Abstract
BACKGROUND Cardiac transplant is an effective long-term management option for several severe cardiac diseases. These cardiac transplant patients may present to the emergency department with a range of issues involving the cardiac transplantation, including complications due to their transplant as well as altered presentations of disease resulting from their transplant. OBJECTIVE This narrative review provides a focused guide to the evaluation and management of patients with cardiac transplantation and its complications. DISCUSSION Cardiac transplant is an effective therapy for end-stage heart failure. A transplanted heart varies both anatomically and physiologically from a native heart. Several significant complications may occur. Graft failure, rejection, and infection are common causes of morbidity and mortality within the first year of transplant. As these patients are on significant immunosuppressive medication regimens, they are at risk of infection, but inadequate immunosuppression increases the risk of acute rejection. A variety of dysrhythmias such as atrial fibrillation and ventricular dysrhythmias may occur. These patients are also at risk of acute coronary syndrome, cardiac allograft vasculopathy, and medication adverse events. Importantly, patients with acute coronary syndrome can have an altered presentation with the so-called "painless" myocardial infarction. Consultation with the transplant physician is recommended, if available, for these patients to assist in evaluation and management. CONCLUSIONS An understanding of the presentations and various complications that may affect patients with cardiac transplant will assist emergency clinicians in the care of these patients.

Diagnostic performance of cardiac magnetic resonance for the detection of acute cardiac allograft rejection: a systematic review and meta-analysis. J Thorac Dis 2015; 7:252-63.

Abstract
BACKGROUND Several studies have addressed the diagnostic accuracy of cardiac magnetic resonance (CMR) to assess acute cardiac allograft rejection (ACAR) compared with endomyocardial biopsy (EMB). But the methodological heterogeneity limited the clinical application of CMR. Accordingly, we have sought a comprehensive, systematic literature review and meta-analysis for the purpose. METHODS Studies prior to September 1, 2014 identified by Medline/PubMed, EMBASE and Cochrance search and citation tracking were examined by two independent reviewers. A study was included if a CMR was used as a diagnostic test for the detection of ACAR. RESULTS Of the seven articles met the inclusion criteria. Only four studies using T2 relaxation time as a CMR parameter could be pooled results, because the number of studies using other parameters was less than three. By using DerSimonian-Laird random effects model, meta-analysis demonstrated a pooled sensitivity of 90% [95% confidence interval (CI), 79% to 97%], a pooled specificity of 83% (95% CI, 78% to 88%), and a pooled diagnostic odds ratio (DOR) of 61.66 (95% CI, 18.09 to 210.10). CONCLUSIONS CMR seems to have a high sensitivity and moderate specificity in the diagnosis of ACAR. However, as a result of CMR for diagnostic ACAR should be comprehensively considered by physicians and imaging experts in the context of clinical presentations and imaging feature. Further investigations are still required to test different parameters and study condition.

Abstract
Myocardial infarction (MI) is a serious heart disease. The cardiac cells of patients with MI will die due to lack of blood for a long time. In this study, we aimed to find new targets for MI diagnosis and therapy. We downloaded GSE22229 including 12 blood samples from healthy persons and GSE29111 from Gene Expression Omnibus including 36 blood samples from MI patients. Then we identified differentially expressed genes (DEGs) in patients with MI compared to normal controls with p value < 0.05 and |logFC| > 1. Furthermore, interaction network and sub-network of these of these DEGs were constructed by NetBox. Linker genes were screened in the Global Network database. The degree of linker genes were calculated by igraph package in R language. Gene ontology and kyoto encyclopedia of genes and genomes pathway analysis were performed for DEGs and network modules. A total of 246 DEGs were identified in MI, which were enriched in the immune response. In the interaction network, LCK, CD247, CD3D, FYN, HLA-DRA, IL2, CD8A CD3E, CD4, CD3G had high degree, among which CD3E, CD4, CD3G were DEGs while others were linker genes screened from Global Network database. Genes in the sub-network were also enriched in the immune response pathway. The genes with high degree may be biomarkers for MI diagnosis and therapy.
