RESUMO

OBJECTIVE: Despite several improvements in the management of heart failure (HF), it is still an incurable and a progressive disease. Several trials demonstrated that the process of inflammation may be responsible for initiation and progression of HF. The aim of the present study was to investigate the role of interleukin-33 (IL-33) in the pathogenesis of HF and to assess whether disease etiology and course of the disease affect the expression of cytokines. METHODS: The study included 155 (106 male and 49 female) patients with systolic HF with a mean left ventricle ejection fraction of 32.13+-12.8% and 60 (36 male and 24 female) healthy individuals. IL-33 concentrations were evaluated using enzyme-linked immunosorbent assay. RESULTS: The concentration of IL-33 was statistically significantly lower in patients with HF than in healthy subjects, 16.91 (0-81.00) pg/mL and 92.51 (33.61-439.61) pg/mL, respectively. Patients with HF with ischemic etiology had lower concentration of IL-33 (10.75 pg/mL) than subjects with HF with non-ischemic etiology (21.05 pg/mL). Patients with stable HF (10.46 pg/mL) had lower IL-33 levels than those with unstable HF (19.02 pg/mL). CONCLUSION: The concentrations of IL-33 were lower in patients with HF than in healthy controls, which may play an important role of above cytokine in HF development and progression. In addition, interleukin concentrations varied depending on the etiology and severity of the course of the disease.

RESUMO

BACKGROUND: The rate of cardiac device-related infective endocarditis (CDRIE) is increasing worldwide, but no detailed data are available for Poland. AIMS: We aimed to evaluate clinical, diagnostic, and therapeutic data of patients hospitalized due to CDRIE in 22 Polish referential cardiology centers from May 1, 2016 to May 1, 2017. METHODS: Participating cardiology departments were asked to fill in a questionnaire that included data on the number of hospitalized patients, number and types of implanted cardiac electrotherapy devices, and number of infective endocarditis cases. We also collected clinical data and data regarding the management of patients with CDRIE. RESULTS: Overall, 99 621 hospitalizations were reported. Infective endocarditis unrelated to cardiac device was the cause of 596 admissions (0.6%), and CDRIE, of 195 (0.2%). Pacemaker was implanted in 91 patients with CDRIE (47%); cardioverter­defibrillator, in 51 (26%); cardiac resynchronization therapy­defibrillator, in 48 (25%); and cardiac resynchronization therapy­pacemaker, in 5 (2.5%). The most common symptoms were malaise (62%), fever/chills (61%), cough (21%), chest pain (19.5%), and inflammation of the device pocket (5.6%). Cultures were positive in 77.5% of patients. The cardiac device was removed in 91% of patients. The percutaneous approach was most common for cardiac device removal. All patients received antibiotic therapy, and 3 patients underwent a heart valve procedure. Transesophageal echocardiography was performed in 80% of patients. The most common complication was heart failure (25% of patients). CONCLUSIONS: The clinical profile, pathogen types, and management strategies in Polish patients with CDRIE are consistent with similar data from other European countries. Transesophageal echocardiography was performed less frequently than recommended. The removal rate in the Polish population is consistent with the general rates observed for interventional treatment in patients with CDRIE.

