Heart disease remains the leading cause of death for men in the United States, accounting for roughly 1 in every 4 male deaths, according to the CDC.[1] Men also tend to develop cardiovascular disease earlier than women — often by 7 to 10 years — making it a critical health priority from midlife onward.

Most people know the headline risk factors: high cholesterol, high blood pressure, smoking. But research increasingly highlights a set of significant risk factors that receive far less attention — yet contribute meaningfully to cardiovascular events. Understanding these can reshape how men think about prevention.

Key Takeaways

  • Heart disease is the leading cause of death in American men, and it often develops a decade earlier than in women.
  • Beyond classic risk factors, inflammation (measured by hs-CRP), insulin resistance, and visceral fat are increasingly recognized as major contributors.
  • Lipoprotein(a) — a genetic, often-untested cholesterol particle — affects ~20% of people and significantly elevates cardiovascular risk.
  • Chronic stress, poor sleep, and untreated sleep apnea are independent cardiovascular risk factors that are frequently overlooked.

The Classic Risk Factors (Briefly)

The traditional, well-established modifiable risk factors remain foundational and should not be downplayed: elevated LDL cholesterol, high blood pressure, smoking, diabetes, physical inactivity, and obesity. The landmark INTERHEART study, which examined heart attack risk across 52 countries, found that nine modifiable factors accounted for over 90% of the risk of a first heart attack.[2] These are the bedrock of prevention. But within and beyond them lie several underappreciated contributors.

Overlooked Factor #1: Chronic Inflammation

Atherosclerosis — the buildup of plaque in arteries — is now understood to be fundamentally an inflammatory process, not simply cholesterol "clogging pipes." High-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, independently predicts cardiovascular events even in people with normal cholesterol levels.

The landmark JUPITER trial demonstrated that statin therapy reduced cardiovascular events in people with normal LDL but elevated hs-CRP — strong evidence that inflammation itself is a treatable cardiovascular risk factor.[3] More recently, the CANTOS trial showed that targeting inflammation directly (with an anti-inflammatory drug, independent of cholesterol) reduced cardiovascular events — confirming inflammation as a causal contributor.[4]

Overlooked Factor #2: Lipoprotein(a)

Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle that is largely genetically determined and unaffected by diet or lifestyle. Elevated Lp(a) affects approximately 20% of the global population and is an independent, causal risk factor for heart attack, stroke, and aortic valve disease.[5]

Critically, Lp(a) is not measured in standard cholesterol panels — it requires a specific test. Major cardiology organizations now recommend measuring Lp(a) at least once in adulthood, particularly for those with a family history of premature heart disease. Many men with strong family histories of "unexplained" early heart attacks have undiagnosed elevated Lp(a).

Worth asking about: If you have a family history of heart attack or stroke before age 55 (men) or 65 (women), discussing an Lp(a) test with your doctor may reveal an important, otherwise-hidden risk factor.

Overlooked Factor #3: Insulin Resistance and Visceral Fat

Insulin resistance — often present years before a diabetes diagnosis — significantly increases cardiovascular risk. Visceral fat (the deep abdominal fat surrounding organs) is metabolically active, secreting inflammatory cytokines and disrupting lipid metabolism in ways that subcutaneous fat does not.

Waist circumference is often a better predictor of cardiovascular risk than BMI. The INTERHEART study found that waist-to-hip ratio was more strongly associated with heart attack risk than BMI across all populations studied.[2] A man can have a "normal" BMI but carry dangerous visceral fat — sometimes called "skinny fat" or TOFI (thin outside, fat inside).

Overlooked Factor #4: Sleep and Chronic Stress

Obstructive sleep apnea (OSA) — common and significantly underdiagnosed in men — is strongly associated with hypertension, arrhythmias, and increased cardiovascular mortality. The repeated drops in oxygen and surges in sympathetic nervous system activity during apnea episodes place chronic strain on the cardiovascular system.[6]

Chronic psychological stress is also an independent cardiovascular risk factor. The INTERHEART study found that chronic stress roughly doubled the risk of heart attack. Mechanisms include elevated cortisol, increased blood pressure, inflammation, and stress-driven behaviors (poor diet, smoking, sedentary behavior).[2]

Know the warning signs: Heart attack symptoms in men commonly include chest pressure or pain, pain radiating to the arm/jaw/back, shortness of breath, cold sweat, and nausea. If you experience these, call 911 immediately — do not wait or drive yourself.

Evidence-Based Prevention

  • Know your numbers — all of them: Beyond standard cholesterol, consider asking about hs-CRP and a one-time Lp(a) test, particularly with a family history.
  • Prioritize visceral fat reduction: Through diet and exercise — waist circumference is a meaningful, trackable metric.
  • Get evaluated for sleep apnea if you snore loudly, wake unrefreshed, or have been observed to stop breathing during sleep.
  • Manage stress as a cardiovascular intervention — not a soft add-on. The biology is real.
  • The Mediterranean diet and regular aerobic exercise remain the most robustly supported lifestyle interventions for cardiovascular health.
