Unhealthy Lifestyle Choices Raise Heart Disease Risk Significantly for Women

Recent research underscores that specific lifestyle and health factors can substantially elevate the risk of heart disease in women, even more so than in men. Evidence from a study conducted by Sunnybrook Health Sciences Centre in Toronto reveals that eight unhealthy habits amplify heart health risks for women to a greater extent than for their male counterparts.

Understanding the Key Risk Factors

The eight lifestyle habits identified include diet, sleep patterns, physical activity levels, smoking, body mass index, blood glucose levels, lipid profiles, and blood pressure. According to the study, these factors combined can nearly double the risk of heart disease for women compared to men.

Details of the study will be unveiled at the American College of Cardiology’s Annual Scientific Session, taking place in Chicago from March 29 to March 31, 2025.

Study Background and Methodology

Researchers analyzed data from over 175,000 Canadian adults participating in the Ontario Health Study between the years 2009 and 2017. The participants had no preexisting heart conditions at the onset of the study.

The research team assessed individual scores based on the eight identified risk factors and monitored the occurrence of seven critical heart disease outcomes over an 11-year time frame. Outcomes included heart attack, stroke, unstable angina, peripheral arterial disease, heart failure, coronary revascularization, and cardiovascular mortality.

A Gender Disparity in Heart Health

The results indicated that a greater percentage of women maintained ideal health compared to men (9.1% women versus 4.8% men). Conversely, a higher proportion of men exhibited poor health conditions (30.5% men versus 21.9% women).

Alarmingly, women categorized as having poor health were nearly five times more likely to develop heart disease compared to those maintaining optimal health. In contrast, men with poor health had a 2.5 times greater risk than men in good health.

Additionally, among women with intermediate health conditions, there was a 2.3 times heightened risk of heart disease relative to those with ideal health. For men in similar health standings, the risk factor was notably less at 1.6 times.

Dr. Maneesh Sud, the lead author and an interventional cardiologist at Sunnybrook, commented on the implications of these findings. He emphasized that for equal levels of health, women exhibit a greater increase in risk based on the same factors when compared to men.

Potential Reasons Behind the Increased Risk

Dr. Sud also pointed out that women, despite generally being healthier than men, respond differently to various health risks, impacting their outcomes significantly. This distinction demonstrates that heart health assessments should not adopt a one-size-fits-all approach.

Novel Findings in Heart Disease Research

This significant gender disparity in heart disease risk, particularly in relation to lifestyle factors, marks a noteworthy observation not reported in previous studies. The implications suggest that gender-specific screening and risk assessment mechanisms could improve predictions of heart disease susceptibility.

Expert Opinions on Women’s Heart Health

Dr. Marc Siegel, a clinical professor of medicine and senior medical analyst at NYU Langone Health, provided insight into these findings. Although he was not part of the research team, he explained that certain life milestones unique to women – such as pregnancy, childbirth, and menopause – may contribute to their increased susceptibility to heart disease.

He noted that estrogen can provide some protection against cardiac issues but drops significantly during menopause, coinciding with an increase in cholesterol and body weight. This hormonal interplay could heighten risks for women as they age.

Interestingly, while premenopausal women generally experience lower cardiovascular risk, this situation changes post-menopause, often leading to higher incidences of heart disease.

The Need for Further Research

Dr. Bradley Serwer, a cardiologist based in Maryland, emphasized the necessity for focused studies examining cardiovascular risks in women. He has observed that traditional assumptions about heart disease risk factors affecting genders similarly might not hold true.

Serwer remarked that more studies are required to explore whether the differences in heart disease susceptibility between genders are strictly due to hormonal effects, or if other factors contribute. He commended the study’s authors for their valuable work, which challenges existing perspectives on primary prevention methods in women.

Moving Forward with Awareness

As awareness of gender-specific heart health continues to grow, it becomes increasingly critical to integrate new findings into healthcare practices. By tailoring risk assessments and preventive measures to consider these distinct differences, healthcare providers can better serve the unique needs of women. Ultimately, ongoing research remains essential to unravel the complexities surrounding heart disease and its impact on different populations.
