Study on the correlation between dietary structure and restenosis of patients after pereutaneous coronary intervention

Abstract

Objective To explore relationship between dietary structure and restenosis of patients after PCI. Methods Select a total of 240 cases of PCI postoperative imaging review of coronary heart disease patients as the research object. General information questionnaire and food frequency questionnaire were used. Analyze the relationship between dietary structure and restenosis of patients after pereutaneous coronary intervention. Results The intakes of fruits, vegetables and dairy products were 40.83%(98/240), 35.42%(85/240) and 44.58%(107/240), respectively, and the proportion of meat, grease and salt was higher in poultry, 46.25%(111/240), 73.33%(176/240) and 57.08%(137/240), and the intake of vitamin B6, folic acid, vitamin C and calcium were higher, 75.83%(182/240), 59.17%(142/240), 47.50%(114/240) and 54.58%(131/240) respectively; the body mass index, body fat rate and smoking history were positively correlated with restenosis after PCI (r=0.276, 0.183, 0.334, P<0.05), and the intake of thiamine, riboflavin, vitamin C, vitamin E, magnesium, zinc and selenium was negatively correlated with restenosis (r=-0.257--0.163, P<0.05) The body mass index, vitamin C and selenium intake were the main influencing factors of restenosis (Wald χ2=4.398, 3.928, 5.217, P<0.05). Conclusions The patients' diet structure is poor and the nutrition is unbalanced, and the clinical nursing staff should strengthen the dietary guidance to patients, which is beneficial to prevent the occurrence of restenosis.
