Purpose: Interleukin (IL)-33 and its soluble receptor ST2 (sST2) play a crucial role in the immune response. sST2 has been approved by the Food and Drug Administration as a prognostic biomarker of mortality in chronic heart failure patients, however, the role of IL-33 and sST2 in atherosclerotic cardiovascular disease remains unclear. The aim of this study was to measure serum level of IL-33 and sST2 of patients at the onset of acute coronary syndrome (ACS) and 3 months after primary percutaneous revascularization.Patients and methods: Forty patients were divided into ST segment elevation myocardial infarction (STEMI) group, non-ST segment elevation myocardial infarction (NSTEMI) and unstable angina (UA) group. IL-33 and sST2 level were measured with ELISA. Additionally, IL-33 expression in peripheral blood mononuclear cells (PBMCs), was evaluated.Results: All ACS patients had a significantly lower level of sST2 3 months after ACS as compared to the baseline (p < 0.039). The STEMI patients had higher serum levels of IL-33 at the moment of ACS as compared to 3 months after the event, with an average decrease of 17.87 pg/ml (p < 0.007). Conversely, sST2 serum levels were still high after 3 months following an ACS in STEMI patients. ROC curve demonstrated that increased IL-33 serum level could be STEMI predictor.Conclusions: The assessment of the baseline and dynamics of changes in IL-33 and sST2 concentrations in patients with ACS may be important for the diagnostic process and may help in understanding of how the immune mechanisms work at the moment of an ACS event.
The clinical manifestations of COVID-19 which mainly involve the respiratory system may however affect also cardiovascular system. There are a lot and still increasing numbers of reports revealing cardiovascular complications of COVID-19, which may occur in the acute phase as well as during longer follow-up period. The most clinically important diseases include: pulmonary embolism (PE), myocarditis, and acute coronary syndromes (ACS) as well as arrhythmias with the very common atrial fibrillation (AF) and pericarditis. In this review, we present cardiac imaging options in patients with and after coronavirus infection, showing potential utility for expanding and improving the full and accurate diagnosis of potential complications. We considered echocardiography, magnetic resonance imaging, and computed tomography (CT) in turn, highlighting their best advantages in patients affected by COVID-19.
Mitral valve prolapse (MVP) is a relatively common mitral valvulopathy and the most common cause of isolated primary mitral regurgitation (MR) requiring surgical repair. It affects about 1–3% of the general population. Although MVP is viewed as a benign condition, the association between MVP and sudden cardiac death (SCD) has been proven. Patients with MVP have a three times higher risk of SCD than the general population. The underlying mechanisms and predictors of arrhythmias, which occur in patients with MVP, are still poorly understood. However, some echocardiographic features such as mitral annulus disjunction (MAD), bileaflet MVP (biMVP), and papillary muscle (PM) fibrosis were frequently linked with increased number of arrhythmic events and are referred to as “arrhythmogenic” or “malignant”. Arrhythmogenic MVP (AMVP) has also been associated with other factors such as female sex, polymorphic premature ventricular contraction (PVC), abnormalities of T-waves, and Pickelhaube sign on tissue Doppler tracing of the lateral part of the mitral annulus. Cardiac magnetic resonance (CMR) imaging and speckle tracking echocardiography are new tools showing significant potential for detection of malignant features of AMVP. This paper presents various data coming from electrocardiography (ECG) analysis, echocardiography, and other imaging techniques as well as compilation of the recent studies on the subject of MVP.

Abstract Background Hypertrophic cardiomyopathy (HCM), being characterized by enhanced contractility, positively responses to treatment with myosin inhibitors which could promote reverse remodelling. Additionally, speckle tracking analysis highlights left ventricular (LV) contractile alterations in HCM, although the pathophysiological meaning and the effect of the target-therapy are still unclear. Aim To analyse global and regional longitudinal peak systolic strain in patients with HCM in comparison to age-matched control group without HCM and with known coronary artery anatomy. Methods We examined 37 HCM patients (33 with asymmetric septal and 4 with apical hypertrophy) and 67 age-matched controls without HCM or significant coronary stenoses, with transthoracic echocardiography with analysis of segmental and global left ventricular strain (GLS) by AFI method in 16-segment LV model. Results Patients with HCM showed higher values of interventricular septal thickness, left atrial diameter and LV ejection fraction, whereas controls presented higher BMI and resting heart rate. In deformation analysis, GLS values were lower in HCM (15.9 ± 4.2 vs 18.4 ± 3.5%, p = 0.002) as well as segmental strain was significantly impaired in marker regions for studied form of HCM, in particular septal, inferior and inferolateral basal and mid segments as well as apical inferior segment for HCM with asymmetric septal hypertrophy; 4 patients with apical form of HCM showed severely impaired strain in all apical segments. Conclusions Deformation analysis shows a significant impairment of global and segmental strain values in patients with HCM, in particular for hypertrophic segments. This finding does not definitely imply a certain contractile dysfunction, and further investigation on the effect of myosin inhibitors on strain analysis is strongly recommended.
