METHODS: For 672 enrolled patients, we collected history, LVEF, EP study and T-wave alternans testing, 24-h Holter, NT-proBNP, and the eGFR. All-cause mortality and first appropriate ICD shock were predefined endpoints. RESULTS: The 635 patients included in the final analyses were 63 ± 13 years old, 81% were male, LVEF averaged 40 ± 14%, 20% were inducible at EP study, 63% had a primary prophylactic ICD. During follow-up over 4.3 ± 1.5 years, 108 patients died (4.0% per year), and appropriate shock therapy occurred in n = 96 (3.9% per year). In multivariate regression, age (p < 0.001), LVEF (p < 0.001), NYHA functional class (p = 0.007), eGFR (p = 0.024), a history of atrial fibrillation (p = 0.011), and NT-pro-BNP (p = 0.002) were predictors of mortality. LVEF (p = 0.002), inducibility at EP study (p = 0.007), and secondary prophylaxis (p = 0.002) were identified as independent predictors of appropriate shocks. A high annualized risk of shocks of about 10% per year was prevalent in the upper quintile of the shock score. In contrast, a low annual risk of shocks (1.8% per year) was found in the lower two quintiles of the shock score. The lower two quintiles of the mortality score featured an annual mortality <0.6%. CONCLUSIONS: In a prospective ICD patient cohort, a very good approximation of mortality versus arrhythmic risk was possible using a multivariable diagnostic strategy. EP stimulation is the best test to assess risk of arrhythmias resulting in ICD shocks."],["dc.identifier.doi","10.1016/j.ijcard.2018.06.103"],["dc.identifier.pmid","29983251"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15929"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59764"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.intern","In goescholar not merged with http://resolver.sub.uni-goettingen.de/purl?gs-1/15360 but duplicate"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/241526/EU//EUTRIGTREAT"],["dc.relation.issn","1874-1754"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.access","openAccess"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.subject.ddc","610"],["dc.subject.mesh","Aged"],["dc.subject.mesh","Aged, 80 and over"],["dc.subject.mesh","Arrhythmias, Cardiac"],["dc.subject.mesh","Cohort Studies"],["dc.subject.mesh","Death, Sudden, Cardiac"],["dc.subject.mesh","Defibrillators"],["dc.subject.mesh","Defibrillators, Implantable"],["dc.subject.mesh","Female"],["dc.subject.mesh","Follow-Up Studies"],["dc.subject.mesh","Humans"],["dc.subject.mesh","Male"],["dc.subject.mesh","Middle Aged"],["dc.subject.mesh","Mortality"],["dc.subject.mesh","Multivariate Analysis"],["dc.subject.mesh","Natriuretic Peptide, Brain"],["dc.subject.mesh","Peptide Fragments"],["dc.subject.mesh","Prospective Studies"],["dc.subject.mesh","Risk Factors"],["dc.title","Differential multivariable risk prediction of appropriate shock versus competing mortality - A prospective cohort study to estimate benefits from ICD therapy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Upon excitation, ATs rapidly activate intracellular Ca2+ release and sarcomeric contraction through extensive AT junctions, a cell-specific atrial mechanism. While AT junctions with the sarcoplasmic reticulum contain unusually large clusters of ryanodine receptor 2 (RyR2) Ca2+ release channels in mouse AMs, it remains unclear if similar protein networks and membrane structures exist across species, particularly those relevant for atrial disease modeling. Objective: To examine and quantitatively analyze the architecture of AT membrane structures and associated Ca2+ signaling proteins across species from mouse to human. Methods and Results: We developed superresolution microscopy (nanoscopy) strategies for intact live AMs based on a new custom-made photostable cholesterol dye and immunofluorescence imaging of membraneous structures and membrane proteins in fixed tissue sections from human, porcine, and rodent atria. Consistently, in mouse, rat, and rabbit AMs, intact cell-wide tubule networks continuous with the surface membrane were observed, mainly composed of ATs. Moreover, co-immunofluorescence nanoscopy showed L-type Ca2+ channel clusters adjacent to extensive junctional RyR2 clusters at ATs. However, only junctional RyR2 clusters were highly phosphorylated and may thus prime Ca2+ release at ATs, locally for rapid signal amplification. While the density of the integrated L-type Ca2+ current was similar in human and mouse AMs, the intracellular Ca2+ transient showed quantitative differences. Importantly, local intracellular Ca2+ release from AT junctions occurred through instantaneous action potential propagation via transverse