Cardiovascular diseases, and in particular coronary artery disease (CAD), are the leading causes of death in Europe and represent around 50% of overall mortality. Numerous cardiovascular markers have been proposed in relation to cardiovascular risk prediction, in relation to cardiac and vascular and cerebral events. Chemokines which regulate immune cell vascular chemotaxis, including CCL5/RANTES are points of great interest. We hypothesized that chemokine RANTES level measured in peripheral blood may be associated with severity of atherosclerosis in patients with stable angina undergoing coronary angiography. RANTES and interleukin 18 (IL-18) levels were measured by ELISA. Classical and novel cardiovascular risk factors like brachial flow mediated dilation and intima-media thickness were analyzed in the context of chemokine levels and severity of atherosclerosis. Study included 62 consecutive patients with coronary atherosclerosis demonstrated by coronary angiography, (mean age 59.3 years (S.D. = 7.4)), divided into two groups: group I with lower severity of atherosclerosis, (n = 45) and group 2 with severe CAD (n = 17) based on coronary angiography. Groups were well balanced for classic risk factors for atherosclerosis. Mean RANTES level were significantly higher in patients in group I (67.9 ng/ml, S.E.M. = 3.97) than in group II (50.5 ng/ml, S.E.M. = 7.49; P = 0.03). In contrast, IL-18 levels were similar in both groups (255 pg/ml in group I and 315 pg/ml, S.E.M. = 40.91 in group I, P = 0.12), as well as hsCRP concentration (3.45 S.E.M. = 2.66 ng/ml and 4.69 ng/ml S.E.M.= 1.64 ng/ml respectively; P = 0.47). Flow-mediated dilatation (FMD) values have been significantly lower in group II than in group I (6.31; S.E.M. = 0.61; vs 4.41; S.E.M. = 0,56, respectively, P = 0.026), while nitroglycerine-mediated dilatation (NMD) did not differ, indicating more pronounced endothelial dysfunction. No significant correlations between chemokine RANTES levels and intima-media thickness (IMT), FMD measurements have been found in the total population studied. Chemokine RANTES level could become a useful marker of severity of coronary artery disease. Its lower levels were observed in patients with more diffuse disease. Elevated level of chemokine RANTES in patients with stable angina pectoris may evaluate patients to high risk group in plaque formation at early stages of atherosclerosis.

- Abstract
An increased risk of atherosclerotic and thrombotic complications characterizes connective tissue diseases. Endothelial dysfunction is the basis for the initiation and progression of atherosclerosis and thrombosis. We present systemic lupus erythematosus (SLE) as a model rheumatic disease with endothelial dysfunction and discuss its mechanisms, factors that influence the early onset and rapid progression of atherosclerosis, and the increased risk of thromboembolic events. We focus on established methods to improve endothelium function, including statins, antiplatelet, and antithrombotic therapy. Hypercoagulable and hypofibrinolitic states and a hyperinflammatory response characterize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Several pathogenic mechanisms are typical for an acute phase of Covid-19 post-Covid syndrome and connective tissue diseases: endothelial dysfunction, elevated antiphospholipid antibody titer, activation of the complement system, and formation of extracellular neutrophil traps (NET). The current review discusses the mechanisms underlying SLE and the COVID-19 in the context of endothelial function, atherosclerosis, and thrombosis (Graphical abstract). Key Points • The pathophysiology of systemic lupus erythematosus (SLE) and Covid-19 shows some similarities, such as endothelial cell activation and dysfunction, the activation of complementary systems, the presence of antiphospholipid antibodies, and the formation of extracellular neutrophil traps. • Autoimmunity in both diseases creates the basis for hyperinflammatory, hypercoagulable, and hypofibrinolitic states and their thromboembolic complications. • This paper presents our perspective on the mechanisms behind the cardiovascular manifestations of SLE and COVID-19, with a particular emphasis on endothelial dysfunction. Covid-19 and systemic lupus erythematosus-potential similarities in pathophysiology. Figures of the panel illustrate the clinical manifestations of endothelial dysfunction, atherosclerosis, and thromboembolism, including coronary artery disease ([A] coronary angiography with left anterior descending artery stenosis and [B] scintigraphy with reduced perfusion in the myocardial apical segments), stroke ([C] carotid angiography, left carotid artery occlusion) and pulmonary embolism ([D]computed tomography with thrombus in the right pulmonary artery)., (© 2023.

- Abstract
Background: Previous studies on animal models have suggested that δ-opioid receptor (OR) signaling is the primary pathway responsible for opioids' cardioprotective effect. We hypothesize that the μ-OR's activation protects the human heart muscle., Methods: We performed the experiments on muscular trabeculae obtained from the right atrial appendages of 104 consecutive patients subjected to coronary artery bypass surgery. Two trabeculae from each patient were studied simultaneously and exposed to 60 min of hypoxia with subsequent 60 min of reoxygenation. Remifentanil (5 μM or 50 μM) or sufentanil (40 μM or 400 μM) was used from the time of reoxygenation. Trabeculae contractility was assessed as the maximal amplitude of the contraction at baseline, after 60 min of hypoxia, during reoxygenation, and after norepinephrine application., Results: During reperfusion, the application of remifentanil improved cardiomyocytes' function as compared to the control group (time from reperfusion: 15 min: 39.8% vs. 21.7%, p = 0.01; 30 min: 41.4% vs. 21.8%, p = 0.01; 60 min: 42.7% vs. 26.9%, p = 0.04; after norepinephrine: 64.7% vs. 43.2%, p = 0.03). The application of sufentanil did not influence cardiomyocyte function as can be seen when comparing the results of the experimental and control group., Conclusions: Remifentanil, but not sufentanil, induces a cardioprotective effect on human right atria muscle in in vitro conditions, manifested as the increased amplitude of their contraction during reperfusion after 60 min of ischemia., (© 2023.

- Abstract
Introduction: Recent analysis from CHART-1 study indicated that the therapeutic effects of trans-endocardial cardiopoetic cell transplantation in chronic ischemic heart failure (iCHF) may be lost with an increasing number of injections perfomed to deliver therapeutic cells., Aim: To evaluate global and regional contractility and diastolic function of the left ventricle of patients with iCHF who received trans-endomyocardial cardiopoietic stem cells (CSCs) delivery or sham procedures., Material and Methods: The study included patients (mean age: 60.8 ±7.1 years) with iCHF (left ventricular ejection fraction (LVEF) < 35%) and a history of hospitalization for worsening heart failure within 12 months despite optimal medical therapy. The patients underwent transmyocardial CSCs transplantation using perforated needle technique or a sham procedure. The wall motion score index (WMSI), LVEF, transmitral E-velocity, E-wave deceleration time, E/A-ratio, and E/e'-mean value were measured with two-dimensional echocardiography on days 1 and 30., Results: A total of 170 segments were analyzed, including 48 targeted segments where 92 injections of 0.5 ml of CSCs were performed. In the transendocardial injections cohort, a decrease in regional contractility was observed in 30.6% (26/85) and 18.9% (16/85) of the segments on days 1 and 30, respectively. This was accompanied by an increase in WMSI by 0.32 ±0.06 and 0.19 ±0.18 (day 1, p = 0.02, day 30, p = 0.03) and a reduction in LVEF (-3.15 ±1.23%, p = 0.065)., Conclusions: Transendocardial injections performed to deliver therapeutic cells were associated with myocardial injury. This adverse effect remained, albeit at a lesser degree, at 30-days. Mechanical injury with trans-endocardial delivery of progenitor cells using the "needle technique" may counterbalance, at least in part, any cell-related benefit(s)., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia Sp. z o. o.)

