Prevalence of CAD in Women
• Coronary Artery Disease is the leading cause of death in Women.
• CAD mortality is higher in Women than Men.
• Impact of obesity is greater in Women than in Men.
• Incidence of CAD lags 10 years behind Men.
• Consequences of CAD are worse in Women than in Men.

• Pathophysiology of CAD is different in Women.
• Women have smaller Coronary Arteries.
• Less obstructive CAD.
• Disorders of the micro vasculative and Endothelial dysfunction have been implicated in Women.
• Women have a greater frequency of plaque erosion and distal embolization.

Diagnosis of Myocardial Ischemia in Women
A negative exercise test is a good negative predictor of CAD in Women.

Management of Obstructive CAD in Women
Why is mortality due ACS in Women higher than in Women?
1. Women are treated less aggressively than men.
2. Receive less EB medicine.

Management of Non-Obstructive CAD
Women with myocardial ischemia and non-obstructive CAD, the prognosis was felt to be benign in the past.
More recent data has shown that the prognosis is not benign and the risk of CV events is higher than for asymptomatic women.

In the WISE Study:- Symptomatic women with non-obstructive CAD had an event rate of 16% vs 7.9% in Symptomatic women with no CAD and event rate was 2.4% in asymptomatic controls.

Treatment of Non-Obstructive CAD
1. Improve Endothelial function with Statins and ACE Inhibitors.
2. Symptoms with Beta Blockers and Imipranine and L arginine.
3. Ranolazine is promising.

19
Undertreatment of CAD • Women are still less likely to receive
preventive recommendations, such as lipid lowering, ASA, life style modification.
• Hypertensive women are less likely to have their BP at goal.
• Dyslipidemic women are less likely to reach their LDL goals, (particularly diabetic women).
• Women receive less cardiac rehabilitation.

After adjustment for Age, HR, DM, HTM, GRACE Risk Score: Female gender comes associated with increased in hospital mortality. Under use of EB therapies was also associated with increased mortality.

This is the 1st study from the Middle East to show that Women with ACS had a high mortality rate
compared to men, after adjustment of all co-founders.

It confirms previous studies that women have different risk profiles :-
Present late Atypical symptoms Longer door-to-needle times Less perfusion therapies

Recognition of gender differences will lead to a number of quality
improvement projects to improve the process of care.
Physician and public awareness
programs are important to improve the management of women with ACS.

Gulf RACE II
Women are treated more conservatively. This may have been due to the following:
1. More co-morbidities
2. Atypical presentation
3. Patient preference
4. Physicians preference or Fear

Gulf RACE II
In this Study, in contrast to Gulf RACE I, the Multivariate Regression Models indicated that most of the differences in mortality can be explained by the confounding baseline variables and the differences in management.
Greater awareness of CAD in Women may eliminate the gender gap.

Menopausal Hormone Therapy, SERMs and CVD: Summary of Major Randomized Trials
Use of estrogen plus progestin associated with a small but significant risk of CHD and stroke
Use of estrogen without progestin associated with a small but significant risk of stroke
Use of all hormone preparations should be limited to short term menopausal symptom relief
Use of a selective estrogen receptor modulator (raloxifene) does not affect risk of CHD or stroke, but is associated with an increased risk of fatal stroke

HEART DISEASE IN WOMEN Summary
1. Less obstructive CAD. 2. More chest pain without obstructive CAD. 3. Symptoms do not correlate with severity of
stenoses. 4. Young and middle aged women show high
rates of adverse outcomes after MI.

Women do worse than men when they have an STEMI.
Sex differences are found in younger women with MI.
These women have a higher rate of risk factors and co-morbidities compared to men.

Sex differences in EB medications are significant.
There are larger differences in reperfusion therapy.
Also differences in catheterization and revascularization.
