Heart diseases are the leading cause of death in end-stage renal disease. It seems most often related to atherosclerosis and other risk factors found in renal failure like high blood pressure.
Dialysis and the fistula
If you need dialysis, a fistula is created to provide access to your blood. It is done by connecting an artery and a vein, most often on your arm. The fistula, fluid excess, anaemia and hypertension contribute to certain hemodynamic factors that put strain on your cardiovascular system. Insufficient dialysis can also lead to pericarditis, an inflammation of the heart’s outer layers. During dialysis excess fluid are removed and chemicals are balanced. This process is complicated and electrolyte disturbances can lead to irregular heart rhythm. Blood pressure rises if insufficient fluid was removed.
