35 & Heart Health: When to See a Cardiologist – New Study

Birmingham, Ala., February 9, 2026 — For men, the clock on heart health may start ticking much earlier than previously thought. A new study reveals significant differences in cardiovascular risk between sexes begin around age 35, suggesting a need for earlier screening and preventative measures.

Men’s Hearts: Why 35 Matters

A decades-long study found men experience a divergence in heart disease risk starting in their mid-30s, reaching key milestones seven to ten years before women.

• Men begin to experience a faster accumulation of heart disease risk factors around age 35.
• This divergence persists even in individuals with healthy lifestyles.
• The study focused on premature cardiovascular disease—events before age 65—including heart attacks, strokes, and heart failure.
• Researchers found no significant difference in stroke risk between men and women, but coronary heart disease risk emerged earlier in men.

You might not expect a check-up with a cardiologist to be on your to-do list at 35. Heart disease often feels like a concern for those decades older. But research published in the Journal of the American Heart Association suggests that for men, this birthday could be a pivotal moment to prioritize cardiovascular health—even if you feel perfectly well.

How Was the Study Conducted?

Researchers analyzed data from the CARDIA (Coronary Artery Risk Development in Young Adults) study, a long-term project initiated in 1985. The study initially enrolled over 5,100 Black and white adults, aged 18 to 30, from Birmingham, Chicago, Minneapolis, and Oakland. Participants were followed for a median of 34 years, with regular assessments of their cardiovascular health, lifestyle, and any heart-related events. This extended follow-up allowed researchers to pinpoint when heart disease risk began to diverge between men and women and whether lifestyle factors played a role.

What Did the Study Find?

The findings confirmed earlier research and added crucial details. By age 50, approximately 5% of men in the study had developed cardiovascular disease—a threshold women didn’t reach until age 57, a full seven years later. When focusing specifically on coronary heart disease (including heart attacks), the gap widened: men reached a 2% incidence rate a full decade before women.

Importantly, researchers discovered that statistically significant differences in 10-year cardiovascular disease event rates first appeared at age 35. This means that by their mid-30s, a man’s risk of developing heart disease over the next decade begins to surpass that of a woman—and this gap continues through middle age.

Interestingly, the study found no significant difference between men and women regarding stroke risk. The most pronounced differences were observed in coronary heart disease, with smaller but notable gaps in heart failure emerging at later ages.

Perhaps surprisingly, the study revealed that even after accounting for factors like blood pressure, cholesterol, blood sugar, body mass index, diet quality, physical activity, and smoking status, men still exhibited a significantly higher risk of cardiovascular disease than women. This suggests that traditional risk factors don’t fully explain why men develop heart disease earlier.

Researchers noted some limitations. Due to the relatively young age of participants at the study’s conclusion, the absolute number of some cardiovascular events (like strokes) was low. The study population consisted only of Black and white participants, potentially limiting the generalizability of the findings. Additionally, sleep—now recognized as an important factor in heart health—wasn’t measured at the study’s outset and couldn’t be fully incorporated into the analysis.

What Does This Mean for You?

If you’re a man approaching or past 35, this study suggests it’s time to take your heart health seriously—even if you feel fine. Consider scheduling a cardiovascular risk assessment with a healthcare provider or a preventive cardiologist, especially if you have a family history of heart disease. Early detection of issues like elevated blood pressure, high cholesterol, or early signs of atherosclerosis (plaque buildup in the arteries) can help you take action before problems develop.

Of course, heart health isn’t solely a concern for men. Cardiovascular disease remains the leading cause of death for women, too, and healthy lifestyle choices benefit everyone. The study also emphasizes that cardiovascular health behaviors matter throughout young adulthood—not just in middle age.

Here are some evidence-backed ways to support heart health through nutrition:

• Embrace a Mediterranean or DASH-style eating pattern. Both emphasize fruits, vegetables, whole grains, legumes, nuts, seeds, and healthy fats like olive oil.
• Eat more fiber. Soluble fiber from oats, beans, lentils, and fruits can help lower LDL (“bad”) cholesterol. Aim for at least 25 to 38 grams of total fiber daily.
• Limit sodium and ultra-processed foods. High sodium intake is linked to elevated blood pressure. Cutting back on packaged snacks, fast food, and processed meats can make a big difference.
• Stay active. Physical activity works hand-in-hand with diet. Aim for at least 150 minutes of moderate-intensity exercise per week.

A new study in the Journal of the American Heart Association reveals that sex differences in cardiovascular disease risk emerge around age 35, with men reaching key heart disease milestones seven to ten years earlier than women. These differences persist even after accounting for lifestyle factors, suggesting men in their mid-30s—particularly those with a family history of heart disease—may benefit from proactive heart health screenings. Prioritizing a heart-healthy diet rich in vegetables, whole grains, healthy fats, and fiber, along with regular physical activity, remains one of the best ways to protect your cardiovascular health at any age.
