Abstract Background Previous studies showed prolonged patient and system delay in female patients with acute coronary syndromes (ACS) which is thought to be a major driver of discrepancies in their cardiovascular (CV) outcomes. Indeed, timely management is particularly important in patients with ST-segment elevation myocardial infarction (STEMI), as increased total ischemic time augments infarct size and relates to poor CV survival. However, contemporary evidence on sex-specific differences in ACS management and discrepancies in outcomes is limited and controversial. Purpose We sought to systematically investigate whether a sex-gap in symptom-to-door (STD), door-to-balloon (DTB)/door-to-PCI (DTP) time exists in a prospective ACS cohort and if such differences translate into different rates of major adverse cardiovascular events (MACE) at one year. Methods From 2009 to 2019, 4'930 ACS patients with a main diagnosis of NSTEMI (43.3%), STEMI (53.3%) or unstable angina (3.4%) were enrolled in the multicentre, prospective SPUM-ACS study of which 4'671 completed follow-up at one year. STD, DTB and DTP time was analyzed. The primary endpoint, a composite measure of all-cause death, nonfatal myocardial infarction, nonfatal stroke and ischemia-driven revascularization, was adjudicated by an independent clinical endpoint committee. Kaplan-Meier and multivariate-adjusted Cox proportional hazard regression models were used for time-to-event analyses. Results A total of 1'019 (20.7%) women and 3'911 (79.3%) men with a main diagnosis of ACS were included in the study. At presentation, women were older (69.6±12.0 vs. 62.2±12.1 years, P<0.001), more likely to have impaired renal function (median, 81.2 vs. 89.2 ml/min/1.73m2, P<0.001) and a history of hypertension (63.9% vs. 54.3%, P<0.001). STD time was significantly higher in female STEMI (median, 3.2 vs. 2.5 hours, P<0.001) and NSTEMI patients (median, 7.0 vs. 5.0 hours, P=0.015). Importantly, DTB time did not differ between sexes in STEMI patients (1.0 vs. 1.0 hour, P=0.430). Similarly, DTP time of female NSTEMI patients was comparable to males (4.3 vs. 4.4 hours, P=0.855). In the entire cohort, female ACS patients did not show a higher occurrence of the primary endpoint at one year (crude HR 0.86, 95% CI 0.72–1.04; adjusted HR 0.83, 95% CI, 0.66–1.05). In a multivariate-adjusted subgroup analysis, neither female STEMI (adjusted HR 0.82, 95% CI 0.59–1.15) nor NSTEMI patients (adjusted HR 0.87, 95% CI 0.61–1.24) showed higher hazards for the primary endpoint compared to male patients. Conclusions Women with a main diagnosis of STEMI show considerably higher prehospital delay, thus prolonged total ischemic time which is mainly driven by increased STD time. Intriguingly, this does not translate into higher rates of MACE compared to men at one year. Women with ACS may particularly benefit from measures aimed at reducing prehospital delay, as this may further improve long-term prognosis after the acute event.

Abstract   Background/Introduction; A rapid rule-out or rule-in protocol based on the 0-h/1-hour algorithm using high-sensitivity cardiac troponin T (hs-cTnT) is recommended by the European Society of Cardiology (ESC). Around 40–50% were stratified into “rule-out” group, and their 30-days prognosis was excellent. However, the one-year prognosis is uncertain. We aimed to better characterize these patients. Methods This study was a prospective, multi-center, observational study of patients with suspected non-ST elevation acute coronary syndrome (NSTE-ACS) admitted to 5 hospitals in Japan and Taiwan from 2014 November to 2018 December, respectively. All patients underwent a clinical assessment the included medical history, physical examination, 12-lead ECG, standard blood test, chest radiography. Exclusion criteria were ST elevated myocardial infarction, chronic kidney disease (serum creatinine more than 3 mg/dL) and congestive heart failure, arrhythmia, or infection disease. The patients were divided into three groups according to the algorithm; “rule-out”, “observe” and “rule-in”. The final diagnosis was then adjudicated by 2 independent cardiologists using all available information, including coronary angiography, coronary computed tomography, stress electrocardiography and follow-up data. The presence of acute myocardial infarction (AMI) was defined according to the Fourth Universal Definition of Myocardial Infarction. After hospital discharge patients were follow after one-year b telephone or in written form. Major adverse cardiovascular events (including death myocardial infarction, coronary artery bypass grafting, percutaneous coronary intervention (PCI)) were recorded by establishing contact with the patient and the family physicians. The primary prognosis end point was all-cause mortality. Results Of the 1,187 patients were analyzed after exclusion. The prevalence rate of AMI was 16.1%. According to the algorithm, 42% (n=493) of patients were assigned to “rule-out” group and had no AMI nor death. The most common final adjudicated diagnoses were atypical chest pain (80%), gallstone attack (3%) and vasospastic angina pectoris (2%). All patients with unstable angina (4.7%) underwent PCI. Conclusion(s) Our findings suggest that the “rule-out” group patients according to ESC 0-h/1-hour algorithm provides very high safety and efficacy for the triage toward AMI.

