Hypertension caused by kidney disease is called renal hypertension. The blood pressure of patients with renal hypertension is generally higher than that of those with primary hypertension. However, these patients can exhibit any range of blood pressure types. Their blood pressure might be in stage 1, meaning the systolic pressure is between 140 to 160 mmHg. It could also reach stage 3, where the systolic pressure exceeds 180 mmHg. In cases of heart failure, the patient's blood pressure might even reach 220 or 240 mmHg, though such extreme cases are relatively rare.

Normal blood pressure, high blood pressure, and low blood pressure ranges.

Normal adult systolic blood pressure is between 90-139mmHg, and diastolic pressure is between 60-89mmHg. When the systolic pressure exceeds 140mmHg and the diastolic pressure exceeds 90mmHg, this condition is medically referred to as hypertension. When the systolic pressure is below 90mmHg and the diastolic pressure is below 60mmHg, this condition is medically referred to as hypotension. Regardless of whether it is hypertension or hypotension, it often causes symptoms in patients, such as headache, dizziness, and fatigue. Therefore, whether it is hypertension or hypotension, one should visit the hospital's department of cardiology for a formal examination. The doctor will assess the situation on-site to determine if treatment is necessary and how to administer it.

Difference between hypertensive crisis and hypertensive encephalopathy

Hypertensive crisis, now referred to as hypertensive emergency, includes hypertensive encephalopathy. It mainly refers to cases where, under certain triggers, the blood pressure of patients with primary or secondary hypertension suddenly or significantly rises, typically exceeding 180/120 mmHg, accompanied by progressive failure of critical target organs such as the heart, brain, and kidneys. Hypertensive emergencies include hypertensive encephalopathy, cerebral hemorrhage, cerebral infarction, acute heart failure, acute coronary syndrome, aortic dissection, etc. Hypertensive encephalopathy is characterized by symptoms caused by hypertension, such as headache, blurred vision, nausea, vomiting, and severe edema of the head.

Difference between hypertensive encephalopathy and malignant hypertension

The difference between hypertensive encephalopathy and malignant hypertension can be discerned from their names, indicating they are different conditions. Hypertensive encephalopathy refers to a condition where blood pressure rises sharply in a short period, with diastolic pressure exceeding 120 mmHg and systolic pressure exceeding 200 mmHg. This dramatic increase in blood pressure causes cerebral vasospasm and increased cerebral perfusion pressure, leading to various manifestations of cerebral edema, primarily severe headache, nausea, vomiting, seizures, and even brain herniation. The emphasis is on the rapid rise in blood pressure over a short term and its impact on the brain, specifically cerebral edema. Malignant hypertension also involves a rapid increase in blood pressure to extremely high levels over a short period. However, the focus of malignant hypertension is on the impact on multiple organs throughout the body, including the brain, but also severely affecting the heart, potentially causing acute left heart failure and pulmonary edema. In the kidneys, it can lead to acute renal failure, characterized by reduced urine output or anuria. Thus, malignant hypertension emphasizes the effects on multiple vital organs, whereas hypertensive encephalopathy focuses primarily on the impact on the brain and central nervous system. Hence, there are some distinctions between the two conditions.

The difference between hypertensive crisis and hypertensive encephalopathy

Both hypertensive encephalopathy and hypertensive crisis involve a rapid increase in blood pressure, symptoms of headache, restlessness, nausea and vomiting, palpitations, shortness of breath, and blurred vision, with systolic pressure increasing to 200 mmHg and diastolic pressure to 120 mmHg, typically presenting similar clinical blood pressure readings. The main difference between the two is that hypertensive encephalopathy is based on excessively high blood pressure in patients with severe hypertension. Furthermore, hypertensive encephalopathy can lead to clinical signs of cerebral edema and increased intracranial pressure, whereas hypertensive crisis occurs when blood pressure suddenly rises over a short period, causing symptoms due to excessive secretion of catecholamines driven by increased sympathetic nervous excitement.

What is the blood pressure for gestational hypertension?

Pregnancy-induced hypertension refers to a series of pathophysiological changes caused by elevated blood pressure in women during pregnancy. It is a severe complication of pregnancy that can have serious effects on both the mother and the fetus. The diagnostic standard for hypertension during pregnancy is the same as in non-pregnant periods, that is, a blood pressure greater than 140/90mmHg can be diagnosed as pregnancy-induced hypertension. However, pregnancy-induced hypertension can be classified based on whether it is combined with other conditions, as well as the severity of the condition. Depending on the severity, pregnancy-induced hypertension can be divided into categories such as gestational hypertension, pre-eclampsia, eclampsia, chronic hypertension, and chronic hypertension with superimposed pre-eclampsia. These classifications are mainly based on the severity of the condition, and it is essential to treat pregnancy-induced hypertension with standardized care.
