ObjectivesTo systematically review clinical values of multi-slice spiral computed tomography angiography (MSCTA) in diagnosis of chest pain triple (CPT).MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, CBM, VIP and WanFang Data databases were searched to collect diagnostic tests on CPT diagnosed by MSCTA from inception to October 2017. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was performed by Stata 12.0 software. The pooled weighted Sen, Spe, +LR, -LR, and the DOR were calculated, SROC and AUC were drawn.ResultsA total of 11 diagnostic studies were included. The results of meta-analysis showed that the pooled Sen, Spe, +LR, -LR, DOR and AUC of MSCTA for diagnosing CPT were 0.95 (95%CI 0.91 to 0.98), 0.97 (95%CI 0.94 to 0.98), 31.24 (95%CI 15.63 to 62.43), 0.05 (95%CI 0.02 to 0.10), 659.04 (95%CI 236.73 to 1 834.71) and 0.99 (95%CI 0.98 to 1.00), respectively.ConclusionsMSCTA has high sensibility and specificity for diagnosing CPT. Due to limited quantity and quality of the included studies, more high-quality studies are required to verify the above conclusion.
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.

Objective To explore the effect of first aid mode based on intelligent chest pain center on the rescue effect of patients with acute myocardial infarction (AMI). Methods AMI patients treated in the Second Hospital of Baoding between May 2020 and September 2023 were retrospectively selected. Patients who received traditional chest pain emergency mode between May 2020 and January 2022 were selected as the control group, and patients who received intelligent chest pain center model between February 2022 and September 2023 were selected as the study group. The first aid success rate, first aid time (first visit time, 120 arrival time, triage evaluation time, venous channel opening time, and electrocardiogram time), treatment timeliness [first medical contact to balloon time (FMC-to-B), door to balloon time (D-to-B), stent placement time, emergency stay time, and hospitalization time], basic vital signs (systolic blood pressure, heart rate, and respiratory rate), incidence of complications and family first aid satisfaction were compared between the two groups. Results A total of 98 patients were included, including 50 in the study group and 48 in the control group. There was no significant difference in the success rate of first aid between the study group and the control group (96.0% vs. 83.3%, P>0.05). The first visit time [(203.15±33.82) vs. (260.71±41.05) min], 120 arrival time [(10.45±1.61) vs. (14.02±2.31) min], triage evaluation time [(1.07±0.21) vs. (1.71±0.33) min], venous channel opening time [(1.31±0.16) vs. (2.95±0.42) min], electrocardiogram time [(5.52±1.08) vs. (6.89±1.38) min], FMC-to-B [(115.82±31.74) vs. (145.29±46.15) min], D-to-B [(78.15±30.41) vs. (112.53±34.12) min], stent placement time [(45.01±8.36) vs. (71.85±9.67) min], emergency stay time [(38.24±9.81) vs. (59.46±11.05) min] and hospitalization time [(12.98±1.27) vs. (15.31±1.80) d] were shorter in the study group than those in the control group (P<0.05). After first aid, the systolic blood pressure [(133.49±13.16) vs. (142.69±12.58) mm Hg (1 mm Hg=0.133 kPa)], heart rate [(90.26±18.25) vs. (103.69±17.49) beats per minute], respiratory rate [(22.15±2.87) vs. (24.87±3.08) breaths per minute] and complication rate (10.4% vs. 27.5%) in the study group were lower than those in the control group (P<0.05). The first aid satisfaction of family members was higher in the study group than that in the control group (97.9% vs. 82.5%, P<0.05). Conclusion The first aid model based on intelligent chest pain center can improve the success rate of first aid treatment for AMI patients, shorten the first aid treatment time, enhance the time effectiveness of treatment, stabilize the basic vital signs of patients, reduce the incidence of complications, and improve the satisfaction of family members with first aid treatment.
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.
