The present invention relates to compounds for treatment that protects the endothelium, prevents pathologic thrombus formation in the microcirculation and preserves platelet number and function and thus may be related to treatment or prevention of ischemic events in patients with cardiovascular disease. The present invention is particularly useful for patients having or being at increased risk of development of an ischemic event such as an acute myocardial infarction and/or no-reflow phenomena and/or ischemia-reperfusion injury by administration of agent(s) modulating and/or preserving endothelial integrity. The compounds may be administered in combination with standard treatment of acute cardiovascular ischemic events such as Platelet inhibitors such as aspirin (ASA), Thienopyridins, GPIIb/IIIa inhibitors), Parenteral anticoagulants such as unfractioned heparin (UFH), bivalirudin, enoxaparin, and fondaparinux, Verapamil, Adenosine, Sodium nitroprusside, Nitroglycerin, Epinephrine, Beta-blockers and surgical methods such as percutaneous coronary intervention (PCI), PCI with thrombus aspiration, PCI with stents.
