Clinical value of cardiac ultrasound in the diagnosis of segmental ventricular wall motion abnormalities of coronary heart disease / 中国基层医药

ABSTRACT

Objective To explore the application value of cardiac ultrasound in the diagnosis of segmental ventricular wall motion abnormality of coronary heart disease (CHD),and to continuously improve the diagnosis and treatment quality of CHD.Methods From January 2015 to April 2017,200 CHD patients with segmental ventricular wall motion abnormalities(the echocardiographic diagnosis) in the Fourth People~ Hospital of Datong were selected in the research.Before treatment,the patients received cardiac ultrasound examination,checked out the segmental ventricular wall motion abnormalities,the coronary artery angiography was used for further identification.The cardiac ultrasound detection rate was calculated.The adverse reactions after coronary angiography were recorded.Results Echocardiography showed normal results in 16 cases(8.00％) and 184 cases(92.00％).And 184 cases(92.00％) were diagnosed with segmental wall motion abnormality by coronary angiography,that is,the disease detection rate of cardiac ultrasonic examination was 92.00％.No adverse reactions were found after receiving cardiac ultrasound examination.After coronary angiography examination,there were allergic reactions,nausea and other discomfort reactions,but the difference was not statistically significant(x2 =26.64,P ＞0.05).Conclusion In the diagnosis of segmental ventricular wall motion abnormality of CHD,coronary angiography has high accuracy but it is expensive,and cardiac ultrasound examination is highly accurate and non-invasive,and can be selected by grassroots hospitals without the conditions of coronary angiography.
