Objectives:This study aimed to explore the association between perceived mental stress (MS), lymphocyte subset variations, and coronary lesion severity in patients with coronary artery disease (CAD).Methods:Patients with CAD were enrolled in this study from September 2023 to May 2024. Perceived Stress Scale-14 (PSS-14) was used to evaluate MS during the last 1 month. Lymphocyte subsets were analyzed, including the percentage and absolute counts of CD3 +, CD3 +CD4 +, CD3 +CD8 +, CD3 -CD19 +, CD3 -CD56 +16 +, and the Th/Ts ratio. Statistical analysis was conducted using SPSS 24.0. Results:This study recruited patients with 323 CAD, with an average age of 61 (56, 68) years, including 203 males and 120 females. According to the PSS-14, a score of 14-42 and 43-70 were categorized as normal and increased MS, respectively. Patients with CAD with increased MS had significantly higher Gensini scores than those with normal MS [37(19,64) vs. 28(12,50), Z=-2.19, P=0.029]. Male CAD patients with increased MS exhibited significantly higher Gensini scores [39(20, 58) vs. 26(12, 45), Z=-2.37, P=0.018], levels of CD3 +CD8 +%[28.3%(23.6%,36.6%) vs. 25.9%(21.0%,32.4%), Z=-2.05, P=0.041], and CD3 +CD8 +absolute value [485 (346, 675) vs. 396 (309, 510) cells/μl, Z=-2.55, P=0.011] than those with normal MS. In male patients with CAD, a positive correlation was observed between Gensini scores (correlation coefficient: 0.181, P=0.011), PSS-14 scores, and CD3 +CD8 +absolute value (correlation coefficient: 0.162, P=0.038). Conclusion:This study reveals a positive correlation between MS and coronary stenosis severity, with notable sex differences. In male patients with CAD, higher levels of MS are associated with more severe coronary stenosis. The potential underlying mechanism may involve the regulation of lymphocyte subsets .

Objective:To investigate the clinical efficacy of arthroscopic double-row double-pulley technique in the treatment of Ideberg type IA scapular glenoid fracture.Methods:A retrospective case series study was conducted to analyze the clinical data of 16 patients with Ideberg type IA scapular glenoid fracture admitted to Jiading Branch of Shanghai General Hospital from January 2018 to December 2021, including 10 males and 6 females, aged 25-65 years [(42.9±5.1)years]. The patients were treated with arthroscope-assisted reduction and double-row double-pulley technique. The operation time was recorded. Three-dimensional reconstruction of the shoulder joint with CT was performed to assess fracture displacement and healing. Modified University of California Los Angeles (UCLA) score and Constant-Murley score were used to evaluate shoulder function and Visual Analogue Scale (VAS) score was used to evaluate pain before surgery, at 3, 6, 12 months after surgery and at the last follow-up. The complications were observed.Results:All the patients were followed up for 12-36 months [(20.3±4.4)months]. The operation time was 60-90 minutes [(74.7±8.9)minutes]. Three-dimensional construction of the shoulder joint with CT performed at 3 months after surgery showed that there was no fracture re-displacement and all the patients had bone union. The modified UCLA score, Constant-Murley score and VAS score at 3 months after surgery were (30.4±0.4)points, (84.3±1.4)points and 2.0(1.3, 3.0)points, respectively, which were significantly improved compared with those before surgery [(21.1±0.5)points, (56.4±1.3)points and 5.0(5.0, 6.0)points respectively] ( P<0.05). The modified UCLA score, Constant-Murley score and VAS score at 6 months after surgery were (33.1±0.4)points, (91.0±0.5)points and 1.0(1.0, 2.0)]points respectively, which were significantly improved compared with those at 3 months after surgery ( P<0.05). The modified UCLA score, Constant-Murley score and VAS score at 12 months after surgery were (33.5±0.3)points, (92.6±0.6)points and 1.0(0.3, 1.8)points respectively, showing no significant differences from those at 6 months after surgery ( P>0.05). The modified UCLA score, Constant-Murley score and VAS score at the last follow-up were (33.8±0.8)points, (93.7±1.8)points and 1.0(0.0, 1.0)points respectively, with no significant differences from those at 12 months after surgery ( P>0.05). There were no complications such as wound infection, neurovascular injury or shoulder stiffness after surgery. Conclusion:Arthroscopic double-row double-pulley technique for the treatment of Ideberg type IA scapular glenoid fracture has a short operation time, a high fracture healing rate, good shoulder function recovery, and pain relief, with no common complications.