tubules (TTs) from the surface membrane. Hence, sparse TTs were sufficient as electrical conduits for rapid activation of Ca2+ release through ATs. Nanoscopy of atrial tissue sections confirmed abundant ATs as the major network component of AMs, particularly in human atrial tissue sections. Conclusion: AT junctions represent a conserved, cell-specific membrane structure for rapid excitation-contraction coupling throughout a representative spectrum of species including human. Since ATs provide the major excitable membrane network component in AMs, a new model of atrial \"super-hub\" Ca2+ signaling may apply across biomedically relevant species, opening avenues for future investigations about atrial disease mechanisms and therapeutic targeting."],["dc.identifier.doi","10.3389/fphys.2018.01227"],["dc.identifier.pmid","30349482"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15400"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/107860"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/217"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | A05: Molekulares Imaging von kardialen Calcium-Freisetzungsdomänen"],["dc.relation","SFB 1002 | A09: Lokale molekulare Nanodomänen-Regulation der kardialen Ryanodin-Rezeptor-Funktion"],["dc.relation","SFB 1002 | S02: Hochauflösende Fluoreszenzmikroskopie und integrative Datenanalyse"],["dc.relation","SFB 1002 | A13: Bedeutung einer gestörten zytosolischen Calciumpufferung bei der atrialen Arrhythmogenese bei Patienten mit Herzinsuffizienz (HF)"],["dc.relation.eissn","1664-042X"],["dc.relation.workinggroup","RG Brandenburg"],["dc.relation.workinggroup","RG Lehnart (Cellular Biophysics and Translational Cardiology Section)"],["dc.relation.workinggroup","RG Sossalla (Kardiovaskuläre experimentelle Elektrophysiologie und Bildgebung)"],["dc.relation.workinggroup","RG Voigt (Molecular Pharmacology)"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","610"],["dc.title","Axial Tubule Junctions Activate Atrial Ca2+ Release across Species"],["dc.type","research_data"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The contractility of the heart muscle is influenced by pre-load and after-load. Because of the effect of pre-load vs. after-load on these mechanisms in not completely understood, we studied the effect in isolated muscle strips. Methods and results Progressive stretch lead to an increase in shortening/force development under isotonic (only pre-load) and isometric conditions (pre- and after-load). Muscle length with maximal function was reached earlier under isotonic (Lmax-isotonic) compared with isometric conditions (Lmax-isometric) in nonfailing rabbit, in human atrial and in failing ventricular muscles. Also, SR after stretch from slack to Lmax-isotonic was comparable under isotonic and isometric conditions (human: isotonic 10 ± 4%, isometric 10 ± 4%). Moreover, a switch from isotonic to isometric conditions at Lmax-isometric showed no SR proving independence of after-load. To further analyse the degree of SR on the total contractile performance at higher pre-load muscles were stretched from slack to 98% Lmax-isometric under isotonic conditions. Thereby, the SR was 60 ± 9% in rabbit and 51 ± 14% in human muscle strips. Conclusions This work shows that the acute contractile response largely depends on the degree and type of mechanical load. Increased filling of the heart elevates pre-load and prolongs the isotonic part of contraction. The reduction in shortening at higher levels of pre-load is thereby partially compensated by the pre-load-induced SR. After-load shifts the contractile curve to a better ‘myofilament function’ by probably influencing thin fibers and calcium sensitivity, but has no effect on the SR."],["dc.identifier.doi","10.1002/ehf2.12164"],["dc.identifier.pmid","29154423"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14815"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59034"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/305"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | A03: Bedeutung CaMKII-abhängiger Mechanismen für die Arrhythmogenese bei Herzinsuffizienz"],["dc.relation","SFB 1002 | D01: Erholung aus der Herzinsuffizienz – Einfluss von Fibrose und Transkriptionssignatur"],["dc.relation.issn","2055-5822"],["dc.relation.workinggroup","RG Sossalla (Kardiovaskuläre experimentelle Elektrophysiologie und Bildgebung)"],["dc.relation.workinggroup","RG Toischer (Kardiales Remodeling)"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.subject.ddc","610"],["dc.title","The contractile adaption to preload depends on the amount of afterload"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
