Abstract:
Current guidelines recommend aggressive management of hypertension. Recent evidence suggested potential harm with low blood pressure targets in patients with peripheral artery disease. We investigated the association of a history of hypertension and office systolic blood pressure (SBP) with major adverse cardiovascular events (MACEs) and major adverse limb events (MALEs). Methods and Results: The EUCLID trial (Examining the Use of Ticagrelor in Peripheral Artery Disease) included 13 885 participants with symptomatic peripheral artery disease; median follow-up was 30 months. Cox proportional hazards regression was used to calculate hazard ratios (HRs) for any MACE, MALE, and MALE including lower extremity revascularization. A clinical history of arterial hypertension was present in 10 857 (78%) participants, and these participants were older and more likely to be female when compared with the 3026 (22%) patients without hypertension. In patients with a history of hypertension, the adjusted hazard ratio for MACE was 0.94, 95% CI, 0.82–1.08; P =0.39, and the adjusted hazard ratio for MALE was 1.08, 95% CI, 0.96–1.23; P =0.21. During follow-up, average SBP was 135 mm Hg (125–145). Every 10 mmHg increase in SBP 〉 125 mmHg was associated with an increased risk of MACE (HR, 1.10 [95% CI, 1.06–1.14]; P 〈 0.001), a marginally increased risk of MALE (HR, 1.07 [95% CI, 1.00–1.15]; P =0.062), and an increased risk of MALE/lower extremity revascularization (HR, 1.08 [95% CI, 1.04–1.11]; P 〈 0.001). Every decrease in 10 mmHg SBP ≤125 mmHg was associated with an increased risk of MACE (HR, 1.19 [95% CI, 1.09–1.31]; P 〈 0.001) but not MALE or MALE/lower extremity revascularization (HR, 1.02 [95% CI, 0.84–1.23], P =0.824; HR, 1.04 [95% CI, 0.95–1.13], P =0.392, respectively). Conclusions: History of hypertension was not associated with higher hazard for MACE or MALE in patients with peripheral artery disease. In contrast, there was a higher hazard of MACE in patients with out-of-target low and high SBP. High but not low SBP was associated with an increased risk of ischemic limb events.
