About one quarter of people who reach age 40 can expect to develop an irregular heartbeat, report researchers according to a recent finding. An irregular heartbeat -- or atrial fibrillation -- is a major risk factor for stroke. An atrial fibrillation causes the heart to quiver, which can lead to pooling and clotting of blood. If a blood clot breaks away and goes to the brain, a stroke results.
In a large clinical trial that followed about 4,000 men and about 4,725 women ,nine hundred and thirty-six of the participants eventually developed atrial fibrillation. Researchers say this translates to about a one in four chance a 40-year-old will end up with an irregular heartbeat. By comparison, the lifetime risk for breast cancer in women is about one in eight.
