Prior Stroke

Background: We sought to evaluate the impact of prior cerebrovascular and/or peripheral arterial disease (PAD) on in-hospital outcomes in patients with acute coronary syndromes. Methods: From 1 October 2010 to 26 February 2016, 13,904 acute coronary syndrome patients were enrolled in a national multicentre registry. They were divided into four groups: prior stroke/transient ischaemic attack (stroke/TIA); prior PAD; prior stroke/TIA and PAD; none. The endpoints included in-hospital mortality and a composite endpoint of death, re-infarction and stroke during hospitalization. Results: 6.3% patients had prior stroke/TIA, 4.2% prior PAD and 1.4% prior stroke/TIA and PAD. Prior stroke/TIA and/or PAD patients were less likely to receive evidence-based medical therapies (dual antiplatelet therapy: stroke/TIA= 88.6%, PAD= 86.6%, stroke/TIA+PAD= 85.7%, none= 92.2%, p<0.001; β-blockers: stroke/TIA= 77.1%, PAD= 72.1%, stroke/TIA+PAD= 71.9%, none= 80.8%, p<0.001; angiotensin-converting enzyme inhibitors/angiotensin receptor blockers: stroke/TIA= 86.3%, PAD= 83.6%, stroke/TIA+PAD= 83.2%, none= 87.1%, p=0.030) and to undergo percutaneous revascularization (stroke/TIA= 52.8%, PAD= 45.6%, stroke/TIA+PAD= 43.7%, none= 67.9%, p<0.001), despite more extensive coronary artery disease (three-vessel disease: stroke/TIA= 29.1%, PAD= 38.3%, stroke/TIA+PAD= 38.3%, none= 20.2%, p<0.001). In a multivariable analysis, prior stroke/TIA+PAD was a predictor of in-hospital mortality (odds ratio= 2.828, 95% confidence interval 1.001–7.990) and prior stroke/TIA (odds ratio= 1.529, 95% confidence interval 1.056–2.211), prior PAD (odds ratio= 1.618, 95% confidence interval 1.034–2.533) and both conditions (odds ratio= 3.736, 95% confidence interval 2.002–6.974) were associated with the composite endpoint. Conclusion: A prior history of stroke/TIA and/or PAD was associated with lower use of medical therapy and coronary revascularization and with worst short-term prognosis. An individualized management may improve their poor prognosis.

The Impact

Although revascularisation in non-ST-segment elevation acute coronary syndrome (NSTEACS) is associated with better outcomes, its impact in older adult patients is unclear. This is a retrospective analyses of three national NSTEACS registries conducted during the past decade in Spain. Patients aged 75 years and older were included: DESCARTES (DES; year 2002; n=534), MASCARA (MAS; 2005; n=1736) and DIOCLES (DIO; 2012; n=593). The adjusted association between revascularisation and total (inhospital and 6-month) mortality was estimated by two-stage meta-analysis (pooled effect across the three registries with inverse-variability weights) and one-stage meta-analysis (multilevel model with random effects across studies). The impact of revascularisation was assessed comparing the observed and the expected mortality based on a logistic regression model in the pooled database. Although revascularisation was associated with a lower risk of mortality in meta-analyses (two-stage: odds ratio 0.44, 95% confidence interval 0.29–0.67; one-stage: odds ratio 0.54, 95% confidence interval 0.36–0.81) and the revascularisation rate increased steadily from 2002 (DES 14.2%) to 2012 (DIO 43.7%), its impact was not patent across registries, probably because this increase was concentrated in low and medium-risk GRACE strata (tertile 1, 2 and 3: MAS 59%, 20% and 6%; DIO 64%, 39% and 19%, respectively). In conclusion, a consistent increase of revascularisation in NSTEACS in older adults was not followed by a decrease in mortality at 6 months, probably because the impact of this strategy is limited to the higher risk population, the stratum with the lowest revascularisation rate in real life.

