Abstract
AIM To calculate the quantitative liver-portal vein contrast ratio (Q-LPC) cut-off value based on tumour detectability by using receiver operating characteristic (ROC) curves. MATERIALS AND METHODS Seventy-four patients with tumours (46 men and 28 women; age, 71 ± 8.1 years), who underwent liver magnetic resonance imaging (MRI) using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) were enrolled. Some patients were found to have multiple tumours. In total, 102 tumour images were evaluated for quantitative liver-spleen contrast ratio (Q-LSC) and Q-LPC 10 minutes after the administration of Gd-EOB-DTPA. Q-LPC and Q-LSC were compared to assess the cut-off values and usefulness. The ROC curve was evaluated using the method for continuously distributed test results, with a free scale of 50 mm. A score of ≥30 out of 50 points was considered good. Cut-off values of Q-LPC and Q-LSC were then calculated. The areas under the ROC curve (AUCs) were also examined and compared. RESULTS The AUC-ROC for Q-LPC was 0.858 (95% confidence interval [CI], 0.783-0.933). The cut-off value was determined to be at 1.462. Sensitivity was 0.747, and specificity was 0.852 at the cut-off value. The AUC-ROC for Q-LSC was 0.710 (95% CI, 0.597-0.822). The cut-off value was at 1.543, the sensitivity was 0.560, and the specificity was 0.778 at the cut-off value. A significant difference was noted between the AUCs (p=0.0016). CONCLUSION Q-LPC can be used for hepatobiliary phase MRI evaluation.

The deeper the pouch is, the longer the radiofrequency duration and higher the radiofrequency energy needed-Cavotricuspid isthmus ablation using intracardiac echocardiography. J Arrhythm 2018; 34:410-417. [PMID: 30167012 PMCID: PMC6111476 DOI: 10.1002/joa3.12075] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Accepted: 04/25/2018] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The aim of this study was to explore whether the pouch depth influenced the radiofrequency (RF) duration and total delivered RF energy for cavotricuspid isthmus (CTI) ablation and define the cutoff value for a deep pouch-specified ablation strategy. METHODS This study included 94 atrial fibrillation (AF) patients (56 males, age 68 ± 8.0 years). With intracardiac echocardiography, the isthmus length and pouch depth were precisely measured. After a standard AF ablation, all patients underwent the CTI ablation along the lateral isthmus. If bidirectional block could not be achieved, the ablation catheter was deflected more than 90 degrees to ablate inside the pouch (knuckle-curve ablation). RESULTS Seventy-two patients (76.6%) had a sub-Eustachian pouch. Bidirectional block could be achieved in all patients. By a univariate logistic regression analysis, only the pouch depth was significantly correlated with the RF duration (P = .005) and RF energy (P = .006). A multivariate logistic regression analysis also revealed the pouch depth was the sole factor that influenced the RF duration (P = .001) and RF energy (P = .001). Among the 72 patients, 21 patients needed a knuckle-curve ablation. Using a receiver operating characteristic curve, the optimal cutoff value of the pouch depth for a knuckle-curve ablation was 3.7 mm with a sensitivity of 90% and specificity of 69%. CONCLUSIONS The sub-Eustachian pouch depth was the sole factor that influenced the RF duration and energy in the CTI ablation. If the pouch was deeper than 3.7 mm, a deep pouch-specified ablation strategy would be needed.