- Abstract
Acute decompensated heart failure (ADHF) treatment leads to significant hemodynamic changes. The aim of our study was to quantitatively analyze the dynamics of mitral regurgitation (MR) severity (evaluated by transthoracic echocardiography) which occur during the treatment of ADHF and to correlate these changes with the clinical condition of patients as well as heart failure biochemical markers. The study included 27 consecutive adult patients (40.7% females, mean age 71.19 ± 11.2 years) who required hospitalization due to signs of acute HF. Echocardiographic assessment was performed upon admission and discharge together with clinical and laboratory evaluation. Significant reduction in dyspnea intensity [0-100 scale] (81.48 ± 9.07 vs. 45.00 ± 11.04 pts, p < 0.001), body weight (84.98 ± 18.52 vs. 79.77 ± 17.49 kg, p < 0.001), and NT-proBNP level (7520.56 ± 5288.62 vs. 4949.88 ± 3687.86 pg/ml, p = 0.001) was found. The severity of MR parameters decreased significantly (MR volume 44.92 ± 22.83 vs. 30.88 ± 18.77 ml, p < 0.001; EROA 0.37 ± 0.17 vs. 0.25 ± 0.16 cm
2 , p < 0.001; VC 6.21 ± 1.48 vs. 5.26 ± 1.61 mm, p < 0.001). Left atrial area (35.86 ± 9.11 vs. 32.47 ± 9.37, p < 0.001) and mitral annular diameter (42.33 ± 6.63 vs. 39.72 ± 5.05. p < 0.001) also underwent statistically significant reductions. An increase in LVEF was observed (34.73 ± 13.88 vs. 40.24 ± 13.19%, p < 0.001). In 40.7% of patients, a change in MR severity class (transition from a higher class to a lower one) was observed: 6/8 (75%) patients transitioned from severe to moderate and 6/18 (33.3%) patients transitioned from moderate to mild class. Treatment of ADHF leads to a significant reduction in MR severity, together with significant reductions in left atrial and mitral annular dimensions. Quantitative measurement of MR dynamics offer valuable assistance for ADHF management., (© 2021. The Author(s).)- Published

- Abstract
Purpose: Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for cardiovascular diseases. The aim of the study was to assess the influence of OSAS on endothelial dysfunction and thrombosis biomarkers and to evaluate the effect of treatment with continuous positive airway pressure (CPAP) on biomarker levels., Methods: NT-proBNP, sICAM-1, endothelin-1, von Willebrand factor, D-dimers, and thrombin-antithrombin complex (TAT) were measured in 50 patients diagnosed with moderate-to-severe OSAS. All patients underwent transthoracic echocardiography, and 38 months after the inclusion, 16 CPAP users and 22 non-CPAP users were reassessed., Results: Sleep-related indices of apnea-hypopnea index (AHI) and mean SpO
2 were associated with higher sICAM-1 levels (AHI < 30: 7.3 ± 4.7 vs. AHI ≥ 30: 19.5 ± 19.4 mg/ml, p = 0.04; SpO2 ≥ 90%: 11.9 ± 9.3 vs. SpO2 < 90%: 23.6 ± 25.8, p = 0.04). sICAM-1 levels were significantly higher in obese patients, particularly with BMI ≥ 40. Plasma levels of TAT were significantly correlated with the increased right ventricular size (right ventricular diameter ≤ 37 mm: 0.86 ± 0.70 vs. > 37 mm: 1.96 ± 1.20 ng/ml, p = 0.04). Endothelin-1 levels were higher in patients with decreased right ventricular function (right ventricle TDI-derived S' ≥ 12 cm/s: 11.5 ± 10.9 vs. < 12 cm/s: 26.0 ± 13.2 pg/ml, p = 0.04). An increase in NT-proBNP was related to impaired parameters of the right ventricular contractile function. There were no correlations between long-term CPAP therapy and the levels of biomarkers., Conclusion: Severe OSAS influences endothelial damage as manifested by an increase in sICAM-1 levels. Changes in right ventricular structure and function, observed mainly in patients with higher TAT and endothelin-1 levels, are also manifested by an increase in NT-proBNP levels. Long-term CPAP treatment does not seem to influence biomarkers in patients with moderate-to-severe OSAS, which may help to explain the lack of influence of CPAP on cardiovascular risk reduction., (© 2021.

- Abstract
Introduction: Systemic lupus erythematosus (SLE) is characterized by early atherothrombosis. Pulse wave velocity (PWV) is a promising tool for the diagnosis of early vascular remodelling and initial atherosclerotic plaque formation. Our objective was to evaluate PWV and its relationship with coronary atherosclerosis and thrombotic biomarkers in patients with SLE., Material and Methods: In 26 patients with SLE with stable clinical conditions, mean age of 39.1 ±11.7 years and without a history of coronary artery disease, multidetector computed tomography (MDCT)-based coronary calcium scoring (CACS) was performed and PWV measured.Laboratory evaluation included serum levels of anticardiolipin and anti-β2-glycoprotein antibodies (anti-β2-GPI), lupus anticoagulant (LA), D-dimers, thrombin-antithrombin complexes (TAT), and von Willebrand factor (vWF)., Results: Multidetector computed tomography revealed coronary calcifications in 8 (30.8%) patients and the median CACS was 52.4 HU (range 2-843.2). The mean PWV was 9.0 ±3.2 m/s and was higher in patients aged > 50 years (+33.7% vs. < 50 years), those with positive LA (+28.2% vs. LA negative), TAT ≥ 10 μg/l (+18.1% vs. < 10 μg/l), vWF ≥ 200 IU/dl (+51.8% vs. < 200 IU/dl) and with coronary atherosclerosis (CACS > 0; +21.4% vs. CACS = 0).In contrast, the duration of the disease, D-dimers, anticardiolipin, and anti-β2-GPI antibodies did not influence PWV. In the group without atherosclerosis (CACS = 0, n =18), patients with vWF ≥ 200 IU/dl had a 19.3% higher PWV compared to the rest., Conclusions: In patients with SLE, PWV was associated with the presence of coronary atherosclerotic lesions in MDCT. Furthermore, arterial stiffness was higher in patients with markers of endothelial dysfunction and a prothrombotic state, suggesting their contribution to the early stages of arterial remodelling in SLE., Competing Interests: The authors declare no conflicts of interest.

