Objective: Vascular abnormality includes two forms, arteriosclerosis (ARS) and atherosclerosis (ATS), which coexist in patients with cardiovascular (CV) diseases. However, whether their combination may lead to a worsening status in those patients remains unclear. We therefore aimed to investigate the association of ARS and/or ATS with hypertensive target organ damage (TOD).
Methods: From June 2014 to August 2015, a total of 1,599 community-dwelling elderly subjects (aged >65 years) from northern Shanghai were recruited. Vascular measurements, such as carotid–femoral pulse wave velocity (cf-PWV), ankle–brachial index (ABI) and carotid plaque, were conducted on each participant, and ARS was defined as cf-PWV >12 m/s, while ATS was defined as participants who have carotid plaque or ABI <0.9. Within the framework of comprehensive CV examinations, CV risk factors were assessed, and asymptomatic TOD was evaluated by measuring participants’ left ventricular mass index (LVMI), peak transmitral pulsed Doppler velocity/early diastolic tissue Doppler velocity (E/Ea), urinary albumin–creatinine rate (UACR) and estimated glomerular filtration rate (eGFR).
Results: Although LVMI, E/Ea and eGFR were significantly different among subjects with or without ARS and/or ATS (P<0.02), in full adjustment model, only E/Ea showed the independent and significant difference (P=0.023). Moreover, E/Ea was significantly different between participants with ARS or ATS and those without ARS or ATS (P=0.045), while there was no significant difference between participants with ARS and ATS and those without ARS or ATS (P=0.28). Similar results were obtained in the multivariate logistic regression of left ventricular diastolic dysfunction (LVDD). With similar adjustment, LVDD was significantly associated with ATS (P=0.01) but not with ARS (P=0.99).
Conclusion: In the community-dwelling elderly Chinese, among hypertensive TOD, LVDD was significantly associated with ATS but not with ARS. The proportion of patients with LVDD was not significantly different despite the presence of both ATS and ARS, when compared to patients with ATS alone.