Abstract
BACKGROUND There is a paucity of data reporting the clinical outcomes of biodegradable polymer biolimus-eluting stent (BP-BES) compared with durable polymer everolimus-eluting stent (DP-EES) beyond 1 year after stent implantation when the polymer is fully degraded. METHODS AND RESULTS The NOBORI Biolimus-Eluting Versus XIENCE/PROMUS Everolimus-Eluting Stent Trial (NEXT) is a prospective, multicenter, randomized, open-label, noninferiority trial comparing BP-BES with DP-EES in patients scheduled for percutaneous coronary intervention using drug-eluting stent (DES) without any exclusion criteria among 98 participating centers in Japan. The trial was designed to evaluate noninferiority of BP-BES relative to DP-EES in terms of any target-lesion revascularization at 1 year and death or myocardial infarction at 3 years. Between May and October 2011, 3235 patients were randomly assigned to receive either BP-BES (1617 patients) or DP-EES (1618 patients). Complete 3-year follow-up was achieved in 97.6% of patients. At 3 years, the primary safety end point of death or myocardial infarction occurred in 159 patients (9.9%) in the BP-BES group and in 166 patients (10.3%) in the DP-EES group, demonstrating noninferiority of BP-BES relative to DP-EES (P noninferiority<0.0001 and P superiority=0.7). Cumulative incidence of target-lesion revascularization was not significantly different between the 2 groups (7.4% versus 7.1%; P=0.8). By a landmark analysis at 1 year, the cumulative incidences of death or myocardial infarction and target-lesion revascularization were also not significantly different between the 2 groups (4.6% versus 5.2%; P=0.46 and 3.3% versus 2.7%; P=0.39, respectively). CONCLUSIONS Safety and efficacy outcomes of BP-BES were non inferior to those of DP-EES 3 years after stent implantation. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Abstract
Hypoalbuminemia is an important predictor of a poor long-term prognosis in acute heart failure (AHF). However, changes in serum albumin levels in AHF have not been described to date. Therefore, we investigated the changes in serum albumin levels in patients hospitalized for AHF. This observational study included 115 consecutive patients admitted with AHF. Serum albumin was measured on days 1, 2, 4, and 7 of their hospitalization, and the changes in its levels were assessed. Cox multivariate analysis was used to compare the long-term mortality and readmission rate between 2 groups defined according to whether their serum albumin changes showed a rising pattern (serum albumin level increased from day 2 to day 7) or not. The mean serum albumin levels were 3.51 mg/dl on day 1, 3.21 mg/dl on day 2, 3.23 mg/dl on day 4, and 3.35 mg/dl on day 7 (p <0.001 by multivariate analysis of variance). The rising pattern group including 66 patients (60.6%) was independently associated with a lower mortality and readmission rate (hazard ratios 0.450 and 0.522; p = 0.01 and 0.02, respectively). Furthermore, based on multiple linear regression analysis, the changes in hemoglobin and C-reactive protein levels during days 1 to 7 were independently correlated with the changes in serum albumin levels over the same period. In conclusion, a rising pattern of serum albumin change in a patient with AHF was correlated with a good long-term prognosis. Furthermore, the change in serum albumin levels was also associated with changes in cachectic factors.

Abstract
We describe a 15-year-old postoperative girl who underwent surgical 3-dimensional mapping and ablation of hemodynamically unstable ventricular tachycardia (VT) with an on-pump beating heart surgical technique. She had previously received a tricuspid valve closure, entire right ventricular free wall resection, and finally Fontan operation with an extracardiac conduit to treat a severe Ebstein's anomaly. Activation mapping revealed a VT rotating around a large right ventricular free wall incisional scar with a narrow conduction channel between the scar and a tricuspid annulus (TA). A linear radiofrequency ablation connecting the scar and the TA terminated the VT.

Abstract
Background Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) was reported to promote better coronary and myocardial reperfusion. However, long-term mortality benefit of TA remains controversial. The objective of this study is to investigate the clinical impact of TA on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. Methods and Results The CREDO-Kyoto AMI Registry is a large-scale cohort study of acute myocardial infarction patients undergoing coronary revascularization in 2005–2007 at 26 hospitals in Japan. Among 5429 patients enrolled in the registry, the current study population consisted of 3536 patients who arrived at the hospital within 12 hours after the symptom onset and underwent primary PCI. Clinical outcomes were compared between the 2 patient groups with or without TA. During primary PCI procedures, 2239 out of 3536 (63%) patients underwent TA (TA group). The cumulative 5-year incidence of all-cause death was significantly lower in the TA group than in the non-TA group (18.5% versus 23.9%, log-rank P<0.001). After adjusting for confounders, however, the risk for all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio: 0.90, 95% CI: 0.76 to 1.06, P=0.21). The adjusted risks for cardiac death, myocardial infarction, stroke, and target-lesion revascularization were also not significantly different between the 2 groups. Conclusions Adjunctive TA during primary PCI was not associated with better 5-year mortality in STEMI patients.

