RESUMO
Objective:To investigate the relationship of delayed cardiac tamponade (CT) after left atrial appendage closure (LAAC) in atrial fibrillation (AF) patients and implanted occluders and adjacent anatomical structures.Methods:This study was a retrospective study. Thirteen AF patients with LAAC complicated with delayed CT and with concurrent emergency pericardiocentesis drainage in Zhoupu Hospital, Shanghai University of Medicine & Health Sciences from August 2016 to June 2021 were selected. The follow-up time was (16±12) months. The clinical data of these patients were retrospectively analyzed, including the relationship between the left atrial appendage and pulmonary artery, vein anatomy by left atrium computed tomography angiography (CTA) before and after LAAC.Results:Thirteen patients with delayed CT were treated by pericardiocentesis and drainage after LAAC and aged (72.1±8.3) years, and 7 patients were male, Six patients received cryoablation simultaneously. The classification types of left atrial appendage included cauliflower and chicken wing types were 8 and 5 respectively. The seal plate diameter of the lobe-and-disc devices was (29.5±2.8)mm; 10 patients had cardiac CTA reviewed. The occluder was attached to pulmonary artery in 8 patients, attached to left superior pulmonary vein only in one patient, and attached to pulmonary artery and left superior pulmonary vein in one patient. The prognosis was good except one patient who died 2 days after LAAC.Conclusions:Delayed CT after LACC is closely related to the location of left atrial appendage adjacent to pulmonary artery and left superior pulmonary vein, and is related to larger occluder and anchor hook.
RESUMO
Objective:To investigate the relationship between systemic immune-inflammation index (SII) and the prognosis of esophageal cancer patients treated with radical radiotherapy and to predict the prognosis of the patients using the SII combined with clinical staging.Methods:A retrospective analysis was conducted for 248 patients with esophageal cancer who were admitted to the Department of Radiotherapy in the Fourth Hospital of Hebei Medical University between 2014 and 2016. These patients included 146 males and 102 females, with a median age of 67 years. Among them, 134 patients received concurrent chemotherapy and 114 patients received radiotherapy alone. The SII before radiotherapy was defined as platelet count × neutrophil count/lymphocyte count. The patients were divided into a low-SII group and a high-SII group according to the optimal cutoff value of pretreatment SII determined by the receiver operating characteristics (ROC) curve. Survival analysis was calculated using the Kaplan-Meier method, and the Cox proportional hazards model was used for multivariate analysis. For these patients, the prognosis effects and the predictive value for survival of different SII levels combined with TNM staging were compared.Results:According to the ROC curves, the optimal cutoff value of SII before radiotherapy was 740.80. Based on this number, the patients were divided into a low-SII group (< 740.80, 150 cases) and a high-SII group (≥ 740.80, 98 cases). The objective response rate of the low-SII group was significantly higher than that of the high-SII group (86.0% vs 75.5%, χ2=4.39, P=0.036). The 1-, 3-, and 5-year overall survival (OS) rates of the low-SII group were 78.6%, 45.6%, and 32.3%, respectively. These rates were significantly higher than the corresponding rates of the high-SII group, which were 71.0%, 28.3%, and 16.4% ( χ2=11.22, P=0.001), respectively. Moreover, the 1-, 3- and 5-year progression-free survival (PFS) rates of the low-SII group were 67.0%, 36.9%, and 32.0%, respectively. Again, these rates were significantly higher than those of the high-SII group, which were 45.5%, 17.5%, and 12.5% ( χ2=15.38, P < 0.001), respectively. Multivariate analysis showed that TNM staging, treatment method, and SII were independent prognostic factors for OS and PFS ( HR=1.39-1.60, P<0.05). Patients with low SII and early clinical staging had a better prognosis than other subgroups ( χ2=13.68, 13.43, P=0.001). The area under curve (AUC) of SII combined with TNM staging (0.70) was higher than that of SII (0.63) and TNM staging (0.62) ( Z=2.48, 2.57, P < 0.05). Conclusions:Pretreatment SII has a high predictive value for the prognosis of esophageal cancer after radiotherapy, and higher SII indicates a worse prognosis. Thus, combining SII with TNM staging can improve the prediction accuracy of the prognosis of esophageal cancer patients.
