Key result
Hypertension was associated with higher annual event rates than normotension in patients with known CAD (7.0% vs 5.7%, P=0.02), suspected CAD, and those with normal stress echocardiograms.

May warrant heightened surveillance in hypertensive CAD patients despite normal stress echo; leaves open whether intensified BP control modifies risk.
Cohort (n=11,542)
Absolute Event Rate: 7% vs 5.7%
p-value: p=0.02
Stress echocardiography provides effective prognostic stratification in both hypertensive and normotensive patients, though a normal test predicts better survival in normotensive individuals.
Cortigiani et al. (2011) conducted a cohort in Known or suspected coronary artery disease (n=11,542). Hypertension vs. Normotension was evaluated on Death or non-fatal infarction (p=0.02). Hypertension was associated with higher annual event rates than normotension in patients with known CAD (7.0% vs 5.7%, P=0.02), suspected CAD, and those with normal stress echocardiograms.
