What is Women’s health?
• More than gynecological needs
• More than breast cancer evaluation
• More than obstetrical needs

Update on New Risk Indicators
for Cardiac Disease:• New indicators:
• Age, Sex, BP, Smoking, Family Hx.,
cholesterol
• = composite risk score (such as
Framingham)
• Pregnancy related HT /DM
• HOPE 3 POPULATION….

Most heart attacks aren’t
sudden…they take many years of
preparation!
![Page 10: Dyslipidemia and the Postmenopausal Woman: Calculating ... · Prospective meta-analysis: 90,056 participants in 14 randomized statin trials • For each 1 mmol/L (38 mg/dl) LDL-C](https://reader034.fdocuments.net/reader034/viewer/2022051920/600d7d3bf10c1d69245d1616/html5/thumbnails/10.jpg)
Risk Assessment…A Case:
• Mrs. Smith– 56 year old retired teacher
• PMH borderline HT treated with HCTZ
• + Fam Hx. Brother heart attack age 54
• still smoking despite attempts to quit
– Annual Exam includes cardiac risk assesment
• mild symptoms of menopause, otherwise no complaints
– O/E HR 72 BP 140/70 waist circ. 88 cm
• Normal exam
• T. Chol: 6.2 (235mg/dl) , HDL: 1.22 (47mg/dl), LDL 3.4
(129 mg/dl)

And double that for family history!!!!

CV Risk Reduction in Women -
summary:• CVD is a leading cause of female death
• Risk is underestimated in PM women – to
sort this out use proven risk assessment
tools
• High BP and DM in pregnancy puts women
at future risk
• Women at moderate Risk – 65+ with another
risk benefit from statin therapy.
• Lipid lowering under prescibed in PM women