RESUMO
Objective:To investigate the relationship between Onodera′s prognostic nutritional index (PNI) and prognosis of patients with esophageal squamous cell carcinoma (ESCC) after definitive chemoradiotherapy or radiotherapy, aiming to provide a convenient, effective and accurate predictive indicator for evaluating the long-term survival of patients after treatment.Methods:Clinical data of 231 ESCC patients treated with definitive chemoradiotherapy or radiotherapy at the Fourth Hospital of Hebei Medical University from 2013 to 2015 were retrospectively analyzed. The PNI values of each patient at different radiotherapy periods were calculated and the ROC curve was used to determine the optimal cutoff value of PNI before radiotherapy, 231 patients were divided into the better-nourishment group ( n=86) and worse-nourishment group ( n=145). Kaplan- Meier method was used for survival analysis. Cox proportional hazards model was utilized to analyze the relationship between different nutritional status and prognosis. The short-term clinical efficacy and incidence of acute toxicities were statistically compared between two groups. Results:The mean values of PNI before, at week 3, week 6 and 1 month after radiotherapy were48.68±5.08, 39.68±4.87, 43.74±4.89 and48.31±4.92, respectively. The optimal cutoff value of pretreatment PNI was 49.25, the area under the curve (AUC) was 0.655, the sensitivity and specificity were 68.6% and 60.9%, respectively. The 5-year overall survival (OS) and progression-free survival (PFS) rates in the better-nourishment group (PNI≥49.25) were 36.0% and 31.3%, significantly better than 19.3% and 18.6% in the worse-nourishment group (PNI<49.25)( P=0.001, P=0.039). Multivariate analysis showed PNI before the therapy was an independent prognostic factor for OS ( P=0.021). Stratified analysis demonstrated that Stage Ⅰ/Ⅱ and concurrent chemotherapy patients in the better-nourishment group all obtained significantly better OS than their counterparts in the worse-nourishment group ( P=0.007, P=0.004). In addition, the objective response rate in the better-nourishment group was significantly higher than that in the worse-nourishment group ( P=0.047), whereas the incidence of ≥3 grade radiation esophagitis was lower than that in the worse-nourishment group ( P=0.060). Conclusions:Pretreatment PNI is a convenient and reliable indicator for predicting the long-term survival of ESCC patients after definitive chemoradiotherapy or radiotherapy. Patients with higher PNI have relatively better prognosis and radiotherapy tolerance, especially in those with early stage or concurrent chemotherapy.
RESUMO
Objective@#To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES).@*Methods@#This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio.@*Results@#A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score.@*Conclusion@#The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.
RESUMO
Objective@#To investigate the clinical features and change trend of patients with acute coronary syndrome(ACS) undergoing emergent percutaneous coronary intervention(PCI).@*Methods@#In this retrospective study, we retrieved all medical records of 4 907 ACS patients who underwent emergent PCI in Fuwai hospital from January 1,2010 to December 31,2016. We analyzed the clinical features and change trend in these patients. According to clinical diagnosis, patients were grouped as ST-elevated myocardial infarction(STEMI) group (3 719 cases) and NSTE-ACS group (patients with non-STEMI and unstable angina, 1 188 cases).@*Results@#The ACS patients were aged (59.5±11.8) years old. There were 3 772 males and 1 135 females. The annual number of ACS patients underwent emergent PCI increased from 412 patients in 2010 to 1 067 patients in 2016. The number of NSTE-ACS patients increased from 11.4% (47/412) in 2010 to 26.5% (283/1 067) in 2016. Compared with STEMI group, patients in NSTE-ACS group were significantly older ((61.2±10.9) years old vs. (58.9±12.1) years old,P<0.01).The percent of female patients (30.1% (358/1 188) vs. 20.9% (777/3 719), P < 0.01), history of hypertension (69.1% (821/1 188) vs. 60.4% (2 248/3 719,P <0.01), previous PCI (25.8% (307/1 188) vs. 12.4% (461/3 719), P <0.01), and previous coronary artery bypass grafting (3.0% (36/1 188) vs. 1.0% (37/3 719), P <0.01) were all significantly higher in NSTE-ACS group than in STEMI group. On the other hand, NSTE-ACS patients presented less chronic renal failure (2.9% (35/1 188) vs. 4.3% (173/3 719), P <0.05) and hepatic dysfunction (8.5% (101/1 188) vs. 13.3% (495/3 719), P<0.01) as compared to ACS patients. In coronary angiography, NSTE-ACS patients had a higher prevalence of left-main disease (14.0% (166/1 188) vs. 7.8% (291/3 719), P<0.012 5) and triple vessel disease (47.8% (568/1 188) vs. 43.5% (1 619/3 719), P<0.012 5). There were no differences in prevalence of diabetes mellitus (31.9% (1 187/3 719) vs. 34.8% (414/1 188),P>0.05) and acute renal failure (0.1% (38/3 719) vs. 0.6% (7/1 188),P>0.05) between STEMI group and NSTE-ACS group.@*Conclusions@#This single center retrospective analysis reveals that there is an increasing trend of NSTE-ACS patients from 2010 to 2016. Furthermore, there are more high-risk clinical characteristics in NSTE-ACS patients than in STEMI patients.
