Abstract

Abdominal aortic aneurysm (AAA) is an important cardiovascular (CV)-related disease that requires surgical treatment to prevent rupture. The elevation of arterial stiffness (AS) is an increasingly recognized independent determinant of CV morbidity and mortality and plays a special role in atherosclerosis. The importance of the surgical technique used for AAA repair in the long-term outcomes still needs to be clarified, and whether endovascular aortic repair (EVAR) or open surgical repair (OSR) confers high AS measurements and thus worse prognosis in terms of CV morbidity needs further investigation. A prospective nonrandomized study that included consecutive patients requiring either EVAR or OSR for AAA disease between February 2015 and January 2016 was conducted. This study is registered on the National Institutes of Health website (ClinicalTrials.gov) and identified with NCT02642952. Several noninvasive measurements of AS and central aortic hemodynamics were obtained before surgery and in the first postoperative control (4-6 weeks), with change from baseline in heart rate-adjusted augmentation index (AIx@75) as main outcome. Likewise, inflammatory circulating biomarkers were also measured in the same time line. We included 44...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Biomarkers for Cardiovascular Risk Assessment

Sensitive and accurate biomarkers used in cardiovascular risk prediction can potentially be used to manage the risk of cardiovascular disease.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
