Abstract
Objectives: Circulating microRNAs (miRNAs) are promising as biomarkers for various diseases. We examined the release patterns of cardiospecific miRNAs in a closed-chest, large animal ischemia-reperfusion model and in patients with ST elevation myocardial infarction (STEMI). Methods: Six anesthetized pigs were subjected to coronary occlusion-reperfusion. Plasma, urine, and clinical parameters were collected from 25 STEMI patients undergoing primary percutaneous coronary intervention. miRNA was extracted and measured with qPCR. Results: In the pig reperfusion model miR-1, miR-133a, and miR-208b increased rapidly in plasma with a peak at 120 min, while miR-499-5p remained elevated longer. In patients with STEMI all 4 miRNAs increased abruptly... (More)
Objectives: Circulating microRNAs (miRNAs) are promising as biomarkers for various diseases. We examined the release patterns of cardiospecific miRNAs in a closed-chest, large animal ischemia-reperfusion model and in patients with ST elevation myocardial infarction (STEMI). Methods: Six anesthetized pigs were subjected to coronary occlusion-reperfusion. Plasma, urine, and clinical parameters were collected from 25 STEMI patients undergoing primary percutaneous coronary intervention. miRNA was extracted and measured with qPCR. Results: In the pig reperfusion model miR-1, miR-133a, and miR-208b increased rapidly in plasma with a peak at 120 min, while miR-499-5p remained elevated longer. In patients with STEMI all 4 miRNAs increased abruptly from 70-fold to 3,000-fold in plasma, with a peak within 12 h (p < 0.01). miR-1 and miR-133a both correlated strongly with the glomerular filtration rate (GFR), indicating renal elimination. This was confirmed by detection of miR-1 and miR-133a, but not miR-208b or miR-499-5p, in urine. Peak values of miR-208b correlated with peak troponin and the ejection fraction. Conclusion: We demonstrate a distinct and rapid increase in levels of cardiospecific miRNA in the circulation after myocardial infarction. Release of miRNAs correlated with cardiomyocyte necrosis markers, the ejection fraction, and the GFR, indicating a possible role for these molecules as biomarkers for the diagnosis of STEMI as well as the prediction of long-term complications.
