SAN DIEGO--(BUSINESS WIRE)--Critical Diagnostics today announced publication in the latest issue of the Journal of Heart Failure results of a study involving 995 patients who presented to the emergency room (ER) with chest pain. The study concluded that in this undifferentiated, symptomatic patient population ST2 was more specific for acute heart failure than BNP and that ST2 is independently predictive of future death and/or heart failure and has incremental utility in combination with BNP.
