A machine learning approach to evaluate the impact of virtual balance/cognitive training on fall risk in older women.

Introduction: Novel technologies based on virtual reality (VR) are creating attractive virtual environments with high ecological value, used both in basic/clinical neuroscience and modern medical practice. The study aimed to evaluate the effects of VR-based training in an elderly population. Materials and methods: The study included 36 women over the age of 60, who were randomly divided into two groups subjected to balance-strength and balance-cognitive training. The research applied both conventional clinical tests, such as (a) the Timed Up and Go test, (b) the five-times sit-to-stand test, and (c) the posturographic exam with the Romberg test with eyes open and closed. Training in both groups was conducted for 10 sessions and embraced exercises on a bicycle ergometer and exercises using non-immersive VR created by the ActivLife platform. Machine learning methods with a k-nearest neighbors classifier, which are very effective and popular, were proposed to statistically evaluate the differences in training effects in the two groups. Results and conclusion: The study showed that training using VR brought beneficial improvement in clinical tests and changes in the pattern of posturographic trajectories were observed. An important finding of the research was a statistically significant reduction in the risk of falls in the study population. The use of virtual environments in exercise/training has great potential in promoting healthy aging and preventing balance loss and falls among seniors.

Effects of exercise training after acute coronary syndromes in octogenarians - prospective 12-month evaluation.

OBJECTIVE: Aim: To demonstrate the impact of individual exercise training on the course of the disease, exercise tolerance and quality of life (QoL) in patients over 75 years after acute coronary syndrome (ACS). PATIENTS AND METHODS: Materials and methods: Study included octogenarians after ACS randomly assigned into two groups: a training group (ExT) subjected to individualized physical training and a control group (CG) with standard recommendations for activity. Patients underwent exercise tolerance test (ETT), 6-minute walk test (6-MWT), NHP and QoL questionnaires evaluation, lab tests, ECG, echocardiographic examination at the beginning and after 2, 6 and 12 months. RESULTS: Results: Study included 51 patients, mean age 80 years, 50% men, all patients completed the study. Initial physical capacity was comparable in both groups. After 2-month training the average ETT exercise time increased by 12.5% (p=0.0004), the load increased by 13% (p=0.0005) and the 6-MWT results improved by 8.3% (p=0.0114). Among CG these changes were not significant. But 6 and 12 months after training cessation 6-MWT results returned to the initial values (p=0.069, p=0.062 respecitvely). Average ETT exercise time and average load decreased significantly after 12 months (p=0.0009, p=0.0006). Level of pain was significantly lower at the end of the training in ExT group (p=0.007), but it returned to initial 12 months later (p=0.48). QoL deteriorated significantly in the ExT group 12 months after training cessation (p=0.04). CONCLUSION: Conclusions: Cardiac rehabilitation in octogenarians after ACS was safe and improved physical performance in a short period of time. Cessation of training resulted in a loss of achieved effects and deterioration of the QoL.

Patient-Reported Quality of Life, Depression, Anxiety, and Physical Activity in Patients Receiving an Implantable Cardioverter-Defibrillator for Primary versus Secondary Prevention: A Single-Centre, Prospective, Observational Cohort Study.

STUDY OBJECTIVES: The aim of the study was to evaluate of the quality of life, depression, anxiety levels, and physical activity in the groups after the implantation of an ICD or CRT-D. METHODS: All subjects (111 CHF patients) underwent tests to assess the quality of life (NHP), the level of physical activity (IPAQ), the level of perceived stress (PSS), and the incidence of depression (BDI). RESULTS: After the implantation, physical activity (PA) of the patients from the primary prevention (PP) group remains unchanged, whereas in the secondary prevention (SP) group, it decreases noticeably. Physical activity is lower in the SP group in comparison with the PP group. There are no statistically significant differences in the level of depression. The scores in the second part of the NHP questionnaire indicate that the SP group significantly more often declare problems with housework and with social life than the PP group. CONCLUSIONS: 1. The type of prevention does not have an influence on the level of anxiety, stress, or depression. 2. The patients after implantation as SP are physically less active; lower PA is associated additionally with the higher NYHA class and chronic kidney disease. 3. The quality of life of the patients from SP group is at a lower level than patients from PP group.

