Abstract Aim Current guidelines recommend that patients with ST-elevation myocardial infarction (STEMI) receive primary percutaneous coronary intervention (PCI) with a door-to-balloon (D2B) time of 90 minutes. This time frame has been difficult to achieve in developing countries. We aimed to test the hypothesis that using WhatsApp for inter-hospital transfer in STEMI primary PCI would result in shorter D2B time through avoiding emergency department (ED) waiting. Methods In the period from May 2018 to April 2019, 300 patients with STEMI treated with primary PCI were prospectively enrolled in a multi-center observational study covering 3 PCI-capable centers in our city. Patients were categorized into 3 groups: G-1; Self-presenting to the ED, G-2; Transferred by ambulance to the ED and G-3; those transferred from non-PCI capable centers directly to catheterization laboratory (bypassing the ED as possible) after the team was pre-activated through an ECG image sent using WhatsApp. The primary endpoint was between-groups difference in total ischemic and D2B times. Results All groups were matched regarding baseline criteria. WhatsApp use was associated with significantly shorter D2B time (166.5±33.8 vs 157.8±29.6 vs 120.8±35.2 minutes in groups 1, 2 and 3 respectively, P<0.001) and shorter total ischemic time (258.9±33.9 vs 249.6±29.4 vs 212.7±35.4 minutes in groups 1, 2 and 3 respectively, P<0.001). Linear regression showed that WhatsApp referral significantly reduces ED waiting time by about 20.4 minutes (95% CI −21.6 to −19.3 minutes, P<0.001). Conclusion Using WhatsApp for inter-hospital transfer in primary PCI is associated with significantly shorter D2B times.

AbstractThere is concern whether patients with ST-segment elevation myocardial infarction (STEMI) who admitted to a percutaneous coronary intervention (PCI) center from interhospital transfer is associated with longer reperfusion time compared with direct admission. We evaluated the reperfusion delays in patients with STEMI who admitted to a primary PCI center through interhospital transfer or direct admission. We retrospectively analyzed 6,494 consecutive STEMI patients admitted between 2011 and 2019. Compared with direct admission (n = 4,121; 63%), interhospital transferred patients (n = 2,373) were younger (55 ± 10 vs. 56 ± 10 years, p < 0.001), had similar gender (85.6 vs. 86% male, p = 0.67), greater proportion of off-hour admission (65.2 vs. 48.3%, p < 0.001), less diabetes mellitus (28 vs. 30.8%, p = 0.019), and received more primary PCI (70.5 vs. 48.7%, p < 0.001). Interhospital transferred patients who received primary PCI (n = 3,677) or fibrinolytic (n = 238) had longer symptom-to-PCI center admission time (median, 360 vs. 300 minutes, p < 0.001), shorter door-to-device (DTD) time for primary PCI (median, 74 vs. 87 minutes, p < 0.001), and longer total ischemic time (median, 465 vs. 414 minutes, p < 0.001). Logistic regression in interhospital transferred patients showed that delay in door-in-to-door-out (DI-DO) time at the first hospital was strongly associated with prolonged total ischemic time (adjusted odds ratio = 3.92; 95% confidence interval: 3.06–5.04, p < 0.001). This study suggests that although interhospital transferred patients received more primary PCI with shorter DTD time, interhospital transfer creates longer total ischemic time that associates with the delay in DI-DO time at the first hospital that should be improved.

