Left ventricular end-diastolic pressure (LVEDP) is an important hemodynamic marker of left ventricular performance and affects coronary perfusion. We evaluated the association of LVEDP with patient outcomes after elective or urgent percutaneous coronary intervention (PCI). We included n = 49,600 patients undergoing elective or urgent PCI. Patients were divided according to LVEDP tertile for descriptive analysis. The primary end point was in-hospital mortality. A recursive partitioning tree model for mortality was built to guide decision-making in patients with high LVEDP undergoing nonemergent PCI. Overall, n = 18,099 patients had an LVEDP <13 mm Hg, n = 15,416 had an LVEDP 13 to 18 mm Hg, and n = 16,085 had an LVEDP >18 mm Hg. Patients in the high LVEDP tertile had a worse clinical and angiographic/procedural profile and experienced a higher incidence of in-hospital post-PCI adverse outcomes, including death (LVEDP <13 mm Hg 0.3% vs LVEDP 13 to 18 mm Hg 0.4% vs LVEDP >18 mm Hg 0.8%, p <0.001). An elevated LVEDP was an independent predictor of adverse outcomes including mortality. An LVEDP ≥26 mm Hg was identified as a marker of high mortality (1.5%) in patients who underwent elective PCI, with rates varying from 0.5% to 10.4%, based upon a clinical profile defined by hemoglobin, systolic blood pressure, renal and left ventricular function, and atrial fibrillation. In conclusion, an elevated LVEDP is observed in 1/3 of the patients who underwent elective or urgent PCI and is associated with higher rates of in-hospital adverse outcomes, including death. Patients with an LVEDP ≥26 mm Hg who underwent elective PCI had markedly higher mortality rates, suggesting that such patients may warrant further optimization before PCI.
