Heart Attack

A heart attack occurs when a blocked artery prevents oxygen-rich blood from reaching a section of the heart. If the blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die. The longer a person goes without treatment, the greater the damage.

Symptoms of a heart attack may be immediate and intense. More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. Unlike with sudden cardiac arrest, the heart usually does not stop beating during a heart attack.

Cardiac Arrest

Sudden cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia).

With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs. Seconds later, a person loses consciousness and has no pulse. Death occurs within minutes if the victim does not receive treatment.



Systolic dysfunction (or systolic heart failure) occurs when the heart muscle doesn’t contract with enough force, so there is less oxygen-rich blood that is pumped throughout the body.

Diastolic dysfunction (or diastolic heart failure) occurs when the heart contracts normally, but the ventricles do not relax properly or are stiff, and less blood enters the heart during normal filling.

A calculation done during an echocardiogram, called the ejection fraction (EF), is used to measure how well your heart pumps with each beat to help determine if systolic or diastolic dysfunction is present. Your doctor can discuss which condition you have.
