KF：你怎么看药物、支架手术和旁路手术的作用？
例如，冠状动脉支架手术在国外平均费用为2万美元（包括诊断、住院和旅行费用），而美国医保花费为2万1千美元。
Coronary bypass surgery, for example, costs on average about $20,000 overseas (including various doctor and hospital fees and travel expenses), while the average Medicare reimbursement is $21,000.
CE：对于已患心脏病的人来说，支架手术或旁路手术还是能救命的，但是，有90%的研究证明支架手术或旁路手术并不能阻止未来的心脏病发作或延长寿命。
CE: Admittedly in the midst of a heart attack a stent or bypass may be live saving, however, for the remaining 90% studies confirm that they do not prevent future heart attacks or prolong life.