Cluster Analysis to Distinguish Patients Most Likely to Benefit from Outpatient Cardiac Rehabilitation-A Prospective, Multicenter Study.

Offering cardiac rehabilitation to people who can benefit most could improve the outcomes in the context of limited availability. We used cluster analysis to distinguish three patient groups based on clinical and laboratory variables and then compared the outcomes of 6-month outpatient cardiac rehabilitation between these groups. The outcomes included blood pressure, blood lipids, fasting blood glucose, and uric acid concertation in serum. Group 1 consisted primarily of men with obesity, increased blood pressure, favourable lipid profiles and increased fasting glucose. Group 2 consisted of men or women with normal weight, normal blood pressure, favourable lipid profiles, and normal fasting glucose. Group 3 consisted primarily of women with overweight, normal blood pressure, unfavourable lipid profiles, and normal fasting glucose. After 6 months of cardiac rehabilitation, blood lipids improved in group 3, whereas blood pressure improved in groups 1 and 3, but the outcomes did not change significantly in group 2. We did not see any effect of cardiac rehabilitation on fasting blood glucose and serum uric acid concentration in any group. Concentrations of glucose and uric acid did not change significantly in any group. In conclusion, an adequate selection of patients should maximise the benefits of cardiac rehabilitation.

Comprehensive cardiac rehabilitation as the keystone in the secondary prevention of cardiovascular disease.

Comprehensive cardiac rehabilitation (CR) is a mainstay of the secondary prevention of cardiovascular disease. In the European Society of Cardiology guidelines, comprehensive cardiovascular rehabilitation has the highest class of recommendation and level of evidence as an effective method for the treatment of patients with ST-segment elevation myocardial infarction, after myocardial revascularization, with chronic coronary syndrome, for CVD prevention in clinical practice, and in patients with heart failure (HF). This document presents an expert opinion of the Cardiac Rehabilitation and Exercise Physiology Section of the Polish Cardiac Society concerning the definition, goals, target population, organization of rehabilitation services, standard clinical indications and methods of implementation. Moreover, it describes psychosocial risk factors influencing the course of CR and secondary prevention of cardiovascular disease in patients undergoing CR. Comprehensive CR is as a process that should be implemented as soon as possible, continued without interruption, and consist of multiple stages. Moreover, it should be tailored to the individual clinical situation and should be accepted by the patient and their family, friends, and caregivers.

No effects of cardiac resynchronization therapy and right ventricular pacing on the right ventricle in patients with heart failure and atrial fibrillation.

BACKGROUND: The right ventricle (RV) function is crucial in heart failure with reduced ejection fraction (HFrEF), especially in patients with atrial fibrillation (AF). Aims. To assess the RV structure and function in patients with HFrEF, permanent atrial fibrillation (AF), cardiac resynchronization therapy (CRT) and RV pacing (RVp) with two- and three-dimensional echocardiography. Methods. Patients with ischemic HFrEF (NYHA II-III; LVEF ≤40%) were enrolled. The studied groups were: sinus rhythm (SR, control); AF and no implanted devices - AF/0; AF and CRT - AF/CRT; AF and RVp - AF/RVp. Two- and three-dimensional echocardiographic parameters of RV structure and function were analyzed in study groups. Results. The study included a group of 126 patients: n = 32 with SR, n = 28 with AF/0, n = 25 with AF/CRT and n = 41 with AF/RVp. Results were worse in AF groups than in SR: right ventricular ejection fraction, %, mean (SD): SR - 48.2 (7.5), AF/0 - 36.5 (6.5), AF/CRT - 38.3 (7.6), AF/RVp - 37.1 (7.7), p < .001. Other parameters lower in AF groups than in SR were: RV end-systolic volume, longitudinal strain of the free wall and tricuspid lateral annular systolic velocity. There were no differences between groups with AF and CRT and RV pacing in other analyzed parameters between AF groups and SR. Conclusions. In heart failure with reduced left ventricular ejection fraction and atrial fibrillation right ventricular pacing and cardiac resynchronization therapy were not associated with modified right ventricular function. Further prospective studies are needed to evaluate prognostic significance of these results.

