Raise a Glass: How Champagne Could Support Heart Health, According to New Research

Each year, over 356,000 Americans experience sudden cardiac arrest outside of hospital settings, with nearly 90 percent of these incidents proving fatal, as reported by the Sudden Cardiac Arrest Foundation. Sudden cardiac arrest is typically triggered by an irregular heart rhythm that causes the heart to cease functioning, leading to unconsciousness, according to the Mayo Clinic. While maintaining a balanced diet and regular exercise are well-known strategies to mitigate cardiovascular risks, new research suggests that enjoying a glass of champagne could also play a role in preventing sudden cardiac arrest.

A recent study has revealed that consuming champagne might help in the prevention of sudden cardiac arrest, but this benefit is observed only when champagne is consumed at “higher rates.” This finding might seem surprising, given that red wine is often credited with heart health benefits, such as preventing blood clots and reducing LDL cholesterol levels. However, the study highlights that champagne, along with white wine, can be part of a trio of protective factors against sudden cardiac arrest.

Researchers conducted a thorough analysis of 502,094 health records from the UK Biobank and identified 56 modifiable risk factors for sudden cardiac arrest. Over a median follow-up period of 13.8 years, 3,147 individuals experienced sudden cardiac arrest. The identified risk factors were grouped into five categories: lifestyle, psychosocial factors, local environment, physical measures, and socioeconomic status. Risk factors such as high blood pressure, obesity, smoking, poor mental health, inadequate sleep, and excess arm fat were among the adverse examples.

The study’s authors discovered that eliminating risk factors could prevent up to 63 percent of sudden cardiac arrest cases. Specifically, removing the most detrimental one-third of risk factors could avert 40 percent of cases, a measure described as “conservative elimination.” In contrast, a “thorough elimination,” targeting the worst two-thirds of risk factors, could enhance prevention rates to 63 percent.

“We conducted an exposome-wide association study, which examines the relationship between a wide range of environmental exposures and health outcomes,” explained Huihuan Luo, a PhD candidate at China’s Fudan University. “The study found significant associations between various modifiable factors and SCA, with lifestyle changes being the most impactful in preventing cases.”

In addition to reducing risk factors, the study identified protective variables against sudden cardiac arrest, including increased consumption of champagne and white wine. This discovery was highlighted as “one of the most intriguing findings” by researchers in an accompanying editorial.

Nicholas Grubic from the University of Toronto and Dakota Gustafson from Queen’s University in Ontario, Canada, noted that these findings challenge “long-held assumptions about the specificity of red wine’s cardioprotective properties.” They further commented, “Research on the underlying mechanisms remains unclear, but these findings reinforce the idea that the benefits of moderate alcohol consumption may be more complex than previously assumed.”

The study also emphasized other protective factors, such as increased fruit intake, strong mental health, effective weight management, healthy blood pressure, and higher education levels, in reducing the risk of sudden cardiac arrest.
