Hypertension is a very common disease with great harm. What is the hypertension crisis? Let's listen to the experts' introduction.
Hypertension crisis is a kind of clinical syndrome. It is mainly due to the hyperactivity of sympathetic nerve function and excessive secretion of catecholamine that causes the short-term and strong spasm of arterioles, and the sudden rise of peripheral vascular resistance, which leads to the sharp rise of blood pressure in a short period of time.
The main clinical manifestations are the sudden rise of blood pressure, mainly the rise of systolic blood pressure, accompanied by headache, dizziness, fidgety, pale face, dry mouth, palpitation, tinnitus, hyperhidrosis, nausea, vomiting, blurred vision or temporary blindness, frequency of urination, urgency of urination and other symptoms. Severe patients may have angina, brain edema or renal dysfunction. These symptoms usually last for a short time. Hypertension crisis can occur in any type of hypertension. Systolic blood pressure is more than 26.7 kPa (200 mmHg) and diastolic blood pressure is more than 17.3 kPa (130 mmHg).
There are many factors to induce hypertension crisis, such as mental stimulation, mood sudden change, overwork, climate change, endocrine disorders, etc. The mortality rate of hypertension crisis is very high. In the past, there was no effective antihypertensive drug treatment. The one-year mortality rate was 90%, and the five-year mortality rate was 99%. Even if the effective treatment was used now, the one-year mortality rate was still 25%, and the five-year mortality rate was still 50%. Hypertension crisis mainly died of hypertension, heart disease, acute heart failure or acute renal failure.
