A comparison of risk scores' long-term predictive abilities for patients diagnosed with ST elevation myocardial infarction who underwent early percutaneous coronary intervention.

Objective. To compare the long-term (5 year) prognostic values of commonly used risk scores on major adverse cardiovascular events (MACE) in a cohort of patients who underwent primary PCI for STEMI. Design. We created a composite endpoint of MACE, defined as the occurrence of any of the following events within 5 years: ischemic or hemorrhagic stroke, target vessel revascularization, nonfatal myocardial infarction, cardiovascular death. We dichotomized risk scores into high risk and not high risk according to the literature's pre-existing cutoffs as follows: GRACE score >127 = high risk, SYNTAX I score ≥33 = high risk, SYNTAX II ≥32 high risk, TIMI >8 = high risk. We utilized the area under the receiver operating characteristic curve (AUC) as the metric for predictive ability. Results. There were 768 patients in this study and 416 (54.2%), 209 (27.2%), 511 (66.5%), and 74 (9.6%) were at high risk according to the GRACE, SYNTAX I, SYNTAX II, and TIMI scores, respectively. The AUCs for 5-year MACE were 0.54 (95% confidence interval (CI): 0.49-0.59, p = .0947), 0.79 (95% CI: 0.75-0.83, p < .0001), 0.58 (95% CI: 0.54-0.62, p = .0004), and 0.5 (95% CI: 0.48-0.53, p = .7259), respectively. Conclusion. SYNTAX I score was superior in predicting MACE in patients with STEMI and a high burden of CAD. Utilizing the basal SYNTAX I score in STEMI patients with significant non-culprit CAD may improve risk stratification, decision-making, and outcomes.

Relationship between Echocardiographic and Magnetic Resonance-Derived Measurements of the Thoracic Aorta in Turner Syndrome Patients.

INTRODUCTION: Turner syndrome (TS) is assigned to the rare diseases group. Morbidity and mortality of TS patients are high, particularly due to the cardiovascular disorders, so monitoring for cardiovascular complications must be ensured. The data demonstrate a strong correlation between 2-dimensional echocardiographic (2Decho) evaluation and magnetic resonance imaging (MRI); still, according to recent guidelines, MRI remains a gold standard. In this study, we aimed to compare aortic dimensions on MRI and 2Decho in TS patients. METHODS: 50 TS patients (≥18 years) were enrolled into the cross-sectional study. 2Decho and MRI were performed. The measurements of the aorta were assessed in five standard positions on 2Decho and in 9 standard positions on MRI; ASI (aortic size index) of the ascending aorta was calculated since reduced adult height is observed in TS patients. RESULTS: ASI on echocardiography strongly correlated with ASI on MRI in all positions of the ascending aorta, but significantly larger medians of ASI were found on 2Decho in all positions of the ascending aorta and arch when compared with MRI measurements. Still, the prevalence of aortic sinus dilation was significantly and more frequently (52% vs. 38%, p < 0.001) observed on MRI when compared with 2Decho. CONCLUSION: The relation of aortic size was significant in all positions when comparing the MRI and 2Decho methods; still, the dilatation of the sinus of aorta was more frequently found on MRI compared with echocardiography.
