This retrospective, single-center cohort study included patients who underwent successful timely primary percutaneous coronary intervention (PCI) for first-onset AMI between September 2017 and March 2018. The PCSK9 inhibitor group comprised patients who received 75 mg alirocumab up to 7 days after AMI, while the standard therapy group comprised patients who did not. We evaluated the change in TNF-α levels and the L-arginine/ADMA ratio at the time of hospital admission and prior to discharge. PCSK9 inhibitor therapy in the early phase after AMI suppressed TNF-α levels (standard therapy group, 1.64 ± 2.14 pg/mL vs. PCSK9 inhibitor group, 0.26 ± 0.33 pg/mL; p = 0.033) and increased the L-arginine/ADMA ratio (standard therapy group, - 13.0 ± 39.7 vs. PCSK9 inhibitor group, 23.2 ± 39.7; p = 0.042). Upon multiple regression analysis adjusted for sex, age, and peak creatine kinase levels, PCSK9 inhibitor therapy was associated with TNF-α suppression (p = 0.025; β = - 0.235, 95% confidence interval [CI], - 0.436 to - 0.033). The L-arginine/ADMA ratio was also analyzed using multiple regression, adjusted for sex, age, peak creatine kinase levels, and smoking, showing a significant improvement in the ratio (p = 0.018; β = 41.913, 95% CI, 10.337-73.491). Moreover, a weak negative correlation was suggested between the change in TNF-α levels and the change in L-arginine/ADMA ratio (r = - 0.393, p = 0.058).

Although elevated estimated right ventricular systolic pressure (eRVSP) indicating pulmonary hypertension is the best proposed additional predictor, we hypothesized that transthoracic echocardiography (TTE) parameters more directly reflecting left atrial pressure (LAP) would more accurately predict LVD than eRVSP. Furthermore, predictors of a significant decline in LVEF remain unknown. We retrospectively studied 622 patients, aged 20-87 years, who underwent MVr for severe chronic primary MR. As previously reported predictors of postoperative LVD, we collected seven preoperative TTE parameters, including LVESD, LVEF, eRVSP, LV end-diastolic dimension, left atrial volume index (LAVI), early transmitral annular (e') velocity, and atrial fibrillation. Furthermore, as LAP-related TTE parameters, we collected left atrial dimension, E-wave velocity, and E/e' ratio, in addition to eRVSP and LAVI. Using multivariate logistic regression and receiver operating characteristic curve analyses, we explored predictors of early postoperative LVD, defined as LVEF < 50% measured on postoperative day 7. We further explored predictors of a significant decline in LVEF, defined as an absolute decline in LVEF of > 12 percentage points, the third quintile of the data. Incidences of postoperative LVD and a significant LVEF decline were 12.9% and 23.2%, respectively. In addition to LVESD and LVEF, E-wave velocity, but not eRVSP, remained a significant predictor of postoperative LVD. E-wave velocity, LVESD, and LVEF had additive effects in risk prediction. Furthermore, E-wave velocity was the strongest predictor of a significant LVEF decline. E-wave velocities > 121.5 cm/s and > 101.5 cm/s were associated with increased risks of postoperative LVD (odds ratio [OR], 2.896; 95% confidence interval [95%CI], 1.792-4.681; p < 0.001) and a significant LVEF decline (OR, 6.345; 95%CI, 3.707-10.86; p < 0.001), respectively.
