[Dr. Edgardo Schapachnik]

Querido Edgardo: hola como andas? Te envío este mensaje por el pedido de del Dr. Samuel Sclarovski. Yo supongo que se refiere a este artículo 
Bertolasi divide a los pacientes con angina inestable en: un grupo que clasifican como síndrome coronario intermedio que tenía episodios recurrentes de dolor torácico prolongado; otro  con angina progresiva en paciente que ya tenían una angina estable; y un tercer grupo que los denomina post angina de miocardio. 
Espero que le sea de utilidad. Te mando el abstract. Un beso

Abstract
A prospective and randomized study of 142 patients was undertaken to evaluate medical or surgical treatment in patients with unstable angina. The condition of each patient was classified according to one of three categories: intermediate syndrome (44 patients); progressive angina with and wihout previous infarction (53 patients); and postinfarction angina (14 patients). Of the 142 patients, 31 were excluded on the basis of specific criteria. A detailed research protocol, which included early blind random choice of medical or surgical therapy, was followed. The results indicate the following: (1) It is possible to conduct a randomized study of patients with unstable angina, grouped in comparable categories; (2) these groups were statistically homogeneous in relation to the variables examined; (3) in spite of a mean follow-up time of only 8.3 months, the natural history of patients with an intermediate syndrome differed from that of patients with
progressive angina, thus justifying the distinction; (4) patients with an Intermediate syndrome treated surgically appeared to have a significantly reduced mortality rate and those who have survived surgery are in better clinical condition than medically treated patients; and (5) no such differences were found in patients with progressive angina, but a longer follow-up period is warranted.
