Systematic Review of Medicine-Related Problems in Adult Patients with Atrial Fibrillation on Direct Oral Anticoagulants
New oral anticoagulant agents continue to emerge on the market and their safety requires assessment to provide evidence of their suitability for clinical use. There-fore, we searched standard databases to summarize the English language literature on medicine-related problems (MRPs) of direct oral anticoagulants DOACs (dabigtran, rivaroxban, apixban, and edoxban) in the treatment of adults with atri-al fibrillation. Electronic databases including Medline, Embase, International Pharmaceutical Abstract (IPA), Scopus, CINAHL, the Web of Science and Cochrane were searched from 2008 through 2016 for original articles. Studies pub-lished in English reporting MRPs of DOACs in adult patients with AF were in-cluded. Seventeen studies were identified using standardized protocols, and two reviewers serially abstracted data from each article. Most articles were inconclusive on major safety end points including major bleeding. Data on major safety end points were combined with efficacy. Most studies inconsistently reported adverse drug reactions and not adverse events or medication error, and no definitions were consistent across studies. Some harmful drug effects were not assessed in studies and may have been overlooked. Little evidence is provided on MRPs of DOACs in patients with AF and, therefore, further studies are needed to establish the safety of DOACs in real-life clinical practice

Prognostic value of right ventricular remodelling in patients undergoing concomitant aortic and mitral valve surgery
Aims Long-term risk stratification and surgical timing remain suboptimal in concomitant aortic and mitral (double) valve surgery. This study sought to examine the predictors, changes, and prognostic implications of right ventricular (RV) remodelling in patients undergoing double-valve surgery. Methods and results In 152 patients undergoing double-valve surgery, four RV remodelling patterns were characterized using transthoracic echocardiography: normal RV size and systolic function (Pattern 1); dilated RV (tricuspid annulus diameter >35 mm) with normal systolic function (Pattern 2); normal RV size with systolic dysfunction (percentage RV fractional area change <35%; Pattern 3); and dilated RV with systolic dysfunction (Pattern 4). The primary endpoint was the composite of heart failure hospitalization and all-cause mortality. Patterns 1, 2, 3, and 4 RV remodelling were present in 41, 20, 23, and 16% of patients, respectively. Patients with Stage 4 RV remodelling had worse renal function, higher EuroSCORE II, and impaired left ventricular ejection fraction. During a 3.7-year median follow up, 45 adverse events occurred. Patterns 3 and 4 RV remodelling were associated with significantly higher adverse event rates compared with Pattern 1 (37 and 75% vs. 11%, P < 0.01) and had incremental prognostic value when added to clinical parameters and EuroSCORE II (chi(2) increased from 30 to 66, P < 0.01). At 1 year after surgery (n = 100), Patterns 3 and 4 RV remodelling had a higher risk of adverse events compared with Pattern 1. Conclusion Right ventricular remodelling was strongly related to adverse outcomes and deserves consideration as part of the risk and decision-making algorithms in double-valve surgery

Left ventricular dysfunction assessed by speckle-tracking strain analysis in patients with systemic sclerosis: Relationship to functional capacity and ventricular arrhythmias
OBJECTIVE Systemic sclerosis (SSc) is a connective tissue disease characterized by vascular inflammation and fibrosis. Visceral involvement, including cardiac manifestations, can lead to severe clinical complications, such as congestive heart failure, arrhythmias, and sudden death. Conventional echocardiography parameters have limited sensitivity to detect subtle myocardial dysfunction in patients with SSc. The aim of this study was to assess, using novel speckle-tracking strain analysis, the presence of myocardial dysfunction in patients with SSc, and to investigate its relationship to functional capacity and ventricular arrhythmias. METHODS A total of 104 patients with SSc (mean ± SD age 54 ± 12 years, 77% female) were included and underwent cardiopulmonary exercise testing, 24-hour electrocardiography (EKG) Holter monitoring, and transthoracic echocardiography. For comparison, 37 matched healthy control subjects were included. RESULTS The total patient population consisted of 51 patients with limited cutaneous SSc and 53 with diffuse cutaneous SSc. Peak VO(2) was a mean ± SD 91 ± 20% predicted, and 28 patients had abnormal findings (ventricular tachycardia or ventricular ectopics >100/day) on EKG Holter monitoring. Patients with SSc, as compared with controls, had impaired global longitudinal and circumferential strains (mean ± SD -18.2 ± 1.8% versus -21.3 ± 1.7% and -18.2 ± 2.3% versus -21.3 ± 2.1%, respectively; each P < 0.01), but there was no difference in the left ventricular ejection fraction between patients and controls (mean ± SD 63.5 ± 7.2% versus 64.6 ± 4.4%; P = 0.20). In patients with SSc, global longitudinal and circumferential strains each correlated with the peak VO(2) (r = -0.46 and r = -0.41, respectively; both P < 0.01), and multivariate analysis confirmed the independent association of each strain measure with the peak VO(2) . Compared to SSc patients with normal results on EKG Holter monitoring, SSc patients with abnormal results showed impaired global longitudinal strains (-18.5 ± 1.5% versus -17.1 ± 2.1%; P < 0.01) and circumferential strains (-18.7 ± 2.0% versus -17.3 ± 2.5%; P = 0.01), and each strain measure was independently associated with abnormal Holter findings. CONCLUSION Speckle-tracking strain analysis can detect subtle myocardial dysfunction in patients with SSc. Importantly, decreased global longitudinal and circumferential strains are associated with lower functional capacity and rhythm disturbances in patients with SSc.Pathogenesis and treatment of chronic pulmonary disease