Abstract Objectives The aim of this study was to assess the safety and efficacy of ticagrelor versus prasugrel for patients with acute coronary syndrome (ACS) according to their glomerular filtration rate (GFR). Background The outcomes of ticagrelor versus prasugrel in patients with ACS according to GFR have not been defined. Methods Patients (n=3985) with GFR available were categorized in three groups according to the tertiles of GFR. The primary endpoint was a composite of all-cause death, myocardial infarction and stroke at 1 year. Results The primary endpoint occurred significantly more often in patients with low GFR compared to high GFR as well as in patients with low GFR compared to intermediate GFR (picture 1). Patients in the lowest GFR group had significantly higher ischemic and bleeding risks than patients in the intermediate (hazard ratio [HR] 1.93 and 1.68) or high GFR groups (HR 3.52 and 2.96). In the group with low GFR, the primary endpoint occurred in 103 of 677 ticagrelor patients (15.4%) and in 72 of 652 prasugrel patients (11.2%; (HR=1.45, [1.07–1.96], p=.016, picture 2). In addition, each single component of the primary endpoint and stent thrombosis were numerically lower with prasugrel compared with ticagrelor. Occurrence of myocardial infarction was 3.7% with prasugrel compared to 6.6% with ticagrelor (p=0.019). BARC 3–5 bleeding events were similar with ticagrelor and prasugrel (8.8% versus 7.1%, p=0.278). In the intermediate and high GFR group the primary endpoint and bleeding events were similar between prasugrel and ticagrelor. Conclusions The incidence of a composite endpoint (all-cause death, myocardial infarction or stroke) occurred less frequently in patients who received prasugrel compared to patients who received ticagrelor in the low GFR population, whereas rate of bleeding events was similar.

Abstract Introduction The myocardial-ischemic-injury-index (MI3) is a promising machine learned algorithm that predicts the likelihood of myocardial infarction in patients with suspected acute coronary syndrome. Whether this algorithm performs well in unselected patients or predicts recurrent events is unknown. Methods In an observational analysis from a multi-centre randomised trial, we included all patients with suspected acute coronary syndrome and serial high-sensitivity cardiac troponin I measurements without ST-segment elevation myocardial infarction. Using gradient boosting, MI3 incorporates age, sex, and two troponin measurements to compute a value (0–100) reflecting an individual's likelihood of myocardial infarction, and estimates the negative predictive value (NPV) and positive predictive value (PPV). Model performance for an index diagnosis of myocardial infarction, and for subsequent myocardial infarction or cardiovascular death at one year was determined using previously defined low- and high-probability thresholds (1.6 and 49.7, respectively). Results In total 20,761 of 48,282 (43%) patients (64±16 years, 46% women) were eligible of whom 3,278 (15.8%) had myocardial infarction. MI3 was well discriminated with an area under the receiver-operating-characteristic curve of 0.949 (95% confidence interval 0.946–0.952) identifying 12,983 (62.5%) patients as low-probability (sensitivity 99.3% [99.0–99.6%], NPV 99.8% [99.8–99.9%]), and 2,961 (14.3%) as high-probability (specificity 95.0% [94.7–95.3%], PPV 70.4% [69–71.9%]). At one year, subsequent myocardial infarction or cardiovascular death occurred more often in high-probability compared to low-probability patients (17.6% [520/2,961] versus 1.5% [197/12,983], P<0.001). Conclusions In unselected consecutive patients with suspected acute coronary syndrome, the MI3 algorithm accurately estimates the likelihood of myocardial infarction and predicts probability of subsequent adverse cardiovascular events.

