B-type natriuretic peptide is released from the ventricles of the heart in response to hemodynamic stress, and blood levels of B-type natriuretic peptide may be useful in the diagnosis of heart failure. In this study, a rapid, bedside immunoassay for B-type natriuretic peptide was used to make or exclude the diagnosis of heart failure in patients with acute dyspnea from various causes. The assay was found to have good sensitivity and excellent specificity in the diagnosis of heart failure. Rapid measurement of this peptide is useful in establishing or excluding the diagnosis of congestive heart failure. Currently, there are 5 million Americans with congestive heart failure, with nearly 500,000 new cases every year. 1 The prevalence of symptomatic heart failure in the general European population ranges from 0.4 percent to 2.0 percent. 2 Because of the high total direct costs of care for heart failure, estimated at $10 billion to $38 billion per year, the Health Care Financing Administration (now the Centers for Medicare and Medicaid Services) targeted heart failure as the disease most worthy of cost-effective management. 3 To provide cost-effective treatment for patients with congestive heart failure, rapid and accurate differentiation of congestive heart failure from other . . .

In this randomized trial, patients with STEMI and multivessel disease were assigned to undergo complete revascularization based on guidance from fractional flow reserve or angiography. At 1 year, there was no significant difference between the two groups in a composite of death, MI, or unplanned hospitalization with urgent revascularization.

Despite aggressive pharmacotherapy and stenting, there is a residual risk of major adverse cardiovascular events among patients with acute coronary syndrome. High-density lipoprotein (HDL) has been a major target for secondary acute coronary syndrome prevention; however, a better understanding of the physiologic function of HDL has demonstrated that a high cholesterol efflux capacity, rather than high HDL concentrations alone, may be critical to improving outcomes. CSL112, a reconstituted, infusible human apolipoprotein A-I, has been demonstrated to increase cholesterol efflux capacity and to have a protective effect in experimental models of atherosclerotic cardiovascular disease. The AEGIS-I trial (ClinicalTrials.govNCT02108262) is a phase 2b, multicenter, randomized, placebo-controlled, dose-ranging clinical trial to evaluate the hepatic and renal safety of multiple administrations of 2 doses of CSL112 among subjects with acute myocardial infarction (AMI). Approximately 1,200 subjects (400 per treatment group) with either normal renal function or mild renal impairment will be enrolled up to 7 days after an AMI and will be stratified by renal function and randomized in a 1:1:1 ratio to either 1 of 2 doses of CSL112 (either 2 g or 6 g) or placebo as a weekly 2-hour infusion over the course of 4 consecutive weeks. The coprimary safety endpoints will be the incidence of hepatic and renal toxicity, defined as either confirmed ALT >3 × ULN, total bilirubin >2 × ULN, serum creatinine ≥1.5×baseline value, or a new requirement for renal replacement therapy through the end of the active treatment period. The AEGIS-I trial will characterize the safety profile of CSL112, a reconstituted formulation of apolipoprotein A-I, and will assess if administration to patients with a recent AMI is associated with a clinically significant alteration in either liver or kidney function when compared with placebo.

For 20 years, dual antiplatelet therapy (DAPT), consisting of the combination of aspirin and a platelet P2Y12 receptor inhibitor, has been the gold standard of antithrombotic pharmacology after percutaneous coronary intervention (PCI). In the past 5 years, several investigations have challenged this paradigm by testing the efficacy and safety of P2Y12 inhibitor monotherapy (that is, without aspirin) following a short course of DAPT. Collectively, these studies suggested a reduction in the risk of major bleeding and no significant increase in thrombotic or ischaemic events compared with guideline-recommended DAPT. Current recommendations are evolving to inform clinical practice on the ideal candidates for P2Y12 inhibitor monotherapy after PCI. Generalizing the results of studies of P2Y12 inhibitor monotherapy requires a thorough understanding of their design, populations, interventions, comparators and results. In this Review, we provide an up-to-date overview on the use of P2Y12 inhibitor monotherapy after PCI, including supporting pharmacodynamic and clinical evidence, practical recommendations and future directions.The evolution of stent design has reduced the incidence of stent thrombosis, meaning that the duration of dual antiplatelet therapy after percutaneous coronary intervention (PCI) might be shortened. In this Review, the authors describe the current evidence base and ongoing clinical trials into the use of P2Y12 inhibitor monotherapy after PCI.

