Discrepancy between plaque vulnerability and functional severity of angiographically intermediate coronary artery lesions. Cardiovasc Interv Ther 2022; 37:691-698. [PMID: 35260967 DOI: 10.1007/s12928-022-00851-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Accepted: 02/25/2022] [Indexed: 11/02/2022]
Abstract
This study sought to investigate the relationship between physiological severity and plaque vulnerability of intermediate coronary artery stenoses as assessed by fractional flow reserve (FFR) and near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS). We included vessels where both FFR and NIRS-IVUS were performed. A positive FFR was defined as FFR ≤ 0.80. Lipid core burden index of the entire target vessel (TV-LCBI), maximum LCBI in 4 mm (maxLCBI4mm), and maximum plaque burden (PB) were evaluated using NIRS-IVUS. A vulnerable plaque was defined as a lipid-rich plaque (maxLCBI4mm ≥ 400) with large PB (≥ 70%). A total of 59 vessels of 45 patients were included. Median FFR value was 0.75 [interquartile 0.72, 0.82]. An FFR value of ≤ 0.80 was observed in 42 vessels (71%). TV-LCBI (correlation coefficient [CC] = - 0.331, p = 0.011), lesion length (CC = - 0.350, p = 0.007), and PB (CC = - 0.230, p = 0.080) negatively correlated with FFR value, while maxLCBI4mm did not (CC = - 0.156, p = 0.24). The prevalence of vulnerable plaques (26.2% vs. 29.4%, p > 0.99) and mean TV-LCBI, maxLCBI4mm, and PB values were not significantly different between the vessels with FFR ≤ 0.80 and those with FFR > 0.80. In multivariable logistic models, diabetes mellitus (p = 0.003) and hemoglobin A1c (p = 0.012) were associated with the presence of a vulnerable plaque. In conclusion, the results of the present study suggested that FFR may reflect total lipid burden but not necessarily plaque vulnerability. In patients with coronary artery disease and a high likelihood of rapid atherosclerosis progression, such as diabetes mellitus patients, assessing plaque vulnerability in addition to the functional severity of coronary artery lesions may help stratify better the risk of future events.

Abstract
Chronic kidney disease (CKD) increases the risk of death and other poor outcomes in patients with cardiovascular diseases. This study investigated the relation between the institutional CKD percutaneous coronary intervention (PCI) volume and in-hospital clinical outcomes in patients with CKD. Among 1,199,901 patients who underwent PCI in 2014 to 2018 from the Japanese nationwide registry, we analyzed 220,509 patients with CKD. Patients were classified into quartiles (Q) according to the mean annual institutional CKD-PCI volume (Q1 <42 PCIs/year, Q2 <74 PCIs/year, Q3 <124 PCIs/year, Q4 ≥125 PCIs/year). The primary outcome was a composite of in-hospital death and periprocedural complications. The mean age of patients was 73 ± 10 years, and 36% (n = 78,332) were on dialysis. PCI was more likely to be performed with rotational atherectomy devices in high-volume institutions. Contrast volume was lower, the rate of radial access PCI was higher, and door-to-balloon time (for ST-elevation myocardial infarction) was shorter in the highest quartile institutions. Primary outcomes were observed in 6,539 patients (3.0%). The crude rate of the primary outcome was lowest in institutions with the highest PCI volume (Q1 3.4%, Q2 3.0%, Q3 3.0%, Q4 2.4%, p <0.001); higher PCI volume was associated with reduced frequency of the primary outcome (odds ratio [95% confidence interval] relative to Q1:Q2, 0.89 [0.83 to 0.96]; Q3 0.90 [0.84 to 0.97]; and Q4 0.76 [0.84 to 0.97]). In conclusion, the procedural characteristics and outcomes of PCI differed significantly by institutional volume in patients with CKD. When considering revascularization among these patients, institutional CKD-PCI volume needs to be incorporated in decision-making.

Abstract
Slow flow during primary percutaneous coronary intervention (PCI) is a common complication. Our group showed that the stent (or post-balloon) diameter-to-vessel diameter ratio was inversely associated with slow flow phenomenon. We advocated the utility of modest stent expansion strategy, which was defined as the stent (or post-balloon) diameter-to-culprit vessel diameter ratio < 0.71, for prevention of slow flow phenomenon. This study aimed to compare the long-term outcomes in patients with acute myocardial infarction (AMI) between the modest stent expansion strategy and the aggressive stent expansion strategy (the stent diameter-to-culprit vessel diameter ratio ≥ 0.71). We included 584 AMI patients, which were divided 177 patients in the modest stent expansion group and 146 patients in the aggressive stent expansion group. The primary endpoint was major adverse cardiac events (MACE), which was defined as a composite of cardiac death, ischemia driven target vessel revascularization, and stent thrombosis. The slow flow after stent deployment was more frequently observed in the aggressive stent expansion group (24.0%) than in the modest stent expansion group (4.0%) (P < 0.001). The Kaplan-Meier curves revealed that MACE was comparable between the two groups (P = 0.64). The multivariate COX hazard model showed the non-significant association between the modest stent expansion strategy and MACE (vs. aggressive stent expansion: hazard ratio 1.005, 95% confidence interval 0.619-3.242, P = 0.41). In conclusion, the modest stent expansion strategy was not associated with long-term MACE. Therefore, the modest stent expansion strategy may be a good choice for the culprit lesion of AMI.

