6.1.3. HF With Preserved or Reduced Ejection Fraction
➤ CAD is the most common cause of HF in the United States and has
a pivotal role in the development and progression of both HF with
preserved ejection fraction and HF with reduced ejection fraction.
Management of patients with CCD and HF with preserved ejection
fraction and HF with reduced ejection fraction should follow
associated guideline recommendations for revascularization and
HF, as well as sections in this guideline: Section 4.2, "Guideline-
Directed Medical Therapy," Section 4.3, "Medical Therapy to Prevent
Cardiovascular Events and Manage Symptoms," and Section 5,
"Revascularization."
