Return to work after the infarction is convenient to analyze if these workers could be incorporated from a functional point of view or not at their work, something that, on many occasions, if possible. However, it fails, since, when it comes to the lives of others, the law is much more demanding. For example, where a worker suffers an infarction (ischemic heart disease is the leading cause of death in developed countries), once treated and stabilized what has to be done is measuring its functional capacity through a risk assessment, check if you can return to activity that took place previously, or if it is convenient to change type of work.Such assessment is done through a series of tables that stratify the degree of effort and energy consumption in METS (amount of oxygen that is consumed to make an effort) according to performance on a stress test or stress test. These tables quantify consumption required by each work activity. For example: a job Office has a consumption of two METS, driving a truck means a consumption of between three and four METS, working with a shovel of four kilos are seven METS, etc. Incorporation into work after suffering a heart attack group I, low risk: normally may reinstate in a period of two months for minor or minimal efforts and three months for the intense moderate efforts work.

Group II, medium risk: these patients meet criteria of permanent incapacity to work with third-party responsibility. The rest could continue its work provided that this does not exceed the capacity has been reached with ergometry. Group III, high risk: not should be joining never a job requiring moderate or high effort if it can not provide a solution to your problem and are, therefore, candidates to be assessed for permanent invalidity.
