Ventricular Arrhythmias in Left Ventricular Assist Device Patients-Current Diagnostic and Therapeutic Considerations.

Left ventricular assist devices (LVAD) are used in the treatment of advanced left ventricular heart failure. LVAD can serve as a bridge to orthotopic heart transplantation or as a destination therapy in cases where orthotopic heart transplantation is contraindicated. Ventricular arrhythmias are frequently observed in patients with LVAD. This problem is further compounded as a result of diagnostic difficulties arising from presently available electrocardiographic methods. Due to artifacts from LVAD-generated electromagnetic fields, it can be challenging to assess the origin of arrhythmias in standard ECG tracings. In this article, we will review and discuss common mechanisms, diagnostics methods, and therapeutic strategies for ventricular arrhythmia treatment, as well as numerous problems we face in LVAD implant patients.

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.

The Comparative Effectiveness and Safety of Different Anticoagulation Strategies for Treatment of Left Atrial Appendage Thrombus in the Setting of Chronic Anticoagulation for Atrial Fibrillation or Flutter.

PURPOSE: To compare effectiveness of different treatments for atrial fibrillation (AF) patients who were scheduled for cardioversion (CV) or ablation (CA) presenting with left atrium appendage (LAA) thrombus despite chronic oral anticoagulation therapy (OAC). METHODS: This was a retrospective cohort study. We analyzed 2014-2019 medical records of patients scheduled for CV or CA of AF who were diagnosed with LAA thrombus despite optimal OAC and had a follow-up transesophageal echocardiogram (TOE). Changes in treatment were divided into the following groups: switch to a drug with different mechanism of action, switch to a drug with similar mechanism of action, initiation of combination therapy, or deliberate no change in treatment. Patients with contraindications to non-vitamin K antagonists were excluded from the analysis. RESULTS: We analyzed data of 129 patients comprising 181 cycles of treatment. The overall effectiveness of LAA thrombus dissolution was 51.9% regardless of the number of cycles and 42.6% for the first cycle of treatment. Any change of treatment was more effective than deliberate no change-OR 2.97 [95% CI: 1.07-8.25], P = 0.031, but no particular strategy seemed to be more effective than the other. Left atrium area (OR 0.908 [95% CI: 0.842-0.979]) and number of treatment cycles (OR 0.457 [95% CI: 0.239-0.872]) were both adversely related to thrombus resolution. There was one ischemic and three bleeding adverse events during the treatment. CONCLUSION: LAA thrombus resolution in patients already on OAC may require a change of previous OAC treatment but the overall effectiveness of dissolution seems to be about 50%.

IMPACT OF EARLY EXERCISE-BASED CARDIAC REHABILITATION ON HOSTILITY, ITS BEHAVIORAL COMPONENTS AND DISEASE PERCEPTION IN PATIENTS AFTER MYOCARDIAL INFARCTION.

OBJECTIVE: Aim: Hostility and its behavioral components, anger and aggression are psychosocial risk factors for coronary heart disease. The purpose of the study was to evaluate the effectiveness of physical training on the level of negative emotions, the cognitive aspect of adaptation to disease and physical capacity in patients after MI who participated in cardiac rehabilitation. PATIENTS AND METHODS: Materials and Methods: We enrolled 60 post-MI men and women in the study. They underwent an 8-week training program. Before and after completion of trainings patients underwent exercise test and a psychological examination.The Buss-Perry Aggression Questionnaire and the Brief Illness Perception Questionnaire were performed with results analysis in the entire group and in subgroups of men, women, patients under 60 years of age (younger) and over 60 years of age (older). RESULTS: Results: After rehabilitation a significant reduction in the general level of negative emotions was found in younger: 67.8±4.6 vs 63.9±3.7 points (p< 0.01). Similarly, a significant reduction in the sense of the impact of the disease on life was found only in younger 6.96±0.5 vs 5.48±0.5 points (p<0.01). There was a significant improvement in overall adaptation to the disease in women from 40.6±2.2 to 35.7±1.9 points (p < 0.05).Moreover,patients with higher levels of negative emotions had more difficulty adapting to the disease r=0.361, p<0.01. Physical capacity increased significantly in all groups. CONCLUSION: Conclusions: Participating in cardiac rehabilitation improved physical capacity, beneficially contributed to a decrease in negative emotions and had a positive effect on disease adaptation but only in younger post -MI patients.

