Key result
The abstract outlines an aim to quantify cardiac tissue replacement, collagen deposition, and pro-inflammatory cytokines in ethanol-drinking rats, but reports no results.
Why the study?
Chronic ethanol abuse causes toxic effects including alcoholic cardiomyopathy, but cardiac tissue replacement, collagen deposition, and proinflammatory cytokines needed quantification in spontaneous drinking models.
Does chronic ethanol consumption alter cardiac tissue replacement, collagen deposition, and inflammation in the left ventricle of adult male rats?
Does chronic ethanol consumption alter cardiac tissue replacement, collagen deposition, and inflammation in the left ventricle of adult male rats?
In a rat model of spontaneous ethanol drinking, chronic alcohol consumption induced myocardial fibrosis and increased apoptosis without altering systemic IL-1 or TNF-α levels.

Chronic ethanol induces myocardial fibrosis and apoptosis in rats without cytokine changes; leaves open human relevance.
When speaking of pathologies caused or aggravated by the constant ingestion of ethanol, people with liver and central nervous system diseases soon come to mind, however, the acute intake of large amounts of ethanol and chronic abuse induce toxic effects in the majority of tissues. The heart is highlighted, since alcoholic cardiomyopathy (AC) has prevalence among alcoholics of 23 to 40% and occurs more frequently in men than in women. AC is characterized by dilation and poor contraction of one or both ventricles in the presence of increased ventricular wall thickness, along with a long history of ethanol abuse and no other cause identified. Our aim is to quantify the rate of cardiac tissue replacement, collagen fiber deposition and pro inflammatory cytokines in the left ventricle myocardium of volunteer ethanol drinking rats.

Camargo et al. (2021) studied Alcoholic cardiomyopathy. Ethanol drinking was evaluated on Rate of cardiac tissue replacement, collagen fiber deposition and pro inflammatory cytokines in the left ventricle myocardium. The abstract outlines an aim to quantify cardiac tissue replacement, collagen deposition, and pro-inflammatory cytokines in ethanol-drinking rats, but reports no results.
