Abstract
BACKGROUND There are many detectable changes in circulating biomarkers in the setting of myocardial ischemia. We hypothesize that there are associated changes in circulating B-type natriuretic peptide (BNP) level after stress-induced myocardial ischemia, which can be used for emergency department (ED) acute coronary syndrome (ACS) risk stratification. METHODS In a prospective study, we enrolled 340 patients over the age of 30 receiving an exercise echocardiography stress test in an ED observational unit for suspected ACS. We collected blood samples at baseline and at 2 and 4 h post-stress test, measuring the relative and absolute changes (stress-delta) in plasma BNP concentrations. In addition, patients were contacted at 90 days and at 1 year posttest for a follow-up. We calculated the diagnostic test characteristics of stress-delta BNP for a composite outcome of ischemic imaging on stress echocardiogram, nonelective percutaneous coronary intervention, coronary artery bypass graft surgery, subsequent acute myocardial infarction, or cardiac death at 1 year via a logistic regression. We analyzed the 2-h BNP concentrations using an ANOVA model to adjust for the baseline BNP level. RESULTS Baseline and 2-h post-stress BNP were both higher in the positive outcome group, but the stress-delta BNP was not. Stress-delta BNP had a sensitivity and specificity, respectively, of 53% and 76% at 2 h and 67% and 68% at 4 h. It was noted that patients with the composite outcome had a higher baseline BNP level. CONCLUSIONS BNP stress-deltas are poor diagnostic means for ACS risk stratification, but resting BNP remains a promising prognostic tool for ED patients with suspected ACS.

[PMID: 35716940 DOI: 10.1016/j.ijcard.2022.06.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 04/18/2022] [Accepted: 06/10/2022] [Indexed: 11/05/2022]
Abstract
INTRODUCTION The evidence about the use of natriuretic peptides (NP) to predict mortality in the pre-hospital setting is limited. The main objective of this study is to assess the ability of point-of-care testing (POCT) N-terminal portion of B-type natriuretic peptide (NT-proBNP) to predict 2-day in-hospital mortality of acute cardiovascular diseases (ACVD). METHODS We conducted a multicentric, prospective, observational study in adults with ACVD transferred by ambulance to emergency departments (ED). The primary outcome was 2-day in-hospital mortality. The discrimination capacity of the NT-proBNP was performed through a prediction model trained using a derivation cohort and evaluated by the area under the curve (AUC) of the receiver operating characteristic on a validation cohort. RESULTS A total of 1006 patients were recruited. The median age was 75 (IQR 63-84) years and 421 (41.85%) were females. The 2-day in-hospital mortality was 5.8% (58 cases). The predictive validity of NT-proBNP, for 2-day mortality reached the following AUC: 0.823 (95%CI: 0.758-0.889, p < 0.001), and the optimal specificity and sensitivity were 73.1 and 82.7. Predictive power of NT-proBNP obtained an AUC 0.549 (95%CI: 0.432-0.865, p 0.215) for acute heart failure, AUC 0.893 (95%CI: 0.617-0.97, p < 0.001) for ischemic heart disease, AUC 0.714 (95%CI: 0.55-0.87, p = 0.0069) for arrhythmia and AUC 0.927 (95%CI: 0.877-0.978, p < 0,001) for syncope. CONCLUSION POCT NT-proBNP has proven to be a strong predictor of early mortality in ACVD, showing an excellent predictive capacity in cases of syncope. However, this biomarker does not appear to be useful for predicting outcome in patients with acute heart failure.

