Predictors of angiographic findings when chest pain recurs after successful coronary angioplasty.

The angiographic findings of 569 patients who underwent repeat coronary angiography for recurrence of chest pain after successful coronary angioplasty were evaluated. On the basis of angiographic findings, 250 patients (44%) were classified as having restenosis, 72 (13%) incomplete revascularization, 115 (20%) new significant coronary artery lesions, and 132 (23%) no significant disease. The number of diseased vessels at the time of coronary angioplasty (P < 0.

'Tandem lesion' coronary angioplasty: ten years' experience.

Background: To evaluate the acute and long-term results of 'tandem lesion' coronary angioplasty in the left anterior descending artery, and to identify the determinants of restenosis.

Methods: A retrospective analysis of clinical, angiographic, and procedure-related variables was carried out on a consecutive series of 102 patients (mean age 54 years, range 34-71 years; 77% men) who had undergone tandem lesion coronary angioplasty in the left anterior descending artery (204 lesions) between 1981 and 1991.

Results: Angiographic success was achieved in 96 patients (94%) and 195 lesions (96%).

Percutaneous transluminal coronary angioplasty in patients 70 years of age or older: 12 years' experience.

Objective: To evaluate the short and long term results of coronary angioplasty in patients aged 70 years and older and identify the determinants of long-term survival.

Design: A retrospective analysis of clinical, angiographic, and procedure related variables on a consecutive series of patients.

Patients: 163 patients aged 70 years and older (mean (range) age 73 (70-83) years; 63% men) who underwent a first coronary angioplasty procedure between 1981 and 1993.

Percutaneous transluminal coronary angioplasty of aorta ostial, non-aorta ostial, and branch ostial stenoses: acute and long-term outcome.

The acute and long-term outcome of 198 patients who underwent coronary angioplasty of ostial stenoses was evaluated. Procedural success was achieved in 85% of aorta ostial stenoses, 90% of non-aorta ostial stenoses, and 87% of branch ostial stenoses (P = 0.84).

Efficacy of a third coronary angioplasty for a second restenosis: short-term results, long-term follow up, and correlates of a third restenosis.

Objective: To report on the short-term and long-term results of patients who underwent a third coronary balloon angioplasty for a second restenosis and to identify the correlates of a third clinical restenosis.

Design: A retrospective analysis of clinical, angiographic, and procedure related variables of a consecutive series of patients.

Patients: 62 patients (mean (range) age 53 (31-72) years; 84% men) who underwent a third coronary balloon angioplasty of a single coronary artery segment at which restenosis had occurred after two previous angioplasty procedures between 1986 and 1992.
