What causes heart failure with reduced ejection fraction (systolic heart failure)?
There are many different problems that can cause heart failure with reduced ejection fraction. They include:
- Coronary artery disease or heart attack.
They cause blockages in your coronary arteries that limit blood flow to your heart muscle. This weakens or damages heart muscle and impairs the muscle's ability to pump.
This is a disease of the heart muscle. The heart muscle is weakened, so it can't pump properly.
- High blood pressure.
This causes elevated pressure in your arteries. The heart works harder to pump against increased pressure, which weakens the muscle.
- Aortic stenosis.
This means that the opening of the aortic valve is narrowed, which impairs blood flow. The heart works harder to pump blood through the narrowed valve, weakening the muscle.
- Mitral regurgitation.
This means that the mitral valve doesn't close properly. The increased blood volume stretches and weakens the heart muscle.
- Viral myocarditis.
This is a viral infection of your heart muscle. The infection causes inflammation in the heart muscle, which affects the heart's ability to pump.
This is an irregular heart rhythm. The irregular rhythm reduces the pumping effectiveness of the heart.