Abstract
Relation of antiplatelet therapy (APT) discontinuation with the risk of serious cardiovascular events has not been fully addressed yet. This study is aimed to evaluate the risk of ischemic event after APT discontinuation based on long-term APT status of large cohort. In the CREDO-Kyoto Registry Cohort-2 enrolling 15939 consecutive patients undergoing first coronary revascularization, 10470 patients underwent percutaneous coronary intervention either with bare-metal stents (BMS) only (N=5392) or sirolimus-eluting stents (SES) only (N=5078). Proportions of patients taking dual-APT were 67.3% versus 33.4% at 1-year, and 48.7% versus 24.3% at 5-year in the SES and BMS strata, respectively. We evaluated daily APT status (dual-, single- and no-APT) and linked the adverse events to the APT status just 1-day before the events. No-APT as compared with dual- or single-APT was associated with significantly higher risk for stent thrombosis (ST) beyond 1-month after SES implantation (cumulative incidence rates beyond 1-month: 1.23 versus 0.15/0.29, P<0.001/P<0.001), while higher risk of no-APT for ST was evident only until 6-month after BMS implantation (incidence rates between 1- and 6-month: 8.43 versus 0.71/1.20, P<0.001/P<0.001, and cumulative incidence rates beyond 6-month: 0.31 versus 0.11/0.08, P=0.16/P=0.08). No-APT as compared with dual- or single-APT was also associated with significantly higher risk for spontaneous myocardial infarction (MI) and stroke regardless of the types of stents implanted. Single-APT as compared with dual-APT was not associated with higher risk for serious adverse events, except for the marginally higher risk for ST in the SES stratum. In conclusion, discontinuation of both aspirin and thienopyridines was associated with increased risk for serious cardiovascular events including ST, spontaneous MI and stroke beyond 1-month after coronary stenting.

Abstract
OBJECTIVE The use of three-dimensional T1 weighted gradient echo sequences such as the Dixon technique and the frequency-selective fat suppression (FS) technique is currently widely accepted method in MRI examinations of the liver. To assess the image qualities of the Dixon technique and the frequency-selective FS technique, the contrast-to-noise ratios (CNRs) of hepatocellular carcinoma (HCC)-to-liver and fat-to-liver were compared between the two techniques in the hepatobiliary phase (HBP) following administration of gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid. METHODS MR images of 59 patients with a total of 86 HCCs were retrospectively evaluated. Images were consecutively obtained with the Dixon and frequency-selective FS methods in the HBP and their CNRs of HCC-to-liver and fat-to-liver were compared. CNRs and contrast ratios were calculated by the mean value of the liver parenchyma, HCC, fat and standard deviation of the liver parenchyma. The Wilcoxon signed-ranks test was used for statistical analysis. RESULTS The median CNRs for the frequency-selective FS and Dixon techniques of HCC-to-liver were 4.3 and 5.4 (p < 0.01), mesenteric fat-to-liver were 9.9 and 12.8 (p < 0.01) and subcutaneous fat-to-liver were 9.9 and 13.2 (p < 0.01), respectively. CONCLUSION The Dixon technique yielded higher CNRs of HCC-to-liver than that of the frequency-selective FS technique. ADVANCES IN KNOWLEDGE There are a limited number of reports on quantitative analysis of the image qualities of the Dixon technique and the frequency-selective FS technique, particularly within the same patient and examination.