Exercise training program in patients with NYHA III class systolic heart failure - Parallel comparison to the effects of resynchronization therapy.

PURPOSE: The aim of this study was to assess exercise capacity and echocardiographic parameters in patients with heart failure with reduced ejection fraction (HFrEF) in NYHA III functional class, after cardiac resynchronization therapy (CRT) or implantable cardioverter-defibrillator (ICD) implantation followed by 6 months of supervised rehabilitation in ICD patients. MATERIALS AND METHODS: The study included patients with HFrEF and impaired left ventricle systolic function (LVEF ≤ 35%), divided into two groups: CRT group - patients after CRT-D implantation > six weeks, and ICD-rehab group - patients after ICD implantation > six weeks, followed by 6 months of supervised aerobic interval training and the conditioning exercises. At baseline and after 6 months in all the patients cardiopulmonary exercise tests (CPX) and standard echocardiographic examinations were performed. RESULTS: The study included 61 patients (49-77 years) with HFrEF. At baseline, the values of CPX parameters were similar in both groups. After completing training almost all CPX parameters in the ICD-rehab group significantly improved, except for anaerobic threshold (AT). In the CRT group significant improvements were found in 2 parameters: peak oxygen uptake (VO2) and exercise tolerance (metabolic equivalents, METs). Significant reductions in left and right ventricle diameters and an increase in LVEF were observed in both groups after 6 months. CONCLUSIONS: Significant improvement in exercise tolerance capacity and increase of LVEF were observed in similar extent both in heart failure patients with CRT and with ICD undergoing the rehabilitation program. Regular, controlled exercise trainings provided additional, safe and easy to conduct therapeutic option for heart failure patients with no indications for CRT.

Improvement of exercise tolerance in cardiopulmonary testing with sustained safety after regular training in outpatients with systolic heart failure (NYHA III) and an implantable cardioverter-defibrillator. Prospective 18-month randomized study.

INTRODUCTION: The aim of the study was to evaluate the impact of individual training on the level of physical capacity and echocardiographic parameters in patients with systolic heart failure (SHF), NYHA III and an implantable cardioverter-defibrillator (ICD). MATERIAL AND METHODS: The study included 84 patients with SHF, randomly assigned to one of two groups: with regular training (ICD-Ex) and a control group (ICD-control). The ICD-Ex group participated in a hospital rehabilitation program which after discharge was individually continued for 6 months in an outpatient setting. The ICD-control group participated in a training program during hospitalization, but after discharge did not perform any controlled activities. Prior to discharge, at 6 and 18 months cardiopulmonary exercise testing (CPX), standard echocardiographic examination and the 6-minute walk test (6-MWT) were performed in all patients. RESULTS: After 18 months in the ICD-Ex group most of the CPX parameters improved significantly (VO2 peak, ml/kg/min: 13.0 ±4.1 vs. 15.9 ±6.1, p < 0.0017; VCO2 peak, l/min: 1.14 ±0.34 vs. 1.58 ±0.65, p < 0.0008; Watt: 74.5 ±29.7 vs. 92.6 ±39.1, p < 0.0006; METs 3.72 ±1.81 vs. 4.35 ±1.46, p < 0.0131). In the ICD-control group no significant improvement of any parameter was observed. Left ventricular systolic dimensions remained significantly lower at 18 months only in the ICD-Ex group (49.5 ±11.0 vs. 43.4 ±10.0, p < 0.011). Left ventricular ejection fraction in both groups significantly increased at 6 and 18 months compared to baseline (ICD-Ex: 25.07 ±5.4 vs. 31.4 ±9.2, p < 0.001, vs. 30.9 ±8.9, p < 0.002, ICD-C: 25.1 ±8.3 vs. 29.2 ±7.7, p < 0.012 vs. 30.1 ±9.1, p < 0.005). Distance of the 6-MWT was significantly improved after 6 and 18 months in the ICD-Ex group and was overall longer than in the ICD-control group (491 ±127 vs. 423 ±114 m, p < 0.04). CONCLUSIONS: An individual, 6-month training program, properly controlled in patients with SHF and an implanted ICD, was safe and resulted in a significant improvement of exercise tolerance and capacity and echocardiographic parameters.

