Hyperlipoproteinemia (acc. to Fredrickson's classification) in patients with myocardial infarction and imminent infarction.

Abstract

In 500 cases (379 men and 121 women) of ischemic heart disease, including 428 patients with myocardial infarction and 72 -- with imminent infarction, blood lipid levels were determined. Blood samples were taken on fasting, by the end of hospitalization, from patients with myocardial infarction on the 18th-21st day of disease, and from those with imminent infarction after cessation of pain. In 152 patients (30.4%), including 87 with infarction and 65 with imminent infarction, disturbances in the blood lipid pattern were found and classified according to Fredrickson. When expressed as percentage against the material of 152 patients with blood lipid disturbances, type II A was found in 103 cases (67.8%), type II B -- in 25 cases (16.4%), and type IV -- in 24 cases (15.8%). When calculated against the whole material of 500 patients, type II A accounted for 20.6%, type II B -- for 5%, and type IV -- 4.8% of cases.
