Aims: Heart failure (HF) is frequently accompanied by atrial fibrillation (AF), a combination that worsens the outcomes of both diseases. Despite advances in the treatment of AF, it remains a serious and unsolved problem for clinicians and researchers. The aim of this study was to examine risk factors for incidents of paroxysmal and persistent AF in patients having heart failure with mid-range ejection fraction (HFmrEF). Methods. Overall, 71 patients with HFmrEF and non-valvular AF, including paroxysmal and persistent types, were enrolled in this study. As a control group, 42 HFmrEF patients without AF were also enrolled. All patients underwent detailed physical examination, including resting electrocardiography, echocardiography, and 24-hour ambulatory Holter monitoring. Levels of the inflammation markers high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α) and the fibrotic marker transforming growth factor-β1 (TGF-β1) were measured by ELISA and expressed as odds ratios. Results: We show that paroxysmal AF was associated with higher diastolic blood pressure, whereas both paroxysmal and persistent forms of AF were associated with more frequent occurrence of hypertensive crisis episodes and greater body mass index. Progression from paroxysmal to persistent AF was associated with significant ventricular remodeling. Persistent and paroxysmal AF were associated with higher levels of inflammatory markers when compared to HFmrEF patients having no AF. In addition, TGF-1 was significantly increased in HFmrEF patients having persistent but not paroxysmal AF. Conclusions: Occurrence of AF, first paroxysmal and then persistent, in HFmrEF patients is associated with left ventricular remodeling and the appearance of systemic inflammatory and fibrotic markers. Changes in those parameters may be indicators by which to identify patients at increased risk of atrial fibrillation. Further studies are needed to determine the prognostic validity of these markers.

Heart failure (HF) and atrial fibrillation (AF) are the most common cardiovascular conditions in clinical practice and frequently coexist. The number of patients with HF and AF is increasing every year.Aim. To analyze the effect of clinical course and management of HF and AF on the outcomes.Material and methods. The data of 1,003 patients from the first Russian register of patients with HF and AF (RIF-CHF) were analyzed. The endpoints included hospitalization due to decompensated HF, cardiovascular mortality, thromboembolic events, and major bleeding. Predictors of unfavorable outcomes were analyzed separately for patients with HF with preserved ejection fraction (AF+HFpEF), mid-range ejection fraction (AF+HFmrEF), and reduced ejection fraction (AF+HFrEF).Results. Among all patients with HF, 39% had HFpEF, 15% — HFmrEF, and 46% — HFrEF. A total of 57,2% of patients were rehospitalized due to decompensated HF within one year. Hospitalization risk was the highest for HFmrEF patients (66%, p=0,017). Reduced ejection fraction was associated with the increased risk of cardiovascular mortality (15,5% vs 5,4% in other groups, p<0,001) but not ischemic stroke (2,4% vs 3%, p=0,776). Patients with HFpEF had lower risk to achieve the composite endpoint (stroke+MI+cardiovascular death) as compared to patients with HFmrEF and HFrEF (12,7% vs 22% and 25,5%, p<0,001). Regression logistic analysis revealed that factors such as demographic characteristics, disease severity, and selected therapy had different effects on the risk of unfavorable outcomes depending on ejection fraction group.Conclusion. Each group of patients with different ejection fractions is characterized by its own pattern of factors associated with unfavorable outcomes. The demographic and clinical characteristics of patients with mid-range ejection fraction demonstrate that these patients need to be studied as a separate cohort.

ObjectiveAssociations between atrial fibrillation (AF) and heart failure (HF) have been established. We compared the extent to which AF is associated with each primary subtype of HF, with reduced (HFrEF) versus preserved ejection fraction (HFpEF).MethodsWe included 25 787 participants free of baseline HF from the REGARDS (REasons for Geographic And Racial Differences in Stroke) cohort. Baseline AF was ascertained from ECG and self-reported history of physician diagnosis. Incident HF events were determined from physician-adjudicated review of hospitalisation medical records and HF deaths. Based on left ventricular ejection fraction (LVEF) at the time of HF event, HFrEF, HFpEF, and mid-range HF were defined as LVEF <40%, ≥50% and 40%–49%, respectively. Multivariable Cox proportional-hazards models examined the association between AF and HF. The Lunn-McNeil method was used to compare associations of AF with incident HFrEF versus HFpEF.ResultsOver a median of 9 years of follow-up, 1109 HF events occurred (356 HFpEF, 388 HFrEF, 77 mid-range and 288 unclassified). In a model adjusted for sociodemographics, cardiovascular risk factors, and incident coronary heart disease, AF was associated with increased risk of all HF events (HR 1.67, 95% CI 1.38 to 2.01). The associations of AF with HFrEF versus HFpEF events did not differ significantly (HR 1.87 (95% CI 1.38 to 2.54) and HR 1.65 (95% CI 1.20 to 2.28), respectively; p value for difference=0.581). These associations were consistent in sex and race subgroups.ConclusionsAF is associated with both HFrEF and HFpEF events, with no significant difference in the strength of association among these subtypes.

