Application of Evidence-Based Medicine to Cardiovascular Clinical Care:

My research has centered on evaluating the use of evidence-based medicine on the diagnosis and management of patients with caridovascualr disease. I have sought to identify areas in clinical medicine with significant variation in care, use various methodologies to obtain and analyze the different strategies and outcomes, and provide a sound base of evidence on which to recommend clinical decisions. The methodologies include primary data collection, secondary data analysis, synthesis of results of various studies into clinically useful forms such as meta-analyses and cost-effectiveness analysis, establishing clinical practice guidelines and data standards, and promoting quality assurance and improvement. Specifically, I have pursued the detection of cardiac sources of emboli by echocardiography in patients at high risk for stroke, such as patients with atrial fibrillation or prior stroke, and in improving application of this information to patient care. Current projects include evaluating the utility of echocardiographic diastolic parameters, studying ways to increase the application of guideline-proven therapies in pateitns with acute myocardial infarction, and establishing quality performance standards for noninvasive cardiac imaging.
