* Meet HF criteria but have an alternative explanation for findings.
† Do not meet full criteria for definite HF.
‡ Includes recognized myocardial infarction, coronary insufficiency and angina pectoris.
§Includes chronic obstructive pulmonary disease, chronic bronchitis, emphysema and asthma.
HF = heart failure; HDL = high density lipoprotein; GFR = glomerular filtration rate; CHD = coronary heart disease.
