Int J Gen Med 2023; 16:3491-3501. [PMID: 37601803 PMCID: PMC10438439 DOI: 10.2147/ijgm.s418674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 08/04/2023] [Indexed: 08/22/2023] Open
Abstract
Background Non-valvular atrial fibrillation (NVAF) is associated with increased stroke in elderly populations, yet anticoagulant therapy is underutilized. We analyzed clinical characteristics and anticoagulation treatment rates of elderly NVAF patients hospitalized in Dali, China, to identify potential contributing factors. Methods We collected data for 155 elderly patients with NVAF aged ≥60 years, from July 01, 2020, to December 31, 2021. We analyzed the awareness rate, clinical characteristics, and anticoagulant treatment rate of atrial fibrillation (AF), and identified factors influencing treatment. Patients were followed up one year after discharge to assess vital status, cardiovascular events, and anticoagulation therapy status. Results Among 155 patients, 52.26% were female, and the average age was 75.77 years. The awareness rate of AF was 47.74% at admission, and only 21.94% received anticoagulant therapy. After discharge, the rate of anticoagulant therapy significantly increased to 70.97%, and 89.09% used new oral anticoagulants. Thromboembolic history and persistent AF predicted anticoagulant therapy at discharge, while male gender, previous bleeding history, and antiplatelet therapy predicted non-anticoagulant therapy. Out of 133 patients who completed a one-year follow-up, 23.31% died, 3.01% had strokes, and 3.01% experienced bleeding. Anticoagulant therapy decreased to 51.96% during the follow-up year. Conclusion Our findings highlight the low awareness rate and anticoagulant treatment rate, and high mortality among elderly NVAF patients in Dali. The development of comprehensive intervention strategies is critical to standardize AF management and improve prognosis.

Front Cardiovasc Med 2022; 8:838680. [PMID: 35155623 PMCID: PMC8826966 DOI: 10.3389/fcvm.2021.838680] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Accepted: 12/31/2021] [Indexed: 12/13/2022] Open
Abstract
Background/Aims To explore the imaging changes and related risk factors of heart failure (HF) patients with cognitive impairment (CI). Methods A literature search was systematically carried out in PubMed, Web of Science, Embase, and Cochrane Library. In this systematic review, important relevant information was extracted according to the inclusion and exclusion criteria. The methodological quality was assessed by three scales according to the different study types. Results Finally, 66 studies were included, involving 33,579 patients. In the imaging changes, the severity of medial temporal lobe atrophy (MTA) and the decrease of gray Matter (GM) volume were closely related to the cognitive decline. The reduction of cerebral blood flow (CBF) may be correlated with CI. However, the change of white matter (WM) volume was possibly independent of CI in HF patients. Specific risk factors were analyzed, and the data indicated that the increased levels of B-type natriuretic peptide (BNP)/N-terminal pro-B-type natriuretic peptide (NT-proBNP), and the comorbidities of HF, including atrial fibrillation (AF), diabetes mellitus (DM) and anemia were definitely correlated with CI in patients with HF, respectively. Certain studies had also obtained independent correlation results. Body mass index (BMI), depression and sleep disorder exhibited a tendency to be associated with CI. Low ejection fraction (EF) value (<30%) was inclined to be associated with the decline in cognitive function. However, no significant differences were noted between heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) in cognitive scores. Conclusion BNP/NT-proBNP and the comorbidities of HF including AF, DM and anemia were inextricably correlated with CI in patients with HF, respectively. These parameters were independent factors. The severity of MTA, GM volume, BMI index, depression, sleep disorder, and low EF value (<30%) have a disposition to associated with CI. The reduction in the CBF volume may be related to CI, whereas the WM volume may not be associated with CI in HF patients. The present systematic review provides an important basis for the prevention and treatment of CI following HF.

[Observational study of the prevalence of non-valvular atrial fibrillation and ischemic stroke and the factors associated with non-valvular atrial fibrillation in hypertensive patients: about 2887 cases]. Pan Afr Med J 2021; 38:31. [PMID: 33777299 PMCID: PMC7955596 DOI: 10.11604/pamj.2021.38.31.25569] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Accepted: 12/20/2020] [Indexed: 01/18/2023] Open
Abstract
Introduction high blood pressure (HBP), atrial fibrillation (AF) and ischemic stroke are three public health problems. The purpose of this study was to determine the prevalence of AF and ischemic stroke in hypertensive patients and the factors associated with the occurrence of non-valvular AF in these patients. Methods we used data collected in the Department of Cardiology at the University Hospital of Sfax as a part of National Tunisian Registry of Hypertension. We examined the associations between different socio-demographic, clinical, paraclinical, and therapeutic variables and AF in hypertensive patients using logistic regression models. Results our sample consisted of 2887 patients with a sex ratio of 0.95. The average age of patients was 65 years (±11). AF was found in 230 patients (8%), while ischemic stroke was found in 152 patients (5.3%). Multivariate analysis highlighted that independent factors associated with an increase in the prevalence of AF were: advanced age (p = 0,001, Odds Ratio (OR) = 1,647, 95% confidence interval ( CI): 1,1227-2,213), the detection of left ventricular hypertrophy (LVH) on cardiac ultrasound (p= 0,004, OR= 2,140, 5%CI 9: 1,281-3,576), and left ventricular ejection fraction (LVEF) < 50% (p<0,001, OR=4,677, 95% CI: 2,715 and 8.057). Conclusion this study confirms that there is a direct and independent relationship between high blood pressure, advanced age, LVH and AF. AF in patients with high blood pressure is a disease progression leading to an increased risk of ischemic stroke. Optimal high blood pressure control is a priority in hypertensive patients, especially in the elderly, aiming at preventing the risk of AF and ischemic stroke.

Isaac E, Cooper SM, Jones SA, Loubani M. Do age-associated changes of voltage-gated sodium channel isoforms expressed in the mammalian heart predispose the elderly to atrial fibrillation? World J Cardiol 2020; 12:123-135. [PMID: 32431783 PMCID: PMC7215965 DOI: 10.4330/wjc.v12.i4.123] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2019] [Revised: 01/18/2020] [Accepted: 03/15/2020] [Indexed: 02/06/2023] Open
Abstract
Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide. The prevalence of the disease increases with age, strongly implying an age-related process underlying the pathology. At a time when people are living longer than ever before, an exponential increase in disease prevalence is predicted worldwide. Hence unraveling the underlying mechanics of the disease is paramount for the development of innovative treatment and prevention strategies. The role of voltage-gated sodium channels is fundamental in cardiac electrophysiology and may provide novel insights into the arrhythmogenesis of AF. Nav1.5 is the predominant cardiac isoform, responsible for the action potential upstroke. Recent studies have demonstrated that Nav1.8 (an isoform predominantly expressed within the peripheral nervous system) is responsible for cellular arrhythmogenesis through the enhancement of pro-arrhythmogenic currents. Animal studies have shown a decline in Nav1.5 leading to a diminished action potential upstroke during phase 0. Furthermore, the study of human tissue demonstrates an inverse expression of sodium channel isoforms; reduction of Nav1.5 and increase of Nav1.8 in both heart failure and ventricular hypertrophy. This strongly suggests that the expression of voltage-gated sodium channels play a crucial role in the development of arrhythmias in the diseased heart. Targeting aberrant sodium currents has led to novel therapeutic approaches in tackling AF and continues to be an area of emerging research. This review will explore how voltage-gated sodium channels may predispose the elderly heart to AF through the examination of laboratory and clinical based evidence.
