Research Interests:
The main focus of my research is in the management of acute myocardial infarction. My focus has revolved around the use of interventional procedures such as balloon angioplasty, intra-aortic balloon pumping and other support devices for the management of patients with acute myocardial infarction. Through participating and designing a number of randomized trials, we have helped crystallize the management to sustain patency of the infarct-related coronary artery in acute myocardial infarction. Furthermore, I have conducted several large multi-center clinical trials on the use of intra-aortic counterpulsation and angioplasty to better understand the pathophysiology of interventional procedures. Another major focus has been in the area of risk stratification in acute myocardial infarction. Early observations done abroad have led me to use new cardiac markers to identify high and low risk patients. Further research in this area will integrate early and rapid triage along with monitoring of the effect of thrombolysis after reperfusion in patients. A patent in the latter category has already been issued. My continued focus in the performance of multi-center international clinical trials has allowed us to explore different treatment strategies for the management of acute myocardial infarction from an international prospective. We have also collected angioplasty data on nearly 6,000 patients from around North America to further explore international differences in the management of patients using percutaneous interventions.
