Why does alcohol make heart muscles weak?

Alcohol can weaken heart muscles primarily due to its toxic effects on cardiac cells and its impact on overall cardiovascular health. Chronic consumption can lead to conditions like alcoholic cardiomyopathy, where heart muscle becomes dilated and loses its ability to contract effectively. Additionally, alcohol can disrupt the balance of electrolytes and hormones that regulate heart function, leading to increased blood pressure and irregular heart rhythms. Over time, these factors contribute to diminished heart strength and efficiency.