Abstract
Chest pain is a frequent cause for emergency department visits and inpatient evaluation, with particular concern for acute coronary syndrome as an etiology, since cardiovascular disease is the leading cause of death in the United States. Although history-based, electrocardiographic, and laboratory evaluations have shown promise in identifying coronary artery disease, early accurate diagnosis is paramount and there is an important role for imaging examinations to determine the presence and extent of anatomic coronary abnormality and ischemic physiology, to guide management with regard to optimal medical therapy or revascularization, and ultimately to thereby improve patient outcomes. A summary of the various methods for initial imaging evaluation of suspected acute coronary syndrome is outlined in this document. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
BACKGROUND Irreversible electroporation (IRE) is a novel tumor ablative therapy technique, using electric fields to induce apoptosis in target tissues. Whether these electric pulses of high field strength can cause cardiac damage and/or ablation-induced arrhythmias is unclear. OBJECTIVE The purpose of this study was to systematically evaluate the safety of electrocardiogram (ECG)-gated IRE with regard to cardiac side effects. METHODS In all patients, 12-lead ECG and signal-averaged ECG (SAECG) recordings were performed before and after IRE and 24-hour Holter recording on the day of the IRE procedure. Venous blood samples (N-terminal pro-brain-type natriuretic peptide [NT-proBNP], high-sensitive troponin I [hsTnI]) were obtained before and 4 and 16 hours after the procedure. Patients with abnormal findings were reevaluated after 3 months. RESULTS In total, 26 patients with an oncologic indication for IRE (11 females, mean age 62.9 years) were prospectively enrolled. Nine patients (34.6%) showed an increase in hsTnI and 21 patients (80.8%) an increase in NT-proBNP after ablation. Fifteen patients (57%) developed arrhythmias related to the procedure. One patient, in whom hsTnI and NT-proBNP had increased, developed multiple, nonsustained ventricular tachycardia events. In another patient, atrial fibrillation was triggered twice in 2 separate procedures. Twelve patients had clinically benign arrhythmias. SAECG was negative in all patients. CONCLUSION Subclinical myocardial injury and nonfatal cardiac arrhythmias can occur in the context of IRE treatment. Although no sustained cardiac injuries could be found at 3-month follow-up, we propose implementation of a cardiac safety algorithm consisting of cardiac biomarkers and ECG monitoring when IRE is conducted.

Abstract
The acute coronary syndrome (ACS) represents a diagnostic challenge: on the one hand patients need to be quickly identified to initiate treatment and on the other hand early exclusion of patients without ACS is important to relieve patient stress as well as overcrowded emergency departments. A growing number of biomarkers are becoming available to aid physicians with this task. This review gives an overview of the current research concerning early exclusion with an emphasis on the clinically most important biomarker: cardiac troponin.

Abstract
Biomarkers complement clinical assessment and the 12-lead ECG in the diagnosis, risk stratification, triage, and management of patients with suspected acute coronary syndrome (ACS). While there is broad consensus that cardiac troponin (cTn) I or T is the preferred biomarker in clinical practice, important uncertainties remain regarding the value of high-sensitivity cTn assays, their best clinical use including the most appropriate timing of serial measurements, as well as the added value of other biomarkers reflecting and quantifying other pathophysiological signals including copeptin and natriuretic peptides. This review will address these aspects with a focus on the diagnostic application of biomarkers, as they are associated with immediate therapeutic consequences. In addition, this review will briefly highlight that increased diagnostic accuracy offered by high-sensitivity cTn assays has contributed to improve our understanding of the incidence, pathophysiology, and mortality of the two distinct components currently summarized under the term ACS: acute myocardial infarction and unstable angina.

Abstract
The aim of this study was to detect early changes (within 1–4 h) in the brain natriuretic peptide (BNP) levels of rats with acute myocardial infarction (AMI). A total of 35 Wistar rats were established as models of AMI and 30 sham-operated rats were used as the control group. The myocardia of the two groups were observed using a transmission electron microscope (TEM) prior to and following surgery. A double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) was used to detect the serum BNP and cardiac troponin I (cTnI) concentrations before and 1–4 h after surgery. Following the successful establishment of the AMI models, serum BNP concentrations were significantly increased within 1–4 h compared with the values prior to surgery and with those of the control group (all P<0.01). The serum BNP concentration reached its highest level 2 h after AMI (532.25±15.16 ng/l). No significant changes were observed in the cTnI serum levels of the AMI group within 1–4 h compared with the values before AMI and those in the control group (all P>0.05). In the 1–4 h following the establishment of the AMI model, significant positive correlations were identified between the serum BNP concentrations and the size of the AMI and the most marked correlation occurred 2 h after AMI (r=0.72, P<0.05). No significant differences were noted in the serum concentrations of BNP and cTnI in the control group prior to and following the sham surgery (all P>0.05). BNP may be used as a blood marker for the early diagnosis of AMI, particularly 1–4 h after the onset of AMI, and to predict the size of the infarct area.