Hospital-based and telemonitoring guided home-based training programs: effects on exercise tolerance and quality of life in patients with heart failure (NYHA class III) and cardiac resynchronization therapy. A randomized, prospective observation.

UNLABELLED: Cardiac resynchronization therapy with defibrillator function (CRT-D) along with an optimal medical therapy improves symptoms, cardiac efficiency, quality of life (QoL) and prognosis in patients with heart failure (CHF). The aim of the study was to assess effects of hospital-based and home-based/telemonitoring exercise training. METHODS: The prospective, randomized study was conducted in 52 patients (pts), aged 45-75years (mean 62±9.3), with CHF of ischemic or another etiology, NYHA class III and implanted CRT-D. Group CRT-Ex (n=26) underwent initial exercise training in the hospital setting and continued training program at home with telemonitoring 5 times a week for 8weeks. The CRT-control group (n=26) consisted of patients who had hospital rehabilitation, but no training program after discharge. RESULTS: No differences between the groups in CHF etiology, comorbidities, medical therapy and in any of spiroergometry (CPX) parameters at baseline were observed. After 3-4months the CRT-Ex group achieved better results in VO2 peak, VCO2 peak and treadmill test duration. But after 12months the measurements returned to the baseline values. No significant differences were observed directly between two groups in distances of 6-MWT at baseline, at 3-4months and at 12months. Echocardiographic evaluation showed significant reduction of left ventricular dimensions and improvement in the left ventricular ejection fraction (EF), in both groups (25.3±7.4% to 28.9±9.1%, CRT-Ex group, p=0.0213 and 24.9±7.2% to 31.7±10.6%, CRT-Control group, p=0.0001). Significant improvement in all domains of QoL was observed in the CRT-Ex group, while the CRT-Control pts declared only higher energy levels and less pain. Intensity of telemonitoring guided home-based exercise training was low. In the 12- and 18-months follow-up there were no differences in the ICD-interventions, mortality or hospitalization rates between the groups. CONCLUSIONS: A structured exercise training program in the hospital and home-based with telemonitoring was safe option of additional treatment and improved directly physical fitness and, quality of life in patients with NYHA III CHF and CRT-D. However these effects haven't been sustained in longer period of time and had no impact on prognosis.

Prospective assessment of cytokine IL-15 activity in patients with refractory atrial fibrillation episodes.

AIMS: Inflammatory state is considered a risk factor of atrial fibrillation (AF) occurrence. The aim of this study was a prospective evaluation of the inflammation parameters in patients with different forms of AF without structural heart disease. METHODS AND RESULTS: One hundred fifty-eight patients with paroxysmal/persistent AF (87; 55.1% men, mean age 65.8±9.6 years) without structural heart disease were enrolled in the study. Inflammatory parameters: WBC, ESR, hs-CRP, IL-6, IL-15 and TNF-alpha were measured at baseline and after one year follow-up. Despite frequent AF episodes median values of WBC, ESR and C-reactive protein at baseline and after follow up were within normal ranges. There were no significant differences between WBC, ESR and hs-CRP regarding AF types. In patients who developed permanent AF form (n=14) hs-CRP concentrations were higher at baseline: 0.35 (IQR1: 0.09 IQR: 0.61) vs 0.15 (IQR1: 0.07 IQR: 0.29), p<0.01. Nevertheless, after one year's observation these differences were not significant. Among all cytokines were studied only IL-15 was significantly correlated with the number of AF episodes (r=0.26), mean (IQ1-IQ3): 10 (3-30) vs 60 (50-100), p=0.00681. CONCLUSION: Basic inflammatory markers were not changed in patients with refractory atrial fibrillation episodes in prospective one year's observation. Only cytokine IL-15 was correlated to numbers of AF episodes. It's potential role as a marker of arrhythmia deserves further evaluation.

Effectiveness of antitachycardia pacing therapy after primary prophylaxis implantation of implantable defibrillators in coronary artery disease patients.

