Can Chronic Renal Failure Cause Heart Failure

Heart Failure is a serious complication of Chronic Renal Failure and also an important death cause for them. Heart Failure is caused by several factors, as follows:

1. Many patients with Chronic Renal Failure are also complicated with high blood pressure and high blood fat after dialysis, which can accelerate the atherosclerosis thus making the death rate increase.

2. In uremic period, the patients’ immune is very weak. It is very likely to cause infection thus leading to myocarditis and pericarditis, which can increase the incidence of Heart Failure.

3. If the patients keep high blood pressure over time, it can cause excessive burden to hearts. It can lead to ventricular wall to become thick and amplify heart thus causing Heart Failure. In addition, high blood pressure also accelerates atherosclerosis progression, which can enhance the incidence of Heart Failure.

4. Renal anemia can lead to myocardial ischemia thus making its function to decline. For body’s compensation, the hearts have to overwork so causing extra burden to hearts. It the heart keeps tired over time, which will aggravate myocardial ischemia thus causing Heart Failure.

5. As the renal function declines, the kidneys can not discharge the uremic toxins in body. The toxins can restrain the myocardium thus causing myocardial function to decline and Heart Failure.

6. Electrolyte disturbance and acidosis can change the cardiac excitability thus causing arrhythmia and Heart Failure.

7. When the blood volume increases for the patients with Chronic Renal Failure, the stroke volume and cardiac output will increase. When the hearts’ compensatory ability is insufficient, the left ventricle function will decline thus causing Heart Failure.


As Heart Failure can threaten patients’ life seriously, it is very important for the patients with Chronic Renal Failure to take preventive measures against its happening.