Background Physicians involved in primary prevention are key players in CVD risk control strategies, but the expected reduction in CVD risk that would be obtained if all patients attending primary care had their risk factors controlled according to current guidelines is unknown. The objective of this study was to estimate the excess risk attributable, firstly, to the presence of CVD risk factors and, secondly, to the lack of control of these risk factors in primary prevention care across Europe. Methods Cross-sectional study using data from the European Study on Cardiovascular Risk Prevention and Management in Daily Practice (EURIKA), which involved primary care and outpatient clinics involved in primary prevention from 12 European countries between May 2009 and January 2010. We enrolled 7,434 patients over 50 years old with at least one cardiovascular risk factor but without CVD and calculated their 10-year risk of CVD death according to the SCORE equation, modified to take diabetes risk into account. Results The average 10-year risk of CVD death in study participants (N = 7,434) was 8.2%. Hypertension, hyperlipidemia, smoking, and diabetes were responsible for 32.7 (95% confidence interval 32.0-33.4), 15.1 (14.8-15.4), 10.4 (9.9-11.0), and 16.4% (15.6-17.2) of CVD risk, respectively. The four risk factors accounted for 57.7% (57.0-58.4) of CVD risk, representing a 10-year excess risk of CVD death of 5.66% (5.47-5.85). Lack of control of hypertension, hyperlipidemia, smoking, and diabetes were responsible for 8.8 (8.3-9.3), 10.6 (10.3-10.9), 10.4 (9.9-11.0), and 3.1% (2.8-3.4) of CVD risk, respectively. Lack of control of the four risk factors accounted for 29.2% (28.5-29.8) of CVD risk, representing a 10-year excess risk of CVD death of 3.12% (2.97-3.27). Conclusions Lack of control of CVD risk factors was responsible for almost 30% of the risk of CVD death among patients participating in the EURIKA Study.

The safety and efficacy of drug-eluting stents (DES) in the treatment of coronary artery disease have been assessed in several randomised trials. However, none of these trials were powered to assess the safety and efficacy of DES in women because only a small proportion of recruited participants were women. We therefore investigated the safety and efficacy of DES in female patients during long-term follow-up. We pooled patient-level data for female participants from 26 randomised trials of DES and analysed outcomes according to stent type (bare-metal stents, early-generation DES, and newer-generation DES). The primary safety endpoint was a composite of death or myocardial infarction. The secondary safety endpoint was definite or probable stent thrombosis. The primary efficacy endpoint was target-lesion revascularisation. Analysis was by intention to treat. Of 43 904 patients recruited in 26 trials of DES, 11 557 (26·3%) were women (mean age 67·1 years [SD 10·6]). 1108 (9·6%) women received bare-metal stents, 4171 (36·1%) early-generation DES, and 6278 (54·3%) newer-generation DES. At 3 years, estimated cumulative incidence of the composite of death or myocardial infarction occurred in 132 (12·8%) women in the bare-metal stent group, 421 (10·9%) in the early-generation DES group, and 496 (9·2%) in the newer-generation DES group (p=0·001). Definite or probable stent thrombosis occurred in 13 (1·3%), 79 (2·1%), and 66 (1·1%) women in the bare-metal stent, early-generation DES, and newer-generation DES groups, respectively (p=0·01). The use of DES was associated with a significant reduction in the 3 year rates of target-lesion revascularisation (197 [18·6%] women in the bare-metal stent group, 294 [7·8%] in the early-generation DES group, and 330 [6·3%] in the newer-generation DES group, p<0·0001). Results did not change after adjustment for baseline characteristics in the multivariable analysis. The use of DES in women is more effective and safe than is use of bare-metal stents during long-term follow-up. Newer-generation DES are associated with an improved safety profile compared with early-generation DES, and should therefore be thought of as the standard of care for percutaneous coronary revascularisation in women.

