Aortic Compliance

Abbreviation

Pronunciation

/eɪˈɔrtɪk kəmˈplaɪəns/

A decrease in aortic compliance increases cardiac and vascular load and leads to increase in systolic pressure and pulse pressure, an independent risk factor for development of cardiovascular disease.
Noninvasive Doppler Ultrasound Assessments of Aortic Compliance(AC) in Hypertension Patients
With recent reports suggesting that arterial wall compliance is improved by drugs acting on vascular structure or endothelial cell or smooth muscle function, estimation of central aortic compliance in clinical settings may become more relevant.
Objective To explore clinical value of noninvasive Doppler ultrasound assessments of aortic compliance in type 2 diabetes mellitus and to evaluate influence of plasma glucose and lipoproteins on it.
Recently, aortic compliance in humans has been studied using two-dimensional and transesophageal echocardiography and invasive intravascular ultrasound, but noninvasive evaluation of aortic compliance with Doppler-derived pulse wave velocity ( PWV ) is rarely reported.
