ASSESSMENT OF CORONARY ATHEROSCLEROSIS PROGRESSION IN PATIENTS WITH FIVE YEAR HISTORY OF MYOCARDIAL INFARCTION DEPENDING ON THE STATIN THERAPY COMPLIANCE

Abstract

Aim. To study the coronary atherosclerosis progression in patients with 5-year history of myocardial infarction (MI) depending on the statin therapy compliance. Material and methods. Patients (n=31) with a five year history of MI were involved into the study. Patients were divided into two groups depending on the statin therapy compliance during 5 years after MI: group 1 — patients with high compliance, group 2 — patients with low compliance. Assessment of the coronary angiography and lipid profile was performed first time in 2005–2006 during hospital treatment for MI and after 5 years again. Results. Increase in the proportion of patients with two and three coronary vessel disease was found after 5 years of observation, despite the high rate of percutaneous coronary intervention (77.4%) and hypolipidemic therapy. Hemodynamically significant restenosis was found in 11.8% (group 1) and 21.4% (group 2) of patients. Target total cholesterol level was reached only in 42.9% and 11.8% of patients in group 1 and 2, respectively. The target level of low density cholesterol was achieved in no one patient. Conclusion. The findings suggest that in patients with 5-year history of MI coronary atherosclerosis progresses regardless of the statin therapy compliance.
