ABSTRACT

Objective:To investigate the differences in outcomes of surgical strategies and prognosis of patients with acute type A aortic dissection(ATAAD) during the period of COVID-19 Omicron variant epidemic compared with the non-epidemic period.Methods:Clinical data were retrospectively collected from ATAAD patients during the COVID-19 Omicron variant epidemic(December 7, 2022 to January 10, 2023) and during the non-epidemic period(December 7, 2019 to January 10, 2020) to compare the differences in surgical strategies, perioperative mortality, and perioperative complication rates in ATAAD patients during the two different periods.Results:There were 14 patients in the COVID-19 infected group and 43 patients in the control group. Patients in the infected group had a shorter mean aortic clamp time[(89.71±16.27)min vs.(110.09±28.99)min, P<0.01], a significantly higher postoperative mortality rate relative to the control group(21.43% vs. 2.33%, P=0.02), a significantly longer length of stay in the ICU(3 days vs. 2 days, P=0.04) and the duration of intubation time(34 h vs. 14 h, P<0.01), and the incidence of adverse events, mainly cerebral infarction, was higher in infected group(28.57% vs. 6.98%, P=0.03). Conclusion:During the COVID-19 Omicron variant strain epidemic, our center preferred a more conservative surgical strategy in COVID-19 infected patients. Although the COVID-19 infection increased the postoperative mortality and complication rate of ATAAD, patients still achieve a more satisfactory outcome. Therefore, surgical treatment should be timely performed for ATAAD patients.

ABSTRACT

The end of the COVID-19 infection peak in 2022 prompts a backlog of cardiovascular surgical patients to gradually return to the hospital, resulting in a surge in cardiovascular surgeries. However, against the backdrop of the COVID-19 pandemic, the clinical practice of cardiovascular surgery faces many problems. Therefore, organized by Beijing Anzhen Hospital, experts in cardiovascular surgery and related fields have formulated hospital expert experience on perioperative treatment principles of cardiovascular surgery for patients infected with COVID-19. This article summarizes the clinical decision-making of patients requiring cardiovascular surgery after COVID-19 infection, and advises on the corresponding recommendations according to the existing evidence-based medical evidence as well as the actual clinical practice experience of relevant experts. The main content of the article includes special requirements for cardiovascular surgical treatment indications in patients with COVID-19 infection, selection of surgical timing, special requirements of preoperative, intraoperative and postoperative management, etc., which aims to provide COVID-19-infected patients with guidance on rational decision-making when receiving cardiovascular surgery.

ABSTRACT

Objective:To retrospectively analyze the gender differences in the clinical characteristics and perioperative outcomes of patients with type A aortic dissection in our institution.Methods:From January 2019 to January 2020, total 405 patients underwent surgical treatment for type A aortic dissection at Beijing Anzhen Hospital, including extensive aortic repair (total aortic arch replacement combined with stenting elephant trunk implantation) and limited aortic repair. In the entire cohort, male 295 cases, female 110 cases. All measures in this study were expressed as ± s or median(quartiles) and analyzed by Student t test for variables or non- parametric tests; count data were expressed as frequencies and percentages and analyzed by χ2 test and Fisher exact probability test. Independent risk factors were analyzed by logistic multivariate regression. Results:Females were older than males[(53.3 ± 12.4)years old vs. (47.1 ± 11.0)years old, P<0.001] and had significantly higher proportion of diabetes(9.1% vs. 4.1%, P=0.047) and previous cerebrovascular disease (11.8% vs. 5.8%, P=0.038). Females had a lower proportion of total aortic arch replacement combined with elephant trunk implantation (64.5% vs. 82.7%, P<0.001), while aortic cross-clamp time[168.0(144.8, 201.5) minutes vs. 190.0 (163.0, 217.0) minutes, P<0.001] and CPB time[99.0 (79.8, 118.0) min vs. 107.0 (91.0, 126.0) min, P=0.006] were significantly shorter than males. Females had significantly higher rates of pulmonary infection (14.5% vs. 5.8%, P=0.004) and stroke than males (15.5% vs. 8.1%, P=0.030). The difference in the proportion of postoperative deaths between female and male TAAD patients was not statistically significant (3.6% vs. 7.8%). Logistics multivariable regression analysis found that female was an independent risk factor for postoperative stroke ( OR=2.574, 95% CI: 1.198-5.531, P=0.015) and pulmonary infection ( OR=2.610, 95% CI: 1.180-5.772, P=0.018). Conclusion:Gender did not affect mortality after TAAD repair significantly, but females increased the risk of stroke and pulmonary infection after TAAD surgery.

