South Beach Heart Health Revolution - by Agatston - Notes

Calcium score - Also called Agatston score, measures the amount of calcified plaque inside the coronary arteries. Higher the calcium score, the higher the chance of heart attack. Excellent predictor of future heart attack risk.

Computed tomography (CT) or electron beam tomography (EBT) - used for imaging heart. Scans provide a calcium score?

Atherosclerosis - When artery walls gradually filled with plaque (cholesterol, inflammatory cells, scar tissue). Different kinds of plaque. Heart attack caused when soft cholesterol rich plaque bursts, resulting in blood clot. Blood clot blocks blood flow to heart. News to me. I thought plaque, not a blood clot, that caused artery blockage and heart attack. But this clot model makes sense, given sudden nature of heart attack. A slowly developing plaque blockage should give the heart time to grow collateral vessels.

Better model of heart attack - Heart attack not caused by plaque blockage in the tube of the vessel (old school). The culprit is plaque depositing in the inner lining of vessel walls, like pimple filled with cholesterol. When pimples bursts, an injury site is created. To heal the injury, a clot will form. If the clot is big enough, it blocks the artery, causing heart attack.
