When you are irritable, you will have increased blood pressure: 1. Long-term irritability will lead to sympathetic overexcitation, and sympathetic excitement will lead to increased blood pressure, faster heart rate, increased myocardial contraction, faster heart conduction speed, increased myocardial oxygen consumption and a series of other changes, which will eventually lead to hypertension. 2. Irritability will lead to activation of the renin-angiotensin-aldosterone system in the body, and therefore, when a large amount of renin is secreted, it will further lead to hypertension. 3, when the temper will appear in the body nerve, body fluids, endocrine system disorders, which will also lead to an increase in blood pressure. Therefore, patients who are irritable are prone to hypertension, and once they have hypertension, they are also prone to cardiovascular and cerebrovascular involvement, resulting in impaired function of other organs.
