Aim To study the antianginal and heart rate slowing effects in patients with stable angina (SA) who failed to achieve the heart rate (HR) goal and were switched from the beta-blocker (BB) metoprolol tartrate to a combination of metoprolol tartrate and ivabradine.Materials and methods The study included 54 patients with SA not higher than functional class (FC) III (35 (64.8 %) men and 19 (35.2 %) women) aged 59 [48; 77] years. Prior to the study start and at 4 and 8 weeks of follow-up, electrocardiography (ECG) and 24-h ECG monitoring (24h-ECGM) were performed for all patients. The follow-up period duration was 8 weeks. The antianginal and heart rate slowing effects of therapy were clinically evaluated by a decrease in frequency of anginal attacks and patients’ requirement for nitrates, a decrease in HR, and the effect on 24h-ECGM indexes characterizing myocardial ischemia. At the first stage, all patients were prescribed metoprolol tartrate (Egilok®, Egis, Hungary) 25 mg twice a day. Patients with resting HR still higher than 70 bpm after 4 weeks of treatment were switched from metoprolol tartrate to a fixed ivabradine/metoprolol combination (Implicor®, Servier, France) 5 / 25 mg twice a day. Thus, based on achieving/ non-achieving the HR goal, two groups of patients were formed. Statistical analysis was performed with a STATISTICA 10,0 software package.Results After 4 weeks of therapy with metoprolol tartrate 25 mg twice a day, 18 (33.3%) patients of group 1 achieved the HR goal of 70 bpm, while  36 (66.7%) patients of group 2 did not achieve the goal. For further correction of HR, patients of group 2 were switched from metoprolol tartrate to ivabradine/metoprolol 5 / 25 mg twice a day. After 4 weeks of the ivabradine/metoprolol treatment, 31 (86.1 %) patients achieved the HR goal with median resting HR of 62 [56; 70] bpm. The number of angina attacks decreased from 6 [3; 8] to 2 [1; 3] per week (р<0.001). 24hECGM showed that the mean diurnal HR decreased from 81 [76; 96] to 66 [56; 76] bpm (р<0.001); mean night HR decreased from 69 [73; 80] to 52 [43; 60] bpm (р=0.012); and the ischemic ST segment depression was absent.Conclusion Only 33.3% of patients with stable angina achieved the HR goal on metoprolol tartrate 25 mg twice a day. Supplementing the beta-blocker metoprolol tartrate at the same dose with ivabradine allowed 86.1% of patients to achieve the HR goal and exerted a pronounced anti-anginal effect.

Abstract Background The prevalence of chronotropic incompetence (CI) in heart failure (HF) population is high and negatively impacts prognosis. In HF patients with an implanted cardiac resynchronisation therapy (CRT) device and severe CI, the effect of rate adaptive pacing on patient outcomes is unclear. Closed loop stimulation (CLS) based on cardiac impedance measurement may be an optimal method of heart rate adaptation according to metabolic need in HF patients with severe CI. Purpose This is the first study evaluating the effect of CLS on the established prognostic parameters assessed by the cardio-pulmonary exercise (CPX) testing and on quality of life (QoL) of the patients. Methods A randomised, controlled, double-blind and crossover pilot study has been performed in CRT patients with severe CI defined as the inability to achieve 70% of the age-predicted maximum heart rate (APMHR). After baseline assessment, patients were randomised to either DDD-CLS pacing (group 1) or DDD pacing at 40 bpm (group 2) for a 1-month period, followed by crossover for another month. At baseline and at 1- and 2-month follow-ups, a CPX was performed and QoL was assessed using the EQ-5D-5L questionnaire. The main endpoints were the effect of CLS on ventilatory efficiency (VE) slope (evaluated by an independent CPX expert), the responder rate defined as an improvement (decrease) of the VE slope by at least 5%, percentage of maximal predicted heart rate reserve (HRR) achieved, and QoL. Results Of the 36 patients enrolled in the study, 20 fulfilled the criterion for severe CI and entered the study follow-up (mean age 68.9±7.4 years, 70% men, LVEF=41.8±9.3%, 40%/60% NYHA class II/III). Full baseline and follow-up datasets were obtained in 17 patients. The mean VE slope and HRR at baseline were 34.4±4.4 and 49.6±23.8%, respectively, in group 1 (n=7) and 34.5±12.2 and 54.2±16.1% in group 2 (n=10). After completing the 2-month CPX, the mean difference between DDD-CLS and DDD-40 modes was −2.4±8.3 (group 1) and −1.2±3.5 (group 2) for VE slope, and 17.1±15.5% (group 1) and 8.7±18.8% (group 2) for HRR. Altogether, VE slope improved by −1.8±2.95 (p=0.31) in DDD-CLS versus DDD-40, and HRR improved by 12.9±8.8% (p=0.01). The VE slope decreased by ≥5% in 47% of patients (“responders to CLS”). The mean difference in the QoL between DDD-CLS and DDD-40 was 0.16±0.25 in group 1 and −0.01±0.05 in group 2, resulting in an overall increase by 0.08±0.08 in the DDD-CLS mode (p=0.13). Conclusion First results of the evaluation of the effectiveness of CLS in CRT patients with severe CI revealed that CLS generated an overall positive effect on well-established surrogate parameters for prognosis. About one half of the patients showed CLS response in terms of improved VE slope. In addition, CLS improved quality of life. Further clinical research is needed to identify predictors that can increase the responder rate and to confirm improvement in clinical outcomes.

