When it comes to hypertension, many young people pay more attention to the systolic pressure (high pressure) is elevated, while the systolic pressure is not high, diastolic pressure (low pressure) is elevated is not bothered. I do not know, simply high diastolic blood pressure is also hypertension, its harm should not be underestimated. Clinical data show that people with normal systolic blood pressure and diastolic blood pressure of 105-110 mmHg are three to five times more likely to have cardiovascular complications than those with diastolic blood pressure of 70-75 mmHg. It can be seen that high diastolic blood pressure is also a risk factor for cardiovascular and cerebrovascular disease. Why high pressure is not high and low pressure is high The formation of blood pressure depends on five factors, including the elasticity of large blood vessels, the contractility of the heart, the viscosity of blood, and peripheral vascular resistance. The maximum value of arterial blood pressure that is reached during ventricular contraction is called systolic pressure; and because of the elasticity of the arteries, part of the energy released during ventricular contraction is stored in the form of elongated elastic fibers in the wall, and the pressure that pushes blood flow to continue during diastole is called diastolic pressure. Diastolic pressure alone is high in young people, because young people have better elasticity of the aorta, when the heart discharge blood flow to the aorta is easy to expand, so the heart is not difficult to fight blood, systolic pressure is not high. However, when the heart is diastolic, the aortic elasticity retracts strongly, plus the surrounding blood vessels are in a state of contraction, and the pressure generated at this time will lead to an increase in diastolic pressure. The reason why high diastolic blood pressure favors young and middle-aged people, especially white-collar workers and students, is that high diastolic blood pressure is the result of pressure. The “fatigue” of the non-normal fast lifestyle, so that the body and mind often in the stress of tension, resulting in sympathetic hyperexcitation, promote the release of norepinephrine, and activate the renin-angiotensin-aldosterone system, so that vasoconstriction, peripheral resistance increased, resulting in elevated diastolic blood pressure. In addition, the lack of exercise, often stay up late, smoking and alcohol, fatty meat, impatience and irritability …… can make the diastolic blood pressure rise. What are the dangers of high diastolic pressure alone High diastolic pressure alone is the initial stage of hypertension, patients often have headaches and dizziness, chest tightness and breathlessness, palpitations and discomfort, fatigue and sleepiness, etc. With age, the course of the disease is prolonged, pure diastolic hypertension can be transformed into classical hypertension, or even to the development of pure systolic hypertension. Ultimately, it can cause damage to important organs such as heart, brain and kidney, such as heart failure, arrhythmia, atherosclerosis, cerebrovascular accident, damage to the kidney, retinal hypofunction, and coronary heart and myocardial infarction and stroke are the most serious complications of hypertension. Therefore, hypertension with high diastolic blood pressure alone should not be taken lightly. If the diastolic pressure is less than 95 mm Hg, non-pharmacological treatment can be used, starting with lifestyle improvement. Release the mind. Regulate and harness your emotions, be emotionally happy and psychologically balanced, and your elevated diastolic blood pressure will naturally drop. Get up and live regularly. Do a regular life, rest and rest at times, work and rest, to ensure sleep, conducive to the normal operation of the biological clock “will be in a stable state of blood pressure. Eat a light diet. Eat three meals a day should be light, less greasy, avoid alcohol, summer if sweating, the amount of salt can be increased to 8 grams, and drink more plain water. Eat more vegetables and fruits rich in vitamin C, potassium and calcium every day to help lower blood pressure and protect cardiovascular health.
