[Retrospective analysis of a large number of patients over 70 years old, subject to percutaneous coronary angioplasty or to surgery].
BACKGROUND
The number of patients of advanced age with symptomatic coronary illness that need surgical or percutaneous revascularisation is increasing. The aim of the present paper is to gain knowledge of the evolution of patients over 70 years of age subjected to myocardial revascularisation.


METHODS
We compare two groups of patients, in a non-aleatory manner, subjected to angioplasty (N=65) and to surgery (N=75). The average age was 74.12 +/- 3.5 (70-85) and 71.97 +/- 1.9 (70-79) years respectively. The number of unhealthy vessels was greater in the surgical group (1.84 +/- 0.8 vs 2.65 +/- 0.8).


RESULTS
The number revascularised vessels is greater and revascularisation more complete in the surgical group (1.14 +/- 0.4 vs 2.59 +/- 0.9) and (76% vs 49%). There is no difference in mortality in both groups. The functional degree during the evolution is worse for the angioplasty group and besides more antianginous medicines are used in treatment (1.92 +/- 1.2 vs 1.26 +/- 0.8) and they are subjected more frequently to a new revascularisation.


CONCLUSIONS
Both the sick rate and the mortality of the procedure was similar in both groups. Both procedures are valid therapeutic alternatives and are acceptably safe with these patients. Surgery is more complete and is carried out on a group of patients with greater coronary distress. There are no differences in life expectancy amongst the patients treated with either of the techniques. During the follow-up period the functional degree of the surgical group is better and there are more patients treated with monotherapy.