Abstract Introduction Peripheral artery disease (PAD) is associated with heightened ischemic and bleeding risk in patients with acute coronary syndrome (ACS). With this study from real-life patients, we try to analyze the balance between ischemic and bleeding risk during treatment with dual antiplatelet therapy (DAPT) after an ACS according to the presence or not of PAD. Methods The data analyzed in this study were obtained from the fusion of 3 clinical registries of ACS patients: BleeMACS (2004–2013), CardioCHUVI/ARRITXACA (2010–2016) and RENAMI (2013–2016). All 3 registries include consecutive patients discharged after an ACS with DAPT and undergoing PCI. The merged data set contain 26,076 patients. A propensity-matched analysis was performed to match the baseline characteristics of patients with and without PAD. The impact of prior PAD in the ischemic and bleeding risk was assessed by a competitive risk analysis, using a Fine and Gray regression model, with death being the competitive event. For ischemic risk we have considered a new acute myocardial infarction (AMI), whereas for bleeding risk we have considered major bleeding (MB) defined as bleeding requiring hospital admission. Follow-up time was censored by DAPT suspension/withdrawal. Results From the 26,076 ACS patients, 1,600 have PAD (6.1%). Patients with PAD were older, and with more cardiovascular risk factors. DAPT with prasugrel/ticagrelor was less frequently prescribed in patients with PAD in comparison with the rest of the population (8.2% vs 22.8%, p<0.001). During a mean follow-up of 12.2±4.8 months, 964 patients died (3.7%), and 640 AMI (2.5%) and 685 MB (2.6%) were reported. After propensity-score matching, we obtained two matched groups of 1,591 patients. Patients with PAD showed a significant higher risk of both AMI (sHR 2.17, 95% CI 1.51–3.10, p<0.001) and MB (sHR 1.51, 95% CI 1.07–2.12, p=0.018), in comparison with those without PAD. The cumulative incidence of AMI was 63.9 and 29.8 per 1,000 patients/year in patients with and without PAD, respectively. The cumulative incidence of MB was 55.9 and 37.6 per 1,000 patients/year in patients with and without PAD, respectively. The rate difference per 1,000 patient-years for AMI between patients with and without PAD was +34.1 (95% CI 30.1–38.1), and for MB +18.3 (16.1–20.4). The net balance between ischemic and bleeding events comparing patients with and without PAD was positive (+15.8 per 1,000 patients/year, 95% CI 9.7–22.0). Conclusions PAD was associated with higher ischemic and bleeding risk after hospital discharge for ACS treated with DAPT. However, the balance between ischemic and bleeding risk was positive for patients with PAD in comparison with patients without PAD. As summary, ACS patients with PAD had an ischemic risk greater than the bleeding risk.

Abstract Background/Introduction Major disparities between women and men in the diagnosis, management and outcome of acute coronary syndrome are well recognised. Whether sex-specific diagnostic thresholds for myocardial infarction will address these differences is uncertain. Purpose To evaluate the impact of implementing a high-sensitivity cardiac troponin I (hs-cTnI) assay with sex-specific diagnostic thresholds for myocardial infarction in women and men with suspected acute coronary syndrome. Methods In a stepped-wedge, cluster-randomized controlled trial across ten hospitals we evaluated the implementation of a hs-cTnI assay in 48,282 (47% women) consecutive patients with suspected acute coronary syndrome. During a validation phase the hs-cTnI assay results were suppressed and a contemporary cTnI assay with a single threshold was used to guide care. Myocardial injury was defined as any hs-cTnI concentration >99th centile of 16 ng/L in women and 34 ng/L in men. The primary outcome was myocardial infarction after the initial presentation or cardiovascular death at 1 year. In this prespecified analysis, we evaluated outcomes in men and women before and after implementation of the hs-cTnI assay. Results Use of the hs-cTnI assay with sex-specific thresholds increased myocardial injury in women by 42% (from 3,521 (16%) to 4,991 (22%)) and by 6% in men (from 5,068 (20%) to 5,369 (21%)). Whilst treatment increased in both sexes, women with myocardial injury remained less likely than men to undergo coronary revascularisation (15% versus34%), or to receive dual anti-platelet (26% versus43%), statin (16% versus26%) or other preventative therapies (P<0.001 for all). The primary outcome occurred in 18% (369/2,072) and 17% (488/2,919) of women with myocardial injury during the validation and implementation phase respectively (adjusted hazard ratio 1.11, 95% confidence interval 0.92 to 1.33), compared to 18% (370/2,044) and 15% (513/3,325) of men (adjusted hazard ratio 0.85, 95% confidence interval 0.71 to 1.01). Patient management Conclusion Use of sex-specific thresholds identified five-times more additional women than men with myocardial injury, such that the proportion of women and men with myocardial injury is now similar. Despite this increase, women received approximately half the number of treatments for coronary artery disease as men and their outcomes were not improved.

