[CHANGES OF GLOBAL AND LOCAL MYOCARDIAL CONTRACTILITY OF CHERNOBYL ACCIDENT CLEAN-UP WORKERS WITH STABLE ANGINA].

Changes of global and local myocardial contractility of Chernobyl accident clean-up workers (ChA CW) with stable angina were investigated. There were discovered that regular long-term treatment of ChA CW with stable angina using of antiischemic and metabolic drugs promoted to stabilization of global and local myocardial contractility indexes. Ejection fraction, degree of contraction of front-rear systolic left ventricle size, systolic thickness of interventricular septum sufficiently increased. Step-by-step worsening of global and local myocardial contractility indexes in cases of non-regular treatment was taken place. Sufficient differences between indexes of ejection fraction, left ventricle end-diastolic volume, systolic thickness and excursion of interventricular septum in stable angina patients of general population and ChA CW were discovered. Results of global and local myocardial contractility monitoring in ChA CW with stable angina substantiate the advisability of long-term supporting treatment using evidence-based drugs.
