• • • EDITORIAL The Yentl Syndrome Bernadine Healy, M. D. N ENGL J MED 1991; 325: 274 -276 Yentl, the 19 th-century heroine of Isaac Bashevis Singer's short story, had to disguise herself as a man to attend school and study the Talmud. Being "just like a man" has historically been a price women have had to pay for equality. Being different from men has meant being second-class and less than equal for most of recorded time and throughout most of the world. It may therefore be sad, but not surprising, that women have all too often been treated less than equally in social relations, political endeavors, business, education, research, and health care.

Problem: Adverse Mortality Gap Resulting in a New Female CVD Majority (National Center for Health Statistics and American Heart Association) Current Strategies Not Working Optimally in Women

Disparities in CVD Treatment for Women • 35, 835 pts with NSTEMI: 41% women • Women had: DM, HTN, age; CAD events Early ASA, heparin, GPIIb-IIIa, ACE-I Revascularizations: CABG 41% Discharge ASA, beta blocker, ACE-I, statins (Four Magic Pills)* • Death, MI, CHF • • * Associated with a 90% reduction in recurrent major adverse cardiac events Blomkalns AL et al. CRUSADE NSTEMI database. J Am Coll Cardiol. 2005; 45: 832 -837.

Sex and Gender Differences in CVD Terminology: • Sex = biological sexual differentiation, (e. g. women have ovaries, men have testes) • Gender = socio-cultural attributes of the biological sex, e. g. women have complex social networks, men have wives

Sex and Gender Differences in CVD More Terminology: • Sex genotype = XX chromosomal makeup, e. g. XX dictates ovarian development of stromal cells in utero. • Sex phenotype = genotype expression given the certain conditions, e. g. premenopausal women higher estrogen levels due to ovulation; postmenopausal women have lower estrogen levels due to no ovulation. Both are XX genotype but differ in phenotypic expression.

Sex and Gender Differences in CVD • Sex differences in perception = women have greater perception (high frequency non-auditory brain testing). Gay men are intermediate between women (higher perception) and men (lower perception), suggesting that this may be genotypic 1 • Sex differences in pain = women have lower thermal pain thresholds compared to men. Thresholds appear mediated by estrogen levels, with higher E 2 levels associated with enhanced pain, suggesting that this may be phenotypic 2 1 Shaywitz et al, Nature 1995; 373: 607; 2 Fillingim et al, Pain Forum 1995; 4: 209

Sex and Gender Differences in CVD • Gender differences in reporting = women are more comfortable discussing feelings with friends and reporting symptoms to physicians 1, possibly due to gender-related acculturation • Gender differences in physician response to symptoms = physicians are more likely to evaluate men compared to women and minorities 2, possibly due to gender-related presentation styles, and/or cultural sexism/racism biases 1 Stoverink J Fam Pract 1996; 43: 567

Sex and Gender Difference in CVD Consequences of Sex and Gender Symptom Issues: • If women perceive chest pain sooner after the onset of ischemia/MI, this will lead to “longer” estimated “ischemia onset” times in the ED, potentially leading to conclusions that “women delay seeking treatment” 1, as well as making more women “ineligible” for thrombolytic therapy. These may contribute to more adverse outcomes. 2 • If women report generally more symptoms suggestive of chest pain, it will be a less effective diagnostic tool, e. g. less specific for epicardial disease 3. This may lead to physician lack of confidence in testing, and may also suggest that chest pain symptoms may be difficult to optimize as a diagnostic tool. 1 Meischke Ann Emerg Med 1993; 22: 1597; 2 Vaccarino, Ann Int Med 2001; 134: 173; 3 Diamond NEJM 1979; 300: 1350

Potential Explanations for Disparities in CVD Treatment in Women • Blame the victim – women do not seek healthcare for symptoms and/or delay seeking attention • Ageism – women are older on average and older patients are less aggressively treated • Sexism (medical judgment) – women are less likely to have and/or die from CAD • Biological sex differences in CVD – women more often present with “female-pattern” disease, which is not recognized compared to “male-pattern” disease

Paradox: Pathophysiological Gender Differences: FRISC II • 749 women and 1, 708 men with unstable coronary artery disease • Entry criteria = symptoms plus ischemia, defined as ECG change or + enzymes • Randomized to early invasive versus noninvasive strategy • Women were older, had fewer prior MI, better LVEF and lower troponin T levels Lagerqvist et al, JACC 2001; 38: 41

What is the Answer? • What is the Problem? • • Lack of patient response to symptoms? Provider sexism (medical judgment)? Ageism? Lack of knowledge and recognition of femalepattern ischemic heart disease resulting in failure to use guidelines therapy?

How to Get Results • Re-name it “Ischemic Heart Disease (IHD) rather than “Coronary Artery Disease (CAD)” • Use a simplified approach to IHD management helps to increase adherence to guidelines • This can be achieved using an ABC format to present important pharmacologic therapies and lifestyle approaches

Know Your ABCs • Antiplatelets/anticoagulants* • Angtiotensin-converting enzyme (ACE) inhibitors/angiotensin-receptor blockers (ARBs)* • Antianginals • Blood pressure control • Beta-blocker* • Cholesterol management (statin)* • Cigarette smoking cessation * 4 Magic Pills

What About Women (and Men) with Female-Pattern Ischemic Heart Disease? • Remember, ACS/angina guidelines are not “cath” based – treat evidence of ischemia and angina, not the cath • Abundant evidence exists documenting lifesaving risk reduction of the 4 magic pills (ASA, ACE, BB, statin) • The power of the prescription pen to implement guidelines therapy preferentially saves women’s lives

Clinical Practice Guidelines • This slide set was adapted from the following 2004 -6 ACC/AHA guidelines: • • • Cardiovascular Disease Prevention in Women 2004, 2007, 2010 Management of Patients With ST-Elevation Myocardial Infarction Management of Patients with Unstable Angina and Non-ST-Segment Elevation Myocardial Infarction Preventing Heart Attack and Death in Patients with Atherosclerotic Cardiovascular Disease Management of Patients with Chronic Stable Angina Update for Coronary Artery Bypass Graft Surgery Evaluation and Management of Chronic Heart Failure in the Adult • • • The full-text guidelines and executive summaries are also available on the ACC and AHA websites at www. acc. org and www. americanheart. org ACC=American College of Cardiology, AHA=American Heart Association

Summary: Women and Heart Disease • Women face a higher mortality from IHD due to their relatively higher prevalence of “female-pattern” ischemic heart disease • Application of guidelines therapy is improving outcomes in women with IHD. • Ongoing work is evaluating mechanisms and interventions directed at sex differences in IHD. • Questions, comments, referrals? merz@cshs. org