ABSTRACT

Objective:To summarize the clinical data of Sun's procedure(total aortic arch replacement with frozen elephant trunk technique) in the treatment of complex aortic arch disease after previous cardiac surgery.Methods:From January 1, 2018 to December 31, 2020, a total of 55 patients underwent resternotomy Sun's procedure in the Aortic Surgery Center of Beijing Anzhen Hospital, including 41 males and 14 females, with a mean age of(45.4±12.7) years old, were retrospectively analyzed. The indications of primary cardiac surgery included type A aortic dissection, aortic root or ascending aortic aneurysm, heart valve surgery, and coronary heart disease. Indications for reoperation included residual aortic dissection larger than 55 mm in diameter, aortic aneurysm dilation, new type A aortic dissection, anastomotic leakage with symptoms, and pseudoaneurysm. All the operations were performed under general anesthesia and median resternotomy, total aortic arch replacement with the stented elephant trunk implantation and were performed by anterograde unilateral or bilateral cerebral perfusion.Results:There was no intraoperative death, and the postoperative mortality was 9.1%(5/55). The causes of death were 2 cases of low cardiac output, 1 case of respiratory failure, 1 case of cerebral complications, and 1 case of gastrointestinal bleeding. Except death, there were 2 cases of postoperative cerebral complications(2/50, 4%), 5 cases of spinal cord injury(transient paraplegia)(5/50, 10%), the median duration of ventilator use was 17 hours(14-42 h). Other postoperative complications included respiratory insufficiency requiring ventilatory support longer than 48 hours(8/50, 16%), renal insufficiency requiring temporary dialysis(2/50, 4%). The follow-up time was(25.9±11.2) months(10-47 months), during which 1 case died due to cerebral complication, 4 cases underwent total thoracoabdominal aorta replacement, and 1 case underwent anastomotic leakage repair.Conclusion:It is safe and effec to perform Sun's procedure(total aortic arch replacement with frozen elephant trunk technique) in the treatment of complex arch disease after previous cardiac surgery.

ABSTRACT

Objective:To investigate the preoperative ascending aorta diameter in patients with acute type A aortic dissection in the Chinese population, compares and analyze the differences in preoperative blood biomarkers, and evaluate the impact of the preoperative ascending aorta diameter in this part of patients on the short-term prognosis of patients.Methods:A collection of 641 patients with acute type A aortic dissection who were enrolled in the " Acute Aortic Syndrome High-Risk Early Warning and Intervention Study" project from January 2018 to January 2020 were collected. Divide the patients into two groups (group Ⅰ<55 mm, group Ⅱ≥55 mm) according to the preventive intervention value of ascending aorta diameter recommended by the guideline for studying preoperative ascending aorta diameter difference in blood biomarkers and the influence of ascending aorta diameter on the short-term prognosis of patients. All patients had CT scans to assess the diameter of the ascending aorta before operation.Results:In this study, all patients with acute type A aortic dissection had a mean preoperative ascending aorta diameter of (46.9±9.7)mm. The preoperative ascending aorta diameter of all patients was less than 55 mm, accounted for 84.1%. Male patients were more likely to have aortic dissection than females; most patients' age was less than 60 years old. The preoperative blood inflammatory index counts were higher in the ascending aorta diameter ≥55 mm group. However, the long-term prognosis of patients with different ascending aorta diameters before surgery was not apparent in this study. The preoperative survival rate and short-term survival rate of patients with ascending aorta diameter <55 mm were higher than those of other groups, but the difference was not statistically significant.Conclusion:In patients with acute type A aortic dissection, the diameter of the ascending aorta is usually less than 55 mm. Moreover, the blood inflammatory index counts are high in the preoperative ascending aorta diameter ≥55 mm group. Meanwhile, patients with smaller ascending aorta diameter have better survival rate and short-term prognosis.

