| Study acronym | ULYSIS |
| Study objectives | The optimal treatment strategy in patients with Acute Myocardial Infarction (AMI) is immediate restoration of coronary blood flow. Although thrombolytic therapy is the most widely used therapy, Percutaneous Coronary Intervention (PCI) is the treatment of choice in AMI patients, however, its widespread use is hampered by limited availability of specialised facilities and trained staff. There is a need for simpler and low-risk methods for effective recanalisation of thrombosed arteries that can be initiated early in the disease process. Recently, the application of ultrasound in combination with thrombolytic agents was found to enhance thrombus dissolution in vitro and in vivo. In vivo studies using thrombo-occlusive canine and rabbit models demonstrated that Ultrasound Contrast Agents (UCAs) enhance this thrombus dissolving effect of ultrasound, resulting in higher recanalisation rates of occluded arteries. Hypothesis: Under influence of ultrasound, UCAs enhance dissolution of thrombus in patients with acute ST-elevation myocardial infarction premedicated with aspirin and clopidogrel. |

| Health condition(s) or problem(s) studied | Acute myocardial infarction |
| Intervention | After having received 150 - 325 mg aspirin and a loading dose of 300 mg clopidogrel, patients will be randomised to: 1. Ultrasound application with infusion of an ultrasound contrast agent, or 2. Control (infusion of saline without ultrasound application). Immediately after ultrasound application, catheterisation will be performed. |
