    Abstract A 65 years old men with mechanical mitral prosthesis (implanted for rheumatic valve disease) was referred to our clinic with signs of advanced heart failure and associated severe dysphagia. This symptom started a couple of years before and became worsened in the last months causing severe difficulties in alimentation, both for solid and liquid foods. Echocardiography revealed a normofunctional mitral prosthesis, a dilated left ventricle with severe systolic dysfunction (EF 15%) and a giant left atrium (A-parasternal long axis view, left atrial postero-anterior diameter = 80mm, B-apical four chamber view, left atrial longitudinal diameter = 105mm). The X-ray examination with barium of the upper gastrointestinal tract demonstrated significant lumen reduction in the middle and lower part of the esophagus (C), corresponding to the external compression caused by the huge left atrium. The explanations for the severely enlarged left atrium would be the late valvular intervention (also suggested by the dilated and dysfunctional left ventricle) and the progression of left atrial remodeling due to chronic inflammation. The patient was referred to esophageal balloon dilation and stent implantation.

    Abstract Prediction and early detection of atrial fibrillation (AF) remain a permanent challenge in everyday practice. Timely identification of an increased risk for AF episodes (which are frequently asymptomatic) is essential in the primary and secondary prevention of cardioembolic events. One of the noninvasive modalities of AF prediction is represented by the electrocardiographic P-wave analysis. This includes the study and diagnosis of interatrial conduction block (Bachmann’s bundle block). Bayés’ Syndrome (named after its first descriptor) denotes the association between interatrial conduction defect and supraventricular arrhythmias (mainly AF) predisposing to cardioembolic events. Our short review presents an update of the most important data concerning this syndrome: brief history, main ECG features, pathophysiological background and clinical implications.

    Abstract Inflammation has emerged as an important contributor to heart failure (HF) development and progression. Current research data highlight the diversity of immune cells, proteins, and signaling pathways involved in the pathogenesis and perpetuation of heart failure. Chronic inflammation is a major cardiovascular risk factor. Proinflammatory signaling molecules in HF initiate vicious cycles altering mitochondrial function and perturbing calcium homeostasis, therefore affecting myocardial contractility. Specific anti-inflammatory treatment represents a novel approach to prevent and slow HF progression. This review provides an update on the putative roles of inflammatory mediators involved in heart failure (tumor necrosis factor-alpha; interleukin 1, 6, 17, 18, 33) and currently available biological and non-biological therapy options targeting the aforementioned mediators and signaling pathways. We also highlight new treatment approaches based on the latest clinical and experimental research.

    Abstract A 57-year-old non-obese female patient with a history of heavy smoking, chronic obstructive pulmonary disease and hypertension was admitted to the hospital as an emergency for acute hemoptysis and signs of congestive heart failure. To assess the source of hemoptysis, computed tomography (CT) pulmonary angiography was performed, which confirmed a bilateral pulmonary embolism of the apical branches. The routinely performed transthoracic echocardiography (TTE) revealed an enlarged left ventricle with severely reduced ejection fraction (EF = 25%) due to global hypokinesia and multiple, mobile, echogenic masses. To increase the diagnostic accuracy, real-time three-dimensional (Live 3D) imaging of the masses was added which described multiple left ventricular (LV) thrombi. Successful resolution of intraventricular thrombi was noticed after treatment with oral anticoagulant therapy (acenocumarol), despite the lack of regular INR control.

    Abstract Cor triatriatum sinister is a rare congenital heart disease characterized by an additional fibromuscular membrane in the left atrium. Cardioembolic stroke is a rare complication of cor triatriatum sinister, especially among women. We hereby describe the case of an 18-year-old female patient, without a past medical history, presenting with cardioembolic stroke in the territory of the right posterior cerebral artery. During extensive diagnostic work-up, nonrestrictive cor triatriatum sinister and patent foramen ovale were diagnosed using transthoracic and transesophageal echocardiography. In clinical practice, it is important to identify congenital cardiac defects as potential substrates for cardioembolism in young patients. In our case, cor triatriatum sinister presenting as ischemic stroke was diagnosed, which is an uncommon finding, especially in young females. Determining the optimal management strategy for patients with cor triatriatum sinister complicated by cardioembolic stroke requires a multidisciplinary approach.

