The difference in aortic root sizes is probably related to the different measuring tools used, echo versus CT. When there is a difference between the two, CT is often preferred as its measurements are orthogonal to axis of the vessel being measured. Adjusted changes from baseline and between treatment differences in mean cfPWV in patients with hypertension randomized to telmisartan ( ) or valsartan ( ) for 12 weeks. Adjusted between treatment difference (telmisartan-valsartan). Telmisartan vs. Valsartan in Patients With Mild to Moderate Hypertension Following a Missed Dose The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. the difference between the drugs is subtle. They both belong to the ARB family. Losartan is the more popular drug for aortic therapy because that is the drug that some researchers have chosen to pursue for clinical studies.
