title: Connective tissue components in normal and atherosclerotic human coronary arteries.
abstract: Human coronary arteries with various degrees of atherosclerosis were analyzed for the concentration of different types of glycosaminoglycans (GAGs). The changes in GAGs were considered against the background of macroscopic atherosclerosis, and the concentration of glycoprotein-bound hexosamines, collagen, calcium and cholesterol. The concentration of calcium was increased and that of hyaluronic acid decreased even in mildly atherosclerotic coronary arteries. The additional changes in advanced atherosclerosis included the increase of collagen and dermatan sulphate and the decrease of heparan sulphate. Cholesterol was increased in mild, and even further in advanced, atheroslcerosis. The concentrations of chondroitin sulphates and glycoprotein-bound hexosamines were not significantly affected by atherosclerosis.