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.

Patterns of dyslipidemia in young patients with seronegative spondyloarthropathies without cardiovascular diseases.

OBJECTIVES: Patients with seronegative spondyloarthritis (SpA) - psoriatic arthritis (PsA) and ankylosing spondylitis (AS) - have a higher risk of cardiovascular morbidity and mortality. The aim of the present study was to evaluate the incidence and type of dyslipidemia, a potent atherosclerosis risk factor, in SpA patients. MATERIAL AND METHODS: It was a two-center, case-control study. Patients diagnosed with PsA and AS aged 23-60 years, with disease duration < 10 years, were enrolled. The inflammatory activity, serum levels of C-reactive protein (CRP) and lipid profile were evaluated in each patient. In patients > 40 years old, the 10-year risk of fatal cardiovascular disease (CVD), using Systematic Coronary Risk Evaluation (SCORE), was estimated. RESULTS: In total 79 patients with SpA were included in the study, with PsA diagnosed, n = 39 (mean age 45.1 ±9.6 years; 21, 53.9%, women), and with AS diagnosed, n = 40 (age 40.3 ±9.5; 12.3%, women), control group (CG): n = 88 (age 42.3 ±8.1; 42, 47.7% women). Based on the interview and laboratory tests, dyslipidemia was diagnosed in 19 (47.5%) patients with AS and in 28 (71.8%) patients with PsA. Most patients had hypercholesterolemia or mixed hyperlipidemia. Types of dyslipidemia were similar. In SpA patients (PsA and AS), the level of triglycerides (TG) and atherogenic index (AI) were significantly higher than in the CG, respectively TG in SpA: 116 (83-156) and in the CG: 91.2 (72.6-134.6) mg/dl, p = 0.0182; AI in SpA: 3.77 ±1.26 and in the CG: 2.58 ±1.27, p < 0.0001.The low-density cholesterol (LDL) level was significantly lower in SpA patients than in the CG, SpA: 109.1 ±29.4 vs. CG: 125.2 ±35.9 mg/dl, p = 0.0023. There was a strong negative correlation between CRP levels and HDL cholesterol levels in patients with PsA, rho = 0.42, p = 0.0132. Mean SCORE values were 2.33% in PsA patients and 2.38% in AS patients, which results in moderate 10-year risk of death from CVD. CONCLUSIONS: In young patients with spondyloarthropathies, inflammatory factors significantly influence dyslipidemia patterns, which result in higher TG and lower LDL cholesterol levels. In patients with PsA, dyslipidemia was diagnosed more often than in patients with AS.

Incremental prognostic value of echocardiography of left ventricular remodeling and diastolic function in STICH trial.

AIMS: We sought to determine which echocardiographic markers of left ventricular (LV) remodeling and diastolic dysfunction can contribute as incremental and independent prognostic information in addition to current clinical risk markers of ischemic LV systolic dysfunction in the Surgical Treatment for Ischemic Heart Failure (STICH) trial. METHODS AND RESULTS: The cohort consisted of 1511 of 2136 patients in STICH for whom baseline transmitral Doppler (E/A ratio) could be measured by an echocardiographic core laboratory blinded to treatment and outcomes, and prognostic value of echocardiographic variables was determined by a Cox regression model. E/A ratio was the most significant predictor of mortality amongst diastolic variables with lowest mortality for E/A closest 0.8, although mortality was consistently low for E/A 0.6 to 1.0. Mortality increased for E/A < 0.6 and > 1.0 up to approximately 2.3, beyond which there was no further increase in risk. Larger LV end-systolic volume index (LVESVI) and E/A < 0.6 and > 1.0 had incremental negative effects on mortality when added to a clinical multivariable model, where creatinine, LVESVI, age, and E/A ratio accounted for 74% of the prognostic information for predicting risk. LVESVI and E/A ratio were stronger predictors of prognosis than New York Heart Association functional class, anemia, diabetes, history of atrial fibrillation, and stroke. CONCLUSIONS: Echocardiographic markers of advanced LV remodeling and diastolic dysfunction added incremental prognostic value to current clinical risk markers. LVESVI and E/A ratio outperformed other markers and should be considered as standard in assessing risks in ischemic heart failure. E/A closest to 0.8 was the most optimal filling pattern.