Abstract
BACKGROUND The purpose of this study was to investigate the utility of mid-regional pro-adrenomedullin (MR-proADM) in the early diagnosis and risk stratification of patients with acute chest pain in comparison with established and novel biomarkers and risk scores. METHODS In this prospective, observational, international, multi-center trial (APACE), MR-proADM was determined in 1179 unselected patients with acute chest pain. Patients were followed for 24 months. RESULTS MR-proADM concentrations at presentation were higher in patients with AMI (median: 0.78 nmol/l, IQR 0.60-1.13) than in patients with other diagnoses (0.64 nmol/l, IQR 0.49-0.86 nmol/l; p<0.001). The diagnostic accuracy of MR-proADM for AMI as quantified by the area under the receiver operating characteristic curve (AUC) was 0.66. Adding MR-proADM to hs-cTnT could not improve its diagnostic accuracy for AMI (p=0.431). Seventy-six percent of all deaths occurred in the fourth quartile of MR-proADM (>0.90 nmol/l). Adding MR-proADM to the TIMI-score (AUC 0.87) predicted 1-year mortality more accurately than the TIMI-score alone (AUC 0.82; p<0.001). Net reclassification improvement (TIMI vs. additionally MR-proADM) amounted to 0.137 (p=0.012). MR-proADM had higher prognostic accuracy as compared to hs-cTnT in patients with AMI (p=0.015) and in those without AMI (p=0.003). MR-proADM at presentation was tantamount to GRACE score and BNP as to its prognostic accuracy for mortality. The AUC for the prediction of cardiovascular events amounted to 0.63. CONCLUSIONS While MR-proADM does not have clinical utility in the early diagnosis of AMI or predicting cardiovascular events in patients with acute chest pain, it may provide prognostic value for all-cause mortality.

Abstract
BACKGROUND Compared to troponin alone, a dual-marker strategy with natriuretic peptides may improve acute coronary syndrome (ACS) diagnosis with a single blood draw and provide physiologic information regarding underlying heart disease. We evaluate the value of adding natriuretic peptides (myocyte stress markers) to troponins (myocardial injury markers) for diagnosing ACS in emergency department patients with chest pain. METHODS In 328 patients (53 ± 12 years, 63% men) with an initially negative conventional troponin and nonischemic electrocardiogram who underwent 64-slice cardiac computed tomography (CT), we measured conventional troponin-T (cTnT), high-sensitivity troponin-T (hsTnT), N-terminal pro-B type natriuretic peptide, and mid-regional pro-atrial natriuretic peptide. ACS was defined as myocardial infarction or unstable angina. CT was evaluated for coronary plaque, stenosis, and regional wall motion abnormality. RESULTS Patients with ACS (n = 29, 9%) had higher concentrations of each biomarker compared to those without (all P < .01). Adding natriuretic peptides, especially N-terminal pro-B type natriuretic peptide, to both cTnT or hsTnT improved the C-statistics and net reclassification index for ACS, largely driven by correctly reclassifying events. Dual-negative marker results improved sensitivity (cTnT 38% to 83%-86%, hsTnT 59% to 86%-90%; all P < .01) and negative predictive value (cTnT 94% to 97%-98%, hsTnT 96% to 97%-98%) for ACS. Patients with dual-negative markers had the lowest percentage of CT coronary plaque, stenosis, and regional wall motion abnormality (all P-trend <.001). CONCLUSION Among emergency department patients with low-intermediate likelihood of ACS, combining natriuretic peptides with either conventional or highly-sensitive troponin improved discriminatory capacity and allowed for better reclassification of ACS, findings supported by structural and functional CT results.

Abstract
Either B-type natriuretic peptide (BNP) or NT-proBNP may be used as a diagnostic, screening, prognostic and therapeutic tool for CHF. The Food and Drug Administration (FDA) cleared the cut-off point for BNP at 100 pg/mL, and that of NT-proBNP at 125 pg/mL for patients <75 years and 450 pg/mL for those >75. A steadily rising titre even below the cut-off value should be raised as a concern as heart failure is progressive if left untreated and may result in cardiac death. Both biomarkers are also featured in lab investigations for patients with acute coronary syndrome (ACS).