ABSTRACT

Objective:To explore the correlation between intraoperative cooling temperature and postoperative neurological prognosis in aortic arch surgery.Methods:We observed and collected data from 118 patients who underwent open arch replacement surgery by a single surgeon with mild-to-moderate hypothermic circulatory arrest, from January 2017 to December 2020, in Beijing Anzhen Hospital. According to the bladder temperature during the circulation arrest, 118 patients were divided into 3 groups: T1 group[n=39, (25.58±0.64)℃]; T2 group[n=39, (28.21±0.77)℃]; T3 group[n=40, (30.95±0.97)℃]. Clinical data and operative data were analyzed to assess difference between these 3 groups. Analyze the risk factors of postoperative neurological complications, and explore further the correlation between intraoperative core temperature and postoperative neurological prognosis.Results:Among the 118 patients, the average operation, cardiopulmonary bypass (CPB), block, circulatory arrest, and selective cerebral perfusion (SCP) time were 6.64 h, 188.5 min, 104.19 min, 23.93 min, 28.81 min, respectively. The in-hospital death occurred in 8 patients(6.78%), and permanent neurological dysfunction (PND) in 13 patients(11.02%), transient neurological dysfunction (TND) in 25 patients(21.19%). There was no significant difference in the deaths among the three groups. The incidence of TND and PND in the T3 group was significantly reduced ( P=0.042; P=0.045). In addition, the volume of drainage during the first 24 h and the incidence of re-exploration for bleeding had a relatively obvious decreasing trend ( P=0.005; P=0.012). Through multiple regression analysis, under the adjusted model, the core temperature was independently correlated with the incidence of postoperative PND ( OR=0.51; 95% CI: 0.27-0.97; P=0.0389); in group comparison, the relatively higher core temperature was an independent protective factor for postoperative PND ( OR=0.04; 95% CI: 0.00-0.91; P=0.0434). Conclusion:Our research had preliminary proved that in the open arch replacement surgery, mild hypothermia can reduce the incidence of some complications of deep hypothermia, at the same time improve the prognosis of the neurological prognosis, reduce the incidence of postoperative PND.

ABSTRACT

Objective:To summarize the clinical outcomes and experience of redo median sternotomy on proximal aortic repair. Investigate the relationship between first operation and reoperation, reoperation indications, cardiopulmonary bypass strategy, intraoperative technical details, early and mid-term postoperative results.Methods:There were 28 patients underwent 29 times of redo median sternotomy on proximal aorta from April 2017 to December 2019. There were 23 males (79.3%) with an average age of (45.1±12.7) years (26-79 years), 15 Marfan syndrome (15/29, 51.7%) and 3 Behcet's disease (3/29, 10.3%). The primary operation included aortic valve or mitral valve replacement, Bentall procedure, ascending aortic replacement, simultaneous abdominal aortic replacement, Sun's procedure and coronary artery bypass grafting. The indications for reoperation were: aortic root aneurysm or coronary artery aneurysm, anastomotic leakage, perivalvular leakage due to inflammatory aortic disease, acute or chronic type A aortic dissection and aortic root abscess, aortic arch aneurysm. The surgical methods were Bentall, Cabrol, wheat, aortic valve sparing root replacement with replantation, anastomotic leakage repair, CABG, total arch replacement + stent elephant trunk implantation (Sun's procedure), ascending aorta to abdominal aorta bypass, abdominal aortic replacement.Results:One patient (3.4%) died in hospital because of severe postoperative pulmonary complications, consolidation of both lungs, ARDS and hypoxia. Postoperative low cardiac output was occurred in 2 cases (6.9%), 1 case was cured by ECMO, and 1 case died half a year after operation during follow up period. Re-exploration for postoperative hemorrhage was occurred in three cases (10.3%). Renal failure requires dialysis was 3 cases (10.3%), and transient paresis was 1 cases (3.4%), respectively. All of them were recovered before discharge. During the follow-up period, one patient died of multiple organ failure due to low cardiac output, and one patient underwent total thoracoabdominal aortic replacement. One patient underwent Cabrol for aneurysm of the coronary artery after Bentall procedure. One year later, type A dissection occurred again and Sun's procedure was performed through a median sternotomy.Conclusion:Reoperation of proximal aorta after cardiac and aortic surgery is safe and effective, with good short-term and medium-term results. Comprehensive preoperative evaluation, successful sternotomy, establishment of cardiopulmonary bypass and effective organ protection are the key to successful operation. Patients with aortic diseases, especially Marfan syndrome, are more likely to undergo reoperation. Close follow-up and timely reoperation are necessary to avoid aortic rupture. Sun's procedure is suitable for redo complex arch operation.

