RESUMEN
BACKGROUND: Recent studies revealed that alterations in glucose and lipid metabolism in idiopathic pulmonary arterial hypertension (IPAH) are associated with disease severity and poor survival. However, data regarding the impact of diabetes mellitus (DM) on the prognosis of patients with IPAH remain scarce. The aim of our study was to determine that impact using data from a national multicentre prospective pulmonary hypertension registry. METHODS: We analysed data of adult patients with IPAH from the Database of Pulmonary Hypertension in the Polish population (BNPPL) between March 1, 2018 and August 31, 2020. Upon admission, clinical, echocardiographic, and haemodynamic data were collected at 21 Polish IPAH reference centres. The all-cause mortality was assessed during a 30-month follow-up period. To adjust for differences in age, body mass index (BMI), and comorbidities between patients with and without DM, a 2-group propensity score matching was performed using a 1:1 pairing algorithm. RESULTS: A total of 532 patients with IPAH were included in the study and 25.6% were diagnosed with DM. Further matched analysis was performed in 136 patients with DM and 136 without DM. DM was associated with older age, higher BMI, more advanced exertional dyspnea, increased levels of N-terminal pro-brain natriuretic peptide, larger right atrial area, increased mean right atrial pressure, mean pulmonary artery pressure, pulmonary vascular resistance, and all-cause mortality compared with no DM. CONCLUSIONS: Patients with IPAH and DM present with more advanced pulmonary vascular disease and worse survival than counterparts without DM independently of age, BMI, and cardiovascular comorbidities.

The possibility of using a smartwatch as a rehabilitation tool to monitor patients' heart rates during exercise has gained the attention of many researchers. This study aimed to evaluate the accuracy and precision of the HR measurement performed by two wrist monitors: the Fitbit Charge 4 and the Xiaomi Mi Band 5. Thirty-one healthy volunteers were asked to perform a stress test on a treadmill. Their heart rates were recorded simultaneously by the wristbands and an electrocardiogram (ECG) at 1 min intervals. The mean absolute error percentage (MAPE), Lin's concordance correlation coefficient (LCCC), and Bland-Altman analysis were calculated to compare the precision and accuracy of heart rate measurements. The estimated validation criteria were MAPE < 10% and LCCC < 0.8. The overall MAPE and LCCC of the Fitbit were 10.19% (±11.79%) and 0.753 (95% CI: 0.717-0.785), respectively. The MAPE and LCCC of the Xiaomi were 6.89% (±9.75) and 0.903 (0.886-0.917), respectively. The precision and accuracy of both devices decreased with the increased exercise intensity. The accuracy of wearable wrist-worn heart rate monitors varies and depends on the intensity of training. Therefore, the decision to use such a device as a heart rate monitor during in-home rehabilitation should be made with caution.

Introduction: Regenerative capacity of the heart is limited, and the post-infarct left ventricle (LV) dysfunction is associated with poor prognosis. Administration of stem/progenitor cells (SPCs) is a promising approach for cardiac regeneration. Objectives: In the study, we assessed LV function and post-infarcted remodeling in patients with ST-elevated myocardial infarct (STEMI) who received autologous lineage-negative (LIN-) SPCs. Patients and methods: Patients with STEMI and one-vessel coronary artery disease treated with percutaneous revascularisation were divided into study group (LIN- group, 15 patients) that received standard therapy and autologous BM-derived LIN- SPCs and control group (standard therapy group, 19 patients). The cells were administered intracoronary 24 hours after STEMI. The follow-up was 12 months with subsequent non-invasive tests and laboratory parameter evaluation on days 1st, 3rd, and 7th as well as at 1st, 3rd, 6th and 12th month after STEMI. Results: All procedures related to SPCs administration were well tolerated by the patients. In 12-month follow-up, there were no major adverse cardiac events connected with LIN- SPCs administration. During 12-month follow-up, 9 patients from LIN- group (Responders) achieved an improvement in LV ejection fraction (>10% after 12 months) with no signs of unfavorable LV remodeling. Laboratory parameters analysis showed that Troponin T levels were significantly lower until day 7th in the Responders group, while brain natriuretic peptide (BNP) level remained significantly lower from day 3rd to 12th month respectively. Conclusions: Intracoronary infusion of autologous BM-derived LIN- stem/progenitor cells is feasible and safe for patient. Improvement in LV function and prevention of unfavorable remodeling in the 60% of study group seems relatively promising. Stem cell-based therapy for cardiac regeneration still needs more accurate and extensive investigations to estimate and improve their efficacy.

