Changes in immediate outcome of percutaneous transluminal coronary angioplasty in multivessel coronary artery disease in 1990 to 1991 versus 1994 to 1995.

Coronary angioplasty has undergone major technical changes since the period of inclusion in the randomized trials, comparing it with surgery, particularly with the increased use of coronary stents. This study shows improved in-hospital outcome in terms of primary success and complication rates in patients treated with coronary angioplasty for multivessel disease from 1994 to 1995, compared with the 1990 to 1991 period.
