nebivolol for hypertrophic cardiomyopathy

J. Thorac. Interspecies- or setup-dependent differences have been reported in permeabilized strip experiments with other drug interventions (Lues et al., 1988; Edes et al., 1995). There are conflicting reports concerning the effects of nebivolol on maximal force development and myofilament Ca2+ sensitivity in cardiac muscle strips. The principal inclusion criteria were (1) NYHA class II–IV CHF and (2) a left ventricular ejection fraction (LVEF) ≤35%. Cockcroft, J. R., Chowienczyk, P. J., Brett, S. E., Chen, C. P., Dupont, A.

It also affects the L-arginine/NO pathway causing vasodilatation by increasing endothelial NO release [9]. Nebivolol, carvedilol and metoprolol do not influence cardiac Ca2+ sensitivity. Res. Epub 2017 May 19. Med. Nebivolol is a third-generation beta-AR antagonist that exhibits vasodilating properties, most likely due to stimulation of nitric oxide synthase (Cockcroft et al., 1995). Physiol. J. Pharmacol. Arch. Whereas Zeitz et al. 1, 2 Hallmarks of the disease process include a hypercontractile state resulting from increased ATPase sensitivity to Ca 2+, 3, 4 faster cross-bridge sliding velocity, 5, 6 and higher force production by individual cross-bridges. Since nebivolol has been reported to desensitize human myofilaments for Ca2+ and since both 1 and 10 μM nebivolol had induced a right-ward shift of the force-pCa curves in Mybpc3 KI cardiac muscle strips we sought to investigate whether it would also affect myofilament Ca2+ sensitivity in human HCM tissue. Nebivolol is a third-generation, highly cardioselective and lipophilic β1-adrenoceptor antagonist.

Nebivolol has an unusual profile compared to other medications, in that its effects may be related to release of a substance called nitric oxide. Given the hypercontractile phenotype mentioned above, these pleiotropic actions predestine it for HCM treatment. Am. used non-failing cardiac tissue from rabbit and explanted human tissue from end-stage failing myocardium from patients undergoing heart transplantation and saw an effect in tissues of both species. reported that 1 μM nebivolol lowered maximal force development and myofilament Ca2+ sensitivity in skinned trabeculae (Zeitz et al., 2000), Bundkirchen and colleagues did not observe such an effect at 10 μM (Bundkirchen et al., 2001).

Background: Hypertrophic cardiomyopathy (HCM) patients often present with diastolic dysfunction and a normal to supranormal systolic function. Human myocardial samples were obtained from three HCM patients carrying heterozygous MYBPC3 mutations (c.1960C>T, c.2308G>A, c.2234A>G) who underwent septal myectomy due to outflow tract obstruction. Since nebivolol has been reported to lower maximal force development and to desensitize rabbit and human cardiac myofilaments (Zeitz et al., 2000; Janssen et al., 2001), we investigated nebivolol effects on myofilament Ca2+ sensitivity in cardiac muscle strips of Mybpc3 KI mice with an increased myofilament Ca2+ sensitivity (Vignier et al., 2009; Fraysse et al., 2012; Flenner et al., 2016; Friedrich et al., 2016).

One well established pathomechanism for the hypercontractile phenotype frequently observed in HCM patients and several HCM mouse models is an increased myofilament Ca2+ sensitivity. I do know that the ablation success is about 60% given the underlying cardiomyopathy. Whether such an indirect effect is the main reason for a decrease in myofilament Ca2+ sensitivity or another direct mechanism on the moyfilaments, such as binding to the C-terminal region of cardiac troponin C altering the interaction between cTnC and cTnI as in the case of the positive control compound EGCg (Liou et al., 2008; Robertson et al., 2009), exists, remains to be shown.

Green tea catechin normalizes the enhanced Ca2+ sensitivity of myofilaments regulated by a hypertrophic cardiomyopathy-associated mutation in human cardiac troponin I (K206I). One well established pathomechanism for the hypercontractile phenotype frequently observed in HCM patients and several HCM mouse models is an increased myofilament Ca2+ sensitivity (Morimoto et al., 1998; Robinson et al., 2007; Huke and Knollmann, 2010; Kimura, 2010; Fraysse et al., 2012; Moore et al., 2012; van Dijk et al., 2012; Barefield et al., 2014; Elliott et al., 2014; Flenner et al., 2016; Friedrich et al., 2016). The aim of this study was to evaluate the effect of nebivolol in cardiac muscle strips of an established HCM Mybpc3 mouse model. (3) The Ca2+ desensitizing effect of nebivolol in mouse tissues occurred at concentrations which were above the plasma concentrations (0.8–3.7 nM) observed in humans (Stoschitzky et al., 2004; Prisant, 2008). 52, 1299–1307. The Hypertrophic Cardiomyopathy Association shall not be liable for any information provided herein. (2004). The E3 ubiquitin ligase Asb2beta is downregulated in a mouse model of hypertrophic cardiomyopathy and targets desmin for proteasomal degradation. Since it was shown to attenuate hydroxyl radical-induced myocardial damage which has been associated with altered intracellular calcium handling and calcium overload of the myocytes (Josephson et al., 1991; Janssen et al., 1999; Piccini et al., 2012), it was proposed that nebivolol has direct free-radical scavenging properties (Janssen et al., 1999). Neither 1 nor 10 μM nebivolol had an effect on Ca2+ sensitivity in cardiac muscle strips of three HCM patients with MYBPC3 mutations, whereas epigallocatechin-gallate induced a right shift in the force-Ca2+ curve.

In contrast, 30 μM of the positive control compound EGCg, which has been suggested to alter the interaction between cardiac troponin C and I and therefore the sensitivity of the myofilaments to Ca2+ (Liou et al., 2008; Robertson et al., 2009), induced a rightward shift in the force-Ca2+ curve in human HCM strips.
