Abstract:
Objective To investigate the evaluation index of cardiac insufficiency induced by chronic obstructive pulmonary diseases ( COPD) .Methods One hundred and twenty-seven patients with COPD , who sought medical care from January to June , 2015 at our hospital , were used as research subjects .Clinical medical data and main detection results during hospitalization were collected for the study.Main risk factors of cardiac insufficiency induced by COPD were analyzed by using non -conditional single factor and multi -factor Logistic method , and the probability of cardiac insufficiency occurred in each patient was estimated by nomogram .Results There was statistical significance in the variations of pH and PCO 2 values of the first main component (blood), BNP, diagnostic classification and ECG(P<0.05).Multivariate Logistic regression analysis indicated the following results:blood(OR=1.35, 95%CI:0.74-2.49), BNP (OR=1.06, 95%CI:1.00-1.10), conduction block ratio(OR=12.58, 95%CI:2.19-72.17)and COPD stage 4 versus stage 3 (OR=1.29 , 95% CI:0.39-4.20), which were all risk factors inducing cardiac insufficiency .Area under curve(AUC)value was 0畅794(95%CI:0.69-0.90).Conclusion The values of pH, PCO2 and BNP were elevated.ECG diagram indicated that conduction block and high grade of COPD were all risk factors of poor prognosis of cardiac insufficiency induced by COPD .For this reason, appropri-ate treatment should be implemented on the basis of above detections , so as to reduce incidence of cardiac insufficiency induced by COPD .
