CHF can result from which cardiac event?

Heart failure, or congestive heart failure (CHF), can be a consequence of myocardial infarction (MI) because an MI results in damage to the heart muscle, impairing its ability to pump effectively. When a portion of the heart muscle dies due to the lack of oxygenated blood during a heart attack, the heart's overall function can decline, leading to CHF.

In essence, an MI reduces the heart's efficiency and can lead to fluid backup in the lungs and other symptoms typical of CHF. Early identification and treatment of MI are vital to prevent or mitigate this progression to heart failure. Other events like stroke, arrhythmia, or cardiac arrest can also impact heart function but typically do not lead directly to CHF in the same manner as an MI does, as they might cause different types of complications or conditions.