Abstract
BACKGROUND In hypertensive patients, left ventricular hypertrophy (LVH) may persist despite satisfactory blood pressure (BP) control. The efficacy of thiazide diuretics in Western countries has been reported, but whether this applies to hypertensive Japanese patients is uncertain. METHODS AND RESULTS: We randomly assigned 94 patients whose BP was poorly controlled with usual doses of angiotensin-II receptor blockers (ARB), to losartan/hydrochlorothiazide (HCTZ) fixed-dose combination vs. maximum doses of ARB. After 6 months follow-up, decrease in BP, regression of electrocardiographic LVH, and changes in laboratory measurements were examined. Although a similar decrease in BP was observed in both groups, the decrease in LV Sokolow-Lyon voltage, from 34.4±9.2 to 29.4±8.8 mm in the losartan/HCTZ vs. from 29.9±10.2 to 29.1±8.4 mm in the ARB group (P=0.0003), and the decrease in serum B-type natriuretic peptide (BNP) level, from 30.1±28.5 to 26.8±28.0 pg/ml vs. from 23.7±14.8 to 29.8±29.3 pg/ml (P=0.045) were greater in the losartan/HCTZ group. By single variable logistic regression analysis, ∆BNP (P=0.012) and treatment with losartan/HCTZ (P<0.0001) correlated with the regression of LVH. By multiple variable logistic regression analysis, both ∆BNP (P=0.035) and treatment with losartan/HCTZ (P=0.0003) remained significant. No major adverse effects were observed. CONCLUSIONS Greater regression of LVH was safely achieved with losartan/HCTZ in patients whose BP was poorly controlled with an ARB.

Abstract
The prevalence, intensity, safety, and efficacy of oral anticoagulation (OAC) in addition to dual antiplatelet therapy (DAPT) in "real-world" patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) have not yet been fully evaluated. In the Coronary REvascularization Demonstrating Outcome Study in Kyoto registry cohort-2, a total of 1,057 patients with AF (8.3%) were identified among 12,716 patients undergoing first PCI. Cumulative 5-year incidence of stroke was higher in patients with AF than in no-AF patients (12.8% vs 5.8%, p <0.0001). Although most patients with AF had CHADS2 score ≥2 (75.2%), only 506 patients (47.9%) received OAC with warfarin at hospital discharge. Cumulative 5-year incidence of stroke in the OAC group was not different from that in the no-OAC group (13.8% vs 11.8%, p = 0.49). Time in therapeutic range (TTR) was only 52.6% with an international normalized ratio of 1.6 to 2.6, and only 154 of 409 patients (37.7%) with international normalized ratio data had TTR ≥65%. Cumulative 5-year incidence of stroke in patients with TTR ≥65% was markedly lower than that in patients with TTR <65% (6.9% vs 15.1%, p = 0.01). In a 4-month landmark analysis in the OAC group, there was a trend for higher cumulative incidences of stroke and major bleeding in the on-DAPT (n = 286) than in the off-DAPT (n = 173) groups (15.1% vs 6.7%, p = 0.052 and 14.7% vs 8.7%, p = 0.10, respectively). In conclusion, OAC was underused and its intensity was mostly suboptimal in real-world patients with AF undergoing PCI, which lead to inadequate stroke prevention. Long-term DAPT in patients receiving OAC did not reduce stroke incidence.

Abstract
Treatment of coronary artery disease has significantly changed over the past decade including an introduction of drug-eluting stents and a more stringent adherence to evidence-based medications. However, the impact of these advanced treatment methods on the practice patterns and long-term outcomes in patients undergoing coronary revascularization in the real world has not been yet fully evaluated. The present study population consisted of the 2 groups of patients who underwent their first coronary revascularization in the Coronary REvascularization Demonstrating Outcome Study in Kyoto Registry Cohort-1 (bare-metal stent era: January 2000 to December 2002, n = 8,986) and Cohort-2 (drug-eluting stent era: January 2005 to December 2007, n = 10,339). Compared with Cohort-1, the proportion of patients treated with percutaneous coronary intervention significantly increased in Cohort-2 (73% vs 81%, p <0.001), particularly for 3-vessel disease (50% vs 61%, p <0.001) and left main disease (18% vs 36%, p <0.001). Evidence-based medications were more frequently used in Cohort-2. The cumulative 2-year incidence of and the adjusted risk for all-cause death were not significantly different between Cohort-1 and Cohort-2 (6.2% vs 6.4%, p = 0.69, and hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.81 to 1.03, p = 0.15). Adjusted risks for both myocardial infarction and repeated coronary revascularization were significantly reduced in Cohort-2 compared with Cohort-1 (HR 0.80, 95% CI 0.67 to 0.96, p = 0.02, and HR 0.73, 95% CI 0.69 to 0.77, p <0.001, respectively). In conclusion, despite changes in treatment methods over time, the long-term mortality of patients undergoing coronary revascularization in the real-world clinical practice has not been changed, although there was a significant reduction of myocardial infarction and repeated coronary revascularization.