Clinical factors affecting long term survival in patients with systolic heart failure and cardiac resynchronization therapy in advanced age.

Identification of demographic and clinical factors which influence prognosis is crucial in patients with heart failure and cardiac resynchronization therapy (CRT). MATERIALS AND METHODS: The study included 223 patients with CRT (177 males), mean age 64.6±9.7 years, including 98 patients (43.9%) with defibrillation function (CRT-D) and 58 (26.0%) with permanent atrial fibrillation (AF). Of 223, n=72 patients (32.3%) had CRT implanted after the age of 70. The mean follow-up was 37±19 months. Mortality rates and other clinical factors according to age were assessed in multivariable analysis of CRT patients follow-up. RESULTS: Total mortality was 30.9%. Mortality rate was similar in subjects aged ≤70 and >70 (HR:1.41, 95%CI:0.70-2.82). The female gender was the strongest clinical factor of best prognosis (HR:0.12,95%CI:0.03-0.59, p=0.0088). Lower mortality was also associated with higher left ventricular ejection fraction (HR:0.94,95%CI:0.90-0.98, p=0.0031). Coronary disease (HR:2.09,95%CI:1.10-3.99, p=0.0245), chronic kidney disease (HR:3.00, 95%CI:1.47-6.12, p=0.0024)and higher NYHA class (HR:2.28, 95%CI:1.18-4.40, p=0.0137) were factors of increased mortality. For patients >70 years old, gender was not a survival determining factor and mortality was lower in regard to hypertension or permanent AF. Only chronic kidney disease was significantly associated with higher mortality in patients >70 years old (HR:6.74, 95%CI:1.90-23.9). The use of defibrillation function had no influence on survival rate at any age. CONCLUSIONS: In patients with cardiac resynchronization therapy female gender was not associated with mortality and was the factor of better prognosis. For subjects aged >70 a worse prognosis was related to renal insufficiency.

Efficacy and safety of antazoline in the rapid cardioversion of paroxysmal atrial fibrillation (the AnPAF Study).

AIMS: The aim of the study was to assess the clinical efficacy of antazoline, a first-generation anti-histaminic agent, in the rapid conversion of paroxysmal non-valvular atrial fibrillation (AF) to sinus rhythm in patients without heart failure. METHODS AND RESULTS: This study was a single center, randomized, double blind, placebo-controlled, superiority clinical trial. We enrolled patients with an AF episode lasting less than 43 h, in stable cardiopulmonary condition. Subjects who fulfilled the selection criteria were randomly assigned to receive intravenously either a placebo or up to 250 mg of antazoline. The primary end point was the conversion of AF to sinus rhythm confirmed in electrocardiogram (ECG). We enrolled 74 patients: 36 (48.6%) in the antazoline group and 38 (51.4%) in the control group. The mean age was 68 ± 12 years (range 31-90 years), 39 (53.3%) patients were male. The successful conversion of AF to sinus rhythm during the observation period was achieved in 26 (72.2%) patients treated with antazoline and 4 (10.5%) in the control group: RR 6.86 (95% CI: 2.66-17.72, P < 0.0001). Median time to conversion was 16.0 min in antazoline and 72.5 min in the control group (P = 0.0246). There were no cases of atrial tachycardia/flutter in the antazoline group. CONCLUSION: Intravenous antazoline was effective and safe in the rapid conversion of non-valvular paroxysmal atrial fibrillation to sinus rhythm in patients without heart failure. Clinical Trial Registration number: NCT01527279.

Stable coronary artery disease - medical treatment.

The crucial issues in optimal medical therapy to improve prognosis and reduce angina symptoms are secondary prevention, effective control of concomitant diseases, risk factors and medical treatment. In spite of successful percutaneous coronary interventions (PCI) and medical treatment with beta-blockers, ACE-inhibitors or angiotensin receptor blockers, statins and antiplatelet drugs, some patients are still symptomatic. In the era of PCI not sufficient attention is paid to other drugs reducing the incidence of angina episodes: calcium antagonists, long-acting nitrates, metabolic agents and novel antianginal drugs. Substantial part of secondary coronary interventions may be avoided if angina pectoris would be properly treated. In the light of the Courage and BARI trials' results, optimal medical therapy of angina pectoris remains important part of treatment.

