Cardiovascular pathology is frequent in systemic lupus erythematosus (SLE). Left ventricular (LV) diastolic dysfunction is its common findings. The aim of the study was to assess the systolic and diastolic function of the left ventricle (LV) in SLE patients without clinically evident cardiovascular disease, using pulsed Doppler echocardiography. Another purpose was to estimate whether there is a correlation between the duration and severity of SLE and the degree of LV diastolic dysfunction. A comparison of the average values of echocardiographic measurements was made between the SLE group and control group, which constituted healthy volunteers. No statistically significant differences in systolic heart function between groups were observed, except for lower values of the fractional shortening (SF 35.9 +/- 1.2 and 37.1 +/- 0.9, P = 0.01) in SLE patients, particularly in long (more than 10 years) disease duration (34.9 +/- 0.6 vs. 37.0 +/- 0.8, P < 0.005) and the value of SLE Disease Activity Index (SLEDAI) higher than six points (35 +/- 0.9 vs. 37.1 +/- 0.5, P < 0.01) Left atrial end-systolic diameter (LA) was greater (3.69 +/- 0.37 vs. 3.5 +/- 0.28, P < 0.05) and the ejection fraction (EF) was lower (64.6 +/- 1.5 vs. 66.3 +/- 1.3, P < 0.05) in SLE subjects of long disease duration than in the controls. SLE patients demonstrated significantly higher late diastolic velocity (A') and lower E'/A' ratio than the control group. No differences were observed in A' values between SLE subset of short disease duration and the controls. Isovolumetric relaxation time in turn was significantly longer and E/A ratio as well as E'/A' ratio lower in SLE of long disease duration versus the short one. In older patients, peak velocity at the time of atrial contraction (A) and A' values were higher and peak early velocity wave (E), early diastolic velocity (E'), E/A ratio and E'/A' ratio lower than in the younger subset. Increased the value of SLEDAI correlated with increased A' and decreased E, E/A ratio and E'/A' ratio in SLE subjects. Further analysis concerning the strong connection of these parameters with patients' age, however, revealed no statistically significant correlation between SLEDAI values and LV diastolic function parameters. In long (>10 years) disease duration LV diastolic properties were worse.
The results of some epidemiological studies point to the presence of an increased risk of cardiovascular disease (CVD), particularly atherosclerosis and congestive heart failure (CHF) in rheumatoid arthritis (RA). At least 50% of abnormalities remained asymptomatic. Pathological conditions contributing to myocardial dysfunction such as high serum levels of IL-6, C-reactive protein (CRP) and TNF alpha are present both in RA and CHF patients. The most common pathological mechanism leading to the development of heart failure is left ventricular (LV) diastolic dysfunction, which remains clinically asymptomatic for a long time. The aim of this study was to assess the systolic and diastolic functions of the LV in RA patients without clinically evident cardiovascular disease, using pulsed Doppler echocardiography. Our purpose was also to estimate whether there is a correlation between the duration and severity of RA and the degree of LV diastolic dysfunction. A comparison of the average values of echocardiographic measurements was made between the RA group and control group, which constituted healthy volunteers. Left ventricular mass index in RA group was significantly greater than in the control group (105.2 +/- 32.6 vs. 87.9 +/- 16.8; p < 0.05) so were the interventricular septum end-diastolic thickness (1.01 +/- 0.33 vs. 0.86 +/- 0.12; p < 0.05), the LV posterior wall end-diastolic thickness (0.94 +/- 0.08 vs. 0.83 +/- 0.11; p < 0.0001) and the aortic root diameter (3.18 +/- 0.31 vs. 3.10 +/- 0.63, p < 0.001). The ejection fraction in RA group was significantly lower than in the control group (64.4 +/- 1.3 vs. 66.3 +/- 1.3; p < 0.0001). The assessment of diastolic function parameters revealed significantly longer isovolumetrc relaxation time (IVRT) and shorter deceleration time (DT) in RA patients compared to the control group. Patients in stage II or III revealed significantly lower LV mass index (99 +/- 17 vs. 131 +/- 42; p < 0.05) and the interventricular septum end-diastolic thickness (0.94 +/- 0.10 vs. 1.28 +/- 0.5; p < 0.05) than those in stage IV. Mean aortic diameter was significantly greater in individuals in stages III and IV (3.73 +/- 0.28) than in the stage II of the disease (2.77 +/- 0.21), p < 0.05. No differences in echocardiographic parameters' values were observed between seropositive, seronegative, nodule-present and nodule-absent persons. Echocardiographic examination revealed valvular heart disease in 24 (80%) RA and 6 (20%) control patients (p < 0.0001).
The aim of this study was to investigate the work ability in ageing workers suffering from osteoarthritis (OA), coronary heart disease (CHD) or hypertension (H). One hundred and sixty-six OA and 355 CHD/H outpatients were evaluated. The Work Ability Index (WAI) served for work ability assessment. Patients' results were compared with the results of a control group of 225 healthy young workers. Statistical analysis was performed with ANOVA tests. WAI in female and male CHD/H patients was higher than in OA patients (p < .01), better work ability was related to better education (p < .01), white-collar work (p < .01) and better recreation (p < .01); subjective work ability was determined mostly by the objective health status. The promotion of work ability among workers suffering from advanced age-related diseases should be closely related to the promotion of health. It is indicative to improve occupational education and skills, already at an early stage of a disease.
In this exploratory study a test dose predicted the QT response during maintenance treatment with AZD1305 and may thus be employed in further studies. [ClinicalTrials.gov Identifier: NCT00643448].
