Background: Platelets have been involved in both surveillance and host defense against severe infection. To date, whether platelet phenotype or other hemostasis components could be associated with predisposition to sepsis in critical illness remains unknown. The aim of this work was to identify platelet markers that could predict sepsis occurrence in critically ill injured patients. Results: This single-center, prospective, observational, 7-month study was based on a cohort of 99 non-infected adult patients admitted to ICUs for elective cardiac surgery, trauma, acute brain injury and post-operative prolonged ventilation and followed up during ICU stay. Clinical characteristics and severity score (SOFA) were recorded on admission. Platelet activation markers, including fibrinogen binding to platelets, platelet membrane P-selectin expression, plasma soluble CD40L, and platelet-leukocytes aggregates were assayed by flow cytometry at admission and 48h later, and also at the time of sepsis diagnosis (Sepsis-3 criteria) and 7 days later for sepsis patients. Hospitalization data and outcomes were also recorded. Of the 99 patients, 19 developed sepsis after a median time of 5 days. SOFA at admission was higher; their levels of fibrinogen binding to platelets (platelet-Fg) and of D-dimers were significantly increased compared to the other patients. Levels 48h after ICU admission were no longer significant. Platelet-Fg % was an independent predictor of sepsis (P = 0.030). By ROC curve analysis cutoff points for SOFA (AUC=0.85) and Platelet-Fg (AUC=0.75) were 8 and 50%, respectively. The prior risk of sepsis (19%) increased to 50% when SOFA was above 8, to 46% when Platelet-Fg was above 50%, and to 87% when both SOFA and Platelet-Fg were above their cutoff values. By contrast, when the two parameters were below their cutoffs, the risk of sepsis was negligible (3.8%). Patients with sepsis had longer ICU and hospital stays and higher death rate. Conclusion: In addition to SOFA, platelet-bound fibrinogen levels assayed by flow cytometry within 24h of ICU admission help identifying critically ill patients at risk of developing sepsis.

Background: Synthetic phosphorothioate-modified CpG oligodeoxynucleotides (CpG ODNs) display potent immunostimulatory properties that are widely exploited in clinical trials of anticancer treatment. Unexpectedly, a recent study indicates that CpG ODNs activate human platelets via the immunoreceptor tyrosine-based activation motif (ITAM)-coupled receptor glycoprotein VI. Objective: To further analyze the mechanisms of CpG ODN-induced platelet activation and identify potential inhibitory strategies. Methods: In vitro analyses were performed on human and mouse platelets, and on cell lines expressing platelet ITAM receptors. CpG ODN platelet activating effects were evaluated in a mouse model of thrombosis. Results: We demonstrated platelet uptake of CpG ODNs, resulting in platelet activation and aggregation. The C-type lectin-like receptor 2 (CLEC-2) expressed in DT40 cells bound CpG ODNs. CpG ODN uptake did not occur in CLEC-2-deficient mouse platelets. Inhibition of human CLEC-2 with a blocking antibody inhibited CpG ODN-induced platelet aggregation. CpG ODNs caused CLEC-2 dimerization, and provoked its internalization. They induced dense granule release before the onset of aggregation. Accordingly, pretreating platelets with apyrase, or inhibiting P2Y12 with cangrelor or clopidogrel prevented CpG ODN platelet activating effect. In vivo, intravenously injected CpG ODN interacted with platelets adhered to mouse injured endothelium, and promoted thrombus growth, which was inhibited by CLEC-2 deficiency or by clopidogrel. Conclusions: CLEC-2 and P2Y12 are required for CpG ODN-induced platelet activation and thrombosis and might be targeted to prevent adverse events in patients at risk. [less ▲]

In patients suffering from systemic arterial hypertension, coronary artery disease, or heart failure, beta-blockers and angiotensin-convertase enzyme inhibitors play a major therapeutic and preventive role. Coronary artery disease remains the leading cause of mortality in industrialized countries. Unless adapted preventive strategy, notably pharmacological interventions, cardiovascular events in these patients remain high. One reason for this relative failure is represented by non-adherence to treatment. A treatment consisting in an association in one pill of several different molecules should confer a higher treatment compliance and thus efficacy. This article describes the characteristics of the first available dual association between a cardioselective beta-blocker agent, bisoprolol, and an angiotensin-convertase enzyme inhibitor, perindopril arginine.