Biodegradable polymer biolimus-eluting stent versus durable polymer everolimus-eluting stent: a randomized, controlled, noninferiority trial. J Am Coll Cardiol 2013; 62:181-190. [PMID: 23684673 DOI: 10.1016/j.jacc.2013.04.045] [Citation(s) in RCA: 173] [Impact Index Per Article: 15.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2013] [Revised: 03/24/2013] [Accepted: 04/16/2013] [Indexed: 02/06/2023]
Abstract
OBJECTIVES NEXT (NOBORI Biolimus-Eluting Versus XIENCE/PROMUS Everolimus-Eluting Stent Trial) was designed for evaluating the noninferiority of a biolimus-eluting stent (BES) relative to an everolimus-eluting stent (EES) in terms of target lesion revascularization (TLR) at 1 year. BACKGROUND Efficacy and safety data comparing biodegradable polymer BES with durable polymer cobalt-chromium EES are currently limited. METHODS The NEXT trial is a prospective, multicenter, randomized, open-label, noninferiority trial comparing BES with EES. Between May and October 2011, 3,235 patients were randomly assigned to receive either BES (n = 1,617) or EES (n = 1,618). RESULTS At 1 year, the primary efficacy endpoint of TLR occurred in 67 patients (4.2%) in the BES group, and in 66 patients (4.2%) in the EES group, demonstrating noninferiority of BES relative to EES (p for noninferiority <0.0001, and p for superiority = 0.93). Cumulative incidence of definite stent thrombosis was low and similar between the 2 groups (0.25% vs. 0.06%, p = 0.18). An angiographic substudy enrolling 528 patients (BES: n = 263, and EES: n = 265) demonstrated noninferiority of BES relative to EES regarding the primary angiographic endpoint of in-segment late loss (0.03 ± 0.39 mm vs. 0.06 ± 0.45 mm, p for noninferiority <0.0001, and p for superiority = 0.52) at 266 ± 43 days after stent implantation. CONCLUSIONS One-year clinical and angiographic outcome after BES implantation was noninferior to and not different from that after EES implantation in a mostly stable coronary artery disease population. One-year clinical outcome after both BES and EES use was excellent, with a low rate of TLR and extremely low rate of stent thrombosis.

Abstract
BACKGROUND Urine albumin excretion is an important predictor of adverse cardiovascular events in various populations. Its correlation in patients with acute heart failure has not been described. METHODS AND RESULTS This prospective, observational study included 115 patients presenting with acute heart failure. The urine albumin/creatinine ratio (UACR) was measured from spot urine samples collected on days 1 and 7 of hospitalization. Median UACR decreased from 83 to 22 mg/gCr on days 1 and 7, respectively (P<0.0001). The proportion of patients with normoalbuminuria (UACR <30 mg/gCr) increased from 31% on day 1 to 60% on day 7, whereas the proportion with microalbuminuria (UACR between 30 and 299 mg/gCr) and macroalbuminuria (UACR ≥300 mg/gCr) decreased, respectively, from 42% and 27% on day 1 to 30% and 10% on day 7 (P<0.0001). These changes in UACR were correlated with changes in serum bilirubin and N-terminal pro b-type natriuretic peptide concentrations (correlation coefficients 1.087 and 0.384, respectively; 95% confidence interval, 0.394-1.781 and 0.087-0.680, respectively; and P=0.003 and 0.013, respectively), although they were not correlated with change in estimated glomerular filtration rate. CONCLUSIONS In this sample of patients presenting with acute heart failure, urine albumin excretion was often increased at admission to the hospital and decreased significantly within 7 days of treatment. The decrease was correlated with serum N-terminal pro b-type natriuretic peptide and bilirubin concentrations, although neither with baseline nor with changes in indices of renal function.

