Official Title: A Safety and Feasibility Study of Transcoronary Myocardial Buffering and Cooling During Primary Coronary Angioplasty to Reduce Myocardial Reperfusion Injury in Acute Myoca
Brief Summary: Patients with heart attacks caused by blocked coronary arteries are usually treated with a technique called primary angioplasty. Although this treatment is very successful it can result in damage to the heart muscle when the artery is opened due to reperfusion injury. Cooling the entire body has been shown to reduce heart muscle damage during heart attacks in some patients but not in others, however it is uncomfortable due to the shivering, expensive and can result in delays in opening the blocked artery. We are investigating a simpler way to cool the heart muscle directly using cooled fluid passed through the catheter without the shortcomings of entire body cooling. This pilot will address safety and feasibility considerations.