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.

Diet and Lifestyle Intervention-Induced Pattern of Weight Loss Related to Reduction in Low-Attenuation Coronary Plaque Burden.

BACKGROUND: Despite extensive research on body weight and cardiovascular risk, the mechanistic relationship between weight loss and coronary plaque modification has not been adequately addressed. This study aimed to determine the association between body composition dynamics and low-attenuation coronary plaque (LAP) burden. METHODS: Eighty-nine participants (40% women, 60 ± 7.7 years) of the Dietary Intervention to Stop Coronary Atherosclerosis in Computed Tomography (DISCO-CT) study with non-obstructive atherosclerosis with nonobstructive atherosclerosis confirmed in computed tomography angiography (CCTA), a randomized (1:1), prospective, single-center study were included into the analysis. Patients were randomly assigned to either experimental arm (intensive diet and lifestyle intervention atop optimal medical therapy, n = 45) or control arm (optimal medical therapy alone, n = 44) over 66.8 ± 13.7 weeks. Changes (∆) in body mass (BM) and body composition parameters, including total body fat (TBF), skeletal muscle mass (SMM), and fat-to-muscle ratio (FMR), measured with bioimpedance analyzer were compared with CCTA-measured ∆LAP. Coronary plaque analysis was performed using the 2 × 192 dual-energy scanner (Somatom Force, Siemens, Germany), while quantitative coronary plaque measurements were performed using a semi-automated plaque analysis software system (QAngioCT v3.1.3.13, Medis Medical Imaging Systems, Leiden, The Netherlands). RESULTS: Significant intergroup differences were found for ∆BM (-3.6 ± 4.9 kg in the experimental vs. -1.4 ± 2.9 kg in the control group, p = 0.015), ∆TBF (-3.4 ± 4.8% in the experimental vs. 1.1 ± 5.5% in the control arm, p < 0.001), ∆SMM (1.9 ± 2.8% in the experimental vs. -0.7 ± 3.2% in the control arm, p < 0.001), and FMR [-12.9 (-21.2; -4.3)% in the experimental vs. 3.1 (-5.3; 10.7)% in the control arm, p < 0.001]. ∆LAP did not differ significantly between the study arms; however, in the whole study population, ∆LAP was positively correlated with ∆BM, ∆TBF, and ∆FMR (r = 0.45, p < 0.001; r = 0.300, p = 0.004; r = 0.233, p = 0.028, respectively), and negatively with ∆SMM (r = -0.285, p = 0.007). Multivariate linear regression analysis revealed the association of ∆LAP with ∆BM, ∆TBF, and ∆FMR. CONCLUSIONS: The study intervention resulted in BM reduction characterized by fat loss, skeletal muscle gain, and increased FMR. This weight loss pattern may lead to a reduction in high-risk coronary plaque. Compared to a simple weight control, tracking body composition changes over time can provide valuable information on adverse coronary plaque modification.

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.

Treatment of insomnia in older adults. Recommendations of the Polish Sleep Research Society, Polish Society of Family Medicine and the Polish Psychiatric Association. / Leczenie bezsennosci osób w starszym wieku. Zalecenia Polskiego Towarzystwa Badan nad Snem, Polskiego Towarzystwa Medycyny Rodzinnej i Polskiego Towarzystwa Psychiatrycznego.

