OBJECTIVE: The aim of this study was to evaluate the left ventricular (LV) function by conventional two-dimensional speckle tracking echocardiography (2D STE) to detect subclinical LV systolic dysfunction in patients with dipper and nondipper hypertension. METHODS: One hundred consecutive patients with hypertension were included in our study. Clinical evaluation, baseline laboratory investigations, 24 ambulatory blood pressure monitoring 2D echocardiographic examination and 2D STE were performed for all patients. Patients were classified as dippers and nondippers according to their nighttime MAP (mean arterial blood pressure) reduction rate of ≥10 or <10%, respectively. RESULTS: Of 100 patients, 71% were nondippers while 29% were dippers. Nondippers had a significantly lower global longitudinal strain (LS) value (-22.45 ± 3.26 vs. -18.2 ± 3.3, P < 0.001), global circumferential strain (CS) value (-24.23 ± 3.56 vs. -19.16 ± 8.25, P < 0.001) and global radial strain (RS) value (35.04 ± 11.16 vs. 29.58 ± 8.44, P = 0.009). It was found that nondipper status was associated with worsening of LS by 2.737, (P = 0.001), CS by 3.446, (P = 0.002), RS by -3.256, (P = 0.158) and DM also was found associated with worsening of LS by 1.849, (P = 0.062), CS by 3.284 (P = 0.018), RS by -2.499 (P = 0.381). CONCLUSION: The nondipping hypertension pattern is associated with subclinical LV systolic dysfunction as shown by the impaired global myocardial strain in all three directions.