Abstract
The situation around primary percutaneous coronary intervention (PCI) has dramatically changed since coronavirus disease 2019 (COVID-19) pandemic. The impact of COVID-19 pandemic on clinical outcomes as well as door-to-balloon time (DTBT), which is known as one of the indicators of early reperfusion, has not been fully investigated in patients with ST-elevation acute myocardial infarction (STEMI). The purpose of this study was to compare DTBT and in-hospital outcomes in patients with STEMI between before versus after COVID-19 pandemic. The primary interest was DTBT and the incidence of in-hospital outcomes including in-hospital death. We included 330 patients with STEMI who underwent primary PCI, and divided them into the pre COVID-19 group (n = 209) and the post COVID-19 group (n = 121). DTBT was significantly longer in the post COVID-19 group than in the pre COVID-19 group (p < 0.001), whereas the incidence of in-hospital death was comparable between the 2 groups (p = 0.238). In the multivariate logistic regression analysis, chest CT before primary PCI (OR 4.64, 95% CI 2.58-8.34, p < 0.001) was significantly associated with long DTBT, whereas chest CT before primary PCI (OR 0.76, 95% CI 0.29-1.97, p = 0.570) was not associated with in-hospital death after controlling confounding factors. In conclusion, although DTBT was significantly longer after COVID-19 pandemic than before COVID-19 pandemic, in-hospital outcomes were comparable between before versus after COVID-19 pandemic. This study suggests the validity of the screening tests including chest CT for COVID-19 in patients with STEMI who undergo primary PCI.

Abstract
Aims Although primary percutaneous coronary intervention (PCI) and mechanical circulatory support (MCS), such as extracorporeal membrane oxygenation (ECMO) or intra-aortic balloon pumping (IABP), have been widely used for acute myocardial infarction (AMI) patients with cardiogenic shock (AMICS), their in-hospital mortality remains high. This study aimed to investigate the association of cardiovascular healthcare resources with 30-day mortality in AMICS. Methods and results This was an observational study using a Japanese nationwide administrative data (JROAD-DPC) of 260 543 AMI patients between April 2012 and March 2018. Of these, 45 836 AMICS patients were divided into three categories based on MCS use: with MCS (ECMO with/without IABP), IABP only, or without MCS. Certified hospital density and number of board-certified cardiologists were used as a metric of cardiovascular healthcare resources. We estimated the association of MCS use, cardiovascular healthcare resources, and 30-day mortality. The 30-day mortality was 71.2% for the MCS, 23.9% for IABP only, and 37.8% for the group without MCS. The propensity score-matched and inverse probability-weighted Cox frailty models showed that primary PCI was associated with a low risk for mortality. Higher hospital density and larger number of cardiologists in the responsible hospitals were associated with a lower risk for mortality. Conclusion Although the 30-day mortality remained extremely high in AMICS, indication of primary PCI and improvement in providing cardiovascular healthcare resources associated with the short-term prognosis of AMICS.

Variation in in-hospital mortality and its association with percutaneous coronary intervention-related bleeding complications: A report from nationwide registry in Japan. PLoS One 2021; 16:e0261371. [PMID: 34898658 PMCID: PMC8668123 DOI: 10.1371/journal.pone.0261371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Accepted: 11/29/2021] [Indexed: 11/22/2022] Open
Abstract
Large-scale registries have demonstrated that in-hospital mortality after percutaneous coronary intervention (PCI) varies widely across institutions. However, whether this variation is related to major procedural complications (e.g., bleeding) is unclear. In this study, institutional variation in in-hospital mortality and its association with PCI-related bleeding complications were investigated. We analyzed 388,866 procedures at 718 hospitals performed from 2017 to 2018, using data from a nationwide PCI registry in Japan. Hospitals were stratified into quintiles according to risk-adjusted in-hospital mortality (very low, low, medium, high, and very high). Incidence of bleeding complications, defined as procedure-related bleeding events that required a blood transfusion, and in-hospital mortality in patients who developed bleeding complications were calculated for each quintile. Overall, 4,048 (1.04%) in-hospital deaths and 1,535 (0.39%) bleeding complications occurred. Among patients with bleeding complications, 270 (17.6%) died during hospitalization. In-hospital mortality ranged from 0.22% to 2.46% in very low to very high mortality hospitals. The rate of bleeding complications varied modestly from 0.27% to 0.57% (odds ratio, 1.95; 95% confidence interval, 1.58–2.39). However, mortality after bleeding complications markedly increased by quintile and was 6-fold higher in very high mortality hospitals than very low mortality hospitals (29.0% vs. 4.8%; odds ratio, 12.2; 95% confidence interval, 6.90–21.7). In conclusion, institutional variation in in-hospital mortality after PCI was associated with procedure-related bleeding complications, and this variation was largely driven by differences in mortality after bleeding complications rather than difference in their incidence. These findings underscore the importance of efforts toward reducing not only bleeding complications but also, even more importantly, subsequent mortality once they have occurred.

[PMID: 34808210 DOI: 10.1016/j.ijcard.2021.11.047] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 11/02/2021] [Accepted: 11/16/2021] [Indexed: 11/05/2022]
Abstract
BACKGROUND Vasospastic angina (VSA) is reportedly associated with several clinical characteristics such as smoking and high-density lipoprotein (HDL) cholesterol, in which gender differences are present. For instance, smoking rates among men are higher than those among women, and a normal range of HDL cholesterol differs across genders. However, their impact between men and women on VSA is unclear. METHODS A total of 797 patients (427 men and 370 women) undergoing intracoronary acetylcholine (ACh) provocation test to diagnose VSA were included. The positive ACh provocation test was defined as angiographic vasospasm accompanied by chest pain and/or ischemic electrocardiographic changes. Factors contributing to VSA across genders were evaluated by multivariable analyses. RESULTS Of 797 patients, 414 (51.9%) had positive ACh provocation test. The incidence of positive ACh test was higher in men than in women (56.9% vs. 46.2%, p = 0.003). In the entire study population, current smoking and a lower HDL cholesterol level were determined as factors associated with VSA. In both men and women, an HDL cholesterol level was identified as a factor contributing to positive ACh test. CONCLUSIONS Among patients suspected for VSA, men as compared with women were more likely to have positive ACh provocation test. While current smoking and an HDL cholesterol level were associated with VSA in the entire study population, a lower HDL cholesterol level was determined as the only factor contributing to positive ACh test across genders, suggesting that HDL cholesterol plays important roles in the mechanism of VSA.

