SummaryBleeding risk is increased in patients with atrial fibrillation (AF) and moderate to severe kidney disease (KD); however, the implication of mild KD on bleeding remains unclear. The aim of this study was to determine whether the presence of mild KD increases risk for major bleeding (MB) in patients with AF undergoing percutaneous coronary intervention with stent implantation (PCI-S). Two hundred eighty-five patients were included. Patients were classified into three kidney function groups: moderate to severe KD (n=91; <60 ml/min/1.73 m2), mild KD (n=139; 60–89 ml/min/1.73 m2) and non-KD (n=55; ≥90 ml/min/1.73 m2). Estimated glomerular filtration rate was calculated using the simplified Modification of Diet in Renal Disease equation. Patients were followed for one year, and the occurrence of MB was obtained in all. A total of 28 patients (9.8%) presented MB. MB complications examined as a function of KD groups revealed that there was a graded increase in MB with worsening renal function (non KD=1.8%, mild KD=7.9%, moderate to severe KD=17.6%; p <0.001). Multivariable Cox regression analysis showed that mild KD was associated with nearly a 2.5-fold (2.43 95% confidence interval 1.11–5.34, p=0.039) increase in the risk of MB as compared with non-KD patients. Other independent predictors of MB were moderate-severe KD, anaemia and triple antithrombotic therapy after PCI-S (C-index=0.76). In this population, mild KD confers a significantly increase in the risk for MB complications. Future studies should assess the potential role of incorporating mild KD into the bleeding risk scales to improve the stratification of these patients.

African Americans (AAs) and obese individuals have increased thrombotic risk. This study evaluated the effectiveness and safety of rivaroxaban versus warfarin in obese, AAs with nonvalvular atrial fibrillation (NVAF) or venous thromboembolism (VTE). Optum® De-Identified Electronic Health Record (EHR) data was used to perform separate propensity-score matched analyses of adult, oral anticoagulant (OAC)-naïve AAs with NVAF or acute VTE, respectively; who had a body mass index≥30kg/m2 and ≥12-months EHR activity with ≥1-encounter before OAC initiation. Cox regression was performed and reported as hazard ratios (HRs) with 95% confidence intervals (CIs). For the NVAF analysis, 1,969 rivaroxaban- and 1,969 warfarin-users were matched. Rivaroxaban was not associated with a difference in stroke/systemic embolism versus warfarin (HR = 0.88, 95%CI = 0.60-1.28), but less major bleeding (HR = 0.68, 95%CI = 0.50-0.94) was observed. Among 683 rivaroxaban-users with VTE, 1:1 matched to warfarin-users, rivaroxaban did not alter recurrent VTE (HR = 1.36, 95%CI = 0.79-2.34) or major bleeding (HR = 0.80, 95%CI = 0.37-1.71) risk versus warfarin at 6-months (similar findings observed at 3- and 12-months). Rivaroxaban appeared to be associated with similar thrombotic, and similar or lower major bleeding risk versus warfarin in these obese, AA cohorts.

Objective: To synthesize the literature and provide guidance to practitioners regarding double therapy (DT) and triple therapy (TT) in patients with atrial fibrillation (AF) requiring percutaneous coronary intervention (PCI). Data Sources: PubMed and MEDLINE (January 2000 to February 2018) were searched using the following terms: atrial fibrillation, myocardial infarction, acute coronary syndrome, percutaneous coronary intervention, anticoagulation, dual-antiplatelet therapy, clopidogrel, aspirin, ticagrelor, prasugrel, and triple therapy. Study Selection and Data Extraction: The results included randomized and nonrandomized clinical trials and meta-analyses. Each study was reported based on study design, population, intervention, comparator, and key cardiovascular (CV) and bleeding outcomes. Data Synthesis: A total of 15 studies were included in the review. The majority of studies evaluating DT and TT utilized clopidogrel and warfarin as components of the regimen, although there are emerging data with newer agents. Evidence purporting DT regimens to be equally effective in preventing CV events and improved safety profiles compared with TT regimens included populations with relatively low risk for recurrent CV events, and many of these studies were observational in nature. Overall, current evidence as well as American and European guidelines support the use of TT in patients with AF who require PCI for the least possible amount of time, depending on patient-specific factors involving bleeding and thrombosis. Conclusions: In the majority of patients with AF who require PCI, TT should be used for the shortest period of time possible. DT regimens may be used in patients requiring PCI who have low risk for thrombosis and/or high bleeding risk.

Patients with atrial fibrillation who have concurrent coronary artery disease requiring percutaneous coronary intervention are subsequently prescribed dual antiplatelet therapy and anticoagulation resulting in triple therapy (TT). Ticagrelor, a reversibly binding P2Y12 antiplatelet agent, has shown superiority to clopidogrel in prevention of ischemic events and death, but is also associated with a small increase in the incidence of intracranial bleeding. This bleeding risk may be enhanced in the setting of TT. The objective of this report is to describe a case of a 70-year-old male prescribed TT with ticagrelor and to review the current literature on the safety of ticagrelor as a part of TT.

