Which of the following is NOT a contributing factor to heart failure?

Excessive hydration is not typically considered a contributing factor to heart failure. The body's fluid balance is crucial in maintaining cardiovascular health; however, when a person is excessively hydrated, it may lead to dilution of electrolytes but does not inherently cause heart failure. Heart failure primarily arises when the heart is unable to pump effectively, often due to underlying cardiovascular issues or diseases.

On the other hand, conditions like coronary artery disease, genetic diseases, and congenital abnormalities can significantly impair heart function. Coronary artery disease leads to narrowed arteries and reduced blood flow, directly affecting cardiac performance. Genetic diseases may predispose individuals to heart problems or muscle abnormalities over time. Congenital abnormalities affect the structure and function of the heart from birth, which can lead to the development of heart failure later in life. Each of these factors contributes to the heart's overall health and its ability to function efficiently, making them relevant to heart failure development.
