How do these issues cause acute heart failure?

Heart disease and certain medical conditions can make your heart work harder than usual.

This extra effort leads to physical changes that can include:

• Enlarged heart.
• Decreased blood flow.
• Narrow blood vessels.
• Rapid or irregular heartbeat.
• Stiff heart muscles.

The changes are small at first. They start long before you experience acute heart failure symptoms. Over time, the changes get worse, making your heart work harder than it should. When your heart is no longer able to keep up, acute heart failure occurs.
