Abstract Background Cardiac amyloidosis, a progressive cardiac disease, results from the accumulation of undegraded proteinaceous substrates in the extracellular matrix of the heart. It may present as acute coronary syndrome (ACS); therefore, a clear distinction remains challenging in clinical practice. We describe a case of cardiac amyloidosis mimicking ACS. Case summary A 72-year-old man experienced chest discomfort for 2 days. He gradually developed dyspnoea during the preceding month. Electrocardiogram (ECG) showed sinus rhythm with right bundle branch block and low voltage. Echocardiography revealed concentric left ventricular thickening, biatrial dilation, and preserved ejection fraction with predominantly left ventricular basal hypokinesis. Serial testing of the cardiac biomarkers showed persistently increased high-sensitive cardiac troponin T levels and normal serum creatine kinase myocardial band levels. He was diagnosed with ACS with haemodynamic stability. However, coronary angiography demonstrated non-obstructive coronary arteries. Furthermore, significant macroglossia and periorbital purpura were noticed. Laboratory investigations revealed elevated serum immunoglobulin free light chain (FLC) kappa and lambda levels with an increased FLC ratio. Histological analysis of the biopsied abdominal skin confirmed amyloidosis. Discussion Cardiac amyloidosis often presents as restrictive cardiomyopathy. The usual symptoms include dyspnoea and peripheral oedema. Chest pain may manifest rarely, leading to misdiagnosis as coronary artery disease. Some findings suggestive of cardiac amyloidosis include clinical signs such as amyloid deposits, dyspnoea, low ECG voltage, and basal-predominant hypokinesis with relative apical sparing in echocardiography. Serum FLC test and abdominal skin biopsy can confirm the diagnosis of amyloidosis when a myocardial biopsy is not feasible.

Long Term Follow Up

Aim To study a relationship of several factors (clinical and genetical markers) with unfavorable outcomes in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in long-term follow-up.Material and methods This full-design, prospective study included 415 patients with NSTE-ACS. 266 patients were evaluated for the presence of multifocal atherosclerosis (MFA). Typing of polymorphic variants rs1041981 LTA, rs1800629 TNF, rs4986790, and rs498679 TLR4, and also rs3024491 and rs1800872 IL10 was performed. Follow-up period lasted for 67±4 months. By the end of this period, information about clinical outcomes for 396 patients became available.Results During the entire follow-up period, unfavorable outcomes were observed in 239 (57.5 %) patients with NSTE-ACS. The following clinical signs were associated with unfavorable outcomes: history of myocardial infarction, age >56 years, left ventricular ejection fraction (LV EF) ≤50 % and GRACE score ≥100, significant stenosis of brachiocephalic arteries, MFA, carriage of genotype А / А rs1041981 LTA (OR, 6.1; р=0.02) and allele А (OR, 1.9; р=0.01). According to results of a multifactorial analysis, the most significant predictors included LV EF <50 %, MFA, and carriage of genotype А / А rs1041981 LTA.Conclusion Stratification of patients with NSTE-ACS into groups of high or low risk for having an unfavorable outcome within the next 6 years is possible using the prognostic model developed and presented in this study. The model includes the following signs: LV EF <50 %, MFA, and carriage of genotype А / А rs1041981 LTA.

Abstract The severe and acute manifestation of coronary artery disease (CAD) is acute coronary syndrome (ACS); therefore, prompt diagnosis can save lives. Cardiac biomarkers that are accepted to use in evaluating ACS are creatine kinase muscle/brain subtype (CK-MB), cardiac troponin I (CTnI), or cardiac troponin T (CTnT). However, these markers have several drawbacks, such as prolonged time to rise for prompt diagnosis and elevation in patients with chronic kidney diseases (CKD). Lately, potential, novel candidates for cardiac ischemia biomarkers have been developed, one of which is micro-ribonucleic acids (miRNAs). miRNAs are potential due to their remarkable reproducibility and stability. Several miRNAs, such as, miR-1, miR-133a, miR-133b, miR-208a, miR-208b, and miR-499a, greatly rise in concentration in the plasma or serum of patients with acute cardiac ischemia, signifying their cardiac specificity and promising biomarkers in patients with ACS. This systematic review aims to elucidate the role of cardio-specific miRNA in acute myocardial ischemia (AMI) and its relationship with other cardiac biomarkers.

