Dr. Trent's seed grant study will examine the effect of a new type of blood test that measures signs of a heart attack. This new blood test called a high-sensitivity troponin is more precise and can measure lower levels of circulating troponin in the blood stream than previous tests. With this new test, it is now known that women have lower levels of circulating troponin in the blood stream than men. As a result, this new test can better identify heart attacks in women when compared to the older test. Consequently, in this study, we will evaluate how this new test changes the percentage of women diagnosed with a heart attack and how cardiac risk scores in women change with the addition of this new test.
