Ascending aorta dilatation is associated to hard cardiovascular events, follow-up from multicentric ARGO-Perspective project.

Aortic root dilatation has been proposed as hypertension-mediated organ damage (HMOD). Nevertheless, the role of the aortic root dilatation as a possible additional HMOD is still unclear since studies conducted so far are quite heterogeneous regarding the type of population analyzed, the aortic tract considered, and the type of outcomes accounted for. The aim of the present study is to assess whether the presence of aortic dilatation is associated with strong cardiovascular (CV) events (MACE: heart failure, CV death, stroke, acute coronary syndrome, myocardial revascularization) in a population of patients affected by essential hypertension. Four hundred forty-five hypertensive patients from six Italian hospitals were recruited as part of ARGO-SIIA study1. For all centers, follow-up was obtained by re-contacting all patients by telephone and through the hospital's computer system. Aortic dilatation (AAD) was defined through absolute sex-specific thresholds as in previous studies (41 mm for males, 36 mm for females). Median follow-up was 60 months. AAD was found to be associated with the occurrence of MACE (HR = 4.07 [1.81-9.17], p < 0.001). This result was confirmed after correction for main demographic characteristics such as age, sex and BSA (HR = 2.91 [1.18-7.17], p = 0.020). At penalized Cox regression, age, left atrial dilatation, left ventricular hypertrophy and AAD were identified as best predictor of MACEs and AAD resulted a significant predictor of MACEs even after correction for these confounders (HR = 2.43 [1.02-5.78], p = 0.045). The presence of AAD was found to be associated with an increased risk of MACE independently of for major confounders, including established HMODs.

Serum uric acid to creatinine ratio and risk of preeclampsia and adverse pregnancy outcomes.

OBJECTIVE: Preeclampsia is one of the most severe diseases among the hypertensive disorders of pregnancy (HDP) and the leading cause of maternal and fetal morbidity and mortality. It is of crucial importance to early identify women at a high risk for preeclampsia to implement appropriate preventive strategies. In our study, we aimed to test the hypothesis that serum uric acid to creatinine ratio (SUA/sCr) is related to the development of preeclampsia and maternal and neonatal complications. METHODS: We searched for uric acid and creatine values in the medical records of 269 women who consecutively attended our HDP Clinic from December 2018 to December 2022. We compared the baseline characteristics of participants with normotensive pregnancy ( n  = 57), to those with HDP without preeclampsia (HDP-non-PE) ( n  = 100) and those with preeclampsia ( n  = 112), and we performed adjusted logistic regression analysis to test the associations between SUA/sCr and the development of preeclampsia and maternal and neonatal complications. RESULTS: SUA/sCr was consistently higher in women with preeclampsia in all trimesters of pregnancy. Higher SUA/sCr at the third trimester was associated with an increased odd of developing preeclampsia [odds ratio (OR) 1.29, confidence interval (CI) 1.15-1.50, P  = 0.001], preterm birth (OR 1.23, CI 1.05-1.45, P  = 0.011), and composite neonatal outcome (OR 1.33, CI 1.12-1.59, P  = 0.001), after adjustment for age, BMI before pregnancy, nulliparity, antihypertensive therapy, and acetylsalicylic acid therapy during pregnancy. CONCLUSIONS: Having higher SUA/sCr during pregnancy is associated with the development of PE and adverse pregnancy outcomes. Controlled prospective studies are warranted to clarify the predictive power of this novel marker during pregnancy.
