^aCHD history was identified in the medical record documentation, if at least one of the following conditions occurred in medical records 3 years prior to the baseline survey: angina, MI, other coronary heart disease or coronary artery disease, coronary angioplasty or bypass.
^bData were obtained from 4602 patients without a CHD history and 2029 patients with a CHD history.
^cUKPDS CHD event is defined as fatal or non-fatal MI.
^dFramingham CHD event is defined as angina pectoris, MI, coronary insufficiency, sudden or non-sudden CHD death.
