この練習問題は、前記事のビデオと回答を見てからの方がわかりやすいかもしれません。
Q: Summarize the lecture in one minute.
Answer: This video talks about heart diseases and heart attacks, caused by clogged coronary arteries (LCA and RCA), which provide blood to the heart. A plaque contains lipids; fat, cholesterol, and dead while blood cells, which obstruct the blood flow, will build up on the wall of the arteries, which called atherosclerosis, narrowing the vessels supplying blood.
The restriction of blood flow, ischemia, a deprivation of blood flow and oxygen downstream causes heart disease or coronary artery disease. This is one of the causes of a heart failure, when the heart being unable to function.
The symptom of ischemia is strangling chest pain, angina pectoris, that occurs when a plaque keeps growing and ruptures by turbulent blood flow, lipids, thrombogenic material, that exposed to blood immediately forms clot, obstructing the blood vessel. The cells downstream will no longer get oxygen and die, infarction is a primary cause of a heart attack.
A cardiac arrest, not a heart attack or a heart failure, is dying, or stopping of the heart. People may survive a heart attack, but they will not a cardiac arrest.