Insomnia is one of the most common health problems in developed countries. Its prevalence increases with age, with up to one in two people over the age of 65 experiencing symptoms of insomnia. The older people are also the patients who mostly commonly are among chronic sleep medication users. The aim of this article is to present the current recommendations for the management of insomnia in people over 65 years of age. The recommendations were prepared as a position of an expert panel, which included people from a number of clinical disciplines: family medicine, cardiology, psychiatry, sleep medicine and clinical psychopharmacology. The first step in treating sleep disorders is to establish proper diagnosis and, if possible, to initiate causal treatment. Moreover, cognitive and behavioural therapy for insomnia should also be used as the primary form of treatment, which can be supplemented, if not sufficiently effective, with pharmacological treatment. The main group of drugs used for treating insomnia are nonbenzodiazepine sedative hypnotics (zolpidem, zopiclone, eszopiclone, zaleplon). However, these drugs do not fully meet the needs of people over 65 years of age, primarily with regard to treatment safety. Therefore other classes of medicines, which are used for treatment of mental disorders, are prescribed off-label in this group of patients. Melatonin in a prolonged-release form is also indicated for this age group due to the high safety of the therapy. The management of insomnia in people over 65 years of age is a challenging task, given the need to seek compromise between treatment efficacy and safety. The treatment plan also has to take into account comorbidities as well as drugs used to treat them.

Short- and long-term survival of patients hospitalized for COVID-19 in relation to cardiovascular risk factors and established cardiovascular disease: the Cor-Cardio study.

INTRODUCTION: The clinical presentation of COVID­19 may range from asymptomatic infection to severe disease. Previous studies reported a relationship between the course of COVID­19 and a history of cardiovascular (CV) disease (CVD). OBJECTIVES: We aimed to analyze the influence of CV risk factors, established CVD, and treatment with CV drugs on short- and long­term survival in patients hospitalized for COVID­19. PATIENTS AND METHODS: We retrospectively analyzed data of patients hospitalized in 13 COVID­19 hospitals in Poland (between March and October 2020). Individual deaths during the follow­up were recorded until March 2021. RESULTS: Overall, 2346 patients with COVID­19 were included (mean age, 61 years; 50.2% women). A total of 341 patients (14.5%) died during the hospitalization, and 95 (4.7%) died during the follow­up. Independent predictors of in­hospital death were older age, a history of established CVD, heart failure, and chronic kidney disease (CKD), while treatment with renin­angiotensin­aldosterone system blockers or statins was associated with a lower risk of death during hospitalization. Factors that independently predicted death during the follow­up were older age, a history of established CVD, CKD, and a history of cancer. The presence of CV risk factors did not increase the odds of death either in the hospital or during the follow­up. Of note, higher systolic blood pressure and oxygen blood saturation on admission were associated with better short- and long­term prognosis. CONCLUSION: Established CVD and CKD were the main predictors of mortality during both the hospitalization and the follow­up in the patients hospitalized for COVID­19, while the use of CV drugs during the hospitalization was associated with better prognosis. The presence of CV risk factors did not increase the odds of in­hospital and postdischarge death.

Multimorbid management in atrial fibrillation: The Polish perspective in the EHRA-PATHS study.

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia and places a significant burden on individuals as well as the healthcare system. AF management requires a multidisciplinary approach in which tackling comorbidities is an important aspect. AIMS: To evaluate how multimorbidity is currently assessed and managed and to determine if interdisciplinary care is undertaken. METHODS: A 21-item online survey was undertaken over four weeks as part of the EHRA-PATHS study examining comorbidities in Atrial Fibrillation and distributed to European Heart Rhythm Association members in Europe. RESULTS: A total of 341 eligible responses were received of which 35 (10%) were from Polish physicians. Compared to other European locations, the rates of specialist services and referrals varied but were not significantly different. However, there were higher numbers of specialised services reported in Poland compared to the rest of Europe for hypertension (57% vs. 37%; P = 0.02) and palpitations/arrhythmias (63% vs. 41%; P = 0.01) and the rates of sleep apnea services tended to be lower (20% vs. 34%; P = 0.10) and comprehensive geriatric care (14% vs. 36%; P = 0.01). The only statistical difference between Poland and the rest of Europe in reasons for referral rates was the barrier relating to insurance and financial reasons (31% vs. 11%; P <0.01, respectively). CONCLUSIONS: There is a clear need for an integrated approach to patients with AF and associated comorbidities. Prepardeness of Polish physicians to deliver such care seems to be similar to other European countries but may be hampered by financial obstacles.

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.

Factors Affecting Early Mortality and 1-Year Outcomes in Young Women With ST-Segment-Elevation Myocardial Infarction Aged Less Than or Equal to 45 Years.