Background. The present study aimed to evaluate the prevalence and prognosis of residual lipid abnormalities in statin-treated acute coronary syndrome (ACS) patients after percutaneous coronary intervention (PCI).Subjects and Methods. A total of 3,047 ACS patients who underwent PCI and received statin therapy were included. Plasma concentrations of LDL-C, HDL-C, and TG were measured. For the follow-up study, major adverse cardiovascular cerebrovascular events (MACCE; including total death, cardiovascular death, myocardial infarction, and revascularization) were documented.Results. A total of 93.14% of all individuals were followed up for 18.1 months (range, 0–29.3 months). Of all 3,047 patients, those with a suboptimal goal were 67.75%, 85.85%, and 33.64% for LDL-C, HDL-C, and TG levels, respectively. Multiple Cox regression analysis revealed there were significant increases in cumulative MACCE of 41% (HR = 1.41, 95% CI [1.09–1.82],p=0.008), and revascularization of 48% (HR = 1.48, 95% CI [1.10–1.99],p=0.01) in low HDL-C patients with ACS after PCI, but not the high TG group at the end of study.Conclusions. Our results showed there is high rate of dyslipidemia in Chinese ACS patients after PCI. Importantly, low HDL-C but not high TG levels are associated with higher MACCE and revascularization rates in ACS patients after PCI.

Background The Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE‐DAPT) score has been shown to predict out‐of‐hospital major bleeding after myocardial infarction treated with percutaneous coronary intervention and dual antiplatelet therapy (DAPT). However, large validation studies have been scarce and the discriminative ability for patients with a preexisting bleeding risk factor (elderly, underweight, women, anemia, kidney dysfunction, or cancer) in a real‐world setting is unknown. Methods and Results Patients undergoing percutaneous coronary intervention for myocardial infarction between 2008 and 2017 were included from the SWEDEHEART (Swedish Web System for Enhancement of Evidence‐Based Care in Heart Disease Evaluated According to Recommended Therapies) registry (n=66 295). The predictive value of the PRECISE‐DAPT score for rehospitalization with major bleeding during dual antiplatelet therapy was evaluated using receiver operating characteristic analyses. A high PRECISE‐DAPT score (≥25; n=13 894) was associated with increased risk of major bleeding (3.9% versus 1.8%; hazard ratio [HR], 2.2; 95% CI, 2.0–2.5; P <0.001) compared with a non‐high score (<25; n=52 401). The score demonstrated a c‐statistic of 0.64 (95% CI, 0.63–0.66). The discriminative ability of the score to further stratify bleeding risk in patients with preexisting bleeding risk factors was poor, especially in patients who are elderly (c‐statistic=0.57; 95% CI, 0.55–0.60) or underweight (c‐statistic=0.56; 95% CI, 0.51–0.61), for whom a non‐high PRECISE‐DAPT score was associated with similar bleeding risk as a high PRECISE‐DAPT score in the general myocardial infarction population. Conclusions In this nationwide population‐based study, the PRECISE‐DAPT score performed moderately in the general myocardial infarction population and poorly in patients with preexisting bleeding risk factors, where its usefulness seems limited.

Abstract Background The relation between complex percutaneous coronary intervention (PCI), high bleeding risk (HBR), and adverse events after coronary artery implantation of drug-eluting stents has been incompletely characterized. This study sought to investigate the ischemic and bleeding events after complex PCI including a stratification according to HBR estimated by PARIS bleeding risk score. Methods Between January 2013 and December 2013, 10,167 consecutive patients undergoing PCI were prospectively enrolled in Fuwai PCI Registry. Complex PCI was defined when having at least one of the following characteristics: 3 vessels treated, ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length &gt;60 mm, treatment of chronic total occlusion, unprotected left main PCI, in-stent restenosis target lesion, and severely calcified lesion. The primary ischemic endpoint was major adverse cardiovascular events (MACE) [composite of cardiac death, myocardial infarction, and definite/probable stent thrombosis], and primary bleeding endpoint was Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding. Results The median duration of follow-up was 29 months. In adjusted Cox regression analysis, patients having complex PCI procedures experienced higher risks of MACE (hazard ratio [HR]: 1.63, 95% confidence interval [CI]: 1.38–1.92; P&lt;0.001), compared with non-complex PCI. In contrast, the risk of clinically relevant bleeding was statistically similar between the 2 groups (HR: 0.86 [0.66–1.11]; P=0.238). There was no statistical interaction between HBR (PARIS bleeding score ≥8 or &lt;8) and complex PCI in regard to MACE (adjusted Pinteraction=0.388) and clinically relevant bleeding (adjusted Pinteraction=0.279). Conclusions Patients who had undergone complex PCI resulted in substantially more ischemic events, without an increase in clinically relevant bleeding risk; and these associations did not seem to be modified by HBR status. More intensified antiplatelet therapy may be beneficial for patients with complex percutaneous coronary revascularization procedures. Funding Acknowledgement Type of funding source: Foundation.

The role of activation of the coagulation and fibrinolysis system in the pathogenesis and prognosis of cardiovascular diseases (CVDs) has drawn wide attention. Recently, the D-dimer to fibrinogen ratio (DFR) is considered as a useful biomarker for the diagnosis and prognosis of ischemic stroke and pulmonary embolism. However, few studies have explored the relationship between DFR and cardiovascular disease. In our study, patients were divided into 2 groups according to DFR value: the lower group (DFR < 0.52, n = 2123) and the higher group (DFR ≥ 0.52, n = 1073). The primary outcome was all-cause mortality (ACM) and cardiac mortality (CM). The average follow-up time was 37.59 ± 22.24 months. We found that there were significant differences between the 2 groups in term of ACM (2.4% vs 6.6%, P < 0.001) and CM (1.5% vs 4.0%, P < 0.001). Kaplan–Meier analyses showed that elevated DFR had higher incidences of ACM (log rank P < 0.001) and CM (log rank P < 0.001). Multivariate Cox regression analyses showed that DFR was an independent predictor of ACM (HR = 1.743, 95%CI: 1.187-2.559 P = 0.005) and CM (HR = 1.695, 95%CI: 1.033-2.781 P = 0.037). This study indicates that DFR is an independent and novel predictor of long-term ACM and CM in post-PCI patients with CAD.