RESUMO

BACKGROUND: Systemic artery to pulmonary artery fistulas (SA-PAFs), are extremely rare in people without congenital heart disease. In this group of patients pulmonary arterial hypertension was reported in the single case. Then, we describe a case of multiple SA-PAFs, which were the cause of severe nonreversible arterial pulmonary hypertension in a patient who had a right-sided pneumothorax 35 years earlier. CASE PRESENTATION: 52-year-old male Caucasian patient with echocardiographically confirmed pulmonary hypertension (PH) was admitted to cardiology department due to exertional dyspnea and signs of right ventricle failure. Routine screening for causes of secondary PH was negative. Right heart catheterization (RHC) confirmed a high degree arterial PH [mean pulmonary artery pressure (mPAP); 50,6 mmHg, pulmonary wedge pressure (PWP); 11,3 mmHg, pulmonary vascular resistance (PVR); 11,9 Wood's units (WU)] irreversible in the test with inhaled nitric oxide. Oxygen saturation (SaO2) of blood samples obtained during the first RHC ranged from 69.3 to 73.2%. Idiopathic pulmonary arterial hypertension was diagnosed. Treatment with inhaled iloprost and sildenafil was initiated. Control RHC, performed 5 months later showed values of mPAP (59,7 mmHg) and PVR (13,4 WU) higher in comparison to the initial measurement, SaO2 of blood obtained during RHC from upper lobe artery of the right lung was elevated and amounted 89.7%. Then, pulmonary arteriography was performed. Lack of contrast in the right upper lobe artery with the evidence of retrograde blood flow visible as a negative contrast in the right pulmonary artery was found. Afterwards, right subclavian artery arteriography detected a huge vascular malformation communicating with right upper lobe artery. Following computed tomography angiogram (angio-CT) additionally revealed the enlargement of bronchial arteries originated fistulas to pulmonary artery of right upper lobe. In spite of intensive pharmacological treatment, including the therapy of pulmonary hypertension and percutaneous embolisation of the fistulas, the patient's condition continued to deteriorate further. He died three months after embolisation due to severe heart failure complicated by pneumonia. CONCLUSION: Non-congenital SA-PAFs are extremely rare, however, they should be excluded in patients with pulmonary arterial hypertension and history of inflammatory or infectious disease of the lung and pleura, pneumothorax, cancer or Takayashu's disease and after chest trauma.

RESUMO

BACKGROUND: Heart failure (HF) has become an epidemic. A similar situation is also observed for atrial fibrillation (AF). The CHA2DS2-VASc score is one of the most useful tools for thromboembolic risk assessment. AIM: The aim of the study was to assess the prevalence of AF in patients with decompensated HF, who were divided into subgroups according to the CHA2DS2-VASc score. METHODS: We analysed the prevalence of AF in a group of 1108 patients (327 women) hospitalised due to HF decompensa- tion in medical centres of different referral levels. Twenty-one patients refused to participate in the registry. The data were collected from Polish centres included in the European Society of Cardiology Heart Failure Long-Term Registry. The recruit- ment period was from 2011 to 2014. The data were analysed retrospectively. Patients were divided into groups according to the CHA2DS2-VASC score. RESULTS: The study sample was characterised by a high occurrence of AF (44.3%), with the highest prevalence in patients with a CHA2DS2-VASC score ≥ 6 (61.3%, p = 0.01). CONCLUSIONS: The CHA2DS2-VASc score may be a useful tool for detecting patients with HF characterised by the highest risk of AF.

RESUMO

Background: Clinical short-term risk stratification is a recommended approach in patients with chest pain and possible acute myocardial infarction (AMI) to further improve high safety of biomarker-based rule-out algorithms. The study aim was to assess clinical performance of baseline concentrations of high-sensitivity cardiac troponin T (hs-TnT) and copeptin and the modified HEART score (mHS) in early presenters to the emergency department with chest pain. Methods: This cohort study included patients with chest pain with onset maximum of 6 h before admission and no persistent ST-segment elevation on electrocardiogram. hs-TnT, copeptin, and the mHS were assessed from admission data. The diagnostic and prognostic value for three baseline rule-out algorithms: (1) single hs-TnT < 14 ng/l, (2) hs-TnT < 14 ng/l/mHS ≤ 3, and (3) hs-TnT < 14 ng/l/mHS ≤ 3/copeptin < 17.4 pmol/l, was assessed with sensitivity and negative predictive value. Primary diagnostic endpoint was the diagnosis of AMI. Prognostic endpoint was death and/or AMI within 30 days. Results: Among 154 enrolled patients, 44 (29%) were classified as low-risk according to the mHS; AMI was diagnosed in 105 patients (68%). For ruling out AMI, the highest sensitivity and NPV from all studied algorithms were observed for hs-TnT/mHS/copeptin (100%, 95% CI 96.6-100, and 100%, 95% CI 75.3-100). At 30 days, the highest event-free survival was achieved in patients stratified with hs-TnT/mHS/copeptin algorithm (100%) with 100% (95% CI 75.3-100) NPV and 100% (95% CI 96.6-100) sensitivity. Conclusions: The combination of baseline hs-TnT, copeptin, and the mHS has an excellent sensitivity and NPV for short-term risk stratification. Such approach might improve the triage system in emergency departments and be a bridge for inclusion to serial blood sampling algorithms.

