WESTPORT 27 (Reuters Health) – According to the August issue of the Heart Journal (Heart) article reported: follicular proliferative phase of the menstrual cycle, estrogen concentration at a low level state premenopausal coronary heart disease women more likely to induce myocardial ischemia. Dr. Guy W. Lloyd, and his colleagues believe that this finding may have an important role in coronary heart disease women timely evaluation and treatment assessment.
Researchers at St. Thomas Hospital in London, nine premenopausal women with a history of coronary heart disease. They allow these patients to check and myocardial ischemia ECG exercise test to ST-segment depression appears the 1mm in time as a positive diagnostic criteria. These women’s menstrual cycle is determined by measuring hormone concentrations.
The research team found that the early follicular hyperplasia, when estradiol and progesterone levels are at a low level, the worst performance of the ECG exercise test, from the beginning of the test to the angina attack time is 290 seconds.
Lloyd the Dr.’s group also found that, at a high level in the hormone concentrations midcycle, ECG exercise test of the best scores for 418 seconds. They also found that the progesterone concentration does not affect the test results.
Based on these results, Lloyd, Ph.D., and colleagues, the women explain premenopausal angina symptoms and ECG exercise test should be taken into account when the menstrual cycle angina.
