RESUMEN
Objective:To investigate the effects of chest pain center construction in basic-level hospitals on treatment time and short-term prognosis in patients with acute ST-elevation myocardial infarction.Methods:A total of 162 patients with acute ST-elevation myocardial infarction who received percutaneous coronary intervention (PCI) in The First People's Hospital of Jiande between November 2014 and November 2018 were included in this study. Among them, 66 patients who received treatment in The First People's Hospital of Jiande between November 2014 and October 2016 were included in the control group. The remaining 96 patients who received treatment between November 2016 and November 2018 were included in the study group. The underlying diseases, PCI success rate, first medical contact-to-balloon time, door-to-balloon time, in-hospital mortality, incidence of heart failure on the next day of PCI, length of hospital stay, hospital medical cost were retrospectively analyzed.Results:There were no significant differences in underlying disease composition ratio and PCI success rate between the two groups (both P > 0.05). There were significant differences in first medical contact-to-balloon time [(185.2 ± 53.7) minutes vs. (108.6 ± 46.4) minutes, t = 6.128], door-to-balloon time [(121.5 ± 23.2) minutes vs. (68.7 ± 14.3) minutes, t = 7.341], length of hospital stay [(10.3 ± 3.5) days vs. (7.2 ± 2.8) days, t = 5.128], hospital medical cost [(43 582.0 ± 7 186.5) yuan vs. (35 479.0 ± 4 213.1) yuan, t = 8.361], in-hospital mortality [6.1% vs. 3.1%, χ2 = 4.784], the incidence of heart failure on the next day of PCI [13.6% vs. 4.2%, χ2 = 8.253] between the control and study groups (all P < 0.05). Conclusion:Establishment of a standardized chest pain center construction in basic-level hospital can greatly shorten the first medical contact-to-balloon time, door-to-balloon time and length of hospital stay, improve the cardiac function and prognosis of patients with myocardial infarction, and reduce medical cost.
RESUMEN
Objective To investigate the impact of the regional cooperative chest pain center (CPC) on therapeutic time and short term outcome after primary percutaneous coronary intervention (PCI) of patients with ST segment elevated myocardial infarction.Methods 372 patients with ST segment elevated myocardial infarction were enrolled in the study who had received were operated primary PCI 18 months before and after the regional cooperative CPC was set up.There were 156 patients in the green channel group before the setup of CPC and 216 patients in the CPC group.Total ischemia time,first medical contact (FMC) time,FML-to-balloon (FMC2B) time,door-to-balloon (D2B) time,hospital mortality rates,cardiac failure rates on the next day after PCI,length of CCU stays and hospital stays were compared between the two groups.Results Compared to the green channel group,total ischemia time[(281.0±102.7)min vs.(365.2±115.6)min,P＜0.05],FMC time [(174.3±97.5) min vs.(225.4±104.6) min,P＜0.05],FMC2B time [(106.7±61.2) min vs.(139.8±75.7) min,P＜0.05] and D2B time [(75.2±45.4) min vs.(102.4±53.7) min,P＜0.05] of the CPC group were significant shorter.The rates of reaching the standard of FMC2B time (70.83％ vs.34.62％,P＜0.001) and D2B time (75.93％ vs.40.38％,P＜0.001)were significantly higher in the CPC group.Cardiac failure rates on the next day after PCI was lower in the CPC group (14.35％ vs.23.72％,P=0.021),and CCU stays was shorter [(64.3±13.72)h vs.(92.6±15.65)h,P=0.043].Conclusions Establishment of a standardized regional cooperative CPC requires combination and consideration of the characteristics of local resources FMC2B time and D2B time of STEMI patients can be shorten by a standardized CPC lending to further shortening of total ischemia time and improvement in cardiac function.

With high incidence, high mortality, high disability and high medical cost, acute myocardial infarction (AMI), the most acute events of coronary heart disease (or the acute exacerbation of chronic coronary disease), becomes the priority in preventing and treating cardiovascular diseases and the vital point of reducing cardiovascular mortality. In recent years, with the continuous improvement of AMI treatment strategy and the application of new treatment methods, based on the recent large-scale clinical trials, the guideline of treating AMI are constantly updated at home and abroad to better guide clinical work. In this paper, we share the advanced technologies and concepts in treating AMI, and look forward to the new academic frontiers. We aim to make a brief analysis of the latest treatment guidelines and the latest research progress.