Abstract
In percutaneous coronary intervention (PCI) to the culprit lesion of acute myocardial infarction (AMI), unsuccessful guidewire crossing causes immediate poor outcomes. It is important to determine the factors associated with unsuccessful guidewire crossing in AMI lesions. The purpose of this study was to find factors associated with difficulty in crossing the culprit lesion of AMI. We defined the difficult group when the guidewire used to cross the culprit lesion was a polymer jacket type guidewire or a stiff guidewire. We included 937 patients, and divided those into the non-difficult group (n = 876) and the difficult group (n = 61). Proximal reference diameter was significantly smaller in the difficult group than in the non-difficult group (p < 0.001), and degree of calcification was severer in the difficult group than in the non-difficult group (p < 0.001). In the multivariate stepwise logistic regression analysis, proximal reference diameter [odds ratio (OR) 0.313, 95% confidence interval (CI) 0.185–0.529, p < 0.001)], previous PCI (OR 3.065, 95% CI 1.612–5.830, p = 0.001), moderate-severe calcification (OR 4.322, 95% CI 2.354–7.935, p < 0.001), blunt type obstruction (OR 12.646, 95% CI 6.805–23.503, p < 0.001), and the presence of collateral to the culprit lesion (OR 2.110, 95% CI 1.145–3.888, p = 0.017) were significantly associated with difficulty in crossing the culprit lesion. In conclusion, previous PCI, calcification, blunt type obstruction, and the presence of collateral were associated with difficulty in crossing the culprit lesion, whereas proximal reference diameter was inversely associated with difficulty. Our study provides a reference to recognize the difficulty in crossing the culprit lesions of AMI for PCI operators, especially junior operators.

Effectiveness of hospital lipid-lowering protocol of intensive lipid-lowering therapy for patients with acute coronary syndrome. J Cardiol 2021; 79:391-399. [PMID: 34706839 DOI: 10.1016/j.jjcc.2021.10.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 09/27/2021] [Accepted: 09/30/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND AIMS The achievement of a target low-density lipoprotein cholesterol (LDL-C) level in clinical settings is often insufficient. A hospital lipid-lowering protocol (HLP) could be effective for providing the optimal lipid-lowering therapy. Herein we determined the effectiveness of a HLP for acute coronary syndrome (ACS) patients. METHODS We retrospectively analyzed 1,497 patients who underwent successful percutaneous coronary intervention for ACS at our hospital (November 2011 to May 2020). In December 2018, we introduced a HLP that included the prescription of the maximum tolerated dose of statin, ezetimibe, and eicosapentaenoic acid. We compared the lipid profile and clinical outcomes at 12 months between before (Control group: 1,219 patients) and after the HLP's introduction (HLP group: 278 patients). The primary outcome was the achievement rate of LDL-C < 1.8 mmol/L (70 mg/dL). The key secondary outcomes were the change value and ratio of LDL-C plus the major adverse cardiac events (MACE), defined as a composite of cardiac death, myocardial infarction, target vessel revascularization, and stent thrombosis. RESULTS The achievement rate of LDL-C < 1.8 mmol/L was significantly higher in the HLP group than in the Control group (58% vs. 27%, p < 0.01). The HLP group's change ratio and LDL-C values were significantly lower than those of the Control group (-39.5 [-55.1, -13.2]% vs. -20.4 [-38.4, 0]%, p < 0.001; -41 [-69, -11] mg/dL vs. -21 [-38, 0] mg/dL, p < 0.001). MACE was similar between the groups (16.9 vs. 15.5%, p = 0.66). CONCLUSION Implementing a HLP for ACS patients improved the achievement of target LDL-C at 12 months.

Impact of Serum Uric Acid Level on Systemic Endothelial Dysfunction in Patients with a Broad Spectrum of Ischemic Heart Disease. J Clin Med 2021; 10:jcm10194530. [PMID: 34640550 PMCID: PMC8509425 DOI: 10.3390/jcm10194530] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 09/27/2021] [Accepted: 09/28/2021] [Indexed: 11/25/2022] Open
Abstract
Previous studies indicated that serum uric acid (SUA) level is a marker of endothelial function in subsets of ischemic heart disease (IHD). In the present study, we aimed to evaluate the relation between the SUA level and endothelial function in patients with a broad spectrum of IHD, including obstructive coronary artery disease (CAD) and ischemia with no obstructive CAD (INOCA). Three prospective studies and one retrospective study were pooled, in which the SUA level was measured, and systemic endothelial function was assessed using the reactive hyperemia index (RHI). The primary endpoint of the present study was a correlation of the SUA level with RHI. A total of 181 patients with a broad spectrum of IHD were included, among whom, 46 (25%) had acute coronary syndrome presentation and 15 (8%) had INOCA. Overall, the SUA level was negatively correlated with the RHI (r = −0.22, p = 0.003). Multivariable analysis identified the SUA level and INOCA as significant factors associated with RHI values. In conclusion, in patients with a broad spectrum of IHD, including obstructive epicardial CAD (chronic and acute coronary syndromes) and INOCA, the SUA level was significantly and negatively correlated with systemic endothelial function assessed with the RHI. INOCA, rather than obstructive CAD, was more associated with endothelial dysfunction.

Abstract
BACKGROUND Balloon pulmonary angioplasty (BPA), a novel technique initially introduced as a treatment for inoperable chronic thromboembolic pulmonary hypertension, is now increasingly being performed in a broader spectrum of patients. Here, we performed a time-trend analysis of the characteristics and in-hospital outcomes of patients who underwent BPA in Japan, using data extracted from nationwide procedure-based registration system. METHODS The Japanese Structural Heart Disease (J-SHD) registry was established and sponsored by the Japanese Association of Cardiovascular Intervention and Therapeutics and aims to provide basic statistics on the performance of structural interventions in Japan. J-SHD registers cases from approximately 200 institutions, representing more than 90% of SHD intervention-performing hospitals in the nation. We analysed the registered BPA data elements from January 2015 to December 2018. Successful BPA was defined as a session in which a physician successfully treated all targeted lesions. RESULTS There were a total of 2512 BPA sessions; the number of institutions and registered sessions increased from 30 to 50 sites and from 479 to 852 sessions during the study period, respectively. The average age of the patients was 66±13 years, and 72.1% were women. In-hospital death was observed in 0.2%, and the total complications rate was 5.3%. The preoperative and postoperative mean pulmonary artery pressure were 32±11 mm Hg and 30±10 mm Hg, respectively. CONCLUSION The number of BPA sessions increased during the study period, with an acceptable in-hospital complication rate.