RESUMO

BACKGROUND: Various scores have been derived for the assessment of syncope patients in the emergency department (ED) but stay inconsistently validated. We aim to compare their performance to the one of a common, easy-to-use CHADS2 score. METHODS: We prospectively enrolled patients ≥ 40 years old presenting with syncope to the ED in a multicenter study. Early clinical judgment (ECJ) of the treating ED-physician regarding the probability of cardiac syncope was quantified. Two independent physicians adjudicated the final diagnosis after 1-year follow-up. Major cardiovascular events (MACE) and death were recorded during 2 years of follow-up. Nine scores were compared by their area under the receiver-operator characteristics curve (AUC) for death, MACE or the diagnosis of cardiac syncope. RESULTS: 1490 patients were available for score validation. The CHADS2-score presented a higher or equally high accuracy for death in the long- and short-term follow-up than other syncope-specific risk scores. This score also performed well for the prediction of MACE in the long- and short-term evaluation and stratified patients with accuracy comparative to OESIL, one of the best performing syncope-specific risk score. All scores performed poorly for diagnosing cardiac syncope when compared to the ECJ. CONCLUSIONS: The CHADS2-score performed comparably to more complicated syncope-specific risk scores in the prediction of death and MACE in ED syncope patients. While better tools incorporating biochemical and electrocardiographic markers are needed, this study suggests that the CHADS2-score is currently a good option to stratify risk in syncope patients in the ED.

RESUMO

Introduction During the last 20 years, there has been a considerable increase in the number of implanted implantable cardioverter­defibrillator (ICD) and cardiac resynchronization therapy (CRT) devices. However, there have been only single reports on clinical events, including rehospitalizations, in the long­term follow­up. Objectives We analyzed the baseline clinical characteristics, medical procedures used, and complications of patients with implantation of an ICD or CRT device. Moreover, we analyzed the causes of rehospitalization and the types of treatment used in the 12­month follow­up. Patients and methods Out of 1 208 440 hospitalizations of patients with cardiovascular diseases included in the SILCARD registry, hospitalizations with an ICD­9 code for an ICD or CRT device implantation between 2006 and 2016 were selected. Results The analysis included 12 147 patients with an ICD or CRT device. The total number of hospitalizations was 14 552. Over the years, a significant increase in the number of implanted devices and a higher percentage of CRT defibrillators was observed. Before the implantation, approximately 48.2% of patients underwent revascularization. In­hospital and 12­month mortality rates were 0.4% and 8.1%, respectively. Rehospitalizations due to cardiovascular causes were reported for approximately 40.3% of patients, with a significant reduction in the analyzed period. The most frequent cause of rehospitalization was heart failure (51.4%), while stable coronary artery disease and acute coronary syndromes constituted approximately 16% of the causes. In the 12­month follow­up, nearly every tenth patient was subjected to coronary angiography. Approximately 5% of patients required revascularization. Conclusions The relatively high rates of hospital readmissions and their causes indicate the need for a comprehensive care of patients before implantation of ICD or CRT devices and after discharge.

RESUMO

Background: In patients admitted with chest pain and suspected acute coronary syndrome (ACS), it is crucial to early identify those who are at higher risk of adverse events. The study aim was to assess the predictive value of copeptin in patients admitted to the emergency department with chest pain and nonconclusive ECG. Methods: Consecutive patients suspected for an ACS were enrolled prospectively. Copeptin and high-sensitive troponin T (hs-TnT) were measured at admission. Patients were followed up at six and 12 months for the occurrence of death and major adverse cardiac and cerebrovascular events (MACCE). Results: Among 154 patients, 11 patients died and 26 experienced MACCE. Mortality was higher in copeptin-positive than copeptin-negative patients with no difference in the rate of MACCE. Copeptin reached the AUC 0.86 (0.75-0.97) for prognosis of mortality at six and 0.77 (0.65-0.88) at 12 months. It was higher than for hs-TnT and their combination at both time points. Copeptin was a strong predictor of mortality in the Cox analysis (HR14.1 at six and HR4.3 at 12 months). Conclusions: Copeptin appears to be an independent predictor of long-term mortality in a selected population of patients suspected for an ACS. The study registration number is ISRCTN14112941.

