Healthy habits could prevent thousands of cardiac arrests, study finds

[WORLD] Addressing everyday health and lifestyle habits could significantly reduce the number of cardiac arrests—sudden events where the heart stops beating—according to new research.

The study points to moderate consumption of champagne or white wine, a diet rich in fruit, maintaining a healthy weight, managing blood pressure, and sustaining a positive mood as factors that appear to lower the risk of cardiac arrest.

Researchers analyzed health data from over 15,000 individuals across North America and Europe, highlighting how modifiable lifestyle choices can have a substantial impact on heart health. They estimate that for high-risk groups, a combination of moderate alcohol intake and increased fruit consumption could cut the risk of sudden cardiac arrest by as much as 30%.

Higher levels of education also appeared to offer some protection, according to the study published in the Canadian Journal of Cardiology. In contrast, poor sleep habits and physical inactivity were linked to increased risk.

Experts unaffiliated with the research noted that education often correlates with better access to healthcare and improved health literacy. "Education empowers individuals to make informed lifestyle choices and seek timely medical advice," said Dr. Elena Rodriguez, a cardiologist with the Heart Health Institute. "But addressing broader systemic inequalities is essential for truly effective prevention."

The findings echo prior studies linking lack of sleep and sedentary lifestyles to cardiovascular issues. The American Heart Association reported in 2023 that adults sleeping fewer than six hours per night faced a 20% higher risk of cardiac arrest compared to those getting seven to eight hours. Likewise, insufficient physical activity—defined as less than 150 minutes of moderate exercise per week—was associated with heightened danger.

Despite growing evidence, public understanding remains limited. Many people continue to view cardiac arrest as a sudden, unpreventable event, said lead author Dr. Michael Tan. "Our research reinforces the idea that daily choices matter. Small, sustained changes can significantly influence heart outcomes," he said. He advocates for greater public education on sleep, exercise, and stress reduction to improve prevention.

The study’s authors urged policymakers to invest in preventive strategies, such as subsidizing fitness initiatives and expanding nutritional education programs, as part of a global effort to lessen the toll of cardiac arrests.
