Hospitalized patients with heart failure: the impact of anxiety, fatigue, and therapy adherence on quality of life. ARCHIVES OF MEDICAL SCIENCES. ATHEROSCLEROTIC DISEASES 2020; 4:e268-e279. [PMID: 32368682 PMCID: PMC7191938 DOI: 10.5114/amsad.2019.90257] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/18/2019] [Accepted: 10/12/2019] [Indexed: 01/25/2023]
Abstract
Introduction Heart failure (HF) is a major global health problem associated with increased morbidity and mortality and reduced quality of life (QoL). The aim of the study was to assess the impact of anxiety, fatigue and adherence to therapeutic guidelines on HF patients' QoL. Material and methods A hundred and twenty hospitalized HF patients were enrolled in the study. Data collection was performed by completion of the Minnesota Living With Heart Failure Questionnaire (MLHFQ), the Greek version of the Modified Fatigue Impact Scale (MFIS-Greek), the Zung Self-Rating Anxiety Scale (SAS) and a questionnaire that measured adherence to therapeutic guidelines. Results Data analysis showed moderate levels of anxiety and high levels of adherence to therapeutic guidelines as well as moderate to large effects of HF on patients' fatigue and QoL. A statistically significant positive linear association was observed between anxiety and QoL (rho > 0.6) as well as fatigue and QoL (rho > 0.3). An increase in the anxiety or fatigue score indicated an increase also in the QoL score, meaning that the more anxiety and fatigue a patient felt the worse the QoL also was. Moreover, a statistically significant negative linear association was observed between adherence to therapeutic guidelines and QoL (rho < -0.2). An increase in adherence score indicated a decrease in QoL score, meaning that the more adherent a patient was the better was the QoL. Conclusions The present findings suggest that QoL may be improved when adherence to therapy is increased and fatigue and anxiety are alleviated.

Abstract
To identify the mechanism and functions of IRX1 in heart failure (HF) and provide evidence for new therapies. Bioinformatic analysis was performed to select target genes in HF cells compared to normal groups. Experimental rats were treated in a controllable manner to explore how IRX1 methylation accounted for this disease in vivo. Cardiac ultrasonic and morphologic examinations were conducted to test the mouse heart and evaluate the degree of cardiac impairment at in the level of organization. GSEA analysis revealed the relative enrichment of functions. Immunofluorescent assays, western blotting and qRT-PCR were used to determine the DNA methylation and expression levels. IRX1 was hypermethylated in heart failure and identified as a target gene by bioinformatic analysis. Transverse aortic constriction (TAC) induced heart failure in rats, while 5-aza-2'-deoxycytidine (5-Aza) alleviated heart failure in rats according to medical cardiac indexes. Western blotting and qRT-PCR revealed that a conspicuous difference in the expression of IRX1 and CXCL14 between HF and normal cardiac cells. As a result of gene methylation, left ventricular hypertrophy and cardiac fibrosis is usually accompanied by heart failure. Moreover, is the results implied that the demethylation of IRX1 improves heart failure in vivo and in vitro. IRX1 methylation induced damaged cardiac function and even heart failure, which has important implications for HF treatment and diagnosis.

Abstract
Chronic Heart Failure (CHF) is a complex clinical syndrome with a high incidence worldwide. Although various types of pharmacological and device therapies are available for CHF, the prognosis is not ideal, for which, the control of increased Heart Rate (HR) is critical. Recently, a bradycardic agent, ivabradine, is found to reduce HR by inhibiting the funny current (If). The underlying mechanism states that ivabradine can enter the Hyperpolarization-activated Cyclic Nucleotide-gated (HCN) channels and bind to the intracellular side, subsequently inhibiting the If. This phenomenon can prolong the slow spontaneous phase in the diastolic depolarization, and thus, reduce HR. The clinical trials demonstrated the significant effects of the drug on reducing HR and improving the symptoms of CHF with fewer adverse effects. This review primarily introduces the chemical features and pharmacological characteristics of ivabradine and the mechanism of treating CHF. Also, some expected therapeutic effects on different diseases were also concluded. However, ivabradine, as a typical If channel inhibitor, necessitates additional research to verify its pharmacological functions.

Abstract
Heart failure is a common clinical syndrome and a global health priority. The burden of heart failure is increasing at an alarming rate worldwide as well as in India. Heart failure not only increases the risk of mortality, morbidity and worsens the patient's quality of life, but also puts a huge burden on the overall healthcare system. The management of heart failure has evolved over the years with the advent of new drugs and devices. This document has been developed with an objective to provide standard management guidance and simple heart failure algorithms to aid Indian clinicians in their daily practice. It would also inform the clinicians on the latest evidence in heart failure and provide guidance to recognize and diagnose chronic heart failure early and optimize management.