Background: Stroke is a rare but serious complication of acute coronary syndrome. At present, no specific score exists to identify patients at higher risk. The aim of the present study is to test whether each clinical variable included in the CHA2DS2-VASc score retains its predictive value in patients with recent acute coronary syndrome, irrespective of atrial fibrillation. Methods: The meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. All clinical trials and observational studies presenting data on the association between stroke/transient ischemic attack incidence and at least one CHA2DS2-VASc item in patients with a recent acute coronary syndrome were considered in the analysis. Atrial fibrillation diagnosis was also considered. Results: The whole cohort included 558,193 patients of which 7108 (1.3%) had an acute stroke and/or transient ischemic attack during follow-up (median nine months; 1st–3rd quartile 1–12 months). Age and previous stroke had the highest odds ratios (odds ratio 2.60; 95% confidence interval 2.21–3.06 and odds ratio 2.74; 95% confidence interval 2.19–3.42 respectively), in accordance with the two-point value given in the CHA2DS2-VASc score. All other factors were positively associated with stroke, although with lower odds ratios. Atrial fibrillation, while present in only 11.2% of the population, confirmed its association with an increased risk of stroke and/or transient ischemic attack (odds ratio 2.04; 95% confidence interval 1.71–2.44). Conclusions: All risk factors included in the CHA2DS2-VASc score are associated with stroke/ transient ischemic attack in patients with recent acute coronary syndrome, and retain similar odds ratios to what already seen in atrial fibrillation. The utility of CHA2DS2-VASc score for risk stratification of stroke in patients with acute coronary syndrome remains to be determined.

Objective This study was performed to investigate the association of the admission hemoglobin level with the incidence of in-hospital cardiac arrest (IHCA) in patients with acute coronary syndrome (ACS) complicated by cardiogenic shock (CS). Methods In this retrospective study, we reviewed the medical records of consecutive patients with ACS complicated by CS admitted to the coronary care unit from January 2014 to October 2017. Logistic regression models were carried out to evaluate the association between hemoglobin and the incidence of IHCA. Interaction and subgroup analyses were also performed. Results In total, 211 patients were included in the study, and 61 (28.9%) patients developed IHCA. In the multivariable analysis, hemoglobin was a strong independent predictor of IHCA (odds ratio, 0.971; 95% confidence interval, 0.954–0.989). In the fully adjusted model, patients in the higher hemoglobin tertile were less likely to develop IHCA than patients in the lowest hemoglobin tertile (odds ratio, 0.194; 95% confidence interval, 0.071–0.530). The relationship remained stable in most subgroups except patients aged ≥70 years. Conclusion In patients with ACS complicated by CS, the incidence of IHCA is related to the hemoglobin concentration, and a high hemoglobin concentration is a protective factor against the development of IHCA.

The clinical significance of non-obstructive coronary artery disease is the subject of debate. Our objective was to evaluate the long-term cardiovascular prognosis associated with non-obstructive coronary artery disease in patients undergoing coronary angiography, and to conduct a stratification by sex, diabetes, and clinical indication. We designed a multi-centre retrospective longitudinal observational study of 3265 patients that were classified into three groups: normal coronary arteries (lesion <20%, 1426 patients), non-obstructive coronary artery disease (20–50%, 643 patients), and obstructive coronary artery disease (>70%, 1196 patients). During a mean follow-up of 43 months, we evaluated a combined cardiovascular event: acute myocardial infarction, stroke, hospitalization for heart failure, or cardiovascular death. Multivariable-adjusted Cox proportional hazard models showed a worse prognosis in patients with non-obstructive coronary artery disease, in comparison with patients of normal coronary arteries group, in the total population (hazard ratio 1.72, 95% confidence interval 1.23–2.39; p for trend <0.001), in non-diabetics (hazard ratio 2.12, 95% confidence interval: 1.40–3.22), in women (hazard ratio 1.75, 95% confidence interval 1.10–2.77), and after acute coronary syndrome (hazard ratio 2.07, 95% confidence interval 1.25–3.44). In conclusion, non-obstructive coronary artery disease is associated with an impaired long-term cardiovascular prognosis. This association held for non-diabetics, women, and after acute coronary syndrome.