- Abstract
Obstructive sleep apnea syndrome (OSAS) is considered to be an important predisposing factor for cardiovascular diseases. The main objective of this study was to investigate the impact of CPAP treatment on cardiac structure and function and to assess patient compliance over a long-term course of CPAP treatment. A total of 50 patients diagnosed with moderate-to-severe OSAS based on overnight study, without relevant concomitant diseases were enrolled. Patient compliance, along with echocardiographic and CPAP parameters, was assessed. The average time to follow-up was 38 ± 4.2 months. An increase in tricuspid annular plane systolic excursion (TAPSE) (22.1 ± 4.3-25.5 ± 4.6 mm, p = 0.005) and peak early systolic tricuspid annular velocity (S') (14 ± 3.2-17.2 ± 5.2 cm/s, p = 0.005) after CPAP treatment was noted. In patients without CPAP, no significant change in right ventricular (RV) contractility was found. There were no significant differences regarding right atrial (RA) and RV diameters, as well as tricuspid regurgitant peak gradient (TRPG) in both groups; however, a predisposition to increased RA size along with RV and tricuspid annulus diameters was revealed. The mean duration of nightly CPAP use was 3 ± 2.3 h/night in all-day analysis and 4.7 ± 2.1 h/night on days with device usage. The non-adherence rate was 57%. The use of effective CPAP therapy may lead to increased RV systolic function in patients with OSAS in long-term observation. However, long-term patient compliance is generally poor. Regardless of CPAP therapy, a gradual increase in heart size is observed., Competing Interests: Conflicts of interestThe authors declare that there is no conflict of interest., (© The Author(s) 2021.)

- Abstract
Background: Although patients undergoing the Fontan procedure (FP) present a normal or close‑to‑‑normal function of the systemic ventricle, they cannot generate cardiac output or exhibit similar exercise capacity as their healthy peers. This can be attributed to chronotropic incompetence and multiple organ complications., Aims: We evaluated the prevalence of chronotropic incompetence in adults after FP and assessed the relationship between heart rate reserve (HRR) and multiple organ complications., Methods: Data were obtained from 50 post‑FP patients (mean [SD] age, 27 [6.6] years) and 30 healthy controls matched for age and sex. All patients were subjected to clinical examination, laboratory tests, echocardiography, cardiopulmonary exercise test, and chronotropic function evaluation., Results: Cardiopulmonary exercise test parameters were impaired in the post‑FP group. Chronotropic incompetence was identified in 46 patients (92%), who also had a lower median (interquartile range) chronotropic index (0.55 [0.47-0.62] vs 0.93 [0.88-0.99]; P <0.001) and a greater median (interquartile range) HRR (32 [24-60] bpm vs 8 [1-14] bpm, P <0.001). A negative correlation was observed between HRR and peak oxygen uptake, and a positive one between HRR and the peak ventilatory equivalent for CO2 and mean platelet volume. The study revealed the diagnostic utility of HRR in detecting an abnormal peak ventilatory equivalent for O2, alkaline phosphatase levels, the ratio of aspartate transaminase to alanine transaminase levels, and mean platelet volume., Conclusions: Chronotropic incompetence correlates with impaired exercise capacity, liver dysfunction, and platelet abnormalities in post‑FP patients. Heart rate reserve may be a promising indicator of organ complications as well as a sign of future bradyarrhythmia and the need for cardiac pacing.

- Abstract
Introduction: Obstructive sleep apnea syndrome (OSAS) is a highly prevalent sleep disorder associated with increased cardiovascular morbidity and mortality. This study aimed to investigate heart structure and function and their correlation with the degree of OSAS and sleep indexes in patients diagnosed with OSAS., Materials and Methods: A cohort of 77patients (48 males, aged 58.1 ± 11.0 years, body mass index [BMI] = 32.4 ± 6.2) admitted to the hospital due to suspected OSAS was examined using echocardiography and polysomnography., Results: Patients with moderate-to-severe OSAS compared to patients without diagnosed OSAS or with mild OSAS had greater right ventricular outflow tract (RVOT) dimensions (32.6 ± 3.6 vs 30.9 ± 2.4 mm; p < 0.05), larger right atrial area (RAA; 21.1 ± 4.8 vs 17.2 ± 3.2 mm; p = 0.002), greater right ventricular mid-cavity diameter (RVD; 35.5 ± 7.0 vs 32.2 ± 4.7 mm; p = 0.02), and diminished tricuspid annular plane systolic excursion (TAPSE, 21.9 ± 4.5 vs 25.8 ± 4.4 mm; p = 0.04), while there were no significant differences in tissue doppler imaging (TDI) parameters (S' and E') and in valvular regurgitation gradient for both groups. Moreover, significantly greater RVOT dimensions (31.6 ± 2.6 vs 30.9 ± 3.0 mm, p = 0.04), RVD (39.3 ± 7.0 vs 32.7 ± 5.2 mm, p = 0.003), and RAA (21.4 ± 4.4 vs 18.1 ± 4.2 mm, p = 0.02) as well as reduction in TAPSE (20.9 ± 5.3 vs 25.0 ± 4.3 mm, p = 0.01) were observed in patients having ≥ 10 episodes of obstructive apnea (OA) per hour., Conclusions: In moderate-to-severe OSAS patients, right ventricular (RV) enlargement was observed together with RV dysfunction as measured by TAPSE. Examination using TDI is not superior to standard echocardiography for the detection of heart pathology in OSAS patients. Right heart pathology is present predominantly in patients with obstructive apnea.

- Abstract
Introduction: Metabolic alterations have been recently associated with onset and progression of idiopathic pulmonary arterial hypertension (IPAH). We aimed to determine the prevalence and prognostic role of cardiovascular risk factors in patients with IPAH., Material and Methods: Between February 2009 and January 2015 we recruited consecutive IPAH patients. Clinical assessment included medical history, fasting glucose, lipid profile, N-terminal pro-brain natriuretic peptide concentration, 6-minute walk test distance, WHO functional class and hemodynamic evaluation. Patients' risk was estimated based on the Swedish PAH Register grading system., Results: The study group included 61 IPAH patients, and the control group included 2413 Polish residents. When compared to the general population, IPAH patients had lower low-density lipoprotein cholesterol (LDL-C) and a higher triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio. Female patients were characterized by elevated glucose level, higher prevalence of diabetes and lower HDL-C than controls. PAH severity grade correlated positively with age and TG/HDL-C ratio ( R = 0.29, p = 0.02) and inversely with LDL-C ( R = -0.28, p = 0.03) and HDL-C ( R = -0.39, p = 0.02) concentrations. After a follow-up of 48 (23-79) months we recorded 28 deaths in the IPAH group. In the regression analysis lower LDL-C ( p = 0.002) and HDL-C ( p = 0.0002) levels, and higher TG/HDL-C ratio ( p = 0.003) and glucose level ( p = 0.003) were associated with all-cause mortality after adjustment for age, sex or PAH severity grade., Conclusions: Patients with IPAH are characterized by an altered profile of lipid and glucose metabolism. Lowered levels of LDL-C and HDL-C and increased TG/HDL-C ratio correlate with disease severity and together with elevated plasma glucose level predict poor survival in IPAH., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2018 Termedia & Banach.)

