The authors evaluated the occurrence of risk factors, mode of therapy and in-patient mortality in 726 patients admitted to 38 Czech and Moravian hospitals for unstable angina pectoris with ECG finding of ischaemia without ST segment elevation, who were indicated to application of anticoagulant treatment with low molecular weight heparin. The duration of the before-hospital phase represented a significant risk factor for the progression of disease up to Q myocardial infarction. The relapse of stenocardia occurred in 19.8 % of patients during the hospitalization and myocardical infarction Q occurred in 7.5 % patients, while 2.89 % patients died during hospitalization. These results were compared with those performed in the registries of GRACE, ENACT and Euro Heart Survey Acute Coronary Syndrome - EHS - ACS. The results of therapy in the Czech Republic may be further improved by a more advanced health education within the framework of secondary prevention of IHD, a risk stratification of patients, more modern drug therapy and a better collaboration of hospitals lacking invasive catchment area workplaces of intervention cardiology.
