Objective To investigate the scientificity of patient-reported outcomes instrument for asthma ( Asthma-PRO) , which maybe used to evaluate the efficacy of anti-asthma drugs in clinical trials and clinical practice.Methods 366 asthma patients and 100 healthy subjects were face-to-face interviewed by well-trained investigators, and the data of Asthma-PRO instrument were collected. The psychometric performance such as reliability, validity, responsiveness and clinical feasibility in the Asthma-PRO instrument was evaluated. Results The split-half reliabilities of the Asthma-PRO instrument and each dimension were greater than 0.8. In the analysis of internal consistency of each dimension, the cronbach’s alpha coefficient was greater than 0.7. Factor analysis showed that the instrument has good construct validity. The scores of each of the facets and total scores between the asthma patients and the healthy subjects were different. The recovery rate and the efficient rate of the questionnaire were more than 95%, and the time required to complete a questionnaire was within 20 minutes, indicating that the scale had a high clinical feasibility. Conclusion The Asthma-PRO instrument has good reliability, validity, responsiveness and clinical feasibility.
Deep hypothermic circulatory arrest (DHCA) is an important assistant technique for complex cardiac surgery, which creates convenient operating conditions for surgery, and is also one of the measures to protect the brain during operation. However, the complications caused by this technique cannot be ignored, and it should be noticed that the occurrence of intestinal injury is relatively insidious, but brings great pain to patients and significantly reduces the quality of life after operation. Studies have shown that intestinal ischemia-reperfusion injury is induced by DHCA. It causes mast cells to activate and release many inflammatory mediators that destroy the intestinal mucosal epithelium barrier, and eventually lead to intestinal injury. This article reviewed the research progress of mast cells in the mechanism of DHCA-induced intestinal injury.
As technology advances, current evidence supports the use of devices for valvular heart disease interventions, including transcatheter aortic valve implantation, transcatheter mitral or tricuspid valve repair, and transcatheter mitral valve implantation. These procedures require antithrombotic therapy to prevent thromboembolic events during the perioperative period, and these therapies are associated with an increased risk of bleeding complications. To date, there are challenges and controversies regarding how to balance the risk of thrombosis and bleeding in these patients, and therefore the optimal antithrombotic regimen remains unclear. In this review, we summarize the current evidence for antithrombotic therapy after transcatheter intervention in patients with valvular heart disease and highlight the importance of an individualized approach in targeting these patients.
ObjectiveTo summarize the perioperative management strategies and early results of modified Morrow expanded operation and coronary artery bypass grafting (CABG) in patients with hypertrophic obstructive cardiomyopathy (HOCM) and coronary atherosclerotic heart disease.MethodsBetween January 2012 and December 2017, in the Second Inpatient Department of Fuwai Hospital, 32 patients (20 females and 12 males) underwent modified expanded Morrow operation and CABG. The median age was 53.7±8.7 years (interquartile range 37 to 67 years). Preoperative chest distress symptom was found in 24 patients, chest pain symptom was found in 14 patients, history of syncope in 6 patients. Cardiac echocardiography, electrocardiogram, chest X-ray, magnectic resonance imaging (MRI) were performed routinely after operation and follow-up to analyze structure and function of heart and mitral valve.ResultsAll patients underwent modified and expanded Morrow combined with CABG. The preoperative left ventricular outflow tract peak pressure difference (LVOTG) was 40 to 152 (79.6±28.7) mm Hg. Four patients underwent myocardial bridge releasing in the same period, mitral valve replacement in 2 patients, mitral valve angioplasty in 3 patients, Maze operation in 2 patients and tricuspid valveoplasty in 3 patients. There was no hospital mortality. CABG surgery in patients with branches included anterior descending artery in 26 patients, diagonal branch in 16 patients, left circumflex in 8 patients, right coronary artery in 11 patients. There were 15 patients with one coronary artery (CA) bypass graft, 5 patients with two CA bypass grafts, and 12 patients with 3 CA bypass grafts. The average of CA bypass grafts was 1.9±0.6. The postoperative ICU time ranged from 1–13 (4.1±2.8) days and postoperative hospital stay ranged from 7 to 30 (12.6±5.5) days. No severe postoperative complications were found and 1 patient had postoperative incision healing. The postoperative new arrhythmia included left bundle branch block in 6 patients. Compared with the preoperative values, postoperative left ventricular outflow tract peak pressure (79.6±28.7 mm Hg vs. 10.8±5.9 mm Hg, P<0.001), interventricular septum thickness (1.9±0.4 cm vs. 1.3±0.5 cm, P<0.001) were decreased obviously. Mitral valve closure is good or only mild reflux, mitral valve forward movement (SAM sign) disappeared. The patients were followed up for 6-68 months, with an average of 38.8±20.6 months. All patients were followed up with symptoms disappeared or only mild symptoms. NYHA classification decreased Ⅰ to Ⅱ grade after surgery, without long-term mortality, complications or reoperation.ConclusionFor patients with hypertrophic obstructive cardiomyopathy with coronary atherosclerotic heart disease, the application of improved expand morrow operation at the same time undergoing coronary artery bypass grafting is safe. It can significantly improve patients' survival and reduce symptoms, play a synergistic effect, and do not increase the patient's surgical complications.
