ABSTRACT
BACKGROUND:
Carotid artery intimal medial thickness is a simple, non-invasive and reproducible clinical tool to evaluate atherosclerosis and predict coronary artery disease. Lipoprotein(a) levels are related to both atherogenesis and thrombogenesis and may be a key link between lipid and coronary artery disease. This study evaluated the association of carotid intimal medial thickness and lipoprotein(a) with coronary artery disease. METHODS ANDRESULTS:
We studied 185 randomly selected patients hospitalized for coronary angiogram in our institute. There were 110 angiographically proven patients of coronary artery disease with mean age of 55.8 +/- 9 years (range 34-72 years) and 75 subjects with normal coronary artery anatomy with mean age of 54.8 +/- 8 years (range 34-68 years). The mean carotid intimal medial thickness of subjects with coronary artery disease was significantly higher than in subjects without coronary artery disease (0.84 +/- 0.16 mm v. 0.65 +/- 0.15 mm, p<0.001). The mean carotid intimal medial thicknesses in patients with triple vessel, double vessel and single vessel disease were 0.96 +/- 0.12 mm, 0.84 +/- 0.11 mm and 0.78 +/- 0.13 mm, respectively (p=0.05). The mean lipoprotein(a) of subjects with coronary artery disease was significantly higher than in subjects without coronary artery disease (35.9 +/- 22.3 mg/dl v. 19.1 +/- 21.2 mg/dl, p<0.001). Mean lipoprotein(a) levels in subjects with carotid intimal medial thickness <0.80 was 26.4 +/- 24.2 mg/dl and in subjects with carotid intimal medial thickness > or = 0.80 was 32.1 +/- 22.1 mg/dl (p=0.05).CONCLUSIONS:
There is a strong correlation between carotid and coronary atherosclerosis and carotid intimal medial thickness is a good predictor of presence and extent of coronary artery disease. Lipoprotein(a) level is a powerful independent risk factor for atherosclerosis. Carotid intimal medial thickness and lipoprotein(a) in conjoint can predict coronary artery disease reliably.
