CBS News (2/1, Marcus) reports that research suggests “getting regular exercise not only reduces a person’s risk of heart disease, it can increase the chance of survival if a heart attack does happen, compared to people who aren’t in very good shape.”

TIME (2/1, Park) reports that investigators “studied the electronic health records of more than 2,000 men and women who took a treadmill test as a way to measure how fit they were.” Individuals “with the highest fitness scores were 40% less likely to die after their first heart attack than those with lower fitness scores.” The researchers also found that “a third of the people with the lowest fitness died within a year of their first heart attack.” The findings were published in Mayo Clinic Proceedings.
