Abstract Background Patients with leukaemia are at increased risk of cardiovascular events. There is limited outcomes data for patients with a history of leukaemia who present with an acute myocardial infarction (AMI). Purpose To examine the prevalence and clinical characteristics of patients with leukaemia presenting with AMI, and evaluate differences in clinical outcomes according to the subtype of leukaemia in comparison to patients without leukaemia. Methods We analysed the Nationwide Inpatient Sample (2004–2014) for patients with a primary discharge diagnosis of AMI and concomitant leukaemia, and further stratified according to the subtype of leukaemia into 4 groups; AML; ALL; CML; and CLL. Multiple logistic regression was conducted to identify the association between leukaemia and major acute cardiovascular and cerebrovascular events (MACCE; composite of mortality, stroke and cardiac complications) and bleeding. Results Out of 6,750,927 AMI admissions, a total of 21,694 patients had a leukaemia diagnosis. The leukaemia group experienced higher rates of MACCE (11.8% vs. 7.8%), mortality (10.3% vs. 5.8%) and bleeding (5.6% vs. 5.3%). Following adjustments, leukaemia was independently associated with increased odds of MACCE (OR 1.26 [1.20,1.31]) and mortality (OR 1.43 [1.37,1.50]) without an increased risk of bleeding (OR 0.86 [0.81,0.92]). Acute myeloid leukaemia (AML) was associated with approximately three-fold risk of MACCE (RR 2.81 [2.51, 3.13]) and a four-fold risk of mortality (RR 3.75 [3.34, 4.22]) (Figure 1). Patients with leukaemia were less likely to undergo coronary angiography (CA) (48.5% vs. 64.5%) and percutaneous coronary intervention (PCI) (28.2% vs. 42.9%) compared to those without leukaemia. Figure 1.Relative risk of adverse events Conclusion Patients with leukaemia, especially those with AML, are associated with poor clinical outcomes after AMI, and are less likely to receive CA and PCI compared to those without leukaemia. A multi-disciplinary approach between cardiologists and haematology oncologists may improve the outcomes of patients with leukaemia after AMI.

Abstract Smoking is one of the leading risk factors for cardiovascular diseases, including ischemic heart disease and hypertension. However, in acute myocardial infarction (AMI) patients, smoking has been associated with better clinical outcomes, a phenomenon termed the “smoker’s paradox.” Given the known detrimental effects of smoking on the cardiovascular system, it has been proposed that the beneficial effects of smoking on outcomes is due to age differences between smokers and non-smokers and is therefore a smoker’s pseudoparadox. The aim of this study was to evaluate the association between smoking status and clinical outcomes in ST-segment elevation (STEMI) and non-STEMI (NSTEMI) patients treated by percutaneous coronary intervention (PCI), using a national multi-ethnic Asian registry. In unadjusted analyses, current smokers had better clinical outcomes following STEMI and NSTEMI. However, after adjusting for age, the protective effect of smoking was lost, confirming a smoker’s pseudoparadox. Interestingly, although current smokers had increased risk for recurrent MI within 1 year after PCI in both STEMI and NSTEMI patients, there was no increase in mortality. In summary, we confirm the existence of a smoker’s pseudoparadox in a multi-ethnic Asian cohort of STEMI and NSTEMI patients and report increased risk of recurrent MI, but not mortality, in smokers.

Abstract Background Morphine analgesia may affect absorption of co-prescribed P2Y12 antagonists attenuating platelet inhibition. The impact of peri-procedural intravenous (IV) morphine administration on clinical outcomes in patients undergoing primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI) is not well defined. Purpose To conduct a systematic review and meta-analysis exploring clinical outcomes with peri-procedural IV morphine in patients undergoing PPCI for STEMI. Methods Analysis of the electronic databases MEDLINE, EMBASE, CENTRAL, Scopus, Web of Science and ClinicalTrials.gov for association of peri-PCI IV morphine use with myocardial infarction (MI) and mortality. Primary and secondary outcomes were in-hospital or 30-day MI and all-cause mortality respectively. Results Eleven studies (1 randomised controlled trial; 10 cohort studies) were included for systematic review. Five studies, including 3,748 patients were included in meta-analysis of the primary outcome. Of 3,748 patients, 2,239 were treated concurrently with ticagrelor, 1,256 treated with clopidogrel and 253 with prasugrel. As shown in the Figure, there was a trend towards increased risk of myocardial infarction with IV morphine (odds ratio 1.88; 95% CI 0.87–4.09, I2 0%). Across seven studies and 6585 patients, no increased risk of mortality at the same composite time endpoint was evident (odds ratio 0.70, 95% CI 0.40–1.23, I2 19%). Figure 1. MI in hospital or at 30 days Conclusion Based on current literature, evidence of an association between IV morphine and myocardial infarction in patients undergoing PPCI for STEMI is limited by observational methodology and conflicting results. There is no evidence of an association between intravenous peri-procedural morphine and mortality. Clinical trial evidence with strong documentation of adverse events data is required to demonstrate association or causality. Acknowledgement/Funding None

