심장질환 치료의 획기적인 변화
Good evening? Millions of Americans with heart problems have them. Stents 심혈관 확장용 도구 to open up blocked arteries. Many of those millions we learned today may not need them. A major study from the leading cardiologists 심장 전문의 concludes the drugs can be just as good keeping patients alive as the celebrated 유명한, 저명한 stent. The current President of the American College of Cardiology calls this study a blockbuster 큰 영향을 주는 것. And it may well ~하는 것은 당연하다 have major implications 밀접한 관계, 영향 for the treatment of heart disease. So we start tonight with ABC’s John McKenzie.
It was blockbuster news and many of the country’s top cardiologists huddled <떼지어> 몰리다 to hear the details. 13 years after doctors started using stents to prop open ~로 받쳐서 열다 blocked arteries, researchers had finally tested a common assumption 가정, 추정. If stents allow more blood flow to the heart, they should equal ~과 같다 fewer heart attacks in the future. But that assumption is wrong.
Researchers followed more than 2200 patients, most of the men, who had a blocked artery and chest pains when they exercise. Half got aggressive 적극적인 drug therapy 요법, 치료, high doses 복용량 of statins 획기적인 콜레스테롤 강하제 to reduce cholesterol. Medication to lower blood pressure. Daily aspirin to reduce blood clots <피 등의> 엉긴 덩어리. The other half got that same aggressive drug therapy plus a stent. After four and a half years, the rate of heart attacks and death in the two groups was the same.
The key message from these findings is when it comes to ~에 대해서 말하자면 getting a stent, most patients do not need to rush 서두르다, they can afford to give medications a chance to work. Some doctors estimate that may mean hundreds of thousands of Americans each year may now be able to do without this all too common procedure. John McKenzie, ABC News,
