Protective Role of Diabetes Mellitus on Abdominal Aortic Aneurysm Pathogenesis: myth or reality?

Protective Role of Diabetes Mellitus on Abdominal Aortic Aneurysm Pathogenesis: myth or reality? Curr Vasc Pharmacol. 2015 May 29; Authors: Radak D, Tanaskovic S, Katsiki N, Isenovic ER Abstract An inverse association between diabetes mellitus (DM) and abdominal aortic aneurysm (AAA) risk have been reported. Apart from a lower AAA prevalence among patients with vs without DM, there are data showing that DM may exert a protective role on aneurysmal growth in patients with small AAAs, thus decreasing the risk of rupture. As atherosclerosis has almost the same risk factors as aneurysms, the decreased AAA prevalence in patients with DM may indicate that atherosclerosis is an associated feature and not a cause of the aneurysms. Alternatively, DM may be associated with factors that influence AAA formation. In this narrative review, we discuss the inverse association between DM and AAA. We also comment on underlying cellular and genetic pathophysiological mechanisms of DM, AAA and atherosclerosis. The effects of drugs, commonly prescribed in DM patients, on AAA development and growth are also considered. PMID: 26022380 [PubMed - as supplied by publisher]

CONCLUSIONS: Pharmacological inhibition of SGLT-2 by empagliflozin inhibits AAA formation. SGLT-2 inhibition might represent a novel promising therapeutic strategy to prevent AAA progression ( Visual Overview ). PMID: 31294626 [PubMed - as supplied by publisher]

Even though diabetes mellitus is a major risk for cardiovascular events and atherosclerosis-related diseases, it is negatively associated with abdominal aortic aneurysm. The understanding of the mechanisms underlying this negative association could bring new insights to identify prognostic and therapeutic targets. Here we summarize current knowledge of the relationship between glycemic parameters and clinical outcomes of patients with abdominal aortic aneurysm. Translational applications of glucose-targeted approaches as well as their potential interest for clinical practice are discussed in this context.

Authors: Wierzba W, Pinkas J, Karnafel W, Dziemidok P, Jawień A, Śliwczynski A Abstract Introduction: There are reports that diabetes mellitus reduces the risk of aortic aneurysms and many reports that diabetes mellitus reduces the risk of abdominal aortic aneurysms. In earlier years there were also studies that did not demonstrate any effects of diabetes on the rate of aortic aneurysms. Material and methods: For the year 2012, between 1 January and 31 December, reports for services regarding treatment for aortic aneurysms were found. At the same time, the reports for services associated with diabetes with th...

Epidemiologic data indicate decreased risk for development, growth, and rupture of abdominal aortic aneurysm (AAA) among patients with type 2 diabetes mellitus (DM). We therefore evaluated mortality and cardiovascular morbidity after acute repair of AAA in diabetic and nondiabetic patients.

Epidemiological data indicate decreased risk for development and growth of abdominal aortic aneurysm (AAA) among patients with diabetes mellitus (DM), but DM also goes with increased cardiovascular (CV) morbidity and mortality. We evaluated effects of DM on mortality and CV morbidity after elective open AAA repair.

A 74-year-old man (height 168 cm; weight 74 kg) with a history of diabetes mellitus and hypertension presented with lower abdominal pain of 4 weeks ’ duration. He had undergone off-pump coronary artery bypass grafting surgery 2 months before the current admission. A computed tomography scan of the abdomen revealed a large infrarenal abdominal aortic aneurysm (diameter 6.4 cm). The patient was scheduled for abdominal aortic aneurysm repair. Af ter placing a right radial arterial catheter under local anesthesia, anesthesia was induced with intravenous midazolam, etomidate, fentanyl, and rocuronium.

Abstract Abdominal aortic aneurysm (AAA) is a local dilatation of the abdominal aortic vessel wall and is among the most challenging cardiovascular diseases as without urgent surgical intervention, ruptured AAA has a mortality rate of>80%. Most patients present acutely after aneurysm rupture or dissection from a previously asymptomatic condition and are managed by either surgery or endovascular repair. Patients usually are old and have other concurrent diseases and conditions, such as diabetes mellitus, obesity, and hypercholesterolemia making surgical intervention more difficult. Collectively, these issues hav...

Abstract Cardiometabolic and vascular disease, with their associated secondary complications, are the leading cause of morbidity and mortality in Western society. Chronic inflammation is a common theme that underlies initiation and progression of cardiovascular disease. In this regard, monocytes/macrophages are key players in the development of a chronic inflammatory state. Over the past decade, epigenetic modifications, such as DNA methylation and posttranslational histone processing, have emerged as important regulators of immune cell phenotypes. Accumulating studies reveal the importance of epigenetic enzymes i...

Conclusion: Our literature review provides strong (but often circumstantial) evidence that diabetic patients exhibit slower growth of aortic aneurysms and a lower rate of aortic dissection. Furthermore, clinical and experimental studies indicate that common antidiabetic medications on their own inhibit growth of aortic aneurysms. These findings indicate a paradoxically beneficial effect of the otherwise highly detrimental diabetic state.Cardiology 2018;141:107 –122
