Abstract:

Introduction: In this study, we evaluated the left ventricular diastolic functions in RA patients using the traditional Doppler and a new eco-cardiographic technique of tissue Doppler imaging (DDG). Method: Our study included 46 RA patients and 31 healthy individuals. The duration of the disease was between 0 and 12 years (an average of 4.2 ± 4.3 / year). All patients and control groups were evaluated with M-mode, 2-D, traditional Doppler ecocardiography and DDG. Results: Basic clinical and ecocardiographic parameters in the RA group with the control group, the left atrium diameter, the left ventricular diameter, the left ventricular injection fraction, the left ventricular wall thicknesses were similar in both groups. Of the traditional Doppler mitral flow parameters, the values of early diastolic flow velocytes (E) (p = 0,001), late diastolic flow velocytes (A) (p = 0,03) and deceleration time (p ≤ 0,001) were higher in RA patients compared to the control group. According to the control group, the ratio of E/A in the RA group was lower (p ≤ 0,001). The mitral annulator of the DDG parameters was found lower in the RA group (p = 0,01) compared to the early diastolic speed wave control group. The later diastolic speed wave of the mitral annuler was found higher (p = 0,007). Result: Compared with the control group with RA patients with similar characteristics in age and gender, the traditional Doppler and tissue Doppler parameters were deteriorated in RA patients.
