冠動脈疾患にはステント治療より心臓リハビリの運動の方が効果的

８月２９日から9月2日のスペイン・バルセロナで開催された欧州循環器学会のトピックとして注目される発表及び意見が出された。それは、現在広く行われている血管造影及びバルーンＰＴＣＡやステントという診断及び治療方法は、心臓リハビリなどで行われる運動の方がより患者に優しく、効果的であるとの多数の発表があった。ワイヤレス１２誘導負荷心電計は、日本でも認可されてご用意されています。http://homepage2.nifty.com/medicalteknika/duna/

Exercise beats angioplasty for some heartpatients•BARCELONA, Spain – Working up a sweat may be even better than angioplasty for some heartpatients, experts say.Studies have shown heart patients benefit from exercise, and some have even shown it works betterthan surgical procedures. At a meeting of the European Society of Cardiology on Sunday, severalexperts said doctors should focus more on persuading their patients to exercise rather than simplydoing angioplasties.Angioplasty is the top treatment for people having a heart attack or hospitalized with worseningsymptoms. It involves using a tiny balloon to flatten a blockage and propping the heart artery openwith a mesh tube called a stent. Most angioplasties are done on a nonemergency basis, to relievechest pain caused by clogged arteries cutting off the heart's blood supply."It's difficult to convince people to exercise instead of having an angioplasty, but it works," saidRainer Hambrecht of Klinikum Links der Weser in Bremen, Germany.Hambrecht published a study in 2004 that found that nearly 90 percent of heart patients who rodebikes regularly were free of heart problems one year after they started their exercise regimen.Among patients who had an angioplasty instead, only 70 percent were problem-free after a year.Hambrecht is now conducting a similar trial, which he expects to confirm his initial findings: thatfor some heart patients, exercise is more effective than a surgical procedure.Other experts agreed that would likely be the case.An angioplasty "only opens up one vessel blockage," said Dr. Christopher Cannon, an associateprofessor of medicine at Harvard University and spokesman for the American College ofCardiology. He was not linked to Hambrecht's research. "Exercise does a lot more than fixing onelittle problem."Among other benefits, exercise lowers bad cholesterol while raising good cholesterol, helps thebody process sugar better, improves the lining of the blood vessels and gets rid of waste materialfaster. Exercise also lowers blood pressure and prevents plaque buildup in the arteries.Previous research has estimated one third of heart disease and stroke could be prevented if patientsdid two-and-a-half hours of brisk walking every week. In the U.S., that would mean 280,000 fewerheart-related deaths every year.Joep Perk, a professor of health sciences at Sweden's Kalmar University and spokesman for theEuropean Society of Cardiology, said two thirds of heart patients in line for an angioplasty couldprobably get better benefits by regularly working up a sweat.Experts say less than 20 percent of heart patients get the recommended amount of exercise — about30 minutes of moderate activity five times a week.Perk said doctors who performed angioplasties on their patients without asking them to change theirlifestyles were ignoring the fundamental problem. "It would be like getting rid of the most troubledrust spots on a car without doing anything to stop more rust from appearing tomorrow."Still, doctors admitted that persuading patients to exercise instead of simply going in for anangioplasty, which can take less than a day, would be a tough sell."Most patients want the quick fix," Cannon said. Exercise may improve patients' hearts better thanan angioplasty, but it may also take months or even longer for patients to feel the benefits. "It's a loteasier to get your artery fixed than it is to exercise every day."____On the Net:http://www.escardio.org
