The relation between the incidence and severity of acute kidney injury (AKI) and clinical outcomes remains unclear in patients with DeBakey type III acute aortic dissection (AAD). We retrospectively assessed 56 patients admitted to our hospital for type III AAD within 48 hours of the onset of symptoms. The presence of AKI was identified, and its severity was staged on the basis of changes in serum creatinine (SCr) levels within 7 days after admission. ⋯ These associations were more pronounced in patients with relatively severe AKI. Multivariate analysis revealed that SCr level on admission and DeBakey type IIIb with renal artery involvement were major predictors of AKI. In conclusion, renal function on admission and renal artery involvement were significant risk factors for AKI, which was associated with poor outcomes and enhanced inflammatory response during hospitalization in patients with type III AAD.

Percutaneous coronary intervention in the setting of acute myocardial infarction is known to predict stent thrombosis (ST). This study aims to compare the ST rates across different coronary subsets. This was an observational cohort study from a large, single-center registry. ⋯ Clopidogrel cessation was the strongest predictor of ST (definite ST, HR 17.00, 95% CI 7.54 to 38.31; definite/probable ST, HR 4.69, 95% CI 2.39 to 9.20). In conclusion, in patients who underwent percutaneous coronary intervention, the acuity of clinical presentation corresponds to an increase in ST incidence. Adherence to clopidogrel is critical to prevent ST in patients who underwent percutaneous coronary intervention, especially in STEMI.
