A Multivariate Analysis of a Modified Frailty Index on Perioperative Morbidity and Mortality Following Non-Emergent Endovascular Aortic Aneurysm Repair.
Ann Vasc Surg

Division of Vascular Surgery, University of South Florida College of Medicine, Tampa, Florida, USA. Electronic address:
Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

Mitochondria dysfunction plays a central role in the development of vascular diseases as oxidative stress promotes alterations in mitochondrial morphology and function that contribute to disease progression. Redox imbalances can affect normal cellular processes including mitochondrial biogenesis, electrochemical equilibrium, and the regulation of mitochondrial DNA. In this review, we will discuss these imbalances and, in particular, the potential role of mitochondrial fusion, fission, biogenesis, and mitophagy in the context of vascular diseases and how the dysregulation of normal function might contribute to disease progression.

: Left ventricular aneurysm (LVA) causes geometric changes, including reduced systolic function and a more spherical shape, which is quantified by the sphericity index (SI), the ratio of the short to long axis in the apical four-chamber view. This study aimed to assess SI's value in A-LVA and B-LVA, identify influencing factors, and evaluate its clinical relevance. : This clinical study included 54 patients with post-infarction LVA and used echocardiography to determine LVA locations (A-LVA near the apex and B-LVA in the basal segments), with SI and other echocardiographic measures assessed in both systole and diastole for the entire cohort and stratified by A-LVA and B-LVA groups.

Department of vascular surgery, the Second Affiliated Hospital of Nanchang University, No. 1 Minde Road, Nanchang, Jiangxi, China, 330006.
Objective: To assess the impact of lipid-lowering drugs (LLDs) and antihypertensive drugs on the risk of aortic diseases.
Methods: Mendelian randomization was utilized to analyze data from 500,000 participants in the UK Biobank to evaluate the effects of statins, PCSK9 inhibitors (PCSK9i), beta-blockers, and calcium channel blockers on the risks of thoracic aortic aneurysm (TAA), abdominal aortic aneurysm (AAA), and aortic dissection (AD) using genetic variants as proxies. Real-world pharmacovigilance data from the FAERS database was used.
