Whether a hypertensive patient is at risk is not only related to the level of blood pressure, but also to the presence of other risk factors and the degree of target organ damage. Mild hypertension alone does not require drug treatment; if other risk factors are combined with hypertension, long-term ineffective control of blood pressure may result in target organ damage or even life-threatening injury. 1. If the systolic blood pressure (high pressure) is 140mmHg and diastolic blood pressure (low pressure) is 90mmHg, and the blood pressure is simply elevated, according to the diagnostic standard of hypertension, 140/90mmHg belongs to grade 1 hypertension, that is, mild hypertension, which doesn’t need medication, and only needs to improve the lifestyle, such as quitting smoking and drinking, controlling body weight, low-salt and low-fat diets, and moderate exercise. 2. If on the basis of grade 1 hypertension, there are diabetes, high blood fat, family history of cardiovascular disease, coronary heart disease, cerebrovascular disease or chronic kidney disease, then even if it is grade 1 hypertension, it is very dangerous not to control it. For example, there will be fundus retinopathy causing blindness; heart blood vessels, myocardial injury, causing myocardial infarction, heart failure; cerebrovascular atherosclerosis, ischemia, degeneration, there is a risk of cerebral thrombosis, cerebral hemorrhage; renal atherosclerosis, glomerulonephritis, fibrosis and atrophy, there is a risk of causing a continuous decline in renal function or even renal failure. Therefore, whenever an increase in blood pressure occurs, it is necessary to go to the hospital in a timely manner and ask the doctor to conduct a risk assessment in order to decide on the subsequent treatment and follow-up program, and do not take it lightly, so as not to cause adverse consequences.
