Lecithin:cholesterol acyltransferase as a possible diagnostic tool in ischemic heart disease. 1978

M Dobiásová, and K Vondra

Basal values of lecithin:cholesterol acyltransferase (LCAT) were estimated in healthy subjects, in patients with the so-called risk ischemic heart diseases (IHD)--obesity, diabetes, hypertension, and hyperlipoproteinemia II--and in patients with a IHD-infarction of the myocardium. A precise method employing a 14C-4-cholesterol-labeled common normolipidemic substrate was used. A highly significant difference in the average values of LCAT activity between healthy men and women was found. LCAT in men with 'risk' diseases decreased, while in women it remained at the level of the reference group. To assess the dependence between LCAT-dependent indicators and IHD, criteria for evaluating the deviations from reference values were proposed. The number of deviations from the reference group increased in the sequence: obesity, hypertension, diabetes, hyperlipoproteinemia, and the infarction of the myocardium.

UI MeSH Term Description Entries
D006949 Hyperlipidemias Conditions with excess LIPIDS in the blood. Hyperlipemia,Hyperlipidemia,Lipemia,Lipidemia,Hyperlipemias,Lipemias,Lipidemias
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D007862 Phosphatidylcholine-Sterol O-Acyltransferase An enzyme secreted from the liver into the plasma of many mammalian species. It catalyzes the esterification of the hydroxyl group of lipoprotein cholesterol by the transfer of a fatty acid from the C-2 position of lecithin. In familial lecithin:cholesterol acyltransferase deficiency disease, the absence of the enzyme results in an excess of unesterified cholesterol in plasma. Lecithin Cholesterol Acyltransferase,Cholesterol Ester Lysolecithin Acyltransferase,Lecithin Acyltransferase,Phosophatidylcholine-Sterol Acyltransferase,Acyltransferase, Lecithin,Acyltransferase, Lecithin Cholesterol,Acyltransferase, Phosophatidylcholine-Sterol,Cholesterol Acyltransferase, Lecithin,O-Acyltransferase, Phosphatidylcholine-Sterol,Phosophatidylcholine Sterol Acyltransferase,Phosphatidylcholine Sterol O Acyltransferase
D008055 Lipids A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant & Hackh's Chemical Dictionary, 5th ed) Lipid
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009765 Obesity A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

D003920 Diabetes Mellitus A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.
D005260 Female Females
