diabetes and vasoconstriction - Microvascular and metabolic physiology are tightly mcdonald's gestational diabetes linked This Perspective reviews evidence that 1 the relationship between hyperglycemia and microvascular dysfunction MVD is bidirectional and constitutes a vicious cycle 2 MVD in diabetes affects many if not all organs which may play a role in diabetesassociated comorbidities such as depression and cognitive impairment and 3 MVD In patients with diabetes atherosclerosis is the main reason for impaired life expectancy and diabetic nephropathy and retinopathy are the largest contributors to endstage renal disease and blindness respectively An improved therapeutic This resulting state of vasoconstriction has been found in subjects with the metabolic syndrome as well as those with diabetes 20 In this situation the vasculature is in a hyperconstricted state Not only do hypertension and its concomitant complications result from vasoconstrictionbut blood flow is limited to respective tissues Diabetesrelated microvascular disease such as retinopathy and nephropathy are major causes of blindness and Together with the lack of NO glucoseinduced PKC activation causes increased synthesis of ET1 favouring vasoconstriction and platelet aggregation Accumulation of superoxide anion also triggers upregulation of proinflammatory Diabetic vascular diseases molecular mechanisms and therapeutic Diabetes and vascular disease pathophysiology clinical consequences Diabetes mellitus DM is a chronic metabolic disorder characterized by inappropriate hyperglycemia due to lack of or resistance to insulin Lima et al have shown that elevated OGlcNAc levels contribute to endorgan damage and vasoconstriction under diabetes concurrent with decreased eNOS Ser1177 and Akt phosphorylation Ser473 Endothelial Dysfunction and Diabetes Effects on Angiogenesis Vascular Vascular complications of diabetes mechanisms of injury and protective The American Heart Association considers diabetes one of the major controllable risk factors for cardiovascular disease CVD In fact people living with Type apakah penderita diabetes boleh vaksin 2 diabetes are more likely to develop and die from cardiovascular diseases such as heart attacks strokes and heart failure than people who dont have diabetes Why are people with diabetes at increased risk for CVD Vascular Complications of Diabetes and Obesity Type 2 diabetes is associated with the onset of microvascular complications such as nephropathy retinopathy and neuropathy as well as macrovascular complications including coronary artery disease and cerebrovascular disease Litwak et al 2013 Kosiborod et al 2018A study by van Wijngaarden et al 2017 demonstrated that the greater and The Pathophysiology of Cardiovascular Disease and Diabetes Beyond Cardiovascular Disease and Diabetes American Heart Association The high prevalence of coronary and peripheral artery disease in individuals with diabetes mellitus has been recognized for more than a century 7 9 yet the ability to improve cardiovascular event rates by glucose lowering per se has remained elusive In the landmark Framingham Heart Study published in 1979 Kannel and McGee first prospectively demonstrated a higher incidence of Diabetes and Vascular Disease Circulation AHAASA Journals Microvascular Dysfunction and Hyperglycemia A Vicious Cycle With Diabetes mellitus DM and its complications pose a serious threat to human health and have become a global public health issue 12 Over 90 of patients with diabetes have type 2 DM T2DM 34 Clinical Update Cardiovascular Disease in Diabetes Mellitus Circulation Vascular Dysfunction in Diabetes and Obesity Focus on TRP Channels In patients with type 2 diabetes mellitus the vasodilator response to exogenous NO donors is diminished 18 Moreover vasoconstrictor responsiveness to exogenous vasoconstrictors such as endothelin1 is reduced 86 Dysregulation of vascular smooth muscle function is exacerbated by impairments in sympathetic diabetes tipe satu nervous system function 87
