Abstract

Increased intima-media thickness (IMT) of common carotid artery (CA) is considered the hallmark of vascular hypertension-mediated target organ damage, even if vessel remodeling due to mechanical stress may also induce changes in diameter. We developed a method computing both diameter and IMT of CA, to assess correlates and prognostic impact of carotid cross-sectional area (CCSA) in a large registry of treated hypertensive patients. We selected 6300 hypertensive patients of the Campania Salute Network registry free of overt cardiovascular (CV) disease and with available CA ultrasound (54 ± 11 years; 57% male). CCSA was computed as:π×(CAdiameter+2×(meanIMT)2)2−π×(CAdiameter2)2. CCSA was considered high if >90th percentile of the sex-specific distribution (>48 mm2 in men and >41 mm2 in women). Patients with high CCSA were male, with older age, higher pulse pressure (PP), more prevalent obese and diabetic, with higher total and LDL cholesterol (p < 0.01 for all). During a median follow-up of 60 months (IQR 19–87), 206 incident composite major and minor CV events occurred. In Cox regression analysis high CCSA was associated with more than 100% increased risk of incident CV events ((HR 2.11, 95%CI 1.46–3.1, p < 0.0001), independently of the effect of older age, male sex, PP > 60 mmHg, presence of left ventricular hypertrophy (LVH), carotid plaque (CP), and less anti-RAS therapy (p < 0.05 for all). In treated hypertensive patients, increased CCSA is associated with worse metabolic and lipid profile and predict incident CV events, independently of high PP, presence of LVH and CP.