- Abstract
Background: Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease and the population of ToF repair survivors is growing rapidly. Adults with repaired ToF develop late complications. The aim of this study was to describe and analyze long-term follow-up of patients with repaired ToF., Methods: This is a retrospective cohort study. Consecutive 83 patients with repaired ToF who did not undergo pulmonary valve replacement were included. Mean age of all patients was 30.5 ± 10.7. There were 49 (59%) male. Patients were divided into two groups according to the time since the repair (< 25 years and ≥ 25 years). The electrocardiographic (ECG), cardiopulmonary exercise testing (CPET), echocardiographic and cardiac magnetic resonance (CMR) data were reviewed retrospectively., Results: In CPET values were not significantly different in the two groups. In CMR volumes of left and right ventricles were not significantly different in the two groups. There were no differences between the groups in ventricular ejection fraction, mass of ventricles, or pulmonary regurgitation fraction. Among all the patients, ejection fraction and left and right ventricle mass, indexed pulmonary regurgitation volume measured by CMR did not correlate with the time since repair. In ECG among all the patients, ejection fraction of the RV, measured in CMR, negatively correlated with QRS duration (r = - 0.43; p < 0.001). There was a positive correlation between QRS duration and end diastolic volume of the RV (r = 0.30; p < 0.02), indexed end diastolic volume of the RV (r = 0.29; p = 0.04), RV mass (r = 0.36; p < 0.001) and left ventricle mass (r = 0.26; p = 0.04)., Conclusion: Long-term survival and clinical condition after surgical correction of ToF in infancy is generally good and the late functional status in ToF - operated patients could be excellent up to 25 years after the repair. QRS duration could be an utility and easy factor to assessment of right ventricular function., Trial Registration: The study protocol was approved by the local Ethics Committee. Each participant provided informed consent to participate in the study (license number 122.6120.88.2016 from 28.04.2016).

- Abstract
The aim of this study is to assess the relationship between autoimmunity and endothelial activation/damage (ICAM-1 and vWF serum levels) and the degree of prothrombotic activity (thrombin-antithrombin complexes-TAT serum levels) in SLE. In 60 clinically stable SLE patients, levels of the following parameters were estimated in their serum: lupus anticoagulant (LA), anticardiolipin antibodies in both IgG and IgM classes (aCL-IgG and aCL-IgM, respectively), antiβ2GPI antibodies in both IgG and IgM classes (antiβ2GPI-IgG and antiβ2GPI-IgM, respectively), ICAM, von Willebrand factor (vWF), TAT, CRP, C3c, C4, and IL-6. ICAM-1 values exceeded the upper reference limit in 9 (15%) patients. vWF levels were increased in 21 (35%) patients. In all patients with elevated ICAM-1 values, vWF were also increased. TAT concentrations were elevated in 12 (20%) people. ICAM-1 were significantly higher in patients with elevated aCL-IgM (> 30 MPL vs ≤ 30 MPL; p < 0.05). Similarly, ICAM-1 were significantly higher in patients with elevated antiβ2-GPI-IgM (> 20 SMU vs ≤ 20 SMU; p < 0.05). There was no significant difference in ICAM-1 levels in relation to LA-positivity. vWF were not significantly different in relation to antiphospholipid antibodies nor the inflammation marker levels. TAT were significantly higher in patients with elevated aCL-IgM (> 30 MPL vs ≤ 30 MPL; p < 0.05). In one third of young patients with stable SLE, signs of endothelial activation/damage were found, as shown by elevated plasma ICAM-1 or vWF. Increased prothrombotic tendency manifested by elevated TAT was found in one fifth of the patients. Elevated anticardiolipin (IgM) and anti-β2-glycoprotein I (IgM) antibodies influence endothelial dysfunction and enhance prothrombotic state.

- Abstract
Background: Opioidergic conditioning is well documented to trigger cardioprotection against ischemia/ reperfusion (I/R) injury. Previous studies on animal models have suggested that nitric oxide (NO) mediates the beneficial effect of opioids, but the role of NO in humans seems to be controversial., Objectives: The aim of the study was to assess the influence of NO modulators on opioid-induced cardioprotection in the human myocardium., Material and Methods: Trabeculae of the human right atria were electrically driven in an organ bath and subjected to simulated I/R injury. The non-selective inhibitor of nitric oxide synthase (NOS) - N-methyl-l-arginine (LNMMA), the donor of NO - S-Nitroso-N-acetylpenicillamine (SNAP) or morphine (in the amount of 10-4 M) were used at the time of re-oxygenation. The additional trabecula was subjected to the hypoxia protocol only (control). The contractility of the myocardium was assessed as the maximal force of a contraction (Amax), the rate of rise of the force of a contraction (Slope L) and the cardiac muscle relaxation - as the rate of decay of the force of a contraction (Slope T)., Results: The application of 100 μM LNMMA resulted in the decrease of Amax, Slope L and Slope T during the re-oxygenation period as compared to control. The application of 10-4 M morphine and/or 100 μM SNAP resulted in a partial reversal of the detrimental influence of LNMMA., Conclusions: At the re-oxygenation period, the blockade of NO synthesis has a deleterious effect on the systolic and diastolic function of the human myocardium as well as attenuates the beneficial effect of morphine conditioning.

- Abstract
BACKGROUND Neurogenic mechanism is believed to contribute to left ventricular (LV) systolic dysfunction in acute coronary syndromes (ACS); its extreme form is known as takotsubo cardiomyopathy. However, the magnitude of neurogenic contribution to LV dysfunction in all-comer first-time ACS remains unknown. MATERIAL AND METHODS In 120 consecutive patients with first-time ACS (age 66.3±12.3years, 40 women) coronary angiograms were individually matched to the echocardiographic left ventricular (LV) segments (17-segment model). Baseline contractility impairment was classified as ischemic (I): confined to the stenotic artery(ies) supply area(s), neurogenic (N): in absence of attributable coronary stenosis, or partially ischemic/partially neurogenic (I&N). Echocardiography was repeated at 6 months to determine LV systolic function recovery. RESULTS Neurogenic component (NC) contribution to myocardial contractility impairment was present in 24.2% of ACS patients, with pure N in 6.7% and I&N in 17.5%. Diabetes/pre-diabetes was present in 38.5% vs. 33.5% vs. 0% (I vs. I&N vs. N; p=0.02). Major stressor preceding symptom onset was reported in 3.3% in I, 9.5% in I&N, and 25.0% in N (p=0.03). The number of LV segments with contractility impairment was 2±4 in I, 17±11 in I&N, and 3±16 in N (p<0.05). NC presence was independently associated with better recovery of global LV systolic function (OR 2.99, 95% CI: 1.16-7.76; p=0.024). CONCLUSIONS Novel findings from this study are: (1) NC may contribute to myocardial contractility impairment in 1 in every 4 first-time ACS patients, (2) NC contribution to contractility impairment in ACS is blunted in diabetes or pre-diabetes, and (3) LV systolic function recovery is better in patients with NC.

