have systemic HT, although there is a lower prevalence of HT among young patients aged <40 years with AD who are more likely to have genetic alterations. 8,9 HT is also associated with the presence and development of aortic aneurysms. 10,11 Therefore, the management of HT is of clinical interest in the primary prevention of AD in adults. Recent research focusing on systolic blood pressure (SBP)lowering therapy since landmark trials in the 1990 s showed the benefits of SBP-lowering therapy on cardiovascular disease in isolated systolic HT in the elderly. 12,13 In contrast, diastolic blood pressure (DBP) is gaining attention in the field of AD. We have previously reported that both SBP and DBP are associated with AD-related deaths in the A ortic disease (AD) comprises a spectrum of potentially devastating conditions, including aortic dissection, aortic aneurysm, and aortic rupture. 1 Despite remarkable diagnostic and therapeutic progress over the past several decades, mortality and morbidity in patients with AD remain high. 1-6 Therefore, it is critical to identify high-risk patients and prevent the development of AD in apparently otherwise healthy individuals during health check-ups.The prevalence of hypertension (HT) is still increasing, and HT is a well-known risk factor for cardiovascular disease, as well as AD. 5,7 According to the International Registry of Aortic Dissection data, the majority of patients
