When it comes to hypertension, we are no stranger to the epidemic of recent years, which is one of the most common chronic diseases in our lives and the most important risk factor for cardiovascular and cerebrovascular diseases. The prevalence of hypertension in our population is still growing, with one in five adults suffering from hypertension; it is estimated that there are at least 200 million hypertensive patients in the country; however, the awareness rate, treatment rate and control rate of hypertension are low. First, what is blood pressure? The blood pressure we normally refer to is the arterial blood pressure, which is the pressure formed on the side walls of the blood vessels when blood flows in the arteries, and also the driving force that pushes the blood to flow in the blood vessels. Second, how is blood pressure classified? Blood pressure is divided into systolic pressure (high pressure) and diastolic pressure (low pressure). The systolic pressure is the side pressure generated by the blood ejected from the left ventricle to the arterial blood vessel wall when the heart is contracting, and this is when the blood pressure is at its maximum, and this forms the high pressure that we are talking about; the diastolic pressure is the side pressure formed by the blood flowing into the artery at the end of the heart’s diastole, when the blood temporarily stops shooting into the artery, and the blood already flowing into the artery continues to flow by the elasticity and tension of the blood vessel wall, and this forms the low pressure that we are talking about. Third, what is the normal value of blood pressure? Ideal blood pressure value: systolic blood pressure <120
mmHg, diastolic blood pressure <80mmHg.
Normal blood pressure values: 90 mmHg < systolic < 140 mmHg; 60 mmHg < diastolic < 90 mmHg. Fourth, how to diagnose hypertension? Systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg measured on 3 non-same-day occasions without the use of antihypertensive drugs. systolic blood pressure ≥ 140 mmHg and diastolic blood pressure < 90 mmHg is considered simple systolic hypertension. The patient had a previous history of hypertension and was currently on antihypertensive medication, and her blood pressure was diagnosed as hypertensive even though it was below 140/90 mmHg. Nowadays, hypertension is not only a health medical problem, but also has a significant impact on society, so it is important for everyone to be fully aware of hypertension.
