Here, we report a rare case of isolated leukemic infiltrate of the myocardium (extramedullary involvement) presenting as restrictive cardiomyopathy in a patient in complete remission of acute myeloid leukemia. It was evaluated with multimodality imaging studies (echocardiography and cardiac MRI) and further confirmed by pathology. The present case highlights the importance of maintaining a high degree of clinical suspicion when evaluating patients with progressive ventricular hypertrophy of unknown cause, including recognition of the potential involvement by recurrent hematologic malignancy...

Spontaneous coronary artery vasospasm is one of the important causes of acute chest pain syndromes. The diagnosis of diffuse multifocal spasm can be quite challenging and it could be easily mistaken for diffuse coronary artery disease. The use of intracoronary nitroglycerin can relieve spasm and reveal the real extent of coronary artery disease. Herein we present a case presenting with acute myocardial infarction due to severe coronary artery spasm that had even received fibrinolytic therapy. Multiple narrowing was shown during coronary angiography and the patient was scheduled for percutaneous coronary intervention (PCI)...

We used a porcine model of acute myocardial infarction to study the signal evolution of ischemic myocardium on diffusion-weighted magnetic resonance images (DWI). Eight Chinese miniature pigs underwent percutaneous left anterior descending or left circumflex coronary artery occlusion for 90 minutes followed by reperfusion, which induced acute myocardial infarction. We used DWI preprocedurally and hourly for 4 hours postprocedurally. We acquired turbo inversion recovery magnitude T2-weighted images (TIRM T2WI) and late gadolinium enhancement images from the DWI slices...

Patients with asymptomatic heart failure (HF; stage A and B) are characterized by maladaptive left ventricular (LV) remodeling. Classic 4-group classification of remodeling considers only LV mass index and relative wall thickness as variables. Complex remodeling classification (CRC) includes also LV end-diastolic volume index. Main aim was to assess the prognostic impact of CRC in stage A and B HF. A total of 1,750 asymptomatic subjects underwent echocardiographic examination as a screening evaluation in the presence of cardiovascular risk factors...

BACKGROUND: Non-thyroidal illness syndrome (NTIS) is characterized by decreased serum triiodothyronine level without increased thyroid-stimulating hormone level during critical illness. The summary data on the prevalence of NTIS in cardiovascular patients are lacking, and its prognostic role in cardiovascular patients is also unclear. METHODS: We performed a systematic review and meta-analysis to comprehensively determine the prevalence and the prognostic role of NTIS in cardiovascular patients...

Importance: In 2011, the US Centers for Medicare & Medicaid Services (CMS) changed its reimbursement policy for hemodialysis to a bundled comprehensive payment system that included the cost of erythrocyte-stimulating agents (ESAs). Also in 2011, the US Food and Drug Administration revised the drug label for ESAs, recommending more conservative dosing in patients with chronic kidney disease. In response to concerns that these measures could have adverse effects on patient care and outcomes, the CMS and the FDA initiated a collaboration to assess the effect...

Presently described is the rare complication of sickle cell trait (HbAS) with acute inferior myocardial infarction in a young adult patient. Angiogram revealed microemboli in the distal thin segment of the circumflex (Cx) artery. Anticoagulant and anti-aggregant therapies were initiated to restore Cx artery flow. HbAS was detected as an underlying pathology. ST segments returned to the isoelectric line and the patient became asymptomatic.

Right coronary artery (RCA) occlusion in inferior acute myocardial infarction is usually heralded by ST-elevation both in inferior and in right precordial leads. We report the case of a 68-year-old male, who presented marked ST-elevation in inferior leads, mirrored by ST-depression in anterior-septal and lateral leads. Right precordial lead electrocardiogram unexpectedly showed ST-depression V1R-V5R leads. Coronary angiography showed mid-left anterior descending (LAD) coronary near-complete occlusion with distal wrapping LAD...

AIMS: Peripartum cardiomyopathy (PPCM) is a major cause of acute heart failure in the peripartum period and considered potentially life threatening. While many aspects of its clinical profiles have been frequently reported, functional analysis, in particular of the right ventricle, and tissue characterization by cardiovascular magnetic resonance (CMR) imaging have been only sporadically described. The aim of the present study was to analyse pathological alterations and their prognostic relevance found in CMR imaging of patients newly diagnosed with PPCM...

OBJECTIVE: The reprogramming of cardiac fibroblasts into induced cardiomyocyte-like cells improves ventricular function in myocardial infarction models. Only integrating persistent expression vectors have thus far been used to induce reprogramming, potentially limiting its clinical applicability. We therefore tested the reprogramming potential of nonintegrating, acute expression adenoviral (Ad) vectors. METHODS: Ad or lentivirus vectors encoding Gata4 (G), Mef2c (M), and Tbx5 (T) were validated in vitro...
