BACKGROUND: Diagnosis and percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) are time-sensitive. Triage and algorithms identify patients at high-risk. However, additional prediction tools are warranted for prioritized care based on predicted coronary pathologies and PCI complexity. Pulse-wave velocity (PWV) is a non-invasive measurement related to cardiovascular morbidity, and their exact value in ACS evaluation is unclear.
METHODS: In patients undergoing coronary angiography (CA) and - if warranted - PCI for ACS evaluation at a tertiary university hospital in Vienna, Austria, brachial-ankle (ba)PWV and carotidfemoral (cf)PWV were prospectively measured from 01/2020-01/2021.
RESULTS: PWV was measured in 58 patients (60.3% male; 65 [61-69] years). Risk prediction scores (GRACE, CRUSADE, TIMI), cardiac enzymes, and fraction of patients with a three-vessel disease were significantly higher in the pathological PWV ranges. Adjusted for age and co-morbidities, baPWV independently predicted the LAD being relevantly stenotic (crude OR=1.416 [1.143-1.755], p=0.001; adjusted OR=1.340 [1.039-1.727;], p=0.024; cut-off 15.5 m/s in CART-analysis), being the culprit lesion (crude OR=1.320 [1.094-1.594], p=0.004; adjusted OR=1.311 [1.037-1.657], p=0.024; cut-off 15.5 m/s), and being totally occluded (crude OR=1.422 [1.113-1.818], p=0.005; adjusted OR=1.677 [1.189-2.366], p=0.003; cut-off 19.6 m/s). Moreover, CA or PCI complexity were associated with higher PWV.
CONCLUSIONS: Pathological PWV as a surrogate for arterial stiffness, polyvascular disease and a larger atherosclerotic burden was associated with GRACE, CRUSADE, and TIMI scores, and PCI duration and complexity. BaPWV independently predicted relevant LAD pathologies, and is suggested as a potential novel triage and prioritization tool for suspected NSTE-ACS in emergency departments.
