ObjectiveTo investigate the effectiveness of establishment of chest pain center and optimized process in the diagnostic and treatment progress and short-term prognostic value of acute non-ST segment elevation myocardial infarction (NSTEMI) patients. MethodsThis was a retrospective study. We included NSTEMI patients admitted in the Emergency Department in our hospital, 41 patients admitted before the establishment of the chest pain center (April 2015) were included as group A (30 males and 11 females at age of 64.7±11.8 years), 42 patients after the establishment of the chest pain center (April 2016) as group B (31 males and 11 females at age of 64.6±11.8 years), and 38 patients after the establishment of the chest pain center (April 2017) as group C (30 males and 8 females at age of 62.6±10.0 years). The clinical outcomes of the three groups were compared.ResultsThe time from admission to electrocardiogram was 20.0 (17.0, 25.5) min in the group A, 4.0 (2.8, 5.0) min in the group B, and 3.0 (2.0, 4.0) min in the group C (P<0.001). The first doctor's non-electrocardiogram advice time was 13.0 (10.0, 18.0) min, 9.5 (6.8, 15.3) min, and 9.0 (7.0, 12.0) min (P=0.001) in the three groups, respectively. The diagnostic confirmed time was 139.4±48.5 min, 71.1±51.5 min, 63.9±41.9 min (P<0.001). The proportion of patients receiving emergency dual anti-platelet load dose treatment was 53.1%, 70.0%, 100.0% (P=0.001), respectively. The time of receiving emergency dual anti-platelet load dose treatment was 208.0 (72.0, 529.0) min, 259.0 (91.0, 340.0) min, and 125.0 (86.0, 170.0) min (P=0.044) in the three groups, respectively. Emergency percutaneous coronary artery intervention (PCI) start time was 60.9 (42.1, 95.8) hours, 61.3 (43.3, 92.2) hours, 30.5 (2.8, 44.1) hours (P<0.001) in the three groups, respectively. Among them, the moderate risk patients’ PCI starting time was 63.0 (48.1, 94.2) hours, 62.3 (42.1, 116.2) hours, and 40.1 (17.2, 60.4) hours (P>0.05), respectively. The high risk patients’ PCI starting time was 47.9 (23.7, 102.4) hours, 55.2 (44.0, 89.6) hours, 23.2 (1.7, 41.8) hours in the three groups, respectively (P<0.001). The hospitalization time of the patients was 7.0 (5.4, 9.4) days, 5.9 (4.9, 8.7) days, 4.7 (3.1, 6.2) days in the three groups (P<0.001), respectively. The hospitalization time of the moderate risk patients was 6.9 (4.9, 8.8) days, 6.4 (4.9, 8.0) days, 4.8 (3.2, 6.5) days in the three groups (P>0.05), respectively. The hospitalization time of the high risk patients was 7.1 (5.5, 9.9) days, 5.9 (4.6, 9.8) days, and 4.4 (3.0, 6.1) days, respectively (P<0.001). The fatality rate of inpatients was 4.9%, 0.0%, and 0.0%, respectively (P>0.05). The correlation coefficient of hospitalization time, diagnosis confirmed time and PCI starting time was 0.219 and 0.456 (P<0.05), respectively.ConclusionThe establishment and optimized process of chest pain center can accelerate the time of early diagnosis of NSTEMI, which is helpful to obtain stratified and graded standardized treatment for patients according to their conditions, to accelerate the specific treatment process of high risk NSTEMI patients, and shorten the hospitalization time.
ObjectiveTo introduce an innovative technique, the "balance-shaped sternal elevation device" and its application in the subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) for anterior mediastinal masses resection. MethodsPatients who underwent single-port thoracoscopic assisted anterior mediastinal tumor resection through the xiphoid process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from May to June 2024 were included, and their clinical data were analyzed. ResultsA total of 7 patients were included, with 3 males and 4 females, aged 28-72 years. The diameter of the tumor was 1.9-17.0 cm. The operation time was 62-308 min, intraoperative blood loss was 5-100 mL, postoperative chest drainage tube retention time was 0-9 days, pain score on the 7th day after surgery was 0-2 points, and postoperative hospital stay was 3-12 days. All patients underwent successful and complete resection of the masses and thymus, with favorable postoperative recovery. ConclusionThe "balance-shaped sternal elevation device" effectively expands the retrosternal space, providing surgeons with satisfactory surgical views and operating space. This technique significantly enhances the efficacy and safety of minimally invasive surgery for anterior mediastinal masses, reduces trauma and postoperative pain, and accelerates patient recovery, demonstrating important clinical significance and application value.