PURPOSE: Effectiveness of implantable defibrillators (ICD) has been proven with large randomized trials. Unfortunately, ICD discharge is painful and potentially threatening for the patient despite its life saving effects. We analyzed influence of the clinical parameters present before implantation on the effectiveness of antitachycardia pacing therapy (ATP) in terminating ventricular tachycardia (VT) slower than 200 bpm in the coronary artery disease patients with prophylactic implanted ICD in a single centre retrospective trial. PATIENTS/METHODS: We analyzed 121 consecutive coronary disease patients with ICD implanted in primary prophylaxis between 2001 and 2007, with the mean age of 62 ± 10 years. The mean follow-up was 876 ± 538 days. RESULTS: 32 of them had VT. In 27 persons (84.4%) at least one ATP attempt terminate VT. ATP was always successful in 21 patients. We analyzed age, sex, LVEF, NYHA class, widening of QRS complex, atrial fibrillation, type of myocardial infarction or diabetes. There were no significant differences in clinical features between patients with successful and unsuccessful ATP therapy. CONCLUSIONS: High effectiveness of ATP was shown in this group. There were no clinical factors indicating success of this type of therapy. That could justify programming ATP as the first line therapy in the VT zone in primary prophylaxis coronary artery disease patients to reduce application of shock therapy. It should be possible to apply a single mode of programming when discharging patients after the implantation procedure regardless of the patient's clinical condition. This could help to control and programme the devices, thus reducing the risk of errors.

Beneficial triple-site cardiac resynchronization in a patient supported with an intra-aortic balloon pump for end-stage heart failure.

The authors present the case of a 62-year-old male patient with an implantable cardioverter-defibrillator and end-stage heart failure supported with an intra-aortic balloon pump. Implantation of a triple-site cardiac resynchronization system and complex heart failure treatment brought a significant improvement, return to home activity and 17-month survival. The patient died due to heart failure aggravation. Within this time he was rehospitalized and successfully treated twice for an electrical storm.

Potential prevention of pacing-induced heart failure using simple pacemaker programming algorithm.

INTRODUCTION: Right ventricular pacing (RVP) causes ventricular desynchronization and may lead to the development of heart failure (HF). Prolongation of atrioventricular delay (AVD) in DDDR pacemakers reduces unnecessary RV stimulation. The aim of the study was to verify the influence of RVP reduction on HF symptoms. METHODS: The study comprised 31 patients (17 men, mean age: 71.6 ± 8 yrs) with DDDR pacemaker implanted due to sinus node dysfunction (SND). At baseline, 28 patients did not present any symptoms of HF. Three patients were in NYHA class II. Patients were randomized either to 150 ms AVD or to minimizing right ventricular pacing (MRVP). Crossing over to the alternate mode took place after 4 months. Cardiopulmonary exercise test (CPX), echocardiography (ECHO) and BNP measurements were done before pacemaker implantation, after 4 and 8 months. RESULTS: The percentage of RVP was significantly higher in 150 ms AVD than in MRVP: 81.7 ± 22.6 versus 14.2±20.5%, P < 0.0001. Patients with 150 ms mode had worse CPX parameters than those with MRVP mode: peak oxygen uptake was 14.2±4.3 versus 19.9±6.3 ml/kg per min, P = 0.0001, higher BNP concentrations: 72.3±48.3 versus 49.4±43.9 pg/ml, P = 0.001 and worse left ventricle [LV] function: ejection fraction: 53.2±6.7 versus 57.3±5.5%, P < 0.0001; LV diastolic diameter: 4.86±0.52 versus 4.66±0.5 cm, P < 0.01. CONCLUSION: Predominant RVP in patients without symptoms of HF at baseline may be responsible for worse performance in cardiopulmonary exercise test, higher BNP concentrations and impairment of LV function. Specific DDDR pacemaker programming promotes intrinsic AV conduction and may prevent the development of pacing-induced HF.

Combined hypotensive treatment with ≥ 3 hypotensive drugs in patients with recurrent atrial fibrillation and arterial hypertension ensures more effective arrhythmia control than using less drugs.