RESUMO
Objective To explore the relationship between optical coherence tomography (OCT) characteristics and peripheral blood leukocyte count in patients with acute myocardial infarction(AMI). Methods A total of 33 patients with AMI hospitalized in Fuwai Hospital for primary percutaneous coronary intervention were consecutively enrolled,and underwent intracoronary OCT procedures after manual aspiration of coronary thrombus. Demographic data, risk factors, procedural and OCT data, past medical history and perioperative laboratory findings were collected in all patients. Results The lymphocyte count,monocyte count and basophil count were significantly higher in the patients with fibrous cap thickness ≥ 65 μm than in those patients with fibrous cap thickness ≤ 65 μm. Patients presenting with cholesterol crystallization had lower eosinophil count than those patients with crystallization-free [(0.04±0.06)×109/L vs.(0.10±0.09) ×109/L,P =0.028]. In addition,the former had significantly higher to neutrophil lymphocyte ratio than the latter [(8.35±6.13)vs.(4.97±2.01), P =0.020]. Higher monocyte count was found in the patients with calcified plaque (P <0.05). Platelet to lymphocyte ratio was significantly increased in the patients with macrophage infiltration [(165.72±85.93)vs.(113.47±19.13),P <0.05]. The leukocyte count,neutrophil count and monocyte count showed the treat of elevation as the number of OCT characteristics increased,but only the elevation of monocyte count had statistical significant level (P = 0.014). Conclusions Peripheral blood leukocyte count seems to be associated with OCT characteristics of plaque rupture in patients with acute myocardial infarction,suggesting the potential role of inflammation in plaque rupture.
RESUMO
Objective Ticagrelor-related dyspnea may affect the medication adherence of patients with coronary artery disease.This study aims to assess the impact of ticagrelor adherence on 1-year cardiovascular outcomes in pateints with stable coronary artery diseases (SCAD).Methods This study includes the patients with SCAD from Fuwai hospital who discharged with ticagrelor between Jan.2015 to Jun.2015.We collected data of clinical characteristics and ticagrelor adherence from these patients by reviewing the electronic medical records and personnel interview.Follow-up was performed at 6 and 12 months by telephone interview or office visits.Results A total of 155 patients with SCAD were enrolled,of whom 122 (78.7％) were males with a mean age (57.0 ± 10.0) years.Among them,50 (32.3％) patients have a history of myocardial infraction and 106 (68.4％) patients had angiographic confirmed left main and/or multivessel disease.Forty-six patients (29.7％) with SCAD prematurely stopped ticagrelor within 12 months,while 25 (16.1％) patients switched from ticagrelor to clopidogrel.Hemorrhagic events and locally unavailable ticagrelor were the major reasons causes of the premature discontinuation of ticagrelor.Univariate analysis showed age,body mass index (BMI),hypertention and locally unavailable ticagrelor as relative factors for early ticagrelor discontinuation after discharge.Multivariate analysis revealed unavailable drug locally (OR 0.25,95％ CI 0.09-0.69) and elderly patients (OR 4.13,95％ CI 1.40-12.19) were risk factors for low persientence or premature ticagrelor discontinuation.Conclusion This study showed poor ticagrelor adherence in patients with SCAD after discharge.Locally unavailable ticagrelor and elderly patients were strong predictors of poor ticagrelor adherence.Discontinuation to ticagrelor prematurely may not have impact on adverse cardiovascular outcomes.

RESUMO
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.
RESUMO
Objective To explore the effect of prehospital 12-lead electrocardiogram (ECG) and transtelephonic notification on door-to-balloon time in patients with ST-segment elevation myocardial infarction (STEMI). Methods Four hundred and two patients with STEMI who underwent primary PCI from January 2006 to December 2007 in Beijng Anzhen Hospital were analyzed. They were divided into 3 groups: 137 patients without prehospital ECG (group A), 176 patients with prehospital ECG (group B) and 89 patients with prehospital ECG and early transtelephonie notification (group C). Door-to-balloon time and in-hospital mortality were compared among the groups. Results There were no significant differences in age, sex, past medical history and infarcted area among three groups. Compared with group A, patients in group B and group C had much shorter door-to-balloon time (96 minutes and 86 minutes vs. 113 minntes in group A, all P<0. 01). No difference was found in in-hospital mortality among three groups (2. 9% vs. 2.3% vs. 2. 2%, P> 0. 05). Conclusions Prehospital ECG and early transtelephonic notification can significantly shorten door-to-balloon time in patients with STEMI. Coordinated system including prehospital ECG and transtelephonie notification is proved to be feasible and effective.
RESUMO
Objective: To evaluate the safety and efficacy of overlapping Sirolimus-eluting stents (SES) in very long lesions during primary percutaneous coronary intervention (PCI) in patients with ST-elevated myocardial infarction (STEMI).Methods: A total of 297 consecutive patients with STEMI underwent primary PCI from January to December 2007 in our hospital were studied.We identified the patients who had 2 or more SES implanted in single long lesion with a single procedure.6 months angiographic and clinical follow-up was performed.The incidences of restenosis and major adverse cardiac event (MACE) during hospitalization and at the follow-up time were analyzed.Results: We identified 31 patients with 31 long lesions who had been implanted more than 2 stents.A median of 2.1 stents were implanted, the median lesion length was 47.2±10.3mm and a median implanted stents'length was 53.2±10.5 mm.6 months clinical follow up rate was 100% and 6 months angiographic follow-up rate was 74.2%, respectively.The incidence of MACE was 8.7% which including target lesion revascularization (TLR).No cardiac death and no fatal myocardial infarction were found.Conclusion: Implantation of SES for very long target lesions seemed to be safe and effective in patients with ST elevated myocardial infarction.Its long-term safety and effectiveness should be further investigated.
