Abstract


Objective: To research treadmill exercise test parameters, and coronary heart disease, and ways of improving the method of female subjects in the activities of the diagnostic value of treadmill exercise test. Methods: analysis of 188 cases worked in the medical records of the line activities, Huashan Hospital treadmill exercise test and coronary angiography by evaluation treadmill test positive results and coronary heart disease correlation. Duke score calculated by treadmill exercise test data (exercise duration -5 × sports or exercise any lead ST segment offset -4 × angina index), systolic blood pressure recovery systolic blood pressure than the end of the (sports 3min after peak exercise systolic blood pressure ratio), observed both with coronary heart disease, especially in women with coronary heart contact. Record the tablet test positive lead, the statistical analysis with a specific coronary lesion is relevant. Results: the treadmill test positive for diagnosing coronary artery disease: sensitivity 69.2%, specificity 54.5%, positive predictive value of 51.9%, negative predictive value of 71.4%; female sensitivity, specificity, and negative predictive values ??were close to the men positive predictive value than men (P = 0.014). The Duke score made positive group crown crown made negative group was -2.25 ± 6.3, 0.75 ± 4.2, P <0.001. Duke score risk groups (≥ 5 low-risk group for coronary heart disease, -10 to 4 in the risk group, ≤ -11 for the high-risk group) and severity of coronary, P <0.001, in men, women exist; same group, male and female populations varying degrees of coronary lesions proportion different female patients with lesions lighter than men. Systolic blood pressure recovery than in the crown made positive group and negative group was 0.88 ± 0.14, 0.83 ± 0.14, P = 0.013, the difference was statistically significant. Treadmill exercise test positive, systolic blood pressure recovery ratio> 0.9 can prompt the presence of coronary heart disease. This prompt value also exists in women. The tablet test positive lead more common in the lower and anterior wall conductivity associated (V4, V5, V6) has nothing to do with the specific lesion (P = 0.911). Conclusion: The classic ST segment treadmill exercise test positive standards for coronary heart disease sensitivity better, more limited specificity and positive predictive value, the positive predictive value in women, especially low. Duke score and risk classification of the severity of coronary better predictive value. Treadmill test positive population, systolic blood pressure recovery ratio> 0.9 contribute to the diagnosis of coronary heart disease. Women, the use of the the Duke score danger packet and and further reference systolic blood pressure recovery than the same help to diagnose coronary heart disease. Activities the tablet test positive lead and the lesion does not necessarily correspond to the relationship.