Abstract
Objective Since patients with thoracic aortic aneurysm (TAA)/abdominal aortic aneurysm (AAA) are often complicated with coronary artery disease, it is common for those patients to undergo percutaneous coronary intervention (PCI). The ankle brachial index (ABI) is usually measured in patients with TAA/AAA to screen the presence of peripheral arterial disease. The present study investigated the association between the ABI and clinical outcomes following PCI in patients with TAA/AAA. Methods We divided 200 TAA/AAA patients who underwent PCI into a normal ABI group (n=137) and an abnormal ABI group (n=63) according to the ABI cut-off level of 1.00. The primary endpoint was one-year major adverse cardiovascular events (MACE), defined as the composite of cardiovascular death, non-fetal myocardial infarction, stroke, target vessel revascularization, and hospitalization for heart failure. Results Mean ABIs in the normal and abnormal ABI groups were 1.12±0.09 and 0.86±0.11, respectively (p<0.01). Kaplan-Meier curves showed MACE were more frequent in the abnormal ABI group than in the normal ABI group (p=0.01). A multivariate Cox hazard analysis revealed that an abnormal ABI was significantly associated with 1-year MACE (vs. ABI ≥1.0: HR 3.02, 95% confidence interval 1.00-9.08, p=0.049). Conclusion Among patients with TAA/AAA who underwent PCI, abnormal ABI was significantly associated with 1-year MACE, suggesting the utility of the ABI measurement in this high-risk population.

Abstract
Background Performance of percutaneous coronary intervention (PCI) in side-branch vessels (SB-PCI) has not been fully investigated despite the technical advancement of PCI. Methods We investigated 257,492 patients registered in the Japanese nationwide PCI registry from January to December 2018; 199,767 (78%) underwent PCI for major vessel PCI (MV-PCI), 21,555 (8.4%) underwent SB-PCI, and 24,862 (9.6%) underwent PCI for both vessels (SB + MV-PCI). The frequencies of primary composite adverse events, defined as in-hospital mortality and procedural complications (i.e., peri-procedural myocardial infarction, tamponade, new-onset cardiogenic shock, stent thrombosis, emergent surgery, and bleeding), and PCI for restenotic lesions were investigated. Their association with institutional frequency of each PCI was also investigated. Results Fewer drug-eluting stents (66% vs. 86%) and more drug-coated balloons (23% vs. 9%) were used in SB-PCI than in MV-PCI (p < 0.001). Pre-procedure non-invasive testing was similarly performed in SB-PCI and MV-PCI (57% vs. 61%). The composite endpoint was observed in 0.7%, 1.9%, and 2.2% of the SB-PCI, SB + MV-PCI, and MV-PCI groups, respectively (p < 0.001). Institutional frequency of SB-PCI was inversely associated with the composite-endpoint risk for all PCI procedures (odds ratio 1.37, 95% confidence interval 1.04–1.81 in the lowest tertile, with reference to the middle tertile, p = 0.02). Frequency of PCI for restenotic lesions was also inversely associated with the institutional frequency of MV-PCI (p < 0.001). Conclusion SB-PCI was performed safely with a low frequency of acute complications, and higher SB-PCI frequency presented a lower risk of in-hospital adverse events, albeit with a cost of an increase in PCI for restenotic lesions.

Abstract
Introduction In percutaneous coronary intervention (PCI) to atherosclerotic lesions in the right coronary artery (RCA), coronary artery dissection in the ostium of the RCA is a rare but fatal complication. Stent implantation to the ostium of RCA may be selected for the prevention of aorto-ostial dissection. Aim To find factors associated with aorto-ostial stent coverage to mild to moderate ostial stenosis during the treatment of severely narrowed non-ostial RCA lesions. Material and methods The primary interest was to find factors associated with ostial stent coverage using multivariate regression analysis. We included 236 patients who underwent intravascular ultrasound (IVUS)-guided PCI to severely narrowed RCA lesions with mild to moderate ostial stenosis, and divided those into the ostial-coverage group (n = 52) and the non-coverage group (n = 184). Results The prevalence of continuous ostial plaque detected by intravascular ultrasound (IVUS) was significantly greater in the ostial-coverage group (84.6%) than in the non-coverage group (52.9%) (p < 0.001). Multivariate logistic regression analysis revealed that continuous ostial plaque detected by IVUS (OR = 5.398, 95% CI: 2.322–12.553, p < 0.001) was significantly associated with ostial stent coverage after controlling confounding factors. Ischaemia-driven target vessel revascularization was less frequently observed in the ostial-coverage group than in the non-coverage group, without reaching statistical significance (p = 0.069). Conclusions Continuous ostial plaque detected by IVUS was significantly associated with ostial stent coverage to the mild to moderate stenosis when PCI to non-ostial, severely narrowed RCA lesions was performed. The use of IVUS may enhance the safety but may increase the total stent length in PCI to RCA.

Abstract
AIMS Peripheral arterial disease (PAD) is the well-known risk factor for cardiovascular events. Although low ankle-brachial index (ABI) is recognized as a risk factor in general population, low ABI without any symptoms of PAD has not been established as a prognostic marker in patients with acute myocardial infarction (AMI) yet. The purpose of this retrospective study was to examine whether asymptomatic low ABI was associated with long-term clinical outcomes in AMI patients without treatment history of PAD. METHODS We included 850 AMI patients without a history of PAD and divided them into the preserved ABI (ABI ≥ 0.9) group (n=760) and the reduced ABI (ABI <0.9) group (n=90) on the basis of the ABI measurement during the hospitalization. The primary endpoint was the major adverse cardiovascular events (MACE) defined as the composite of all-cause death, non-fatal myocardial infarction, and hospitalization for heart failure. RESULTS During the median follow-up duration of 497 days (Q1: 219 days to Q3: 929 days), a total of 152 MACE were observed. The Kaplan-Meier curves showed that MACE were more frequently observed in the reduced ABI group than in the preserved ABI group (p<0.001). The multivariate COX hazard analysis revealed that reduced ABI was significantly associated with MACE (hazard ratio 2.046, 95% confidence interval 1.344-3.144, p=0.001) after controlling confounding factors. CONCLUSIONS Reduced ABI was significantly associated with long-term adverse events in AMI patients without a history of PAD. Our results suggest the usefulness of ABI as a prognostic marker in AMI patients irrespective of symptomatic PAD.

