20. Common Heart Problems Heart Valve Problems
Stenotic Valve- hardened valve restricting blood flow
Regurgitation- “leaky valve” valve does not close tightly
Heart Chamber Problems
Systolic Heart Failure- weak or enlarged heart causing left ventricle to lose its ability to contract.
Diastolic Failure- the chamber becomes stiff and loses its ability to relax and fill with blood
Artery Problems
Coronary Artery Disease- arteries supplying blood to heart become hardened and narrowed.
Rhythm Problems
Arrhythmias- irregular heartbeat due to disruption of normal electrical rhythm of the heart.
Circulatory Problems
Heart Attack- reduced blood flow to the heart causing damaged heart muscle.
Stroke- reduced blood flow to the brain causing damaged brain cells.