RESUMEN
Objective To explore the effect of regional synergistic treatment system on the treatment time and short-term prognosis of patients with ST-segment elevation myocardial infarction (STEMI).Methods A retrospective analysis of the clinical data of STEMI patients who admitted to emergency center of Suzhou Kowloon Hospital Affiliated to Shanghai Jiaotong University School of Medicine and underwent primary percutaneous coronary intervention (PPCI) from January 2013 to January 2017 were conducted. All patients were divided into two groups, group A was the patients who underwent the PPCI before the establishment of the acute chest pain area co-treatment system (from January 2013 to December 2014), and group B was the patients who received the treatment after the establishment of the area co-treatment system (from January 2015 to January 2017). The length of time from onset of symptoms to the balloon dilatation (S2B), the length of time from the first medical contact to the balloon dilatation (FMC2B), the length of time from entering the gate of hospital to the balloon dilatation (D2B), and the incidence of 90-day end point events (including heart failure, all-cause death, and other related adverse events) were collected. The relations of the establishment of the acute chest pain area co-treatment system and the incidence of 90-day end point events were analyzed by multivariable Logistic regression analysis.Results Among the 221 enrolled patients with STEMI, 83 patients were in group A and 138 patients were in group B respectively. Compared with group A, S2B time [minutes: 180 (140, 210) vs. 201 (154, 225)], FMC2B time [minutes: 89 (78, 100) vs. 94 (83, 107)] and D2B time [minutes: 66 (62, 70) vs. 85 (72, 99)] were significantly shortened in group B (allP < 0.05), the incidence of 90-day end point events were significantly decreased (heart failure:20.3％ vs. 32.5％, all-cause death: 1.4％ vs. 7.2％, other related adverse events: 23.2％ vs. 36.1％, allP < 0.05). It was shown by multivariable Logistic regression analysis that the establishment of the acute chest pain area co-treatment system could lower the incidence of 90-day end point events [heart failure: odds ratio (OR) = 1.904, 95％ confidence interval (95％CI) = 0.968-1.004, P = 0.048; all-cause death:OR = 11.724, 95％CI = 0.955-1.048,P = 0.013; other related adverse events:OR = 1.925, 95％CI = 1.049-3.530,P = 0.034].Conclusion The construction of regional synergistic treatment system can shorten the emergency treatment time of STEMI patients and reduce the incidence of 90-day end point events including heart failure and death.

RESUMEN
Objective To investigate the first medical contact to balloon ( FMC2B) time in our center and to identify the influencing factors .Methods This is a retrospective study conducted in the heart center of Beijing Luhe Hospital . A total of 140 patients undergoing primary percutaneous coronary intervention ( PCI) were enrolled between July 2013 to September 2014.Demographic data , clinical risk factors and the emergency process were evaluated .All the patients were categorized into 2 groups including:the conformed group ( patients with FMC2B<120 min for non-PCI-capable hospital and <90 min for direct arrival at Luhe hospital, n=59) and the unconformed group (n=81).Multivariant regression aralysis was done to analyse factors influencing FMC 2B time.Results Among the enrolled 140 patients, 58 patients were initially seen in a non-PCI-capable hospital , 31 patients were directly sent to Luhe hospital by ambulance and 51 patients arrived by themselves.The median FMC2B time was 106.16 min (interquartile range [ IQR ]: 77.37 -165.52 min ) and 42.1% ( 59/140 ) of the patients achieved the current recommended FMC2B time.In a multivariate logistic analysis , FMC to electrocardiographic ( ECG) within 10 min ( OR=5.61 , 95% CI 1.91-16.88 ) , admission during normal working hours ( OR=5.11 , 95%CI 1.88-13.85 ) , patient′s education level of high school or above ( OR=4.16 , 95%CI 1.53-11.34 ) , awareness of heart diseases ( OR =2.58, 95% CI 1.13 -5.91 ) were predictors of improving FMC2B. Transfer for primary PCI (OR=0.37, 95% CI 0.15-0.92) increased FMC2B.Conclusions Less than half of the patients with primary PCI achieved the goal of guidelines′recommended FMC2B time.Initial ECG, admission during normal working hours , patient′s education level and awareness of heart diseases and transfer for primary PCI are the independent predictors of FMC 2B time.
