Objective To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.
The main purpose of this study is to observe and analyze the characteristics and the clinical significance of long-term echocardiogram data in patients after mechanical aortic valve replacement operation. Fifty-five cases were recruited over 5 years after mechanical aortic valve replacement operation, with complete echocardiogram examination profiles. The 55 subjects were divided into predominate aortic stenosis group and predominate aortic regurgitation group, based on preoperative examinations. And another way of division was also carried out that according to the effective orifice area index (EOAI), the subjects were divided into three groups, i.e., severe prosthesis-patient mismatch (PPM) group, moderate PPM group, and non PPM group. Characteristics of long-term echocardiogram data of the subjects were analyzed. Patients with aortic stenosis showed significantly decreased thickness of intraventricular septum and left ventricular posterior wall about half a year after operation (P<0.05). Half a year after operation, patients with aortic regurgitation showed decreased left ventricular internal dimension diastole and left ventricular internal dimension systole, and increased ejection fraction (P<0.05). Differences in mean aortic valve pressure gradient, forward blood flow across the aortic valves, and ejection fraction were not significant among those with severe PPM, moderate PPM, and non PPM groups (P>0.05). Number of cases of ascending aorta dimension increased as time goes on and pathogenesis of other valve diseases. A conclusion could be drawn that the heart function of patients with aortic valve disease could be improved after mechanical aortic valve replacement operation, but pathologies in other valves and ascending aorta might be increased, and therefore periodical postoperative echocardiogram evaluation with long tem pharmaceutical therapy could be necessary.
Objective To evaluate and summarize the relevant evidence on follow-up management of non-pregnant adult with pulmonary embolism, and provide a reference for optimizing the follow-up plan of non-pregnant adult with pulmonary embolism. Methods Clinical decision-making, guidelines, societies/associations websites related to follow-up of pulmonary embolism, and databases were searched for literature on follow-up management of non-pregnant adult with pulmonary embolism. The retrieval time limit was from databases establishment to December 2023. The included literature was evaluated for quality and summarized to form evidence. Results A total of 13 articles were included, including 3 clinical decision-making articles, 5 guidelines, 1 systematic review, and 4 expert consensus articles, forming 26 best pieces of evidence, involving 8 aspects of follow-up personnel and methods, follow-up time, physical assessment, activity guidance, contraception guidance, filter management, medication guidance, and lifestyle guidance. Conclusions The follow-up management of non-pregnant adult with pulmonary embolism is very important. When medical staff apply relevant follow-up management evidence, they should fully evaluate the patients’ willingness and medical environment, make full use of existing resources, optimize follow-up management strategies, reduce the occurrence of complications, and improve patient prognosis.
Objective To explore the factors associated with clinic follow-up of old patients with colorectal cancer and provide more evidence to improve the efficiency and quality of clinic follow-up after sugery. Methods The data of 253 patients who were underwent sugery because of old colorectal cancer in our hospital from January 2009 to May 2010 were reviewed. Data about the rate and times of clinic follow-up within 6 months after operation were collected via Hospital Information Systerm, then the follow-up rate was calculated, and to analyse the possible factors associated with follow-up times and rate. Results The total follow-up rate was 84.2%（213/253）, and the total times of follow-up was between 0 to 24 times per one, （4.08±0.03）times on average. On the times of follow-up, patients inside the city was higher than that outside, patients with medical or postoperative complications were higher than those without, and patients with a stoma was lower than that without, and the differences were statistically significant （P＜0.05）.While on the follow-up rate, patients underwent a radical sugery or with a stoma were lower than those not or without, and the differences were statistically significant （P＜0.05）. Conclusions The clinic follow-up of old colorectal cancer patients is not satisfactory, and the possible factors associated with follow-up times or rate are the distance between residence and hospital, have medical complications or not, have postoperative complications or not, radical sugery or not, and with a stoma or without.
