Acute decompensated heart failure/Acute heart failure Is a sudden worsening of the signs and symptoms of heart failure. See heart failure for symptoms. Symptoms include: breathlessness after activity or at rest, feeling tired most of the time and finding exercise exhausting, swollen ankles and legs. Some people also experience other symptoms, such as a persistent cough, a fast heart rate, and dizziness. Acute kidney injury Is sudden damage to the kidneys that causes them to not work properly. It can range from minor loss of kidney function to complete kidney failure. AKI normally happens as a complication of another serious illness. Angiotensin II receptor blockers Medications that block the action of angiotensin II by preventing angiotensin II from binding to angiotensin II receptors on the muscles surrounding blood vessels. As a result, blood vessels enlarge (dilate) and blood pressure is reduced.
