Chronic renal failure, also commonly known as chronic kidney disease (CKD), is a condition involving a decrease in the kidneys" ability to filter waste and fluid from the blood. Chronic renal failure is typically caused by certain medical conditions that put strain on the kidneys over time, including diabetes, high blood pressure or hypertension and long-term inflammation of the kidneys (1).
One in three adults with diabetes are likely to develop chronic renal failure, and one in five adults with high blood pressure are likely to develop chronic renal failure (1). High blood pressure is the second leading cause of chronic kidney disease. About 29% of kidney failure cases in the US are caused by high blood pressure (2).
The kidneys and circulatory system depend on each other for good health. The kidneys help filter wastes and extra fluids from blood, and they use a lot of blood vessels to do so. When the blood vessels become damaged, the nephrons that filter your blood don’t receive the oxygen and nutrients they need to function well. This is why high blood pressure (HBP or hypertension) is the second leading cause of kidney failure. Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. These damaged arteries are not able to deliver enough blood to the kidney tissue (3).
The biggest health risk for people with kidney disease is not actually kidney failure. People with kidney disease are much more likely to develop heart disease or have a stroke. So patients with kidney disease need to keep their heart and blood vessels healthy. Controlling blood pressure is a very important way to do this (4).
So far, a total of 790 patients with chronic renal failure have been diagnosed in Sistan and Baluchestan Province, that receive dialysis services at least two times a week, and approximately 70% of them are caused by high blood pressure. Currently,15 million Iranians are estimated as having high blood pressure, but only 60% of them are aware of their condition. Moreover, only half of the patients receive medication for controlling their disease, and only 19% have their blood pressure under control. Although there is no cure for high blood pressure, it can be managed effectively. Kidney failure due to high blood pressure is a cumulative process that can take years to develop. But, patients can limit their risk by managing high blood pressure.
In Iran more than 96 thousand people die each year due to high blood pressure, and this figure in Sistan and Baluchestan Province was 700 patients in 2018.The implementation of the National "High Blood Pressure Control" campaign can result in early detection and treatment of unidentified cases of high blood pressure, hence preventing long term complications of high blood pressure, including kidney diseases.
