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.

ABSTRACT

RETRACTED ARTICLE: To date, no antiviral therapy has shown proven clinical effectiveness in treating patients with COVID-19. We assessed the efficacy of remdesivir in hospitalized Egyptian patients with COVID-19. Patients were randomly assigned at a 1:1 ratio to receive either remdesivir (200 mg on the first day followed by 100 mg daily for the next 9 days intravenously infused over 30-60 minutes) in addition to standard care or standard care alone. The primary outcomes were the length of hospital stay and mortality rate. The need for mechanical ventilation was assessed as a secondary outcome. Two hundred patients (100 in each group) completed the study and were included in the final analysis. The remdesivir group showed a significantly lower median duration of hospital stay (10 days) than the control group (16 days; P < 0.001). Eleven of the patients in the remdesivir group needed mechanical ventilation compared with eight patients in the control group (P = 0.469). The mortality rate was comparable between the two groups (P = 0.602). Mortality was significantly associated with older age, elevated C-reactive protein levels, elevated D-dimer, and the need for mechanical ventilation (P = 0.039, 0.003, 0.001, and < 0.001 respectively). Remdesivir had a positive influence on length of hospital stay, but it had no mortality benefit in Egyptian patients with COVID-19. Its use, in addition to standard care including dexamethasone, should be considered, particularly in low- and middle-income countries when other effective options are scarce.
