The aim of this study is to evaluate the effects of coronary thrombus modification on preventing the microvascular damage associated with primary percutaneous coronary intervention (PCI), and to limit the associated myocardial damage assessed by myocardial salvage index after 3 months. Furthermore, the project will evaluate coronary microvascular damage assessed invasively using both continuous and bolus thermodilution before and after stent implantation. In addition, the project will evaluate the diagnostic ability and associations of pre-stenting invasive physiological measurement to cardiac magnetic resonance imaging measurements.
