IMPACT OF ANEMIA ON CLINICAL OUTCOME IN PATIENTS WITH ATRIAL FIBRILLATION UNDERGOING PERCUTANEOUS CORONARY INTERVENTION: INSIGHTS FROM THE AFCAS REGISTRY

OBJECTIVES: Anaemia has an adverse impact on the outcome in the general patient population undergoing percutaneous coronary intervention (PCI). The aim of this study was to analyse the impact of anaemia on the 12-month clinical outcome of patients with atrial fibrillation (AF) undergoing PCI and therefore requiring intense antithrombotic treatment. We hypothesised that anaemia might be associated with a worse outcome and more bleeding in these anticoagulated patients. SETTING: Data were collected from 17 secondary care centres in Europe. PARTICIPANTS: Consecutive patients with AF undergoing PCI were enrolled in the prospective, multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry. Altogether, 929 patients participated in the study. Preprocedural haemoglobin concentration was available for 861 (92.7%; 30% women). The only exclusion criteria were inability or unwillingness to give informed consent. Anaemia was defined as a haemoglobin concentration of <12 g/dL for women and <13 g/dL for men. OUTCOME MEASURES: The primary endpoint was occurrence of major adverse cardiac and cerebrovascular events (MACCE) or bleeding events. RESULTS: 258/861 (30%) patients had anaemia. Anaemic patients were older, more often had diabetes, higher CHA(2)DS(2)-VASc scores, prior history of heart failure, chronic renal impairment and acute coronary syndrome. Anaemic patients had more MACCE than non-anaemic (29.1% vs 19.4%, respectively, p=0.002), and minor bleeding events (7.0% vs 3.3%, respectively, p=0.028), with a trend towards more total bleeding events (25.2% vs 21.7%, respectively, p=0.059). No difference was observed in antithrombotic regimens at discharge. In multivariate analysis, anaemia was an independent predictor of all-cause mortality at 12-month follow-up (hazard ratio 1.62, 95% CI 1.05 to 2.51, p=0.029). CONCLUSIONS: Anaemia was a frequent finding in patients with AF referred for PCI. Anaemic patients had a higher all-cause mortality, more thrombotic events and minor bleeding events. Anaemia seems to be an identification of patients at risk for cardiovascular events and death. TRIAL REGISTRATION: ClinicalTrials.gov number NCT00596570

Further evaluation of plasma sphingomyelin levels as a risk factor for coronary artery disease

BACKGROUND: Sphingomyelin (SM) is the major phospholipid in cell membranes and in lipoproteins. In human plasma, SM is mainly found in atherogenic lipoproteins; thus, high levels of SM may promote atherogenesis. METHODS: We investigated in a median follow up of 6.0 years the association of SM with the incidence of a combined endpoint (myocardial infarction and cardiovascular death) in stable and unstable patients, and its relation to other marker of atherosclerosis in 1,102 patients with angiographically documented CAD and 444 healthy controls. RESULTS AND DISCUSSION: Logistic regression analysis showed that SM categorized by median was associated with an elevated risk for CAD (HR 3.2, 95%CI 2.5–4.0, p < 0.05). SM levels were correlated with apoB (r = 0.34) and triglyceride levels (r = 0.31). In patients with stable angina (n = 614), SM categorized by median was not related to incidence of a combined endpoint (cardiovascular death and myocardial infarction) (p = 0.844 by Log-rank test). However, in patients with acute coronary syndrome (n = 488), elevated SM was related to the combined endpoint (p < 0.05 by Log-rank test), also in a multivariate Cox regression analysis including potential confounders (HR 1.8, 95%CI 1.0–3.3, p < 0.05). CONCLUSION: The results of our study reveal that 1) human plasma SM levels are a risk factor for CAD; 2) the pro-atherogenic property of plasma SM might be related to metabolism of apoB-containing or triglyceride-rich lipoproteins; and 3) plasma SM levels are a predictor for outcome of patients with acute coronary syndrome

Incremental value of high-sensitive troponin T in addition to the revised cardiac index for peri-operative risk stratification in non-cardiac surgery

