Heart failure can be categorized into different stages, with minimal or early heart failure often referred to as Stage B. Here are some key points about Stage B heart failure:

- Stage B Heart Failure: This stage involves changes in heart function but without symptoms. Many people are unaware they are in this stage unless changes are discovered by a doctor.
- Ejection Fraction (EF): People in Stage B often have an EF below 40 percent. EF measures how much blood the heart pumps out with each heartbeat.
- Causes: Changes in the left ventricle, damage from conditions like myocarditis, exposure to toxic chemicals, medications, or a heart attack, and faulty valves can contribute to Stage B heart failure.