Given that up to 2% of patients with myocardial infarction (MI) are young women, the purpose of this study was to evaluate factors affecting outcomes in young women with ST-segment-elevation myocardial infarction (STEMI) aged less than or equal to 45 years. We evaluated 796 women with STEMI aged less than or equal to 45 years between 2007 and 2014, and mortality was 4.0%. Death occurred more often in women with prehospital sudden cardiac arrest, and severe symptoms of heart failure; less commonly, the women were subjected to percutaneous coronary intervention (PCI), with a higher rate of incomplete revascularization. Beta blockers (BB) and angiotensin converting enzyme inhibitors were frequently used in the survivor group. The independent predictor of 30-day mortality was as follows: inability to undergo PCI (odds ratio [OR] 4.6, 95% confidence interval [CI] 1.45-14.76, P = 0.009), sudden cardiac arrest (OR 4.5, 95% CI 1.5-18.3, P = 0.04). An increase in systolic blood pressure for every 5 mm Hg was associated with lower mortality, OR 0.90, 95% CI 0.76-0.97 in patients without cardiogenic shock (CS) and OR 0.69, 95% CI 0.61-0.78, P < 0.0001 in the group with CS. Predictors for 1-year mortality were the inability to undergo PCI (hazard ratio [HR] 84, 95% CI 1.6-43.1, P = 0.01) and CS (HR 6.97, 95% CI 1.39-34.7, P = 0.01). An increase of 5% in left ventricular ejection fraction reduced the mortality rate for 60% (HR 0.40, 95% CI 0.26-0.63, P < 0.0001) and an increase in systolic blood pressure for every 5 mm Hg reduced mortality for 34% (HR 0.66, 95% CI 0.52-0.84, P = 0.02). Both short- and long-term outcomes in young women aged less than or equal to 45 years with STEMI are good. The strongest predictor for both 30-day and 1-year mortality was the inability to undergo PCI. Suboptimal use of beta blockers and angiotensin converting enzyme inhibitors affect the outcomes in young women. Hypotension in the acute phase of MI increased mortality in young women, independent of coexisting CS.

Differences in Symptomatology and Clinical Course of Acute Coronary Syndromes in Women ≤45 Years of Age Compared to Older Women.

Acute coronary syndromes (ACS) in young people are rare. The data regarding differences in symptoms in relation to age are scarce, which may have an influence on outcomes. The aim of this study was to evaluate the differences in the clinical course of ACS between younger women (≤45 years old) and older women (63-64 years old). We compared 7481 women with ACS from the Polish Registry of ACS between 2007 and 2014 (1834 women aged ≤45 years and 5647 women aged 63-64 years). The predominant symptom of ACS in both groups was chest pain, with a higher incidence occurring in younger women (90.4% vs 88.5%, P = 0.025). Prehospital cardiac arrest occurred more often in younger women (2.1% vs 0.8%, P < 0.001), and onset-to-balloon time was shorter (8.9 vs 15.2 hours, P < 0.0001) in this group. Younger women presented with a lower Killip class at admission (class I at admission: 92.7% vs 86.2%, P < 0.001). The dominant type of ACS in the younger cohort was ST-segment elevation myocardial infarction (STEMI) (42% vs 26.1%), localized mainly in the anterior wall (47.7% vs 36.1%, P < 0.001), with a higher percentage of total occlusion of infarct-related artery (TIMI 0, 45.2% vs 36.1%) and left anterior descending artery engagement for all (33.5% vs 26.5%, P < 0.001). Drug-eluting stents were often used in the younger patients (43.3% vs 38.2%, P = 0.003) without significant differences in percutaneous coronary intervention numbers. Pharmacotherapy was used less in younger women. The 30-day and 2-year mortality in young women was lower than in the older cohort. The clinical course of ACS in younger women differed in comparison to older women. Younger women had a higher occurrence of typical chest pain, STEMI, and left anterior descending artery engagement. Except STEMI patients young women received faster revascularization, however with no significant differences in invasive treatment. Pharmacotherapy was inadequate in younger women and that resulted in a lower usage of the beta-blockers, angiotensin-converting enzyme inhibitors, and statins in that group. Short- and long-term mortality was low, regardless of the type of ACS.
