The present invention relates to a method for identifying a subject at risk of developing heart failure, comprising: (a) determining the level of one or more biological markers in a biological sample of said subject; (b) comparing the level of said biological marker to a standard level of the same biological marker; and (C) determining whether the level of the marker is indicative of a risk for developing heart failure, wherein the biological marker is Krüppel Like Factor 15 (KLF-15) and/or lysosomal integral membrane protein-2 (LIMP-2) and/or fragments and/or variants thereof, and/or wherein the biological marker is a gene coding for KLF15 and/or LIMP-2, and/or fragments and/or variants thereof. The invention further relates to use of the KLF15 and/or LIMP-2 protein, and/or the gene coding for KLF15 and/or LIMP2, and/or fragments, and/or variants of said genes and/or proteins, for the preparation of a medicament for a prophylactic and/or a therapeutic medicament for prevention and/or treatment of heart failure.
