Introduction: Carotid intima media thickness (CIMT), a direct marker of atherosclerosis, has emerged as a promising means for cardiovascular risk evaluation. Presystolic wave (PSW) is commonly detected by the Doppler interrogation of the left ventricular outflow tract (LVOT). It is thought to be a result of a stiff left ventricle and impaired LV compliance. Herein, we aimed to investigate a possible association between carotid intima media thickness, an atherosclerotic marker, and PSW. Method: We prospectively enrolled 282 patients divided into two groups based on the presence of PSW: 221 (89F; mean age: 49.3 ± 11.5 years) had PSW on Doppler examination while 61 patients (32F; mean age: 46.4 ± 10.3 years) did not. Both groups were compared with respect to demographic, clinical properties, and CIMT. Results: Both groups had comparable age, body mass index, and diabetes mellitus, hypertension, dyslipidemia, smoking, and family history for coronary heart disease. PSW‐positive group had significantly higher CIMT (PSW‐positive: 0.59 ± 0.22 mm vs PSW‐negative: 0.42 ± 0.11 mm; P < 0.001) than PSW‐negative group. Multivariate analysis showed that the independent predictors of increased CIMT were age (95% CI; 1.044–1.101, P < 0.001), dyslipidemia (95% CI; 0.147–0.664, P = 0.002), and the presence of PSW (95% CI; 2.168–7.836, P < 0.001).Correlation analysis showed that PSW velocity is correlated with increased CIMT in PSW‐positive group (r: 0.418, P < 0.001). Conclusion: Assessment of PSW on TTE is easy and feasible method. Presence of PSW and increased PSW velocity on TTE might provide information that we should be careful in terms of subclinical atherosclerosis. [ABSTRACT FROM AUTHOR]