Abstract
The clinical outcomes in acute myocardial infarction (AMI) patients with Killip class 3 are often inconsistent with those in the literature, and the factors associated with poor outcomes have not been sufficiently investigated. The purpose of this study was to identify factors associated with in-hospital death in AMI patients with Killip class 3. We included 205 AMI patients with Killip class 3, and divided them into a survived group (n = 189) and in-hospital death group (n = 16). The primary objective was to identify factors associated with in-hospital death using multivariate analysis. Age was significantly younger in the survived group than in the in-hospital death group (73.1 ± 11.2 versus 83.2 ± 6.2 years, P < 0.001). Systolic blood pressure (SBP) was significantly higher in the survived group than in the in-hospital death group (150.0 ± 31.2 versus 124.8 ± 25.3 mmHg, P = 0.002). The prevalence of TIMI thrombus grade ≥ 2 was significantly greater in the in-hospital death group than in the survived group (56.3 versus 22.2%, P = 0.005). In multivariate logistic regression analysis, in-hospital death was significantly associated with age [odds ratio (OR) 1.168, 95% confidence interval (CI) 1.061-1.287, P = 0.002] and TIMI thrombus grade ≥ 2 (versus ≤ 1: OR 5.743, 95% CI 1.717-19.214, P = 0.005), and inversely associated with SBP on admission (per 10 mmHg increase: OR 0.764, 95% CI 0.613-0.953, P = 0.017). In conclusion, in-hospital death was associated with age and coronary thrombus burden, and was inversely associated with SBP on admission in patients with Killip class 3. It may be important to recognize these high risk features to improve the clinical outcomes of patients with Killip class 3.

BACKGROUND Acute coronary syndrome (ACS) hospital survivors experience a wide array of late adverse cardiac events, despite considerable advances in the quality of care. We investigated 30-day and 1-year outcomes of ACS hospital survivors using a Japanese nationwide cohort.Methods and Results:We studied 20,042 ACS patients who underwent percutaneous coronary intervention (PCI) in 2017: 10,242 (51%) with ST-elevation myocardial infarction (STEMI), 3,027 (15%) with non-ST-elevation myocardial infarction (NSTEMI), and 6,773 (34%) with unstable angina (UA). The mean (±SD) age was 69.6±12.4 years, 77% of the patients were men, and 20% had a previous history of PCI. The overall 30-day all-cause, cardiac, and non-cardiac mortality rates were 3.0%, 2.4%, and 0.6%, respectively. The overall 1-year incidence of all-cause, cardiac, and non-cardiac death was 7.1%, 4.2%, and 2.8%, respectively. Compared with UA patients, STEMI patients had a higher risk of all fatal events, non-fatal ischemic stroke, and acute heart failure, and NSTEMI patients had a higher risk of heart failure. CONCLUSIONS The results from our ACS hospital survivor PCI database suggest the need to improve care for the acute myocardial infarction population to lessen the burden of 30-day mortality due to ACS, heart failure, and sudden cardiac death, as well as 1-year ischemic stroke and heart failure events.

Female sex as an independent predictor of high bleeding risk among East Asian percutaneous coronary intervention patients: A sex difference analysis. J Cardiol 2021; 78:431-438. [PMID: 34172350 DOI: 10.1016/j.jjcc.2021.05.016] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Revised: 05/12/2021] [Accepted: 05/16/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Sex differences in the outcomes following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) have been identified in Western countries. However, data on the long-term outcomes for bleeding events, particularly in East Asia where the aging population is growing rapidly and consists predominantly of women, remain scarce. METHODS We analyzed 2,494 ACS survivors from a multicenter PCI registry who underwent PCI between 2009 and 2012. The primary outcome was readmission for major bleeding at 2 years. Survival curves were generated with the cumulative incidence function. The adjusted hazard ratios were evaluated for the primary outcomes by sex using (1) Fine-Gray models and (2) Cox regression models. RESULTS There were 548 women (22.0%) in this cohort. The women were older (73.7 ± 10.8 years vs. 65.4 ± 11.8 years, p < 0.001), had a lower body mass index (23.0 ± 3.9 vs. 24.3 ± 3.6, p < 0.001), and had more comorbidities such as renal failure (49.4% vs. 36.3%, p < 0.001) and previous heart failure (8.4% vs. 4.5%, p < 0.001). Fewer women were discharged with statins (81.9% vs. 86.5%, p = 0.025) or beta blockers (70.6% vs. 77.1%, p = 0.007). During the 2-year follow-up, the unadjusted readmission rates for bleeding were higher among women (4.9% versus 2.4% at 2 years after discharge). Multivariable competing risk analysis with the Fine-Gray model and Cox regression model further demonstrated that female sex was associated with a higher risk of bleeding. CONCLUSIONS Among patients treated with PCI, women had a higher incidence of bleeding events requiring readmission. Sex disparities in the etiologies of readmission following PCI suggest the need for targeted treatment strategies. A strict follow-up after discharge could be beneficial for women to further reduce their risk.

