Abstract
Objective To investigate the evaluation effect of echocardiography for cardiac status in patients with chronic obstructive pulmonary disease (COPD). Methods A total of 168 patients with COPD from February 2014 to February 2016 were selected as the study group, the other 45 cases of health examination in the same period were selected as the control group.The left heart system, the right heart system and the value of left heart myocardial longitudinal strain and right heart myocardial longitudinal strain were compared. The COPD patients were divided into mild group, moderate group and severe group, the left heart, right heart, the value of left heart myocardial longitudinal stain and right heart myocardial longitudinal strain of the three groups were compared. Results In the study group, the left atrial diameter, pulmonary artery systolic pressure were higher than those in the control group; the left ventricular fractional shortening of left ventricular ejection fraction, right ventricular ejection fraction, right ventricular surface change were lower than those in the control group; the volume change scores were significantly lower than those in the control group; the left ventricular longitudinal strain, right ventricular longitudinal strain were significantly lower than those in the control group, and the differences were significant(P<0.05). In the mild, moderate and severe COPD group, the left atrial diameter, pulmonary artery systolic pressure, left ventricular short shortening, left ventricular ejection fraction, right ventricular fractional area change with the severity of the disease was gradually changed(P<0.05). The left ventricular longitudinal strain, right ventricular longitudinal strain with the severity of the disease was gradually changed, the differences were significant(P<0.05). Conclusions The state of heart function of patients with chronic obstructive pulmonary disease detected by echocardiography shows, with the severity of chronic obstructive pulmonary disease, the function of the patient’s left and right ventricle is gradually declining, and there is good performance in mild and moderate COPD patients. It is a way to identify patients with early chronic obstructive pulmonary disease, and it is worthy of clinical application.
