Abstrakt: Background: It is known that non-dipper pattern (NDP) is associated with adverse outcomes in hypertensive patients. However, there is insufficient data on the outcome of NDP in normotensive individuals. Using myocardial work (MW) analysis, as a new echocardiographic examination method, this study aimed to determine the early myocardial effects of NDP in normotensive individuals.
Methods: This study included 70 normotensive individuals who were followed by ambulatory blood pressure monitoring (ABPM). The subjects were divided into two groups according to dipper pattern (DP) and NDP. Conventional, strain, and MW findings were compared between the groups by making echocardiographic evaluations.
Results: The demographic characteristics, laboratory parameters, and measurements of cardiac chambers, and left ventricular (LV) walls were similar between the groups. There was no statistical difference between the groups in terms of LV 3-2-4 chambers strains and global longitudinal strain (GLS) values. LVMW parameters, global work index (GWI), and global constrictive work (GCW) were not statistically different between groups (2012 ± 127, 2069 ± 137, p = 0.16; 2327 ± 173, 2418 ± 296, p = 0.18, respectively). However, global waste work (GWW) and global work efficiency (GWE) parameters were different between the groups (144 ± 63.9, 104 ± 24.8, p < 0.001; 93.2 ± 3.17, 95.4 ± 1.28, p < 0.001, respectively). In regression analysis, GWW was independently associated with NDP. GWW model showed better results with higher likelihood chi-square and R 2 values than GLS model in discriminating the predictable capability for NDP status.
Conclusion: The results of MW analysis in this study showed that GWW values were higher and the GWE values were lower in normotensive individuals with NDP.
