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 mmHg or a diastolic blood pressure over 120 mmHg, accompanied by signs of organ damage. Common symptoms may include severe headache, chest pain, shortness of breath, or changes in vision. Immediate medical treatment is crucial in a hypertensive emergency to prevent damage to vital organs such as the heart, brain, and kidneys. Treatment often involves intravenous medications to quickly lower blood pressure and stabilize the patient. Regular monitoring and follow-up care are essential to manage blood pressure effectively.