BACKGROUND: Combined arterial hypertension (AH) therapy ensures the effectiveness of treatment and improves haemodynamic parameters of cardiac function. AIM: The evaluation of therapeutic regimens in the prevention of recurrence of atrial fibrillation (AF) episodes in hypertensive patients with paroxysmal/persistent forms of AF. METHODS: Prospective observation included patients (n = 164), without and with AH, grade I and II, with paroxysmal (51.3%) or persistent (48.7%) recurrent form of arrhythmia. Mean duration of AF was 4.0 years, (Q1:2; Q3:7). The anti-arrhythmic drugs were ineffective in prevention of AF episodes or non tolerated and were not used. In all patients precise control of blood pressure (BP) was implemented: patients were treated with beta-blockers: 100%; ACE-I: 65%, spironolactone: 47%, thiazide diuretics: 34%, loop-diuretics: 7%, calcium antagonists: 26.5% and alpha-blockers: 14.5%. Evaluation of symptomatic and confirmed AF episodes was performed every 3 months during 1-year follow-up. RESULTS: AH, grade I and II, was diagnosed in 115, 75%, of patients; (74% men, mean age 65.5 ± 9.7 years). Persistent form of arrhythmia was more frequent in patients with AH: 83% in comparison with patients without AH: 67% (p 〈 0.05). BP values were similar in normotensive and hypertensive patients after completing the study: 123 ± 9/79 ± 4 vs. 124 ± 10/80 ± 0.5 mm Hg. One hypotensive drug was used in 6 patients, 2 drugs in 38 patients, 3 in 37, 4 in 27, 5 in 7. Patients treated with . 3 drugs had more AF episodes in 3 months prior to evaluation: 4.7 ± 0.8 vs. 2.9 ± 0.4, p = 0.0444. But during 1-year follow-up, observed in 3-months periods, they had significant reduction in every 3-months period, p = 0.0001. Patients treated with 1.2 drugs had significant reduction after 3 months: p = 0.0029, 6 months: p = 0.04 and 12 months: p = 0.0012, but not after 9 months. CONCLUSIONS: AH promotes more advanced AF forms occurrence. Combined hypotensive therapy with minimum 3 drugs, including RAA inhibitors, may be effective in terms of BP control and reduction of arrhythmia episodes.

[Clinical improvement after physical training in patient with severe postinfarction heart failure, who underwent prosthetic heart valve implantation and numerous coronary interventional procedures]. / Kliniczna poprawa po treningu fizycznym u pacjenta z ciezka pozawalowa niewydolnoscia serca, po wszczepieniu sztucznej zastawki aortalnej i licznych interwencjach wiencowych.

The case of patient with advanced congestive heart failure, NYHA III, of ischaemic and valvular aetiology and concomitant diseases is presented. Introduction of 6-month, controlled physical training resulted in improvement of health status, exercise performance, ventilation and left ventricular function. Quality of life got significantly better. This aspect of treatment should be considered in majority of patients with heart failure.

Physical activity long-term after liver transplantation yields better quality of life.

BACKGROUND: Transplantation is the only effective method of treatment for end-stage and acute liver failure. Increased average survival time has been observed, and results from improved surgical technique and amended immunosuppression protocols. However, longer survival of patients after orthotopic liver transplantation (OLT) results in higher rate of various complications and ailments (eg, chronic fatigue, anxiousness, social isolation). Hence, gradual deterioration of health-related quality of life (HRQoL) is likely. The goal of this study was to examine the relation between physical activity and quality of life in patients 5 years after OLT. MATERIAL/METHODS: Twenty-six randomly selected patients who survived more than 5 years after orthotopic liver transplantation were included into the study. An SF-36 questionnaire was used for assessment of quality of life. Physical activity was measured subjectively by characterizing its type, duration and frequency per week during the previous 12 months. Patients were divided into 2 groups according to the results of physical activity assessment. Group A consisted of patients who had indicated they had a sedentary life style, and group B of those regularly engaging in physical exercise. RESULTS: Results of the SF-36 questionnaire in 10 categories were compared between the 2 groups. The majority of aspects of health-related quality of life (physical function, body problems, general health, social function, and emotional reaction) were significantly improved in patients who indicated they regularly engaged in physical exercise. CONCLUSIONS: Better quality of life was observed in patients who were physically active after OLT. Improving life quality with regular physical activity could be a valuable supplementation of complex management of OLT recipients.

