The heart and the kidney have always been a pair of inseparable brothers, and with the incidence of chronic kidney disease rising year by year, the relationship between the two has received more and more attention from the medical community. Many kidney disease patients have died of heart disease far before their condition progressed to kidney failure. But less attention is often paid to the kidneys than to the heart. The occurrence of kidney disease will accelerate the deterioration of heart disease, and heart disease is likely to be manifested in the form of kidney disease, that is, kidney disease and heart disease “auxiliary car dependent on the lips and teeth”. The interaction between kidney disease and heart disease is quite complex. Once kidney problem occurs, the risk of heart problem also increases, and this connection has already occurred in the early stage of kidney disease. A deterioration in any of the physiological indicators of the kidneys can lead to increased cardiac morbidity, while those diagnosed with heart disease at an early stage are twice as likely as others to have problems with kidney function. That’s why heart patients should never forget to check their kidneys in order to nip kidney disease in the bud. Similarly, when kidney indicators deteriorate, people should also keep an eye on their heart at the same time. In our prevention and treatment of chronic kidney disease, the first thing to do is to do a good job in the prevention and treatment of cardiovascular disease, to standardize the treatment, to control the patient’s blood pressure, blood lipids, blood sugar levels. Reasonable diet pay attention to nutrition, change bad habits, relieve CKD (chronic kidney disease) symptoms, slow down or reverse the progress of CKD (chronic kidney disease), and make adequate preparation for future replacement therapy. The heart and kidney are both important, protect the kidney and save the heart! is our theme.