- Abstract
BACKGROUND The Fontan procedure, performed for univentricular heart, may also include the technique of percutaneous fenestration to create a small atrial septal defect (ASD) and a right-to-left shunt. The aim of this study was to evaluate the long-term effects of fenestration in adult patients who had a Fontan procedure for univentricular heart. MATERIAL AND METHODS Fontan surgery was performed in 39 patients, including 19 (49%) patients with fenestration (Group I), and 20 (51%) patients without the fenestration procedure (Group II). Laboratory tests in both groups included echocardiography, plethysmography, cardiopulmonary exercise testing, and 24-hour Holter monitoring. RESULTS Compared with patients in Group I, patients in Group II had a significantly increased level of N-terminal pro-brain natriuretic peptide (NT-proBNP) (p=0.04), alkaline phosphatase (ALP) (p=0.01) and a significant increase in frequency of atrial fibrillation (p=0.04). Patients in Group I had a significantly increased systemic ventricular ejection fraction (SVEF) (p=0.05) and increased heart rate (HR) (p=0.006), heart rate reserve (HRR) (p=0.02), ventilatory equivalent (VE) (p=0.01), and VO2 peak (p=0.05) on cardiopulmonary exercise testing (CPET). Renal, hematologic, and ventilatory parameters, and incidence of thromboembolism showed no significant differences between the groups. CONCLUSIONS Long-term follow-up of patients who underwent Fontan procedures with percutaneous fenestration had improved single ventricular function, lower NT-proBNP levels, improved exercise capacity, and reduced ALP levels. These findings indicate that percutaneous fenestration closure should be considered for adult patients who have undergone Fontan procedure for univentricular heart.

- Abstract
Background: Despite the low early mortality of Fontan procedures, Fontan patients are prone to vari-ous cardiac and extra-cardiac complications in the long term. This may influence patient perception of their health and outcome. The aim of the study was to assess the relationship of multi-organ compli-cations and physical efficiency with self-reported health-related quality of life (QOL) in adult Fontan patients., Methods: Quality of life was assessed with the Short Form-36 questionnaire. Laboratory tests were done together with echocardiography, plethysmography, and cardiopulmonary exercise test., Results: The QOL was poorer in patients than in control subjects. The physical characteristics of patients correlated with dynamic ventilatory parameters, heart rate at the peak of exercise, alanine aminotransferase and albumin level., Conclusions: Liver impairment and chronotropic incompetence during exercise are associated with poor QOL in patients after Fontan procedure. In these patient, hepatic, pulmonary and cardiac functions should be carefully monitored. (Cardiol J 2018; 25, 1: 72-80).

- Abstract
Left ventricular reverse remodeling (LVRR) is reported in dilated cardiomyopathy (DCM) patients (pts). However, numerous definitions of LVRR exist. Measurements of serum markers of fibrosis provide insight into myocardial fibrosis. The relationship between LVRR and fibrosis is poorly understood. From July 2014 until October 2015, we included 63 consecutive DCM pts (48 ± 12.1 years, EF 24.4 ± 7.4%) with completed baseline and 3-month follow-up echocardiograms. LVRR was assessed on the basis of four differing definitions. Procollagens type I and III carboxy- and amino-terminal peptides (PICP, PINP, PIIICP, and PIIINP), collagen 1, ostepontin, tumor growth factor beta-1, connective tissue growth factor, and matrix metalloproteinases (MMP-2, MMP-9), and their tissue inhibitor (TIMP-1) were measured in serum. In addition, all pts underwent right ventricular endomyocardial biopsy. Depending on the definition chosen, LVRR could be diagnosed in between 14.3 and 50.8% pts. Regardless of the LVRR definition used, the frequency of LVRR was similar in fibrosis negative and positive DCM. Minor differences of markers of fibrosis were detected between pts with and without LVRR. For every LVRR definition, adjusted and unadjusted models were constructed to evaluate the predictive value of serum fibrosis parameters. Only an increase of TIMP-1 by 1 ng/ml was found to independently increase the probability of LVRR by 0.016%. The choice of a particular definition of LVRR determines the final diagnosis, and this has a profound impact on subsequent management. LVRR is unrelated to biopsy-detected ECM fibrosis. Serum markers of fibrosis are only weakly related to LVRR, and are not of use in the prediction of LVRR.

- Abstract
Ischemic heart disease have been remarked as a leading cause of morbidity and mortality in adults. Early restoration of cardiac perfusion is necessary to restore perfusion of ischemic heart muscle. Effective revascularization reduce mortality by limiting myocardial necrosis at the acute phase of the cardiac infarction. However, reperfusion may induce a cascade of pathophysiological reactions causing the increase of the infarct area of the myocardium This phenomenon known as ischemia-reperfusion injury is responsible for up to 50% of the final infarct size. Sequences of brief episodes of nonlethal ischemia and reperfusion applied before (preconditioning - IPC) or after (postconditioning - POC) the coronary occlusion are well documented to reduce the ischemiareperfusion injury. These phenomena improve cardiac function by mobilizing the molecular and cellular mechanisms limiting reperfusion injury. The mechanisms underlying IPC or POC are still not clarified, but strong experimental evidence suggests that opioids may be the part of the endogenous cardioprotective response to I/R injury. Stimulation of opioid receptors activates related to POC mechanisms affecting protection to the ischemic myocardium, while the use of non-selective opioid receptor antagonist - naloxone reduces this effect. There is no consensus that the subtype of opioid receptor is responsible for the protection of the human heart muscle. Morphine may reduce cardiac preload by peripheral vasodilatation. Numerous studies show a direct cardioprotective effect of the opioid pathway in ischemic conditions. Opioids act via membrane receptors: μ, δ, κ. The predominant subtype in the human cardiac cells are μ- and δ - opioid receptors. It has been hypothetized that opioid receptor activation exerts cardioprotection in human heart muscle pathway what may give insight into the explanation of the protective mechanisms in the acute myocardial infarction.

- Abstract
Background: Despite progress in the invasive treatment of ischemic heart disease, the ability to limit ischemia-reperfusion (I/R) injury remains largely unrealized. Ischemic pre-conditioning (IPC) and post-conditioning (POC) induce the protective mechanisms of resistance against I/R injury. Stimulation of opioid receptors mimic the protective effect of IPC or POC in an animal models. We tested the hypothesis, that IPC and POC provide cardioprotection in opioid-dependent mechanism in human myocardium., Methods: Human atrial trabeculae were subjected to I/R injury. To achieve IPC, single hypoxia period preceded the applied lethal hypoxia, to achieve POC triple hypoxia periods followed lethal hypoxia. Naloxone was used at the onset of lethal hypoxia in IPC protocol, and at the time of re-oxygenation in POC protocol. Contractive function of the myocardium was assessed as maximal force of contraction (Amax), rate of rise of force of contraction (+dV/dT) and diastolic parameter - rate of decay of force of contraction (-dV/dT)., Results: Co-application of naloxone with IPC or POC resulted in decrease of Amax, +dV/dT and -dV/dT during re-oxygenation period as compared to IPC or POC only., Conclusions: Naloxone abrogates beneficial effect of IPC and POC. IPC and POC in humans provide cardioprotection in opioid receptor system dependent mechanism.

