Anger can have a significant impact on blood pressure, especially in patients with a significant history of hypertension or heart disease, and blood pressure can increase significantly when angry. When a person is angry, he or she will experience significant sympathetic hyperexcitation, which will result in increased myocardial contraction, increased oxygen consumption, increased heart rate, and increased blood pressure. At the same time, the patient will experience a series of symptoms such as dizziness, headache, chest tightness, shortness of breath, palpitations, and discomfort in the precordial region. In addition, anger affects the endocrine system in the body and activates the renin-angiotensin-aldosterone system, leading to hyper-secretion of aldosterone, which can further lead to an increase in blood pressure. It also produces an imbalance in the homeostasis of the neurohumoral-endocrine system, which can also cause fluctuations in blood pressure.
