Local intramural heparin delivery during primary angioplasty for acute myocardial infarction: results of the Local PAMI Pilot Study.
The feasibility and safety of local heparin delivery during acute infarct angioplasty was evaluated in a prospective, multicenter, 120-patient series. Angioplasty was performed using standard techniques, after which heparin (4,000 U) was delivered locally; 25% of patients received stents. Procedural success was reported in 98% of patients; 6.7% of patients suffered death, reinfarction, recurrent ischemia, or stroke during the index hospitalization. The 6-month target vessel revascularization rate was 12.5%. Local heparin therapy with provisional stenting in acute myocardial infarction patients is safe, feasible, associated with a low rate of infarct artery revascularization at 6 months, and may potentially eliminate the need for systemic heparin following the procedure.