Objective To review the research progress of intelligent remote follow-up modes in the application after hip and knee arthroplasty. Methods Extensive literature on this topic published in recent years both domestically and internationally was reviewed, and the application of intelligent remote follow-up modes after hip and knee arthroplasty was summarized and analyzed. Results The intelligent remote follow-up mode is a novel follow-up method based on network information technology. Patients who undergo hip and knee arthroplasty require long-term follow-up and rehabilitation guidance after operation. Traditional outpatient follow-up is relatively time-consuming and inconvenient for some patients in terms of travel and transportation, which makes the application of intelligent remote follow-up modes increasingly widespread worldwide. The inherent attributes of remote interaction and instant feedback of this mode make it particularly valued in the field of hip and knee arthroplasty. Artificial intelligence (AI)-based voice follow-up systems and virtual clinics have significant advantages in improving follow-up efficiency, reducing human resource costs, and enhancing patient satisfaction. Conclusion The existing intelligent follow-up system has formed a standardized protocol in remote follow-up and rehabilitation guidance. However, there are still shortcomings in the formulation of personalized rehabilitation plans and the gerontechnological adaptation of human-computer interaction. In the future, it is necessary to construct a multimodal data fusion platform and establish technical application guidelines for different rehabilitation stages.
ObjectiveTo analyze the results of surgical treatment of severe aortic stenosis in infants.MethodsFrom August 2012 to December 2019, 28 infants undergoing aortic valvuloplasty in our hospital were selected, including 22 males and 6 females, aged 62.00 (47.00, 82.50) d. The baseline characteristics of the patients, postoperative complications and follow-up results were analyzed.ResultsTwenty (71.43%) patients had bicuspid aortic valves. Five (17.86%) patients had heart failure and two (7.14%) patients used prostaglandin before surgeries. Postoperative mechanical ventilation time was 25.00 (17.00, 62.75) h, ICU stay was 3.50 (2.00, 8.50) d and postoperative hospital stay was 10.00 (7.00, 16.50) d. Four (14.29%) patients got delayed recovery (ICU stay>14 d). One (3.57%) perioperative death was observed. The follow-up time was 55.00 (43.25, 82.25) months. No death was found during follow-up. Four (14.81%) patients underwent a second operation, including three (11.11%) patients with severe aortic stenosis, and one (3.70%) patient with severe regurgitation.ConclusionInfants with severe aortic stenosis are seriously ill and have a long postoperative recovery time, requiring early surgery. The postoperative follow-up results are satisfactory.
To summarize the medium-term cl inical result of bio-derived bone transplantation in orthopedics with tissue engineering technique. Methods From December 2000 to June 2001, 10 cases of various types of bone defect were treated with tissue engineered bone, which was constructed in vitro by allogenous osteoblasts from periosteum (1 × 106/ mL) with bio-derived bone scaffold following 3 to 7 days co-culture. Six men and 4 women were involved in this study, aged from 14 to 70 years with a median of 42 years. Among them, there were 2 cases of bone cyst, 1 case of non-union of old fracture, 6 cases of fresh comminuted fracture with bone defect, and 1 case of chronic suppurative ostemyel itis. The total weight of tissue engineered bone was 3-15 g in all the cases, averaged 7.3 g in each case. Results The wound in all the case healed by first intention. For 7 year follow up, bone union was completed within 3.0 to 4.5 months in 9 cases, but loosening occurred and the graft was taken out 1 year after operation in 1 case. The X-ray films showed that 9 cases achieved union except one who received resection of the head of humerus. No obvious abnormities were observed, and the function of affected l imbs met daily l ife and work. Conclusion Bio-derived tissue engineered bone has good osteogenesis. No obvious rejection and other compl ications are observed in the cl inical appl ication.

