One of the Three Types of HF Involves Systolic Dysfunction

One of the three types of HF involves systolic dysfunction. Potential causes of this most common form of HF include:

A) Myocardial ischemia and injury secondary to myocardial infarction (MI)
B) Inadequate relaxation and loss of muscle fiber secondary to valvular dysfunction
C) Increased demands of the heart beyond its ability to adapt secondary to anemia
D) Slower filling rate and elevated systolic pressures secondary to uncontrolled hypertension