Objective:To explore the prognosis efficacy of psycho-cardiological therapy and management on patients with coronary atherosclerosis disease (CAD).Methods:This was a clinical randomized controlled study. This study included inpatients with CAD at the cardiology department in Beijing Anzhen Hospital, Capital Medical University from August 2021 to January 2024. The patients enrolled in this study were asked for basic information, and received measurements for depression, anxiety, sleep quality and living quality by the scales of Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder scale-7 (GAD-7), Athens Insomnia Scale (AIS), EuroQol 5-dimension 5-level (EQ-5D-5L) respectively. The patients were randomly grouped into a regular treatment group and a psycho-cardiological treatment group which included WeChat management or antidepressant/antianxiety medical therapy according to the situation. After the patients discharging from hospital for 2, 4, 12, 24, 48, 72, and 96 weeks, professional cardiovascular doctors would follow up by telephone, WeChat, and outpatient department, including scales (2-48 weeks), and cardiac events (2-96 weeks). Kaplan-Meier survival curve and multivariate Cox proportional hazards model were used for analyzing the association between psycho-cardiological treatment and cardiac events.Results:This study recruited a total of 552 patients with CAD, aged 61.0(54.0, 67.0) years, and 379 (68.7%) were male. There were 279(50.5%) in the regular treatment group and 273(49.5%) in the psycho-cardiological treatment group. After treatment for 4, 12 and 48 weeks, the PHQ-9 score in psycho-cardiological was significantly lower than the regular treatment group; After treatment for 12 weeks, the EQ-5D-5L effective value in psycho-cardiological group was higher than the regular treatment group; After treatment for 2, 4, 12, 24 and 48 weeks, the EQ-5D-5L VAS score in psycho-cardiological group was higher than the regular therapy group (all P<0.05). The Kaplan-Meier survival curve showed that, during the different follow-up periods, the rate of cardiac events in psycho-cardiological treatment group was lower than regular treatment group (log-rank P<0.001). The multivariate Cox proportional hazards model adjusted the factor of age, the psycho-cardiological treatment contributed to reducing the cardiac events rate by 80.3% ( HR=0.197, 95% CI: 0.067-0.582, P=0.003). Conclusion:Psycho-cardiological treatment is beneficial for improving psychological stress, living quality, and reducing cardiac events, and helps to improve prognosis and psycho-cardiological rehabilitation in CAD patients.

The consensus aims to provide criteria for the diagnosis and treatment of OMSI in China so as to improve the level of OMSI treatment.

Objective: To compare the safety of continued warfarin therapy and bridging anticoagulation therapy during hospital stay in patients undergoing percutaneous coronary intervention (PCI). Methods: We retrospectively analyzed patients on warfarin therapy referred for PCI in Beijing Anzhen Hospital from January 2008 to December 2016. The patients were divided into continued warfarin therapy (n=195) or bridging anticoagulation therapy (n=311) groups. After Propensity Score Matching, data from matched patients (n=123 in each group) were analyzed. Bleeding complications and major adverse cardiac events including death, myocardial infarction, target vessel revascularization, and stent thrombosis were assessed. Results: There were no significant difference in the rate of death (2.4%(3/123) vs. 1.6%(2/123),P=0.54), acute myocardial infarction (4.1%(5/123) vs. 4.9%(6/123), P=0.78),re-revascularization (0.8%(1/123) vs. 1.6%(2/123),P=0.16), stent thrombosis (1.6%(2/123) vs. 1.6%(2/123),P=1.00) and stroke between the two groups. Prevalence of minor bleeding complications was significantly higher in the bridging therapy group (15.4%(19/123) vs. 9.8%(12/123),P=0.01). Rate of access-site complications (hematoma:4.1%(5/123) vs. 2.4%(3/123),P=0.20; pseudoaneurysm:2.4%(3/123) vs. 2.4%(3/123),P=1.00; arteriovenous fistula:0.8%(1/123) vs. 1.6%(2/123),P=0.09; and retroperitoneal hematoma:0(0/123) vs. 0.8%(1/123),P=0.23) were similar between the two groups. Conclusion For patients receiving chronic warfarin therapy, the uninterrupted oral anticoagulant treatment is as safe as bridging therapy in PCI patients.

Objective To evaluate the impact of cardiovascular risk factors on index of microvascular resistance (IMR)and coronary flow reserve (CFR) and to explore the characteristics of IMR and CFR and the relationship between IMR and angiographic features in patients with intermediate coronary stenosis and chest pain.Methods Fractional flow reserve (FFR),CFR,and IMR were measured in patients who underwent invasive coronary angiography with 40％-70％ stenosis by visual assessment.All patients with FFR＞0.75 were enrolled and grouped with the cut-off points of IMR≥25 and CFR≤2.0.Patients with IMR≥25 were group H,including two sub-groups (high IMR-low CFR,group H1 and high IMR-high CFR,group H2),while those with IMR＜25 were group N.The thrombolysis in myocardial infarction (TIMI) frame were counted.Results A total of 34 patients with FFR＞0.75 were enrolled with 61.8％(21 cases) of males and 38.2％ (13 cases) of females.The mean age was (57.3±8.1) years old.High IMR accounted for 47.1％ of all cases.There was significant difference between group H and N in TIMI frame (33.0 vs.20.8,P=0.031).There were significant differences between group H1 and H2 in homocysteine (17.8 μmol/L vs.12.0 μmol/L,P=0.005) and IMRcorr (58.0 vs.36.1,P=0.002).IMRcorrwas correlated to TIMI frame (r=0.40,P=0.012) for all cases.The sensitivity and specificity of inferring IMR≥35.3 by TIMI frame were 0.75 and 0.65 (P=0.049) with TIMI frame over 40.5.Conclusions High IMR may be one of the reasons for chest pain in patients with intermediate coronary stenosis.There is no correlation between vascular risk factors and IMR or CFR,while there is positive correlation between TIMI frame and IMR.The specificity is 65％ for inferring IMR rise with TIMI frame over 40.5.