ABSTRACT

Objective:Analysis the protective effect of the partial femoral to femoral cardiopulmonary bypass(CPB) on thoracoabdominal aortic aneurysm repair(TAAAR).Methods:From September 2016 to August 2020, 50 cases of TAAAR under partial CPB were performed at our hospital. Thirty males and 20 females with an average age of(40.5±12.4) years old(ranging 21 to 69 years old) were involved. Partial CPB without selective organ perfusion were applied at the early stage. Since November 2019, the adjunct of perfuse the celiac and superior mesenteric artery with warm blood and irrigate the renal artery with 4℃ HTK solution was used in TAAAR, and 25 patients were operated under this adjunct.Results:The average CPB time was(116.9±35.4) min, the lowest central body temperature during the partial CPB was(34.7±0.7)℃. Total early postoperative mortality was 6%(3/50, 3 deaths in partial CPB alone group). Paraplegia occurred in 4 cases(8%), new happened postoperative hemodialysis was in 6 cases(16%). Among the hemodialysis event, 2 cases(8%, 2/25) were in the group with selective organ perfusion, and 4 cases(16%, 4/25) in the group without using the adjunct.Conclusion:Mild hypothermic partial cardiopulmonary bypass combined with selective organ perfusion have protective effects on spinal cord and abdominal organ in patients underwent TAAAR.

ABSTRACT

Objective:To study the risk factors of massive bleeding in patients with acute Stanford type A aortic dissection undergoing moderate hypothermic circulatory arrest repair.Methods:From January 2016 to October 2017, 486 consecutive patients with acute type A aortic dissection were included in the study. All operations were performed with moderate hypothermic circulatory arrest. The basic clinical data of patients were collected retrospectively. Massive bleeding was defined according to definition of Universal Definition of Perioperative Bleeding(UDPB) 4 class and the Blood Conservation Using Antifibrinolytics in a Randomized Trial(BART). Significant variables in univariate analysis were included in multivariate logistic regression analysis. Results:Thirty-four patients(7.00%) died in hospital. A total of one hundred and eighty-seven patients(38.48%) fulfilled criteria of the definition of BART massive bleeding. Forty-five patients(9.26%), 8 patients(1.65%), 114 patients(23.46%), 147 patients(30.25%) and 172 patients(35.39%) were in grade 0, grade 1, grade 2 and grade 4, respectively. With BART as the end point, the result of multivariate logistic regression showed that female gender( OR=3.32, P<0.001), anemia( OR=2.24, P=0.04), clearance creatine≤85 ml/min( OR=1.93, P=0.01), D-dimer level(every 500 ng/ml increase, OR=1.02, P=0.003), cardiopulmonary bypass(CPB) time( OR=1.01, P<0.001), total arch replacement(TAR, OR=2.40, P=0.02) were independent risk factors for massive bleeding, and the time from onset to operation( OR=0.86, P=0.01) was protective factor. With UDPB 4 class as the end point, multivariate logistic regression showed that creatinine clearance≤85 ml/min( OR=2.05, P=0.001), CPB time( OR=1.01, P=0.04) were independent risk factors for massive bleeding. The time from anset to operation( OR=0.85, P=0.002) and Bentall procedure( OR=0.65, P=0.04) were the protective factors. Conclusion:Massive bleeding was more common in acute Stanford type A aortic dissection. Female gender, poor preoperative renal function, high D-dimer level, early time accepting surgical operation and long CPB were independent risk factors. For high-risk patients, simple and effective surgical methods should be taken to reduce the risk of bleeding.