We assessed the prognostic value of serum levels of endocan in patients with the acute coronary syndrome (ACS) through its correlation with the Thrombolysis in Myocardial Infarction (TIMI) risk score and compared the possible association with clinical outcomes. In this prospective cross-sectional study, we enrolled 320 patients with documented ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), or unstable angina (UA) who underwent diagnostic coronary angiography. Endocan was measured soon after admission in the emergency department. In-hospital death, heart failure, and recurrent infarction were considered major adverse cardiac events (MACEs). There was a significant positive correlation between endocan level and TIMI risk score and MACE. The optimal cutoff values of endocan to predict clinical end points were 3.45 ng/mL in patients with STEMI and 2.85 ng/mL in patients with UA/NSTEMI. Multivariate logistic regression analysis indicated that endocan independently correlated with MACE. Moreover, cardiac troponin I, creatine kinase-MB, and circulating endocan were found to be independently associated with MACE in patients with ACS. In conclusion, a high endocan level on hospital admission is an independent predictor of worse cardiovascular outcomes and higher TIMI risk score in patients with ACS.

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

Purpose. Determination of clinical and instrumental predictors of progressive course of multifocal atherosclerosis (MFA) in patients one year after myocardial infarction (MI), initially having hemodynamically insignificant stenoses of carotid arteries.Materials and methods. From database of patients with acute coronary syndrome treated in the Kemerovo Regional Clinical Cardiac Dispensary in 2009–2010 we selected for this study 141 patients with verified diagnosis of MI and hemodynamically insignificant lesions in the internal carotid artery (ICA) (stenosis up ≤ 55 %). All patients had coronary atherosclerosis verified on coronary angiography at admission because of MI. A multivariate analysis of possible predictors of the progressive course of multifocal atherosclerosis was made based on assessment of the development of cardiovascular complications (CVC) (death, MI, stroke and transient cerebral circulatory attacks [TIA]), as well as revascularizations and negative dynamics of parameters of color duplex scanning (CDS) of ICA during one year after MI. Results. One year after MI the overall incidence of CVC was 16.3 % (n=23). Structure of registered events was as follows: death from MI 7.1 % (n=10), deaths from stroke 2.1 % (n=3) and other causes 2.1 % (n=3), non-fatal MI 5.0 % (n=7), non-fatal stroke / TIA 2.1 % (n=3), carotid revascularization 2.8 % (n=4), coronary revascularization 14.9 % (n=21). CDC of ICAs was repeated in 125 patients. There were 17 (13.6 %) cases of progression of carotid atherosclerosis in the form of de novo bilateral stenoses in 14 (11.2 %) patients, stenoses in the left and right ICA 1 patient and 2 patients, respectively. The following predictors of progression of atherosclerosis of cerebral arteries were identified: family history of cardiovascular diseases (CVD),ICA stenosis ≥45 %, baseline circular atherosclerotic plaque (ASP). Predictors of high risk of stroke were family history of CVD, history of stroke,ICA stenosis ≥45 %, heterogeneous hypoechoic ASP. As predictors of lethal outcome, we identified history of MI, high functional class of angina preceding the index MI, severe coronary vascular bed involvement (SYNTAX score >23), presence of any bilateral atherosclerotic lesion in ICAs, and heterogeneous hypoechoic ASP. Assessment of the contribution of adherence to therapy in the prognosis 1 year after hospital discharge was fulfilled in 125 alive patients. It allowed to conclude that patients with progression of atherosclerosis and nonfatal CVC were characterized by insufficient adherence to standard therapy.Conclusion. Predictors of the progressive course of multifocal atherosclerosis during one year after MI were identified in this study. It is necessary to strengthen therapeutic and preventive measures aimed at minimization of the impact of these factors in this category of patients.

Introduction: ST-segment elevation myocardial infarction (STEMI) in patients with concomitant multivessel coronary artery disease (CAD) is associated with poor prognosis. Hypothesis: We sought to determine the merits of percutaneous coronary intervention (PCI) of the culprit-only compared with a complete revascularization approach. Methods: The MEDLINE (PubMed, Ovid), Embase, Clinicaltrials.org and Cochrane databases were queried with various combinations of medical subject headings (MeSH) to identify articles comparing complete and culprit-only revascularization. Data were compared using a random-effect model to calculate unadjusted odds ratio. Results: A total of 26 studies consisting of 26,892 patients, 18,377 in the culprit-only and 8,515 in the complete revascularization group were included. The mean age of patients included in the study was 63 years, comprising 72% of male patients. Baseline characteristics of the two treatment groups were comparable. On a median follow-up of 1-year, culprit-only revascularization was associated with a significantly higher odds of major adverse cardiovascular events (MACE) (OR 1.36, 95% CI 1.10-1.69, p=0.005) (figure), angina (OR 2.28, 95% CI 1.83-2.85, p=<0.00001) and revascularization (OR 1.71, 95% CI 1.18- 2.49, p=0.005) compared to complete revascularization group. The all-cause mortality (OR 1.17, 95% CI 0.89-1.54, p=0.25),, cardiovascular mortality (OR 1.20, 95% CI 0.90-1.61, p=0.22), rate of heart failure (OR 1.17, 95% CI 0.86-1.59, p=0.31), CABG (OR 1.47, 95% CI 0.82-2.64, p=0.19), repeat MI (OR 1.23, 95% CI 0.92-1.63, p=0.17) and stroke (OR 1.27 95% CI 0.68-2.34, p=0.45%) were similar between the two groups. Conclusions: In contrast to the culprit-only approach, complete revascularization in patients with the acute coronary syndrome is associated with a significant reduction in MACE, angina and need for revascularization.

