A method for identifying one or more markers for a cardiovascular disease or condition comprising: a) preparing a first profile of analytes by detecting said analytes from a subject's phagocytic cells, wherein the subject has said disease or condition; preparing a second profile of said analytes by detecting said analytes from the subject's non-phagocytic cells; identifying a first set of differences between the first and second profiles, wherein the first set of differences is specific to the first profile relative to the second profile; b) preparing a third profile of said analytes by detecting said analytes from a control subject's phagocytic cells, wherein the control subject does not have said disease or condition; preparing a fourth profile of said analytes by detecting said analytes from the control subject's non-phagocytic cells; identifying a second set of differences between the third and fourth profiles, wherein the second set of differences is specific to the third profile relative to the fourth profile; c) identifying one or more analytes specific to the first set of differences relative to the second set of differences, the identified analytes being markers of said disease or condition; d) obtaining a fifth profile of said analytes from cells or tissues affected by said disease or condition in the subject having said disease or condition; obtaining a sixth profile of said analytes from cells or tissues not affected by said disease or condition in the subject having said disease or condition; identifying a third set of differences between the fifth and sixth profiles, wherein the third set of differences is specific to the fifth profile relative to the sixth profile; and e) identifying at least one of the one or more markers of c) present in the third set of differences. a) preparing a first profile of analytes by detecting said analytes from a subject's phagocytic cells, wherein the subject has said disease or condition; preparing a second profile of said analytes by detecting said analytes from the subject's non-phagocytic cells; identifying a first set of differences between the first and second profiles, wherein the first set of differences is specific to the first profile relative to the second profile; b) preparing a third profile of said analytes by detecting said analytes from a control subject's phagocytic cells, wherein the control subject does not have said disease or condition; preparing a fourth profile of said analytes by detecting said analytes from the control subject's non-phagocytic cells; identifying a second set of differences between the third and fourth profiles, wherein the second set of differences is specific to the third profile relative to the fourth profile; c) identifying one or more analytes specific to the first set of differences relative to the second set of differences, the identified analytes being markers of said disease or condition; d) obtaining a fifth profile of said analytes from cells or tissues affected by said disease or condition in the subject having said disease or condition; obtaining a sixth profile of said analytes from cells or tissues not affected by said disease or condition in the subject having said disease or condition; identifying a third set of differences between the fifth and sixth profiles, wherein the third set of differences is specific to the fifth profile relative to the sixth profile; and e) identifying at least one of the one or more markers of c) present in the third set of differences.
