Medical data is still information rich but knowledge poor. There is a lack of effective analysis tools to discover the hidden relationships and trends in medical data obtained from clinical records. This study reviews the state of the art research on heart disease diagnosis and prediction. Keywords: Data mining;heart disease;prediction;web;diagnosis