Objective To explore the mechanisms of ligament of Marshall (LOM) initiat and sustain atrial fibrillation (AF).Methods The electrophysiologic properties of canine LOM were investigated using multipolar catheter mapping(normal canines,n =4,group A;AF canines,n =5,group B).The programmed stimulation were performed in the LOM,PV-left atrium(LA)junction and LA,respectively.Activations maps of LOM were analyzed from episodes of spontaneous onset of AF and initiation of induced AF by a single extrastimulus.The effectives refractory period of each part was compared and statistically analyzed among three parts in each group and between the two groups.LOM were cutted with surgical incision technology.The inducing rate of AF and the mapping rate of double potential and fragmented electrocardiogram were compared and statistically analyzed pro and post isolation of LOM.Results The incidence of abnormal potential of LOM in the two groups was significantly different(P ＜0.01),re-entry cycle(group A 25％ vs.B group 80％),tachycardia(group A 25％ vs.B 100％),double potential(group A 25％ vs.group B 80％),fragmentation potential(group A 25％ vs.group 80％).There was a significant difference in the rate of LOM tachycardia induction before and after LOM intervention in group B (P ＜ 0.05,before 100％ vs.after 20％).Conclusion There are two possible mechanisms of LOM involved in the occurrence and maintenance of AF:one is that LOM induces AF through spontaneous excitation,the other is that LOM participates in the reentry of left atrium and pulmonary vein in the form of bypass to induce and maintain AF.

Objective To discuss the early diagnosis and interventional therapy of acute renal infarction.Methods The diagnosis and therapy of 5 cases of acute renal infarction were retrospectively analyzed.There were 4 male and 1 female patients,aged 38-68 years.The symptoms were severe back pain or upper abdominal pain,with or without nausea and vomiting and the time to hospital was 1 to 16 h.Four cases had rheumatic heart disease and 4 cases had artrial fibrillation history.The lab assay results: WBC 8.9-15.8 × 109/L,urine RBC-to + + +,albumin + to + + +,serum creatinin 66-216 μmol/L,serum LDH 350-920 U/L.The doppler ultrasound and CT scan showed large infarction in 3 cases and focal infarction in 2 cases.Percutaneous arteriography,thrombolytic therapy and thrombosuction via catheter were applied promptly.Results The 5 cases were diagnosed and treated timely and effectively.The emboli were cleared.Four patients were followed up for 3-12 months.The creatinin recovered to 53-122 μmol/L,and the blood perfusion of the infarction lesion was satisfactory.Conclusions Early diagnosis and interventional therapy is important for achieving satisfactory recovery of the acute renal infarction.Three dimensional CT angiography could conduce to early diagnosis and follow-up.Thrombosuction via catheter plus thrombolytic therapy is efficient for greater embolus.

Objective To evaluate the safety and efficacy of overlapping sirolimus-eluting stent (SES) for long lesions during primary percutanous coronary intervention(PCl) in elderly patients with ST-segment elevation myocardial infarction (STEMI).Methods Seven hundred and seventy-five elderly patients with STEMI who underwent primary PCI were enrolled and followed up. Patients with two or more SES implanted for long lesions during PCI were taken as long lesion group and patients with single stents implanted were regarded as control group. The safety endpoints were in-hospital and follow-up death and stem thrombosis, and the clinical endpoints were the incidence of restenosis and target vessel revascularization rate during in-hospital follow-up and 6 months" follow-up.Results Among 775 patients, 62 patients had 64 long lesions. The average number of stents was 2. 2, and the average lesion length and stent length implanted were (45.3±10. 4)mm and (52.2±11.0)mm, respectively. During the 6 months' follow-up, the incidence of angiographically documented stent thrombosis were 1.6% in long lesion group and 1.1% in control group, respectively. No death or myocardial infarction occurred in two groups. There was no significant difference in the incidence of restenosis and target vessel revascularization rate between long-lesion group and control group (8. 1 vs. 4.8%, 6.9% vs. 3. 7%, both P>0.05). Conclusions Overlapping implantation of homemade SES is safe and effective for STEMI patients with long lesions in short-term period.
