TNF and Right ventricular dilatation: Our results showed that of the inflammatory markers analyzed (TNFα, IL-1β, IL-6, IL-8, IL10, and IL-12) only IL-8 and IL-12 had higher levels in patients with LVEF of less than 35% Furthermore, patients with the presence of right ventricular dilation on echocardiogram showed elevated IL-6 and IL-8 levels.
