Cryoglobulins in Coronary-Artery Disease

Abstract

Such substances probably include several groups of proteins, and perhaps other compounds. When present in large amounts, cryoglobulin of itself produces a well defined clinical syndrome similar to Raynaud's disease. Although Rörvik3 stated that even small amounts of cryoglobulin must be considered pathologic, only one clinical study of a disease with small amounts of cold-precipitable substance has been made. That report, by Dreyfuss and Librach,4 suggested that the high incidence of cold-precipitable substance in . . .