RESUMO

25-hydroxyvitamin D (25(OH)D) plays a crucial role in human homeostasis. Its deficiency (vitamin D deficiency-VDD), being common in European population, combined with elevated concentration of parathyroid hormone (PTH), represents a vicious cycle of mechanisms leading to heart failure (HF). Despite several papers published in that field, the effect of VDD and PTH concentration on cardiovascular system remains unequivocal; thus, the aim of the study was to compare these data among HF and non-HF patients being prospectively enrolled into the study during hospital stay in the cardiology ward. Patients with HF had higher PTH concentration (85.0 ± 52.6 versus 64.5 ± 31.7, p ≤ 0.02) compared to non-HF patients. Mean PTH values were associated with the clinical status expressed by the New York Heart Association class (NYHA class) ("0"-66.04, "I"-56.57, "II"-72.30, "III"-85.59, and "IV"-144.37 pg/ml, p ≤ 0.00004). Interestingly, neither 25(OH)D (31.5 versus 29.7 ng/ml, p ≤ ns) nor phosphorus (P) (1.23 versus 1.18 mmol/l, p ≤ ns) nor total calcium (Ca2+) concentration (2.33 versus 2.37 mmol/l, p ≤ ns) differed among the groups. Reassuming PTH serum concentration in contrary to 25(OH)D, P and Ca2+ are significantly raised among the patients with HF and shows significant relationship with the clinical status expressed by the NYHA class.

RESUMO

AIM: Study was aimed to assess the real-world costs of manual thrombectomy (MT) in selected ST-segment elevation myocardial infarction patients with intracoronary thrombus (IT). METHODS: Study group (IT+) comprised 51 patients with MT applied and control group (IT-) comprised 56 patients without IT who underwent angioplasty alone. Costs comprised hospital care and cost of disposable materials used during primary angioplasty. RESULTS: Complex management of patients with IT is more expensive, though allows to achieve clinical outcomes comparable to low-risk ST-segment elevation myocardial infarction patients without IT. CONCLUSION: A complex pharmaco-interventional strategy, with glycoprotein IIB/IIIA inhibitor and MT, though more expensive, may prove cost-effective.

RESUMO

BACKGROUND: The controversy over electrotherapy for patients aged >80 years occurs already at the stage of qualification for this treatment type and concerns optimal device selection, the implantation strategy, and the overall benefit from pacemaker therapy. The group also has a considerable number of cardiovascular risk factors, and the data from the literature on the impact of the pacing mode on the remote prognosis of this group are ambiguous. OBJECTIVE: Assessment of the risk factors for death among patients with implanted pacemakers >80 years of age in a 4-year follow-up. METHODS: The study group consisted of 140 consecutive patients (79 women) aged 84.48 ± 3.65 years with single- or dual-chamber pacemakers implanted >80 years of age because of symptomatic bradycardia. In univariate and multivariate Cox regression analyses, demographic, echocardiographic, and laboratory parameters, pharmacotherapy, and factors related to the implanted device - i.e., indications, pacemaker type, and the implantation position of the tip of the right ventricular lead - were included. The endpoint was death for any reason in a 4-year follow-up. RESULTS: During follow-up, 68 patients (48.6%) died. Although atrial fibrillation with a slow ventricular response constituted 20% of the indications for implantation, 60.8% of the patients received a single-chamber system (VVI/VVIR). In the whole group, the multivariate Cox regression analysis showed both a favourable prognostic significance of DDD pacing system implantation (HR = 0.507; 95% CI: 0.294-0.876) and coexisting hypertension (HR = 0.520; 95% CI: 0.299-0.902). The risk factors were fasting glycaemia (HR = 1.180; 95% CI: 1.038-1.342) and, potentially, female sex (HR = 1.672; 95% CI: 0.988-2.830; p = 0.056). In the female subgroup a more favourable prognosis was related to the use of angiotensin-converting enzyme inhibitors (HR = 0.435; 95% CI: 0.202-0.933) and DDD pacemaker implantation (HR = 0.381; 95% CI: 0.180-0.806). In the male subgroup a more favourable prognosis was related to concerned patients with coexisting hypertension (HR = 0.349; 95% CI: 0.079-0.689). CONCLUSIONS: DDD mode pacing seems to serve as a factor which decreases mortality among patients aged >80 years in long-term follow-up. The potentially poorer prognosis for the female patients in this group may result from a combination of the dominant VVI pacing mode, potential propagation of atrial fibrillation, a low proportion of antithrombotic therapy, and sex-related predispositions to thromboembolic complications.

