The difference between a heart attack and an angina attack is the extent to which the affected artery is blocked. With angina, blood flow is typically restricted or lowered, allowing some blood to continue through to the heart. In the event of a heart attack, the artery is usually completely...
Anomalous coronary artery.In their normal position, the coronary arteries lie on the surface of the heart. On occasion, in the course of a part, the artery can dive into the heart muscle itself. When the heart muscle contracts, it can temporarily kink the artery and cause angina. Again, ...
Mild heart attack symptoms might only occur for two to five minutes then stop with rest. A full heart attack with complete blockage lasts much longer, sometimesfor more than 20 minutes. What is mild heart attack? In this type of heart attack, blood flow through one of the coronary arteries...
A myocardial infarction (myo=muscle + cardium=heart+ infarction=death) or heart attack occurs when the sudden blockage of a coronary artery, usually because ofblood clot, causes damage and death to heart muscle. The heart is an electric pump with the purpose of sending oxygen-rich blood throug...

Cholesterolplaque gradually builds on the inner lining of a coronary artery, narrowing its diameter and decreasing the amount of blood that can flow past the blockage. If the heart is asked to do more work and pump harder and faster, enough oxygen may not be able to be delivered beyond the...
Call for emergency services.If the symptoms pass quickly, there may have been atransient ischemic attack(TIA) or a "mini stroke." It's a brief blockage of blood flow to your brain that often comes before a stroke.It may last for only a few minutes.Don’t ignore this warning sign. ...

Sometimes a blood clot can form at the narrowed area of the coronary artery. This can quickly block the blood flow through this artery. Once there is a severe or complete blockage, the heart muscle that does not receive enough oxygen-rich blood can then die. This portion of dead heart mus...