    Abstract Peripheral arterial disease (PAD) is frequently associated with atherosclerotic manifestations of the carotids and coronaries. Polyvascular involvement and low ankle–brachial index predict major cardiovascular events and high mortality. Cathepsin S (Cat S) promotes the inflammatory pathways of the arterial wall, while Cystatin C (Cys C) functions as its inhibitor; therefore, Cys C was proposed to be a biomarker of progression in PAD. In a single-center observational study, we investigated the correlations of serum Cys C and Cat S/Cys C ratio in a group of 90 PAD patients, predominantly with polyvascular involvement. Cys C and Cat S/Cys C were associated with ankle–brachial index (ABI) scores <0.4 in univariate and multiple regression models. Furthermore, both markers correlated positively with the plasma Von Willebrand Factor Antigen (VWF: Ag) and Von Willebrand Factor collagen-binding activity (VWF: CB). In addition, Cat S/Cys C was significantly decreased, whereas Cys C increased in subjects with three-bed atherosclerotic involvement. According to our results, high serum Cys C and low Cat S/Cys C ratios may indicate severe peripheral arterial disease and polyvascular atherosclerotic involvement.

    Abstract Arterial stiffness (AS) is a complex vascular phenomenon with consequences for central hemodynamics and left-ventricular performance. Circulating biomarkers have been associated with AS; however, their value in heart failure is poorly characterized. Our aim was to evaluate the clinical and biomarker correlates of AS in the setting of heart failure with reduced ejection fraction (HFrEF). In 78 hospitalized, hemodynamically stable patients (20 women, 58 men, mean age 65.8 ± 1.41 years) with HFrEF, AS was measured using aortic pulse wave velocity (PWV). Serum OPG, RANKL, sclerostin, and DKK-1 were determined, and the relationships between the clinical variables, vascular-calcification-related biomarkers, and PWV were evaluated by correlation analysis and linear and logistic regression models. OPG and the OPG/RANKL ratio were significantly higher in the group of patients ( n = 37, 47.4%) with increased PWV (>10 m/s). PWV was positively correlated with age, left-ventricular ejection fraction, and carotid intima-media thickness (cIMT), and negatively correlated with the glomerular filtration rate. OPG and cIMT were significantly associated with PWV in the logistic regression models when adjusted for hypertension, EF, and the presence of atherosclerotic manifestations. Elevated serum OPG, together with cIMT, were significantly related to increased AS in the setting of HFrEF.

    Abstract Abstract: In a cohort of patients hospitalized with acute heart failure (AHF) the prevalence of anemia and the existence of a correlation between anemia and the severity of the clinical picture were assessed. Methods: 50 consecutive patients (34 men, 16 women, mean age 67.5 years) hospitalized with AHF were enrolled. Statistical analysis was performed for studying correlations between anemia and the presence/levels of diverse parameters (clinical, laboratory, echocardiographic, treatment related) reflecting the severity and prognosis of AHF (α=0.05). Results: 21 patients (14 men, 7 women, mean age 69.6 years), representing 42%, had anemia at admission. Comparing patients with and without anemia there were no significant differences regarding age, gender, presence of atrial fibrillation (p=0.75), diabetes (p=1), ischemic heart disease (p=0.9), left ventricular ejection fraction (EF) (p=1), hypotension (p=0.34) and tachycardia>100 b/min at admission (p=0.75), level of eGFR (p=0.72), and need of high dose (>80 mg/day) loop diuretic (p=0.23). However, EF showed a significant positive correlation with eGFR only in AHF patients with anemia (r=0,65, p=0.001). In a multiple regression model, EF had a significant effect on the eGFR quartiles (p=0,004). Conclusions: Anemia is a frequent finding in patients hospitalized with AHF. The presence of anemia was not correlated with other factors related to AHF severity and prognosis. However, a low EF associated with low eGFR was characteristic for patients with anemia, suggesting that the decrease of renal perfusion by low cardiac output further aggravates anemia on the background of chronic kidney disease.

    Abstract Objective. The possible effect of blood pressure measurements per se on heart rate variability (HRV) was studied in the setting of concomitant ambulatory blood pressure monitoring (ABPM) and Holter ECG monitoring (HM). Methods. In 25 hypertensive patients (14 women and 11 men, mean age: 58.1 years), 24-hour combined ABPM and HM were performed. For every blood pressure measurement, 2-minute ECG segments (before, during, and after measurement) were analyzed to obtain time domain parameters of HRV: SDNN and rMSSD. Mean of normal RR intervals (MNN), SDNN/MNN, and rMSSD/MNN were calculated, too. Parameter variations related to blood pressure measurements were analyzed using one-way ANOVA with multiple comparisons. Results. 2281 measurements (1518 during the day and 763 during the night) were included in the analysis. Both SDNN and SDNN/MNN had a constant (the same for 24-hour, daytime, and nighttime values) and significant change related to blood pressure measurements: an increase during measurements and a decrease after them (p<0.01 for any variation). Conclusion. In the setting of combined ABPM and HM, the blood pressure measurement itself produces an increase in short-term heart rate variability. Clarifying the physiological basis and the possible clinical value of this phenomenon needs further studies.