Aim: to compare the antianginal and pulse slowing effects, the impact on the ectopic myocardial activity as well as the safety of the treatment with beta - adrenoblocker bisoprolol, calcium antagonist verapamil and the combination of bisoprolol with amlodipine in patients with stable angina (SA) and bronchial asthma (BA). Materials and methods. The study included 90 patients with SA II-III functional class (FC) having concomitant persistent asthma of moderate severity, controlled, without exacerbation. The patients were divided into three groups with 30 individuals in each one depending on the main antianginal drug prescribed. Group 1 patients received a cardio - selective beta - adrenergic blocker bisoprolol (Concor) at the dose of 5 mg/day, patients of group 2 were treated by a calcium antagonist verapamil at the dose of 240 mg/day, patients of group 3 received combined therapy with bisoprolol at the dose of 5 mg/day and amlodipine at the dose of 5 mg/day given as a fixed combination (Concor AM 5/5). All the patients were investigated by the methods of daily ECG monitoring and respiratory function study (RFS) in addition to physical examination at baseline and after 4 weeks of treatment. Results. After 4 weeks of treatment, patients of group 1 and group 3 did not complain of angina attacks and did not use nitroglycerin unlike patients of group 2. The achieved heart rate (HR) in group 1 patients was 68.6±8.5 beats/min, in group 2 - 74.3±5.6 beats/min, in group 3 - 67.3±4.8 beats/min. A significant decrease in the number of supraventricular and ventricular extrasystoles occurred in patients of group 1 and group 3 only. Thus, the pulse slowing, antianginal, antiischemic and antiarrhythmic effect of the calcium antagonist verapamil, even at the dose of 240 mg/day, is not always sufficient for the patients with SA II-III FC and concomitant BA, unlike therapy with the inclusion of beta - blocker bisoprolol. During the study there was no registered deterioration in the indices of bronchial patency according to the RFS data in the patients of all three groups. Conclusion. In patients with coronary artery disease and concomitant asthma, all three types of pulse slowing therapy do not have any negative effects on bronchial patency. Therapy with the inclusion of beta - blockers (bisoprolol or its combination with amlodipine), in contrast to verapamil, reliably reduces heart rate and the number of supraventricular and ventricular extrasystoles in addition to a good antianginal effect.

