Low molecular weight heparin (dalteparin) compared to unfractionated heparin as an adjunct to rt-PA (alteplase) for improvement of coronary artery patency in acute myocardial infarction—the ASSENT Plus study

Abstract

In alteplase treated AMI adjunctive dalteparin for 4-7 days seems to reduce the risk of early coronary artery occlusion and reinfarction. However, early after cessation of treatment there is a raised risk of events, which might eliminate any long-term gains.
