Etiology Etiology
Heart failure is caused by systemic Heart failure is caused by systemic hypertension in 75% of cases.hypertension in 75% of cases.
About one third of clients About one third of clients experiencing myocardial infarction experiencing myocardial infarction also develop heart failure.also develop heart failure.
Structural heart changes, such as Structural heart changes, such as valvular dysfunction, cause pressure valvular dysfunction, cause pressure or volume overload on the heart.or volume overload on the heart.
