RESUMO
Objective:To explore the selection of strategies for early reperfusion therapy and its impact on prognosis in patients with acute ST segment elevation myocardial infarction (STEMI).Methods:The treatment data and 3-year follow-up results of acute myocardial infarction (AMI) patients in 49 hospitals in Hebei Province from January to December 2016 were collected. Patients with STEMI who received either intravenous thrombolytic therapy (ITT) or primary percutaneous coronary intervention (PPCI) within 12 hours of onset were enrolled. Baseline data, the time from the first diagnosis to the start of reperfusion (FMC2N for ITT patients and FMC2B for PPCI patients), vascular recanalization rate, in-hospital mortality, 1-year mortality, and 3-year mortality were compared between ITT and PPCI groups. The efficacy and prognosis of ITT and PPCI at different starting time of reperfusion (FMC2N≤30 minutes, FMC2N > 30 minutes, FMC2B≤120 minutes, FMC2B > 120 minutes) were analyzed.Results:A total of 1 371 STEMI patients treated with ITT or PPCI were selected, including 300 patients in the ITT group and 1 071 patients in the PPCI group. 1 055 patients were actually followed up (205 patients in the ITT group and 850 patients in the PPCI group), with a rate of 79.4%. There were no significant differences in age, gender, and previous history between the two groups. The time from the first diagnosis to the start of reperfusion in the ITT group was shorter than that in the PPCI group [minutes: 63 (38, 95) vs. 95 (60, 150), U = -9.286, P = 0.000], but was significantly longer than the guideline standard. Compared with the ITT group, the vascular recanalization rate in the PPCI group was higher [95.5% (1 023/1 071) vs. 88.3% (265/300), P < 0.01], and in-hospital mortality was lower [2.1% (22/1 071) vs. 6.7% (20/300), P < 0.01], but there were no significant differences in the 1-year mortality and 3-year mortality [5.3% (45/850) vs. 4.4% (9/205), 9.5% (81/850) vs. 9.3% (19/205), both P > 0.05]. Between ITT group and PPCI group with different reperfusion starting time, the FMC2N > 30 minutes group had the lowest vascular recanalization rate and the highest in-hospital mortality. Pairwise comparison showed that the vascular recanalization rate of the FMC2B ≤ 120 minutes group and the FMC2B > 120 minutes group were significantly higher than those of the FMC2N > 30 minutes group [95.5% (654/685), 95.6% (369/386) vs. 88.0% (220/250), both P < 0.008], the in-hospital mortality was significantly lower than that of the FMC2N > 30 minutes group [2.0% (14/685), 2.1% (8/386) vs. 7.6% (19/250), both P < 0.008]. There was no significant difference in 1-year mortality (χ 2 = 2.507, P = 0.443) and 3-year mortality (χ 2 = 2.204, P = 0.522) among the four groups. Conclusions:For STEMI patients within 12 hours of onset, reperfusion therapy should be performed as soon as possible. PPCI showed higher infarct related artery opening rate and lower in-hospital mortality compared with ITT, and had no effect on 1-year and 3-year mortality.
RESUMO
Objective:To investigate the in-hospital diagnosis and treatment time for patients with acute ischemic stroke in Hebei Province.Methods:The data of in-hospital diagnosis and treatment of acute ischemic stroke in Hebei Province were collected and analyzed, and then compared with the NINDS recommended time. Methods The data of in-hospital diagnosis and treatment of acute ischemic stroke in Hebei Province were collected and analyzed, and then compared with the NINDS recommended time.Results:The median time in hospital diagnosis and treatment was significantly longer than the NINDS recommended time (104 min vs. 60 min, P<0.001). The median time from completing the cranial CT scan to getting the CT report differed significantly to the NINDS recommended time (30 min vs. 20 min, P<0.001). The median time from getting the CT report to obtaining treatment was 43 min, which was significantly longer than the NINDS recommended 15 min ( P<0.001). The median time of in-hospital diagnosis and treatment for emergency service system (EMS) patients was 101 min, which was shorter than that for non-EMS patients (104 min, P=0.01). The median time of in-hospital diagnosis and treatment in Tertiary Hospital was 105 min, which was significantly longer than that in Secondary Hospital 99 min, ( P<0.05). Conclusions:The in-hospital emergency treatment delay in Hebei Province was relatively serious for patients with acute ischemic stroke. The time between obtaining the head CT report to beginning thrombolytic therapy is the most important factor in hospital delay. EMS can shorten in-hospital delay for acute ischemic stroke. Compared with the tertiary hospital, the secondary hospital has shorter in-hospital delay time.