A 60-year-old man presented to our emergency room with severe chest pain. Based on the electrocardiogram and elevated serum troponin T levels, acute coronary syndrome was suspected. Coronary angiography revealed total occlusion of the middle of the left anterior descending coronary artery. However, blood cell count abnormalities were not of concern. Twelve days later, the patient developed hemorrhagic infarction in the right parieto-occipital lobe. Acute coronary syndrome and cerebral hemorrhagic infarction were primarily caused by thrombus formation due to polycythemia vera (PV), based on the presence of increased blood consistency on admission. PV was diagnosed after bone marrow biopsy and genetic testing. The patient was treated with descending cell and antiplatelet therapy. Our case highlights the importance of the urgent identification of PV. When acute myocardial infarction occurs in patients with no significant risk factors for cardiovascular disease, blood routine abnormalities should be paid close attention to. If PV was diagnosed as early as possible, thrombotic and hemorrhagic complications could be prevented in the early stages.

Background: Several cardiac biomarkers are being studied to explore their potential in the prognostication of Acute Coronary Syndrome (ACS). However, there are limited studies exploring the relationship between these biomarkers and clinical, laboratory and demographic characteristics. Objective: We sought to determine the factors which influence the concentration of novel cardiac biomarkers such as Galectin-3, suppression of tumorigenicity-2 (ST-2) and Matrix Metallopeptidase-9 (MMP-9) in patients with ACS. Methods: A total of 122 patients with ACS were enrolled in the study. The study patients were categorized into two groups namely: STEMI (n=58) and NSTEMI/UA (n=64). Plasma samples were used to determine the level of biomarkers, Galectin-3 and ST-2, and serum samples were used to determine the levels of MMP-9 using the Enzyme-linked immunosorbent assay (ELISA). The association between the plasma and serum levels of biomarkers and, demographic, clinical and laboratory variables were determined. Statistical analyses for the study were performed using SPSS 16.0 software (SPSS Inc., Chicago, IL, USA). Results: Elderly aged [0.107 (0.012-0.969); p=0.047] patients had higher ST-2. Galectin-3 was higher among female patients [3.693(1.253-10.887); p=0.018] and patients with low left ventricular ejection fraction [2.882 (1.041-7.978); p=0.042]. Patients with lower body mass index [3.385 (1.241-9.231); p=0.017], diabetes [3.650 (1.302-10.237); p=0.014] and high total leukocyte count [2.900 (1.114-7.551; p=0.029] had higher MMP-9 levels. Conclusion: The concentration of galectin-3, ST-2 and MMP-9 are independently influenced by demographic, clinical and laboratory characteristics. It is estimated that these factors should be accounted for when interpreting the results of the biomarker assays.

9536 Background: To evaluate whether clinical signs or symptoms of congestive heart failure, serial assessment of systolic and diastolic cardiac function by low dose dobutamine stress echo (LDSE) and serum cardiac troponin T (cTnT) can predict doxorubicin (DOXO) cardiotoxicity. Methods: Twenty five patients with osteosarcoma enrolled in the Brazilian osteosarcoma treatment group study 2000, from january 2000 to may 2004, were studied with LDSE (>5μg/kg/min) before chemotherapy, 160 mg/m2 DOXO and after 160 mg/m2 DOXO. cTnT were measured before and during DOXO infusion. Cardiotoxicity was defined as shortening fraction (SF) less than 30% assessed by rest echo 1 to 6 months off chemotherapy. Group A comprised those without cardiotoxicity (16 patients, 10 male, 14.3 ± 4.7 years) whereas group B included those with a SF < 30% (9 patients, 6 male, 15.4 ± 3 years). Elevated serum cTnT was defined as seric levels above 0.01ng/ml. Results: Patients were submitted to a mean 3.4 LDSE and a mean of 32.5 serum cTnT. One patient (group B) presented clinical manifestation of cardiotoxicity. There was no statistical difference of elevated serum cTnT between the group B and group A (87.5% vs 46.2%; p=0,06). Left ventricular dimensions by M- MODE and transmitral Doppler inflow diastolic parameters were not significantly different between the two groups. Resting SF showed comparable values in both groups until cumulative doses of DOXO reached 160mg/m2, then the resting SF in group B was significant lower than group A (27% ± 2 and 34.1% ± 2, p<0.01). During dobutamine infusion, SF and ΔSF (dobutamine-rest) were significantly lower in group B as compared to group A at a DOXO dose 160mg/m2 (SF 36.1%±3,4 and ΔSF 2.1±2.3 vs. SF 45.2%±4.9 and ΔSF 9.4±3; p< 0.01 and p < 0.01) as well as at a DOXO dose > 160mg/m2 (30.3%±3 and 3.1±1.9 vs. 40.8%±5.9 and 7.2±4.2;p<0.01 and p<0.01). Conclusions: This study suggests that LDSE is more reliable than cTnT and clinical evaluation for predicting future subclinical cardiotoxicity,even at lower doxorubicin dose. No significant financial relationships to disclose.