BACKGROUND AND OBJECTIVES: The goal was to evaluate the association of dynamic retinal vessel analysis (DVA) with echocardiographic parameters assessing systolic and diastolic function of the left ventricle in hypertension (HT) patients with preserved left ventricle ejection fraction. MATERIALS AND METHODS: This observational retrospective study recruited 36 patients with HT and 28 healthy controls. Retinal vessel diameter and reactions to flicker light were examined. Each patient was examined with echocardiography to assess left ventricular systolic and diastolic function. RESULTS: Multivariate analysis revealed that hypertension was an independent factor associated with lower flicker-induced arterial vasodilatation (ß = -0.31, p = 0.029). In the HT group, there was a significant positive association between left ventricular ejection fraction and flicker-induced arterial vasodilation (Rs = +0.31, p = 0.007). Additionally, end-diastolic left ventricular diameter negatively correlated with both arterial (Rs = -0.26, p = 0.02) and venous (Rs = -0.27, p = 0.02) flicker responses. Additionally, the echocardiographic characteristics of the left atrium (LA) remodeling in the course of HT, including the area of the LA and its antero-posterior dimension, were both negatively correlated with the arterial flicker response (Rs = -0.34, p = 0.003; Rs = -0.33, p = 0.004, respectively). From tissue Doppler parameters, the left ventricular filling index E/e' negatively correlated with AVR (arteriovenous ratio) values (Rs = -0.36, p = 0.002). CONCLUSIONS: We revealed that systolic and diastolic function of the left ventricle in hypertensive patients is associated with retinal microvascular function.

Cell therapy raises hope to reduce the harmful effects of acute myocardial ischemia. Stem and progenitor cells (SPCs) may be a valuable source of trophic factors. In this study, we assessed the plasma levels of selected trophic factors in patients undergoing application of autologous bone marrow (BM)-derived, lineage-negative (Lin-) stem/progenitor cells into the coronary artery in the acute phase of myocardial infarction. The study group consisted of 15 patients with acute myocardial infarction (AMI) who underwent percutaneous revascularization and, afterwards, Lin- stem/progenitor cell administration into the infarct-related artery. The control group consisted of 19 patients. BM Lin- cells were isolated using immunomagnetic methods. Peripheral blood was collected on day 0, 2, 4, and 7 and after the first and third month to assess the concentration of selected trophic factors using multiplex fluorescent bead-based immunoassays. We found in the Lin- group that several angiogenic trophic factors (vascular endothelial growth factor, Angiopoietin-1, basic fibroblast growth factor, platelet-derived growth factor-aa) plasma level significantly increased to the 4th day after myocardial infarction. In parallel, we noticed a tendency where the plasma levels of the brain-derived neurotrophic factor were increased in the Lin- group. The obtained results suggest that the administered SPCs may be a valuable source of angiogenic trophic factors for damaged myocardium, although this observation requires further in-depth studies.

Polymyositis (PM) is an autoimmune disease characterized by the involvement of multiple internal organs, including the cardiovascular system. The involvement of heart is observed in up to 75% of patients with PM. Conduction and rhythm disorders are one of the most common cardiological abnormalities in these patients. The presented clinical case is the patient where ventricular arrhythmia (in the form of multiple premature ventricular extrasystoles) was the first symptom of polymyositis.

Pulmonary hypertension is a disease with diverse etiology. According to the New ESC guidelines, pregnancy is contraindicated for a patent with pulmonary hypertension and qualify such patent to class IV NYHA, regardless of the reason of hypertension. Pregnancy is revived for a patient with pulmonary hypertension despite of the fact that recent treatment methods including specific therapy with the endothelin receptor antagonistst (bosentan), phosphodiesterase inhibitors (sildenafil) and prostacyclin analogs (iloprost) were introduced. In the case of coincidence of pregnancy and pulmonary hypertension, patients should be managed in a center with expertise in pulmonary hypertension with all therapeutic options available.

Conduction disorders in women are often presented as sick sinus syndrome in comparison to men who have more often disturbances of AV conduction diseases and sinus carotid diseases. Nearly every heart disease with prevalence of ischeamic heart disease and idiopathic degenerative fibrotic process, which leads to reduction number of trigger cells, can result in conduction disorders. As a gold standard in treatment is pacemaker implantation with appropriate pacing mode, after exclusion a reversable reason of the disease.

