ObjectiveTo observe the clinical effect of transradial approach interventional therapy in the treatment of elderly patients with coronary heart disease complicated with chronic left heart failure. MethodsA total of 78 cases of elderly patients with coronary heart disease complicated with chronic left heart failure were randomly divided into control group and observation group, 39 cases in each group. Patients in control group were treated with femoral artery interventional therapy, and patients in observation group were treated with transradial interventional therapy. The operation time, time from puncture to intubation and time of X-ray exposure of the two groups were compared; Complications related to puncture, lower extremity deep venous thrombosis and acute left heart failure were observed. ResultsTime from puncture to intubation, X-ray exposure time, postoperative time in bed and length of hospital stay of observation group were shorter than those of control group,the difference was statistically significant(P＜0.05); There was no significant difference in operation time between the two groups (P＞0.05). Compared with control group, the incidence rates of puncture related complications, lower extremity deep venous thrombosis and acute left heart failure in the observation group were lower (P＜0.05). ConclusionsTransradial approach interventional therapy in the treatment of elderly patients with coronary heart disease complicated with chronic left heart failure has few trauma and postoperative complications. It is conducive to promote patients to get out of bed as soon as possible and speed up the process ofrecovery.