BACKGROUND We wanted to assess the clinical profile and in-hospital outcomes of Primary Percutaneous Coronary Intervention (PPCI) for ST-segment Elevation Myocardial Infarction (STEMI) in India in ESI (Employee Scheme Insurance) beneficiaries. METHODS From January 2017 to July 2018, 122 consecutive acute STEMI patients undergoing PPCI under ESI scheme were included in the study. Patients’ clinical profile, detailed procedural characteristics, time variables along with in-hospital major adverse cardiovascular events (MACE) were also assessed. RESULTS 122 patients underwent primary PCI during the study period. In the study, mean age was 55.23 (27 - 85) years; 94 (77.04 %) were males; 53 (43.44 %) were hypertensives; 38 (31.14 %) were smokers; and 44 (36.06 %) were diabetics. Ten (8.19 %) patients were in cardiogenic shock (CS). Anterior myocardial infarction was present in 70 (57.37 %) patients. The median chest-pain-onset to hospitalarrival-time was 270 (70 - 720), door-to-balloon time was 55 (20 - 180) and total ischemic time was 325 (105 - 780) minutes. In-hospital adverse events occurred in 14 (11.4 %) patients [death 8 (6.55 %), major bleeding 2 (1.63 %), urgent CABG 3 (2.45 %) and stroke 1 (0.81 %)]. Seven patients with cardiogenic shock died. CONCLUSIONS The mean age of our cohort was 55.23 years. In our study, majority of patients were males (77.05 %), hypertension was associated with 43.44 %, and diabetes was associated with 36.06 % of patients. Procedural success was achieved in 95.89 %. The overall in-hospital mortality was 6.55 % and 70 % in the cardiogenic shock subset. KEYWORDS Primary PCI, STEMI, ESI, PCI

ObjectiveThe Third Danish Study of Optimal Acute Treatment of Patients with ST-segment Elevation Myocardial Infarction – Ischaemic Postconditioning (DANAMI-3-iPOST) did not show improved clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI) treated with ischaemic postconditioning. However, the use of thrombectomy was frequent and thrombectomy may in itself diminish the effect of ischaemic postconditioning. We evaluated the effect of ischaemic postconditioning in patients included in DANAMI-3-iPOST stratified by the use of thrombectomy.MethodsPatients with STEMI were randomised to conventional primary percutaneous coronary intervention (PCI) or ischaemic postconditioning plus primary PCI. The primary endpoint was a combination of all-cause mortality and hospitalisation for heart failure.ResultsFrom March 2011 until February 2014, 1234 patients were included with a median follow-up period of 35 (interquartile range 28 to 42) months. There was a significant interaction between ischaemic postconditioning and thrombectomy on the primary endpoint (p=0.004). In patients not treated with thrombectomy (n=520), the primary endpoint occurred in 33 patients (10%) who underwent ischaemic postconditioning (n=326) and in 35 patients (18%) who underwent conventional treatment (n=194) (adjusted hazard ratio (HR) 0.55 (95%confidence interval (CI) 0.34 to 0.89), p=0.016). In patients treated with thrombectomy (n=714), there was no significant difference between patients treated with ischaemic postconditioning (n=291) and conventional PCI (n=423) on the primary endpoint (adjusted HR 1.18 (95% CI 0.62 to 2.28), p=0.62).ConclusionsIn this post-hoc study of DANAMI-3-iPOST, ischaemic postconditioning, in addition to primary PCI, was associated with reduced risk of all-cause mortality and hospitalisation for heart failure in patients with STEMI not treated with thrombectomy.Trial registration numberNCT01435408.

Summary Background The China ST-segment elevation myocardial infarction (STEMI) Care Project (CSCAP) was launched in 2011 to address the problems of insufficient reperfusion and long treatment delay in STEMI care in China. Aim To describe the baseline status of STEMI emergency care in Tertiary PCI Hospitals using Phase 1 (CSCAP-1) data. Design CSCAP-1 is a prospective multi-center STEMI registry. Methods and results A total of 4191 patients with symptom onset within 12 or 12–36 h requiring primary percutaneous coronary intervention (PCI), were enrolled from 53 tertiary PCI hospitals in 14 provinces, municipalities, and autonomous regions of China in CSCAP-1. Among them, 49.0% were self-transported to the hospital, 26.5% were transferred to the hospital by calling the emergency medical services directly, and 24.5% were transferred from other hospitals. In patients with symptom onset within 12 h, 83.2% received primary PCI, 5.9% received thrombolysis and 10.9% received conservative medications. The median door-to-balloon time was 115 (85–170) min and the median door-to-needle time for in-hospital thrombolysis was 80 (50–135) min. The overall in-hospital all-cause mortality was 2.4%, while it was 5.3% in the non-reperfusion group and 2.1% in the reperfusion group (P &lt; 0.001). Conclusion Although a long treatment delay and a high proportion of patients transporting themselves to the hospital were observed, trends were positive with greater adoption of primary PCI and lower in-hospital mortality in tertiary hospitals in China. Our results provided important information for further integrated STEMI network construction in China.