Abstract Objective To study the incidence of side effects from muscle tissue during therapy with atorvastatin at various doses in patients with acute ST-segment elevation myocardial infarction (STEMI) during 48 weeks of follow-up. Methods The study included 115 STEMI patients aged 30 to 65 years (mean age 51.7±9.5 years). Patients were randomized to atorvastatin treatment groups. Group 1 included 59 people who took atorvastatin 80 mg / day; group 2 - 56 patients who received moderate doses of atorvastatin. The compared persons were matched by age, sex, and anthropometric data. Initially on the 7–9th days, after 24 and 48 weeks of follow-up, the CPK-MB serum level was analyzed. Muscle damage was assessed after 5–6, 24, 48 weeks of follow-up according to the development of the following symptoms: pain, fatigue, muscle weakness, decreased physical activity - on a 10-point scale. Results The CPK-MB level in the 1st group initialy was 701.5 [95% CI 391; 1012] U / L, after 24 weeks - 162.8 [95% CI 130.2; 195.4] U / L (p&lt;0.001), after 48 weeks - 205.6 [95% CI 134.8; 276.4] U / L (p&lt;0.001). In group 2, the dynamics of CPK-MB: on days 7–9 - 522.7 [95% CI 115.8; 755.1 U / L, after 24 weeks - 141.4 [95% CI 122.6; 160.3] U / L (p=0.0004), after 48 weeks - 150.5 [95% CI 123.9; 177.1] U / L (p=0.0003). A detailed analysis in four patients of the 1st group revealed an increase in CPK-MB &gt;4 upper limit of normal (ULN) after 48 weeks of follow-up (6.8%). Moreover, symptoms of muscle damage against the background of pathological CPK-MB values were observed only in two people (3.4%). In patients of the 2nd group after 24–48 weeks of therapy with atorvastatin, there was no increase in CPK-MB &gt;4 ULN. In addition, there were no cases of drug withdrawal in any of the groups due to an increase in CPK-MB&gt;10 ULN. Clinical symptoms of muscle damage after 5–6th, 24th and/or 48th weeks of follow-up were diagnosed in the 1st group in 41 patients (69.5%), in the 2nd group - in 31 people (55%) (p=0.11). Conclusion In STEMI patients on the background of 48-week therapy with atorvastatin, no serious adverse effects on the muscle tissue were revealed, which testifies in favor of the safety of high-dose statin therapy. The incidence of myalgia did not depend on the dose of the drug. FUNDunding Acknowledgement Type of funding sources: None.

This study aimed to investigate electrocardiographic changes in dogs aged 5 years or more submitted to two anesthetic combinations: atropine, levomeprazine, thiopental and halothane (ALTH), and atropine, tiletamine and zolazepam (ATZ). Forty dogs (24 males/16 females) weighing 5-24kg, were used. Dogs had no cardiac problems and were submitted to tartarectomy. All animals were submitted to two electrocardiograms (ECG), one before anesthesia and other immediately before surgery. The dogs were divided into two groups: group 1 received ALTH and group 2 received ATZ. Alterations in the ST segment, T wave, cardiac rhythm and a significant reduction of vagal tonus index were observed in both groups, but in group 2 a significant reduction of the PR and QT intervals and an increase in heart rate were also observed. These data suggest that the ALTH combination caused fewer changes in the ECG than the ATZ combination.

Few studies have examined the utility of serial echocardiography in the evaluation, management, and prognosis of patients with pulmonary arterial hypertension (PAH). Therefore, we sought to evaluate the prognostic significance of follow-up tricuspid annular plane systolic excursion (TAPSE) in PAH. We prospectively studied 70 consecutive patients with PAH who underwent baseline right heart catheterization (RHC) and transthoracic echocardiogram, who survived to follow-up echocardiogram after initiation of PAH therapy. Baseline TAPSE was 1.6 ± 0.5 cm which increased to 2.0 ± 0.4 cm on follow-up ( P < 0.0001). The cohort was dichotomized by TAPSE at one-year follow-up: Group 1 (n = 37): follow-up TAPSE ≥ 2 cm; Group 2 (n = 33): follow-up TAPSE < 2 cm. Group 1 participants were significantly more likely to reach WHO functional class I–II status and achieve a higher six-minute walk distance on follow-up. Of the 68 patients who survived more than one year, 18 died (26.5%) over a median follow-up of 941 days (range, 3–2311 days), with significantly higher mortality in Group 2 versus Group 1 (41.9% vs. 13.5%; P = 0.003). While baseline TAPSE stratified at 2 cm did not predict survival in this cohort, TAPSE ≥ 2 cm at follow-up strongly predicted survival in bivariable models (hazard ratio, 0.21; 95% confidence interval, 0.08–0.60). In conclusion, follow-up TAPSE ≥ 2 cm is a prognostic marker and potential treatment target in a PAH population.

