2012-12-19 15:53

We know that kidneys are vital for maintaining normal life activities by filtering the blood---useful substances will be returned to the blood and metabolic wastes and toxins will be discharged along with urine.

In case of kidney failure, part or all kidney functions are damaged and some metabolic wastes can not be cleared outside timely or efficiently. They will instead stay in the body and circulate into various organs and systems with blood circulation. It this conditions can not be rectified, these harmful products such as uric acid, BUN and creatinine will damage the body and cause systemic symptoms and discomforts. Among all these symptoms and signs, cardiovascular lesion is one of the major complications and the most common cause of death of end stage renal failure.

The common cardiovascular diseases include hypertension, left ventricular hypertrophy, heart failure, uremic cardiomyopathy, pericardial effusion, pericarditis, vascular calcification and atherosclerosis, etc.

Actually the lesions and damages in many organs and systems will interact and worsen each other. It has been found recently that electrolyte imbalances paly certain role in cardiovascular diseases. High blood phosphorus, abnormal distribution of calcium and lack of vascular protective proteins like fetuin A can cause calcification of blood vessels and worsen cardiovascular lesions.

Besides regular taking of prescribed medicines and follow-up examinations, patients should pay more attention to monitor their blood pressure and blood sugar level which are two major risk factors for speeding up glomerular sclerosis and decline of renal functions.

The following are some health tips for lowering the risk of developing cardiovascular diseases and reducing mortality of chronic kidney failure.

·Limit salt intake. High-salty diets can increase the risk of cardiovascular diseases and for those that have serious high blood pressure or heart failure, daily salt intake should be limited within 1-2g.

·Have more foods that are rich in vitamin C such as fruits and vegetables. Vitamin C can increase vascular elasticity and protect blood vessels.

·Have more intake of fiber which can absorb cholesterol and lower cholesterol concentration.
