Acute myocardial infarction (AMI) is the leading cause of death worldwide, with early diagnosis still being difficult. Promising new cardiac biomarkers such as troponins and creatine kinase (CK) isoforms are being studied and integrated into clinical practice for early diagnosis of AMI. ⋯ The introduction of novel high-sensitivity troponin assays has enabled more sensitive and timely diagnosis or exclusion of acute coronary syndromes. This review summarizes the available information on the potential of troponins and other cardiac markers in early diagnosis and prognosis of AMI, and provides perspectives on future diagnostic approaches to AMI.

The reported association of the leptin receptor (LEPR) protein with hepatocellular carcinoma (HCC) carcinogenesis prompted us to evaluate whether genetic polymorphisms of the LEPR gene affect susceptibility to HCC and its clinicopathologic characteristics. ⋯ The Lys109Arg and Gln223Arg polymorphisms of the LEPR gene are associated with susceptibility to HCC but not with its clinicopathologic features. These polymorphisms may represent genetic markers for the risk of HCC in the context of chronic HBV infection.
