Abstract

Pigs were made copper (Cu)-deficient to evaluate cardiac function and pathology, and electrocardiography. Fifteen-day-old pigs were fed a Cu-restricted diet over an 8 wk period and compared to Cu-adequate diet-fed pigs. Cardiac effects were examined concerning gross morphometry and ultrastructure, echocardiography, and electrocardiography, as well as serum cholesterol levels. The Cu-restricted diet-fed pigs exhibited a marked deceleration of growth and lower hematocrit, hemoglobin, and liver and serum Cu concentrations compared to the Cu-adequate diet-fed pigs. The Cu-restricted diet-fed pigs developed a significantly greater heart weight:body weight ratio, along with greater diastolic measures of ventricular wall and internal dimension relative to body weight. Electrocardiography in the Cu-restricted diet-fed pigs revealed one instance of electrical alternans and an intraventricular conduction disturbance and several instances of T-wave inversion. The Cu-restricted pigs also displayed a prolonged QT interval at the closure of study. Increased mitochondrial volume density and mitochondria:myofibril volume density ratio were observed in the Cu-restricted pig electron micrographs along with excessive lipid and glycogen inclusion ...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
