* Meet HF criteria but have an alternative explanation for findings.

^† Do not meet full criteria for definite HF.

^‡ p-value for whether either pre-HF category as a whole predicts time to the outcome.

^§ Event proportions are based on overall sample.

^|| Model adjusted for age, sex, SBP, antihypertensive medications, current smoking, prevalent CHD, and body mass index.

HF = heart failure; CHD = coronary heart disease; CVD = cardiovascular disease.
