Recent research indicates that young men should begin considering their heart health much earlier than previously thought. A study led by researchers at Northwestern Medicine, published in the Journal of the American Heart Association, reveals that men may start to develop cardiovascular disease (CVD) in their mid-30s, significantly earlier than women. This insight challenges the common perception that heart disease primarily affects older adults.
The findings stem from the Coronary Artery Risk Development in Young Adults (CARDIA) study, which has followed 5,115 Black and White men and women aged 18 to 30 since 1985 and 1986. None of the participants had cardiovascular disease at the outset of the study. Over the next three decades, researchers conducted follow-up visits every two to five years, monitoring vital heart health markers such as blood pressure and cholesterol levels.
Lead author Alexa Freedman, an epidemiologist and assistant professor at Northwestern University Feinberg School of Medicine, noted, “This allowed us to evaluate when CVD risk emerges—and how it differs between men and women.” The study found that by age 35, men are nearly twice as likely to develop CVD within the following decade compared to women. This disparity in risk persists into midlife, with implications for preventive health measures.
At age 50, the study reported that 4.7 percent of men had developed CVD, while only 2.9 percent of women had reached that level of risk by age 57. Specifically for coronary heart disease (CHD), 2.5 percent of men had developed it by age 50, compared to just 0.9 percent of women, who took approximately ten years longer to experience similar rates.
Despite comparable stroke risks by age 50, other heart-related concerns emerged earlier for men. The research indicates that men remain at a significantly higher risk for heart-related events well into their 50s. While women also face increased risks with age, their heart disease risk escalates more rapidly post-menopause.
The study also assessed various risk factors including smoking, high blood pressure, and Type 2 diabetes. Notably, the gap in CVD risk between genders persisted even after adjusting for these factors, suggesting that existing risk assessments may not fully capture the nuances of cardiovascular health.
Cardiologist Srihari S. Naidu from New York Medical College emphasized, “We already knew that the risk of getting heart disease is higher among men,” but this study clarifies just how early that risk begins to materialize.
Researchers acknowledged that the relatively young age of some participants at the end of the follow-up limited their ability to fully assess long-term sex differences, particularly after menopause, when women’s CVD risk can increase dramatically. Women generally see a rapid rise in CHD risk around age 55, with those experiencing early menopause facing a 40 percent increased risk over their lifetime compared to their peers.
Current cardiovascular disease screenings typically focus on adults over 40, but Freedman advocates for earlier assessments. “Our results suggest that it may also be important to assess CVD risk in young adulthood,” she stated.
Healthcare professionals share this sentiment. Laxmi Mehta, a noninvasive cardiologist at the Ohio State University Wexner Medical Center, remarked, “Age is not protective.” She warns that clinicians must not overlook the critical window for risk prevention in younger patients, regardless of gender.
Many physicians may rely on traditional risk calculators designed for older adults, which often overlook nontraditional factors such as autoimmune conditions and adverse pregnancy outcomes. Certain pregnancy complications, such as gestational diabetes or preeclampsia, have been linked to heightened heart disease risk later in life. Additionally, elevated levels of lipoprotein(a), a genetically inherited cholesterol not typically included in standard lipid panels, can contribute to plaque buildup, increasing cardiovascular risk.
Experts believe that considering a broader range of risk factors could help identify potential cardiovascular issues in younger populations before symptoms arise. Roy Ziegelstein, a cardiologist at Johns Hopkins University School of Medicine, remarked, “Identifying and controlling risk factors is important for everyone.”
It is crucial for individuals in their 30s and beyond to adopt lifestyle choices that reduce heart disease risk. Mehta recommends following the American Heart Association’s Life’s Essential 8 guidelines, which emphasize key health behaviors. Furthermore, mental health factors such as social isolation and depression also play significant roles in adherence to lifestyle changes and medical treatments.
As the study illustrates, proactive measures regarding heart health should not be an afterthought. The message is clear: individuals should prioritize heart disease risk reduction as an integral part of their daily routines from an early age. Regular check-ups starting around age 30 can help individuals assess their family history and other crucial risk factors. Taking action now can pave the way for healthier hearts in the future.