Effect of combined spironolactone-ß-blocker ± enalapril treatment on occurrence of symptomatic atrial fibrillation episodes in patients with a history of paroxysmal atrial fibrillation (SPIR-AF study).

Angiotensin II and aldosterone are key factors responsible for the structural and neurohormonal remodeling of the atria and ventricles in patients with atrial fibrillation (AF). The aim of the present study was to evaluate the antiarrhythmic effects of spironolactone compared to angiotensin-converting enzyme inhibitors in patients with recurrent AF. A cohort of 164 consecutive patients (mean age 66 years, 87 men), with an average 4-year history of recurrent AF episodes, was enrolled in a prospective, randomized, 12-month trial with 4 treatment arms: group A, spironolactone, enalapril, and a ß blocker; group B, spironolactone and a ß blocker; group C, enalapril plus a ß blocker; and group D, a ß blocker alone. The primary end point of the trial was the presence of symptomatic AF episodes documented on the electrocardiogram. At 3-, 6-, 9-, and 12 months, a significant (p < 0.001) reduction had occurred in the incidence of AF episodes in both spironolactone-treated groups (group A, spironolactone, enalapril, and a ß blocker; and group B, spironolactone plus a ß blocker) compared to the incidence in patients treated with enalapril and a ß blocker (group C) or a ß blocker alone (group D). No significant difference was seen in AF recurrences between patients taking spironolactone and a ß blocker with (group A) and without (group B) enalapril. No significant differences were found in the systolic or diastolic blood pressure or heart rate among the groups before and after 1 year of follow-up. In conclusion, combined spironolactone plus ß-blocker treatment might be a simple and valuable option in preventing AF episodes in patients with normal left ventricular function and a history of refractory paroxysmal AF.

Quality of life and depression in patients with different patterns of atrial fibrillation.

BACKGROUND: atrial fibrillation (AF) is difficult to cure and significantly affects quality of life was well as emotional status of patients. AIM: to evaluate quality of life and depression level in patients with various patterns of AF. METHODS: we studied 150 consecutive patients with AF aged 35-83 years, including 61 patients with paroxysmal AF, 46 patients with persistent AF, and 43 patients with permanent AF. The control group included 70 healthy persons (mean age: 55.5 ± 14.5 years). Quality of life was estimated using the Nottingham Health Profile questionnaire. Risk of depression occurrence was estimated using the Beck Depression Inventory scale. Physical abilities, energy level, pain, emotional reactions, sleep, social isolation, problems with work, family life and sexual life were analysed. RESULTS: the mean age of patients with paroxysmal AF was higher in comparison to patients with permanent AF (68.4 ± 9.4 vs 62.0 ± 9.2 years, p < 0.05). In patients with all AF forms, the prevalence of symptoms indicating depression was significantly higher in comparison with control group (paroxysmal AF: 10.8 ± 5.8%, persistent AF: 10.0 ± 6.4%, permanent AF: 10.1 ± 7.2% vs 5.7 ± 5.8% in controls, p < 0.01). The level of depression was higher in women regardless of AF form (p < 0.005). Patients with paroxysmal and permanent AF had lower scores of emotional reactions (p < 0.05) and social isolation (p < 0.05) in comparison with the control group. All patients with AF had lower scores of energy level in comparison with the control group (paroxysmal AF: 1.2 ± 0.2, persistent AF: 1.1 ± 0.2, permanent AF: 1.2 ± 0.2 vs 0.5 ± 0.1 in controls, p < 0.005). Patients with paroxysmal, persistent and permanent AF had greater degree of activity limitations than the control group (1.8 ± 0.2, 1.7 ± 0.3, 2.1 ± 0.3, respectively, vs 1.0 ± 0.2, p < 0.005). Limitations of work were detected in 28.6-35.9% of patients with various forms of AF, sex life disturbances in 23.8-33.9% of patients, and family life problems in 10.3-21.4% of patients. The lowest results of these scores were noted in patients with paroxysmal AF. CONCLUSIONS: atrial fibrillation, independently of its form, has substantial impact on the risk of depression occurrence. Patients with paroxysmal and permanent AF had lower self-evaluation of their energy level. In all studied groups of AF patients, the arrhythmia significantly limited quality of life, especially sexual life as well as professional and home activity.
