[Late stent-thrombosis-related myocardial infarction].
The objective of the study was to assess the frequency of late stent-thrombosis-related acute myocardial infarction in patients with LAD stents. A series of 930 PCI procedures involving LAD stenting were performed in 920 patients (mean age: 63 years, 667 men) from January 1999 to December 2001. Among those 14 patients had late (> 30 days), thrombosis-related acute myocardial infarction after a mean delay of 135 +/- 131 days. Three-year thrombosis-free survival was 97.6%. By univariate analysis, risk of late thrombosis was associated with LAD-diagonal bifurcation stenting, placement of a stent on the ostium of a diagonal branch and number of stents implanted on the LAD. Patients with these risk factors might be appropriate candidates for long-term combined antiplatelet therapy.
