| Popis: | Background. During the last decade, control of hypertension, oedema, anaemia, uraemia, and blood glucose has improved in patients with diabetic nephropathy. We have investigated whether this has influenced cardiac function at the time of end-stage renal failure. Study design. Echocardiographic investigations were performed in 26 type 1 diabetic patients evaluated for kidney transplantation and the results compared with those obtained in healthy controls and in a similar group of patients investigated in 1977-1980. Results. Blood pressure was 153±121/851±12 mmHg versus 174±17/91±9 (recent group versus early group). The left ventricular (LV) diameter index, a measure of volaemia, was increased in systole and diastole in the early but not in the recent group. Both groups had LV hypertrophy, but this was much less pronounced in the recent group ; posterior wall thickness was 1.1 ± 0.16 cm versus 1.3 ± 0.26 cm (P = 0.0001) and LV mass index 132±43 g/m 2 versus 166±44 g/m 2 (P = 0.009). Blood pressure correlated significantly with indices of LV hypertrophy in the recent group. Systolic function was normal in both groups but diastolic function was disturbed in both and to the same extent, atrial systole contributing by 27±14%, to ventricular filling. Conclusion. Better treatment of hypertension, fluid overload, and uraemia has led to less pronounced LV hypertrophy. The remaining correlation with blood pressure suggests that more could be gained by intensified antihypertensive treatment. |