ObjectiveTo analyze prognostic ability of inflammation-based Glasgow prognostic score (GPS) in patients with ST-segment elevation myocardial infarction (STEMI).MethodsWe retrospectively analyzed the clinical data of 289 patients with STEMI admitted to the Department of Emergency in West China Hospital from April 2015 to January 2016. All study subjects were divided into three groups: a group of GPS 0 (190 patients including 150 males and 40 females aged 62.63±12.98 years), a group of GPS 1 (78 patients including 58 males and 20 females aged 66.57±15.25 years), and a group of GPS 2 (21 patients including 16 males and 5 females aged 70.95±9.58 years). Cox regression analysis was conducted to analyze the independent risk factors of predicting long-term mortality of patients with STEMI.ResultsThere was a statistical difference in long-term mortality (9.5% vs. 23.1% vs. 61.9%, P<0.001) and in-hospital mortality (3.7% vs. 7.7% vs. 23.8%, P<0.001) among the three groups. The Global Registry of Acute Coronary Events (GRACE) scores and Gensini scores increased in patients with higher GPS scores, and the differences were statistically different (P<0.001). Multivariable Cox regression analysis showed that the GPS was independently associated with STEMI long-term all-cause mortality (1 vs. 0, HR: 2.212, P=0.037; 2 vs. 0, HR: 8.286, P<0.001).ConclusionGPS score is helpful in predicting the long-term and in-hospital prognosis of STEMI patients, and thus may guide clinical precise intervention by early risk stratification.
Objective To investigate the efficacy of LDL-C lowering treatment on NSTE-ACS, and to analyze the target LDL-C level for clinical treatment. Methods PubMed, EMbase, the Cochrane Central Register of Controlled Trials, Web of Science databases were searched up to January 2016 for randomized controlled trials assessing the effects of LDL-C lowering therapy on major adverse cardiac events (MACE) in patients with NSTE-ACS. Two reviewers independently screened litertures, extracted data and assessed the risk of bias of included studies, and then meta-analysis was performed by using Stata12.0 and RevMan 5.3 software. Result A total of 12 RCT including 4 702 individuals with NATE-ACS were included. The results of meta-analysis showed that, compared with the control group, the statin group could significantly reduced the risk of MACE (RR=0.68, 95% CI 0.549 to 0.834,P=0.000). With 18.68 months of follow-up, patients in target LDL-C level from over 70 mg/dL to less than 100 mg/dL group had lower risk of MACE than other LDL-C level group. When LDL-C lower 20% to 40% than baseline with 28.99 months follow-up, patients in target of LDL-C level from over 70 mg/dL to less than 100 mg/dL group had lowest risk of MACE (RR=20.143, 95% CI 6.946 to 58.414,P=0.000). Conclusion LDL-C lower treatment can lower the risk of MACE in patients with NSTE-ACS. Patients in target LDL-C level from over 70 mg/dL to less than 100 mg/dL group have relatively low risk of MACE, in which patients who lower 20% to 40% LDL-C than baseline will get more benefits from LDL-C lowering therapy.
ObjectiveTo explore the effect of continuous improvement of quality control system on the emergency treatment efficiency for patients with acute ST segment elevation myocardial infarction (STEMI) after the establishment of Chest Pain Center. MethodsWe retrospectively analyzed the differences of theory examination scores acquired by the Chest Pain Center staff one month before and after they got the system training. Moreover, we designated the STEMI patients treated between May and August 2015 after the establishment of Chest Pain Center but before optimization of process to group A (n=70), and patients treated from September to December 2015 after optimization of process to group B (n=55). Then we analyzed the differences between these two groups in terms of the time from patients' arriving to registration, the time from arriving to first order, the length of stay in Emergency Department, and even the time from door to balloon (D2B). ResultsThe scores acquired by Chest Pain Center staff before and after system training were 69.89±6.34 and 87.09±4.39 respectively, with a significant difference (P＜0.05). All the time indicators of both group A and group B were shown as median and quartile. The time from patients' arriving to registration of group A and group B was 6.0 (0.0, 11.0) minutes and 1.0 (0.0, 3.0) minutes (P＜0.05); the time from arriving to first order was 12.8 (9.0, 18.0) minutes and 5.0 (3.0, 9.0) minutes (P＜0.05); the length of stay in Emergency Department was 54.0 (44.0,77.0) minutes and 33.0 (20.0, 61.0) minutes (P＜0.05); and the time of D2B was 107.5 (89.0, 130.0) minutes and 79.0 (63.0, 108.0) minutes (P＜0.05). ConclusionAfter taking measures such as drawing lessons from the past, training staff and optimizing process continuously, we have significantly shortened the acute STEMI patients' length of stay in the Emergency Department, which has saved more time for the following rescue of STEMI patients.
