Abstract:
BACKGROUND:Left ventricular (LV) global longitudinal strain (GLS) can detect an early dysfunction in arterial hypertension. We investigated regional LV patterns of longitudinal strain (LS) and base-to-apex behaviour in newly diagnosed, never-treated hypertensive patients (HTN) without LV hypertrophy. METHODS:180 HTN and 115 healthy controls underwent standard echocardiography, including regional LS and GLS assessment (in absolute values). The average LS of six basal (BLS), six middle (MLS), and six apical (ALS) segments and relative regional strain ratio = [ALS/(BLS + MLS)] were also computed. RESULTS:The two groups were comparable for sex, age and heart rate. Body mass index (BMI), systolic, diastolic and mean blood pressure (BP) (all p < 0.0001) were higher in HTN. Despite LV ejection fraction (EF) was comparable, GLS, BLS and MLS resulted lower in HTN (all p < 0.0001), without difference in ALS. Relative regional strain ratio resulted higher in HTN (p < 0.001). Dividing HTN group according to lower normal values derived from the controls, BLS was able to identify a higher rate of LV dysfunction than GLS. By a multiple linear regression analysis performed in the pooled population after adjusting for age, sex, BMI, end-systolic stress, relative wall thickness and LV mass index, the association between BLS and mean BP remained significant (β coefficient = -0.42, p < 0.0001), despite the significant impact of male sex. In a similar model, MLS and mean BP resulted also independently associated (β = -0.21, p < 0.002). CONCLUSIONS:Despite normal LV EF, LS dysfunction is detectable in HTN, mainly involving basal and middle segments, resulting in higher relative regional strain ratio.
