Abstract: Objective To explore the effect of comprehensive intervention on anxiety in patients of acute myocardial infarction (AMI) undergoing intra-aortic balloon pump (IABP). Methods 50 patients with AMI undergoing IABP with the score of Hamilton Anxiety Rating Scale (HAMA) more than 14 points, were divided into conventional intervention group (n=25) and comprehensive intervention group (n=25). The conventional intervention group received all the conventional nursing measures including cognitive behavioral intervention, and the comprehensive intervention group received propofol intravenous pumping in addition with Ramsay sedation at II-III level. The vital signs, HAMA scores, major cardiovascular events, and vascular complications were recorded before and the 1st-5th days after intervention. Results The HAMA scores, systolic blood pressure, diastolic blood pressure and mean pressure decreased in most of the time points after intervention in the comprehensive intervention group (P<0.05). And there was no complication such as low blood pressure, respiratory depression. The incidence rates of cardiac arrhythmias, puncture hematoma/bleeding and catheter displacement were lower in the comprehensive intervention group than in the conventional intervention group (P<0.05). Conclusion Comprehensive intervention can improve the symptoms of anxiety in the patients with AMI undergoing IABP, and reduce the incidence of arrhythmia, vascular complications and catheter displacement.
