Multivariate analysis evaluated 24 clinical and angiographic variables, comparing those with and without angina. Results Restenosis occurred in 32 patients with clinical silence (55%) and 27 patients with angina. Male sex ( P =0.03 ), absence of antianginal therapy with nitrates ( P =0.002 ) ,greater reference diameter after the procedure ( P =0.04 ), greater reference diameter at follow up (P=0.01), and less lesion severity at 6 months ( P =0.04 ) were univariate predictors of asymptomatic restenosis. By multivariate analysis, only male, greater reference diameter at follow up, and less lesion severity at 6 months were associated with restenosis without angina.Conclusions Approximately half of patients with angiographic restenosis have no symptoms. The only multivariate predictors of silent restenosis at 6 months were male sex, greater reference diameter at follow up, and less lesion severity on follow up angiography.展开更多

Methods: a total of 128 patients with CORONARY heart disease complicated with type 2 diabetes who underwent PCI in our hospital from December 2018 to December 2020 were included. The self-assessment of symptom self-rating scale SCL90 was performed first, and they were divided into control group and observation group according to the score: In the control group, patients with total score < 160 points showed no psychological stress or mild psychological stress;The observation group was the patients with total score ≥160, indicating the existence of serious psychological stress phenomenon. The glucose metabolism indexes of the two groups were analyzed after PCI. Results: the specific indicators of glucose metabolism level in the observation group after PCI were higher than those in the control group, with statistical significance (P < 0.05). Conclusion: the degree of psychological stress is closely related to the relevant indicators of glucose metabolism in patients with coronary heart disease combined with type 2 diabetes after PCI. The more serious the degree of psychological stress is, the more adverse it is to the recovery of the disease, which needs clinical attention and timely psychological intervention.展开更多

Methods: 45 cases of AMI patients who underwent PCI in our hospital from January 2020 to December 2020 were selected as the observation group for early staged rehabilitation nursing, and 45 cases of patients undergoing routine nursing were selected as the contrast group. Cardiac function index level, incidence of adverse events and quality of life were compared between the two groups. Results: the levels of LVEF and LVEDV in the observation group were significantly better than those in the control group (P < 0.05). There was no significant difference in the incidence of coronary artery restenosis and heart failure between the two groups and the control group (P > 0.05). The incidence of arrhythmia and angina pectoris in the observation group was lower than that in the control group (P < 0.05). The SAQ index scores in observation group were significantly higher than those in control group (P < 0.05). Conclusion: the early implementation of staged rehabilitation nursing in patients with acute myocardial infarction after PCI is helpful to improve cardiac function, reduce the incidence of adverse events, and improve the quality of life, which has clinical value of promotion and application.展开更多