Pregnancy is accompanied by a variety of cardiovascular changes in normal women, and these changes can increased incidence of maternal cardiac arrhythmias. Supraventricular and ventricular arrhythmias reguiring treatment are rarely seen during pregnancy in healthy women. Structural cardiac defects or residual defects after repair may contribute to the occurrence of clinically relevant arrhythmias. Arrhythmias during pregnancy include a wide spectrum. The most common are simple ventricular and atrial ectopy, sinusal tachycardia and supraventricular tachycardia. The foetus may suffer both haemodynamic alternations and adverse effects of the treatment (teratogenic risk, foetal growth and development). The management of arrhythmias in pregnant women is similar to that taken in patients who are not pregnant.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease resulting from impaired patency of the pulmonary arteries by a clot, and the treatment method of choice is pulmonary endarterectomy (PEA). In inoperable patients, balloon pulmonary angioplasty (BPA) is recommended, but we need to implement pharmacological bridge therapy to BPA in some cases. We report a case of a 38-year-old male diagnosed with CTEPH, disqualified from PEA due to comorbidity, who developed right ventricular (RV) failure. The case shows a complex pharmacological treatment method that can be successfully used as an effective bridge therapy to BPA in patients with CTEPH and severe RV dysfunction, disqualified from surgery.
RESUMEN
BACKGROUND: People living with human immunodeficiency virus (HIV) (PLWH) have increased risk of developing diastolic dysfunction (DD) and heart failure with preserved ejection fraction (EF). In this observational study, we evaluated DD and left ventricular hypertrophy (LVH) in PLWH receiving antiretroviral therapy (ART) with undetectable viremia. METHODS: We conducted an observational study. All participants underwent transthoracic echocardiography to assess chamber size and systolic and diastolic function. RESULTS: Most patients showed concentric remodeling without LVH. All patients had normal left ventricle systolic function (EF median 61.3%, interquartile range: 57.8-66.2). None fulfilled the DD criteria, while two patients (6%) had undetermined diastolic function. Twenty percent (n = 7) of patients had an enlarged left atrium (left atrium volume index [LAVI] > 34 cm3/m2). These patients had a significantly lower CD4+ count (771.53 ± 252.81 vs. 446.00 ± 219.02, p = 0.01) and higher relative wall thickness (0.50 ± 0.05 vs. 0.44 ± 0.06, p = 0.03). Patients without immune restoration above 500 cells/µL had significantly higher LAVI (33.92 ± 6.63 vs. 24.91 ± 7.03, p = 0.01). CONCLUSIONS: One-fifth of patients had left atrial enlargement associated with worse immune restoration during ART treatment. The mechanism of left atrial enlargement and its association with cardiovascular risk require further investigations.
RESUMEN
BACKGROUND: Left ventricular diastolic dysfunction (LV DD) is the most dominant cause of heart failure with preserved ejection fraction (HFpEF) worldwide. This pathological condition may contribute to postcapillary pulmonary hypertension (pcPH) development. Hypoxemia, often observed in pcPH, may significantly negatively impact the course of hospitalization in patients after cardiac surgery. The aim of our study was to investigate the impact of LV DD on the frequency of postoperative respiratory adverse events (RAE) in patients undergoing Coronary Artery Bypass Grafting (CABG). METHODS: The left ventricular (LV) diastolic function was assessed in 56 consecutive patients admitted for CABG. We investigated the relationship between LV DD and postoperative respiratory adverse events (RAE) in groups with normal LV diastolic function and LV DD stage I, II, and III. RESULTS: Left ventricular diastolic dysfunction stage I was observed in 11 patients (19.6%) and LV DD stage II or III in 19 patients (33.9%). Arterial blood partial pressure of oxygen (PaO2) to the fraction of inspired oxygen (FiO2) index during postoperative mechanical ventilation was significantly lower in LV DD stage II or III than in the group with normal LV diastolic function. Patients with DD stage II or III had a higher occurrence of postoperative pneumonia than the group with normal LV diastolic function. CONCLUSIONS: Left ventricular diastolic dysfunction is widespread in cardiac surgery patients and is an independent risk factor for lower minimal PaO2/FiO2 index during mechanical ventilation and higher occurrence of pneumonia.
RESUMEN
BACKGROUND: An adequate interlesion distance (ILD) applied during point-by-point pulmonary vein (PV) isolation for atrial fibrillation (AF) has never been established. We hypothesized that maximum tolerated ILD may differ between PV regions and may influence long-term ablation outcomes. METHODS: A total of 260 AF patients underwent PV isolation with 3D electroanatomical platform. Postablation, ILD values were classified into 5 groups (6-5.5 mm, 5.5-5.0 mm, 5.0-4.5 mm, 4.5-4.0 mm and <4.0 mm); the number of tags in each group was calculated and correlated with postablation AF recurrence (AFR). All measurements were performed globally for the entire encirclement around each individual PV and regionally for designated PV anatomic segments. RESULTS: Single-procedure freedom from AF was 81% for paroxysmal and 66% for persistent AF at 12 months. Global analysis showed that AFR was not related to median ILD nor the number of lesions within each ILD tag group for any PV. Segmental analysis showed that AFR was not related to median ILD. However, the presence of tags from the 5.5-6.0 mm ILD group located on the posterior aspect of right upper PV (RUPV) correlated with AFR. This was confirmed in a multivariable logistic regression model. CONCLUSIONS: Maximum tolerated ILD of 6.0 mm translated into well-accepted ablation results. However, the study suggests that it may be inadequate at the posterior aspect of RUPV.
RESUMEN
We describe a case of a patient with the history of a monomorphic postinfarction ventricular tachycardia that exhibited a right bundle branch block morphology and a superior axis. Because of electrical and hemodynamic instability of arrhythmia, classical mapping techniques were not applied. An electroanatomic voltage map during sinus rhythm was performed. A Purkinje potential (PP) preceding the QRS complex was recorded at posteroseptal area of a scar. Radiofrequency energy delivery at sites where a PP was detected resulted in a successful ablation.

