Troponin levels in patients with stable CAD

Slightly elevated serum troponin T levels are common in patients with stable coronary artery disease (CAD). We observed a significant correlation between the level of troponin and the presence of atherosclerotic damage to the coronary arteries. A significant correlation between the value of troponin and the extent of atherosclerotic damage (in terms of the number of damaged arteries) could not be demonstrated. On the basis of our findings, the absolute level of troponin T in patients with stable CAD must be interpreted with caution, especially in patients who also have renal insufficiency. Determination of basal troponin T levels in patients with stable CAD is reasonable as they may be used for comparison in case of change in a patient's clinical condition.