BackgroundLarge-scale real-world data to evaluate the impact of chest pain centre (CPC) accreditation on acute coronary syndrome (ACS) emergency care in heavy-burden developing countries like China are rare.MethodsThis study is a retrospective study based on data from the Hospital Quality Monitoring System (HQMS) database. This study included emergency patients admitted with ACS to hospitals that uploaded clinical data continuously to the database from 2013 to 2016. Propensity score matching was used to compare hospitals with and without CPC accreditation during this period. A longitudinal self-contrast comparison design with mixed-effects models was used to compare management of ACS before and after accreditation.ResultsA total of 798 008 patients with ACS from 746 hospitals were included in the analysis. After matching admission date, hospital levels and types and adjusting for possible covariates, patients with ACS admitted to accredited CPCs had lower in-hospital mortality (OR=0.70, 95% CI 0.53 to 0.93), shorter length of stay (LOS; adjusted multiplicative effect=0.89, 95% CI 0.84 to 0.94) and more percutaneous coronary intervention (PCI) procedures (OR=3.53, 95% CI 2.20 to 5.66) than patients admitted in hospitals without applying for CPC accreditation. Furthermore, when compared with the ‘before accreditation’ group only in accredited CPCs, the in-hospital mortality and LOS decreased and the usage of PCI were increased in both ‘accreditation’ (for in-hospital mortality: OR=0.86, 95% CI 0.79 to 0.93; for LOS: 0.94, 95% CI 0.93 to 0.95; for PCI: OR=1.22, 95% CI 1.18 to 1.26) and ‘after accreditation’ groups (for in-hospital mortality: OR=0.90, 95% CI 0.84 to 0.97; for LOS: 0.89, 95% CI 0.89 to 0.90; for PCI: OR=1.36, 95% CI 1.33 to 1.39). The significant benefits of decreased in-hospital mortality, reduced LOS and increased PCI usage were also observed for patients with acute myocardial infarction.ConclusionsCPC accreditation is associated with better management and in-hospital clinical outcomes of patients with ACS. CPC establishment and accreditation should be promoted and implemented in countries with high levels of ACS.

Baseline Demographic

Background: Out-of-hospital cardiac arrest (OHCA) is a major cause of death worldwide. Recent guidelines recommend the centralisation of OHCA services in cardiac arrest centres to improve outcomes. In 2015, two major tertiary cardiac centres in London merged to form a large dedicated tertiary cardiac centre. This study aimed to compare the short-term mortality of patients admitted with an OHCA before-and-after the merger of services had taken place and admission criteria were relaxed, which led to managing OHCA in higher volume. Methods: We retrospectively analysed the data of OHCA patients pre- and post-merger. Baseline demographic and medical characteristics were recorded, along with factors relating to the cardiac arrest. The primary endpoint was in-hospital mortality. Results: OHCA patients ( N =728; 267 pre- and 461 post-merger) between 2013 and 2018 were analysed. Patients admitted pre-merger were older (65.0 vs. 62.4 years, p=0.027), otherwise there were similar baseline demographic and peri-arrest characteristics. There was a greater proportion of non-acute coronary syndrome-related OHCA admission post-merger (10.1% vs. 23.4%, p=0.0001) and a corresponding decrease in those admitted with ST-elevation myocardial infarction (80.2% vs. 57.0%, p=0.0001) and those treated with percutaneous coronary intervention (78.8% vs. 54.0%, p=0.0001). Despite this, in-hospital mortality was lower post-merger (63.7% vs. 44.3%, p=0.0001), which persisted after adjustment for demographic and arrest-related characteristics using stepwise logistic regression ( p=0.036) between the groups. Conclusion: Despite an increase in non-acute coronary syndrome-related OHCA cases, the formation of a centralised invasive heart centre was associated with improved survival in OHCA patients. This suggests there may be a benefit of a cardiac arrest centre model of care.