Abstract BackgroundWe sought to develop and validate a novel marker-based risk score to improve stroke prognostication in patients with myocardial infarction (MI) undergoing primary percutaneous coronary intervention (PCI).MethodsA retrospective study was conducted and internally validated a new biomarker-based risk score for the incidence of stroke in 4103 patients with MI undergoing primary PCI who were randomized into a derivation and a validation cohort. Predictive values of markers and clinical variables were evaluated using Cox regression models and least absolute shrinkage and selection operator regression. The most important variables were included in the score, with weight proportional to the model coefficients.ResultsSignificant predictors of the incidence of cerebrovascular events were age, history of atrial fibrillation, history of hypertension, Killip class, blood pressure group, target lesion involving branches, percutaneous transluminal coronary angioplasty, and thrombus aspiration. The models had good calibration and discrimination in derivation and internal validation. The areas under the curve (AUC) of the receiver operating characteristic (ROC) curve analysis for predicting cerebrovascular events were 0.773 and 0.766 for the derivation and validation cohorts, respectively, at 5-year follow-up. Survival ROC curves exported the best cut-off values and divided them into low-risk and high-risk groups using the R language. We conducted Kaplan–Meier survival analysis for the two groups. Both groups displayed significant difference in the derivation and validation cohorts (P=0.00003 and P=0.009, respectively). We compared the new prediction model to the CHADS-VASc score; the AUCs were 0.773 and 0.754, respectively.ConclusionThe prediction model was internally validated and calibrated in large cohorts of patients with MI receiving primary PCI therapy. This risk score incorporates allows re-evaluation of the risk of cerebrovascular events after undergoing primary PCI.

Introduction: ST-elevation myocardial infarction (STEMI) is a relatively common cause of mortality among patients. The effects of risk factors as predictors of mortality in patients has been shown in different studies. The present study was performed aiming to evaluate the association between a family history of premature coronary artery diseases (CADs) with clinical outcomes among patients treated with percutaneous coronary intervention (PCI) for STEMI. Methods: This descriptive-analytical study was conducted in Shahid Madani Hospital of Tabriz University of Medical Sciences, Tabriz, Iran, on 200 patients with STEMI with a PCI. 100 out of these 200 patients had a family history of premature CAD. Patients were followed up within 48 hours after PCI, as well as one year after admission, and the secondary outcomes including myocardial infarction (MI), heart failure, ventricular arrhythmias (VAs), pulmonary edema, and death were evaluated. Results: The mean age of the patients with positive and negative family history of premature CAD was 56.37 ± 8.20 and 61.72 ± 7.42 years, respectively. The mean age of the patients with a family history of a premature CAD was significantly lower than that of patients without a family history of a premature CAD (P = 0.001). There was no significant difference in the frequency of CAD risk factors, angiographic findings, and its complications, ST-segment resolution and frequency of secondary outcomes during 48 hours and one year after admission between the study groups (P > 0.050). Conclusion: The present study showed that a family history of premature CAD does not predict the clinical outcomes in patients treated with PCI for STEMI which should be validated across future studies.

ObjectiveThe comparative efficacy and safety of prasugrel and ticagrelor in patients with myocardial infarction (MI) treated with percutaneous coronary intervention (PCI) remain unclear. We aimed to investigate the association of treatment with clinical outcomes.MethodsIn the SWEDEHEART (Swedish Web-system for enhancement and development of evidence-based care in heart disease evaluated according to recommended therapies) registry, all patients with MI treated with PCI and discharged on prasugrel or ticagrelor from 2010 to 2016 were included. Outcomes were 1-year major adverse cardiac and cerebrovascular events (MACCE, death, MI or stroke), individual components and bleeding. Multivariable adjustment, inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were used to adjust for confounders.ResultsWe included 37 990 patients, 2073 in the prasugrel group and 35 917 in the ticagrelor group. Patients in the prasugrel group were younger, more often admitted with ST elevation MI and more likely to have diabetes. Six to twelve months after discharge, 20% of patients in each group discontinued the P2Y12 receptor inhibitor they received at discharge. The risk for MACCE did not significantly differ between prasugrel-treated and ticagrelor-treated patients (adjusted HR 1.03, 95% CI 0.86 to 1.24). We found no significant difference in the adjusted risk for death, recurrent MI or stroke alone between the two treatments. There was no significant difference in the risk for bleeding with prasugrel versus ticagrelor (2.5% vs 3.2%, adjusted HR 0.92, 95% CI 0.69 to 1.22). IPTW and PSM analyses confirmed the results.ConclusionIn patients with MI treated with PCI, prasugrel and ticagrelor were associated with similar efficacy and safety during 1-year follow-up.
