Prevalence of the presystolic wave in echocardiography and its association with the extent of coronary artery disease in patients with chronic stable angina

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

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.

RESULTS

The 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).

CONCLUSION

LVOT presystolic wave is associated with systemic hypertension and it could be used as a predictor for systemic hypertensive patients.
