Abstract:
Atrial fibrillation (AF) is a highly prevalent arrhythmia with pronounced morbidity and mortality. Genetics analysis has established electrophysiological substrates, which determine individual vulnerability to AF occurrence and maintenance. MicroRNAs (miRNAs) found in virtually all organisms function as negative regulators of protein-coding genes. Several studies have suggested a role for miRNAs in the regulation of cardiac excitability and arrhythmogenesis. This review is based on 18 studies conducted between 2009 and 2013 to investigate the association of miRNAs with AF. miRNAs are discussed here as candidate biomarkers for AF in blood and cardiac tissues and as potential targets for AF therapy.

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
