Q: cardiac MRI shows heart attack

asked by: DoctorQuestion on March 30th, 2009

Pre-op testing I had an ECG which came back abnormal, then I had a stress test, came back abnormal, showed that I may have had a heart attack. Visited a cardiologist, had an angiogram, no blockage. Follow-up with an ecco cardiagram and a cardiac MRI, confirmed I had a heart attack. Lower Apex of the heart does not have blood flow. I had an ECG in 2005 and it was normal, so this had to have occured between Fall 2005 and Winter 2008. The doctors are stumped, they say I should go on coumadin daily for the rest of my life. For now I am on a 325 coated aspirin.
How can I have a heart attack when my cholesteral and trigliceroids are normal, I have no blockage, my blood pressure is normal and I have had no trauma to the chest area?

Heart Disease and Heart Attack Answer A6192

Heart attack occurs when there is not sufficient blood flow in the coronary arteries. This condition can be caused by spasm of the coronary arteries or by blockage with embolus. Most often both factors are present in heart attack.
Once the embolus blocks the flow, collateral capillaries might be open to try to supply the affected part of the heart muscle. Within few hours, the embolus starts to degrade and usually completely disappears. That is why the embolus was not detected in your case. Once having embolus that caused heart attack, further laboratory tests are needed to check the blood coagulation status and to prevent forming other emboli.
