A series of 149 consecutive patients admitted for myocardial infarction (ex
cluding cardiogenic shock), dilated and systematically stented in the acute
phase before the 12th hour and followed up for a period from 30 days to 2
years, was studied.
The criteria of follow-up were : number of asymptomatic patients, deaths, r
einfarction, residual ischaemia. cardiac failure, angioplasty or bypass sur
gery. On admission. 40.9% of the infarcts were anterior, 44.3% inferior and
14.8% lateral. One hundred and eighty-three stents with a diameter of over
3mm were inserted.
The angioplasty success rate was 98.6%. During the hospital period. 90.6% o
f patients were asymptomatic. 4.7% had recurrent infarction. 4% had cardiac
failure. 0.7% had residual ischaemia. and there were 0.7% of cardiac death
s. The survival rate was 97.2% at 2 years : 69.8% of patients were totally
asymptomatic: the cumulative major cardiac event rate (death, reinfarction.
angioplasties or bypass graft) was 25.9% and the reoperation rate on the c
ulprit vessel was 20.1%.
These results show the short acid long-term value of angioplasty associated
with coronary stenting over other techniques in the acute phase of infarct
ion based on the criteria studied. The long-term results of larger randomis
ed studies using glycoprotein inhibitors (Gp IIb IIIa) associated with angi
oplasty and stenting are expected for validating the use of these products.
