    Journal: Ann Vasc Surg; 2022 Oct; 86():320-327. PubMed ID: 35483617.
    Abstract:
    BACKGROUND: The objective of this population-based study was to analyze short- and long-term major adverse cardiovascular events (MACE) after endovascular repair of ruptured or nonruptured thoracic (TAA) and abdominal aortic aneurysms (AAA). METHODS: Nationwide retrospective registry study including all patients who underwent endovascular repair (thoracic endovascular aortic repair, TEVAR; abdominal endovascular aneurysm repair, EVAR) for nonruptured/intact (iAAA/iTAA) or ruptured (rAAA/rTAA) abdominal or thoracic aneurysms between 2000 and 2018. The primary outcome was a composite of cardiovascular death, stroke, or myocardial infarction (MACE). RESULTS: There were 8,641 patients with TAA and AAA; 634 TEVAR procedures [iTAA 488; rTAA 146], and 8007 EVAR procedures [iAAA 7071; rAAA 936] were performed. MACE incidence at 90-day after TEVAR for iTAA was 10.2% and for rTAA 26.7% [HR 3.02, 95% CI 1.99-4.6]; MACE at 90-day after EVAR for iAAA was 3.7% and for rAAA 26.9% [HR 8.5, 95% CI: 7.16-10.11]. There was a higher cumulative incidence of MACE at 90-day after TEVAR for iTAA compared to EVAR for iAAA [HR 2.82, 95% CI 2.09-3.82] but no difference between the procedures after ruptured aneurysm repair. The median follow-up time was 3.28 years [IQR 1.31-5.94]. There was no long-term difference in MACE between EVAR and TEVAR after ruptured [90 days-5 years: HR 1.14, 95% CI 0.76-1.71; 5-10 years: HR 0.78, 95% CI 0.31-1.96] or intact [90 days-5 years: HR 1.19, 95% CI 0.97-1.46; 5-10 years: HR 0.82, 95% CI 0.56-1.21] aneurysm repair. Female gender had higher long-term incidence of MACE after intact [HR 1.14, 95% CI 1.03-1.27] and ruptured [HR 1.36, 95% CI 1.12-1.65] endovascular aortic aneurysm treatment. After intact aneurysms repair; age [HR 1.05, 95% CI 1.04-1.05], history of angina pectoris [HR 1.19, 95% CI 1.08-1.32], heart failure [HR 1.90, 95% CI 1.69-2.13], and stroke [HR 1.33, 95% CI 1.15-1.53] were associated with MACE. CONCLUSIONS: This nationwide cohort study still demonstrated a high risk of early and late cardiovascular events after endovascular aortic repair. Comprehensive strategies for postoperative cardiovascular disease prevention may be needed here.
