  • HRs for continuous variables indicate hazard change per single integer measurement unit.

  • Statistically significant differences are designated in bold.

  • *p<0.05; **p<0.01; ***p<0.001 by multivariate survival analysis.

  • ACEI, ACE inhibitor; ARB, angiotensin receptor blocker; BP, blood pressure; CAD, coronary artery disease; CHF, congestive heart failure; CABG, coronary artery bypass grafting; COPD, chronic obstructive pulmonary disease; CV, cardiovascular; MI, myocardial infarction; PAD, peripheral arterial disease.
