Document Details : Title: Lack of increased left main coronary artery dimensions in hypertensive patients with left ventricular hypertrophy and coronary artery disease Subtitle: An intracoronary ultrasound study Author(s): VAVURANAKIS, Manolis , RIGOPOULOS, Agelos , VAINA, Sofia , CHRYSOHOOU, Christina , TOUTOUZAS, Konstantinos , STAMATOPOULOS, Ilias , STEFANIDIS, Christodoulos Journal: Acta Cardiologica Volume: 59 Issue: 4 Date: August 2004 Pages: 397-403 DOI: 10.2143/AC.59.4.2005205 Abstract : Objectives — Left main coronary artery dimensions were evaluated in patients with and without arterial hypertension, in the presence of coronary artery disease, and correlated to left ventricular mass. Methods and results — Intracoronary ultrasound was performed in 25 patients (pts) with coronary artery disease and hypertension (+HTN) and in 25 pts with coronary artery disease only (–HTN). Maximal left main dimensions and left ventricular mass index (LVMI) were measured. +HTN pts had greater LVMI compared to –HTN, (+HTN = 183 ± 17 g/m2 vs. –HTN = 82 ± 22 g/m2, p < 0.0001), while maximal left main vessel area was similar (25.99 ± 5.01 mm2 vs. 25.62 ± 3.3 mm2, p = 0.8). No correlation was found between LVMI and left main vessel area in + HTN. Conclusions — Pts with +HTN despite the increased LVMI do not manifest increased LM dimensions. This may affect mid-term clinical outcome. |