Background We aimed to assess associations between circulating IL‐18 concentrations and cardiovascular outcomes in patients with acute coronary syndromes (ACS). Hypothesis and Methods Plasma IL‐18 concentrations were measured at admission, discharge, 1 month, and 6 months in patients with ACS in the PLATelet inhibition and patient Outcomes (PLATO) trial. Associations with outcomes were evaluated with Cox regression models on the composite of CV death, spontaneous myocardial infarction (sMI), or stroke; and on CV death or sMI separately, including adjustment for clinical risk factors and biomarkers (cTnT‐hs, NT‐proBNP, cystatin C, CRP‐hs, and GDF‐15). Results Median IL‐18 concentrations at baseline, discharge, 1 month, and 6 months were 237, 283, 305, and 320 ng/L (n = 16 636). Male sex, obesity, diabetes, and plasma levels of cystatin C, GDF‐15, and CRP‐hs were independently associated with higher IL‐18 levels. Higher baseline IL‐18 levels were associated with the composite endpoint and with CV death (hazard ratio [HR] 1.05, 95% confidence interval [95% CI] 1.02‐1.07 and HR 1.10, 95% CI 1.06‐1.14, respectively, per 25% increase of IL‐18 levels). Associations remained significant after adjustment for clinical variables but became non‐significant after adjustment for all biomarkers (HR 1.01, 95% CI 0.98‐1.04 and HR 1.04, 95% CI 1.00‐1.08, respectively). There were no associations with sMI. Conclusions In ACS patients, IL‐18 concentrations increased after the acute event and remained increased for 6 months. Baseline IL‐18 levels were significantly associated with CV mortality, independent of clinical characteristics and indicators of renal/cardiac dysfunction but this association was attenuated after adjustment for multiple biomarkers.

Non‐vitamin K antagonists oral anticoagulants (NOACs) have recently challenged vitamin‐K antagonists (VKAs) for stroke and systemic embolism prophylaxis in patients with non‐valvular atrial fibrillation (NVAF). Nevertheless, little information is available in routine clinical practice for France. The aim of this study is to describe the effectiveness and safety of apixaban, rivaroxaban, dabigatran or VKAs in routine clinical practice in adult NVAF patients for the prevention of stroke and systemic embolism in France. The NAXOS study is a nationwide observational retrospective cohort generated from the French national healthcare insurance database (SNIIRAM—a comprehensive in‐ and outpatient healthcare consumption database), consisting of eight distinct sub‐cohorts of anticoagulant‐naive or anticoagulant‐experienced patients diagnosed with NVAF, newly initiated with either NOACs (dabigatran, rivaroxaban or apixaban) or VKAs. Patients will be included if initiating a new anticoagulant treatment for AF during the study period from 1 January 2014 to 31 December 2016. Primary effectiveness outcome will be the incidence of stroke or systemic thromboembolic events; primary safety outcome will be the incidence of major bleeding during the exposure period. The NAXOS study will provide routine clinical practice data on the effectiveness and safety profiles of apixaban vs other NOACs and VKAs in the prevention of stroke and systemic embolism in adult patients with NVAF in clinical practice conditions in France.

B-type natriuretic peptide (BNP) is valuable in diagnosing heart failure (HF), but its utility in obese patients is unknown. Studies have suggested a cut-point of BNP > or = 100 pg/mL for the diagnosis of HF; however, there is an inverse relation between BNP levels and body mass index. We evaluated differential cut-points for BNP in diagnosing acute HF across body mass index levels to determine whether alternative cut-points can improve diagnosis. The Breathing Not Properly Multinational Study was a 7-center, prospective study of 1586 patients who presented to the Emergency Department with acute dyspnea. B-type natriuretic peptide was measured on arrival. Height and weight data were available for 1368 participants. The clinical diagnosis of HF was adjudicated by 2 independent cardiologists who were blinded to BNP results. Heart failure was the final diagnosis in 46.1%. Mean BNP levels (pg/mL) in lean, overweight/obese, and severely/morbidly obese patients were 643, 462, and 247 for patients with acute HF, and 52, 35, and 25 in those without HF, respectively (P < .05 for all comparisons except 35 vs 25). B-type natriuretic peptide cut-points to maintain 90% sensitivity for a HF diagnosis were 170 pg/mL for lean subjects, 110 pg/mL for overweight/obese subjects, and 54 pg/mL in severely/morbidly obese patients. Body mass index influences the selection of cut-points for BNP in diagnosing acute HF. A lower cut-point (BNP > or = 54 pg/mL) should be used in severely obese patients to preserve sensitivity. A higher cut-point in lean patients (BNP > or = 170 pg/mL) could be used to increase specificity.
