Research on the application of exercise echocardiography heartbeat mapping in clinical diagnosis and treatment of coronary heart disease in the elderly / 中国医学装备

ABSTRACT

Objective:To investigate the exercise echocardiography in the diagnosis Heartbeat application map in elderly coronary heart disease.Methods: One hundred and ninety-six elderly patients with coronary artery disease screening in 2013 January to 2014 June in our hospital were, as the research object. All patients underwent coronary angiography or operation treatment for coronary heart disease confirmed, first Heartbeat figure examined and diagnosed with conventional ultrasound, by exercise echocardiography combined with Doppler tissue imaging Heartbeat graph counting diagnosis and disease evaluation, diagnosis and disease evaluation results of statistical conventional echocardiography and exercise load method, and compare with a gold standard of coronary angiography.Results: conventional ultrasound Heartbeat diagram group detected 143 cases (72.96%), the joint inspection group detected 188 cases (95.92%), two inspection scheme comparison of the results of the existence of significant differences, exercise load method and the gold standard to compare the same no statistical significance; evaluation of coronary heart disease in conventional ultrasound Beckoning evaluation map was lower than the exercise ability load method, without statistical significance.Conclusion: exercise echocardiography beckoning diagram combined with Doppler tissue imaging in elderly patients with coronary artery disease detection rate and coronary angiography results are basically the same, and no iatrogenic injury to the patients, more convenient operation, inspection, examination cost is relatively low, with the clinical application and popularization value.