Background and aims: In patients with ST-segment elevation myocardial infarction (STEMI), mortality is directly related to time to reperfusion with guidelines recommending patients be delivered directly to centres for primary percutaneous coronary intervention (PCI). The aim of this study was to describe the impact of inter-hospital transfer on reperfusion time and to assess whether or not treatment delays influenced clinical outcomes in comparison with direct admission to a primary PCI centre in a large regional network. Method and results: We undertook an observational cohort study of patients with STEMI treated with primary PCI between 2005 and 2015 in London, UK. Patient details were recorded at the time of the procedure in databases using the British Cardiovascular Intervention Society PCI dataset. The primary end-point was all-cause mortality at a median of 4.1 years (interquartile range: 2.2–5.8 years). Secondary outcomes were in-hospital major adverse cardiac events. Of 25,315 patients, 17,560 (69.4%) were admitted directly to a primary PCI centre and 7755 (31.6%) were transferred from a non-primary PCI centre. Patients in the direct admission group were older and more likely to have left ventricular impairment compared with the inter-hospital transfer group. Median time from call for help to reperfusion in transferred patients was 52 minutes longer compared with patients admitted directly ( p <0.001). However, call to first hospital admission was similar. Kaplan–Meier analysis demonstrated significantly lower mortality rates in patients who were transferred directed to a primary PCI centre compared with patients who were transferred from a non-PCI centre (17.4% direct vs. 18.7% transfer, p=0.017). Furthermore, after propensity matching, direct admission for primary PCI was still a predictor of all-cause mortality (hazard ratio: 0.89, 95% confidence interval: 0.64–0.95). Conclusions: In this large registry of over 25,000 STEMI patients treated by primary PCI survival was better in patients admitted directly to a cardiac centre versus patients transferred for primary PCI, most likely due to longer call to balloon times in patient transferred from other hospitals.

Objective: ST-segment elevation myocardial infarction (STEMI) patients with the multivessel disease have distinctive plaque characteristics in non-IRA lesions. Intensive statin therapy was a potential approach to treat STEMI patients with the non-IRA disease. However, there is still poor evidence about the therapeutic effect. In this study, we have evaluated the detailed therapeutic effect of statin plus ezetimibe intensive therapy. Method: For STEMI patients with non-IRA disease undergoing primary percutaneous coronary intervention (PCI), 183 control STEMI patients without non-IRA disease undergoing primary PCI, and 200 STEMI patients with non-IRA disease undergoing primary PCI were introduced into this study. 200 STEMI patients with non-IRA disease undergoing primary PCI were divided into Normal group, Intensive group, Normal & Combined group, and Intensive & Combined group. The baseline information for each participant was recorded. Meanwhile, the physiological and biochemical indicators of each member with different treatments were collected after one-year follow-up. Result: For STEMI patients with non-IRA disease undergoing primary PCI, no differences could be detected in multiple indexes such as OCT examination results, age, stroke, etc. However, diabetes mellitus, smoking, and coronary Gensini score were different between different groups (P<0.05). After one year follow-up, cholesterol, low-density lipoprotein, coronary Gensini score, thin-cap fibroatheroma, length of non-infarcted arterial lesions, non-infarct artery lesion range, myocardial infarction again, and revascularization again were significantly different between different groups (P<0.05). Conclusion: The results mentioned above suggested that pitavastatin combined with ezetimibe was an effective approach to STEMI patients with non-IRA disease undergoing primary PCI. The results obtained in this study have provided a novel way for the treatment of STEMI patients with non-IRA disease undergoing primary PCI.

