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.

Some studies support the use of beta-AR-antagonists in HF patients with preserved ejection fraction (EF) but impaired relaxation similar to diastolic dysfunction seen in HCM patients (Lund et al., 2014). All authors critically discussed the results, and reviewed and approved the manuscript before submission. Current pharmacological treatment of HCM mainly relies on beta-adrenoceptor (AR) and Ca2+ channel blockers, which improve clinical symptoms, partially prevent arrhythmias and improve diastolic dysfunction by prolonging left ventricular (LV) filling time and reducing outflow tract obstruction (Maron et al., 2003; Gersh et al., 2011; Spoladore et al., 2012; Hamada et al., 2014; Tardiff et al., 2015).

Background: Impaired coronary flow reserve (CFR) is a significant predictor of poor prognosis in patients with idiopathic dilated cardiomyopathy (IDC). (2) Our study does not explain the precise mechanism of Ca2+-desensitization of nebivolol in mouse heart tissue. Comparisons were performed by paired or unpaired Student's t-test and with one-way ANOVA, followed by Bonferroni's post-test as indicated in the figure legends. This initiated the design of a still ongoing trial (https://clinicaltrials.gov/ct2/show/NCT02619526) investigating the effects of nebivolol and carvedilol on diastolic function of the left ventricle in older HF patients with preserved EF (Park and Park, 2016).

Hypertrophic cardiomyopathy (HCM) is one of the most common genetic heart disorders, with a prevalence of 1 in 200 (0.6% of the general population). In WT strips, only incubation with 10 μM (by extra sum-of-squares F-test) shifted the force-Ca2+ relationship to the right resulting in a lower pCa50, whereas in KI strips both 1 and 10 μM lowered pCa50 (Figures 2A,B) indicating myofilament Ca2+ desensitization.

Further studies should investigate the exact target and mechanism for Ca2+ desensitization in mouse cardiac tissues in order to be able to develop modified compounds with even more potency and specificity for use in human tissue. The findings are contradictory but could be explained by either differences (i) between species (rabbit vs. mouse vs. human), (ii) in experimental setups, (iii) the functional status of the tissues (non-failing vs. failing), or (iv) a combination of it.
