Abstract Aims: The level of serum carbohydrate antigen 125 (CA 125) elevated is a common finding in patients with cardiac amyloidosis in clinical practice. It is unclear whether CA 125 is correlated with cardiac amyloidosis. The aim of this study was to systematically evaluate the clinical implications of CA 125 elevation in patients with cardiac amyloidosis.Methods and Results: We enrolled 101 patients diagnosed with cardiac amyloidosis at the Second Xiangya Hospital, 41 patients with acute decompensated heart failure (AHF) and 39 patients with multiple myeloma (MM) who were confirmed to have no cardiac amyloidosis served as control group, respectively. In 101 patients with cardiac amyloidosis, 58 (57%) patients had elevated serum CA 125 levels, which the mean age was 61.2 ± 11.4 years. Patients with high CA 125 were more likely to present with polyserositis ( 79.3% vs 60.5%, p = 0.03) , higher levels of hemoglobin (117.22 ± 21.87 g/L vs. 106.07 ± 25.15 g/L, p = 0.01), serum potassium (4.17 ± 0.49 mmol/L vs. 3.98 ± 0.41 mmol/L, p = 0.05), low density lipoprotein-cholesterol (2.98 ± 1.65 mmol/L vs. 2.22 ± 1.10 mmol/L, p = 0.01), and cardiac troponin T (115 pg/mL vs. 59.52 pg/mL, p = 0.005) . The serum CA 125 levels were significantly higher in cardiac amyloidosis than AHF and MM. The median overall survival for patients with elevated and normal serum CA125 were 5 and 20 months, respectively (p = 0.012). According to multivariate Cox hazard analysis, CA 125 (HR 1.002, 95%CI 1.000-1.004, p = 0.020) contributed to all-cause mortality. The time-dependent receiver operating characteristic was used to reflect the accuracy of different biomarkers in predicting overall survival at various time points by the area under the curve (AUC). CA 125 has no worse prediction accuracy than cardiac troponin T, NT-proBNP and LDH according to the AUC.Conclusions: The prevalence of elevated serum CA 125 levels is more than 50% in patients with cardiac amyloidosis. As an independent prognostic predictor, highly serum CA 125 values indicated the lower overall survival and the accuracy of predicting prognosis was not inferior to the other biomarkers.

Background and Aims: Patients with light-chain cardiac amyloidosis (AL-CA) are characterized by high levels of serum carbohydrate antigen 125 (CA 125). However, studies have not explored the correlation between CA 125 and AL-CA. The aim of this study was to explore the clinical implications of an increase in CA 125 in patients with AL-CA.Methods and Results: A total of 95 patients diagnosed with AL-CA at the Second Xiangya Hospital were enrolled in this study. Out of the 95 patients with AL-CA, 57 (60%) patients had elevated serum CA 125 levels. The mean age was 59.7 ± 10.0 years with 44 (77.2%) men in the high serum CA 125 group, and 61.8 ± 9.6 years with 28 (73.7%) men in the normal group. Patients with high CA 125 showed higher rates of polyserositis (79.3% vs. 60.5%, p = 0.03), higher levels of hemoglobin (117.4 ± 21.9 g/L vs. 106.08 ± 25.1 g/L, p = 0.03), serum potassium (4.11 ± 0.47 mmol/L vs. 3.97 ± 0.40 mmol/L, p = 0.049), low-density lipoprotein-cholesterol (3.0 ± 1.6 mmol/L vs. 2.3 ± 1.10 mmol/L, p = 0.01), and cardiac troponin T (96.0 pg/mL vs. 91.9 pg/mL, p = 0.005). The median overall survival times for patients with high or normal serum CA 125 were 5 and 25 months, respectively (p = 0.045). Multivariate Cox hazard analysis showed that treatment without chemotherapy (HR 1.694, 95% CI 1.121–2.562, p = 0.012) and CA 125 (HR 1.002, 95% CI 1.000–1.004, p = 0.020) was correlated with high all-cause mortality. The time-dependent receiver operating characteristic (t-ROC) curve showed that the prediction accuracy of CA 125 was not inferior to that of cardiac troponin T, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and lactate dehydrogenase (LDH) based on the area under the curve.Conclusions: CA 125 is a novel prognostic predictor. High serum CA 125 values are correlated with low overall survival, and the accuracy of predicting prognosis is similar to that of traditional biomarkers in AL-CA.

