People with an average age of 62 years, who have moderate to severe degrees of angina (grading by classesII, III, and IV) have a 5-year survival rate of approximately 92%.Worsening angina attacks, sudden-onset angina at rest, and angina lasting more than 15 minutes are symptoms of unstable angina (usually grouped with similar conditions as the acute coronary syndrome). As these may precede a heart attack, they require urgent medical attention and are, in general, treated in similar fashion to myocardial infarction.03三、WordsAnemia 贫血Heart failure 心衰Impending [尤指不幸]即将发生的5-year survival rate 5年生存率Sudden-onset 突发的Unstable angina 不稳定心绞痛Acute coronary syndrome 急性冠脉综合症Myocardial infarction心肌梗死·END·兰大Freescience未经允许  禁止转载
