Implication
PTCA was associated with high success but frequent repeat revascularization; leaves open optimal strategy versus medical therapy in unstable angina.
Structured PICO
What are the procedural success rates and 1-year clinical outcomes of PTCA in patients with unstable angina and non-Q-wave myocardial infarction?
P
Population
444 patients with either unstable angina pectoris or non-Q-wave myocardial infarction (NQWMI) who underwent percutaneous transluminal coronary angioplasty (PTCA) before hospital discharge (enrolled in the TIMI IIIB Investigation).
I
Intervention
Percutaneous transluminal coronary angioplasty (PTCA)
O
Outcome
Angiographic success, cumulative incidence of death and infarction at 1 year, periprocedural complications, and repeat revascularization at 1 yearhard clinical
PTCA in patients with unstable angina and non-Q-wave myocardial infarction is associated with high angiographic success and low initial complications, though repeat revascularization at 1 year is common and routine thrombolysis pretreatment does not improve outcomes.