Cardiovascular mortality of hemodialysis patients remains a major problem. The prevalence and incidence of atrial fibrillation in this population are more important than in the general population. The indication of antivitamin K therapy (AVK) in this context of atrial fibrillation must be weighted against the increased risk of bleeding. Unfortunately, and contrary to the general population, an indication of anticoagulation based on embolic or hemorrhagic risk scores is not as clearly established in the hemodialysis population. No prospective randomized study has investigated the benefit/risk balance of anticoagulant treatment in hemodialysis subjects. This article is a review of the current literature on this topic, showing the prevalence of thromboembolic but also bleeding events in the hemodialysis population. The impact of AVK treatment in this specific population is also reviewed. To the best of our knowledge, the indication of treatment must be individualized. [less ▲]

AIMS: Hypoalbuminemia is common in heart failure (HF), especially in elderly patients. It is associated with an increased risk of death. The present study sought to examine the prognostic significance of serum albumin level in the prediction of hospital mortality in patients admitted for acute non-ischemic HF. METHODS AND RESULTS: We examined the association between albumin and hospital mortality in a cohort of 546 patients admitted for acute non-ischemic HF. None of the patients had infectious disease, severe arrhythmias (atrial fibrillation, ventricular tachycardia, ventricular fibrillation), required invasive ventilation, or presented with acute coronary syndrome or primary valvular disease. Thirty-six patients (7%) died during the hospital stay. These patients were significantly older (78 +/- 9 vs. 72 +/- 12 years; P = 0.006), had higher heart rate (P < 0.0001), increased creatinine level (P = 0.01), lower systolic and diastolic blood pressures (P < 0.05), elevated leucocyte count (P = 0.001), and lower albumin levels (31.3 +/- 5.6 g/L vs. 36.9 +/- 4.1 g/L; P < 0.001). With multivariable analysis, age (P = 0.01), heart rate (P < 0.0003), diastolic blood pressure (P < 0.01), leukocyte count (P = 0.009), and serum albumin level (P < 0.0001) emerged as independent predictors of hospital mortality. Hypoalbuminemia (<34 g/L) yielded the best sensitivity (78.8%) and specificity (75%) for predicting hospital death. CONCLUSIONS: Serum albumin level measured at admission can serve as a simple prognostic factor in acute non-ischemic HF. Hypoalbuminemia is associated with increased risk of hospital mortality, especially in elderly patients. [less ▲]

Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories. Detailed recommendations for the echocardiographic assessment of valve stenosis were published by the European Association of Echocardiography and the American Society of Echocardiography in 2009. In the meantime, numerous new studies on aortic stenosis have been published with particular new insights into the difficult subgroup of low gradient aortic stenosis making an update of recommendations necessary. The document focuses in particular on the optimization of left ventricular outflow tract assessment, low flow, low gradient aortic stenosis with preserved ejection fraction, a new classification of aortic stenosis by gradient, flow and ejection fraction, and a grading algorithm for an integrated and stepwise approach of artic stenosis assessment in clinical practice.

Heart valve disease is common and a major indication for imaging. Echocardiography is the first-line imaging technique for diagnosis, assessment, and serial surveillance. However, other modalities, notably cardiac magnetic resonance imaging and computerized tomography, are used if echocardiographic imaging is suboptimal or to obtain complementary information, particularly to aid risk assessment in individual patients. This review is a summary of current evidence for state-of-the-art clinical practice to inform appropriateness criteria for heart valve disease. It is divided according to common clinical scenarios: detection of valve disease, assessment of the valve and other cardiac structures, risk assessment, screening, and intervention. [less ▲]

