Distribution of catheterisation laboratories in Indonesia 2017-2022: a nationwide survey.

Background: Geographical terrains of Indonesia pose a major hindrance to transportation. The difficulty of transportation affects the provision of acute time-dependent therapy such as percutaneous coronary intervention (PCI). Also, Indonesia's aging population would have a significant impact on the prevalence of acute coronary syndrome in the next decade. Therefore, the analysis and enhancement of cardiovascular care are crucial. The catheterisation laboratory performs PCI procedures. In the current study, we mapped the number and distribution of catheterisation laboratories in Indonesia. Methods: A direct survey was used to collect data related to catheterisation laboratory locations in July 2022. The population data was sourced from the Ministry of Home Affairs. The recent growth of catheterisation laboratories was examined and evaluated based on geographical areas. The main instruments for comparing regions and changes throughout time are the ratio of catheterisation laboratories per 100,000 population and the Gini index (a measure of economic and healthcare inequality. Gini index ranges from 0 to 1, with greater values indicating more significant levels of inequality). Regression analysis was carried out to see how the number of catheterisation laboratories was affected by health demand (prevalence) and economic capacity (Gross Domestic Regional Product [GDRP] per Capita). Findings: The number of catheterisation laboratories in Indonesia significantly increased from 181 to 310 during 2017-2022, with 44 of the 119 new labs built in an area that did not have one. Java has the most catheterisation laboratories (208, 67%). The catheterisation laboratory ratio in the provinces of Indonesia ranges from 0.0 in West Papua and Maluku to 4.46 in Jakarta; the median is 1.09 (IQR 0.71-1.18). The distribution remains a problem, as shown by the high catheterisation laboratory Gini index (0.48). Regression shows that distribution of catheterisation laboratories was significantly affected by GDRP and the prevalence of heart disease. Interpretation: The number of catheterisation laboratories in Indonesia has increased significantly recently, however, maldistribution remains a concern. To improve Indonesia's cardiovascular emergency services, future development of catheterisation laboratories must be better planned considering the facility's accessibility and density.

Acute Limb Ischemia after Cardiovascular Surgery: A Deadly Duo Combination with High Mortality.

Acute limb ischemia (ALI) is a predictor of high morbidity and mortality. Previous studies showed that ALI developed after cardiac surgery may increase mortality. This study aimed to elucidate the clinical course and identify risk factors contributing to mortality in patients with ALI after cardiovascular surgery. This is a single-center retrospective cohort study. We analyzed data from 52 patients with ALI after cardiovascular surgery between 2016 and 2020. We evaluated the risk factors for 1-year mortality using Cox proportional hazards regression analysis. Most of the patients with ALI were male and the median age was 56 years (23-72 years). Most of the patients with ALI had coronary artery diseases. The 1-year mortality rate was 55.8% ( n = 29 patients). Multivariable analysis revealed that cardiopulmonary bypass (CPB) time ≥ 100 minutes (hazard ratio [HR]: 3.067, 95% confidence interval [CI]: 1.158-8.120) and postoperative acute kidney injury (HR: 2.927, 95% CI: 1.358-6.305) were significantly increasing the risk of mortality in patients with ALI after an operation. ALI after cardiovascular surgery was associated with high 1-year mortality in our study and long CPB time and postoperative acute kidney injury contributed to the mortality.

Interhospital Transfer versus Direct Admission in Patients with Acute ST-Segment Elevation Myocardial Infarction.

There 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.

5-Year Follow-Up of Endovascular Management in a Patient with Chronic Concomitant DeBakey Type II and IIIa Aortic Dissection.

The incidence of chronic concomitant DeBakey Type II and IIIa aortic dissection is uncommon and complex. Since the mortality rate is very high, it requires a precise and holistic treatment plan. In some cases, when the patients refuse to undergo open surgery or the patients' condition is not suitable for open surgery, thoracic endovascular aortic repair (TEVAR) is the recommended therapeutic approach. In this case, a patient refused to undergo open surgery and chose TEVAR instead. The patient survived the procedure and lived for years. We present the case of a successful TEVAR procedure in a patient with chronic concomitant DeBakey Type II and IIIa aortic dissection in a 51-year-old man and the 5-year postoperative follow-up of the patient's condition.

Case Report: Successful results of direct varicose vein ablation with EVLA in chronic venous insufficiency patient in Indonesia.

