TL;DR: In this paper, the effects of different degrees of pulsatility on the incidence of nonsurgical bleeding were assessed by means of the LVAD parameter pulsatility index (PI) and by the echocardiographic assessment of aortic valve opening during the first 3 months of LVAD support.
Abstract: Background—Bleeding is an important cause of morbidity and mortality in patients with continuous-flow left ventricular assist devices (LVADs). Reduced pulsatility has been implicated as a contributing cause. The aim of this study was to assess the effects of different degrees of pulsatility on the incidence of nonsurgical bleeding. Methods and Results—The Utah Transplantation Affiliated Hospitals (U.T.A.H.) heart failure and transplant program databases were queried for patients with end-stage heart failure who required support with the continuous-flow LVAD HeartMate II (Thoratec Corp, Pleasanton, CA) between 2004 and 2012. Pulsatility was evaluated by means of the LVAD parameter pulsatility index (PI) and by the echocardiographic assessment of aortic valve opening during the first 3 months of LVAD support. PI was analyzed as a continuous variable and also stratified according to tertiles of all the PI measurements during the study period (low PI: 5.2). Major ...

TL;DR: Investigation of randomized clinical trials from 1980 to October 2011 found incidence of angioedema with ARBs and DRI was <1/2 than that with ACE inhibitors and not significantly different from placebo.
Abstract: Angioedema is a rare, potentially life-threatening adverse event of renin–angiotensin system inhibitors. The objective of the present study was to determine the risk of angioedema from randomized clinical trials. A PubMed/CENTRAL/EMBASE search was made for randomized clinical trials from 1980 to October 2011 in patients on angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), or direct renin inhibitor (DRI). Trials with a total number of patients ≥100 and a duration of ≥8 weeks were included for analysis. Incidence of angioedema was pooled by weighing the incident rate of each trial by the inverse of the variance. Twenty-six trials with 74,857 patients in the ACE inhibitor arm with 232,523 person-years of follow-up, 19 trials with 35,479 patients on ARB with 122,293 person-years of follow-up, and 2 trials with 5,141 patients on DRI with 1,735 person-years of follow-up met the inclusion criteria and were included in the analysis. In head-to-head comparison in 7 trials, risk of angioedema with ACE inhibitors was 2.2 times higher than with ARBs (95% confidence interval [CI] 1.5 to 3.3). With ACE inhibitors and ARBs, incidence of angioedema was higher in heart failure trials compared to hypertension or coronary artery disease trials without heart failure (p

TL;DR: Mavacamten, a novel myosin inhibitor, was well tolerated in most subjects with symptomatic nHCM and treatment was associated with a significant reduction in NT-proBNP and cTnI, suggesting improvement in myocardial wall stress.

Guidelines summarize and evaluate all available evidence at the time of the writing process, on a particular issue with the aim of assisting health professionals in selecting the best management strategies for an individual patient, with a given condition, taking into account the impact on outcome, as well as the risk-benefit-ratio of particular diagnostic or therapeutic means. Guidelines and recommendations should help the health professionals to make decisions in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate.
A great number of Guidelines have been issued in recent years by the European Society of Cardiology (ESC) as well as by other societies and organisations. Because of the impact on clinical practice, quality criteria for the development of guidelines have been established in order to make all decisions transparent to the user. The recommendations for formulating and issuing ESC Guidelines can be found on the ESC website (http://www.escardio.org/guidelines-surveys/esc-guidelines/about/Pages/rules-writing.aspx). ESC Guidelines represent the official position of the ESC on a given topic and are regularly updated.
Members of this Task Force were selected by the ESC to represent professionals involved with the medical care of patients with this pathology. Selected experts in the field undertook a comprehensive review of the published evidence for management (including diagnosis, treatment, prevention and rehabilitation) of a given condition according to ESC Committee for Practice Guidelines (CPG) policy. A critical evaluation of diagnostic and therapeutic procedures was performed including assessment of the risk-benefit-ratio. Estimates of expected health outcomes for larger populations were included, where data exist. The level of evidence and the strength of recommendation of particular management options were weighed and graded according to predefined scales, as outlined in Tables 1 and 2 .
