RESUMO

Nonbacterial thrombotic endocarditis (NBTE) is a rare finding, which is mostly associated with malignant diseases leading to hypercoagulability. We report the case of a severe quadruple valve nonbacterial thrombotic endocarditis in a patient with clear cell cervical cancer.

RESUMO

Background Regular exercise training represents an important modifier of arterial stiffness (AS). Therefore, sex-specific relations between domains of physical activity (PA; commuting, domestic, and leisure-time PA, including active sport and occupational PA) with AS were investigated. Methods and Results Stiffness index by digital photoplethysmography was investigated in 12 650 subjects from the GHS (Gutenberg Health Study). Self-reported PA was evaluated by the "Short Questionnaire to Assess Health-Enhancing Physical Activity" and reported as activity score peer week, being a combined measure of duration, frequency, and intensity of PA. Multivariable linear regression analysis demonstrated strong beneficial effects of repetitive activities, such as active commuting or leisure-time PA-related walking on AS in men, but not in women. Lower AS associated with endurance training was also found among men and premenopausal women. In contrast, intense occupational PA was related to stiffer vessels in men (P<0.0001) and women (P=0.0021) in a fully adjusted model. Combination of both, performing endurance training and having stiffness index values below median, resulted in the best survival. In contrast, subjects with elevated stiffness index at baseline without any endurance activities demonstrated the worst survival. Conclusions In this population representative sample, a differential impact of domains of self-reported PA on AS was demonstrated. Our data strengthen the importance of regular endurance PA to induce a reduction of AS, which, in turn, may improve cardiovascular prognosis. We also report deleterious effects of intense occupational PA on stiffness index, a finding that needs further confirmation by larger prospective trials.

RESUMO

Importance: Global longitudinal strain (GLS) is an emerging echocardiographic biomarker of cardiac function in heart failure (HF). Evidence from large-scale studies comprehensively investigating GLS for its association with clinical phenotypes and mortality in asymptomatic and symptomatic chronic HF is limited. Objective: To assess the factors associated with GLS and its prognostic value in patients with chronic HF. Design, Setting, and Participants: The observational, prospective MyoVasc cohort study enrolled 3289 individuals with asymptomatic to symptomatic HF between January 17, 2013, and April 27, 2018. The median follow-up was 3.2 years (interquartile range, 2.0-4.0 years). Participants with stages A to D HF according to American Heart Association (AHA) criteria were examined at a dedicated study center. Echocardiography was performed with GLS measurement by independent reviewers. Data were analyzed from September 2, 2019, to January 15, 2020. Main Outcomes and Measures: All-cause and cardiac mortality were recorded by structured follow-up and validated via death certificates. Results: In the study sample, data on GLS were available on 2440 individuals, of whom 2186 (mean [SD] age, 65.0 [10.5] years; 1418 [64.9%] men) were classified as having AHA HF stages A to D. Mean (SD) GLS worsened across AHA stages from stage A (n = 434; -19.44 [3.15%]) to stage B (n = 629; -18.01 [3.46%]) to stages C/D (n = 1123; -15.52 [4.64%]). Age (ß = -0.27; 95% CI, -0.47 to -0.067; per decade, P = .009), female sex (ß = -1.2; 95% CI, -1.6 to -0.77; per decade, P < .001), obesity (ß = 0.64; 95% CI, 0.25-1.0; P = .001), atrial fibrillation (ß = 1.2; 95% CI, 0.69-1.6; P < .001), myocardial infarction (ß = 1.5; 95% CI, 1.00-2.1; P < .001), and estimated glomerular filtration rate (ß = -0.53; 95% CI, -0.73 to -0.32; per SD, P < .001) were independently associated with GLS in multivariable regression analysis. Global longitudinal strain was associated with the severity of HF as reflected by N-terminal prohormone B-type natriuretic protein (NT-proBNP) levels after additionally adjusting for cardiac structure and function (P < .001). During follow-up, GLS was associated with all-cause mortality (hazard ratio [HR] per SD, 1.55; 95% CI, 1.19-2.01; P < .001) and cardiac death (HR per SD, 2.32; 95% CI, 1.57-3.42; P < .001) independent of image quality, observer variability, clinical profile, HF medications, NYHA class, and cardiac structure and function. After further adjustment for the NT-proBNP level, GLS remained associated with cardiac death (HR per SD, 1.60; 95% CI, 1.07-2.41; P = .02) but not all-cause mortality (HR per SD, 1.26; 95% CI, 0.95-1.66; P = .11). Conclusions and Relevance: In patients with chronic HF, GLS was associated with clinical and cardiac status, reflected neurohormonal activation, and was associated with cardiac mortality independent of clinical and cardiac status. These findings suggest that GLS may serve as a useful tool to improve risk stratification in patients with HF.