RESUMO

BACKGROUND: Acute myocardial infarction (AMI) might lead to left ventricular remodeling. Adequate myocardial perfusion is critical to prevent this adverse remodeling. Quantitative myocardial blush evaluator (QuBE) software, available on-line, is a simple analysis tool which enables the precise quantification of myocardial perfusion in the infarct area immediately after interventional treatment. The aim of this study was to assess whether the results of QuBE analysis might predict the development of HF in AMI patients in 3 year-long follow-up. METHODS: 95 patients with first AMI, single vessel coronary artery disease, Killip class I at presentation were enrolled in the study. Angiograms were reanalyzed using the on-line QuBE software. Data on heart failure development (ICD 10 codes I50) provided by the National Health Fund were considered as primary outcome. RESULTS: QuBE values ranged from 0.0 to 25.3 arbitrary units, mean value was 9.9 ± 5.2 arbitrary units. QuBE correlated positively with myocardial blush grade (MBG; Spearman R = 0.342 at p < 0.05). Multivariate Cox proportional hazard modeling, adjusted for initial TIMI flow, and TIMI thrombus grade indicated QuBE score (1 unit increase - HR 0.919, 95% CI 0.846-0.999, p = 0.049) and left ventricular ejection fraction at discharge (1% increase - HR 0.936, 95% CI 0.902-0.971, p = 0.000) as independent predictors of HF development. CONCLUSIONS: The QuBE assessment of myocardial perfusion allows the prediction of HF development in the post-infarction period in this highly selective group of patients.

RESUMO

Vitamin D and parathormone (PTH) are hormones regulating calcium and phosphorus homeostasis. The aim of the article is to summarize the current knowledge in the field and to assess its impact on heart failure (HF) pathogenesis. PTH serum concentration being frequently elevated in patients with HF has negative impact on circulatory system stimulating myocardial fibrosis, wall thickening and reninangiotensin-aldosterone system (RAAS) activity. PTH reacts with smooth muscle cells receptors mediating adrenergic and chronotropic activation resulting in increased oxidative stress, endothelial dysfunction, intracellular calcium overload and has negative influence on prognosis in chronic HF patients. Vitamin D, which deficiency is common in developed countries, has widely distributed receptors including myocardium, endothelium and smooth muscle cells. Being an antiproliferative agent vitamin D modulates RAAS, regulates natriuretic peptides and myosine expression, suppresses inflammatory cytokines activity, has antiarrhytmic properties and increases myocardial contractility. It decreases arterial pressure, inhibits atherosclerosis progression and plays a protective role against inflammation including viral infections of cardiotropic potential. Optimal vitamin D serum concentration has potential protective impact on cardiovascular system.

RESUMO

BACKGROUND: The following registry (Katowice-Zabrze retrospective registry) aimed to assess the influence of a chronic kidney disease (CKD) on long-term clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) using either first-generation (DES-I) or second-generation (DES-II) drug-eluting stents. METHODS: The study group consisted of 1,908 consecutive patients, of whom 331 (17.3%) had CKD. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/m2. We evaluated the major adverse cardiac and cerebral events (MACCE), i.e., the composite of death, myocardial infarction (MI), stroke, and target vessel revascularization at the 12-month follow-up. RESULTS: CKD patients had a lower left ventricular ejection fraction and more often a history of MI and PCI. Coronary angiography revealed that multivessel coronary artery disease, intracoronary thrombus, and extensive calcifications were more frequent in patients with CKD. However, the SYNTAX score did not vary between patients with or without CKD. There was a higher rate of in-hospital bleedings requiring blood transfusion in patients with CKD. At the 1-year follow-up, MACCE (17.8 vs. 12.6%, HR = 1.46 [95% CI 1.05-2.03], p = 0.009) and death (8.4 vs. 2.3%, HR = 3.9 [95% CI 2.0-7.5], p < 0.001) were more often observed in CKD patients. Multivariable Cox analysis revealed that CKD was an independent risk predictor of death after PCI at the 1-year follow-up (HR = 2.1 [95% CI 1.2-3.6], p = 0.004). In comparison to DES-I, the use of DES-II did not decrease the adverse effect of CKD on MACCE. CONCLUSION: CKD patients had an increased risk of in-hospital bleeding requiring blood transfusion and a higher risk of MACCE and death at the 12-month follow-up. The use of second-generation DES did not improve clinical outcomes in patients with CKD at the 12-month follow-up.