Abstract
Despite the known association of cardiac rupture with acute myocardial infarction (AMI), it is still unclear whether the clinical characteristics are associated with the risk of in-hospital mortality in patients with AMI complicated by cardiac rupture. The purpose of this study was to investigate the association between the time of cardiac rupture occurrence and the risk of in-hospital mortality after AMI. We conducted a retrospective analysis of multicenter registry data from eight medical universities in Eastern Japan. From 10,278 consecutive patients with AMI, we included 183 patients who had cardiac rupture after AMI, and examined the incidence of in-hospital deaths during a median follow-up of 26 days. Patients were stratified into three groups according to the AMI-to-cardiac rupture time, namely the > 24-h group (n = 111), 24-48-h group (n = 20), and < 48-h group (n = 52). Cox proportional hazards regression analysis was used to estimate the hazard ratio (HR) and the confidence interval (CI) for in-hospital mortality. Around 87 (48%) patients experienced in-hospital death and 126 (67%) underwent a cardiac surgery. Multivariable Cox regression analysis revealed a non-linear association across the three groups for mortality (HR [CI]; < 24 h: 1.0, reference; 24-48 h: 0.73 [0.27-1.86]; > 48 h: 2.25 [1.22-4.15]) after adjustments for age, sex, Killip classification, percutaneous coronary intervention, blood pressure, creatinine, peak creatine kinase myocardial band fraction, left ventricular ejection fraction, and type of rupture. Cardiac surgery was independently associated with a reduction in the HR of mortality (HR [CI]: 0.27 [0.12-0.61]) and attenuated the association between the three AMI-to-cardiac rupture time categories and mortality (statistically non-significant) in the Cox model. These data suggest that the AMI-to-cardiac rupture time contributes significantly to the risk of in-hospital mortality; however, rapid diagnosis and prompt surgical interventions are crucial for improving outcomes in patients with cardiac rupture after AMI.

Comparison of the cost in percutaneous coronary intervention between ST-segment elevation myocardial infarction vs. non-ST-segment elevation myocardial infarction. Cardiovasc Interv Ther 2021; 37:293-303. [PMID: 33884579 DOI: 10.1007/s12928-021-00778-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 04/16/2021] [Indexed: 12/19/2022]
Abstract
Percutaneous coronary intervention (PCI) is a standard strategy for non-ST-segment elevation myocardial infarction (NSTEMI) as well as for ST-segment elevation myocardial infarction (STEMI). The device cost for PCI may be more expensive in NSTEMI, because the culprit lesion morphology may be more complex in NSTEMI. This study aimed to compare the total device cost of PCI between STEMI and NSTEMI. We included 504 patients with acute myocardial infraction (AMI) who underwent PCI, and divided those into a STEMI group (n = 286) and a NSTEMI group (n = 218). We compared the total device cost, the number of used devices, and procedure cost between the 2 groups. The total device cost was significantly higher in the NSTEMI group [¥371,300 (¥320,700-503,350)] than in the STEMI group [¥341,200 (¥314,200-410,475)] (p = 0.001), whereas the procedure cost was significantly higher in the STEMI group [¥343,800 (¥243,800-343,800)] than in the NSTEMI group [¥220,000 (¥216,800-243,800)] (p < 0.001). Drug eluting stent (85.3% vs. 76.1%, p = 0.029) and aspiration catheter (16.8% vs. 2.3%, p < 0.001) were more frequently used in the STEMI group, whereas rotablator (0.7% vs. 8.3%, p < 0.001) were more frequently used in the NSTEMI group. The multivariate logistic regression analysis revealed that NSTEMI was significantly associated with the high device cost (odds ratio 1.899, 95% confidence interval 1.166-3.093, p = 0.01). In conclusion, the total device cost for PCI was significantly higher in the culprit lesions of NSTEMI than in those of STEMI, whereas the procedure cost was significantly higher in the culprit lesions of STEMI than in those of NSTEMI.

Abstract
Healthcare systems worldwide have been overburdened by the coronavirus disease 2019 (COVID-19) outbreak. Accordingly, hospitals have had to implement strategies to profoundly reorganize activities, which have affected procedures such as primary percutaneous coronary interventions (PCIs). This study aimed to describe changes in PCI practices during the health emergency at the national level. The Japanese Association of Cardiovascular Intervention and Therapeutics performed provided serial surveys of institutions throughout Japan during the pandemic. The data obtained on December, 2020 and February 2021 (during the 2nd wave of pandemic) were compared with the data obtained on August 2020 (1st wave). Primary PCI for STEMI was performed as usual in 99.1%, 98.7%, and 97.5% of institutions in mid-August, mid-December, 2020 and mid-February, 2021, respectively. The COVID-19 screening tests rates in patients were significantly higher during the third wave than during the second wave (54.0% in mid-August, 2020 and 64.6% in mid-February, 2021, P = 0.002). In addition, hospitals reported that personal protective equipment was more available over time (66.4% in mid-August, 2020 and 83.8% in mid-February, 2021, P < 0.001). In conclusion, most institutions surveyed in Japan continued to perform primary PCI as usual for STEMI patients during the second and third waves of the COVID-19 pandemic. In addition, the COVID-19 screening tests were more frequently performed over time.

In-hospital Bleeding Outcomes of Oral Anticoagulant and Dual Antiplatelet Therapy During Percutaneous Coronary Intervention: An Analysis From the Japanese Nationwide Registry. J Cardiovasc Pharmacol 2021; 78:221-227.

Abstract
Supplemental Digital Content is Available in the Text. The type of periprocedural antithrombotic regimen that is the safest and most effective in percutaneous coronary intervention (PCI) patients on oral anticoagulant (OAC) therapy has not been fully investigated. We aimed to retrospectively investigate the in-hospital bleeding outcomes of patients receiving OAC and antiplatelet therapies during PCI using Japanese nationwide multicenter registry data. A total of 26,938 patients who underwent PCI with OAC and antiplatelet therapies between 2016 and 2017 were included. We investigated in-hospital bleeding requiring blood transfusion, mortality, and stent thrombosis according to the antithrombotic regimens used at the time of PCI: OAC + single antiplatelet therapy (double therapy) and OAC + dual antiplatelet therapy (triple therapy). The antiplatelet agents included aspirin, clopidogrel, and prasugrel. The OAC agents included warfarin and direct OACs. Adjusting the dose of OAC or intermitting OAC before PCI was at each operator's discretion. In the study population [mean age (SD), 73.5 (9.5) years; women, 21.5%], the double therapy and triple therapy groups comprised 5546 (20.6%) and 21,392 (79.4%) patients, respectively. Bleeding requiring transfusion was not significantly different between the groups [adjusted odds ratio (aOR), 0.700; 95% confidence interval (CI), 0.420–1.160; P = 0.165] (triple therapy as a reference). Mortality was not significantly different (aOR, 1.370; 95% CI, 0.790–2.360; P = 0.258). Stent thrombosis was significantly different between the groups (aOR, 3.310; 95% CI, 1.040–10.500; P = 0.042) (triple therapy as a reference). In conclusion, for patients on OAC therapy who underwent PCI, periprocedural triple therapy may be safe with respect to in-hospital bleeding risks. However, further investigations are warranted to establish the safety and efficacy of periprocedural triple therapy.

