did not know the impact of exercise on people after a heart attack.”

Ekblom led the research presented at a European Society of Cardiology congress in Ljubljana, Slovenia. The team collected data on heart attack patients in Sweden, and their physical activity levels as reported six to 10 weeks or 12 months after the event.

Researchers documented how many exercise sessions of at least 30 minutes the survivers took part in — with zero to one weekly sessions categorised as “inactive”, and two to seven sessions as “active”.

“All types of activities could be included, typically with an intensity corresponding to a brisk walk or more intense,” Ekblom told AFP.Almost 1,100 of the group of 22,227 died in the four years of the study.