RESUMO

BACKGROUND: Experimental data indicate that direct acting oral anticoagulants (DOAC) and vitamin K antagonists (VKA) may exert differential effects on cardiovascular disease. METHODS: Data from the prospective, observational, single-center MyoVasc Study were used to examine associations of DOAC as compared to VKA with subclinical markers of cardiovascular disease, cardiac function, and humoral biomarkers in heart failure (HF). RESULTS: Multivariable analysis adjusted for age, sex, traditional cardiovascular risk factors, comorbidities, and medications with correction for multiple testing demonstrated that DOAC therapy was among all investigated parameters an independent significant predictor of better diastolic function (E/E': ß - 0.24 [- 0.36/- 0.12]; P < 0.0001) and higher levels of ApoA1 (ß + 0.11 g/L [0.036/0.18]; P = 0.0038) compared to VKA therapy. In propensity score-weighted analyses, the most pronounced differences between DOAC and VKA-based therapy were also observed for E/E' (∆ - 2.36) and ApoA1 (∆ + 0.06 g/L). Sensitivity analyses in more homogeneous subsamples of (i) individuals with AF and (ii) individuals with asymptomatic HF confirmed the consistency and robustness of these findings. In the comparison of factor IIa and Xa-directed oral anticoagulation, no differences were observed regarding cardiac function (E/E' ratio: ßIIa inhibitor - 0.22 [- 0.36/- 0.08] vs. ßXa inhibitor - 0.24 [- 0.37/- 0.11]) and lipid metabolism (ApoA1: ßIIa inhibitor 0.10 [0.01/0.18] vs. ßXa inhibitor 0.12 [0.04/0.20]) compared to VKA therapy. CONCLUSION: This study provides the first evidence for differential, non-conventional associations of oral anticoagulants on cardiac function and lipid metabolism in humans. The potentially beneficial effect of DOACs in the highly vulnerable population of HF individuals needs to be further elucidated and may have implications for individually tailored anticoagulation therapy.

RESUMO

Patients with heart failure (HF) are frequently anti-coagulated with vitamin K-antagonists (VKAs). The use of long-acting VKA may be preferable for HF patients due to higher stability of plasma concentrations. However, evidence on phenprocoumon-based oral anti-coagulation (OAC) therapy in HF is scarce. The aim of this study was to assess the impact of the presence of HF on quality of phenprocoumon-based OAC and the subsequent clinical outcome. Quality of OAC therapy and the incidence of adverse events were analysed in a cohort of regular care (n = 2,011) from the multi-centre thrombEVAL study program (NCT01809015) stratified by the presence of HF. To assess the modifiability of outcome, results were compared with data from individuals receiving specialized care for anti-coagulation (n = 760). Overall, the sample comprised of 813 individuals with HF and 1,160 subjects without HF in the regular care cohort. Quality of OAC assessed by time in therapeutic range (TTR) was 66.1% (47.8%/82.8%) for patients with HF and 70.6% (52.1%/85.9%) for those without HF (p = 0.0046). Stratification for New York Heart Classification (NYHA)-class demonstrated a lower TTR with higher NYHA classes: TTRNYHA-I 69.6% (49.4%/85.6%), TTRNYHA-II 66.5% (50.1%/82.9%) and TTRNYHA-≥III 61.8% (43.1%/79.9%). This translated into a worse net clinical benefit outcome for HF (hazard ratio [HR] 1.63 [1.31/2.02]; p < 0.0001) and an increased risk of bleeding (HR 1.40 [1.04/1.89]; p = 0.028). Management in a specialized coagulation service resulted in an improvement of all, TTR (∆+12.5% points), anti-coagulation-specific and non-specific outcome of HF individuals. In conclusion, HF is an independent risk factor for low quality of OAC therapy translating into an increased risk for adverse events, which can be mitigated by specialized care.