In recent years, transesophageal echocardiography has a trend toward miniaturization, so it has great clinical significance and broad clinical application prospect in the management of Cardiac Surgery ICU patient. This paper presents the characteristics of miniaturized transesophageal echocardiography and its clinical application. And we also focused on the contrast between miniaturized transesophageal echocardiography and standard transesophageal echocardiography and transthoracic echocardiography.
ObjectiveTo evaluate the anticoagulation efficacy of non-vitamin K antagonist oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) in patients with high-risk atrial fibrillation (AF) undergoing transcatheter aortic valve implantation (TAVI). MethodsA computer-based search was conducted on PubMed, EMbase, The Cochrane Library, CNKI, SinoMed, and VIP databases to identify studies on the application of NOACs and VKAs in high-risk AF patients after TAVI. The search period was from database inception to January 2023. The quality of the included studies was assessed using the Cochrane risk assessment tool and the Newcastle-Ottawa Scale (NOS). Meta-analysis was performed using RevMan 5.4 software. ResultsA total of 7 studies involving 24 592 patients were included. The meta-analysis results showed that compared to patients using VKAs, those treated with NOACs had a significantly lower risk of all-cause mortality [RR=0.74, 95%CI (0.58, 0.94), P=0.01]. Subgroup analysis indicated that when the follow-up period was less than 1 year, there was no significant difference in all-cause mortality between the NOAC and VKA groups [RR=0.57, 95%CI (0.17, 1.88), P=0.35]; however, when the follow-up period was ≥1 year, the VKA group had a higher all-cause mortality rate than the NOAC group, with a statistically significant difference [RR=0.73, 95%CI (0.57, 0.95), P=0.02]. No significant differences were found between the two groups regarding early stroke [RR=0.50, 95%CI (0.19, 1.28), P=0.15], stroke during follow-up [RR=1.04, 95%CI (0.88, 1.22), P=0.64], bleeding [RR=0.94, 95%CI (0.73, 1.21), P=0.61], major or life-threatening bleeding [RR=0.80, 95%CI (0.49, 1.31), P=0.38], or acute kidney injury [RR=0.51, 95%CI (0.16, 1.59), P=0.24]. Conclusion Compared to VKAs, the use of NOACs in patients with high-risk AF undergoing TAVI may reduce the risk of all-cause mortality, especially during long-term anticoagulation therapy, potentially offering greater benefits. However, further evidence from randomized controlled trials is needed to confirm these findings.
Objective To explore the effectiveness of arthroscopic-assisted closed reduction and internal fixation with absorbable screws in the treatment of Hawkins type Ⅱ talar neck fractures. Methods A retrospective analysis was conducted on the clinical data of 31 patients with closed Hawkins type Ⅱ talar neck fractures between October 2021 and July 2023, all of whom were treated with arthroscopic-assisted closed reduction and internal fixation with absorbable screws. There were 18 males and 13 females with an average age of 35.9 years (range, 17-61 years). Causes of injury included sports injuries in 26 cases and impact injuries in 5 cases. The time from fracture to operation was 3-5 days (mean, 3.7 days). During follow-up, ankle pain and function were assessed using the visual analogue scale (VAS) score and the American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score (AOFAS-AHS), while radiological examinations were used to evaluate the quality of fracture reduction and healing. ResultsAll operations were successfully completed, and all incisions healed by first intention. All patients were followed up 12-16 months (mean, 13.0 months). One patient experienced persistent pain, limping, and joint dysfunction postoperatively, which returned to normal after symptomatic treatment. At 3 months after operation and last follow-up, the VAS scores were 2.7±0.9 and 1.3±0.8, respectively; the AOFAS-AHS were 74.5±4.7 and 90.9±3.6, respectively. There were significant differences in VAS score and AOFAS-AHS between different time points (P<0.05). At last follow-up, all fractures healed, and the internal fixation was secure. No complication such as talar necrosis, subtalar joint stiffness, wound infection, or screw irritation occurred during follow-up. Conclusion Arthroscopic-assisted closed reduction and internal fixation with absorbable screws for Hawkins type Ⅱ talar neck fractures has the advantages of minimal trauma, precise screw placement, few complications, and avoiding secondary screw removal, with satisfactory effectiveness.
