Malignant hypertension include accelerated hypertension and malignanthypertension. So-called accelerated hypertension means that the illnessstart to progress rapidly or suddenly after several years of slowdevelopment. Common in young people under 40 years of age and older,clinically significant increase in blood pressure, and often last in26.6/17.3kPa (200/130mmHg), fundus examination of retinal hemorrhage orexudate. Malignant hypertension found in young people, diastolic bloodpressure of more than 18.6kPa (140mmHg), papilledema (ii). Now believes thatboth pathological and clinical manifestations are similar to accelerated hypertension if it is not treated, it can quickly turn into malignanthypertension. In other words, malignant hypertension is acceleratedhypertension the most severe stage of the disease and, therefore, currentlyreferred to as malignant hypertension.
Radical type malignant hypertension early also can no consciously symptoms, or only has headache, to morning heavy, and often for extreme fatigue, spirit excessive tension, and cold stimulus, menopause endocrine disorders, incentives, makes blood pressure suddenly increased, diastolic pressure over 17.3k Pa (130mmHg) above, check fundus visible retinal bleeding, and seeping or depending on nipple edema, also may appeared heart function not full of performance, as apical beat obviously, heart expanded, but to kidney function damage most highlight. Common persistent proteinuria, hematuria,casts in urine and merging small artery hemolysis, and disseminatedintravascular coagulation, hemolytic anemia may occur sometimes, that oftenprompt a critical condition.
Accelerated hypertension is a kind of clinical hypertension emergencies,though not as good as hypertensive encephalopathy is badly, but if theimmediate antihypertensive therapy, often lifethreatening. According tostatistics, oneyear survival rate is only 10%~20%, most patients die withina year. Without impaired renal function or renal impairment the lesser goodprognosis, long-term survival is possible. Etiology, course and prognosis ofmalignant hypertension, blood pressure level and fundus changes of heart,brain and kidney dysfunction is related to. Blood pressure high andimportant organs such as heart, brain and kidney impairment is severe, theprognosis is poor. In recent years due to the radical understanding ofmalignant hypertension, improvement of treatment methods and the emergenceof new drugs, the prognosis changed.
