The latest data from the hypertension survey shows that the prevalence of hypertension among residents aged 18 and above in China is about 27.9%, and a series of complications caused by hypertension have become the first major cause of death, ranking second to cancer. The higher the patient’s blood pressure, the greater the risk of damage to the blood vessels of the heart, brain, kidneys and other major organs, resulting in serious complications such as strokes, coronary heart disease and uremia. Stroke Stroke, also known as stroke, is currently the most significant complication of hypertension in China, with high rates of death and disability. Most of them are ischemic strokes. Symptoms at the onset are abnormal sensation or loss of sensation on one side of the body, speech impairment, confusion, visual impairment, dizziness, loss of balance or incoordination, etc., which require urgent medical treatment. After stabilization, patients need to take continuous antihypertensive medication to stabilize blood pressure at 140/90 mmHg, which can effectively reduce the recurrence rate of stroke. Rehabilitation may also be required if there is physical impairment. Heart damage It has been found that the higher the level of hypertension and the longer the duration of the disease, the more severe or extensive the stenosis of the coronary arteries, which in severe cases affects the blood supply to the heart muscle and causes coronary heart disease. Temporary chest pain or pressure in the chest, known as angina, occurs when there is insufficient oxygen supply to the heart muscle and may spread to the back, jaw, left and right arms, shoulders, and abdomen. Some patients may experience shortness of breath, profuse sweating, dizziness, or even fainting and sudden death, requiring immediate medical attention. Smooth control of blood pressure is the key to treating hypertension combined with coronary heart disease. For patients with hypertension combined with coronary heart disease, the goal of lowering blood pressure is 140/90 mmHg or less, and antihypertensive drugs need to be used under the guidance of a doctor. In addition, hypertension can lead to heart failure, and in severe cases, even cause bruised edema in the lungs, lower limbs and other tissues. Kidney damage Most hypertensive patients are accompanied by varying degrees of kidney function damage, if blood pressure is not well controlled, it can gradually develop into glomerulosclerosis, renal insufficiency, and eventually progress to uremia. In turn, nephropathy further increases blood pressure, forming a vicious circle. It is now clear that the blood pressure of patients with chronic kidney disease should be controlled below 130/80mmHg. In conclusion, the complications of hypertension are serious, therefore, patients should pay more attention to their blood pressure on a daily basis, take antihypertensive drugs under the guidance of doctors, and abandon poor lifestyle, avoid high sodium and low potassium diet, quit smoking and limit alcohol, and exercise more, which are important measures to prevent the rise of blood pressure.
