RESUMO
Objective:To investigate the effect of mind mapping on the discharge readiness of patients undergoing first coronary stent implantation, so as to provide basis for seeking effective discharge guidance in clinical practice.Methods:One hundred patients who were hospitalized in the Department of Cardiology, the Second Affiliated Hospital of Dalian Medical University from December 2019 to August 2020 and who underwent coronary stent implantation for the first time were selected as the study objects. They were divided into the control group and the experimental group with 50 cases in each group by the random number table method. The control group was given routine discharge guidance, and the experimental group was given discharge guidance using mind mapping. Readiness for Hospital Discharge Scale and Quality of Discharge Teaching Scale were used to compare the differences of discharge readiness and discharge guidance quality between the two groups after intervention.Results:The personal status, adaptability, predictive support and the total score of discharge readiness in the experimental group were (25.18 ± 3.79), (45.24 ± 3.63), (36.62 ± 3.63), (107.04 ± 8.92) points, which were all higher than those in the control group (23.34 ± 3.04), (41.68 ± 3.62), (35.14 ± 2.14), (100.16 ± 7.36) points, with statistically significant differences ( t values were -4.91--2.48, all P<0.05). The actual acquired content, guiding skills and results, total scores of discharge guidance quality of patients in the experimental group were (56.66 ± 6.06), (94.46 ± 4.33), (151.12 ± 8.26) points, which were all higher than those in the control group (45.38 ± 9.19), (89.44 ± 10.87), (134.82 ± 14.31) points, with statistically significant differences ( t values were -7.25, -3.03, -6.97, all P<0.05). Conclusions:Mind mapping can effectively improve the discharge preparation degree and discharge guidance quality of patients undergoing coronary stent implantation for the first time, and it is a simple and practical discharge guidance tool.
RESUMO
BACKGROUND: Percutaneous coronary intervention (PCI) has become increasingly mature and has gradually become the main treatment for coronary heart disease (CHD). However, evaluation of myocardial reperfusion after PCI remains a major clinical challenge. This study aimed to explore the VVI technique in evaluating the effect, prognosis, and follow-up of CHD patients after percutaneous coronary intervention. We performed a quantitative analysis of left ventricular myocardial contractile strain and dyssynchrony before and after stent implantation in patients by VVI. METHODS: Thirty-five patients diagnosed with CHD who underwent percutaneous coronary stenting (PCI) in the Department of Cardiovascular Medicine, Affiliated Hospital of Jiangnan University from March 2019 to October 2020 were selected as the case group. Continuous dynamic two-dimensional images of the patient's left ventricle were analyzed using VVI at 1 day before PCI (group A), 7 days after PCI (group B), and 30 days after PCI (group C). The patients' left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricle ejection fraction (LVEF), peak longitudinal strain, and peak radial strain of myocardial contraction were measured. The VVI images of 35 healthy subjects who underwent physical examination in the outpatient department of our hospital from March 2019 to October 2020 were selected as controls. RESULTS: There were no significant differences in the LVEF, LVEDD, and LVESD between the case and control groups (P>0.05). The peak systolic longitudinal and radial strain values at 1 month after treatment were higher than those before treatment. The differences among myocardial segments were statistically significant, except for the apical septum, base anterior, apical anterior, and base inferior segments (P<0.05). The peak systolic longitudinal and radial strain values at 1 week after treatment were not significantly different from those at 1 month after treatment, except for the base anterior septum, mid anterior, posterior, and inferior myocardial segments (P>0.05). CONCLUSIONS: VVI technology can comprehensively and objectively evaluate the overall and local myocardial function of the left ventricle, thereby providing a novel method for the clinical treatment of CHD as well as the evaluation of curative effect and prognosis.

The everolimus-eluting biovascular scaffold (BVS) does not contain any metal, therefore struts are not evident angiographically. Two adjacent platinum radio-opaque markers at each end facilitate precise location of stent ends. Here we report one case of anomalous left main stenting using BVS. The BVS got accidentally distorted in left main during the procedure, which was not visible on angiography but detected on OCT.
