[Percutaneous myocardial revascularization procedures in Brazil in 1996-1997 compared to the 1992-1993 period. A report of the National Registry--National Center for Cardiovascular Interventions (CENIC)].
OBJECTIVE
To report the results of percutaneous coronary interventions, in Brazil, in the years 1996-97, comparing them to those of 1992-93.


METHODS
Data were collected in a standard form and the 1996-97 results were compared to those of 1992-93.


RESULTS
The current Registry received data from 79% effective members of the SBHCI in 127 hospitals, including 22,025 patients, 60.67% of whom underwent PTCA, 36.57% stent implantation, 2.3% PTRA, 0.06% DCA and 0.4% laser angioplasty. Balloon angioplasty was the most frequent procedure in 1996-97, but its overall rate fell from 6.75% to 55.8% (p = 0.0001) concomitantly, there was a 35% relative increase in the use of stents from 1992-93 to 1996-97. The success rate of the later period was higher (89.7% vs 92.8%, p = 0.000001), with lower residual stenosis (22% vs 19%, p = 0.001). Besides, there were lower major complications rates: acute myocardial infarction (2.5% vs 1.2%, p = 0.002) and death (1.8% vs 1.4%, p = 0.0003).


CONCLUSIONS
The procedures most often carried out in both periods were balloon angioplasty (60.67%) and implantation of stents (36.57%); the success rate high, abrupt closure rate was low (1.5%). These favorable results corroborate the high standards of the Brazilian Interventional Cardiology.
