The relationship between pulse pressure and prognosis in patients with chronic coronary syndrome (CCS) is contradictory. In the present study, we aimed to examine the relationship between intra-aortic pulse pressure (IAPP) and major adverse cardiovascular events (MACE) in patients with CCS undergoing percutaneous coronary intervention (PCI). A total of 139 CCS patients who underwent elective PCI with regular one-year follow-up, were stratified into two subgroups according to IAPP. The primary outcomes included the occurrence of MACE, defined as cardiovascular death, acute myocardial infarction with ST-segment elevation (STEMI), acute myocardial infarction without ST-segment elevation (NSTEMI), target vessel revascularization (TVR), and stroke. The mean age of the patients was 57.6 ± 10.4 years, 32% of whom were female. The mean IAPP, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were 54.0 ± 17.6 mmHg, 129.7 ± 20 mmHg, and 75.8 ± 11.8 mmHg, respectively. SBP, IAPP, and left ventricular ejection fraction (LVEF) were significantly higher in the high IAPP group (p &lt; .001, p &lt; .001, p = .001, respectively). The MACE rate was significantly higher in the low IAPP group than in the high IAPP group (30.4% vs. 8.6%, p = 0,001). The LVEF (OR = 0.93, CI:0.88–0.99, p = .025) and IAPP (OR = 0.89, CI:0.83–0.95, p = .001) were found to be independent predictors of MACE. The IAPP value of 39.5 mmHg was identified as an effective cutoff point for prediction of MACE-free survival rates (AUC:0.853, CI:0.768–0.937). Invasively measured IAPP has prognostic information about cardiovascular outcomes in patients with CCS. The risk of MACE is significantly greater in CCS patients with low IAPP compared with those who have high IAPP values.
