The study included 27 patients with IPAH and 9 people who were in the control group. Both groups were comparable in age and sex. All patients underwent general clinical studies, biochemical blood tests to determine the level of N-terminal polypeptide of brain natriuretic hormone (NT-proBNP), 6-minute walk test, transthoracic and speckle-tracking echocardiography, Cardio-ankle vascular index (CAVI), right heart catheterization (RHC) using a Swan–Gantz catheter to determine central hemodynamic parameters.Results and discussion. According to echocardiography, in patients with IPAH, TAPSE, FAC, RIMP and S‘ of the right ventricle were significantly worse than in the control group, and the rates of global longitudinal strain of the right (RV GLS) and left ventricles (LV GLS) and longitudinal strain rate of the right ventricle (RV GLSR). Using correlation analysis, it was found that the RV GLS was most strongly correlated, among others, with the distance (p<0.001) and blood oxygen saturation (p<0.05) according to the 6-minute walk test, NT-proBNP (p<0.001), systolic pulmonary artery pressure according to echocardiography (p<0.001) and CAVI (p<0.001). In contrast, the highest correlation with direct hemody­­namic measurements was shown by two parameters: TAPSE – with cardiac index (p<0.05), pulmonary vascular resistance (PVR) (p<0.05), diastolic pressure in the pulmonary artery (p<0.05); and RIMP – with diastolic pulmonary artery pressure (p<0.001) and mean pulmonary artery pressure (p<0.05).Conclusions. According to our results, we can conclude that a comprehensive assessment of RV function using transthoracic and ST-echocardiography allows a more individualized assessment of patients with IPAH. ST-Echo can be used in PH reference centers for initial examination and follow-up of such patients. ST-Echo is a complex and time-consuming study, so our data did not demonstrate the feasibility of using this technique in routine practice for the initial assessment of patients with suspected IPAH.","PeriodicalId":23419,"journal":{"name":"Ukrainian Journal of Cardiology","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73909622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients were divided into 3 groups depending on body weight: group I included 52 patients with normal body weight (mean age – 60.83±11.94 years); group II – 51 patients with excess body weight (mean age – 62.04±8.55 years); group III – 55 patients with obesity I–III degree (mean age 60.96±11.31 years). 60 patients were selected in whose serum NT-proBNP and ST2 concentration were additionally determined twice, on admission and on the 10th day of treatment, using the test systems by Biomedica and Presage ST2 assay.Results and discussion. Patients were divided into 2 subgroups depending on the course of the disease: group A – 22 patients with STEMI complicated with acute HF with Killip class III–IV, acute left ventricular aneurysm, rhythm and conductivity disturbances; group B – 38 patients with STEMI without CV complications. At admission to the hospital mean levels of NT-proBNP were higher in patients with CV complications (612.8 [489.5; 860.4] pg/ml – group I) when compared to non CV complications patients (598.6 [326.6; 913.1] pg/ml – group II, p>0.05). On the 10th day of the hospitalization serum levels of NT-proBNP decreased in both groups of patients (р>0.01), regardless of the course of acute myocardial infarction: on 44.52 % – in group A and 68.24 % – in group B. However, it should be noted that the values of NT-proBNP in group A on the 10th day of observation significantly exceeded the corresponding indicators in group B (р>0,05). At admission to the hospital mean ST2 values were significantly higher in patients with diagnosed CV complications (61.1 [44.8; 133.6] ng/ml – A) compared with patients without complications (40.8 [33.1; 64.3] ng/ml – B, р>0.05). When re-determining the ST2 biomarker in both groups of patients there was a significant (р>0.001) decrease: to 23.7 [18.8; 28.3] ng/ml (A) and 24 [19.7; 28.7] ng/ml (B), respectively, without a significant difference between the groups.Conclusions. The biomarker ST2 can be considered as a predictor of cardiovascular complications in patients with STЕMI in the early postinfarction period. NT-proBNP values ​​in patients with complications in the early postinfarction period remain significantly higher on the 10th day of observation compared with those in patients without complications. The presence of obesity worsens the course of STЕMI: in such patients the values ​​of biomarkers NT-proBNP and ST2 are higher and complications are significantly more common in the early post-infarction period.","PeriodicalId":23419,"journal":{"name":"Ukrainian Journal of Cardiology","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82583735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with acute myocardial infarction (AMI) without persistent ST-segment elevation (NSTEMI) enrolled in the study (n=128) were divided into groups according to the time of revascularization (urgent or planned revascularization) and the method of revascularization (coronary stenting or shunting) on 5 groups, including the group of NSTEMI patients who did not undergo stenting. Group 1 consisted of patients (n=28) who underwent urgent coronary angiography and ad hoc stenting in the first 72 hours after the onset of symptoms. Group 2 included patients (n=61) who underwent coronary angiography and stenting routinely after 72 hours or more (up to several months of onset of symptoms). Group 3 included patients (n=12) who underwent routine coronary artery bypass grafting. Group 4 consisted of patients (n=27) who did not undergo revascularization after coronary angiography («control group»). And, finally, the 5th group, which consisted of patients of the above groups (n=101), who underwent any revascularization.Results and discussion. The effectiveness of treatment and the incidence of serious coronary events in NSTEMI patients significantly depend on the availability of percutaneous and surgical revascularization techniques in the treatment program. Supplementation of the revascularization procedure significantly improves the prognosis, significantly reduces the combined rate of MACE during the observation period of patients (up to 48 months) compared with the control group (p=0.000001).A direct comparison of the group of urgent coronary stenting (within 72 hours from the onset of symptoms) of NSTEMI patients with GRACE Score > 140 points, revealed a significant difference in the number of serious cardiovascular events at 48 months of follow-up (p>0.05), compared with the control group GRACE Score > 140.Conclusions. Long-term stenting results of NSTEMI patients at high risk of complications (emergency stenting group) did not take precedence over the results of treatment of stable NSTEMI patients (planned stenting group) after their effective stabilization on the background of optimal drug therapy. When comparing the MACE of these two groups, a weakly significant advantage (p>0.05) was found in the group of stabilized patients, which fully confirms the strategy of stratification of patients with unstable coronary blood flow to groups at risk of complications. However, urgent interventions are absolutely indicated for patients at high risk of complications in the first days after the onset of destabilization symptoms.","PeriodicalId":23419,"journal":{"name":"Ukrainian Journal of Cardiology","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87017356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AM is the drug of choice in many difficult clinical situations. Despite its high efficiency and unique antiarrhythmic activity in comparison with other classes of antiarrhythmic drugs, AM has the broadest spectrum of side effects and complications – both cardiac and extracardiac. AM and its metabolites are highly lipophilic, thus accumulating in large quantities in the liver, lungs, skin, adipose tissue, the eye cornea, as well as other organs. AM-induced pulmonary toxicity is one of the most serious AM`s side effects. The development of AM-induced dysfunction of the thyroid gland, liver and other organs, in most cases, does not lead to serious consequences, but in some situations the revealed side effects are the reason for discontinuation of the drug. A number of randomized trials have emphasized that severe side effects are mainly associated with the administration of high doses of AM, and therefore its use is often limited. It is noteworthy that over the half-century history of the use of AM, indications for its administration have significantly narrowed due to its high toxicity. In recent years, there has been a tendency to prescribe low doses of AM with regular monitoring of its effectiveness and the presence of side effects. The information presented in the review can be useful for the correct use of AM in clinical practice. The article also presents our own clinical observations of severe extracardiac side effects of AM. The complications mentioned above are most often associated with excessive intake of AM, and they can be avoided or minimized by the careful adherence to the minimum maintenance dose. According to up-to-date guidelines, before prescribing any antiarrhythmic drug, it is necessary to carefully weigh not only the expected direct effect, but also take into account its possible side effects and complications.","PeriodicalId":23419,"journal":{"name":"Ukrainian Journal of Cardiology","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89386743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Medication adherence was also evaluated, the therapy was corrected if necessary and the presence of side effects and adverse events was registered. We analyzed the levels of BP and HR at the beginning and at the end of the study, the percentage of achievement of the recommended levels of these indicators, the antianginal efficacy of treatment and adherence to therapy in patients with CAD and different degrees of hypertension after 4 weeks of treatment.Results and discussion. 2785 patient questionnaires were provided by doctors, 1747 patients were included in substudy. The mean age of the patients was 60.9±10.2 years old, men – 57.1 %, women – 42.9 %. The diagnosis of coronary artery disease was based on: chest pain – 554 (31.7 %), a history of documented myocardial infarction – 935 (53.5 %), coronary ventriculography – 536 (30.7 %), revascularization (CABG/stenting) – 344 (19.8 %) patients.

