The relationship of left ventricular outflow tract presystolic wave and 24-h ambulatory blood pressure measurements

Abstract

Objective Left ventricular outflow tract (LVOT) presystolic wave is a novel marker for several cardiac conditions. It is shown to be related to several cardiac conditions. The aim of this study is to investigate the relationship between LVOT presystolic wave and 24-h ambulatory blood pressure measurements.Methods A total of 194 patients who came to the cardiology outpatient clinic were prospectively enrolled in the study. After demographic and clinical inquiry, blood biochemistry and hemogram tests were performed. Each patient was evaluated with echocardiography and 24-h ambulatory blood pressure measurement. The patients were divided into hypertensive and nonhypertensive groups regarding their ambulatory blood pressure measurements and the LVOT presystolic wave of the groups on echocardiography was compared. ResultsThe hypertensive group was significantly older (59.34 ± 11.15 vs. 49.89 ± 15.43; P < 0.001). Presystolic wave presence (96.2 vs. 29.5%; P < 0.001) and velocity (62.23 vs. 29.42; P < 0.001) were higher in patients with hypertension. Blood pressure values and LVOT amplitudes showed a positive correlation (P < 0.001; r = 0.326). In multivariable logistic regression analysis; age, BMI and the presystolic wave were independently associated with hypertension (odds ratio: 8.09; P < 0.001). ConclusionLVOT presystolic wave is associated with systemic hypertension and it could be used as a predictor for systemic hypertensive patients.

The impact of radioactive iodine treatment on subclinical left ventricular dysfunction in patients treated for differentiated thyroid cancer: assessing the predictive value of presystolic wave

“…The role of the presence of presystolic wave was also assessed in hypertensive patients and it was determined that presystolic waves were an independent predictor associated with subclinical LV dysfunction in this patient subset [6]. Several studies have also reported an association between the presence of presystolic wave and arterial stiffness, systemic hypertension, and non-dipping [15][16][17]. There are also studies investigating potential relationships between coronary artery disease and the lack of presystolic waves.…”