- Abstract
Background: Ischemic preconditioning and postconditioning are the novel strategies of attaining cardioprotection against ischemia/reperfusion (I/R) injury. Previous studies suggested the role of opioid pathway, however the class of opioid receptors responsible for this effect in humans remains unknown. The aim of the study was to assess the influence of opioids on simulated I/R injury outcomes in the hu-man myocardium., Methods: Trabeculae of the human right atrium were electrically driven in organ bath and subjected to simulated I/R injury. Morphine (10-4M, 10-5M, 10-6M) or d-opioid receptor agonist DADLE (10-8M, 10-7M, 10-6M) was used at the time of re-oxygenation. Additional trabecula was subjected to hypoxia protocol only (Control). Contractive force of the myocardium was assessed as the maximal force of a contraction (Amax), the rate of rise of the force of a contraction (Slope L) and relaxation as the rate of decay of the force of a contraction (Slope T)., Results: Application of morphine 10-4M resulted in increase of Amax, Slope L and Slope T during re-oxygenation period as compared to Control (77.99 ± 1.5% vs. 68.8 ± 2.2%, p < 0.05; 45.72 ± 2.9% vs. 34.12 ± 5.1%, p < 0.05; 40.95 ± 2.5% vs. 32.37 ± 4.3%, p < 0.05). Parameters were not significantly different in the lower morphine concentrations. Application of DADLE 10-6M resulted in decrease of Amax and Slope L as compared to Control (68.13 ± 5.5% vs. 76.62 ± 6.6%, p < 0.05; 28.29 ± 2.2 vs. 34.80 ± 3.9%, p < 0.05)., Conclusions: At re-oxygenation, morphine improves systolic and diastolic function of the human myo-cardium in the dose-dependent manner. Delta-opioid receptor stimulation attenuates systolic function of human heart muscle which remains in contrast to previous reports with animal models of I/R injury. (Cardiol J 2017; 24, 4: 419-425).

- Abstract
Background: Thrombotic events in antiphospholipid syndrome (APS) involve venous and arterial circulation with the possible involvement of coronary or pulmonary microcirculation., Objectives: To evaluate the influence of antiphospholipid antibodies (aPL) and on myocardial ischaemia assessed by single-photon emission computerized tomography (SPECT), coronary atherosclerosis assessed by multidetector computerized tomography (MDCT) and pulmonary pressure assessed by transthoracic echocardiography (TTE) in patients with primary antiphospholipid syndrome (PAPS)., Material and Methods: TTE, SPECT (Tc 99m sestamibi) and MDCT-based coronary calcium scoring were performed in 26 consecutive PAPS patients (20 females, 6 males, aged 20-61, mean 39.7) without any signs of other autoimmunological disease and without clinical symptoms of heart disease., Results: Out of 26 patients, TEE showed normal left and right ventricle function in 25 (96.2%) and elevated (≥ 30 mm Hg) right ventricle systolic pressure in 7 (26.9%) patients. SPECT revealed myocardial perfusion defects in 15 (57.7%) patients: exercise-induced in 6 (23.1%) and persistent in 11 (42.3%). MDCT revealed coronary calcifications in 4 (15.4%) patients. The number of plaques ranged from 1 to 11 (median 2), volume 3-201.7 mm³ (median 7), calcium scores 1.3-202.6 (median 5.7). In the group with perfusion defects or coronary calcifications (n = 15), all the patients showed elevated aCL IgG., Conclusions: In most of the relatively young APS patients, without any symptoms of ischemic heart disease, SPECT showed myocardial perfusion defects, and coronary calcifications in 1/6 of them. Right ventricle systolic pressure was elevated in 1/4 of APS patients. These pathologies, well known as cardiovascular risk markers, were associated with elevated levels of the IgG class of both anti-cardiolipin and antiB2 GPI antibodies. Thus, in a high percentage of APS patients, clinically silent myocardial ischaemia, pulmonary pressure elevation and coronary atherosclerosis are present and related to the presence of antiphospholipid antibodies.

- Abstract
Background: The study aimed to assess the level of plasma Endothelin-1 (ET-1) in patients before and after transcatheter closure of atrial septal defect (ASD) and to evaluate the usefulness of measuring ET-1 levels for the diagnosis and selection of candidates for ASD closure., Methods: 80 patients (55 F, 25 M), mean age 42,2 ± 11,5 years were enrolled for an attempt at ASD closure. A group of 19 healthy volunteers, (12 F, 7 M) mean age 39.2 ± 9.15 served as controls. All ASD patients underwent: clinical and echocardiographic study and cardiopulmonary exercise test. ET-1 levels were measured before and after closure. Whole blood was collected from femoral artery and vein and from pulmonary artery during cardiac catheterization., Results: ET-1 levels at peripheral artery and vein in ASD patients were significantly higher than in the volunteers (p < 0.0001). The ASD subjects with highest ET-1 level presented the larger area of right ventricle and right atrium and higher pulmonary artery systolic pressure(p < 0.05). The ASD subjects with lower ET-1 level demonstrated longer time of exercise and higher peak oxygen consumption (p < 0.05). There was a decrease of ET-1 at peripheral artery (5.128 ± 8.8 vs. 2.22 ± 6.2; p < 0.001) and at peripheral vein (4.401 ± 3.33 vs. 2.05 ± 1.35; p < 0.001) within 48 hours after ASD closure, as compared to the baseline data. After 6 and 12 months farther drop in ET-1 level was observed., Conclusions: 1. The level of ET-1 in ASD patients is elevated in compare to healthy subject.2. The significant reduction of ET-1 level is observed after percutaneous closure of ASD.3. Elevated level of ET-1 in patients with ASD is associated with right heart enlargement.4. Measurements of ET-1 may be a supplemental diagnostic tool and may be helpful in establishing indications for defect closure.

