| Homocysteine |
Studies in recent years have determined that a moderately elevated homocysteine level in serum or plasma is a strong and independent risk factor for occlusive arterial disease and venous thrombosis, and also predicts vascular and all-cause mortality. High homocysteine levels are found in as many as 50% of patients with stroke and other atherothrombotic diseases. |

| Ischemia Modified Albumin |
Ischemia Modified Albumin (IMA) is a sensitive and early biochemical marker of ischemia. IMA is produced when circulating albumin comes in contact with ischemic tissue in the heart. IMA concentrations in blood rise quickly and remain elevated during an ischemic event, returning to normal level several hours after cessation of ischemia. IMA can be used in conjunction with electrocardiogram (ECG) and troponin as an aid in ruling out acute coronary syndrome (ACS) at presentation. |

| Lipoprotein (a) |
An independent risk factor for heart disease, LP(a) is often used along with other biomarkers to screen selectively for risk factors for coronary artery disease and cerebral vascular disease. Patients with a high level of Lp(a), which is thought to be genetically determined and not easily modified, may benefit from more aggressive treatment of other risk factors. |