RESUMEN
@#BACKGROUND: Timely reperfusion in ST-segment elevation myocardial infarction (STEMI) improves outcomes. System delay is that between first medical contact and reperfusion therapy, comprising prehospital and hospital components. This study aimed to characterize prehospital system delay in Singapore. METHODS: A retrospective chart review was performed for 462 consecutive STEMI patients presenting to a tertiary hospital from December 2006 to April 2008. Patients with cardiac arrest secondarily presented were excluded. For those who received emergency medical services (EMS), ambulance records were reviewed. Time intervals in the hospital were collected prospectively. The patients were divided into two equal groups of high/low prehospital system delay using visual binning technique. RESULTS: Of 462 patients, 76 received EMS and 52 of the 76 patients were analyzed. The median system delay was 125.5 minutes and the median prehospital system delay was 33.5 minutes (interquartile range [IQR]=27.0, 42.0). Delay between call-received-by-ambulance and ambulance-dispatched was 2.48 minutes (IQR=1.47, 16.55); between ambulance-dispatch and arrival-at-patient-location was 8.07 minutes (IQR=1.30, 22.13); between arrival-at- and departure-from-patient-location was 13.12 minutes (IQR=3.12, 32.2); and between leaving-patient-location to ED-registration was 9.90 minutes (IQR=1.62, 32.92). Comparing patients with prehospital system delay of less than 35.5 minutes versus more showed that the median delay between ambulance-dispatch and arrival-at-patient-location was shorter (5.75 vs. 9.37 minutes, P<0.01). The median delay between arrival-at-patient-location and leaving-patient-location was also shorter (10.78 vs. 14.37 minutes, P<0.01). CONCLUSION: Prehospital system delay in our patients was suboptimal. This is the first attempt at characterizing prehospital system delay in Singapore and forms the basis for improving efficiency of STEMI care.
RESUMEN
Objective To evaluated the effect of the regional cooperative rescue model implemented on the length of time from first medical contact (FMC) to balloon dilation (B),economic expense and prognosis in patients with acute coronary syndrome (ACS).Methods Patients with ACS (including ST-segment elevation and non-ST-segment elevation) selected from other hospitals within 24 hours after onset were treated with emergency percutaneous coronary intervention.Patients were divided into two groups, regional cooperative rescue group and control group without the regional cooperative rescue model approved.The lengths of FMC-to-B time and Door-to-B time (from arrival at emergency department or OPD to balloon dilation),time required for patients referred to our hospital,cardiac function,averaged hospital costs,average hospital stay,percentage of medication used and a major adverse cardiac event (MACE) were analyzed.Results Mean FMC-to-B time,Door-to-B time,referral time and time consumed to obtain informed consent were significantly shorter [(106±33) min,(31 ±8) min,(62 ±18,8 ±3) min] vs.[(231 ±35) min,(109 ±26) min,(98 ±31) min,(28 ±11) min,respectively] by implementing the regional cooperative rescue compared with control group,and LVEF was increased,and LVED was deceased inregional cooperative rescue group.The mean costs [(44 123.0 ±3 427.0) yuan vs.(51 587.0 ±5 621.0)] yuan,days of hospital stay [(8.7 ±4.1) vs.(13.2 ±6.4)] and percentage of medication used were significantly decreased in the regional cooperative rescue group.The incidence of MACE inregional cooperative rescue group was 6.2％,whereas the incidence in control group was 16.8％.Conclusions The regional cooperative rescue model can improve the prognosis and decrease the FMC-to-B time,the rate of MACE and financial burden in patients with ACS.
RESUMEN
Objective To study the efficiency of tele-consultation on Internet with transmitting realtime 12-lead ECG carried out by the Chest Pain Center evaluated by the length of time required for the emergency percutaneous coronary intervention (PCI) in patients with ST segment elevation myocardial infarction (STEMI).Methods A total of 435 STEMI patients treated by emergency PCI were divided into the group A (n =98,admitted in 2010),group B (n =114,admitted in 2011) and group C (n =223,admitted in 2012).Data were collected before (2010) and after establishment of the Chest Pain Center (2011 to 2012) including the length of time elapsed from onset of symptoms to the first medical contact (FMC),the length of time required from FMC to the intra-aortic balloon inflated (FMC-2B) and the length of time required from entering the gate of hospital to the intra-aortic balloon inflated (D-2B).Measure data were described with non-normal median and interquartile intervals.Comparisons were made among groups with rank sum test.Results The median time of D2B of three groups were 107,78 and 59 mins in groups A,B and C,respectively.The differences in D2B among three groups were significant (P =0.000).The time of the D2B was shortened significantly because of the patients transferred to the hospital with a variety of ways (P =0.008).However,the length of D2B time was not significantly changed (P =0.846) when patients came to the hospital all on themselves.The median times from symptom onset to FMC in the group A,group B and group C were 112,62 and 78 mins.and the differences among three groups were not statistically significant (P =0.368).The median times of FMC2B in three groups were 287.0,313.5 and 421.8 mins,respectively,and there were no significant differences (P =0.135).Conclusions The establishment of the Chest Pain Center and Internet of things can effectively shorten the duration of D2B in STEMI patients.However,the reduction of time length from the symptom onset to reperfusion must rely on the coordination between communities and health care system.
