Background: Atrial cardiomyopathy (AtCM) encompasses patients with diverse demographics and comorbidities. This study aimed to identify phenotype groups with similar clinical characteristics, compare their mortality and atrial fibrillation (AF) event rates, and assess predictors of mortality. Methods and Results: We performed a hierarchical cluster...
Background: Managing acute decompensated heart failure (ADHF) is complex, particularly when combined with comorbidities like sleep apnea. Effective treatment requires personalized approaches, focusing on quality of life (QoL) and mental health outcomes. Purpose: This study explored the prevalence and characteristics of sleep apnea in patients with...
In a world where metabolic disorders such as non-alcoholic fatty liver disease (NAFLD/NASH) and chronic heart failure (CHF) steadily increase, the limitations of current therapies become even more apparent. Lifestyle changes have been the primary approach to metabolic disorders. However, the new use of glucagon-like peptide-1 receptor agonists (GLP...
Introduction: Atrial fi brillation is the main etiological factor leading to the development of atrial cardiomyopathy (ACM). The different types of atrial fi brillation (AF) are characterized by varying severity of atrial dysfunction, symptoms, and prognosis. Objective: The aim of our study is to analyze the echocardiographic parameters of patients w...
Background: Acute decompensated heart failure (ADHF) is often associated with central sleep apnea (CSA), which exacerbates cardiovascular strain and impacts quality of life. In ADHF patients, CSA contributes to recurrent nocturnal oxygen desaturation, elevated apnea-hypopnea index (AHI), and frequent Cheyne-Stokes respiration episodes, increasing h...
Background: Arterial hypertension is the most common factor for structural and functional changes in the heart, but these changes are observed in more advanced stages and in patients with poor control of arterial hypertension. Echocardiography plays a key role in detecting these changes, but a more detailed assessment is needed to identify early ch...
The individual approach in the treatment of heart failure (HF) and personalized medicine have been the main topic in recent years in all scientific forums. The combination of chronic obstructive pulmonary disease (COPD) and sleep apnea (SA) further complicates the clinical presentation in patients with HF. The overlap of all three diseases requires...
Introduction: Patients with diverse demographic and clinical characteristics and comorbidities are included in the category of atrial cardiomyopathy (ACM).
Aim: Our study aims to evaluate the demographic, clinical, laboratory, and echocardiographic parameters of patients with ACM and to assess their impact on prognosis.
Materials and methods: Only...
Background: Acute decompensated heart failure (ADHF) is a condition with a high frequency of hospitalizations and mortality, and obstructive sleep apnea (OSA) is a common comorbidity. Continuous positive airway pressure (CPAP) therapy at home can be a good adjunctive non-drug therapy for these patients. Methods: We conducted a single-center, prospe...
Background: Congenital absence of pericardium is a rare cardiac disorder with a reported incidence of less than 1 in 10,000. Although most of the cases are of little clinical significance, some of them are associated with serious complications, including risk of herniation and strangulation or coronary artery compression. Detailed Case Description:...
Background
Exacerbated heart failure is a condition with a high frequency of hospitalizations and mortality, especially in overweight patients. Screening and treatment for sleep apnea can be helpful in these patients.
Purpose
To determine the frequency and the phenotypic characteristics and of sleep apnea in patients with overweight and exacerbate...
Background
The main factor responsible for atrial cardiomyopathy (ACM) is atrial fibrillation (AF). It is known that AF causes remodeling of the left atrium but its effects on the right heart chambers and mortality are not well studied.
Purpose
To assess the echocardiographic characteristics of patients with atrial cardiomyopathy with long-standin...

Background
Often accompanying comorbidity in patients with acute heart failure and overweight is sleep disorders. Searching and treatment of sleep apnea will be helpful in these patients. CPAP therapy may improve the prognosis....
Sleep disorders are a common concomitant comorbidity in patients with heart failure. The aims of our study are to determine the incidence and phenotypic characteristics of sleep apnea in overweight patients with exacerbated heart failure and to assess the degree of involvement of systolic and diastolic function impairment in the individual group. F...
Background
Sabizabulin is an oral, novel microtubule disruptor with dual antiviral and anti-inflammatory activities. A randomized, multicenter placebo-controlled Phase 3 clinical trial was conducted in hospitalized moderate-severe COVID-19 patients at high-risk for acute respiratory distress syndrome (ARDS) and death. Patients were randomized (2:1)...
Heart failure is often accompanied by sleep disorders. CPAP therapy has proven in the treatment of obstructive sleep apnea, but the benefits associated with comorbid patients and patients with heart failure is still under research. On the other hand, central sleep apnea is also with high frequency in these patients and more difficult to treat. The...
Along with the development of evidence based medicine, the so-called „Medicine in cooperation
with the patient” has emerged recently due to the need to satisfy not only the medical needs of the
patients but also their psychological needs. A convenient approach to monitoring these requirements of
patients is the QoL. The purpose of the present study...
Cardiovascular diseases (CVDs) are a major factor in disabling the human population and they
are associated with signiÞ cant decrease in the quality of life (QoL) in these patients. The aim of the study
was to assess the QoL of patients with CVDs and to analyze the aspects that can be improved. The
subjects of this cross-sectional study were 215...
In the analysis of the quality of life (QoL) in patients with cardiovascular disease (CVD), different
approaches can be applied. The subjective approach involves perceiving, understanding and assessing
the impact of the disease on a patient basis due to the fact that objective factors are subjectively interpreted
by the patient with chronic dise...
