Drug-coated stents

 I posted this article after reading it because it affected me personally. My stepfather has lived pretty hard, which has included heavy drinking, smoking and eating a lot of fatty red meats. He had a heart attack about 15 years ago at the age of 32. He started to live a healthier life after the heart attack but within a few years, the unhealthy lifestyle had come back. I'm interested to know whether the drug-coated stents of today can be effective despite someone who lives like my stepfather. If you're interested in reading about this newer version of the stent, please read the following article.