Abstract
Background:
We hypothesized that symptom presentation in patients with acute myocardial infarction (AMI) may affect their management and subsequent outcome. Methods and Results:
Using Rural AMI Registry data, 1,337 consecutive patients with AMI who underwent percutaneous coronary intervention were analyzed. Typical symptoms were defined as any symptoms of chest pain or pressure due to myocardial ischemia. We considered the specific symptoms of dyspnea, nausea, or vomiting as atypical symptoms. The primary outcome was 30-day mortality. There were 150 (11.2%) and 1,187 (88.8%) patients who presented with atypical and typical symptoms, respectively. Those who presented with atypical symptoms were significantly older (mean [±SD] age 74±12 vs. 68±13 years; P<0.001) and had a higher Killip class (46.7% vs. 21.8%; P<0.001) than patients presenting with typical symptoms. The prevalence of door-to-balloon time of ≤90 min was significantly lower in patients with atypical than typical symptoms (40.0% vs. 66.3%; P<0.001). At 30 days, there were 55 incidents of all-cause death. Multivariate Cox proportional hazards regression analysis revealed that symptom presentation was associated with 30-day mortality (hazard ratio 2.33; 95% confidence interval 1.20–4.38; P<0.05). Conclusions:
Atypical symptoms in patients with AMI are less likely to lead to timely reperfusion and are associated with increased risk of 30-day mortality.

Abstract
A method to manage ST-segment elevated myocardial infarction (STEMI) caused by very late stent thrombosis (VLST) has yet to be established. In this case series, we present several cases of STEMI caused by VLST, which were successfully revascularized using a perfusion balloon. Since the perfusion balloon (Ryusei: Kaneka Medix Corporation, Osaka, Japan) has the unique advantage of maintaining blood flow during balloon inflation, we can keep dilating the target lesion for more than several minutes. Extended inflation might work to prevent acute recoil, and to achieve optimal expansion without an additional stent. Our case series may provide a reasonable option for the treatment of VLST.

Abstract
BACKGROUND Clinical significance of neoatherosclerosis (NA) observed at very late phase remains undetermined. We sought to investigate the association between NA observed by optical coherence tomography (OCT) 3-7 years after stenting and subsequent clinical outcomes. METHODS We investigated previously implanted stents without stent failure in the institutional OCT database at Tsuchiura Kyodo General Hospital. Qualitative and quantitative OCT analyses were performed. In patient-based analysis, major adverse cardiac events (MACE) included all-cause death, non-fatal myocardial infarction, and clinically driven revascularization. MACE-free survival rate was compared between patients with any stent showing NA (NA group) and those without NA (non-NA group). In stent-based analysis, the stent failure including target-lesion revascularization and stent thrombosis after the belated OCT examination were assessed. RESULTS A total of 187 patients with 308 stents undergoing belated OCT examination 3-7 years after implantation were investigated. Median duration from implantation to the belated OCT was 4.8 (3.8-5.8) years and NA was identified in 48 stents (15.6%) in 36 patients (19.3%). In patient-based analysis, during the median of 2.9 (2.1-3.6) years after belated OCT, MACE occurred in 9 patients (25.0%) with at least one stent showing NA (NA group) and 9 patients (6.0%) without NA (non-NA group) (p=0.002). Cox regression analysis revealed that NA was an independent predictor of MACE [hazard ratio (HR) 4.14 (1.58- 10.8), p=0.004]. In stent-based analysis, 7 stent failures were documented (stents with NA 10.0% vs. stents without NA 0.8%, p<0.01). NA was a significant predictor of stent failure [HR 9.17 (1.67- 50.3), p=0.011] at OCT examinations. CONCLUSIONS NA observed by OCT 3-7 years after implantation was associated with subsequent worse clinical outcomes in both patient-based and stent-based analysis.

Mechanisms of gradual pressure drop in angiographically normal left anterior descending and right coronary artery: Insights from wave intensity analysis. J Cardiol 2021; 78:72-78. [PMID: 33509679 DOI: 10.1016/j.jjcc.2021.01.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 12/17/2020] [Accepted: 01/03/2021] [Indexed: 01/09/2023]
Abstract
BACKGROUND This study evaluated the mechanism of decline in coronary pressure from the proximal to the distal part of the coronary arteries in the left anterior descending (LAD) versus the right coronary artery (RCA) from the insight of coronary hemodynamics using wave intensity analysis (WIA). METHODS Twelve patients with angiographically normal LAD and RCA were prospectively enrolled. Distal coronary pressure, mean aortic pressure, and average peak velocity were measured at 4 different positions: 9, 6, 3, and 0 cm distal from each coronary ostium. RESULTS The distal-to-proximal coronary pressure ratio during maximum hyperemia gradually decreased in proportion to the distance from the ostium (0.92±0.03 and 0.98±0.03 at 9 cm distal to the LAD and RCA ostium). WIA showed the dominant forward-traveling compression wave gradually decreased and the backward-traveling suction wave gradually decreased in proportion to the decrease in coronary pressure through the length of the non-diseased LAD but not the RCA. CONCLUSIONS The pushing wave and suction wave intensities on WIA were diminished in proportion to the distance from the ostium of the LAD despite the wave intensity not changing across the length of the RCA, which may lead to gradual intracoronary pressure drop in the angiographically normal LAD.