Introduction: Atherosclerosis leading to coronary artery disease (CAD) is a chronic inflammatory condition. Interleukin 35 (IL-35) released by regulatory T cells (Tregs) has been found to be associated with CAD in the Chinese population. However, nothing is known about the relation between IL-35 concentrations and cholesterol levels. The aim of the study was to assess the levels of IL-35 in CAD patients and healthy subjects from a Caucasian population, and to analyze the relationship between IL-35 and the levels of total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, left ventricular ejection fraction (LVEF), sex and postmenopausal status. Material and methods: Thirty-one patients with CAD and 30 healthy controls were included in the study. Levels of plasma IL-35 were analyzed by ELISA. The LVEF was assessed by transthoracic echocardiographic examination. Plasma levels of cholesterol fractions and C-reactive protein (CRP) were assessed by immunoenzymatic methods. Results: The CAD patients had higher levels of IL-35 as compared to healthy controls (58.1 +/- 16.6 pg/ml vs. 5.35 +/- 3.35 pg/ml; p < 0.001). IL-35 levels negatively correlated with total and LDL cholesterol concentrations (R = -0.31, p < 0.01) and positively correlated with HDL cholesterol in men (R = 0.53, p < 0.01). In women, IL-35 levels negatively correlated with LVEF (R = -0.29, p < 0.05) and positively with the duration of postmenopausal status (R = 0.55, p < 0.01). Conclusions: These results suggest a possible association between high levels of IL-35 and CAD.
Atrial fibrillation (AF) and obesity is a growing problem of public health both in Poland and in the whole world. AF risk factors may be summarized as elderliness, male sex, smoking, hypertension, diabetes, obesity, coronary heart disease, heart failure, valvular heart disease, cardiac surgery. Once obesity is an independent, potentially modifiable risk factor for AF. The connection between obesity and atrial fibrillation is very up-to-date because of incremental prevalence, almost epidemic of obesity in the whole world. The probability of AF among obese patients increases with concomitant obstructive sleep apnea. Regardless many researches it hasn't been assessed yet how obesity itself predisposes to AF. It could be an effect of change in the atrial anatomy, the rise of atrial pressure, mechanical stretch, interstitial atrial fibrosis and disruption of atrial electric integrity. A great role is ascribed to inflammation, especially proinflammatory cytokines increased by adipocites of left atrial epicardial adiposity.
UNLABELLED:For 60 years, vitamin K antagonists have been used in prevention of thromboembolic complications in the course of atrial fibrillation (AF), however such therapy is associated with many inconveniences. New oral anticoagulants (NOAC), rivaroxaban and dabigatran, represent an attractive alternative to VKA.THE AIM OF THE STUDY:Yo evaluate the safety of a 6-month therapy with rivaroxaban and dabigatran in patients (pts) with persistent AF.MATERIALS AND METHODS:The analysis included 24 pts (14 females, 10 males) with nonvalvular AF and indications for oral anticoagulant therapy (CHA2DS2-VASc > or = 2, HAS-BLED < 3), hospitalized in the Clinic of Internal Diseases and Clinical Pharmacology of the Medical University of Lodz between July 2012 and September 2013. In the group of patients treated chronically with VKA, laboratory tests (GFR, creatinine, ALT AST, coagulation) were performed during their stay in the clinic. The patients were randomly assigned to the treatment with one of the new NOACs, rivaroxaban or dabigatran. After a 6-month period, the patients completed a questionnaire on their general health condition and follow-up laboratory tests were performed.RESULTS:In the group of pts. receiving dabigatran INR increased by 23% (p = 0.0002) and APTT prolongation by 91% was noted (p = 0.0004) whereas in the group of pts receiving rivaroxaban an INR increase by 17% (p = 0.04) and APTT prolongation by 32% (p = 0.0043) were observed. After a 6-month therapy, dabigatran prolongs APTT significantly more, as compared to rivaroxaban (p=0.0002). Among patients using dabigatran, 16.7% experienced the following symptoms: abdominal pain, gastritis, nausea. 8.3% patients experienced bleeding from haemorrhoids, easier bruising. In the group of patients receiving rivaroxaban, 16.7% experienced the following symptoms: nosebleeds and easier bruising; 8.3%: bleeding from gums, haematuria. 25%: pruritus, rash: 8.3%. The hazard ratio (HR) for occurrence of dyspeptic symptoms was 1.13 for dabigatran. Minor bleeding is 3.6 times more common when using rivaroxaban.CONCLUSIONS:Significant increase of INR and prolongation of APTT are observed after a 6-month therapy with rivaroxaban or dabigatran. Additionally, dabigatran significantly prolongs the prothrombin time. Despite the fact that dabigatran caused larger prolongation of APTT minor bleeding episodes occurred more frequently in patients treated with rivaroxaban. No worsening of kidney or liver function was observed during the 6-month therapy with rivaroxaban or dabigatran. Rywaroxaban more frequently causes minor bleeding, whereas treatment with dabigatran is associated with more frequent gastrointestinal adverse symptoms.
