Özet
Hypertensive emergencies are those situations that require immediate blood pressure reduction to prevent or limit damage to target organs (brain, eyes, heart, or kidney). The term malignant hypertension or hypertensive crisis may also used to refer to this category. Target organ damage occurs in syndromes such as hypertensive encephalopathy, intracranial hemorrhage, acute left ventricular failure with pulmonary edema, unstable angina pectoris, acute myocardial infarction, dissecting aortic aneurysm and eclampsia. A hypertensive emergency is not defined by and absolute pressure measurements but, instead, is contingent on the presence of relative blood pressure increases combined with injury to any of the so called target organs. In fact, a patient with low baseland pressure can present with "normal" or midy elevated pressure and be considered to have a true hypertensive emergency, if there is evidence of concurrent related central nervous system (CNS), cardiovascular, or renal dysfunction. The treatment goal in hypertensive emergency is the immediate reduction of mean arterial pressure in a controlled using improvement in the patient's condition as a guide.
