The new direct-acting antiviral drugs (DAA) proved to be more effective with fewer side effects compared to interferon in eradicating HCV, but their effect on myocardium is still questionable. In order to get some answers for such question, two-dimensional speckle tracking echocardiography (2D-STE) was studied before and after treatment with different DAA regimens in HCV patients with either mildly impaired or normal basic left ventricular ejection fraction (LVEF).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Global longitudinal strain (GLS) significantly worsened after finishing antiviral treatment in patients with basic impairment of LVEF (<jats:italic>n<\/jats:italic> = 100) and those with normal basic LVEF (<jats:italic>n<\/jats:italic> = 20) [<jats:italic>p<\/jats:italic> = 0.006 and 0.039, respectively]; also, segmental strain showed significant worsening of many segments.