Association of the Hemoglobin to Serum Creatinine Ratio with In-Hospital Adverse Outcomes after Percutaneous Coronary Intervention among Non-Dialysis Patients: Insights from a Japanese Nationwide Registry (J-PCI Registry). J Clin Med 2020; 9:jcm9113612. [PMID: 33182592 PMCID: PMC7696709 DOI: 10.3390/jcm9113612] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Revised: 10/31/2020] [Accepted: 11/06/2020] [Indexed: 12/17/2022] Open
Abstract
Although baseline hemoglobin and renal function are both important predictors of adverse outcomes after percutaneous coronary intervention (PCI), scarce data exist regarding the combined impact of these factors on outcomes. We sought to investigate the impact and threshold value of the hemoglobin to creatinine (Hgb/Cr) ratio, on in-hospital adverse outcomes among non-dialysis patients in a Japanese nationwide registry. We analyzed 157,978 non-dialysis patients who underwent PCI in 884 Japanese medical institutions in 2017. We studied differences in baseline characteristics and in-hospital clinical outcomes among four groups according to their quartiles of the Hgb/Cr ratios. Compared with patients with higher Hgb/Cr ratios, patients with lower ratios were older and had more comorbidities and complex coronary artery disease. Patients with lower hemoglobin and higher creatinine levels had a higher rate of in-hospital adverse outcomes including in-hospital mortality and procedural complications (defined as occurrence of cardiac tamponade, cardiogenic shock after PCI, emergency operation, or bleeding complications that required blood transfusion). On multivariate analyses, Hgb/Cr ratio was inversely associated with in-hospital mortality (odds ratio: 0.91, 95% confidence interval: 0.89–0.92; p < 0.001) and bleeding complications (odds ratio: 0.92, 95% confidence interval: 0.90–0.94; p < 0.001). Spline curve analysis demonstrated that these risks started to increase when the Hgb/Cr ratio was <15, and elevated exponentially when the ratio was <10. Hgb/Cr ratio is a simple index among non-dialysis patients and is inversely associated with in-hospital mortality and bleeding complications after PCI.

Feasibility of management of hemodynamically stable patients with acute myocardial infarction following primary percutaneous coronary intervention in the general ward settings. PLoS One 2020; 15:e0240364. [PMID: 33035270 PMCID: PMC7546471 DOI: 10.1371/journal.pone.0240364] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 09/24/2020] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Although current guidelines recommend admission to the intensive/coronary care unit (ICU/CCU) for patients with ST-segment elevation myocardial infarction (MI), routine use of the CCU in uncomplicated patients with acute MI remains controversial. We aimed to evaluate the safety of management in the general ward (GW) of hemodynamically stable patients with acute MI after primary percutaneous coronary intervention (PCI). METHODS Using a large nationwide administrative database, a cohort of 19426 patients diagnosed with acute MI in 52 hospitals where a CCU was available were retrospectively analyzed. Patients with mechanical cardiac support and Killip classification 4, and those without primary PCI on admission were excluded. A total of 5736 patients were included and divided into the CCU (n = 3488) and GW (n = 2248) groups according to the type of hospitalization room after primary PCI. Propensity score matching was performed, and 1644 pairs were matched. The primary endpoint was in-hospital mortality at 30 days. RESULTS The CCU group had a higher rate of Killip classification 3 and ambulance use than the GW group. There was no significant difference in the incidence of in-hospital mortality within 30 days among the matched subjects. Multivariable Cox proportional hazard model analysis among unmatched patients supported the findings (hazard ratio 1.12, 95% confidence interval 0.66-1.91, p = 0.67). CONCLUSIONS The use of the GW was not associated with higher in-hospital mortality in hemodynamically stable patients with acute MI after primary PCI. It may be feasible for the selected patients to be directly admitted to the GW after primary PCI.

Abstract
BACKGROUND With the rapid spread of COVID-19, hospitals providing percutaneous coronary intervention (PCI) were placed in unique and unfamiliar circumstances. This study evaluated variations in the treatment of coronary artery disease according to time course of the COVID-19 pandemic in Japan.Methods and Results:The Japanese Association of Cardiovascular Intervention and Therapeutics performed serial surveys during the pandemic (in mid-April, late-April and mid-May 2020) with queries regarding the implementation of PCI. Hospitals were asked about their treatment strategies for elective PCI and emergency PCI for ST-elevation myocardial infarction (STEMI) and high-risk acute coronary syndrome (ACS) patients. Most hospitals opted to perform primary PCI in the usual manner at the beginning of the pandemic. As the pandemic progressed, hospitals in the 7 populated areas downgraded the performance of PCI for chronic coronary syndrome and high-risk ACS, but not for STEMI patients. After the state of emergency was lifted in most prefectures in mid-May, the rate of PCI gradually normalized. Screening tests, such as polymerase chain reaction and chest computed tomography, in ACS were frequently used. CONCLUSIONS The COVID-19 pandemic greatly affected PCI treatment in Japan. However, even in the most critical situations during the pandemic, most institutions continued to perform primary PCI normally for STEMI patients.

Abstract
In most areas in Japan, patients with ST-elevation myocardial infarction (STEMI) would be transferred to the secondary hospitals or tertiary hospitals according to the judgement of emergency medical service (EMS) staff members. We hypothesized that in-hospital outcomes would be worse in STEMI patients judged as tertiary emergency than in those judged as secondary emergency, which may support the judgement of the current EMS systems. The purpose of this study was to compare in-hospital outcomes of STEMI between patients judged as secondary emergency and those judged as tertiary emergency. We included 238 STEMI patients who were transferred to our institution using EMS hotline, and divided those into the secondary emergency group (n = 106) and the tertiary emergency group (n = 132). The primary endpoint was in-hospital death. The prevalence of shock was significantly higher in the tertiary emergency group than in the secondary emergency group (32.6% vs. 10.4%, p < 0.001). The GRACE score was significantly higher in the tertiary emergency group than the secondary emergency group [146 (118–188) vs. 134 (101–155), p < 0.001]. The incidence of in-hospital death was significantly higher in the tertiary emergency group than in the secondary emergency group (8.0% vs. 2.1%, p = 0.014). The multivariate logistic regression analysis revealed that the tertiary emergency was significantly associated with in-hospital death (OR 3.52, 95% CI 1.24–10.02, p = 0.018) after controlling age and gender. In conclusion, the tertiary emergency was significantly associated with in-hospital death. Our results might validate the judgement of levels of emergency by local EMS staff members.