ObjectiveTo explore the risk factors and potential mechanisms of hypertension events on the same day after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis. MethodsClinical data of patients who underwent TAVI for severe aortic stenosis at Department of Structural Heart Disease, Fuwai Hospital from December 2023 to February 2024 were retrospectively collected. According to the peak systolic blood pressure on the same day after surgery, patients were divided into a hypertension group (≥140 mm Hg) and a normal blood pressure group (<140 mm Hg). Logistic regression model was used to analyze the risk factors for hypertension on the same day after TAVI. ResultsA total of 54 patients after TAVI were included, with 41 patients in the hypertension group, including 18 males and 23 females, with an average age of (72.83±6.78) years; 13 patients in the normal blood pressure group, including 9 males and 4 females, with an average age of (70.00±7.57) years. Univariate analysis found that there were statistical differences in interventricular septal thickness [(13.71±1.98) mm vs. (12.23±1.59) mm, P=0.018], preoperative left ventricular ejection fraction (LVEF)>55% [33 (80.5%) vs. 6 (46.2%), P=0.040], and postoperative same-day LVEF>55% [33 (80.5%) vs. 4 (30.8%), P=0.003]. Multivariate logistic regression analysis found that postoperative same-day LVEF>55% [OR=10.173, 95%CI (1.044, 99.115), P=0.046] was an independent risk factor for hypertension on the same day after TAVI. ConclusionMyocardial contractility mainly participates in the occurrence of hypertension on the same day after TAVI. This study can not only improve our understanding of early hemodynamic changes after TAVI, but also provide a basis for the formulation of early hypertension treatment plans after TAVI to improve the short- and long-term prognosis of patients.
The "2022 AHA/ACC/HFSA guideline for the management of heart failure" replaces the "2013 ACCF/AHA guideline for the management of heart failure" and the "2017 ACC/AHA/HFSA focused update of the 2013 ACCF/AHA guideline for the management of heart failure". The 2022 guideline is intended to provide patient-centric recommendations for clinicians to prevent, diagnose and manage patients with heart failure. Heart failure remains a leading cause of morbidity and mortality globally. The 2022 heart failure guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to manage patients with heart failure, with the intent to improve quality of care and align with patients’ interests. New recommendations have been created when supported by published data. Value statements are provided for certain treatments with high-quality published economic analyses. This article summarized and interpreted the new concept of heart failure in 2022 guidelines, especially the new evidence and suggestions related to cardiac surgery.
Objectives To retrospectively analyze the isolation rate and drug-resistance of pseudomonas aeruginosa in Fuwai Hospital of Chinese Academy of Medical Sciences from 2013 to 2016. Methods The specimens were collected and cultured. If the isolated bacteria were from the same part of the same patient, the first isolated strains were only counted. The isolated pathogens were identified and the drug-resistance were analyzed. Results A total of 1 404 pseudomonas aeruginosa were isolated. The majority of them were from postoperative recovery room of surgery department (62.1%) and ICU of internal medicine (22.3%). The specimen source were mainly from respiratory tract (75.7%), followed by blood (10.0%) and venous catheter (5.5%). The resistance rate of piperacillin and piperacillin/sulbactam to pseudomonas aeruginosa was 0.6% to 10.4%. The resistance rate of ceftazidime and cefepime was 0.3% to 11.7%. The resistance rate of imipenem and meropenem was 7.6% to 20.1%. The resistance rate of amikacin, gentamicin, and tobramycin was 0.3% to 3.2%. The resistance rate of ciprofloxacin and levofloxacin was 0.6% to 5.2%. Conclusions The isolates of pseudomonas aeruginosa are mainly from postoperative recovery room of surgery department and ICU of internal medicine . Imipenem and meropenem are not the best choices for pseudomonas aeruginosa infection. It has great value to combine piperacillin, piperacillin/sulbactam, ceftazidime and cefepime with aminoglycoside or quinolone antibiotics for the treatment of pseudomonas aeruginosa infection which will reduce drug resistance.
