Prognostic value and clinical predictors of intramyocardial hemorrhage measured by CMR T2* sequences in STEMI.

Recent studies show that microvascular injury consists of microvascular obstruction (MVO) and intramyocardial hemorrhage (IMH). In patients with reperfused ST-segment elevation myocardial infarction (STEMI) quantitative assessment of IMH with T2* cardiovascular magnetic resonance imaging (CMR) appears to be useful in evaluation of microvascular damage. The current study aimed to investigate feasibility of this approach and to correlate IMH with clinical and CMR parameters.

Circulating Sphingosine-1-Phosphate as A Non-Invasive Biomarker of Heart Transplant Rejection.

Accumulating evidence has confirmed that the expression of sarcoplasmic reticulum calcium ATPase 2a (SERCA2a) is downregulated in heart failure and cardiac allograft rejection. Although many SERCA2a-related genes and proteins involved in the regulation of myocardial Ca fluxes have been explored, its related metabolites remain poorly studied. Our main objective was to identify circulating SERCA2a-related metabolites altered in cardiac allograft rejection and to determine whether these could serve as non-invasive biomarkers.

Antithrombotic treatment during coronary angioplasty after failed thrombolysis: strategies and prognostic implications. Results of the RESPIRE registry.

Background: Thrombolysis is still used when primary angioplasty is delayed for a long time, but 25%-30% of patients require rescue angioplasty (RA). There are no established recommendations for antithrombotic management in RA. This registry analyzes regimens for antithrombotic management.

SERCA2a: A potential non-invasive biomarker of cardiac allograft rejection.

Background: The detection of heart transplant rejection by non-invasive methods remains a major challenge. Despite the well-known importance of the study of sarcoplasmic reticulum Ca-ATPase (SERCA2a) in the heart, its role as a rejection marker has never been analyzed. Our objective in this study was to determine whether circulating SERCA2a could be a good marker of cardiac rejection.

Influence of metabolic syndrome on development of cardiac allograft vasculopathy in the transplanted heart.

Background: Cardiac allograft vasculopathy (CAV) is the main cause of graft failure and death 1 year after heart transplantation (HTx). Metabolic syndrome (MS) increases the risk of cardiovascular events by endothelial dysfunction. The purpose of this study was to determine if patients with MS developed a higher risk of CAV 1 year after HTx.
