A blood pressure of 160 mmHg systolic and 90 mmHg diastolic is considered second-degree hypertension, which requires medication according to the indications for which the antihypertensive medication is intended. Hypertension is defined as a syndrome of cardiovascular disease characterized by elevated arterial blood pressure in the physical circulation, and can be divided into two main types: primary hypertension and secondary hypertension. Primary hypertension, also known as hypertensive disease, has an unknown etiology, but is considered one of the most important risk factors for cardiovascular disease because it is often combined with other cardiovascular risk factors. When the blood pressure is in the second level and above, medication is often needed to intervene in order to control the blood pressure within a reasonable range, which is of great significance to the prognosis of cardiovascular disease, so patients with high blood pressure should pay attention to it and seek medical treatment in a timely manner.
