Abstract:
Objective To explore the influencing factors of false positive in treadmill exercise test.
Methods 222 treadmill exercise testing positive patients who were undergone coronary angiography within 1 month were studied. Patients were divided into two groups: coronary heart disease group (CHD group, n=143) and non coronary heart disease group (non CHD group, n=79). Clinical manifestations, combined diseases, coronary arteries situations, ultracardiography and treadmill exercise testing datas of these patients were collected and analyzed.
Results Female gender (P=0.003, OR=11.112, 95%CI 2.258-54.784), age (P=0.016, OR=0.916, 95%CI 0.854-0.984), Bruce level (P=0.006, OR=3.453, 95%CI 1.424-8.373) and ejective fraction (P=0.029, OR=1.103, 95%CI 1.010-1.204) were independent influencing factors of treadmill exercise testing false positive.
Conclusion Female gender, age, Bruce level and ejective fraction were independent influencing factors of treadmill exercise testing false positive. Meanwhile other atherosclerosis risk factors and parameters of exercise testing (besides Bruce level) could not provided reference to the judgement of false positive.