Aims We aimed to evaluate the incremental value of high-sensitive troponin T (hsTnT) for risk prediction prior to non-cardiac surgery in comparison with the established revised cardiac index. Methods and results In this prospective, international multicentre observational study, 979 patients prior to non-cardiac surgery were enrolled. The endpoints were in-hospital mortality, the combination of death, acute myocardial infarction, cardiac arrest, cardio-pulmonary resuscitation, and acute decompensated heart failure. Twenty-five patients (2.6%) deceased and 36 (3.7%) of the patients experienced the combined endpoint. Cardiac markers were elevated in those patients who died when compared with survivors (hsTnT: 21 ng/L vs. 7 ng/L; P < 0.001; NT-proBNP: 576 pg/mL vs. 166 pg/mL; P < 0.001). Applying a cut-off for hsTnT of 14 ng/L and for NT-proBNP of 300 pg/mL, those patients with elevated hsTnT had a mortality of 6.9 vs. 1.2% (P < 0.001) and with elevated NT-proBNP 4.8 vs. 1.4% (P = 0.002). The highest AUC of the ROC curve was found for hsTnT as a predictor for mortality of 0.809. In a multivariate Cox regression analyses, hsTnT was the strongest independent predictor for the combined endpoint [HR 2.6 (95% CI: 1.3-5.3); P = 0.01]. Conclusion High-sensitive troponin T provides strong prognostic information in patients undergoing non-cardiac surgery incremental to the widely accepted revised cardiac inde

Synergic impact of oral anticoagulation control and renal function in determining major adverse events in atrial fibrillation patients undergoing percutaneous coronary intervention: insights from the AFCAS registry

In patients with atrial fibrillation (AF), quality of oral anticoagulation control as well as impaired renal function are associated with adverse outcomes. Our objective was to analyze if there was a synergistic impact of these factors in determining adverse outcomes in AF patients undergoing percutaneous coronary intervention and stent (PCI-S).Post-hoc analysis from the Atrial Fibrillation Undergoing Coronary Artery Stenting (AFCAS) registry. Poor oral anticoagulation control was defined as time in therapeutic range (TTR) < 65%, while impaired renal function as creatinine clearance (CrCl) < 60 ml/min.Of the whole cohort, 448 were eligible for this post-hoc analysis. Of these, 27.9% had TTR < 65%only (Group I), 19.2% had CrCl < 60 ml/min only (Group II), while 13.8% had both conditions (Group III). At follow-up, patients in Group III had a higher rate of major adverse cardiovascular and cerebrovascular events (MACCE) (p = 0.007), while patients in Groups I and III had higher rates of major bleeding. Kaplan-Meier analyses showed that patients in Group III had higher risk for MACCE (LogRank: 14.406, p = 0.003), while Group I and Group III patients had higher risk for major bleeding (LogRank: 12.290, p = 0.006). On Cox regression, presence of both conditions independently increased MACCE risk (p = 0.001), while TTR < 65% alone and the presence of both conditions were independently associated with major bleeding (p = 0.004 and p = 0.028, respectively).There was a synergic impact of oral anticoagulation control and renal function in determining major adverse events in AF patients undergoing PCI-S. Use of poor anticoagulation control and impaired renal function in combination would help identify AF patients undergoing PCI-S at risk for MACCE and/or major bleeding

METHODS: Post-hoc analysis from the Atrial Fibrillation Undergoing Coronary Artery Stenting (AFCAS) registry. Poor oral anticoagulation control was defined as time in therapeutic range (TTR) <65%, while impaired renal function as creatinine clearance (CrCl) <60 ml/min. RESULTS: Of the whole cohort, 448 were eligible for this post-hoc analysis. Of these, 27.9% had TTR <65%only (Group I), 19.2% had CrCl <60 ml/min only (Group II), while 13.8% had both conditions (Group III). At follow-up, patients in Group III had a higher rate of major adverse cardiovascular and cerebrovascular events (MACCE) (p = 0.007), while patients in Groups I and III had higher rates of major bleeding. Kaplan-Meier analyses showed that patients in Group III had higher risk for MACCE (LogRank: 14.406, p = 0.003), while Group I and Group III patients had higher risk for major bleeding (LogRank: 12.290, p = 0.006). On Cox regression, presence of both conditions independently increased MACCE risk (p = 0.001), while TTR <65% alone and the presence of both conditions were independently associated with major bleeding (p = 0.004 and p = 0.028, respectively).