Background: Varicose veins are considered a chronic venous disease. Delaying treatment might cause several late complications that contribute to a high burden on healthcare systems. It may be treated with endovenous laser ablation (EVLA) and stab avulsion as additional procedures. Varicose direct ablation has been promoted to replace stab avulsion in certain conditions. Here we report the case of a 71-year-old female who presented with chronic venous insufficiency managed by an endovascular therapeutic approach using direct varix ablation for the first time in National Cardiovascular Center - Harapan Kita, Jakarta, Indonesia. Case report: A 71-year-old female came to the outpatient clinic with a large bulging vein in her leg. Duplex ultrasound showed that the great saphenous vein (GSV) was incompetent with a varicose vein in the medial part of proximal GSV below the knee. The patient underwent EVLA with direct varicose ablation using Utoh's technique. Duplex sonography evaluation showed the right GSV was utterly obliterated, including the varicose vein. The patient was discharged two days after the procedure without significant complaints nor pain medication. Conclusions: Direct varicose ablation was proposed as a better alternative than stab avulsion. The varicose vein can be managed with EVLA without a scalpel, incision, avulsion, or phlebectomy. In this case presentation, the endovascular therapeutical approach with Utoh's ablation technique showed promising results, and no complication was found in the patient.

Endovascular management of aortic aneurysm with severe neck angulation and/or iliac artery tortuosity using multiple stiff wire technique: a case series.

Background: Suitable aortic neck is one of the essential components for thoracic endovascular aortic repair (TEVAR) and endovascular aortic repair (EVAR). Advanced techniques were developed to adjust and compromise the aneurysm neck angulation but with adding additional devices and complexity to the procedure. We proposed a simple technique to modify severe neck angulation and/or iliac artery tortuosity by using the multiple stiff wire (MSW) technique. Method: Two femoral accesses were required for the MSW technique. A guidewire with a support catheter was inserted through the right and left femoral arteries and positioned in the abdominal or thoracic aorta. Wire exchanges were done with extra stiff wire in both femoral accesses. It can be considered to add multiple stiff wires to align the torturous neck / iliac artery. Delivery of the stent graft main body can be done via one of the accesses. Result: Six patients with different aortic pathology were admitted to our hospital. Four patients undergo EVAR procedure and two patients undergo TEVAR procedure. All patients had aortic neck angulation problems with one patient having iliac artery tortuosity. MSW technique was performed on the patients with good results. Follow-up CTA after 3 months revealed a good stent position without stent migration and no endoleak was found in all but one patient. Conclusion: MSW technique is a simple and effective technique to modify aortic neck/iliac artery angulation in TEVAR or EVAR procedure.

Acute Embolic Occlusion of Renal Artery after the Bentall Procedure: the Role of Primary Renal Angioplasty.

Acute renal occlusion is an uncommon emergency problem in daily practice. The diagnosis is often missed or delayed not only because of its rarity but also nonspecific of clinical presentation. Sudden and complete termination of arterial blood supply to the kidney may lead to renal infarction and a complete loss of renal function. Although the need of early revascularization is uniformly recommended, but the methods has not been established. We presented a case of acute thromboembolic renal artery occlusion in patient who had a history of Bentall's surgery. Renal infarction and artery occlusion were clearly visualized by computed tomography angiogram (CTA). The patient was successfully treated with angioplasty and stenting of main renal artery with complete disappearance of symptoms and recovery of his renal function.

Late presentation of middle aortic syndrome complicated with severe aortic regurgitation; the role of endovascular intervention as a bridging for Bentall surgery.

Middle aortic syndrome presents with segment narrowing of the descending thoracic and abdominal aorta. A common manifestation is uncontrolled hypertension, which can lead to severe aortic regurgitation in the long term. We have presented the case of a 31-year-old woman with worsening heart failure symptoms and longstanding uncontrolled hypertension. Echocardiography revealed severe aortic regurgitation. Aortic computed tomography showed severe stenosis of the aorta at the diaphragm level. Stent graft implantation was performed, followed by Bentall surgery 1 year later. Endovascular stent graft implantation of the descending aorta can be used safely as a bridging surgery for the Bentall procedure to reduce the patient's blood pressure and relieve heart failure symptoms.

Looping wire technique to facilitate true lumen wiring during TEVAR in type B aortic dissection with aneurysmal degeneration: A case report.