RESUMO

Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients with an anomalous left main coronary artery arising from the right sinus of Valsalva are presented. The diagnosis was made by coronary angiography, transesophageal echocardiography and multislice computed tomography (MSCT). We present two cases: the first patient with coronary abnormalities had accompanying venous anomaly of lower extremities and mitral valve prolapse as well. The second patient had a history of anterior wall myocardial infarction and angioplasty with stent implantation. The extraordinary passage of the left coronary artery between the pulmonary trunk and sternum, undetectable in coronarography, was discovered due to MSCT.

RESUMO

Dilated cardiomyopathy (DCM) is the third cause of heart failure and the most frequent cause of heart transplantation (HT). The value of biomarkers in prognostic stratification may be important to identification the patients for more advanced treatment. Assessment of serum Galectin-3 (Gal-3) and ST2 as biomarkers of unfavorable outcome (death and combined endpoint: HT or death or left ventricular assist device implantation) in stable DCM patients. 107 DCM patients age 39-56 years were included into the study and followed-up for mean 4.8 years. Gal-3 and ST2 concentrations were measured ELISA tests. Clinical data, treatment, laboratory parameters, NT-proBNP, Gal-3 and ST2 measured at time of inclusion were assessed as risk factors for reaching the study endpoints using log rank test and Cox proportional-hazards model. During follow-up 27 patients died, 40 achieved combined endpoint. ROC curves indicated cut-off value of ST2-17.53 ng/ml, AUC-0.65 (0.53-0.76) and of NT-proBNP-669 pg/ml, AUC 0.61 (0.50-0.73) for prediction of death. In multivariate analysis ST2 was predictor of death (HR per unit increase in log ST2 2.705, 95 % CI 1.324-5.528, P=0.006) and combined endpoint (HR per unit increase in log ST2 2.753, 95 % CI 1.542-4.914, P<0.001). NT-proBNP was predictive variable only for death in multivariate analysis. Gal-3 concentration was not associated with adverse outcome. ST2 but not Gal-3 may be useful for predicting adverse outcome in stable dilated cardiomyopathy patients.

RESUMO

INTRODUCTION: The recent studies demonstrated that obese heart failure patients have better prognosis - "obesity paradox". The aim of the study was to evaluate the relationship between body mass index (BMI), leptin and adiponectin concentrations and prognosis in patients with heart failure due to non ischeamic dilated cardiomyopathy (NIDCM). MATERIAL AND METHODS: 128 patients with NIDCM were included and followed-up for three years. Leptin and adiponectin were measured at baseline using commercially available ELISA tests. Clinical data, routine laboratory parameters, NT-proBNP were assessed as risk factors for reaching the study endpoints: urgent heart transplantation (B), death (C), or combined endpoint death or urgent heart transplantation (D). RESULTS: Patient with adverse outcome had lower BMI and higher NT-proBNP concentration. Leptin was significantly elevated in group C and adiponectin was higher in groups B and D than in survived patients. Patients with leptin concentration below median or with adiponectin concentration above median were more often transplanted in three years follow-up (p = 0.029, p = 0.022, respectively). The cumulative probability of death was greater in patients with concentration of leptin above median (p = 0.024). In the multivariable Cox proportional hazards analyses, increasing leptin and lower BMI were predictors of death. Adiponectin was associated with higher risk of heart transplantation. Both an inverse association of BMI and positive association of leptin and adiponectin with combined endpoint were discovered. Further adjustment to established risk factors abolished association between combined endpoint and BMI, and modestly attenuate with adiponectin and leptin concentration. CONCLUSION: Evaluation of adiponectin and leptin concentrations was more useful than BMI in prediction of unfavourable outcome in patients with NIDCM. (Endokrynol Pol 2017; 68 (1): 26-34).
