Background Arterial elastance to left ventricular elastance ratio assessed by echocardiography is widely used as a marker of ventricular‐arterial coupling. Materials and methods We investigated whether the ratio of carotid‐femoral pulse wave velocity, as a marker of arterial stiffness, to global longitudinal strain, as a marker of left ventricular performance, could be better associated with vascular and cardiac damage than the established arterial elastance/left ventricular elastance index. In 299 newly‐diagnosed untreated hypertensives we measured, carotid‐femoral pulse wave velocity, and carotid intima‐media thickness, coronary‐flow reserve, arterial elastance/left ventricular elastance, global longitudinal strain, and markers of left ventricular diastolic function ( E / A and E ’) by echocardiography. Results Pulse wave velocity‐to‐global longitudinal strain ratio (PWV/GLS) was lower in hypertensives than controls (−0.61 ± 0.21 vs −0.45 ± 0.11 m/sec%, P < 0.001). Low PWV/GLS values were associated with carotid‐intima media thickness > 0.9 mm ( P = 0.003), E/A ≤ 0.8 ( P = 0.019) and E ’ ≤ 9 cm/sec ( P = 0.002) and coronary‐flow reserve < 2.5 ( P = 0.017), after adjustment for age, sex and mean arterial pressure. Low PWV/GLS was also associated with increased left ventricular mass and left atrial volume in the univariate ( P = 0.003 and 0.038) but not in the multivariate model. In hypertensives, there was no significant association of arterial elastance‐to‐left ventricular elastance index with carotid intima media thickness, coronary flow reserve, E / A , E ’, or left atrial volume with the exception of an inverse association with left ventricular mass ( P = 0.027). Conclusions Pulse wave velocity‐to‐global longitudinal strain ratio but not the echocardiography‐derived arterial elastance‐to left ventricular elastance index is related to impaired carotid‐intima media thickness, coronary‐flow reserve and diastolic function in hypertensives.