INTRODUCTION AND IMPORTANCE: Wiring true lumen during Thoracic Endovascular Aortic Repair (TEVAR) is sometimes difficult in complicated Type B Aortic Dissection (TBAD). CASE PRESENTATION: We treated a TBAD patient with large false lumen, compressed true lumen and multiple entries. After repeated wire misdirection to false lumen, we tried a new technique in which the wire in the false lumen was looped after entrance to true lumen and pushed distally. The looped wire was then used as guide to advance a second wire to the ascending aorta. TEVAR could then be completed with good result. DISCUSSION: Wiring the true lumen might be one of the most challenging steps during TEVAR in complicated TBAD. Several methods have been used to overcome the problems, but the cost and availability might be a problem in some countries. The looping wire technique may serve as an alternative method of guiding the process of wiring the true lumen during complicated TEVAR. CONCLUSION: Looping wire technique can be used as an alternative method to facilitate true lumen wiring during TEVAR.

Indonesian medical frontliners during the coronavirus disease 2019 pandemic: Have we been protecting them enough?

BACKGROUND AND AIM: The coronavirus disease 2019 pandemic has brought deteriorating physical and mental burdens to health care workers (HCWs) in Indonesia, mainly attributed to the lack of protection and screening among HCWs, patients' concealment of their travel and medical history, and perceived social stigma and discrimination. Hence, we deliver our perspectives and recommendations based on the current situation in Indonesia to enforce their safeties. We encourage stakeholders to implement a systematic approach by employing stringent prevention strategies, ensuring adequate personal protective equipment (PPE) provision and equitable PPE distribution, and routine HCWs screening to prevent nosocomial clusters, in addition to the provision of psychosocial support to HCWs by offering social aids and psychological sessions. Furthermore, social stigma and discrimination toward HCWs and patients should also be addressed and mitigated, thus preventing concealments of patients' history and alleviating emotional burdens. We believe that providing continuous support to HCWs would lead to key benefits in ensuring a winning battle against the COVID-19 pandemic. RELEVANCE FOR PATIENTS: HCWs are pivotal players in winning the battle against the COVID- 19 pandemic. Ensuring their safety and well-being will enable them to deliver better healthcare services, thus resulting in mutual benefit for themselves, the patients, and the nation's recovery.

Performance of Primary Angioplasty for STEMI during the COVID-19 Outbreak.

There has been concern whether the declining cases of ST-segment elevation myocardial infarction (STEMI) during the coronavirus disease 2019 (COVID-19) outbreak associate with primary angioplasty performance. We assessed the performance of primary angioplasty in a tertiary care hospital in Jakarta, Indonesia, by comparing the door-to-device (DTD) time and thrombolysis in myocardial infarction (TIMI) flow after angioplasty between two periods of admission: during the outbreak of COVID-19 (March 1 to May 31, 2020) and before the outbreak (March 1, to May 31, 2019). Overall, there was a relative reduction of 44% for STEMI admission during the outbreak ( n = 116) compared with before the outbreak ( N = 208). Compared with before the outbreak period ( n = 141), STEMI patients who admitted during the outbreak and received primary angioplasty ( n = 70) had similar median symptom onset-to-angioplasty center admission (360 minutes for each group), similar to radial access uptake (90 vs. 89.4%, p = 0.88) and left anterior descending infarct-related artery (54.3 vs. 58.9%, p = 0.52). The median DTD time and total ischemia time were longer (104 vs. 81 minutes, p < 0.001, and 475.5 vs. 449 minutes, p = 0.43, respectively). However, the final achievement of TIMI 3 flow was similar (87.1 vs. 87.2%), and so was the in-hospital mortality (5.7 vs. 7.8%). During the COVID-19 outbreak, we found a longer DTD time for primary angioplasty, but the achievement of final TIMI 3 flow and in-hospital mortality were similar as compared with before the outbreak. Thus, primary angioplasty should remain the standard of care for STEMI during the COVID-19 outbreak.

Association of gender with clinical outcomes of patients with acute ST-segment elevation myocardial infarction presenting with acute heart failure.

