Cognitive impairment and frailty are highly prevalent in older adults undergoing transcatheter aortic valve replacement. This study aimed to investigate the relationship of cognitive impairment and frailty with functional recovery after transcatheter aortic valve replacement. ⋯ Preoperative cognitive function plays a vital role in functional recovery after transcatheter aortic valve replacement, regardless of baseline frailty status. Impaired cognition may increase functional decline in the absence of frailty, whereas intact cognition may mitigate the detrimental effects of frailty. Cognitive assessment should be routinely performed prior to transcatheter aortic valve replacement.

Despite differing underlying pathophysiology, type 1 and type 2 myocardial infarction share many of the same diagnostic criteria and can be challenging to differentiate in clinical practice. Correctly differentiating type 1 from type 2 myocardial infarction is important because they are managed differently. The aim of this study was to compare the patterns of rise of cardiac troponin (cTn) and creatine kinase MB (CK-MB) in type 1 and type 2 myocardial infarction. ⋯ Both cTnT and CK-MB rise higher in type 1 than in type 2 myocardial infarction. Meanwhile, cTnT tends to rise out of proportion to CK-MB in type 2 myocardial infarction. These patterns may have considerable implications for the differentiation and subsequent treatment of patients with type 1 versus type 2 myocardial infarction.
