The diagnostic value of ambulatory electrocardiography combined with carotid ultrasound for coronary heart disease in elderly patients / 中华老年医学杂志

ABSTRACT

Objective To evaluate the predictive value of ambulatory electrocardiography (AECG) and carotid ultrasound (CUS) for coronary heart disease (CHD) in elderly patients.Methods A total of 240 elderly patients receiving coronary angiography at our hospital from December 2015 to December 2017 were recruited to this study and were divided into a CHD group (n =147) and a non-CHD group (n=93).Data of ambulatory electrocardiography and carotid ultrasound for each patient were collected and evaluated for their sensitivity,specificity,positive predictive value,and negative predictive value.Results Six patients (6.5％) in the non-CHD group and 111 Patients (75.5％) in the CHD group had AECG-detected ST-segment deviation and thick CIM,and the difference between the two groups was statistically significant (x2 =108.732,P ＜0.01).The sensitivity,specificity,positive and negative predictive values of AECG combined with CUS were 75.5 ％,93.6 ％,94.5 ％,and 70.4％,respectively.Conclusions AECG combined with CUS has a good specificity for the diagnosis of coronary heart disease.
