A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys). It is different from a hypertensive urgency by this additional evidence for impending irreversible hypertension-mediated organ damage (HMOD).
In these situations of hypertensive emergency, rapid reduction of the blood pressure is mandated to stop ongoing organ damage. [4] In contrast there is no evidence that blood pressure needs to be lowered rapidly in hypertensive urgencies , where there is no evidence of target organ damage; over-aggressive reduction of blood pressure is not ...
The initial aim of treatment in hypertensive crises is to rapidly lower the diastolic pressure to about 100 to 105 mmHg (Incorrect - A decrease to 100mmHg from 180 would be almost a 40% decrease from baseline); this goal should be achieved within two to six hours, with the maximum initial fall in BP not exceeding 25 percent of the presenting value.
A hypertensive urgency is a clinical situation in which blood pressure is very high (e.g., 220/125 mmHg) with minimal or no symptoms, and no signs or symptoms indicating acute organ damage. [1] [2] This contrasts with a hypertensive emergency where severely high blood pressure is accompanied by evidence of progressive organ or system damage. [1]
In hypertensive urgency, there is no evidence of end organ damage resulting from the elevated blood pressure. In these cases, oral medications are used to lower the BP gradually over 24 to 48 hours. [29] In hypertensive emergency, there is evidence of direct damage to one or more organs.
Left ventricular hypertrophy. Hypertensive heart disease is the result of structural and functional adaptations [18] leading to left ventricular hypertrophy, [19] [20] [21] diastolic dysfunction, [18] [20] CHF (Congestive Heart Failure), abnormalities of blood flow due to atherosclerotic coronary artery disease [18] and microvascular disease, [10] [19] and cardiac arrhythmias.

While the golden hour is a trauma treatment concept, two emergency medical conditions have well-documented time-critical treatment considerations: stroke and myocardial infarction (heart attack). In the case of stroke, there is a window of three hours within which the benefit of thrombolytic drugs outweighs the risk of major bleeding.
Listed below are conditions that constitute a possible medical emergency and may require immediate first aid, emergency room care, surgery, or care by a physician or nurse. Not all medical emergencies are life-threatening; some conditions require medical attention in order to prevent significant and long-lasting effects on physical or mental ...
