Toxic cardiomyopathies.

A toxic cardiomyopathy caused by Cassia occidentalis. II. Biochemical studies in poisoned rabbits.

Chemical cardiomyopathies: the negative effects of medications and nonprescribed drugs on the heart.

The heart is a target of injury for many chemical compounds, both medically prescribed and not medically prescribed. Pathophysiologic mechanisms underlying the development of chemical-induced cardiomyopathies vary depending on the inciting agent, including direct toxic effects, neurohormonal activation, altered calcium homeostasis, and oxidative stress. Numerous chemicals and drugs are implicat...

Chemotherapy induced cardiomyopathy: an overview, imaging features, and future prospective

Content organisation Cardio toxic effect of chemotherapy is a well-recognised problem in cancer patients. Cardio toxicity depends on multiple predisposing factors, specific components of the chemotherapy regimen, length of treatment, and dosage. We will present the spectrum of most common cardiotoxic chemotherapy agents and their combinations, specific effects on the myocardium, and imaging fea...

MRI to Evaluate Cardiomyopathies and Inflammatory Cardiac Disease

Background. Earlier classifications of cardiomyopathies described them in terms of their morphologic characteristics (dilated, hypertrophic) or functional consequences (restrictive). The current classification of cardiomyopathies has recently been updated [1] as diseases of the myocardium that are associated with mechanical and/or electrical dysfunction that exhibit inappropriate ventricular hy...

Cardiac lesions induced by chemicals.

Chemically induced cardiomyopathies are frequently the consequences of a cardiac metabolic imbalance brought about by exaggerated functional affects. The infarctlike lesions induced by adrenergic beta-receptor stimulants and the vasodilating antihypertensives serve as examples of this phenomenon. Direct cardiotoxic mechanisms not related to cardiovascular functional effects are responsible for ...
