I want to find all patients with a diagnosis of ischemic heart disease and an abnormal echocardiogram within any time frame, with a specificity scale of 0 and a panel accuracy scale of 100. The first panel will search for the diagnosis of ischemic heart disease in the circulatory system category, while the second panel will search for abnormal findings on diagnostic imaging of other body structures, specifically abnormal echocardiograms. The query is not inverted, meaning it will return only patients with both conditions.
