10 Therefore, if LV systolic function is not known, the correlation between PWV and LV diastolic function is difficult to determine.Ī clinical device, ABI-form (Colin VP1000, Komaki, Japan), has been developed to automatically and simultaneously measure blood pressure (BP) in both arms and ankles, and record pulse waves of the brachial and posterior tibial arteries by an automated oscillometric method. Thus, they concluded that aortic PWV values were susceptible to LV performance. also evaluated the relationship between aortic PWV and LV systolic function in 63 patients with cardiomyopathy (LV ejection fraction 50%), and found that aortic PWV did not differ between cardiomyopathy patients and controls, and that aortic PWV had a significant positive correlation with LV ejection fraction in cardiomyopathy patients. However, one of our recent studies revealed that there was a mismatch between increases in arterial stiffness and LV diastolic dysfunction in patients with wide range of LV systolic function. 6, 7, 8 In these studies, 4, 5, 6, 7, 8 they chiefly included patients with preserved LV systolic function. Several studies have also reported a relationship between arterial stiffness and LV diastolic function. 5 demonstrated that aortic PWV progressively increased according to the severity of diastolic dysfunction and had a significantly negative correlation with early diastolic mitral annular velocity (Ea). 4 found that brachial-ankle PWV (baPWV) was significantly correlated with left ventricular (LV) diastolic function. Increased pulse wave velocity (PWV), which reflects increased arterial stiffness, is reported to be an independent predictor of cardiovascular outcomes 1, 2 and is associated with the presence of coronary artery narrowing. When interpreting the relationship between baPWV and LV diastolic function, the rbPEP/rbET value obtained from the same examination should be considered. In patients with high rbPEP/rbET but low baPWV, low baPWV may not indicate good LV diastolic function but implies that cardiac dysfunction may precede vascular dysfunction in such patients. In conclusion, rbPEP/rbET had an impact on the relationship between baPWV and LV diastolic function. Patients in group 2 had a LAVI and ratio of transmitral E wave velocity to Ea that were comparable to those in groups 3 and 4. Patients in group 1 had a lower left atrial volume index (LAVI) and higher early diastolic mitral annular velocity (Ea) than patients in the other groups ( P≤0.002). The LV ejection fractions in groups 1 and 3 were higher than those in groups 2 and 4 ( P<0.001 for all). Groups 1, 2, 3 and 4 were patients with rbPEP/rbET and baPWV below the median, rbPEP/rbET above but baPWV below the median, rbPET/rbET below but baPWV above the median, and rbPET/rbET and baPWV above the median, respectively.
Patients were classified into four groups. The brachial-ankle pulse wave velocity (baPWV) and the ratio of right brachial pre-ejection period to ejection time (rbPEP/rbET) were measured using an ABI-form device. A total of 260 patients were included in the study. Therefore, if LV systolic function is not known, the relationship between arterial stiffness and LV diastolic function is difficult to determine. This applies only if the systems are used by the same person and not multiple users.Arterial stiffness is correlated with left ventricular (LV) diastolic function as well as susceptibility to LV systolic function.