Background: Elevated neutrophil to leukocyte ratio in patients with ST-segment elevation myocardial infarction (STEMI) is associated with adverse clinical outcomes. However, whether decreased eosinophil ratio after primary percutaneous coronary intervention (PCI) reflects larger infarct size has not been fully investigated. This study examined the relationship between eosinophil ratio and creatinine kinase-MB (CK-MB) elevation after primary PCI in patients presenting with STEMI. Methods and Results: We analyzed the data of 321 consecutive patients who underwent primary PCI for ST-elevation myocardial infarction between January 2009 and August 2015. Total and each type of leukocyte counts 24 hours after admission were measured. The eosinophil/leukocyte ratio (ER) was calculated as the ratio of eosinophil to leukocyte count. The primary end point was major adverse cardiac event (MACE) and the follow-up period was 180 days. The mean ER and max CK-MB was 0.44±0.65 % and 217.3±224.4 IU/l, respectively. ER obtained 24 hours after admission was inversely correlated with CK-MB concentration (r=-0.37, r2=0.14, P<0.001). MACE within 180 days occurred in 68 patients (21%) including death (9%), myocardial infarction (MI) (1%) and target lesion or vessel revascularization (10%). Patients who had MACE within 180 days had lower ER (0.20±0.51 vs 0.49±0.66, P<0.001) at 24 hours after admission. Conclusions: The decreased ER after primary PCI in patients presenting with STEMI was associated with increased CK-MB concentration, which might indicate larger infarct size, therefore, poor prognosis.

Abstract Background Long-term reports on reperfusion therapy for acute ST-segment elevation myocardial infarction (STEMI) in developing countries are scarce. Purpose We reported changes in acute reperfusion therapy for STEMI that have been observed over time in an academic tertiary care percutaneous coronary intervention (PCI) centre that hosting a STEMI network in the large metropolitan area of Jakarta, Indonesia since 2010 and covering around 11 million inhabitants. Methods A retrospective analysis was performed in 6336 patients with STEMI who admitted to the emergency department of a PCI centre in 2008 (before STEMI network introduction), and during 2011 to 2018. Results Among STEMI patients admitted during 2011–2018 (mean age: 56±10 years, 86% male), 57.6% had anterior wall myocardial infarction, and 71.3% presented with Killip classification I. Compared with the period 2011–2014 (N=2766), patients who were admitted in the period 2015–2018 (N=3250) were receiving more primary percutaneous coronary intervention (PCI) (61.6% vs. 44.2%, P&lt;0.001) with shorter door-to-device time (median 72 min versus 97 min, P&lt;0.001), and less in-hospital fibrinolytic therapy (2.7% vs. 4.8%, P&lt;0.001). The percentage of STEMI patients who did not receive reperfusion treatment decreased from 51% to 35.5% (P&lt;0.001). In-hospital mortality declined from 10% in 2008 (before the STEMI network was initiated) and 8% in 2011 to 6.4% in 2018 (P for trends = 0.05). Multivariable analysis showed that primary PCI was significantly associated with better in-hospital survival (adjusted odds ratio, 0.52; 95% confidence interval, 0.42 to 0.65, P&lt;0.001). Conclusion The data indicate that the introduction of a STEMI network resulted in more patients receiving timely primary PCI and lower early mortality rates in recent years.

Objective We aimed to determine whether the prognostic value of the shock index (SI) and its derivatives is better than that of the Thrombolysis In Myocardial Infarction risk index (TRI) for predicting adverse outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods A total of 257 patients with STEMI undergoing primary PCI from January 2018 to June 2019 were analyzed in a retrospective cohort study. The SI, modified shock index (MSI), age SI (age × the SI), age MSI (age × the MSI), and TRI at admission were calculated. Clinical endpoints were in-hospital complications, including all-cause mortality, acute heart failure, cardiac shock, mechanical complications, re-infarction, and life-threatening arrhythmia. Results Multivariate analyses showed that a high SI, MSI, age SI, age MSI, and TRI at admission were associated with a significantly higher rate of in-hospital complications. The predictive value of the age SI and age MSI was comparable with that of the TRI (area under the receiver operating characteristic curve: z = 1.313 and z = 0.882, respectively) for predicting in-hospital complications. Conclusions The age SI and age MSI appear to be similar to the TRI for predicting in-hospital complications in patients with STEMI undergoing primary PCI.