BACKGROUND: There is limited data evaluating the sex differences in outcomes of patients with ST-segment elevation myocardial infarction presenting with acute heart failure. We compared the outcomes between women and men with ST-segment elevation myocardial infarction presenting with acute heart failure (Killip classification ≥II). METHOD: All ST-segment elevation myocardial infarction patients presenting to the emergency department of a cardiovascular center in Jakarta, Indonesia, from 1 February 2011 to 30 August 2019 were retrospectively analyzed. RESULTS: Of 6557 patients recorded, 929 were women, and 276 (4.2%) presented with acute heart failure. Compared with men with acute heart failure (N = 1540), women who presented with acute heart failure were older (63 ± 10 vs. 57 ± 10 years, P < 0.001), had a greater proportion of thrombolysis in myocardial infarction risk score >4 (85% vs. 73%, P < 0.001), received fewer primary angioplasty and in-hospital fibrinolytic therapy (40% vs. 48%, P = 0.004 and 1.1% versus 3.5%, P = 0.03, respectively), and had longer median door-to-device and total ischemia times (96 vs. 83 minutes, P = 0.001, and 516 versus 464 minutes, P = 0.02, respectively). Multivariate analysis showed that women and men with acute heart failure were each associated with increased risk of in-hospital mortality (odds ratio: 4.70; 95% confidence interval: 3.28-6.73 and odds ratio: 4.75; 95% confidence interval: 3.84-5.88, respectively), and this remained relatively unchanged even among patients with acute heart failure who had undergone reperfusion therapy (odds ratio: 5.35; 95% confidence interval: 3.01-9.47 and odds ratio: 5.19; 95% confidence interval: 3.80-7.08, respectively). CONCLUSION: In our population, women with ST-segment elevation myocardial infarction presenting with acute heart failure had relatively similar risk of early mortality with their male counterpart (≈5-fold), thus should receive evidence-based treatment.

Association of microRNA-224-3p and microRNA-155-5p expressions with plasma long pentraxin 3 concentration and coronary microvascular obstruction following primary angioplasty for acute ST-segment elevation myocardial infarction.

OBJECTIVE: Pro-inflammatory stimuli induce a variety set of microRNAs (miRs) expression that regulate long pentraxin-3 (PTX3) protein, which associates with a procoagulant state in the endothelial cells. We evaluated, for the first time in human, the association of miR-224-3p and miR-155-5p expressions with plasma PTX3 concentration and coronary microvascular obstruction (MVO) in patients with acute ST-segment elevation myocardial infarction (STEMI) with symptom onset ≤ 12 h and treated by primary angioplasty. Blood samples for miRs and PTX3 measurement were drawn at emergency department presentation, and were measured by TaqMan real-time PCR and human ELISA kit, respectively. RESULTS: Of the 217 patients (median age: 54 years, male: 88%), 130 (60%) had angiographic MVO. Spearman analysis showed no correlation between miR-224-3p and miR-155-5p expressions with plasma PTX3 concentration. After adjustment with sex, age, diabetes mellitus, and plasma PTX3 concentration, miR-224-3p ≥ median group was associated with angiographic MVO (odds ratio, 2.60; 95% confidence interval, 1.24 to 5.44, p = 0.01). This study suggests that miR-224-3p and miR-155-5p expressions did not correlate with plasma PTX3 concentration. However, miR-224-3p expression associates with angiographic MVO following primary angioplasty for STEMI. Future studies are needed to identify the specific gene/protein related with miR-224-3p expression in MVO.

"Door-In to Door-Out" Delay in Patients with Acute ST-Segment Elevation Myocardial Infarction Transferred for Primary Percutaneous Coronary Intervention in a Metropolitan STEMI Network of a Developing Country.

Background Routine performance measures of primary percutaneous coronary intervention (PCI) within an ST-segment elevation myocardial infarction (STEMI) network are needed to improve care. Objective We evaluated the door-in to door-out (DI-DO) delays at the initial hospitals in STEMI patients as a routine performance measure of the metropolitan STEMI network. Patients and Methods We retrospectively analyzed the DI-DO time from 1,076 patients with acute STEMI who were transferred by ground ambulance to a primary PCI center for primary PCI between 4 October 2014 and 1 April 2019. Correlation analysis between DI-DO times and total ischemia time was performed using Spearman's test. Logistic regression analyses were used to find variables associated with a longer DI-DO time. Results Median DI-DO time was 180 minutes (25th percentile to 75th percentile: 120-252 minutes). DI-DO time showed a positive correlation with total ischemia time ( r = 0.4, p < 0.001). The median door-to-device time at the PCI center was 70 minutes (25th percentile to 75th percentile: 58-88 minutes). Multivariate analysis showed that women patients were independently associated with DI-DO time > 120 minutes (odds ratio 1.55, 95% confidence interval 1.03 to 2.33, p = 0.03). Conclusion The DI-DO time reported in this study has not reached the guideline recommendation. To improve the overall performance of primary PCI in the region, interventions aimed at improving the DI-DO time at the initial hospitals and specific threat for women patients with STEMI are possibly the best efforts in improving the total ischemia time.

