History Anatomy Physiology Risk Factors Symptoms Treatments HRT Prevention

HistoryHistory• Heart Disease is the #1 Killer of

women.• 50,000 more women die each

year than men.• In 1995 there were 500,000

deaths related to CVD. 2x that of cancer.

• African American women have a 70% increase in deaths when compared to White women.

• Women not treated as aggressively as men.

Anatomy of CirculationAnatomy of Circulation Right Coronary Artery

Supplies the right ventricle and right atria.

Right Posterior Descending Artery

Supplies the posterior portion of heart(AV node, IV Septum and posterior papillary muscle).

Left Coronary Artery Branches into the anterior descending and

circumflex ,they supply Left Ventricle,anterior papillary muscle and anterior IV septum and left atria.

Women's arteries are 0.5 to 1.0 mm smaller in diameter than those of men.

Physiology of ThrombusPhysiology of Thrombus

Hyperlipedemia contributes to plaque formation.

Arteries most effected are proximal left anterior descending, proximal right coronary artery and the distal right coronary artery

Injury theory, plaque rupture and thrombosis formation cause blockage.

Risk FactorsRisk Factors

Risk Factors That Risk Factors That Can be Treated Or

Cannot Be Changed Changed

Heredity Smoking Diabetes

Gender /Race High Blood Pressure Obesity

Increasing Age Sedentary Life Hyperlipidemia

Unchangeable Risk FactorsUnchangeable Risk Factors

Heredity: The risk increases 2 to 3 fold in patients with a family history of MI and rose with the number of relatives with a history of MI.

Gender: Mortality rate higher in women. 50,000 die annually.

1st heart attacks often fatal. Within 1 year of MI 42% of women die/24% of men. 6 years after 1st MI 33% of women will suffer 2nd MI as opposed to 21% of men. Fewer studies are done with women .

Race: African American Women have an increased mortality rate as opposed to white women, they are more likely to be overweight and also have diabetes and hypertension, independent risk factors.

Treatable Risk FactorsTreatable Risk Factors

Smoking: Decreases estrogen and increases lipids. As few as 4 cigarettes/day can have twice the risk of CAD than non-smokers

High Blood Pressure: Approximately 50% of women have HTN by age 45 and 79% of African American Women respectively. > than 140/90 is determined as HTN.

Sedentary Life: Moderate exercise program can decrease BP and increase HDL and decrease VLDL levels.

Treatable Risk FactorsTreatable Risk Factors

Diabetes: Type II diabetes increases 3 to 7 fold the risk of CAD as opposed to men which is 2 to 3 fold. It also contributes to HTN and hyperlipidemia. More prevalent in African American Women. Increases risk of recurrent MI and heart failure.

Obesity: Maintenance of ideal body weight decreases risk of MI 35%-60%. Increased weight causes increases in lipids, blood pressure and diabetes.

Hyperlipidemia: postmenopausal HDL levels decline and LDL levels rise.

SymptomsSymptoms

Common Symptoms• Chest Pain, heaviness,tightness• Pain in arms• Shortness of Breath

Uncommon Symptoms• Nausea, vomiting, heartburn• Fainting, confusion, sweating• Jaw pain, neck pain, back pain• Fatigue, palpations

Acute Myocardial Infarction Acute Myocardial Infarction TreatmentsTreatments

• Angioplasty• Thrombolytics• ASA• Beta-Blockers• ACE Inhibitors• Gp IIb/IIIa Inhibitors• CABG

It’s What’s inside that

counts

AngioplastyAngioplasty

• PTCA: 1st line of treatment if within 1 hour of infarct.

• Stents: currently have a 30% restenosis rate caused from the injury cascade to the vessel wall.

• Sirolimus-Eluting Stents: new stent just out March 2003. Coated with a immunosupressive drug which prevents cell proliferation in the G1 phase . In recent studies it has shown to decrease the in-stent stenosis by 25%.

• Results: 30 days after stenting women’s death rate or MI was 3.1% as compared to men at 1.8%. The 1 year outcomes were similar for men and women, 5.8% and 6.0% respectively. Women were older had more diabetes, hypertension and hypercholesterolemia.

MedicationsMedications

Thrombolytics: Within in 1 hour of symptoms can reduce mortality by 3.5%. There has been a 17% reduction in the 30 day mortality form 1975-1995.

ASA: The increased use has been the greatest contributor to decreased mortality. In 1975 only 5% usage, 1995 75% usage.

Beta-blockers: Reduces sudden death and reinfarction rate.

ACE Inhibitors: Reduces morbity and mortality in MI survivors and

women with LV dysfunction. GIIb/IIIa Inhibitors: Aggrastat, Integrilin and plavix these are

platelet aggragates which improve outcomes equally in women and men with stent placement.

Coronary Artery Bypass Coronary Artery Bypass GraftingGrafting

• 32% of all surgeries are female.• Higher complications early.

Per/post op period.• More risk factors at time of surgery (HTN, PVD, CHF and Diabetes)• Older at time of surgery• Smaller body size and artery size

difficult anastomoses.• Less relief from Angina symptoms.• Less use of Internal Mammary

Artery, which has better outcomes.• 5 years out no difference in death

rate of both sexes.www.sas.upenn.edu/~lsnyder2/Facts.html

Healthy Diet Weight Loss Exercise Smoking Cessation Monitor Blood Pressure Monitor Lipids Diabetes Control

ConclusionsConclusions

• Increase usage of CV drugs known for heart disease• Increase knowledge of heart disease by women and their

doctors• Early diagnosis of heart disease symptoms• Monitoring for Diabetes, weight management• Monitoring for HTN and lipid profile• Increase usage of Cardiac Rehab programs• Inclusion of Women in more cardiac studies
