Gender differences : Coronary Artery disease
- Gender differences
- Coronary Artery disease
- Men
- First heart event for men is more often Ml than angina.
- Men report more typical signs and symptoms of angina and MI.
- Men receive more evidence-based therapies (e.g., aspirin, statins, diagnostic catheterization, PCI) when acutely ill from CAD (e.g., MI) than women.
- Mortality rates from CAD have decreased more rapidly for men than women.
- Women
- Women experience the onset of heart disease approximately 10 years later than men.
- CAD is the leading cause of death for women, regardless of race or ethnicity.
- More women with MI (compared to men with MI) die of sudden cardiac death before reaching the hospital.
- Before menopause, women have higher HDL cholesterol levels and lower
- LDL cholesterol levels than men. After menopause LDL levels increase.
- Acute coronary syndrome
- Men
- After age 75, the incidence of MI in men and women equalizes.
- Men present more frequently than women with an acute MI as the first manifestation of CAD.
- Men develop greater collateral circulation than women.
- Men have larger-diameter coronary arteries than women.
- Vessel diameter is inversely related to risk of restenosis after interventions.
- Standard screening for risk of sudden cardiac death (e.g., EP studies) is more predictive in men.
- Women
- Women are older than men when seen with first MI and often have more co-morbidities.
- Women seek medical care later in the CAD process and often are more ill on presentation than men.
- First heart event for women is more often unstable angina than MI.
- Once a woman reaches menopause, her risk for an MI quadruples.
- Fewer women than men manifest the “classic” signs and symptoms of UA or MI.
- Fatigue is often the first symptom of ACS in women.
- Women experience more “silent” MIs compared with men.
- Among those who have an MI, women are more likely to suffer a fatal heart event within 1 year than men.
- Women report more disability after a heart event than men.
- Women who have coronary artery bypass graft surgery have a higher mortality rate and more complications after surgery than men.
