Acute kidney injury dehydration), low blood pressure, heart failure (leading to cardiorenal syndrome), liver cirrhosis and local changes to the blood vessels supplying the kidney. The latter include renal artery stenosis, or the narrowing of the renal artery which supplies the kidney with blood, and renal vein thrombosis, which is the formation of a blood clot in the renal vein that drains blood from the kidney. Intrinsic AKI refers to disease processes which directly damage the kidney itself. Intrinsic AKI can be due to one or more of the kidney's structures including the glomeruli, kidney tubules, or the interstitium. Common causes of each
Left anterior descending artery the right aortic sinus. In 78% of cases, it reaches the apex of the heart. The LAD gives off two types of branches: "septals" and "diagonals". The artery supplies the anterolateral myocardium, apex, and interventricular septum. The LAD typically supplies 45-55% of the left ventricle (LV) and is therefore considered the most critical vessel in terms of myocardial blood supply. The "widow maker" is an alternate name for the anterior interventricular branch of the left coronary artery. The name "widow maker" may also apply to the left coronary artery or severe occlusions to that artery. This term is used because