RESUMO
Objective:To evaluate the efficacy of hemoperfusion (HP) combined with continuous veno-venous hemofiltration (CVVH) on the treatment of acute paraquat (PQ) poisoning.Methods:Prospective randomized controlled trials and retrospective studies on the efficacy of HP combined CVVH in patients with oral PQ poisoning (poisoning time ≤ 24 hours) were found by searching from PubMed, Embase, Cochrane Library, Web of Science, SinoMed, CNKI and Wanfang databases before November 1st, 2019. The experimental group was treated with HP+CVVH, and the control group was treated with HP. Data included the general information of the literature, mortality, survival time, the incidence of respiratory failure and circulatory failure. The bias risk and the data were analyzed using the RevMan 5.3 software.Results:A total of 1 041 literatures were retrieved, and 7 literatures were finally enrolled, including 1 199 patients, with 735 patients in the control group and 464 patients in experimental group. Meta-analysis showed that compared with HP alone, HP+CVVH could significantly reduce the short-term mortality [4-day mortality: hazard ratio ( HR) = 0.52, 95% confidence interval (95% CI) was 0.38-0.71, P < 0.000 1], but no significant improvement in long-term mortality was found (28-day or 30-day mortality: HR = 0.68, 95% CI was 0.39-1.21, P = 0.19; 90-day mortality: HR = 1.13, 95% CI was 0.61-2.10, P = 0.07; total mortality: HR = 0.96, 95% CI was 0.72-1.29, P = 0.78). The survival time of patients treated with HP+CVVH was significantly longer than that of HP patients [mean difference ( MD) = 2.02, 95% CI was 0.81-3.22, P = 0.001], but the heterogeneity between studies was large. According to the type of literature, a subgroup analysis showed that the survival time of patients treated with HP+CVVH in prospective randomized controlled trials and retrospective studies were significantly longer than that of HP patients (prospective studies: MD = 1.53, 95% CI was 0.94-2.12, P < 0.000 01; retrospective studies: MD = 2.40, 95% CI was 0.08-4.73, P = 0.04). Compared with HP group, HP+CVVH could significantly reduce the incidence of circulatory failure [relative risk ( RR) = 0.40, 95% CI was 0.30-0.52, P < 0.000 01], but the incidence of respiratory failure significantly increased ( RR = 2.75, 95% CI was 2.18-3.48, P < 0.000 01). Conclusion:HP combined with CVVH can reduce the short-term mortality and the incidence of circulatory failure, prolong the survival time, and save time for further rescue, but it can't improve the long-term prognosis of patients.
RESUMO
Objective@#To investigate the application of emergency medical service (EMS) of Hebei Province and preliminarily analyze its value in the treatment of acute stroke patients.@*Methods@#We collected data of 4 147 acute stroke patients admitted to the Emergency Department between January 2016 and December 2016 in 49 hospitals of Hebei Province. Patients were divided into the EMS group and non-EMS group according to the pattern of arriving hospital. The general data, the onset-to-door time, door-to-treatment time, thrombolytic rate, length of hospital stay and prognosis were compared between the two groups. LSD-t test, Mann-Whitney U or Chi-squared test or Fisher exact test was used for statistical analysis as appropriate.@*Results@#A total of 4 147 acute stroke patients were enrolled, including 589 patients (14.2%) with hemorrhagic stroke and 3 558 patients (85.8%) with ischemic stroke. A total of 750 patients (18.1%) were admitted to the hospital by EMS. The proportion of patients with hemorrhagic stroke who used EMS was higher than that of ischemic stroke (33.4% vs 15.5%, P<0.01). The median onset-to-foor time in the EMS group was less than that in the non-EMS group (1.75 h vs 4.57 h, P<0.01). The median time of onset-to-door time within 1 h in the EMS group was longer than that of the non-EMS group (0.67 h vs 0.53 h, P<0.01). There was no significant difference between the two groups in 1-<2 h period and 2-<3 h period. The median time of onset-to-door time of ≥3 h in the EMS group was shorter than that of the non-EMS group (5.0 h vs 9.47 h, P<0.01). In the EMS group, the proportion of patients with onset-to-door time <3 h was higher than that of the non-EMS group (66.13% vs 57.44%, P<0.01). Compared with the non-EMS group, the time of door-to-treatment time was much shorter in the EMS group (87 min vs 101 min, P<0.01). The length of hospital stay in the EMS group was shorter than that of the non-EMS group [11 (7,14) days vs 12 (6,16) days, P<0.01]. In the EMS group, 15.9% patients received thrombolytic therapy, whereas only 11.0% patients in the non-EMS group received this therapy (P=0.001). In the EMS group, 88.8% patients achieved more favorable outcomes at discharge, which was higher than that in the non-EMS group (85.5%, P=0.02).@*Conclusions@#EMS is considered as effective in shortening onset-to-door time, reducing door-to-treatment time, improving thrombolytic rate, reducing hospitalization days, and enhancing the prognosis of acute stroke patients.
