Patients with unstable angina pectoris or non Q-infarction of the myocardium are a very heterogeneous group. It comprises patients with angina pectoris which developed for the first time in their life and had only an episodic character, as well as patients with a severe clinical course and prognostically serious coronary finding. In this connection risk stratification of patients is useful as a provision from which the further diagnostic and therapeutic procedure develops. Based on an analysis of anamnestic data, physical examination, electrocardiogram and examination of cardiospecific, biochemical markers we can divide the patients into groups with a high, medium and low risk. In patients with a high risk the authors use in addition to standard medicamentous treatment also an early invasive examination with possible revascularization. Coronary angiography without the necessity of immediate implementation is also indicated in the majority of patients with medium risk. Conversely low risk patients do not require hospital admission in some cases, or they may be discharged soon.
