Abstract


OBJECTIVES
Hyperlipidemia is an important risk factor of coronary atherosclerosis. Serum lipids, especially cholesterol level is closely related to coronary artery and early identification and treatment of hypercholesterolemia reduced the risk of ischemic heart disease. In secondary prevention studies, lipid regulation has been demonstrated to result in a reduced incidence of myocardial infarction and mortality. But during the acute phase of a myocardial infarction, the serum lipid pattern is known to be rapidly changed and consequently dose not reflect the baseline level of the patient. Total serum cholesterol concentrations measured within 24 hours after acute myocardial infarction are likely to reflect basal levels, thus they must be used as the reference for the diagnosis and treatment of hyperlipidemia. If serum lipid levels were not measured within 24 hours of acute chest pain, it is essential to correct the lipid level to the baseline level. So we investigated the following. First, serum lipid alteration during the acute phase of acute myocardial infarction, second, the factors that are related to lipid change, third, the time to check the baseline value of lipid level during the acute phase of myocardial infarction.
METHODS
We have measured the total cholesterol, LDL cholesterol, HDL cholesterol and triglyceride at admission time and the next day in a group of 51 acute myocardial infarction patients who had acute chest pain.
RESULTS
First, total cholesterol, LDL cholesterol at the next day were significantly reduced. Second, positive correlation was noted between lipid alteration and the lipid level that was checked at admission time. Last, male groups had more significant reduction of LDL cholesterol than female groups.
CONCLUSION
Cholesterol levels thats were checked the next day were significantly reduced in comparison with the cholesterol value registered at hopital admission. Consequently, it is essential to check the lipid level at the time of hospital admission. But if it was not done, corrected values are a useful guide to patients basal lipid state and treatment references.
