Age and Years Since Menopause
! Short-term use of HT has no apparent benefit or harm in CHD risk in younger women close to menopause
! Increased risk of stroke (and breast CA) in women closer to menopause
!
Screen for and treat risk factors for CVA before starting HT
! Increased risk of CHD for older women "20 years from menopause, particularly those with vasomotor symptoms
!
Vasomotor sxs
in older women may be a marker of increased CHD risk
Conclusions on HT
! HT should not be initiated (or continued) for the express purpose of preventing cardiovascular disease in either younger or older postmenopausal women
! The current recommendations are that hormone therapy be limited to the treatment of moderate-to-severe menopausal symptoms, with the lowest effective dose used for the shortest duration necessary
Symptoms
! Chest pain is most common symptom in men and women
! Men tend to report chest pain more often
! In women, it’s not always the first or most significant symptom
! Women may experience more transient pain and may have more subtle differences in their description
!
heaviness
!
pressure
!
tightness
!
squeezing
!
sharp
!
stabbing
Symptoms
! SOB
! Nausea/Vomiting
! Transient non-specific chest discomfort
! Arm/shoulder pain, usually left-sided, but more often right sided than men
! Abdominal pain
! Indigestion
! Back pain or pain radiating to the back
! Neck pain
! Jaw pain
! Headache
! Fatigue
! Dizziness
! Loss of appetite
! Palpitations
! Cough
! Women report a greater number of less common symptoms
! Men report more chest pain, diaphoresis, belching, and hiccups
! Although equally likely to have exertional symptoms, more likely to report pain at rest, during sleep, or with mental stress
! Symptoms may be worse during menstrual period
Prodromal Symptoms
! 95% of women report prodromal symptoms
! Average 5 symptoms
! Most common are fatigue (71%), sleep disturbance (49%), SOB (42%), indigestion (40%), and anxiety (36%)
! Only 30% report chest discomfort
! General occur for at least a month prior to event
Non-invasive Testing
! Exercise treadmill testing
!
Lower specificity in women compared with men (higher false positive rate), but slightly higher sensitivity
! Stress echocardiography and nuclear perfusion scan
!
Sensitivity is similar to ETT (~80%), specificity better(~80%)
! CAC with EBCT or MDCT
!
Sensitive, but not specific for significant CAD
!
Radiation. Angio
based on CAC alone not currently recommended
! Cardiac MRI
!
Still not sufficient for coronaries, but may become more useful as a non-invasive study of the coronary microcirculation
Coronary Artery Disease
! Trends apparent across stable angina, unstable angina, NSTEMI, and STEMI
•
older at presentation (~5-10 years)
•
more comorbidities (hypertension, high cholesterol, diabetes)
•

•
more likely to have a history of angina (and more severe)

CABG: Outcomes
! After CABG, women are more likely to be readmitted than men, typically for unstable angina and CHF rather than MI
! Overall, women have similar or better long-term survival than men, but are more likely to have recurrent angina and lower QOL
Humphries et al. J Am Coll Cardiol 2007;49:1552-8Guru et al. Circulation 2006;113:507-16
! The 30 day mortality after CABG decreased significantly from 1991-2004, particularly in women
! Increased use of arterial grafts
Pathophysiology: Non-obstructive CAD
Up to 20% of symptomatic patients presenting for coronary angiography will have no significant coronary artery disease on angiography
While ~60% are women, nearly 40% are men
Pathophysiology
! Women presenting with symptoms suggestive of angina are significantly less likely than men to have angiographic evidence of obstructive CAD
!
Women tend to get more diffuse atherosclerosis
!
Women frequently have evidence of microvascular disease
!
Women frequently have evidence of endothelial dysfunction
!WISE Study (Women’s Ischemic Syndrome Evaluation)

Sex Differences Research
Is there truly a sex difference in
coronary pathophysiology?
Plaque Distribution
! A long, diffuse lesion that is moderately narrowed can cause a similar reduction in distal flow as a short, focal lesion that is severely narrowed
Case
! 60 yo woman
! Hypertension
! Recent presentation to ER with CP, ruled out
! Stress echo: mid-distal anterior and apical ischemia
! Movie Removed
IVUS
! MLA 2.7mm2
! 24-26mm long! Movie Removed
Post-stent
! 2.5 x 28mm Cypher stent
! Post-dilated with a 2.75mm balloon.
! Movie Removed
The Coronary Microcirculation
The resistance vessels are all lined by a single layer of endothelial cells
Microcirculatory Dysfunction
! FFR 0.86
! CFR 1.6
! IMR 35
! Adenosine (endothelium-independent vasodilator) induces hyperemia
! CFR: (normal " 2.5)
hyperemic coronary flow
resting coronary flow
! IMR: (normal < 20)
distal coronary pressure
hyperemic coronary flow
Microcirculatory Dysfunction
IMR: 63 x 0.52 = 32.8
Endothelial Dysfunction
All major cardiac risk factors have been found to associated with endothelial dysfunction in a cumulative fashion.
Endothelial dysfunction is at least partially reversible through risk factor modification.
Case
! 48 yo woman
! No significant risk factors except a 15-pack yr hx of tobacco use 18 years ago
! Low stamina and excessive tachycardia with exercise for the past year
! VO2 stress echo ! anterior ischemia
! Cath lab
!
Normal appearing coronary arteries on angiography
!
Only minimal plaque on IVUS
!
Mild microvascular disease (IMR 23)
!
Tested endothelial function
Endothelial Dysfunction
!Movie Removed
Example Patient
! Started Imdur 30 mg daily
! Decreased max. exertional heart rate from 180s to 160s
! Increased running distance from 0.5 to 2 miles
! Decreased running time from 14 min/ml to 11-12 min/ml
! More energy after work-outs
Sex Differences in Atheroma Burden and Vascular Function Abnormalities
Han et al. Eur
Heart J 2008;29:1359-1369
Summary
! Focus on exercise, weight reduction, avoidance of insulin resistance/diabetes, hypertension, and ! triglycerides and " HDL
! Hormone Therapy: Smallest dose, shortest duration
! Aspirin for 1° prevention of MI or CV death if " 65
! Be attuned to “atypical” symptoms
! Women tend to be older, present later and sicker, have less extensive CAD, have more complications (particularly bleeding), and more recurrent/refractory symptoms
! Post-PCI/Post-MI/Post-CABG!
Standard medical care (ASA, b-blocker, statin, ACE inhibitor, Plavix)!
Continued aggressive risk factor modification!
Rehab (!)!
Depression/Stress
Summary
! Throughout care, treat a woman like a woman (except when we know there’s a benefit to treating her like a man)