Objective To study the clinical and angiographic features in ST Segment Elevation Myocardial Infarction (STEMI) patients with spontaneous reperfusion. Methods A total of 519 patients with STEMI underwent Primary percutaneous coronary intervention (PCI) from January 2006 to December 2009 in Anzhen Hospital were enrolled. All patients were divided into the spontaneous reperfusion group (TIMI flow gradeⅢ ) and the non-spontaneous reperfusion group (TIMI flow grade 0-Ⅱ ) according to the TIMI flow grade before primary PCI. The incidence rate of spontaneous reperfusion through coronary angiography before primary PCI was observed, and the clinical relevant factors and angiographic lesion features of spontaneous reperfusion were analyzed. Results There were significant differences in age, CTnI peak value, high thrombus burden, and lesion location in distant LAD (P=0.000, 0.000, 0.002, 0.000, and 0.003, respectively) between the two groups. But there were no significant differences in gender, hypertension, diabetes mellitus, smoking history, hyperlipemia, angina pectoris history, culprit vessel distribution, lesion distribution in LCX and RCA, and collateral circulation between the two groups (Pgt;0.05 for all). Conclusion Compared to the patients without spontaneous reperfusion, patients with spontaneous reperfusion are younger in age, lower in CTnI peak value, and heavier in thrombosis burden, with culprit lesions mostly located in the distant LAD.
ObjectiveTo systematically review the effectiveness and safety of domestic tirofiban for Chinese population with non ST-elevation acute coronary syndromes (NSTE-ACS) in non-interventional therapy. MethodsWe searched databases including The Cochrane Library (Issue 11, 2013), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data from 1994 to 2014 to collect randomized controlled trials (RCTs) about domestic tirofiban for NSTE-ACS patients in non-interventional therapy. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Meta-analysis was then conducted using RevMan 5.2 software. ResultsA total of 23 RCTs were enrolled involving 2 425 patients. The results of meta-analysis showed that:a) the effectiveness of tirofiban in the trial group was significantly better than that in the control group (OR=3.62, 95%CI 2.33 to 5.63, P<0.000 01); b) ST segment down improvement in the trial group was better than that in the control group (WMD=0.39, 95%CI 0.30 to 0.49, P<0.000 01); c) improvement of platelet aggregation in the trial group was better than that in the control group (WMD=27.89, 95%CI 25.45 to 30.34, P<0.000 01); d) the incidences of cardiovascular events of composite endpoints in the trial group were lower than that in the control group (during 36 h:OR=0.20, 95%CI 0.12 to 0.31, P<0.000 01; and after 30 days:OR=0.31, 95%CI 0.23 to 0.42, P<0.000 01); and e) the incidence rate of bleeding in the trial group was higher than that in the control group (OR=1.53, 95%CI 1.09 to 2.15, P=0.02). ConclusionCompared with routine drugs used alone, tirofiban has better therapeutic effects in non-interventional therapy for Chinese population with NSTE-ACS, but the incidence of bleeding is relatively high.
Objective To investigate the correlation between plasma aminoterminal pro-B-type natriuretic peptide (NT-proBNP) level and severity of coronary artery lesions in patients with non-ST segment elevation myocardial infarction (NSTEMI). Methods NSTEMI patients presenting to the Emergency Department and Department of Cardiology from January 2013 to March 2017 were divided into four groups: thrombosis without stenosis, single vessel disease, double vessel diseases, and three vessel diseases. The general situation of the patients, the plasma NT-proBNP, troponin T, echocardiogram and coronary angiography results were analyzed. Results A total of 88 patients were included including 6 in thrombosis without stenosis group, 20 in single vessel disease group, 31 in double vessel diseases group, and 31 in three vessel diseases group. The NT-proBNP level, left ventricular ejection fraction, left ventricular end diastolic diameter, and coronary Gensini score in three vessel diseases group differed much from those in the other groups (P<0.05). The correlation of NT-proBNP with coronary Gensini score in all the patients was positve (t=0.663, P<0.05). Conclusion The level of plasma NT-proBNP in patients with NSTEMI is related to the severity of coronary artery disease.
With the adoption of the surgical principles emphasizing minimally invasive, precise, and individualized procedures, the sternum elevation via the subxiphoid approach for thoracoscopic surgery has become an important technique for the resection of anterior mediastinal masses. This method offers significant advantages in terms of increasing surgical field exposure, reducing surgical trauma, alleviating postoperative pain, and improving cosmetic outcomes. To establish a standardized surgical system and promote the consistent implementation of this technique, this consensus integrates the practical experiences of multiple thoracic surgery centers in China and relevant literature reports. It addresses core clinical issues such as surgical indications, preoperative assessment, anesthesia and intraoperative cooperation, key surgical techniques, postoperative management, prevention and treatment of complications, as well as training and quality control systems. The aim is to provide a safer and more effective minimally invasive solution for patients with anterior mediastinal masses and to facilitate the innovation of minimally invasive surgical modalities for the anterior mediastinum.
