The combined thickness of the intima and media of the carotid artery (carotid intima-medial thickness, CIMT) is associated with cardiovascular disease and stroke.
Analysis of variance showed that the carotid intimal-medial thickness was significantly greater in hypertensive patients with set membership, vertical bar on horizontal stroke 4 alleles compared with set membership, vertical bar on horizontal stroke 2 or set membership, vertical bar on horizontal stroke 3 alleles.
