[Current prognosis of unstable angina. The results of clinical studies].
In the last decade there has been a change in the clinical evolution of patients with unstable angina. A better knowledge of his pathophysiology has improved the progress in their treatment and prognosis. Aspirin and heparin have played an important role in this change. Nowadays, the rates of death and acute myocardial infarction at 6 weeks are about 2% and 5% respectively. Nevertheless, the debate about the stratification risk and the best therapeutic options persist. Part of this debate corresponds to the classification differences and to the heterogeneity of variables considered to be end points. On the other hand, the clinical importance conferred to variables identified as predictor of worse prognosis is not valued enough, forgetting that the low prevalence of events results in a low positive predictive value.
