    Index of myocardial performance in patients with type 2 diabetes without hypertension and its relationship with clinical and echocardiographic parameters
    (Wiley, 2009) Saglam, Hayrettin; Seyfeli, Ergun; Gul, Ibrahim; Duru, Mehmet; Gokce, Cumali
    Background: Diabetes mellitus affects the systolic and diastolic function of the left ventricle (LV). The aim of the present study was to evaluate the index of myocardial performance (IMP), a new Doppler index, in asymptomatic, normotensive patients with type 2 diabetes mellitus (T2DM). Methods: The study population consisted of 40 asymptomatic normotensive patients with T2DM (22 women, 18 men; mean [+/- SD] age 49 +/- 7 years) and 20 healthy controls (13 women, seven men; mean age 45 +/- 4 years). M-Mode and two-dimensional Doppler echocardiography was performed in all subjects to calculate IMP. Venous blood samples were collected for analysis and body mass index (BMI) was calculated. Results: In normotensive T2DM patients, the mitral E wave was decreased, whereas mitral A wave, mitral E/A ratio, and septal wall thickening were increased compared with values obtained for the control group. The IMP was higher in normotensive T2DM patients than in the control group (P = 0.004). There was a significant correlation between IMP and triglyceride (TG) levels (P < 0.001), mitral E wave (P < 0.001), mitral E/A ratio (P < 0.001), ejection fraction (P = 0.001), fasting blood glucose (P = 0.007), LV systolic dimension (P < 0.001), duration of diabetes (P = 0.017), and BMI (P = 0.029). Stepwise multiple regression analysis demonstrated that only TG levels (beta = 0.355, t = 2.487, P = 0.017) and the mitral E/A ratio (beta = -0.384, t = -2.690, P = 0.011) had an independent effect on IMP. Conclusion: The results of the present study indicate that IMP is increased in normotensive T2DM patients. The findings suggest that increased IMP may be an early sign of diabetic cardiomyopathy in normotensive diabetic patients with preserved LV function.

    P wave dispersion in patients with rheumatoid arthritis: its relation with clinical and echocardiographic parameters
    (Springer, 2007) Guler, Hayal; Seyfeli, Ergun; Sahin, Gunsah; Duru, Mehmet; Akgul, Ferit; Saglam, Hayrettin; Yalcin, Fatih
    P wave dispersion (PWD) is a sign for the prediction of atrial fibrillation (AF). The aim of this study was to assess P wave dispersion and its relation with clinical and echocardiographic parameters in patients with rheumatoid arthritis (RA). Thirty RA patients (mean age 49 +/- 10 years) and 27 healthy controls (mean age 47 +/- 8 years) were included in the study. We performed electrocardiography and Doppler echocardiography on patients and controls. Maximum and minimum P wave duration were obtained from electrocardiographic measurements. PWD defined as the difference between maximum and minimum P wave duration was also calculated. Maximum P wave duration and PWD was higher in RA patients than controls (P = 0.031 and P = 0.001, respectively). However, there was no significant difference in minimum P wave duration between the two groups (P = 0.152). There was significant correlation between PWD and disease duration (r = 0.375, P = 0.009) and isovolumetric relaxation time (r = 0.390, P = 0.006). P wave duration and PWD was found to be higher in RA patients than healthy control subjects. PWD is closely associated with disease duration and left ventricular (LV) diastolic dysfunction.

    Right ventricular diastolic abnormalities in rheumatoid arthritis and its relationship with left ventricular and pulmonary involvement. A tissue Doppler echocardiographic study
    (Springer, 2006) Seyfeli, Ergun; Guler, Hayal; Akoglu, Sebahat; Karazincir, Sinem; Akgul, Ferit; Saglam, Hayrettin; Seydaliyeva, Tunzale
    Objectives To investigate right ventricular diastolic function in rheumatoid arthritis (RA) and its relationship with left ventricular and pulmonary involvement. Methods Thirty-five RA patients and 30 healthy subjects were submitted to conventional Doppler (CE) and tissue Doppler echocardiography (TDE) to assess left and right systolic and diastolic function and to estimate maximal arterial systolic pulmonary pressure (PAP). To detect pulmonary involvement, pulmonary function tests and high-resolution computed tomography (HRCT) scans were performed in all RA patients. Results An abnormal RV filling, as expressed byan inverted tricuspid (Tr.) E/A ratio, was detected in 12 (34%) of the 35 RA patients and in 2 (7%) of the 30 controls (P < 0.004). If compared to CE findings, prevalence of RV diastolic abnormalities were found higher in patients with RA by TDE (RV annulus Em/Am ratio < 1 (in 31 (89%) of 35 patients) (P=0.002). Twenty-two (63%) of 35 patients had abnormal HRCT findings. Pulmonary involvement with pulmonary hypertension (PHT) (36 +/- 5 mmHg) was detected in 10 (29%) of 35 RA. In this group, increase of RV annulus and basal Am wave, decrease of Tr. E/A ratio and RV annulus Em/Am ratio were statistically significant compared to RA (12 (34%) of 35) patients with pulmonary involvement who had normal PAP (19 +/- 5 mmHg), (P=0.014, P=0.006, P=0.015, P=0.049, respectively). Conclusions This study points out an impaired RV filling in a significant part of RA patients without overt heart failure. Impairment of RV diastolic function may be a predictor of subclinic myocardial and pulmonary involvement in patients with RA.