- Abstract
Background: Gradual impairment of exercise tolerance is the commonest sign of heart failure (HF). Little is known as to which cardiac contributors of poor exercise capacity carry an independent prognostic information in HF., Aim: We investigated the prognostic role of exercise echocardiography (ex-echo) in HF patients., Methods: We studied 85 consecutive, symptomatic HF patients (66 males, mean age 62.5 ± 11.8 [range 21-83] years, mean left ventricular ejection fraction [LVEF] 27.2 ± 9.5%). The end-point was all-cause mortality. During the follow-up period (mean 43 ± 21 months) 21 patients died. Resting echocardiography and ex-echo, with the simultaneous measurement of peak oxygen uptake (VO(2peak)), was performed in each patient using a semi-supine ergometer (20 W, 2-min increments). Apart from conventional assessment of systolic and diastolic function (EF, E/A, DT, IVRT) or right ventricular systolic pressure (RVSP), tissue Doppler imaging was used for the assessment of LV and RV peak velocity (IVV) as well as acceleration during isovolumic contraction (IVA), peak velocity during ejection phase (S'), peak early diastolic velocity (E'), peak late diastolic velocity (A'), and ratio of early diastolic mitral/tricuspid velocity to peak early diastolic velocity (E/E')., Results: Patients who died were significantly older, had lower exercise capacity, more advanced HF, greater impairment of baseline systolic function, higher baseline pulmonary artery systolic pressure, and most importantly a lack of improvement in EF, diastolic function, and further increase of RVSP during exercise. Out of all echocardiographic parameters, only peak stress EF (x(2) 6.1; p = 0.01), baseline and peak exercise RVSP (x(2) 12.5 and c(2) 18.7; p 〈 0.001; respectively), and mitral E/E' ratio (x(2) 8.9; p 〈 0.01) were univariate predictors of prognosis and remained independently prognostic when adjusted for age and sex but were eliminated from the model by NT-proBNP., Conclusions: During exercise, more severe systolic and diastolic dysfunction with the elevation of pulmonary arterial pressure is more prevalent in HF patients who have a poorer outcome. The estimation of common parameters such as EF, RVSP and E/E' using ex-echo, provides prognostic information in HF.

- Abstract
Background: Diastolic heart dysfunction, responsible for dyspnoea in heart failure patients, is an important prognostic factor. Patients with systemic sclerosis (SSc) serve as a model of diastolic heart failure with preserved ejection fraction., Aim: To quantify diastolic left ventricular (LV) dysfunction and elevation of pulmonary capillary wedge pressures (PCWP) in SSc patients and to assess the effects of these parameters on exercise tolerance., Methods: In 46 SSc patients (43 females, three males, aged 24-73 years) and 30 healthy females, echocardiography with tissue Doppler (TDE) and cardiopulmonary exercise tests (CPX) were performed. During TDE, the systolic (S) and early diastolic (E) velocities of mitral annulus were recorded. The PCWP was calculated on the basis of mitral inflow E velocity and E velocity of mitral annulus. The CPX was performed using a modified Bruce protocol., Results: Left ventricular ejection fraction was normal in the SSc group. Mitral inflow E/A ratio was pseudonormal in five SSc patients, and significantly decreased in the remainder as compared to controls (0.87 ± 0.2 vs 1.38 ± 0.5, p < 0.0002). The TDE examination confirmed normal systolic LV function, but severe LV diastolic dysfunction (E 8.66 ± 2.5 cm/s vs 12.39 ± 3.5 cm/s in controls, p < 0.000002). The PCWP was higher in the SSc group (11.8 ± 3.3 mm Hg vs 7.7 ± 1.7 mm Hg in controls, p < 0.0001). The PCWP > 10 mm Hg significantly decreased exercise duration, maximal oxygen uptake and carbon dioxide output and identified patients with oxygen uptake < 20 mL/kg/min with 100% sensitivity and 78% specificity. The ventilatory equivalent of carbon dioxide was increased in the SSc group (VE/VCO2 38.7 ± 7.5 vs 30.55 ± 4.2 in controls, p < 0.002)., Conclusions: Pure LV diastolic dysfunction, typical of SSc, leads to the elevation of PCWP. Values of PCWP > 10 mm Hg are associated with severe exercise intolerance demonstrated by shorter duration of exercise with decreased oxygen uptake and carbon dioxide output during exercise.

- Abstract
Background: Severe cardiovascular complications are among the most important causes of mortality in systemic lupus erythematosus (SLE) patients., Aim: To assess the usefulness of echocardiography, ECG, and coronary artery calcium scoring (CACS) in the detection of myocardial ischaemia in SLE patients compared to single photon emission computerised tomography (SPECT) and to assess their five-year follow-up., Methods: In 50 consecutive SLE patients (mean age 39.2 ± 12.9 years, 90% female), clinical assessment, resting and exercise ECG and echocardiography, multidetector computed tomography - based CACS and SPECT studies (Tc-99m sestamibi) were performed. Patients were then followed for five years., Results: SPECT revealed perfusion defects in 25 (50%) patients; persistent defects in 18 (36%) and exercise-induced defects in seven (14%) subjects. No typical ischaemic heart disease clinical symptoms, signs of ischaemia in resting ECG, or left ventricular contractility impairment in echocardiography were observed. Signs of ischaemia in exercise ECG were found in 17 (34%) patients. The CACS ranged from 1 to 843.2 (median 23.15), and coronary calcifications were observed in 12 (24%) patients. Compared to the SPECT study, exercise ECG had 68% sensitivity and 100% specificity in detecting myocardial ischaemia, while CACS had only 28% sensitivity and 58% specificity. During follow-up, one patient who showed myocardial perfusion defects and the highest calcium score (843.2) at baseline, developed CCS II class symptoms of myocardial ischaemia. Coronary angiography was not performed because of severe anaemia; the patient died three months later. In two other patients with perfusion defects and calcium deposits at baseline, CCS I class symptoms were observed; coronary angiography showed only thin calcified coronary plaques that were haemodynamically insignificant., Conclusions: In about half of relatively young, mostly female, SLE patients, SPECT shows myocardial perfusion defects, with coronary calcifications present in one quarter of them. While ECG and echocardiography may not reveal any pathology, ECG exercise test can identify these patients with high specificity. In patients with a negative SPECT, the short-term prognosis is good, while in patients with perfusion defects and coronary calcifications, the clinical symptoms of myocardial ischaemia could occurr. However, at a low calcium score ( < 150), the short-term risk of significant atherosclerosis progression is low.

- Abstract
Introduction: Patients with right ventricle (RV) pressure overload often have impaired left ventricular (LV) diastolic function. Objectives. The aim of study was to evaluate LV function in patients with chronic obstructive pulmonary disease (COPD). Patients and methods. Thirty-five patients (mean age: 62.1 +/- 7.7 y) with COPD without additional cardiac diseases and 25 age--and sex-matched healthy subjects were enrolled into the study. All patients underwent resting ECG tracing, blood pressure, spirometry, standard and tissue Doppler echocardiography., Results: The mean value of forced expiratory volume in one second (FEV1) in the COPD group was 40 +/- 8.9% of the predicted value. We found no significant differences in LV end-diastolic and systolic diameter and interventricular septum as well between COPD patients and controls. RV end-diastolic diameter and RV wall thickness were significantly larger and right ventricle systolic pressure--RVSP (38 +/- 11.2 vs. 20 +/- 2.5 mm Hg) significantly higher in the COPD group. Both peak early to peak atrial filling velocities ratio--E/A and peak annular velocity during early diastole to peak annular velocity during atrial contraction--Em/Am were significantly lower in COPD compared to controls. Moreover, there was a strong inverse correlation between Em/Am and RVSP (r = -0.75; p < 0.001) and between E/A (r = -0.6; p < 0.001) as well. We found no significant differences in parameters assessing the LV systolic function between both groups., Conclusions: In COPD patients LV diastolic function is significantly impaired and its magnitude is related with increase in pulmonary artery pressure, while systolic LV function is well preserved.