Abstract BackgroundIn previous studies, faster heart rates in patients with atrial fibrillation combined with heart failure have been associated with poor long-term patient prognosis. However, the classical pharmacological regimen of beta-blockers has not reduced mortality in patients with atrial fibrillation combined with heart failure. Therefore, in patients with atrial fibrillation combined with heart failure with an ejection fraction >40%, we further screened patients with a diagnosis of atrial fibrillation cardiomyopathy and compared the combination of diltiazem with standard anti-heart failure drug therapy.Objective:To observe the effect of diltiazem hydrochloride on cardiac function and prognosis in patients with Atrial Fibrillation–Mediated Cardiomyopathy.Methods: A total of 186 patients diagnosed with atrial fibrillation–mediated cardiomyopathy who were admitted to the First Affiliated Hospital of Zhengzhou University from August 2018 to June 2020 were randomly divided into two groups: 93 cases in the experimental group and 93 cases in the control group, both groups were given standardized pharmacological treatment for heart failure (diuretics, digoxin, β-blockers, perindopril), and the experimental group was given diltiazem 30 mg on the basis of standardized treatment, 3 times a day. The patients were followed up for 30 days to observe the target heart rate <110 beats/min, left ventricular ejection fraction, proBNP, the rate of decrease in activity tolerance during the treatment period, and readmission rate within 30 days.Results:After the addition of diltiazem, the attainment rate of target heart rate was significantly higher in the experimental group than in the control group (p<0.05) . The improvement of left ventricular ejection fraction and proBNP was more significant in the experimental group than in the control group (p<0.05). The incidence of decreased activity tolerance during the follow-up period was higher in the experimental group than in the control group, but the difference was not statistically significant (p>0.05). The readmission rate for heart failure within 30 days was significantly lower in the experimental group than in the control group (p < 0.05).Conclusion：Diltiazem hydrochloride is effective in improving cardiac function and prognosis in patients with atrial fibrillation–mediated cardiomyopathy, and is a safe and effective method.

Few Data

Oxidative stress (OS) is increased in chronic diseases, including cardiovascular (CV), but there are few data on its effects on the heart and vessels. The isoprostanes (IsoP) are bioactive compounds, with 8-iso-PGF25a being the most representative in vivo marker of OS. They correlate with the severity of heart failure (HF), but because data regarding OS levels in different types of HF are scarce, our study was aimed to evaluate it by assessing the urinary levels of 8-iso-PGF2aand its correlations with various biomarkers and parameters. Our prospective study included 53 consecutive patients with HF secondary to ischemic heart disease or dilative cardiomyopathy, divided according to the type of HF (acute, chronic decompensated or chronic compensated HF). The control group included 13 hypertensive patients, effectively treated. They underwent clinical, laboratory - serum NT-proBNP, creatinine, uric acid, lipids, C reactive protein (CRP) and urinary 8-iso-PGF2a and echocardiographic assessment. HF patients, regardless the type of HF, had higher 8-iso-PGF2a than controls (267.32pg/�mol vs. 19.82pg/�mol, p[0.001). The IsoP level was directly correlated with ejection fraction (EF) (r=-0.31, p=0.01) and NT-proBNP level (r=0.29, p=0.019). The relative wall thickness (RWT) was negatively correlated with IsoP (r=-0.55, p[0.001). Also 8-iso-PGF25a was higher by 213.59pg/�mol in the eccentric left ventricular (LV) hypertrophy subgroup comparing with the concentric subgroup (p=0.014), and the subgroups with severe mitral regurgitation (MR) and moderate/severe pulmonary hypertension (PAH) had the highest 8-iso-PGF2a levels. Male sex, severe MR, moderate/severe PAH, high LV mass and low RWT values were predictive for high OS level in HF patients.Eccentric cardiac remodeling, MR severity and PAH severity are independent predictors of OS in HF patients.

