Women are often sent home， thinking they are OK． Yet many are at high risk for a heart attack． In USA， researchers say as many as three million women could have coronary microvascular syndrome． The Journal of the American College of Cardiology recently published findings from a government study． The study is called the Women39。s Ischemia Syndrome Evaluation(婦女缺血綜合征的評價 )， or WISE． Ischemic heart disease involves restricted blood flow． The study began in nieen niysix and involves more than nine hundred women who suffer chest pain． Researchers found large blockages in major arteries in about onethird of the women． The other women looked clear on an angiogram(血管造影 )test for blockages． But the researchers say half of them had enough buildup in small arteries to cause a heart attack within five years． In men and women both， the most mon warning sign is chest pain． But women are more likely to experience other mon signs like shortness of breath， a sick stomach and pain in the back or jaw． A cold sweat and feeling lightheaded can also mean a heart attack． 63.
