Factors That Cause a Hypoeffective Heart: Any factor

that decreases the heart’s ability to pump blood causes

hypoeffectivity.

Some of the factors that can decrease the heart’s ability
to pump blood are the following:

• Increased arterial pressure against which the
heart must pump, such as in severe

hypertension • Inhibition of nervous excitation
of the heart • Pathological factors that cause

abnormal heart rhythm or rate of heartbeat
• Coronary artery blockage, causing a “heart
attack” Figure 3

• Valvular heart disease
• Congenital heart disease

• Myocarditis, an inflammation of the heart muscle
• Cardiac hypoxia[1].