AIM: To assess the incidence of mitral valve prolapse in patients with newly diagnosed primary open angle glaucoma. METHODS: The study included 12 patients without any other comorbidities or taking any general or local medications. Each patient underwent a full ophthalmological examination with visual field assessment and optical computed tomography of the macula and optic nerve head. Carotid Doppler ultrasound was performed to exclude impaired blood flow in this region and transthoracic echocardiography with assessment of the function and morphology of the heart valves. RESULTS: In the study group, mitral valve prolapse was found in seven patients (58.3%), while mitral valve regurgitation in 11 patients (91.7%). One case of normal pressure glaucoma and four cases of juvenile glaucoma were diagnosed. There were also other risk factors for glaucoma: myopia (58.3%), migraine headaches (41.7%), a positive family history of glaucoma (16.7%). CONCLUSION: Mitral valve prolapse could be indicated as a new risk factor for glaucoma. It seems reasonable to conduct screening tests for glaucoma in patients with mitral valve prolapse in the course of echocardiography.
RESUMEN
BACKGROUND: Lung transplantation (LuTx) is a challenge when right heart function fails. Mechanical circulatory support (MCS) is then necessary. METHODS: We aimed to investigate whether preoperative transthoracic echocardiography (TTE) can predict MCS use and help to exclude the sickest patients. Between 2011 and 2018, 52 patients at our institution received LuTx and qualified for this study: 35 bilateral, 16 single, 1 lobar [1] and 1 retransplantation procedure. Of these, 22 were operated using MCS and 30 without MCS. The patients were aged between 18 and 65 years, and 23 were women. The indications were lung fibrosis for 18 patients, chronic obstructive lung disease for 16, cystic fibrosis for 15, primary pulmonary hypertension for 2 and bronchiectasis for 1. TTE was performed up to 30 days before treatment and 1 to 7 days after. RESULTS: Patients undergoing MCS versus patients not undergoing MCS: preoperative right ventricular systolic pressure 56.5 (30) vs 37.8 (11.5) mm Hg (P = .03); tricuspid regurgitation pressure gradient 48.7 (27) vs 30.2 (10.8) mm Hg (P = .015); tricuspid annular plane systolic excursion 17.8 (4.3) vs 19.9 (2.8) mm Hg (P = .04); pulmonary artery diameter 27.5 (5.2) vs 23.9 (4.1) mm (P = .004); age 41.9 (14.1) vs 54.3 (11.8) years (P = .001). Patients who were Dead versus patients who were alive pulmonary valve acceleration time of 82.8 (24.1) vs 104.9 (27.2) ms (hazard ratio [HR] = 0.959, 95% confidence interval [CI] = 0.923-0.996 per ms, P = .02) and pulmonary artery diameter of 28.9 (5.8) vs 24.4 (4.1) mm HR = 1.225, 95% CI = 1.028-1.460 per 1 mm, P = .016 were predictors of death. CONCLUSIONS: Preoperative TTE parameters: right ventricular systolic pressure, tricuspid regurgitation pressure gradient, tricuspid annular plane systolic excursion, and pulmonary artery diameter predicted MCS use during LuTx. Certain values of valve acceleration time and pulmonary artery diameter could help discern LuTx qualification.

