MYH14 and myocarditis: Mice with late-phase myocarditis (28 days after first injection of myosin and CFA) had a significantly impaired ejection fraction (mean 31.97%; standard deviation (SD) 6.136%) compared to control mice only injected with myosin (mean 47.57%; SD 4.204%) and also compared to mice with early myocarditis (9 days after first injection of myosin and CFA; mean 52.66%; SD 2.874%) (Figure 3A) as ejection fraction on day 9 remained on the baseline level (Figure S1A).