Aims: The present Euro-Filling report aimed at comparing the diagnostic accuracy of the 2009 and 2016 echocardiographic grading algorithms for predicting invasively measured left ventricular filling pressure (LVFP). Method and results: A total of 159 patients who underwent simultaneous evaluation of echo estimates of LVFP and invasive measurements of LV end-diastolic pressure (LVEDP) were enrolled at nine EACVI centres. Thirty-nine (25%) patients had a reduced LV ejection fraction (<50%), 77 (64%) were in NYHA ≥ II, and 85 (53%) had coronary artery disease. Sixty-four (40%) patients had elevated LVEDP (≥15 mmHg). Taken individually, all echocardiographic Doppler estimates of LVFP (E/A, E/e', left atrial volume, tricuspid regurgitation jet velocity) were marginally correlated with LVEDP. By using the 2016 recommendations, 65% of patients with normal non-invasive estimate of LVFP had normal LVEDP, while 79% of those with elevated non-invasive LVFP had elevated invasive LVEDP. By using 2009 recommendations, 68% of the patients with normal non-invasive LVFP had normal LVEDP, while 55% of those with elevated non-invasive LVFP had elevated LVEDP. The 2016 recommendations (sensitivity 75%, specificity 74%, positive predictive value 39%, negative predictive value 93%, AUC 0.78) identified slightly better patients with elevated invasive LVEDP (≥ 15 mmHg) as compared with the 2009 recommendations (sensitivity 43%, specificity 75%, positive predictive value 49%, negative predictive value 71%, AUC 0.68). Conclusion: The present Euro-Filling study demonstrates that the new 2016 recommendations for assessing LVFP non-invasively are fairly reliable and clinically useful, as well as superior to the 2009 recommendations in estimating invasive LVEDP.

Aims: Assessment of left ventricular (LV) volumes and ejection fraction (LVEF) with cardiac imaging is important in the selection of patients for cardiac resynchronization therapy (CRT). Several observational studies have explored the role of imaging-derived LV dyssynchrony parameters to predict the response to CRT, but have yielded inconsistent results, precluding the inclusion of imaging-derived LV dyssynchrony parameters in current guidelines for selection of patients for CRT. METHODS: The EuroCRT is a large European multicentre prospective observational study led by the European Association of Cardiovascular Imaging. We aim to explore if combing the value of cardiac magnetic resonance (CMR) and echocardiography could be beneficial for selecting heart failure patients for CRT in terms of improvement in long-term survival, clinical symptoms, LV function, and volumes. Speckle tracking echocardiography will be used to assess LV dyssynchrony and wasted cardiac work whereas myocardial scar will be assessed with late gadolinium contrast enhanced CMR. All data will be measured in core laboratories. The study will be conducted in European centres with known expertise in both CRT and multimodality cardiac imaging. [less ▲]

AIM: The aim of this study was to assess preoperative determinants, prevalence, and prognostic impact of left ventricular (LV) reverse remodeling (LVRR) in patients with secondary mitral regurgitation (SMR), undergoing MitraClip implantation (MCi). METHODS: From March 2012 to January 2015, a total of 41 consecutive patients with moderate-to-severe SMR treated successfully with MCi were enrolled. All patients underwent clinical and echocardiographic follow-up after MCi. Global longitudinal strain (GLS) was obtained using two dimensional speckle tracking analysis. A reduction in LV end-systolic volume more than 10% compared with baseline was considered as a marker of LVRR. Patients were divided into two groups according to the presence or absence of LVRR. Cardiac events were defined as the occurrence of cardiac death, rehospitalization for worsening heart failure, and mitral valve surgery. RESULTS: On univariable analysis, EuroSCORE II and GLS were associated with LVRR. On multivariable logistic regression analysis, GLS was the only independent correlate of LVRR (P = 0.004). A receiver operating characteristic curve identified a cutoff value for GLS of -9.25% (P < 0.001) associated with LVRR, with a sensitivity and specificity of 81 and 74%, respectively. New York Heart Failure Association class more than 2 after MCi, absence of LVRR after MCi, and preoperative GLS more than -9.25% were significantly correlated with adverse cardiac events at long-term follow-up. On multivariable logistic regression analysis, GLS was the only independent predictor of composite adverse cardiac events at 2-year follow-up. CONCLUSION: A worse preoperative GLS predicts no LVRR and is associated with adverse long-term outcome after successful MCi for SMR. [less ▲]