BACKGROUND: Pulmonary hypertension (PH) is an independent risk factor of increased morbidity and mortality in cardiac surgery patients (CS). The most common cause underlying PH is left ventricular (LV) diastolic dysfunction. This study aimed to evaluate the echocardiographic probability of PH in patients undergoing CS and its correlation with postoperative respiratory adverse events (RAE). METHODS: The echocardiographic probability of PH and its correlation with LV diastolic dysfunction was assessed in 56 consecutive adult patients who were qualified for coronary artery bypass grafting (CABG). Later, the postoperative RAE (such as pneumonia, pulmonary congestion, or hypoxemia), the length of intensive care unit (ICU) treatment and mortality in groups with moderate or high (PH-m/h) and low (PH-l) probability of pulmonary hypertension were examined. RESULTS: PH-m/h was observed in 29 patients, of whom 65.5 % had LV diastolic dysfunction stage II or III. A significantly higher occurrence of RAE was observed in the PH-m/h group as compared to the PH-l group. There were no differences between the PH-m/h and PH-l patient groups regarding the in-hospital length of stay or mortality. CONCLUSIONS: High or intermediate probability of PH is common in cardiac surgical patients with left ventricular diastolic dysfunction and correlates with respiratory adverse events.
RESUMEN
BACKGROUND: Abdominal obesity, together with atherogenic dyslipidemia, increased blood pressure and impaired glucose tolerance, was included in the components of metabolic syndrome identifying patients at high risk of cardiovascular diseases. Subcutaneous adipose tissue is a buffer for dietary fatty acids (FAs). It was reported that the fatty acid composition of adipose tissue reflects the dietary intake of FAs in the previous 6 to 9 months. Therefore, we decided to evaluate the early and long-term metabolic effects of lipocavitation and/or thermolipolysis on abdominal fat reduction. MATERIAL AND METHODS: The study population comprised 60 women. Subjects were randomly allocated into one of three subgroups, 20 women per subgroup, and each subgroup received 10 treatments with ultrasound (U group), radiofrequency (RF group), or combined radiofrequency and ultrasound (RF/U group) for the abdominal region. Treatments were provided three times a week using the multifunctional device (Professional Beauty Equipment, HEBE, Warsaw, Poland). Each treatment to reduce adipose tissue, regardless of the method used, involved 20 min of massage with the dedicated applicator head on a rectangular 20 cm × 10 cm area of the abdominal region. Fatty acid composition and biochemical and anthropometric parameters were measured before the first, after 10 treatments and 6 months after the last treatment. RESULTS AND DISCUSSION: The series of 10 treatments to reduce abdominal adipose tissue using ultrasound, radiofrequency or both methods resulted in a cosmetic effect which was reflected in weight loss and BMI reduction. Reduced waist circumference was also found in patients who received radiofrequency or two types of intervention (RF + U) but not ultrasound treatments. The long-term cosmetic effect (lasting for at least 6 months) was achieved only with RF treatment and was reflected in reduced body weight, BMI and waist circumference. None of the treatments had a direct, short or long-term effect on the lipid profile, insulin resistance markers, inflammation markers, or blood pressure. Consequently, did not modify the risk of cardiovascular diseases.

BACKGROUND: Balloon pulmonary angioplasty (BPA) is a promising therapy for patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are ineligible for pulmonary endarterectomy. AIMS: The present study aimed to evaluate the safety and efficacy of BPA for CTEPH using the first multicentre registry of a single European country. METHODS: Data were obtained from the Database of Pulmonary Hypertension in the Polish Population (NCT03959748), a prospective, multicentre registry of adult and paediatric pulmonary arterial hypertension (PAH) and CTEPH, for a total of 236 patients with confirmed CTEPH (124 women; mean age 67 years) who underwent 1,056 BPA procedures at eight institutions in Poland. RESULTS: In 156 patients who underwent follow-up assessments after a median of 5.9 (IQR: 3.0-8.0) months after final BPA, the mean pulmonary arterial pressure decreased from 45.1±10.7 to 30.2±10.2 mmHg (p<0.001) and pulmonary vascular resistance from 642±341 to 324±183 dynes (p<0.001), and the six-minute walking test (6MWT) improved from 341±129 to 423±136 m (p<0.001). Pulmonary injury related to the BPA procedure occurred in 6.4% of all sessions. Eighteen patients (7.6%) died during follow-up, including 4 (1.7%) who died within 30 days after BPA. Overall survival was 92.4% (95% confidence interval [CI]: 87.6%-94.9%) three years after the initial BPA procedure. CONCLUSIONS: This multicentre registry confirmed significant improvement of haemodynamic, functional, and biochemical parameters after BPA. Complication rates were low and overall survival comparable to the results of another registry. Therefore, BPA may be an important therapeutic option in patients with CTEPH in Poland.
