1Do age-associated changes of voltage-gated sodium channel isoforms expressed in the mammalian heart predispose the elderly to atrial fibrillation?显示文摘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.Na_v1.5 is the predominant cardiac isoform,responsible for the action potential upstroke.Recent studies have demonstrated that Na_v1.8(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 Na_v1.5 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 Na_v1.5 and increase of Na_v1.8 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.Emmanuel Isaac Stephanie M Cooper Sandra A Jones Mahmoud Loubani 2020World Journal of Cardiology2020,12,4:3
2Diabetes mellitus, revascularization and outcomes in elderly patients with myocardial infarction-related cardiogenic shock显示文摘Background The prognostic role of diabetes mellitus(DM)in elderly patients with myocardial infarction-related cardiogenic shock(MI-CS)remains controversial.Little information exists about the impact of intensive cardiac care unit(ICCU)and revascularization on outcomes of elderly patients with MI-CS.We aimed to assess the prognostic impact of DM according to age in patients with MI-CS,and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages.Methods Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System’s Basic Data Set.Centers were classified according to their availability of ICCU.Main outcome measured was in-hospital mortality.Results A total of 23,590 episodes of MI-CS were identified,of whom 12,447(52.8%)were in patients aged≥75 years.The impact of DM on in-hospital mortality was different among age subgroups.While in younger patients,DM was associated to a higher mortality risk(0.52 vs.0.47,OR=1.12,95%CI:1.06–1.18,χ^2<0.001),this association became non-significant in older patients(0.76 vs.0.81,χ^2=0.09).Adjusted mortality rate of MI-CS aged≥75 years was lower in patients admitted to hospitals with ICCU(adjusted mortality rate:74.2%vs.77.7%,P<0.001)and in patients undergoing revascularization(74.9%vs.77.3%,P<0.001).Conclusions Prognostic impact of DM in patients with MI-CS was different according to age,with a significantly lower impact at older ages.The availability of ICCU and revascularization were associated with better outcomes in these complex patients.Miquel Gual Albert Ariza-Solé María García Márquez Cristina Fernández JoséL Bernal Francesc Formiga María-Isabel Barrionuevo JoséC Sánchez-Salado Victòria Lorente Júlia Pascual Isaac Llaó Oriol Alegre Angel Cequier Javier Elola 2020Journal of Geriatric Cardiology2020,17,10:2