Association of Hyperglycemia and Final TIMI Flow with One-Year Mortality of Patients with Acute ST-Segment Elevation Myocardial Infarction Undergoing Primary PCI.

The association of hyperglycemia at admission and final thrombolysis in myocardial infarction (TIMI) flow with 1-year mortality of patient with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) has not much been explored. We evaluated the association of hyperglycemia and final TIMI flow with 1-year mortality in patients with acute STEMI who underwent primary PCI. We retrospectively analyzed 856 patients with STEMI who underwent primary PCI in a tertiary care academic center between January 2014 and July 2016. Based on the receiver operating characteristics curve, the cutoff used for hyperglycemia in this study was greater than or equal to 169 mg/dL. Cox proportional hazard model was used to determine the association of hyperglycemia and TIMI flow with 1-year mortality. Compared with patients with lower blood glucose level (<169 mg/dL; n = 549), a greater proportion of patients who presented with hyperglycemia (≥169 mg/dL; n = 307) had final TIMI flow 0 to 1 (3.3 vs. 0.5%; adjusted odds ratio = 5.58, 95% confidence interval [CI] 1.30-23.9, p = 0.02). Hyperglycemia was associated with an increased risk for 1-year mortality (adjusted hazard ratio [HR]= 2.0, 95% CI: 1.13-3.53, p = 0.017). Multivariable Cox regression showed that the interaction of hyperglycemia and final TIMI flow 0 to 1 was associated with an elevated risk for 1-year mortality (adjusted HR= 9.4, 95% CI: 2.34-37.81, p = 0.002). A higher proportion of patients with acute STEMI who presented with hyperglycemia had final TIMI flow 0 to 1 after primary PCI. The interaction of hyperglycemia and final TIMI flow 0 to 1 was associated with an increased risk for 1-year mortality. This study suggests that aggressive control of hyperglycemia prior to primary PCI may facilitate better angiographic and clinical outcomes after primary PCI.

Two Wire System and Modified Olive Tip to Facilitate Implantation of Fenestrated TEVAR in Patient with Proximal Descending Aortic Pathology: First Two Cases.

INTRODUCTION: Although Fenestrated TEVAR (F-TEVAR) has been considered to be a more physiologic approach to treat proximal descending aortic pathology, its application is still limited due to availability, cost and technical difficulties. We introduce a new design of fenestrated stent graft with a new delivery system and successfully performed first in human implantation in two patients, one with an aortic aneurysm and one with an acute aortic dissection. MATERIALS AND METHODS: The design of these two wires fenestrated stent graft include creation of an additional lumen at the side of the olive tip during manufacture, from which an additional wire can be introduced for a side branch passing into the fenestration, running inside the stent graft and exit the delivery sheath through additional hub. The two wires will facilitate delivery and deployment of the stent graft. One patient with descending aortic aneurysm and another with Stanford B aortic dissection is included in this first in human study. RESULTS: The aneurysm and dissection were completely excluded immediately after the TEVAR. Six month follow up CT showed good position of the stent graft and patent LSA in both patients. In the patient with aortic dissection, expansion of the true lumen and partial thrombosis of the false lumen was seen. CONCLUSIONS: This is a report of a two wire system in 2 patients with distal aortic arch pathology demonstrating a good technical and clinical success using pre-cannulated fenestrations through a modified nose cone olive. LEVEL OF EVIDENCE: Level 4, report of two cases.

Two-year mortality of primary angioplasty for acute myocardial infarction during regular working hours versus off-hours.

BACKGROUND: Studies with short-term follow-up found higher mortality in patients with STEMI who underwent primary PCI during off-hours as compared to regular working hours. We analyzed the interaction between one and two-year survival of patients with STEMI who underwent primary PCI during regular working hours and off-hours in a tertiary care academic teaching hospital. METHODS: A total of 1126 STEMI patients treated with primary PCI between 2008 and 2013 were analyzed. Two-years follow-up were available in 941 (83%) patients. Multivariable survival analysis was used to estimate the relationship between treatment during off-hours versus regular hours and the incidence of all-cause mortality at 2-years follow-up. Logistic regression was used to calculate interaction p-values between time of admission and time (between ≤1 year and ≤2 year). RESULTS: At 2-years, the mortality rate of patients admitted during off-hours and regular hours was similar (15% vs. 19%; adjusted hazard ratio 0.77; 95% confidence interval 0.52-1.16). Of the 941 patients, those who admitted during off-hours (N = 717) had similar median door-to-device time (94 min vs. 91 min), final Thrombolysis In Myocardial Infarction 3 flow grade (93% vs. 91%) and use of dual antiplatelet within 24 h (96% vs. 98% respectively) as compared with regular hours admission (N = 224). There were no mortality difference observed between one year and two years (p interaction >0.05). CONCLUSION: In this analysis, the similar mortality observed at one year between patients with STEMI treated by primary PCI during off-hour and regular hour were maintained at two years.

