This is a calorie controlled, heart-healthy eating plan that does not require any special foods. Hypertensive emergency is severely elevated blood pressure (BP) associated with new or progressive target organ dysfunction. This requires treatment with a titratable shortacting intravenous (IV) antihypertensive agent, while severe HTN with no acute end-organ damage (ie, hypertensive urgency) is usually treated with oral antihypertensive agents. Hypertensive emergencies are usually the result of a rapid rise in BP, which may develop in children regardless of whether they have been previously diagnosed with hypertension. If a person with a blood pressure of 180/120 mm Hg or higher also has new symptoms especially those related to the eye, brain, heart, or kidney this is known as a hypertensive emergency. Rapid onset, 1. Bookshelf In addition to history and physical examination findings, target organ involvement should be evaluated using tests that can be done quickly: ECG and chest x-ray to evaluate for heart failure and ventricular hypertrophyif possible, an echocardiogram, which is much more accurate, Urinalysis to screen for renal parenchymal disease, Serum electrolytes, blood urea nitrogen (BUN), and creatinine to screen for kidney dysfunction (elevated creatinine) and adrenal abnormalities (low potassium), Complete blood count to screen for hemolytic-uremic syndrome Hemolytic-Uremic Syndrome (HUS) Hemolytic-uremic syndrome (HUS) is an acute, fulminant disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney injury.
