<unk>  angiography and angioplasty in acute myocardial infarction (left: RCA closed, right: RCA successfully dilated) Wellens' warning<unk>  is used primarily to open a blocked<unk>  artery and restore arterial blood flow to heart tissue, without requiring open-heart surgery. In patients with a restricted or blocked<unk>  artery,<unk>  may be the best option to re-establish blood flow as well as prevent angina (chest pain), myocardial infarctions (heart attacks) and death. Today,<unk>  usually includes the insertion of stents, such as bare-metal stents, drug-eluting stents, and fully resorbable vascular scaffolds (or naturally dissolving stents). The use of stents has been shown to be important during the first three months after<unk> ; after that, the artery can remain open on its own. This is the premise for developing bioresorbable stents that naturally dissolve after they are no longer needed. The appropriateness of<unk>  use depends on many factors.<unk>  may be appropriate for patients with stable<unk>  artery disease if they meet certain criteria, such as having any<unk>  stenosis greater than 50 percent or having angina symptoms that are unresponsive to medical therapy. Although<unk>  may not provide any greater help in preventing death or myocardial infarction over oral medication for patients with stable<unk>  artery disease, it likely provides better relief of angina. In patients with acute<unk>  syndromes,<unk>  may be appropriate; guidelines and best practices are constantly evolving. In patients with severe blockages, such as ST-segment elevation myocardial infarction (STEMI),<unk>  can be critical to survival as it reduces deaths, myocardial infarctions and angina compared with medication. For patients with either non-ST-segment elevation myocardial infarction (nSTEMI) or unstable angina, treatment with medication and/or<unk>  depends on a patient's risk assessment. The door-to-balloon time is used as a quality measure for hospitals to determine the timeliness of primary<unk> . The use of<unk>  in addition to anti-angina medication in stable angina may reduce the number of patients with angina attacks for up to 3 years following the therapy, but does not reduce the risk of death, future myocardial infarction or need for other<unk> s.