Hospital outcomes in STEMI patients after the introduction of a regional STEMI network in the metropolitan area of a developing country.

Aims: Data on the long-term outcomes of STEMI patients treated via a network in Asian countries are very limited. We aimed to evaluate the characteristics and outcomes of STEMI patients at two different periods, before and five years after the establishment of a regional STEMI network in Jakarta, Indonesia. Methods and results: Out of 6,291 patients with STEMI admitted to hospital between January 2008 to January 2016, we compared the characteristics and outcomes of STEMI patients from two different periods, January 2008 to July 2009 (before instalment of the STEMI network, N=624), and from January 2015 to January 2016 (five years after the start of the network, N=1,052). The PCI hospital is an academic tertiary care cardiac hospital and initiated the regional STEMI network in 2010. Logistic regression was used to determine the adjusted association between treatment in the latter period and mortality. Compared with data from 2008/2009, in the 2015/2016 period, more primary PCI procedures were performed (N=589 [56%] vs. N=176 [28%], p<0.001), fewer patients did not receive reperfusion therapy (37% vs. 59%, p<0.001), and median door-to-device (DTD) times were shorter (82 vs. 94 minutes, p<0.001). Overall in-hospital mortality decreased from 9.6% to 7.1% (adjusted odds ratio 0.72, 95% CI: 0.50 to 1.03, p=0.07). Conclusions: Half a decade after the implementation of the STEMI network in Jakarta, Indonesia, the result is better and faster care for patients with STEMI and this has been associated with lower in-hospital mortality.

Characteristics, treatment and in-hospital outcomes of patients with STEMI in a metropolitan area of a developing country: an initial report of the extended Jakarta Acute Coronary Syndrome registry.

OBJECTIVE: We studied the characteristics of patients with ST segment elevation myocardial infarction (STEMI) after expansion of a STEMI registry as part of the STEMI network programme in a metropolitan city and the surrounding area covering ∼26 million inhabitants. DESIGN: Retrospective cohort study. SETTING: Emergency department of 56 health centres. PARTICIPANTS: 3015 patients with acute coronary syndrome, of which 1024 patients had STEMI. MAIN OUTCOME MEASURE: Characteristics of reperfusion therapy. RESULTS: The majority of patients with STEMI (81%; N=826) were admitted to six academic percutaneous coronary intervention (PCI) centres. PCI centres received patients predominantly (56%; N=514) from a transfer process. The proportion of patients receiving acute reperfusion therapy was higher than non-reperfused patients (54% vs 46%, p<0.001), and primary PCI was the most common method of reperfusion (86%). The mean door-to-device (DTD) time was 102±68 min. In-hospital mortality of non-reperfused patients was higher than patients receiving primary PCI or fibrinolytic therapy (9.1% vs 3.2% vs 3.8%, p<0.001). Compared with non-academic PCI centres, patients with STEMI admitted to academic PCI centres who underwent primary PCI had shorter mean DTD time (96±44 min vs 140±151 min, p<0.001), higher use of manual thrombectomy (60.2% vs13.8%, p<0.001) and drug-eluting stent implantation (87% vs 69%, p=0.001), but had similar use of radial approach and intra-aortic balloon pump (55.7% vs 67.2%, and 2.2% vs 3.4%, respectively). In patients transferred for primary PCI, TIMI risk score ≥4 on presentation was associated with a prolonged door-in to door-out (DI-DO) time (adjusted OR 2.08; 95% CI 1.09 to 3.95, p=0.02). CONCLUSIONS: In the expanded JAC registry, a higher proportion of patients with STEMI received reperfusion therapy, but 46% still did not. In developing countries, focusing the prehospital care in the network should be a major focus of care to improve the DI-DO time along with improvement of DTD time at PCI centres.
