Methods Untreated hypothyroid patients and age-matched euthyroid patients, who underwent 128-slice retrospective electrocardiogram-gated MDCT to evaluate the coronary arteries, were assessed. Intraluminal aortic areas in systolic and diastolic phases of the cardiac cycle were measured with multiphase reformation at predefined locations including the ascending aorta, proximal descending aorta and distal descending aorta in the widest axial plane. Results The study included 21 hypothyroid and 21 euthyroid patients. Patients with hypothyroidism exhibited decreased aortic distensibility between each location in the thoracic aorta (ascending aorta, proximal descending aorta and distal descending aorta) compared with euthryoid patients. Conclusions Hypothyroidism was associated with preclinical vascular alteration, characterized by impaired aortic distensibility at each location of the thoracic aorta, which has been shown to be related to increased cardiovascular risk. Monitoring of aortic distensibility is relevant for evaluating coronary artery disease progression and treatment choices.eninfo:eu-repo/semantics/openAccessResearch & experimental medicinePharmacology & pharmacyAortic distensibilityCoronary artery diseaseHypothyroidismMultiple row detector computed tomographyMDCTFlow velocity reserveCommon carotid-arteryFatty liver-disasePulse-wave velocitySubclinical hypothyroidismThyroxine treatmentYoung-adultsStiffnessAtherosclerosisRiskAortic distensibilityCoronary artery diseaseHypothyroidismMultiple row detector computed tomographyAortaAorta, thoracicCase-control studiesCoronary angiographyDisease progressionFemaleHumansHypothyroidismMiddle agedRetrospective studiesRisk factorsSeverity of illness indexTomography, x-ray computedVascular stiffnessArticle0003252737000322-s2.0-848872862941691169841524026774Medicine, research & experimentalPharmacology & pharmacyHypothyroidism; Thyrotropin; Thyroid FunctionLiothyronineLow density lipoproteinThyrotropinThyroxineAdultAngiocardiographyArtery complianceArticleAscending aortaAtherosclerosisCardiac gated imagingCardiovascular riskCholesterol blood levelClinical articleComputed tomography scannerControlled studyCoronary artery diseaseDescending aortaElectrocardiogram gated multiple row detector computed tomographyElectrocardiographyFemaleHumanHypothyroidismMultidetector computed tomographyThoracic aorta
