What it is

920 patients referred for coronary angiography at four sites (Cleveland Clinic Foundation; Hungarian Institute of Cardiology, Budapest; University Hospitals of Zurich and Basel; VA Medical Center, Long Beach). Thirteen clinical attributes (age, sex, chest pain type, resting blood pressure, cholesterol, fasting blood sugar, resting ECG, maximum heart rate, exercise angina, ST depression, ST slope, major vessels, thalassemia) and diagnosis_severity (0 = no disease, 1–4 = increasing severity). site says where each patient was seen.

How to use it

Train on some sites and test on another to see how a model travels between hospitals. Many values are missing outside Cleveland (left blank).
