| Frequently Asked Questions about Heart Disease in Women |
How many women develop heart disease in the US? Today eight million women are living with heart disease. One of every 2.5 women will die of heart disease or stroke compared to one in 30 who will die of breast cancer.
Do some ethnic groups have a higher risk? Yes, some do. The African American woman has the greatest comparative risk. The incidence of heart and blood vessel disease is as much as 72% higher in African American women as white women. This is due to genetics and the higher incidence of hypertension or high blood pressure. African American women are twice as likely as whites to have a heart attack between the ages of 55 and 65. Hispanic women have a much greater risk of diabetes, and diabetes is now a heart disease equivalent, meaning if you have diabetes it is considered the same risk as already having heart and blood vessel disease. The incidence of heart attack is twice as high in women with diabetes. This is frightening information but there is good news also. What are other risk factors associated with heart disease? We have talked about some of the unmodifiable risk such as gender, age and race. We have not talked about family history but a heart attack in a female relative (mother or sister) under 65 and a male relative (father or brother) under 55 are significant risk factors. The modifiable risks or those things we can change are many. What about modifiable risk factors? These modifications apply to both women and men.
What about non-modifiable risk factors? One of these is age. As women get older our risk for heart disease increases. Post-menopause our risk rapidly catches up to men. As we discussed earlier we have a 10% chance of developing heart disease after 45 years of age and 25% after the age of 65. Secondly, our family history is very important. We inherit our cholesterol profile, (although it is somewhat modifiable), and our tendancy for heart disease is influenced by the inherited factors predisposing us to diabetes and high blood pressure. If we look at our parents and siblings we can see ourselves. Many of the other risk factors we cannot blame on anyone but ourselves - weight, eating habits, smoking and exercise pattern. What about C-reactive protein and homocysteine levels? The C-reactive protein is a "marker" for inflammation. T his is a blood test that measures a protein produced by the liver in response to inflammation somewhere in the body. It is not a specific test for the heart. It has been used to monitor therapy for inflammatory diseases in the past, like rheumatoid arthritis, lupus and vasculitis. Recently it is being promoted as a test for inflammation in the blood vessels. These levels are known to be elevated in heart attack victims and some suggest it may be a marker for an upcoming heart attack. Again the test is not specific for the heart or blood vessels yet, there are other tests being developed that will help us to better distinguish between infammation in the cholesterol plaque of the arteries. and that will be a more helpful test. Elevation of this level (above 0.6 mg/dl) is considered by many to be another risk factor for heart disease. Homocysteine is a normal by-product of the breakdown of an amino acid, methionine, a protein in our diets. For people with abnormally high levels there is an increased chance of blood clot formation and blood vessel wall irritation and breakdown. This predisposes the vessel to collection of cholesterol in the wall. This can be treated successfully in about half the persons with elevated levels by using high dose B-vitamins, B-6, folic acid and B-12, availabe by prescription in tablet form. This level and response is measured with a blood test. Where can I get more information? You can call the American Heart Association Go Red for Women program at 1.800.AHAUSA1 or visit their website.
