Abstract
There might be limitations in identifying concentric left ventricular (LV) geometry by ratio of diastolic posterior wall thickness (WT(p)) to cavity radius, defined as relative wall thickness (RWT(p)). This study has been designed to evaluate age effects on RWT(p). WT(p), mean of septal thickness and WT(p) (WT(m)), and cavity radius were cross-sectionally evaluated in 766 1- to 85-year-old, normotensive, nonobese subjects and 331 hypertensive Italians (used as a test series). RWT(p) > or =0.43 defined "traditional" concentric LV geometry. The ratios WT(m)/radius (RWT(m)) and RWT(p) increased by 0.005 and 0.006 per year of age in the age stratum up to 17 years and by 0.002 in the older age stratum (18 years or older; all P0.41 or RWT(p) >0.40. Further studies are required to establish prognostic implications of our findings.Keywords