ABSTRACT

Objective:To explore the application of cannulating the ischemic femoral and right axillary artery in Sun’s procedure for acute type A aortic dissection with lower extremity ischemia.Methods:Twelve patients of acute Stanford type A aortic dissection complicated by lower extremity ischemia were analyzed retrospectively between July 2017 and May 2019, and the right axillary and ischemic femoral artery were used for cardiopulmonary bypass. All the 12 patients were male and categorized as the complicated Stanford type A aortic dissection. The mean age was(48.4±8.4)years, and the median time from symptom onset to emergency operation was 24.00(18.50, 43.25)hours. Eleven patients presented with unilateral extremity ischemia, while bilateral extremity ischemia occurred in one. The prosthetic vessel, with a diameter of 8 mm, was anastomosed to the ischemic femoral artery via an end-to-side way. Both the right axillary artery and the prosthetic vessel were cannulated for CPB. For the proximal dissection in this cohort of patients, we performed Bentall procedure in 5 cases, ascending aortic replacement in 3, and the aortic valve commissure reconstruction with ascending aortic replacement in 4. Total arch replacement with stented elephant trunk implantation were carried out for arch and descending aortic lesion in 12 cases.Results:Early mortality was 8.3%(1/12). The time of CPB, aortic clamp, circulatory arrest, and selective cerebral perfusion averaged(204.6±26.3) min, (114.6±16.6) min, (23.4±8.5) min, and(33.5±11.0) min, respectively. Five patients underwent concomitant bypass procedures, including: ascending aorta-bilateral femoral artery bypass in 1, ascending aorta-right femoral artery bypass in 3, ascending aorta-left femoral artery bypass in 1. Acute renal failure with continuous renal replacement therapy occurred in 4 cases, re-thoratomy for hemaostsis in 1, and re-intubation in 1. One patient developed osteofascial compartment syndrome after aortic repair, and consequent left lower extremity compartment fasciotomy was performed. The mean follow-up time was(17.2±7.6)months, and no aortic-related adverse event was detected during follow up.Conclusion:To acute Stanford type A aortic dissection with lower extremity ischemia, cannulating the ischemic femoral and right axillary artery in Sun’s procedure were associated with lower perioperative mortality and better prognosis.

ABSTRACT

Objective:To evaluate the application of moderate hypothermia circulatory arrest(MHCA)with a higher temperature(29℃) and bilateral selective antegrade cerebral perfusion(bSACP) in acute Stanford type A aortic dissection(TAAD] treated by total arch replacement with stented elephant trunk implantation.Methods:From July 2019 to January 2020, fifteen patients of acute TAAD undergoing emergent operations via MHCA with a core temperature of 29℃ and bSACP were analyzed retrospectively(modified group), and 26 patients treated by MHCA(25℃) and unilateral selective antegrade cerebral perfusion(uSACP) during the same period were defined as the traditional group. All cases were complicated type A dissection. The mean age in this cohort was 49 years, and 32 patients(78%) were male. Thirty six patients(87.8%) suffered from arterial hypertension. The proximal manipulations included: aortic sinus repair in 13 cases(31.7%), ascending aortic replacement in 29(70.7%), Bentall in 12(29.3%). Total arch replacement with stented elephant trunk implantation was performed in all cases.Results:The in-hospital death occurred in 2(4.9%), and cerebral infarction in 3(7.3%), transient neurologic deficit in 5(12.2%), paraplegia in 2(4.9%). The ratios of above-mentioned adverse events in the traditional and modified group were[2(7.7%) vs. 0, P=0.524], [3(11.5%)vs. 0, P=0.287], [4(15.4%) vs. 1(6.7%), P=0.636], [1(3.8%) vs. 1(6.7%), P=1.000] respectively. The major adverse events in the modified group were transient neurologic deficit and paraplegia in 1 each. Compared with the traditional group, the time of operation, CPB, cardiac arrest, circulatory arrest of the lower part, anterograde low flow cerebral perfusion, mechanical ventilation and ICU stay was shorter. The drainage of 48 hours after surgery was less also. The differences in new acute renal failure requiring CRRT and re-sternotomy for bleeding between groups were not statistical significance. Conclusion:The early results of MHCA(29℃) and bSACP applied in total arch replacement with stented elephant trunk implantation for acute TAAD were satisfactory. The time of mechanical ventilation and ICU stay was shorter in the modified group, and the drainage of 48 hours after surgery was less also.

