Abstract
BACKGROUND
The prevalence of long diffuse coronary artery disease (CAD) is increasing nowadays due to increase prevalence of multiple risk factors and population ageing. We aimed in our study to show the differences clinically or angiographically (guided by IVUS) between the use of single long stent versus overlapping stents in very long coronary lesions (≥40 mm) in patients presented with chronic coronary syndromes.
METHODS
550 patients presenting with chronic coronary syndromes were included: 320 treated with a single long stent (≥40 mm) and 230 patients with two or more overlapping stents. Angiographic follow-up (guided by IVUS) 6 months after PCI was performed only in 50 patients. We assessed the procedural characteristics and the occurrence of major adverse cardiovascular events (MACE) after a median follow-up of 24 months.
RESULTS
Total stent length was 56.16 ± 14.85 mm and mean diameter was 3.05 ± 0.36 mm. At the end of follow-up, MACE rate in the single long stent group was 4.1% vs. 7.8% in the overlapping stents group, with higher incidence in overlapping stents group but non-statistically significant (p value = 0.059). PCI using overlapping stents consumed more contrast volume (248 ± 85.36 vs 164.5 ± 70.43 ml, p < 0.001), and higher fluoroscopy time (23.65 ± 9.19 vs 19.72 ± 9.19 min, p < 0.001). Regarding IVUS subgroup follow-up, there was no significant difference between both groups regarding in-stent restenosis and MACE.
CONCLUSIONS
We can conclude that long or overlapping stents are both acceptable therapeutic choices for patients with long CAD. There was no difference between both strategies regarding angiographic follow-up guided by IVUS after 6 months.