The study included 195 patients: IPAH was in 68 patients; PAH associated with connective tissue diseases (CTD) – in 21 patients; PAH associated with HIV infection – in 4 patients; PAH associated with portal hypertension (PH) – in 4 patients; PAH associated with congenital heart disease – in 25 patients; CTEPH – in 51 patients, pulmonary hypertension (PH) associated with left heart disease (LHC) – in 5 patients and 17 patients who were excluded from the diagnosis of PH. From 2014 to 2019, these patients underwent 220 procedures of right heart catheterization (RHC) in accordance with current European Guidelines. Also, all patients underwent echocardiographic examination and determined the gas composition of blood and indicators of acid-base balance using the ABL 735 analyzer, calculated the parameters of the affinity of hemoglobin to oxygen (p50).Results and discussion. The lowest level of arterial blood oxygen saturation was in the group of patients with PH due to LHD – 88.9 % (p<0.05); in other groups it averaged 94–97 %. The oxygen content in arterial blood was the lowest in the group of patients with PH due to LHD – 15.7 ml/L (p<0.05); in other groups this indicator was equal to 17.4–18.7 ml/L. The lowest oxygen saturation of mixed venous blood (SvO2) was in the PAH group associated with HIV – 58 % (p<0.05), and close to critical (< 65 %) SvO2 level was observed in the IPAH group – 66.3 %. CTEPH – 66.0 %. The highest level of this indicator was in the PAH group associated with portal hypertension – 81.1 %. The arterio-venous difference was highest in the PAH associated with HIV group – 5.6 ml/L, and the smallest in the PAH associated with PH group – 2 ml/L.

The most severe disorders of hemodynamics and oxygen transport were observed in the group of PAH patients associated with HIV compared with other forms of PAH and CTEPH. The IPAH and CTEPH groups were similar in terms of hemodynamics, despite a different pathophysiological mechanism. In the group of patients with PAH associated with CTD, the results of the RHC were slightly better than in the group of patients with IPAH, reflecting that the hemodynamic component is not the leading one for prognosis in these patients. Also, the performance of the right ventricle was significantly higher in patients with PAH compared with the group without PH.","PeriodicalId":23419,"journal":{"name":"Ukrainian Journal of Cardiology","volume":"95 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80450132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cross-sectional study consecutively enrolled and analyzed clinical, instrumental and laboratory data from 118 persistent AF patients with the duration of its episode more than 7 days, who underwent an electrical cardioversion. Patients were subdivided into groups with the duration of AF episode 8-89 days (n=58) and ≥ 90 days (n=60).Results and discussion. We observed a significant difference between the studied groups by the frequency of systolic dysfunction cases: 2 (3.5 %) vs. 12 (20.3 %) patients in AF episode duration < 90 and ≥ 90 days groups, respectively (p=0.008). According to transesophageal echocardiography data, we revealed the difference between the groups of comparison by the value of left atrial appendage flow velocity (43.5 cm/s vs. 37.0 cm/s, respectively; p=0.020). The difference between the studied groups by left atrial volume index did not reach the statistical significance (98 (80–110) vs. 99 (86–114) ml/m2, respectively; p=0.088). Besides, both studied groups were characterized by the prevalence of patients with moderate decrease of estimated glomerular filtration rate (eGFR) (60–89 mL/(min·1.73 m2)): 36 (62.1 %) cases in AF episode duration < 90 days, and 38 (63.3 %) – amongst patients with the duration ≥ 90 days. Furthermore, about one-third of patients in both studied groups presented with more pronounced eGFR decline (< 60 mL/(min·1.73 m2)): 16 (27.6 %) and 18 (30.0 %) cases in the groups with AF episode duration < 90 and ≥ 90 days, respectively.Conclusions. The groups of persistent AF patients with the AF episode duration < 90 and ≥ 90 days were comparable by the majority of clinical, instrumental and laboratory characteristics, including the severity of kidney dysfunction. The AF episode duration ≥ 90 days was associated with the higher frequency of left ventricular systolic dysfunction cases, as well as with worse left atrial appendage function","PeriodicalId":23419,"journal":{"name":"Ukrainian Journal of Cardiology","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87489486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
