Effects of 3 months of diesel exhaust exposure and chronic pressure overload on cardiac hypertrophy. Transverse aortic banding (26 gauge needle) was done in conjunction with DE (300 μg/m3, non-ozone treated) or FA exposure for 3 months (6 hr/day, 5 days/week). A. Ventricular weight to body weight ratio (VW/BW). B. Left ventricular wall thickness (LV WT). C. Left ventricular end diastolic dimension (LVEDD). D. Left ventricular ejection fraction (LVEF). FA/sham: n = 4; FA/banding: n = 2; DE/sham: n = 4; DE/banding: n = 3. FA: filtered air. DE: diesel exhaust.
