Background: Left ventricular (LV) function in acute perimyocarditis is variable. We evaluated LV function in patients with acute perimyocarditis with speckle tracking. Methods: Thirty‐eight patients with acute perimyocarditis and 20 normal subjects underwent echocardiographic examination. Three‐layers strain and twist angle were assessed with a speckle tracking. Follow‐up echo was available in 21 patients. Results: Strain was higher in normal subjects than in patients with perimyocarditis. Twist angle was reduced in perimyocarditis—10.9°± 5.4 versus 17.6°± 5.8, P < 0.001. Longitudinal strain and twist angle were higher in normal subjects than in patients with perimyocarditis and apparently normal LV function. Follow‐up echo in 21 patients revealed improvement in longitudinal strain. Conclusions: Patients with acute perimyocarditis have lower twist angle, longitudinal and circumferential strain. Patients with perimyocarditis and normal function have lower longitudinal strain and twist angle. Short‐term follow‐up demonstrated improvement in clinical parameters and longitudinal strain despite of residual regional LV dysfunction. (Echocardiography 2011;28:548‐555)