Background: Cardiac amyloidosis (CA) is an important differential diagnosis in patients with myocardial hypertrophy. The precise diagnosis of CA requires endomyocardial biopsy to demonstrate amyloid deposition, but this procedure is relatively invasive and cannot be performed routinely. Therefore, it is important to increase pretest probability of CA in patients with myocardial hypertrophy by noninvasive modalities. Because it is well known that cardiac troponin level is elevated in patients with CA, we hypothesized that increased level of cardiac troponin T contributes to diagnosis of CA in patients with myocardial hypertrophy using high sensitive assay (hs-TnT). Methods and Results: Among nonischemic patients with myocardial hypertrophy (interventricular septal thickness≧ 12 mm), hs-TnT level was measured in 28 CA patients (senile systemic amyloidosis: 13, AL amyloidosis: 14, familial amyloidosis: 1) proven amyloidosis pathologically and 29 non-CA patients proven by endomyocardial biopsy. It was significantly higher in CA patients than non-CA patients (0.075 [0.047-0.116] ng/ml vs. 0.013 [0.009-0.019] ng/ml; p<0.001: Figure). Receiver operating characteristic analysis selected 0.030 ng/ml as the best cutoff value of diagnosis for CA, with a sensitivity and specificity of 96% and 93%, respectively and area under the curve of 0.98 (95% confidence interval 0.94 to 1.00, p<0.001). Conclusions: Increased level of hs-TnT (>0.030 ng/ml) is highly suggestive of CA in patients with myocardial hypertrophy. These patients need additional diagnostic approach for CA.

Matrix metalloproteinases (MMPs), activated by oxidative stress, play a key role during cardiac remodeling. In the present study we aimed to assess the role of MMPs in experimental cardiomyopathy induced by repeated 10-week administration of daunorubicin (3 mg/kg i.v.) to rabbits. In the daunorubicin group, the plasma cardiac troponin T levels (cTnT – a marker of myocardial necrosis) were significantly increased (p<0.05), commencing with the 8th administration compared with the controls. The amount of collagen (an estimate of fibrosis) was also significantly higher in the daunorubicin group (13.39 ± 0.97 mg/g wet weight) compared to the control group (10.03 ± 0.65 mg/g wet weight). In both groups, the LV MMP-activity was observed only in the gelatine substrate in the 70 kDa region (MMP-2), while no MMPs activities were detectable either in the casein or collagen containing zymograms. At the end of the experiment, the MMP- 2 activity was slightly up-regulated (by 16 %) compared with the controls.

Abstract Background Cardiac amyloidosis (CA) is characterized by the accumulation of misfolded proteins into amyloid fibrils, leading to cardiomyocyte toxicity, extracellular volume expansion and ventricular pseudohypertrophy. As a consequence of such processes, natriuretic peptides and cardiac troponins are chronically elevated in CA and hold significant prognostic value. The diagnostic yield of these biomarkers for CA has never been explored so far. Methods Plasma levels of N-terminal fraction of pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) were measured in 230 patients referred to a tertiary centre with the clinical suspicion of cardiac amyloidosis. The final diagnosis was established according to current protocols, which include clinical, electrocardiographic, biohumoral, instrumental (echocardiography, cardiac magnetic resonance, diphosphonate scintigraphy), and biopsy examinations. Results Patients were aged 79 (interquartile interval 73–83) years and were predominantly males (n=147, 64%). Mean left ventricular (LV) ejection fraction was 55% (48–62%), and mean LV mass indexed was 150 (120–178) g/m2. CA was confirmed in 86 patients (37%), who had either light chain (AL) amyloidosis (n=25, 29%) or transthyretin (ATTR) amyloidosis (n=61, 71%). Alternative diagnoses were hypertensive cardiopathy (n=69, 48%), valvular disease (n=27, 19%), hypertrophic cardiomyopathy (n=18, 13%), or left ventricular hypertrophy with unknown or multifactorial mechanisms. Patients with CA showed higher NT-proBNP (5507 ng/L [2348–10326] vs. 1332 [392–3752], p<0.001) and hs-cTnT (65 ng/L [48–114] vs. 35 [21–52], p<0.001) than those without CA. The area under the curve (AUC) values for NT-proBNP and hs-cTnT were 0.712 and 0.775 respectively (p=0.062 for the difference). The combination of the two biomarkers improved discrimination over NT-proBNP alone (p=0.011), but not over hs-cTnT (p=0.470) (Figure). A NT-proBNP level <600 ng/L or a hs-cTnT level <17 ng/L were optimal for ruling out amyloidosis, with a negative predictive value of 95% in both cases. Patients with AL amyloidosis had higher NT-proBNP and hs-cTnT than those with ATTR (10809 ng/L [6292–17483] vs. 3084 [1841–7624], p=0.014; 130 ng/L [64–211] vs. 61 [48–95], p=0.006). The difference was even more prominent when biomarker levels were normalized for LV mass (NT-proBNP/LV mass, 33.9 ng/L/g [20.4–53.8] vs. 10.0 [5.8–23.5], p=0.002; hs-cTnT/LV mass, 0.48 ng/L/g [0.25–0.71] vs. 0.19 [0.14–0.26], p=0.001). NT-proBNP and hs-cTnT could effectively discriminate patients with AL amyloidosis among subjects with clinical suspicion of CA (AUC values of 0.787 and 0.805 respectively) (Figure). Figure 1 Conclusions Plasma NT-proBNP and hs-cTnT have diagnostic value in patients with suspected CA. In the subgroup with CA, both biomarkers are higher in patients with AL amyloidosis even when normalizing for LV mass, possibly because of a greater cardiotoxic effect of light-chain fibrils.

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.