ObjectiveTo investigate long-term echocardiographic outcomes of patients after mitral and aortic valve replacement and their clinical significance. MethodsA total of 204 patients who underwent mitral and aortic valve replacement from January 1999 to June 2008 in West China Hospital of Sichuan University, and had been followed up with echocardiography for longer than 5 years were enrolled in this study. There were 60 male and 144 female patients with their age ranging from 15 to 74 (48.42±11.00)years. Postoperative follow-up time was 5 to 13 (6.34±2.05)years. Preoperative and follow-up echocardiographic results were compared. ResultsCompared with preoperative results, postoperative left atrial diameter (LA)and left ventricular diameter (LV)significantly decreased (P < 0.05), while right ventricular diameter (RV), left ventricular ejection fraction (LVEF)and left ventricular fractional shortening (LVFS)significantly increased (P < 0.05). Right atrial diameter (RA)did not change significantly (P > 0.05). In the patients mainly with mitral stenosis preoperatively, postoperative LA, LV, left atrial area (LAA), left atrial volume (LAV), mitral mean pressure gradient (MPGmv), velocity time integral (VTImv)and pressure half time (PHTmv)significantly decreased (P < 0.05), while mitral effective orifice area (EOAmv)and effective orifice area index (EOAImv)increased significantly (P < 0.05), but peak E velocity (Emv)did not change significantly (P > 0.05). In the patients mainly with mitral regurgitation preoperatively, postoperative LA and LV decreased significantly (P < 0.05), while LAA, LAV, MPGmv, VTImv, PHTmv, EOAmv and EOAImv did not change significantly (P > 0.05). In the patients mainly with aortic stenosis preoperatively, postoperative LV, interventricular septal thickness (IVS), left ventricular mass (LVM), left ventricular mass index (LVMI), aortic peak forward flow velocity(Vav)and mean pressure gradient (MPGav)significantly decreased (P < 0.05), while aortic effective orifice area (EOAav)and effective orifice area index (EOAIav)significantly increased (P < 0.05), but left ventricular posterior wall thickness (LVPW)did not change significantly (P > 0.05). In the patients mainly with aortic regurgitation preoperatively, postoperative LV, LVM, LVMI, EOAav and EOAIav decreased significantly (P < 0.05), while Vav and MPGav increased significantly (P < 0.05), but IVS and LVPW did not change significantly (P > 0.05). In mitral position, compared with patients with 25 mm prosthesis, Emv, MPGmv and VTImv of patients with 27 mm prosthesis were significantly smaller (P < 0.05), but there was no statistical difference in PHTmv, EOAmv or EOAImv between the 2 groups (P > 0.05). In aortic position, compared with patients with 21mm prosthesis, Vav, MPGav and VTIav of patients with 23 mm prosthesis were significantly smaller (P < 0.05), while EOAav and EOAIav were significantly larger (P < 0.05). In mitral position, 38 patients (21.3%)had moderate prothesis-patient mismatch (PPM)and 4 patients (2.3%)had severe PPM. In aortic position, 50 patients (24.5%)had moderate PPM and 43 patients (21.1%)had severe PPM. Consti-tuent ratio of long-term tricuspid regurgitation (TR)degree of patients after tricuspid valvuloplasty (TVP)significantly improved (P < 0.05), but constituent ratio of long-term TR degree of patients without TVP significantly deteriorated (P < 0.05). ConclusionsLeft ventricular function and hemodynamic outcomes in the long term are significantly better than preoperative results after double valve replacement, but they are still far from normal. PPM in aortic position is more severe than that in mitral position. Since residual or aggravated TR is very common in the long term, concomitant TVP should be considered more positively for patients undergoing surgery for left-sided valvular disease.
ObjectiveTo explore the influencing factors for lost follow-up of diabetic patients, looking for suitable follow-up methods for patients in the region of Central and Western China, in order to help ensure the quality of follow-up, improve the rate of follow-up and provide a basis for improving the quality of patients' continuous nursing outside of the hospital. MethodsContinuous nursing was carried out for 600 patients discharged from our department by two full-time diabetes education nurses from September 2012 to April 2014. The data of outside hospital patients who were lost in the follow-up were retrospectively analyzed. According to the sequential order of the patients, they were divided into three groups. The difference among the three groups of patients was analyzed and the effect of nursing intervention on patients' follow-up loss was also analyzed. ResultsThe rate of lost follow-up for the three groups were 29.4%, 20.3%, and 12.2%. Big classroom participation rate was 29.4%, 50.5%, and 57.5%. The lost follow-up rate of group three using team comprehensive management pattern was lower than that in group 1 with traditional supervision intervention. The age of the patients who were lost in the follow-up concentrated under 40 and above 75 years old. The patients with a disease history longer than 10 years with more complications were more likely to be lost in the follow-up. The main reason for lost follow-up was self-conceit and lack of awareness of the follow-up. ConclusionDiversified ways of follow-up can complement each other which can reduce the rate of lost follow-up.
