Summary of "Acute heart failure in rabbits by avocado leaf poisoning."

The aim of this paper was to report an outbreak of avocado poisoning in rabbits in Salta, Argentina. Fourteen rabbits died of congestive heart failure within 30 h of ingesting fresh avocado leaves from pruned trees. They showed clinical signs of respiratory and cardiac distress. Full necropsies of four rabbits were performed and samples were collected for histopathology. The gross pathological observation included pleural and pericardial effusion, pulmonary oedema, slight ascites; the hearts appeared flabby and markedly pale. In addition, the stomach content consisted mostly of green feed with large amounts of avocado leaves. Epidermal fragments of Persea americana were identified by microhistological analysis of gastric content to get most efficiently to a correct diagnosis. Histopathological examination revealed degeneration and necrosis of myocytes and a mononuclear cellular infiltration mainly involving the myocardium and, to a lesser extent, the liver, lung and kidneys. Our observations indicate that avocado leaves should be avoided in the green diet of rabbits.

Medical and Biotech [MESH] Definitions

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.

A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.

Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.

Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