Lv Diastolic Dysfunction

Heart Failure with preserved Ejection Fraction (HFpEF) is a clinical syndrome in which patients have symptoms of Heart Failure (HF), such as dyspnea and fatigue, a Left Ventricular Ejection Fraction (LVEF) ≥ 50% and evidence of cardiac dysfunction as a cause of symptoms, such as abnormal Left Ventricular (LV) diastolic dysfunction with elevated filling pressures. Besides LV diastolic dysfunction, recent investigations suggest a more complex and heterogeneous pathophysiology, including systolic reserve abnormalities, chronotropic incompetence, stiffening of ventricular tissue, atrial dysfunction, secondary Pulmonary Arterial Hypertension (PAH), impaired vasodilatation and endothelial dysfunction. Unlike Heart Failure with Reduced Ejection Fraction (HFrEF), clinical trials over the years have not yet identified effective treatments that reduce mortality in patients with HFpEF. A database on use of carvedilol in a private cardiologist's practice was begun in 1997 and concluded at the end of 2018. We used this database to test the hypothesis that combining pharmacological interventions to address diastolic dysfunction (carvedilol), volume overload (spironolactone/eplerenone) and endothelial dysfunction (statins) with weight loss may benefit patients with HFpEF. We report analysis of 335 patients with HFpEF comprised of 61% female (mean age 74 ± 8) and 39% males (mean age 72 ± 7). Initial EF ranged between 50 and 77% with mean EF of 57 ± 6%. Only 15 patients were changed to metoprolol succinate, verapamil or diltiazem because of adverse side effects. Two hundred and twenty of the patients were in normal sinus rhythm when started on carvedilol, spironolactone/eplerenone and statin therapy with weight loss counseling. After 5 years, 191 patients were still on combination therapy, and only 31 (17%) had developed Atrial Fibrillation (AF). Compared to previous HFpEF trials reporting a 32% risk of developing atrial fibrillation after 4 years, our combination therapy significantly (p < 0.05) reduced the risk of developing AF over 5 years. Thus, irrespective of age and sex with comorbidities of type 2 Diabetes Mellitus (DM) and Chronic Kidney Disease (CKD), patients with HFpEF can be managed successfully with carvedilol, spironolactone/eplerenone and statins with a clinical benefit being a reduced risk of developing AF. We consider these data hypothesis-generating and hope these results will be tested further in database analyses and clinical trials.

Despite advancing medical technology, Heart Failure (HF) is still a prevalent disease with high mortality and high health expenditure. To improve patient outcome and prognosis, it is important to identify the association of risk factors which leads to the co-morbid depression and anxiety in heart failure patients. Objectives: To determine the association of depression and/or anxiety with age, gender and ejection fraction in heart failure patients. Methods: It is an analytical cross sectional study including 323 CHF patients who visited the to the Faisalabad Institute of Cardiology hospital Out-Patient Department, 250 were males and 73 were females, mean age was 54.1 ± 9.2 years having 70 years as maximum and 25 years as minimum.  Data collection was done using Hospital Anxiety and Depression Scale (HADS) questionnaire to assess depression and anxiety. Data was analyzed using SPSS version 24. For quantitative data, mean and standard deviation was calculated and for qualitative data frequency and percentages was calculated. To measure the association of anxiety and depression with age categories, ejection fraction and gender, chi square test was used. P values less than and equal to 0.05 were taken as significant. Results: No association of depression and anxiety with gender and Left Ventricular Ejection Fraction (LVEF) was observed. However, depression and anxiety were found to be significantly associated with age Conclusions: The study concluded that age is a strong risk factor of depression and anxiety in congestive heart failure patients. Multidisciplinary health care team approach and interventions are required to cater chronic heart failure (CHF) patients to address the psychological burden.

Abstract Funding Acknowledgements Type of funding sources: None. BACKGROUND The recent Heart Failure Association (HFA) of the European Society of Cardiology (ESC) consensus guidelines on diagnosis of heart failure with preserved ejection fraction (HFpEF) have developed a simple diagnostic algorithm for clinical use. PURPOSE To assess whether echocardiogram (echo) parameters needed to assess diastolic function are routinely collected in patients referred for assessment of heart failure symptoms. METHODS Retrospective analysis of echo referrals in January 2020 were assessed for parameters of diastolic function as per step 2 of the HF-PEFF diagnostic algorithm.  Echo images and clinical reports were reviewed. Electronic records were utilised to obtain clinical history, blood results (NT-proBNP) and demographic data. RESULTS 1330 patients underwent an echo in our department during January 2020. 83 patients were referred with symptoms of heart failure without prior history of cardiac disease; 20 patients found to have impaired left ventricular (LV) function were excluded from analysis. Of the 63 patients with possible HFpEF, HF-PEFF score was low in 18, intermediate in 33 and high in 12. Median age was 68 years (range 32 to 97 years); 25% had a BMI &gt;30. There was a high prevalence of hypertension (52%), diabetes (19%) and atrial fibrillation (40%) (cf. Table 1). Body surface area (BSA) was documented in 65% of echo reports. Most echo parameters were recorded with the exception of global longitudinal strain (GLS) and indexed LV mass (cf. image 1). NT-proBNP was recorded in only 20 patients (31.7%). 12 patients with an intermediate HF-PEFF score could have been re-categorised to a high score depending on GLS and NT-proBNP (which were not recorded). CONCLUSION More than three quarters of echoes acquired in our department obtained the relevant parameters to assess diastolic function. The addition of BSA, and inclusion of NT-proBNP, and GLS would have been additive to a third of ‘intermediate’ patients to determine definite HFpEF. Our study demonstrates that the current HFA-ESC diagnostic algorithm and HF-PEFF scoring system are easy to use, highly relevant and applicable to current clinical practice.