Aim: to study the changes in heart rate variability (HRV) in patients with anxiety and depressive disorders who suffered acute coronary syndrome (ACS) and to determine the effects of antidepressant agomelatine on HRV and sleep quality during six-month follow up.Material and Methods. The study included 54 people with ACS, anxiety, and depressive disorders. Patients were randomly assigned to two groups. Antidepressant agomelatine 25 mg/day was administered to patients of group 1 in addition to standard therapy for ACS; group 2 received placebo. Twenty four-hour Holter ECG monitoring, HRV study, mental status monitoring, and sleep quality assessment were performed during hospitalization and at six-month follow up.Results. Patients of both groups had clinically significant anxiety, subclinical depression, and insomnia of varying severity. According to Holter monitoring data, all patients had decline in HRV parameters. After six months, anxiety and depression significantly improved in patients administered with agomelatine; these patients had sleep normalization and improved HRV. The comparison group did not have similar changes.Conclusion. Additional administration of agomelatine 25 mg/day to patients with anxiety and depressive disorders after ACS resulted in improvement of mental status, heart rate variability, and sleep quality. Due to the absence of pro-arrhythmogenic effects, administration of agomelatine allows to correct anxiety-depressive disorders in patients with ACS.

The aim – to evaluate the efficacy and safety of preparation of morpholinium salt of thiazotic acid in patients with stable angina in an open-label clinical non-randomized post-marketing study.Materials and methods. The study EPASS included 30 patients aged an average of (73.1±1.8) years with a diagnosis of coronary heart disease, stable angina pectoris, functional class II–III. All patients in addition to the basic therapy received the study drug (SD) – Antares, solution for injection («Галичфарм», Ukraine) – at a dose of 50 mg/ml 4 ml of solution intramuscularly 2 times a day at a daily dose of 400 mg for 14 days. Then the patients took SD tablets – Antares, tablets («Київмедпрепарат», Ukraine) – 200 mg three times a day at a daily dose of 600 mg: 15 patients for 40 days and 15 patients for an average of 70 days. Patients underwent clinical and laboratory examination, daily monitoring of the electrocardiogram with calculation of frequent and spectral parameters of heart rate variability (HRV), transthoracic echocardiography, test with a 6-minute walking distance (6MWD).Results and discussion. At the end of the course of treatment, all patients noted an improvement in general condition, a decrease in the intensity of pain and shortness of breath. In all patients, the walking distance increased significantly by an average of 21.6 %, in women – by an average of 19.8 %, in men – by an average of 22.7 %. Among patients with a median duration of treatment of 84 days, walking distance increased to a greater extent compared with that in the group of patients who received treatment for 54 days. The analysis of HRV parameters before the appointment of SD revealed a decrease in the activity of both the sympathetic and parasympathetic systems in the regulation of heart rate as a whole by group and depending on gender. After the course of treatment there was an increase in the total power of the spectrum and the restoration of the balance of autonomic regulation of the heart. Throughout the EPASS study, there was no early discontinuation of SD due to the development of serious adverse reactions; individual intolerance or hypersensitivity to thiazotic acid.Conclusions. The results of the EPASS study showed the antianginal efficacy of SD and increased exercise tolerance by the 6MWD test in patients with stable angina in real clinical practice, including in patients older than 79 years. An increase in exercise tolerance with the duration of the course of SD on average 84 days compared with that for 54 days was established. Demonstrated the safety of SD, the absence of side effects and the need to cancel it throughout the study period.
