Why Heart Disease Is the Top Health Threat for American Men
Heart disease is the leading cause of death for men in the U.S. Learn the key risk factors, why men face higher risk earlier, and steps to protect your heart.
Key takeaways
- Heart disease is the leading cause of death for men in the U.S., causing about 1 in 4 male deaths.
- Men tend to develop heart disease earlier than women.
- High blood pressure, high LDL cholesterol, smoking, diabetes, and inactivity are major risk factors.
- Most heart disease risk can be reduced through lifestyle changes and, when needed, medication.
Heart disease is the number one killer of men in the United States, responsible for about 1 in every 4 male deaths, according to the CDC. Many men who die suddenly from heart disease had no previous symptoms.
The good news is that heart disease is largely preventable. Knowing your risk factors and taking action can dramatically lower your chances of a heart attack or stroke.
What is heart disease?
"Heart disease" refers to several conditions, but the most common is coronary artery disease (CAD). In CAD, fatty deposits called plaque build up inside the arteries that supply the heart. Over time, these arteries narrow and harden. If a plaque ruptures and a clot forms, it can block blood flow and cause a heart attack.
Why men face higher risk earlier
On average, men develop heart disease about 7 to 10 years earlier than women. Before menopause, estrogen appears to provide women some protection. Men also tend to have:
- Higher rates of smoking and heavy drinking
- More visceral (belly) fat
- Lower rates of preventive care and regular checkups
- Higher rates of untreated high blood pressure
Major risk factors
Risk factors you can manage
- High blood pressure: a leading cause of heart attack and stroke. See understanding your numbers.
- High LDL cholesterol: contributes directly to plaque buildup. Learn more in cholesterol explained.
- Smoking and vaping: damages blood vessels and greatly raises risk.
- Type 2 diabetes: high blood sugar damages arteries over time.
- Obesity, especially excess abdominal fat
- Physical inactivity
- Unhealthy diet: high in sodium, saturated fat, added sugars, and processed foods
- Heavy alcohol use
- Poor sleep and untreated sleep apnea
- Chronic stress
Risk factors you can't change
- Older age (risk rises after 45 for men)
- Family history of early heart disease (father or brother diagnosed before 55, or mother or sister before 65)
- Race and ethnicity (for example, Black men have higher rates of high blood pressure)
Life's Essential 8
The American Heart Association's Life's Essential 8 framework highlights eight key measures of heart health:
- Eat better: focus on whole foods, fruits, vegetables, whole grains, lean proteins, and healthy fats
- Be more active: aim for 150 minutes of moderate activity per week
- Quit tobacco: including vaping
- Get healthy sleep: 7 to 9 hours for most adults
- Manage weight
- Control cholesterol
- Manage blood sugar
- Manage blood pressure
Improving even one or two of these factors can meaningfully lower your risk. The more you improve, the greater the benefit.
Practical steps to protect your heart
- Get a checkup and know your blood pressure, cholesterol, blood sugar, and waist size. See our men's checkup guide.
- Move every day: brisk walking counts. Add strength training twice a week.
- Follow a heart-healthy diet and cut back on sodium.
- Quit smoking: call 1-800-QUIT-NOW for free support.
- Limit alcohol to no more than 2 drinks a day, and less is better.
- Manage stress and protect your sleep.
- Take medications as prescribed for blood pressure, cholesterol, or diabetes.
Erectile dysfunction as an early warning sign
Erectile dysfunction (ED) can be an early sign of heart disease, because the small blood vessels in the penis may show damage before larger arteries in the heart. Men with ED, especially at younger ages, should talk with their doctor about heart health.
Know the warning signs of a heart attack
- Chest pain, pressure, or discomfort
- Pain in the arms, back, neck, jaw, or stomach
- Shortness of breath
- Cold sweat, nausea, or lightheadedness
If you experience these symptoms, call 911 immediately. Don't drive yourself to the hospital. Learn more in our heart attack warning signs guide.
The bottom line
Heart disease is the top health threat for American men, but much of it can be prevented. Know your numbers, make heart-healthy choices daily, and partner with your doctor. Small changes now can add years to your life.