- Abstract
A case of a 70 year old female with hypertrophic obstructive cardiomyopathy who underwent alcohol ablation of the interventricular septum, is presented. Following the procedure, the pressure gradient decreased from 120 mmHg to 80 mmHg. However, 30 minutes after ablation the patients developed hypotension and pulmonary oedema. Echocardiography revealed a significant systolic anterior movement of the anterior leaflet of the mitral valve and elevated pressure gradient up to 200 mmHg. The patient underwent urgent surgery (myectomy), followed by the mitral valve replacement with a favourable outcome.

- Abstract
Background: Percutaneous transluminal septal myocardial ablation (PTSMA) is becoming an alternative to surgical myectomy in the treatment of severe, drug refractory, hypertrophic obstructive cardiomyopathy (HOCM). The aim of our study was to analyze early results, complications and long-term follow-up in patients after PTSMA., Methods: Out of eighteen patients [11 M] initially accepted for PTSMA, the procedure was performed in 12 patients [6 M] age from 22 to 70 y. All the patients underwent clinical evaluation, echocardiography and cardiopulmonary exercise testing (CPX) before the procedure, and after a median of 38 months of observation. In echo-cardiography left ventricle outflow tract gradient (LVOTG) and intraventricular septum diastolic diameter were assessed. The following parameters of CPX were analyzed: exercise duration, anaerobic threshold, peak oxygen consumption, peak exercise heart rate and carbon dioxide ventilating equivalent., Results: The procedure was successful in 11 patient. There were 2 acute complications: 3rd degree AV block requiring peacemaker implantation and LVOTG increase with SAM exacerbation requiring urgent cardiosurgical intervention. During long-term follow-up 1 cerebral stroke and 1 death occurred. PTSMA resulted in significant reduction of left ventricle outflow tract gradient (89 +/- 44 vs. 17 +/- 17 mmHg) and intraventricular septum diastolic diameter (24 +/- 4 vs 18 +/- 5 mm) (p < or = 0.01 for both). We also observed improvement of CPX parameters: exercise duration (487 +/- 268 vs. 730 +/- 292 sec), anaerobic threshold (34.3 +/- 8.9 vs. 53.2 +/- 13.4% VO2max predicted), peak oxygen consumption (18.5 +/- 6 vs. 26.8 +/- 10.1 ml/kg/min), peak exercise heart rate (70.3 +/- 8.3 vs. 83.6 +/- 11.7%) and carbon dioxide ventilating equivalent (31 +/- 6.1 vs. 28 +/- 4.8); (p < or = 0.01 for all)., Conclusions: PTSMA is an effective method of treatment in patients with severe, drug refractory HOCM. PTSMA is safe and is associated with a low percentage of severe complications.

- Abstract
Background: Femoral artery pseudoaneurysm (FAP) complicates from 1% to 9% of all coronary angiography procedures and contributes to extended hospitalisation as well as patient discomfort., Aim: To compare three main methods of FAP closure which are used nowadays., Methods: Seventy-five subjects (38 females, 37 males, mean age 60.8+/-10.4 years) with post-catheterisation FAP were studied. The results of three methods of FAP closure--surgical, local compression and thrombin injection--were compared., Results: Between September 2000 and July 2001, fourteen patients developed FAP; in 9 (64%) patients FAP was closed with repeated prolonged compression whereas the remaining 5 (36%) patients required surgical closure of compression-resistant FAP. We observed that FAPs with longer neck (>10 mm) and primary signs of partial spontaneous coagulation were more prone to self-closure as compared to FAPs with short neck and no signs of perimural coagulation (p=0.01). Since July 2001, we introduced ultrasound-guided thrombin injection into FAP sack. The protocol included attempt of closing FAP with probe compression and compression dressing put overnight, and, if unsuccessful, followed by a quick injection of 2 ml of thrombin solution (400-3200 U), guided by ultrasound. During this period, we identified 61 patients with FAP. Out of this group, 5 (8.2%) subjects were referred for surgery without any attempt of thrombin-injection, in 16 (26.2%) patients FAP was closed with probe compression and dressing put overnight, and in the remaining 40 (65.6%) subjects ultrasound-guided thrombin-injection was performed. Thrombin injection into FAP sack caused closure of its cavity and neck in all patients, however, five patients required additional thrombin injection during the same session, and 2 (5.0%) patients--during the next procedure. No peri-procedural complications were observed. The duration of hospital stay shortened from a mean of 26.6+/-14.5 days in surgically treated patients to 7.9+/-6.7 in those in whom FAPs were closed with compression, and to 4.6+/-2.6 days in those treated with thrombin (p<0.001). During a mean follow-up of 11+/-8.1 months, we re-examined 32 (80.0%) patients in whom FAP was closed with thrombin injection. No long-term thrombotic or embolic complications were observed. However, in 2 (6.3%) patients FAP cavity did not undergo complete resorption after 6 and 12 months of follow-up., Conclusions: Thrombin-induced closure of femoral pseudoaneurysm is a quick, safe and effective method, shortening hospitalisation time. In our Department this procedure replaced the prolonged and painful compression method.

- Abstract
Introduction: Tissue Doppler imaging (TDI) facilitates the quantitative assessment of the regional systolic and diastolic left ventricle function. Heart scintigraphy (SPECT) facilitates the assessment of regional perfusion of the myocardium. The aim of the study was the evaluation of the correlation between the regional myocardial perfusion defects observed in the SPECT study and the regional systolic and diastolic left ventricle function observed in TDI examination in the ischaemic heart disease patients., Material and Methods: In 40 patients (33 men and 7 women) aged 43-74 years (mean age 56 years) diagnosed of ischaemic heart disease on the basis of coronary angiography, rest TDI examination was performed. Maximal systolic and maximal early-diastolic myocardial velocities were assessed in 13 myocardial segments of the left ventricle, supplied by respective coronary arteries (left anterior descending artery--LAD, circumflex artery--Cx, right coronary artery--RCA). During rest and exercise perfusion scintigraphy of the heart (Tc99 MIBI SPECT) myocardial perfusion was evaluated in the segments analysed previously during TDI study. On the basis of the SPECT examination results the patients were divided into three groups: group I) patients with fixed perfusion defects, group II) patients with exercise-induced perfusion defects and normal rest perfusion, group III) patients with normal perfusion during rest and exercise., Results: Systolic and diastolic myocardial velocity in LAD and Cx supplied segments were significantly higher in group II and group III as compared with group I. Systolic and diastolic velocities of myocardium supplied by LAD were significantly lower in group II as compared with group III. In Cx supplied region the diastolic myocardial velocity was significantly lower in group II as compared with group Ill., Conclusions: In the left ventricle myocardial regions with fixed perfusion defects, statistically significant decrease of systolic and diastolic myocardial velocities was observed. Moreover, the decrease of diastolic myocardial velocity in the rest TDI examination was found in patients with normal rest perfusion and exercise-induced perfusion defects.
