Although patients typically describe stable angina as deep, poorly localized chest or arm discomfort that is exacerbated by activity or emotional stress and relieved by rest, nitroglycerin, or both, the discomfort associated with UA is more severe, occurs at rest, and is usually described as frank pain.Schoenhagen P, Ziada KM, Kapadia SR, Crowe TD, Nissen SE, Tuzcu EM.
If these arteries are narrowed or blocked, the heart does not get enough oxygen.The most recent trial, the ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes), randomly assigned 1200 patients with ACS to an early invasive strategy or a conservative strategy and found no significant differences between the groups at 1 year 90 and at 3 years 91 in the rate of the primary end point of death, MI, or rehospitalization for angina.Abstract The term acute coronary syndrome (ACS) refers to any group of clinical symptoms compatible with acute myocardial ischemia and includes unstable angina (UA), non—ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI).It has 2 components: (1) antiplatelet therapy, which reduces platelet activation and aggregation, integral steps in the formation of a thrombus after plaque disruption, and (2) anticoagulant therapy, which targets the clotting cascade to prevent the deposition of fibrin strands in the clot.PRINCIPLE-TIMI 44 Investigators Prasugrel compared with high loading- and maintenance-dose clopidogrel in patients with planned percutaneous coronary intervention: the Prasugrel in Comparison to Clopidogrel for Inhibition of Platelet Activation and Aggregation-Thrombolysis in Myocardial Infarction 44 trial.
