Abstract Background: Diastolic dysfunction has been reported in patients with COVID-19. Due to the role of N-terminal pro-brain natriuretic peptide (NT-proBNP) in the diagnosis of heart failure, this study investigated the relationship between serum NT-proBNP levels and diastolic heart failure in COVID-19 patients.Methods: This descriptive-analytical study was performed at Ayatollah Rouhani Hospital in Babol. Fifty-four patients with confirmed COVID-19 diagnosis who were admitted to the ICU were included in the study. The primary outcome was the relationship and predictive role of NT-proBNP and diastolic heart failure in patients with severe SARS-COV-2 infection. Patients with pro BNP >125 pg/mL underwent echocardiography and the relationship between echocardiographic indices and NT-proBNP was assessed as a secondary outcome.Results: Our study showed that plasma NT-proBNP levels in patients with increased diastolic dysfunction were associated with disease severity. It was also found that the cut-off point of NT-proBNP = 799 pg/mL could be a predictor of diastolic dysfunction grades two and three. In this study, patients with a serum NT-proBNP level equal or above 799 had 37 times higher chance of having diastolic dysfunction than those with a serum NT-proBNP level below 799. Patients with NT-proBNP above 556 had RV_EA> 2 in echocardiography, indicating increased right-sided filling pressures.Conclusion: Despite the confounding factors in the interpretation of the pro BNP level in COVID-19, its level can be used to estimate the presence of high-grade diastolic heart failure on the left and right sides of the heart and the presence of high filling pressures. Lower levels of NT-proBNP are associated with right-sided diastolic failure.

With stress echo (SE) 2020 study, a new standard of practice in stress imaging was developed and disseminated: the ABCDE protocol for functional testing within and beyond CAD. ABCDE protocol was the fruit of SE 2020, and is the seed of SE 2030, which is articulated in 12 projects: 1-SE in coronary artery disease (SECAD); 2-SE in diastolic heart failure (SEDIA); 3-SE in hypertrophic cardiomyopathy (SEHCA); 4-SE post-chest radiotherapy and chemotherapy (SERA); 5-Artificial intelligence SE evaluation (AI-SEE); 6-Environmental stress echocardiography and air pollution (ESTER); 7-SE in repaired Tetralogy of Fallot (SETOF) ; 8-SE in post-COVID-19 (SECOV); 9: Recovery by stress echo of conventionally unfit donor good hearts (RESURGE); 10-SE for mitral ischemic regurgitation (SEMIR); 11-SE in valvular heart disease (SEVA); 12-SE for coronary vasospasm (SESPASM). The study aims to recruit in the next 5 years (2021–2025) ≥10,000 patients followed for ≥5 years (up to 2030) from ≥20 quality-controlled laboratories from ≥10 countries. In this COVID-19 era of sustainable health care delivery, SE2030 will provide the evidence to finally recommend SE as the optimal and versatile imaging modality for functional testing anywhere, any time, and in any patient.

Amyloidosis is a group of diseases in which amyloid fibrils build up in tissues, leading to organ dysfunction. Cardiac involvement is observed in immunoglobulin light chain amyloidosis (AL) and transthyretin amyloidosis (ATTR) and, when it occurs, the prognosis worsens. Cardiac tissue infiltration can lead to restrictive cardiomyopathy with clinical signs of diastolic heart failure, without reduction of ejection fraction (HFpEF). The aim of multiple and less invasive diagnostic tests is to discern peculiar characteristics and reach the diagnosis without performing an invasive endomyocardial biopsy. These diagnostic tools allow early diagnosis, and they are crucial to best benefit from target therapy. In this review article, we describe the mechanism behind amyloid fibril formation, infiltration of tissues, and consequent clinical signs, focusing on the diagnostic tools and the red flags to obtain a diagnosis.

During these more than 20 years of evolution in understandings of the mechanisms of heart failure (HF) with preserved fractional ejection, there has been a rich variety of terminology, including „diastolic heart failure“, „heart failure with preserved systolic function“ and „heart failure with preserved fraction“. By defi nition, the latter term “ejection fraction-induced heart failure” proved to be the most appropriate and was accepted as the most correct, as the presence of diastolic dysfunction is not unique only to this group and exists in these patients, albeit subclinically and discrete disturbance in the longitudinal systolic function of the left ventricle against the background of the preserved ejection fraction. The problem, however, is not in the value of the ejection fraction or in the paradox of the combination of a well-functioning left ventricle and classic symptoms of heart failure, but in the non-infl uence of the prognosis of these patients in the way it is in patients with suppressed EF. Unlike patients with heart failure with a reduced ejection fraction, the prognosis and results in patients with HF with preserved EF do not mark the expected results and so far there are not enough effective and promising therapies.

Relevance. Cardiotrophin-1 (CT-1) is a member of interleukin-6 (IL-6) superfamily and is associated with cardiovascular pathology. The production of CT-1 increases in response to myocardial wall stretching and increase in its rigidity and is also modulated by a wide range of neurohormones and peptides, which allows to monitor CT-1 as a marker of biomechanical stress. However, the prognostic significance of CT-1 in patients with diastolic heart failure with hypertrophic cardiomyopathy (HCM) remains poorly understood.Objective. To study the blood serum cardiotrophin-1 contents and their relationships with NT-proBNP in patients with obstructive hypertrophic cardiomyopathy and in patients with severe left ventricular (LV) dysfunction.Material and Methods. The study comprised a total of 76 patients with obstructive HCM and 31 patients with severe LV dysfunction. The group of patients with HCM comprised patients with obstructive form; the group of patients with severe LV dysfunction included patients with the third type of post-infarction LV remodeling and ejection fraction (EF) of less than 30%. The determination of cardiotrophin-1 and highly sensitive C-reactive protein was carried out by the enzyme immunoassay. The study of NT-proBNP content in blood serum was performed by multiplex immunoassay using the FLEXMAP 3D Luminex Corporation system.Results. The content of cardiotrophin-1 in the blood serum of patients with obstructive HCM was higher than in the group of patients with severe LV dysfunction. The study of NT-proBNP concentrations in the blood serum showed increases in the content in both groups of patients. The median concentrations of NT-proBNP and C-reactive protein in patients with severe LV dysfunction were increased compared to the median concentration in patients with obstructive HCM.Conclusion. The study showed an increase in cardiotrophin-1 content in the blood serum in patients with obstructive HCM with chronic diastolic heart failure. The increase in cardiotrophin-1 content was directly associated with the increase in NTproBNP level in patients with obstructive HCM with chronic diastolic heart failure.

Background: Cerebrovascular Accident (CVA) is the second cause of death and disability in the world. Heart failure can co-occur with CVA and increases the risk of death and disability in patients. Objectives: This study aimed to evaluate the prevalence of heart failure in patients with ischemic stroke. Materials & Methods: In this cross-sectional study, the information of patients with ischemic stroke was collected in 2016 from their files. They were referred to the Emergency Department of Poursina Hospital. Statistical analysis of data was performed by using descriptive statistical methods. Estimation of mean and frequency was done by SPSS v. 22. Results: A total of 291 patients were recruited in the study. Also, 157 patients (54%) were male, and 134 (46%) were female. The Mean±SD age of patients was 61.68 (12.98) years. Systolic heart failure prevalence was 59.8%, and diastolic heart failure was 65.7%. Conclusion: Based on the findings, more than half of the patients with ischemic stroke also develop heart failure. Therefore, it is recommended that the patient be evaluated and treated for heart failure when faced with ischemic stroke.