ABSTRACT

Objective:To evaluate the clinical value of 18F-fluorodexoyglucose (FDG) PET/CT in distinguishing benign from malignant tumors in patients with cardiac tumors. Methods:Between January 2015 and September 2018, 18F-FDG PET/CT was performed in 3 678 patents in Beijing Anzhen Hospital, and 51 of them (51/3 678, 1.39%) were diagnosed as cardiac tumors. Finally, 28 patients (10 males, 18 females; mean age (52±14) years, age range: 18-84 years) with pathological results were included. According to pathological results, patients were divided into 4 groups: group 1 with primary benign cardiac tumor ( n=9), group 2 with primary malignant cardiac tumor ( n=9), group 3 with lymphoma ( n=6) and group 4 with secondary malignant cardiac tumor ( n=4). All patients underwent early (60 min) 18F-FDG PET/CT imaging and 22 patients (6, 7, 6, 3 patients in group 1, group 2, group 3, group 4 respectively) underwent delayed (120 min) imaging. The maximum standardized uptake value (SUV max) and target/backgroud ratio (TBR) of 4 groups in early imaging and delayed imaging were calculated and compared with one-way analysis of viariace and Scheffe Post-hoc test. TBR were calcualted as SUV max/mean standardized uptake value (SUV mean) in the liver. Receiver operating characteristic (ROC) curve analysis was also performed. Results:SUV max during early imaging, defined SUV max(early), was 2.6±1.5, 9.9±4.0, 20.5±6.1, 9.2±5.8 in group 1-4 respectively ( F=21.39, P<0.01), the value of group 1 was lower than that of group 2 and 3, and the value of group 3 was the highest (all P<0.005). TBR early was 1.1±0.6, 4.1±1.6, 9.4±2.6, 3.7±2.0 in the 4 groups ( F=29.15, P<0.01), the value of group 1 was lower than that of group 2 and 3, and the value of group 3 was the highest (all P<0.005). SUV max in delayed imaging (SUV max(delay)) was 2.4±1.2, 11.0±5.9, 25.8±7.7, 13.7±7.7 respectively in the 4 groups ( F=16.01, P<0.01). TBR delay was also significantly different among the 4 groups (1.3±0.7, 5.5±2.9, 14.4±4.9, 7.9±5.0; F=14.78, P<0.01), the value of group 3 was higher than that of group 1 and 2 (all P<0.05). ROC curve analysis showed optimal cut-off values for indicating malignancy were: SUV max(early)=4.2, TBR early=1.6, SUV max(delay)=4.6, TBR delay=1.9. The corresponding sensitivities, specificities, accuracies were 19/19, 8/9, 96.4%(27/28); 19/19, 7/9, 92.9%(26/28); 16/16, 6/6, 100%(22/22); 16/16, 5/6, 95.5%(21/22), respectively. Conclusions:18F-FDG PET/CT imaging can accurately diagnose malignant cardiac tumors. Delayed imaging can further improve the accuracy for diagnosis of malignant cardiac tumors.

ABSTRACT

Objective:To investigate the expression and significance of T helper cell 17 (Th17), soluble intercellular adhesion molecule-1 (sICAM-1) and coagulation function in patients with infectious endocarditis(IE).Methods:From December 2016 to December 2018, IE patients in Beijing Anzhen Hospital Affiliated to Capital Medical University who met the inclusion criteria were selected for cardiac surgery to analyze prospectively, 38 IE patients were selected as the observation group, and 30 healthy people were selected as the control group.The concentrations of serum Th17 related factors (IL-1β, IL-6, IL-17 and IL-21), sICAM-1 and coagulation index(P selectin(sP-SLT)) were measured by enzyme-linked immunosorbent assay(ELISA) and the difference between the two groups were statistically analyzed.Results:The concentrations of serum IL-1β, IL-6, IL-17 and IL-21((29.88±6.49), (14.89±3.31), (21.89±3.01), (563.26±67.36) ng/L) in the observation group were significantly higher than those in the control group((16.56±4.11), (7.52±2.34), (12.91±1.01), (423.38±56.49) ng/L)(all P<0.05). The level of serum sICAM-1 and sP-SLT ((1 247.57(581.39, 1 794.66) μg/L, (60.29±6.61) mg/L)in the observation group were significantly higher than those in the control group((837.28(405.68, 954.47) μg/L, (27.37±5.56) mg/L), and the difference was statistically significant( Z=12.37, t=22.30, all P<0.05). The level of serum IL-1β, IL-6, IL-17 and IL-21 in patients with postoperative infective endocarditis((16.19±4.07), (7.73±2.40), (13.83±0.94), (425.33±52.12) ng/L) were significantly lower than those before operation((29.88±6.49), (14.89±2.31), (21.89±3.01), (563.26±67.36) ng/L), and the differences were statistically significant(t values were 11.02, 13.25, 15.76, 9.98, all P<0.05). The levels of sICAM-1 and sP-SLT1 in patients with postoperative infective endocarditis((901.46(472.15, 1276.58) μg/L, (30.70±5.31) mg/L) were significantly lower than those before operation((1 057.26±463.06) μg/L, (60.29±6.61) mg/L)and the differences were statistically significant( Z=11.16, t=21.51, P<0.05). Conclusion:Th17 related factors, sICAM-1 and sP-SLT were highly expressed in IE patients, and the concentrations of these factors decreased after operation, suggesting that the above factors may be used as related factors for the diagnosis and prognosis of IE patients.