Background: Ischemic time has prognostic importance in ST-elevation myocardial infarction patients. Mobile intensive care unit use can reduce components of total ischemic time by appropriate triage of ST-elevation myocardial infarction patients. Methods: Data from the Acute Coronary Survey in Israel registry 2000–2010 were analyzed to evaluate factors associated with mobile intensive care unit use and its impact on total ischemic time and patient outcomes. Results: The study comprised 5474 ST-elevation myocardial infarction patients enrolled in the Acute Coronary Survey in Israel registry, of whom 46% ( n=2538) arrived via mobile intensive care units. There was a significant increase in rates of mobile intensive care unit utilization from 36% in 2000 to over 50% in 2010 ( p<0.001). Independent predictors of mobile intensive care unit use were Killip>1 (odds ratio=1.32, p<0.001), the presence of cardiac arrest (odds ratio=1.44, p=0.02), and a systolic blood pressure <100 mm Hg (odds ratio=2.01, p<0.001) at presentation. Patients arriving via mobile intensive care units benefitted from increased rates of primary reperfusion therapy (odds ratio=1.58, p<0.001). Among ST-elevation myocardial infarction patients undergoing primary reperfusion, those arriving by mobile intensive care unit benefitted from shorter median total ischemic time compared with non-mobile intensive care unit patients (175 (interquartile range 120–262) vs 195 (interquartile range 130–333) min, respectively ( p<0.001)). Upon a multivariate analysis, mobile intensive care unit use was the most important predictor in achieving door-to-balloon time <90 min (odds ratio=2.56, p<0.001) and door-to-needle time <30 min (odds ratio=2.96, p<0.001). One-year mortality rates were 10.7% in both groups (log-rank p-value=0.98), however inverse propensity weight model, adjusted for significant differences between both groups, revealed a significant reduction in one-year mortality in favor of the mobile intensive care unit group (odds ratio=0.79, 95% confidence interval (0.66–0.94), p=0.01). Conclusions: Among patients with ST-elevation myocardial infarction, the utilization of mobile intensive care units is associated with increased rates of primary reperfusion, a reduction in the time interval to reperfusion, and a reduction in one-year adjusted mortality.

Background: The prevalence and outcome of patients with cancer that experience acute coronary syndrome (ACS) have to be determined. Methods and results: The BleeMACS project is a multicentre observational registry enrolling patients with acute coronary syndrome undergoing percutaneous coronary intervention worldwide in 15 hospitals. The primary endpoint was a composite event of death and re-infarction after one year of follow-up. Bleedings were the secondary endpoint. 15,401 patients were enrolled, 926 (6.4%) in the cancer group and 14,475 (93.6%) in the group of patients without cancer. Patients with cancer were older (70.8±10.3 vs. 62.8±12.1 years, P<0.001) with more severe comorbidities and presented more frequently with non-ST-segment elevation myocardial infarction compared with patients without cancer. After one year, patients with cancer more often experienced the composite endpoint (15.2% vs. 5.3%, P<0.001) and bleedings (6.5% vs. 3%, P<0.001). At multiple regression analysis the presence of cancer was the strongest independent predictor for the primary endpoint (hazard ratio (HR) 2.1, 1.8–2.5, P<0.001) and bleedings (HR 1.5, 1.1–2.1, P=0.015). Despite patients with cancer generally being undertreated, beta-blockers (relative risk (RR) 0.6, 0.4–0.9, P=0.05), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (RR 0.5, 0.3–0.8, P=0.02), statins (RR 0.3, 0.2–0.5, P<0.001) and dual antiplatelet therapy (RR 0.5, 0.3–0.9, P=0.05) were shown to be protective factors, while proton pump inhibitors (RR 1, 0.6–1.5, P=0.9) were neutral. Conclusion: Cancer has a non-negligible prevalence in patients with acute coronary syndrome undergoing percutaneous coronary intervention, with a major risk of cardiovascular events and bleedings. Moreover, these patients are often undertreated from clinical despite medical therapy seems to be protective. Registration:The BleeMACS project (NCT02466854).
