LOS ANGELES — Sudden cardiac arrest (SCA) remains one of the deadliest medical emergencies in the United States, claiming over 436,000 lives annually. But new research suggests that certain lifestyle factors — including the moderate consumption of champagne and white wine — may help reduce the risk.
Published in the Canadian Journal of Cardiology, the study analyzed health data from over 500,000 individuals in the United Kingdom and identified 56 modifiable risk factors associated with SCA. The findings underscore the powerful role that lifestyle choices may play in preventing this often-fatal condition.
Surprising Heart Health Allies: Champagne and White Wine
In an exposome-wide association study, researchers examined a wide range of environmental and behavioral exposures without predefined hypotheses. Through further validation using Mendelian randomization — a method that strengthens causal inferences — they discovered that moderate consumption of champagne or white wine was linked to a lower risk of sudden cardiac arrest.
While red wine has historically been highlighted for its heart health benefits, this study challenges that conventional wisdom. An editorial by cardiovascular experts from the University of Toronto and Queen’s University described the findings as “intriguing,” suggesting alcohol’s effects on heart health may be “more complex than previously assumed.”
Other protective factors identified included higher fruit intake and regular computer use — the latter potentially reflecting greater cognitive engagement or education level.
The Bigger Picture: Preventable Risk
Researchers estimated that 40% to 63% of SCA cases could potentially be prevented through improved health behaviors. Notable risk factors contributing to higher SCA risk included:
- Elevated systolic blood pressure
- High body mass index (BMI)
- Excess arm fat
- Sedentary lifestyle
- Poor sleep quality
- Chronic feelings of discouragement or low mood
- Lower education levels
Conversely, maintaining a healthy weight, eating more fruits, and engaging in regular social and mental activities were linked to a reduced risk.
The study reinforces the notion that lifestyle modification remains one of the most effective tools for preventing sudden cardiac arrest.
Alcohol’s Dual Nature: A Call for Caution
Despite the promising results, experts urge caution. The findings arrive amid an ongoing scientific debate about the risks and benefits of alcohol consumption.
The U.S. Surgeon General has emphasized that any alcohol use can increase cancer risk. Conversely, recent studies suggest that moderate drinking may support brain function and social connectivity — both contributors to cardiovascular health.
Cardiologist Dr. Evan Levine, speaking to the New York Post, warned that even moderate drinking can raise blood pressure and may lead to long-term heart complications. Chronic heavy alcohol use, he noted, can result in alcohol-induced cardiomyopathy — a serious condition that weakens the heart muscle.
In short, while an occasional glass of bubbly may offer some heart benefits, moderation is key.
Looking Ahead
The researchers acknowledged limitations in the study. It did not differentiate between in-hospital and out-of-hospital cardiac arrests and largely reflected data from white, middle-aged, and older adults in the U.K. Further studies are needed to determine whether these associations hold across more diverse populations.
Ultimately, the study highlights the potential of lifestyle interventions — from diet to cognitive engagement — to significantly reduce the risk of sudden cardiac arrest. However, experts stress that alcohol remains a complex variable in health outcomes, and its consumption should be approached with care.
