Effect of monitoring the plasma brain natriuretic peptide levels combined with continuous nursing intervention on the prognosis of patients with acute myocardial infarction who undergone emergency percutaneous coronary intervention

Abstract

Objective To investigate the plasma brain natriuretic peptide （BNP） levels in the acute myocardial infarction （AMI） patients who undergone emergency percutaneous coronary intervention （PCI）, and to explore the method and effect of nursing. Methods One hundred and thirty AMI patients with emergency PCI were divided into the intervention group and the control group according to the order of admission, each with 65 cases. The control group received the routine treatment and nursing, and the intervention group received the specific nursing intervention according to the level of BNP on the basis of the control. The major adverse cardiovascular events （MACE） were investigated within the six months of follow-up, and the quality of life was evaluated by the Seattle angina questionnaire （SAQ） in the two groups. Results The cases of MACE including heart failure, myocardial infarction, arrhythmia, angina pectoris, sudden cardiac death were four cases （6. 2% ） in the intervention group, and were significantly lower than fifteen cases （23.1% ） in the control group, and the difference was statistically significant （ X^2 = 7.45 ; P 〈 0. 01 ）. The scores of SAQ including the activity limitation, the attack of angina pectoris, the stability of angina pectoris, treatment satisfaction, subjective feeling and total were respectively （79. 69 ± 11.87）, （95.13 ± 13.02）, （91.32 ± 11.05）, （79. 86 ± 8. 39）, （74. 12 ± 14. 18）, （82. 50 ± 15. 12） in the intervention group, and were higher than （60. 28 ± 9. 73 ）, （ 84. 60 ± 10. 89）, （78. 24 ±9. 59）, （68.21 ±7.45）, （60. 56 ± 11.64）, （69.45 ± 13.26） in the control group, and the differences were statistically significant （ t = 8.02,5.23,5.95,7. 14,7. 88,6. 45, respectively; P 〈 O. O1 ）.Conclusions According to the level of BNP in the patients with emergency PCI, the specific nursing intervention can reduce the incidence rate of MACE and improve the life quality of the patients.
