Fig 5. Active force (% of baseline value) variation of left ventricle papillary muscle exposed to isoproterenol in diabetic rats pretreated with statin (atorvastatin, 50 mg kg-1 day-1) during 15 days (8 rats per group) with or without L-NAME administration.

Control refers to diabetic rats not receiving statin. AF/s = active force normalized per cross-sectional area during isometric contraction. Data are expressed as mean ± SD. NS: non-significant.
