A hypertensive emergency is a severe increase in blood pressure that can lead to serious health complications. It is defined as a systolic blood pressure over 180 mm Hg or a diastolic blood pressure over 120 mm Hg, accompanied by signs of organ damage. Common symptoms may include severe headache, chest pain, shortness of breath, or neurological changes. Immediate medical intervention is crucial in a hypertensive emergency to prevent damage to vital organs such as the heart, kidneys, and brain. Treatment often involves intravenous medications to quickly lower blood pressure and stabilize the patient. Regular monitoring and follow-up care are essential to manage underlying hypertension effectively.
