- W4287536302 abstract "Early detection of left ventricular (LV) dysfunction may represent a clinical finding that would justify aggressive treatment aimed to reduce cardiovascular morbidity and mortality.To evaluate longitudinal contractility in patients with essential hypertension and preserved LV ejection fraction (EF), in an attempt to detect latent impairment of LV systolic function.Prospective case-control study carried out on 121 (67 male/54 female) hypertensive patients (HTN group) with preserved EF and without any symptoms of heart failure and 39 age- and gender-matched healthy subjects as a control group. Conventional echocardiographic study, as well as 2D Longitudinal strain imaging by 2D-speckle tracking echocardiography (2D-STE), were performed.Mean age of patients was 60,48 ± 10.5 years old. The LV end-diastolic diameter and LVEF were comparable between the two groups. Hypertensive patients had greater septal thickness, left ventricular mass, and maximum left atrium volume (p respectively at 0.02; 0.04; and 0.01). Only 20 patients (16.5%) had left ventricular hypertrophy (LVH). The architecture of LV was normal in 57.8 % (n=70) patients. A statistically significant difference between the two groups was found for all diastolic function parameters except Em /Ea ratio and DTEm. In comparison with normal controls, GLS was significantly attenuated in patients with HTN (-17.69 ± 4.06 % versus -22.70 ± 5.02% in controls (p=0.000) and 67 (55.4%) hypertensive patients had a GLS<-20% (in absolute value). The decrease of GLS was more marked in the hypertensive group with left ventricular hypertrophy.The results of our study confirmed that GLS is a sensitive biomarker of subclinical myocardial dysfunction in hypertensive patients, this suggests that identifying patients at higher risk for heart failure and earlier inter¬vention may be beneficial." @default.
