Women & CVD
Only 13% of women in America believe that CAD and stroke are the greatest health threats to women.
CDC, 2006
6
Women & CVD Facts Nearly 39% of all female deaths occur
from CVD The death rate due to CVD is substantially
higher in African American women than in Caucasian women
38% of women compared to 25% of men will die within 1 year after a heart attack.

ALOHA to Heart Disease
A- Assess your risk
11
Positive Risk Factors for CAD
Family history Hypercholesterolemia Hypertension Cigarette smoking Impaired fasting glucose Obesity Physical inactivity

Quiz
Holly, 42 years old MI
Runner Non-smoker Non-HT Low cholesterol

Daily Physical Activity (PA)
Every U.S. adult should accumulate 30 min or moreof moderate-intensity physical activity on most,
preferably all, days of the week.(U.S Surgeon General, CDC, ACSM)

Coronary Artery Disease (CAD)
Normal?
Coronary Artery Disease (CAD)
AtherosclerosisNormal
19
CAD (con’t)
20
CAD (con’t)
Atherosclerosis Plaque narrows coronary arteries Results in ischemia Leads to myocardial infarction (MI)
21
Thrombosis of Coronary Artery
CAD (con’t)
MyocardialInfarction
Myocardial Infarction (MI)
24
MI Signs
Severe chest pain/pressure Sweating, nausea, vomiting cardiac enzymes ECG changes
25
The Female Heart
26
What’s your diagnosis?
Stella, aged 68 Symptoms
Sleep disturbance Unexplained fatigue SOB Indigestion/nausea Pain in back and high chest
27
The Female Heart 38.2 million women
have CVD Silent MI more
common Atypical chest pain Delayed diagnosis Underutilized
prevention & research
28
Female Heart (con’t)
45 million women older than 50 yr
Smoking cessation rates declining slower than among men
Abdominal obesity 3-7x in CAD risk if
diabetic
More visceralabdominal fat(light) = greaterhealth risk

Take-Home Message Women have worse prognosis and die
more often than men after MI or bypass CAD is largely preventable Major emphasis on lifestyle
modifications: smoking cessation, regular PA, maintenance of healthy weight, lipid lowering therapy
