A large study found that vascular stents and coronary artery bridal surgery do no better to prevent heart attacks and deaths in millions of Americans than to strengthen medication and improve health habits,
according to a November 16 issue of the Wall Street Journal. This provides new insights into a major controversy in cardiology.The study is one of the largest and most detailed to suggest to date that while vascular stents and heart-bridge surgery can save the lives of heart patients, they may not be better for most chronic or stable coronary heart disease patients than changes in cholesterol-lowering drugs and other health habits. About 9.4 million Americans suffer from coronary heart disease.However, the researchers found that stent or bridge surgery was better at alleviating symptoms in patients with frequent angina than relying solely on medication and lifestyle changes.The results will intensify the already bitter debate between interventional cardiologists who perform stent surgery and preventive cardiologists who prescribe cholesterol- and blood-lowering drugs and who instruct patients to change their diet and exercise.
