Open-angle glaucoma. Chronic open-angle glaucoma is the most common form of glaucoma. The open drainage angle of the eye can become blocked leading to gradual increased eye pressure. If this increased pressure results in optic nerve damage, it is known as chronic open-angle glaucoma.
Acute tubular necrosis. Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys. ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI. Common causes of ATN include low blood pressure and use of nephrotoxic drugs.
Acute coronary syndrome. Overview. Acute coronary syndrome is a term used to describe a range of conditions associated with sudden, reduced blood flow to the heart. One condition under the umbrella of acute coronary syndrome is myocardial infarction (heart attack) â when cell death results in damaged or destroyed heart tissue. Even when acute coronary syndrome causes no cell death, the reduced blood flow alters heart function and indicates a high risk of heart attack.
