Biochemical markers in heart failure

SummaryIn industrialized countries, chronic heart failure (HF) is a major illness and cause of death. However, because of the paucity of specific clinical manifestations of HF, its early diagnosis and management might be challenging. Therefore, biochemical markers of HF are now being closely scrutinized. An ideal biochemical marker should be a prognostic indicator, should assist in the early diagnosis, reflect the therapeutic response, and help grading the risk associated with each stage of HF. This review summarizes our current understanding of biochemical markers of HF.
