Men Face Greater Risk of Cardiac Arrest
Heart disease tends to develop earlier than it does in women, researchers say

THURSDAY, June 30, 2016 (HealthDay News) -- Men are significantly more likely to have their heart stop suddenly than women are, a new study finds.
About one in nine men will suffer a cardiac arrest before the age of 70, compared to about one in 30 women. At age 45, men have nearly an 11 percent lifetime risk of sudden cardiac death, compared with a 3 percent risk among women of the same age, researchers report.
"Most of these deaths are occurring prematurely -- before age 70 -- which means that this is a very important and largely preventable cause of death that's really affecting families in a devastating way," said lead researcher Dr. Donald Lloyd-Jones. He is chair of preventive medicine at Northwestern University Feinberg School of Medicine, in Chicago.
About 450,000 Americans die from sudden cardiac death each year, and most never have any symptoms of a heart problem, he said. Men are especially at risk because heart disease tends to develop earlier in men than in women, Lloyd-Jones explained.
"We need to get more serious about screening men for risk factors for cardiac arrest," he said. The major risk factors include smoking, high blood pressure, high cholesterol and diabetes.
"Know your numbers, especially your blood pressure, but also know your cholesterol or whether you have diabetes," he said. "At 50, men should also have a baseline electrocardiogram, which might reveal heart problems."
For the study, Lloyd-Jones and his colleagues examined data on more than 5,200 men and women, aged 28 to 62, who took part in the long-running Framingham Heart Study, which began in 1948.
That study looked at four major risk factors for heart trouble -- blood pressure, cholesterol, smoking and diabetes. None of the participants had a heart problem at the start of the study. Because most of those in the study were white, the findings cannot necessarily be applied to other groups, the researchers cautioned.
Over decades of follow-up, 375 people died from a cardiac arrest. The risk for sudden cardiac death was even higher -- 12 percent -- among men who had two or more risk factors, the researchers found.