Abstract
The Joint European Society of Cardiology-American College of Cardiology Foundation-American Heart Association-World Heart Federation Task Force for the Redefinition of Myocardial Infarction recommends cardiac troponin (cTn)-T as a first-line biomarker, and suggests the use of the 99th percentile of a reference population with acceptable precision (i.e. a coefficient of variance≤10%) as a cut-off for the diagnosis of acute myocardial infarction. Recently developed troponin assays fulfill this analytical precision. While conventional cTnT assays have often been used as a positive or negative categorical variable, stepwise rises in high sensitivity (Hs)-cTnT in patients presenting with chronic heart failure (HF) have been associated with a progressive increase in the incidence of cardiovascular events. Similar observations have been made in the general population. Hs-cTnT at baseline and during follow-up is a powerful predictor of cardiac events in patients with HF and in the general population. Whether it is the ideal biomarker remains to be confirmed, however. We review the potential contributions of TnT assays in the assessment of risk of HF, in HF, and in myocardial diseases that cause HF.

Abstract
BACKGROUND Several recent randomized trials comparing everolimus-eluting stent (EES) and sirolimus-eluting stent (SES) reported similar outcomes. However, only 1 trial was powered for a clinical end point, and no trial was powered for evaluating target-lesion revascularization. METHODS AND RESULTS Randomized Evaluation of Sirolimus-eluting versus Everolimus-eluting stent Trial is a prospective multicenter randomized open-label trial comparing EES with SES in Japan. The trial was powered for evaluating noninferiority of EES relative to SES in terms of target-lesion revascularization. From February and July 2010, 3197 patients were randomly assigned to receive either EES (1597 patients) or SES (1600 patients). At 1 year, the primary efficacy end point of target-lesion revascularization occurred in 65 patients (4.3%) in the EES group and in 76 patients (5.0%) in the SES group, demonstrating noninferiority of EES to SES (P(noninferiority)<0.0001, and P(superiority)=0.34). Cumulative incidence of definite stent thrombosis was low and similar between the 2 groups (0.32% versus 0.38%, P=0.77). An angiographic substudy enrolling 571 patients (EES, 285 patients and SES, 286 patients) demonstrated noninferiority of EES relative to SES regarding the primary angiographic end point of in-segment late loss (0.06±0.37 mm versus 0.02±0.46 mm, P(noninferiority)<0.0001, and P(superiority)=0.24) at 278±63 days after index stent implantation. CONCLUSIONS One-year clinical and angiographic outcome after EES implantation was noninferior to and not different from that after SES implantation in a stable coronary artery disease population with relatively less complex coronary anatomy. One-year clinical outcome after both EES and SES use was excellent with a low rate of target-lesion revascularization and a very low rate of stent thrombosis.

Abstract
A 65-year-old woman presenting with cardiac sarcoidosis underwent serial measurement of her serum high-sensitivity cardiac troponin I (Hs-cTnI) and N-terminal proB-type natriuretic peptide (NT-proBNP) concentrations. She was treated with 1,000 mg/day methylprednisolone for 2 days, which was subsequently replaced by 30 mg/day prednisolone, and decreased to 20 mg/day at the time of discharge, 2 months later. Her echocardiogram showed improvements in the left ventricular systolic and diastolic function, along with a decrease in the concentration of Hs-cTnI and NT-proBNP. This is the first report suggesting that Hs-cTnI might be a reliable means of assessing the effects of treatment of cardiac sarcoidosis.

Abstract
BACKGROUND N-terminal proBNP (NT-proBNP) is widely used as a diagnostic biomarker and for the risk stratification of patients with heart failure (HF). Its role in the evaluation of patients with essential hypertension (EHT) is less clear. We examined the relationship between NT-proBNP concentrations and various clinical characteristics in hypertensive patients without HF. METHODS This study included 186 consecutive patients with EHT and no history of HF, ischemic heart disease, or atrial fibrillation. Single and multiple variable regression analyses were performed in search of clinical correlates of NT-proBNP concentrations. RESULTS In patients with EHT, median serum concentration of NT-proBNP was 73 pg/ml, and interquartile range (IQR) was 40-128 pg/ml. NT-proBNP was significantly higher (P<0.001) in women (87 pg/ml; IQR 55-137 pg/ml) than in men (52 pg/ml; IQR 24-115 pg/ml). Age (r=0.371, P<0.001), precordial QRS voltage (r=0.223, P<0.001), hemoglobin (Hgb) concentration, (r=-0.208, P=0.023) and estimated glomerular filtration rate (r=-0.139, P=0.044) were correlated with log-transformed NT-proBNP by multiple variable analysis. In men, age (r=0.453, P<0.001) and QRS voltage (r=0.283, P=0.004), and in women age (r=0.299, P=0.006), QRS voltage (r=0.212, P=0.019), Hgb (r=-0.182, P=0.049), and estimated glomerular filtration rate (r=-0.272, P=0.009) were correlated with serum concentrations of NT-proBNP. CONCLUSIONS Age, gender, Hgb, left ventricular hypertrophy and renal function were correlated with NT-proBNP in patients with EHT.

