Background ST-segment-elevation myocardial infarction is associated with an intense acute inflammatory response and risk of heart failure.

Methods and Results We conducted a randomized, placebo-controlled, double-blind, clinical trial in 99 patients with ST-segment-elevation myocardial infarction in which patients were assigned to 2 weeks treatment with anakinra once daily (N=33), anakinra twice daily (N=31), or placebo (N=35). hsCRP area under the curve was significantly lower in patients receiving anakinra versus placebo (median, 67 [interquartile range, 39-120] versus 214 [interquartile range, 131-394] mg·day/L; P<0.001), without significant differences between the anakinra arms. No significant differences were found between anakinra and placebo groups in the interval changes in left ventricular end-systolic volume (median, 1.4 [interquartile range, -9.8 to 9.8] versus -3.9 [interquartile range, -15.4 to 1.4] mL; P=0.21) or left ventricular ejection fraction (median, 3.9% [interquartile range, -1.6% to 10.2%] versus 2.7% [interquartile range, -1.8% to 9.3%]; P=0.61) at 12 months. The incidence of death or new-onset heart failure or of death and hospitalization for heart failure was significantly lower with anakinra versus placebo (9.4% versus 25.7% [P=0.046] and 0% versus 11.4% [P=0.011], respectively), without difference between the anakinra arms.

Abstract
Background ST-segment-elevation myocardial infarction is associated with an intense acute inflammatory response and risk of heart failure. We tested whether interleukin-1 blockade with anakinra significantly reduced the area under the curve for hsCRP (high sensitivity C-reactive protein) levels during the first 14 days in patients with ST-segment-elevation myocardial infarction (VCUART3 [Virginia Commonwealth University Anakinra Remodeling Trial 3]). Methods and Results We conducted a randomized, placebo-controlled, double-blind, clinical trial in 99 patients with ST-segment-elevation myocardial infarction in which patients were assigned to 2 weeks treatment with anakinra once daily (N=33), anakinra twice daily (N=31), or placebo (N=35). hsCRP area under the curve was significantly lower in patients receiving anakinra versus placebo (median, 67 [interquartile range, 39-120] versus 214 [interquartile range, 131-394] mg·day/L; P<0.001), without significant differences between the anakinra arms. No significant differences were found between anakinra and placebo groups in the interval changes in left ventricular end-systolic volume (median, 1.4 [interquartile range, -9.8 to 9.8] versus -3.9 [interquartile range, -15.4 to 1.4] mL; P=0.21) or left ventricular ejection fraction (median, 3.9% [interquartile range, -1.6% to 10.2%] versus 2.7% [interquartile range, -1.8% to 9.3%]; P=0.61) at 12 months. The incidence of death or new-onset heart failure or of death and hospitalization for heart failure was significantly lower with anakinra versus placebo (9.4% versus 25.7% [P=0.046] and 0% versus 11.4% [P=0.011], respectively), without difference between the anakinra arms.
