[Scales of risk assessment in coronary surgery and their usefulness].
Currently, there is an increasing interest in the fields of cardiology and cardiac surgery related to systems of risk assessment of cardiac surgery procedures. The main benefit of these systems is quality control of results obtained. Nevertheless, there are other interesting implications. Currently, most of the available scales make estimations of mortality risk with a defined operative technique, using preoperative variables. Other systems can make predictions on postoperative length of stay. Scales are built using the results of a large series, processed with different mathematical models. An important condition is the simplicity of use. There is a wide range of available systems originating from clinical experience in Europe and North-America. All of them include a common number of predictive factors, although the assigned weight can vary significantly. We recommend the routine use of these scales as a quality control system and as a method of characterization of our populations in order to make adequate comparisons among different groups.