Abstract
BACKGROUND Interleukin (IL)-6 has recently been shown to have negative inotropic effects, and several studies have reported increases in circulating concentrations of this cytokine in patients with depressed left ventricular ejection fraction and chronic left heart failure. However, most previous clinical studies have measured cytokines in compensated chronic heart failure. HYPOTHESIS The purpose of this study was to examine the temporal evolution of circulating concentrations of C-reactive protein (CRP) and cytokines in patients with cardiomyopathy and acute cardiac decompensation, free of infection and unstable angina. METHODS The time course of circulating concentrations of CRP, an anti-inflammatory cytokine interleukin (IL)-4, and a proinflammatory cytokine IL-6 were studied in eight patients with cardiomyopathy and acute cardiac decompensation in the absence of infection or unstable angina. Control samples were obtained from eight age-matched asymptomatic subjects. RESULTS Increased circulating concentrations of CRP (2.6 +/- 0.8 mg/dl), IL-4 (164.6 + 36.5 pg/ml), and IL-6 (17.1 +/- 5.1 pg/ml) were found in all eight patients during acute cardiac decompensation; these values decreased significantly with the resolution of symptoms of cardiac decompensation (0.5 +/- 0.1 mg/dl, 77.8 +/- 23.6 pg/ml, 2.3 +/- 0.1 pg/ml, respectively, p < 0.05 for both). There was a significant correlation between peak CRP and peak IL-6 (p < 0.05). CONCLUSIONS In patients with acute left heart decompensation in the absence of infection or coronary events, CRP, IL-4, and IL-6 increased and returned toward normal levels as the symptoms of heart failure resolved. Since the changes in concentrations of CRP, IL-4, and IL-6 in patients with heart failure are dynamic, the distinction between compensated and decompensated state is important when discussing the significance of acute reactive proteins or cytokines in the pathogenesis of heart failure.

Abstract
BACKGROUND Subclinical myocyte injury plays an important role in the progression of congestive heart failure. However, the clinical and hemodynamic factors that influence the concentrations of biomarkers of myocyte injury have not been clarified. METHODS Blood was sampled during diagnostic cardiac catheterization from 108 consecutive patients without acute coronary syndrome and acute cardiac decompensation. The serum concentrations of B-type natriuretic peptide (BNP), cardiac troponin I (cTnI), creatine kinase (CK)-MB, and myoglobin were measured simultaneously by high sensitive PATHFAST assay. Single and multiple variable regression analyses were carried out in search of correlations between clinical and hemodynamic variables and concentrations of biomarkers. RESULTS By multiple variable analysis, hemoglobin concentration, pulmonary capillary wedge pressure (PCWP), left ventricular (LV) ejection fraction, and estimated glomerular filtration rate (GFR) were independently correlated with a BNP concentration ≥ median 72.1 pg/ml. The only factors independently correlated with a concentration of cTnI ≥ median 0.01 ng/ml were PCWP and estimated GFR. Cardiac index emerged as a single, powerful, independent correlate of CK-MB concentration ≥ median 0.66 ng/ml, and estimated GFR emerged as a single independent correlate of myoglobin concentration ≥ median 40.1 ng/ml. CONCLUSIONS Clinical and hemodynamic factors influence the concentrations of BNP, cTnI, CK-MB, and myoglobin. These factors should be considered when interpreting the concentrations of these biochemical markers.
