What are the two types of heart failure?

The two types of heart failure are systolic and diastolic dysfunction. Systolic dysfunction occurs when the heart's ability to contract is impaired, leading to reduced ejection fraction and inadequate blood flow to the body. This is often due to conditions such as ischemic heart disease or cardiomyopathy. Diastolic dysfunction, on the other hand, refers to the heart's inability to relax properly and fill with blood during the diastolic phase. This can lead to increased filling pressures and symptoms of heart failure even in patients with a normal ejection fraction.

While other options mention various conditions associated with heart failure, they do not accurately categorize heart failure types in the manner that systolic and diastolic dysfunction do. It's important to understand these two classifications as they guide treatment options and management strategies for individuals with heart failure.
