[The effect of hypolipemic therapy with diet and simvastatin on the course of angina pectoris and the results of exercise stress test in patients with coronary artery disease].
Statins are the multi-directorial acting drugs in atherosclerosis prevention, which decrease the overall and cardiovascular mortality. The aim of this study was to estimate the effect of six-month long hypolipemic therapy with diet and 20 mg of simvastatin on clinical intensity of angina pectoris and the course of exercise stress test.


METHODS
We studied 44 patients with typical anginal chest pain. In all blood sampling and treadmill stress test were made, and next in all hypolipemic diet and simvastatin 20 mg were recommended. After four weeks and six months of treatment clinical assessment and exercise test were made.


RESULTS
After four weeks and six month long observation period the decrease of total and LDL cholesterol, triglycerides and fibrinogen were found. Moreover, we have observed the improvement in frequency of anginal symptoms, their intensity in CCS classification and number of nitroglycerin tablets taken per week. The course of exercise test was also ameliorated: the percentage of patients, in whom stress test was finished because of chest pain was decreased, time of chest pain duration after exercise cessation was shorter, the percentage of patients with significant ST interval depression diminished, maximal ST interval depression as well as the time of significant ST interval depression duration also decreased. Although improvement in values of mentioned parameters, after six months long therapy with simvastatin the percentage of patients with Duke's treadmill score value showing intermediate cardiovascular risk (between -10 and +4) increased. In conclusion, therapy with hypolipemic diet and simvastatin already after four weeks decreased plasma lipids and fibrinogen levels and improved the course of angina pectoris and exercise stress test, what suggested its effectiveness not only as the treatment improving atherosclerosis risk factors, but also with prompt and clinical important effect ameliorating the handicapped coronary reserve.
