Prevalence of the Metabolic Syndrome in Patients With Type B Aortic Dissection 

Abstract Background/Objective: The aim of this study is to detect the prevalence of metabolic syndrome (MS) and its components in type B aortic dissection patients. This study assessed the association of MS and its component with type B aortic dissection in Chinese patients. Methods: This cross-sectional prospective observation study consisted of 445 patients who were first diagnosed with type B aortic dissection. Demographic information, clinical symptoms and laboratory parameters were collected using a standard form. Results: Among the 445 TBAD patients 38.4% had MS. Hypertension was present in 78.2% of all TBAD patients. Hypertension, high fasting glucose and obesity were the most common combination of metabolic abnormalities (93%, 79.5% and 63.2%) in the TBAD patients, and a same phenomenon was seen in acute TBAD patients. But among chronic TBAD patients the most frequent individual components were hypertension, hyper- triglyceride and high fasting glucose (92.6%, 75%, and 70.6%). Presence of two or more components of the metabolic syndrome was common: 22.7% had one component, 31.9% had two components, 24.9% had three components, 10.8% had four components and 3.1% had five components. In TBAD, hypertension, obesity, triglycerides and FBG (fasting blood-glucose) were main risk factors for MS.ConclusionThis is the first study provided information on the prevalence and components of MS in the initial TBAD patients. Hypertension, high fasting glucose and obesity were the most common combination of metabolic abnormalities in TBAD patients.
