Increased levels of NT-proBNP and troponin T 2 years after coronary artery bypass grafting complicated by mediastinitis. Front Cardiovasc Med 2023; 10:1008825. [PMID: 36824453 PMCID: PMC9941316 DOI: 10.3389/fcvm.2023.1008825] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 01/16/2023] [Indexed: 02/10/2023] Open
Abstract
Background Mediastinitis after coronary bypass grafting (CABG) increases the risk of the internal mammary artery (IMA) graft obstruction, and has a detrimental effect on long-term survival. The pathogenesis for this increased mortality is poorly understood. In the present study, we aimed to investigate the relationship between mediastinitis and persistently elevated cardiac-specific biomarkers [troponin T (TnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP)] and C-reactive protein (CRP) at mid-term follow-up following CABG. Material and methods The epidemiologic design was of an exposed (mediastinitis, n = 41) vs. randomly selected non-exposed (non-mediastinitis) controls (n = 41) cohort. Serum samples for measurements of NT-proBNP, TnT, and CRP were obtained at a median follow up time of 2.7 (range 0.5-5.2) years after CABG surgery. Results NT-proBNP (mean 65.0 pg/ml vs. 34.8 pg/ml, p = 0.007) and TnT levels (mean 14.7 ng/L vs. 11.2 ng/L, p = 0.004) were significantly higher in the mediastinitis group than in the control group. Patients with mediastinitis had also higher body mass index (BMI) and were more likely to have diabetes and previous myocardial infarction. There was no difference in serum CRP level between the groups. After controlling for potential confounders (previous myocardial infarction, age, and BMI), the presence of mediastinitis was associated with higher levels of log NT-proBNP (p = 0.02) and log TnT (p = 0.04). Conclusion Mediastinitis increases the concentrations of cardiac-specific biomarkers NT-proBNP and TnT at mid-term follow-up, representing persistent myocardial injury and impaired cardiac function.

BEtablocker Treatment After acute Myocardial Infarction in revascularized patients without reduced left ventricular ejection fraction (BETAMI): Rationale and design of a prospective, randomized, open, blinded end point study. Am Heart J 2019; 208:37-46. [PMID: 30530121 DOI: 10.1016/j.ahj.2018.10.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Accepted: 10/20/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND Current guidelines on the use of β-blockers in post-acute myocardial infarction (MI) patients without reduced left ventricular ejection fraction (LVEF) are based on studies before the implementation of modern reperfusion and secondary prevention therapies. It remains unknown whether β-blockers will reduce mortality and recurrent MI in contemporary revascularized post-MI patients without reduced LVEF. DESIGN BETAMI is a prospective, randomized, open, blinded end point multicenter study in 10,000 MI patients designed to test the superiority of oral β-blocker therapy compared to no β-blocker therapy. Patients with LVEF ≥40% following treatment with percutaneous coronary intervention or thrombolysis and/or no clinical signs of heart failure are eligible to participate. The primary end point is a composite of all-cause mortality or recurrent MI obtained from national registries over a mean follow-up period of 3 years. Safety end points include rates of nonfatal MI, all-cause mortality, ventricular arrhythmias, and hospitalizations for heart failure obtained from hospital medical records 30 days after randomization, and from national registries after 6 and 18 months. Key secondary end points include recurrent MI, heart failure, cardiovascular and all-cause mortality, and clinical outcomes linked to β-blocker therapy including drug adherence, adverse effects, cardiovascular risk factors, psychosocial factors, and health economy. Statistical analyses will be conducted according to the intention-to-treat principle. A prespecified per-protocol analysis (patients truly on β-blockers or not) will also be conducted. CONCLUSIONS The results from the BETAMI trial may have the potential of changing current clinical practice for treatment with β-blockers following MI in patients without reduced LVEF. EudraCT number 2018-000590-75.

Abstract
OBJECTIVES To evaluate long-term and time trends of survival in patients with a clinical diagnosis of type 1 and type 2 diabetes compared to patients without diabetes in a population referred for invasive treatment of coronary disease. METHODS Patients examined for heart disease at the Feiring LHL Clinics from March 1999 until December 2014 were followed for survival until 20 September, 2015. This yielded 43,872 patients with a known survival status including 1,326 (3.0%) patients with type 1 diabetes and 4,564 (10.9%) with type 2 diabetes. RESULTS Cox regression revealed a hazard ratio (HR) in type 1 and type 2 diabetes, respectively, of 1.78 (95% confidence interval [CI] 1.60-1.99) and 1.29 (95% CI 1.21-1.37). Comparing survival in the treatment periods before and after 2007, patients without diabetes and with type 2 diabetes had a reduced HR of 0.78 (95% CI 0.72-0.84) and 0.76 (95% CI 0.63-0.91), respectively, but there was no reduction in type 1 diabetes (HR 1.03; 95% CI 0.74-1.42). CONCLUSIONS Type 1 and type 2 diabetes have excess long-term mortality. In the nondiabetic and type 2 diabetic patients, a reduction in mortality has been noted in recent years, but has not been observed in type 1 diabetic patients.

Abstract
Objectives To assess whether there exists a long-term difference in survival after treatment with coronary bypass surgery or percutaneous coronary intervention in patients with coronary disease as judged by all-cause mortality. Methods Retrospective study from the Feiring Heart Clinic database of survival in 22 880 patients—15 078 treated with percutaneous coronary intervention and 7802 with bypass surgery followed up to 16 years. Results Cox regression and propensity score analysis showed no difference in survival for one-vessel and two-vessel disease during the whole study period. In three-vessel disease, however, the analysis revealed a consistent and highly significant survival benefit in the first 8 years with an HR of 0.76 (95% CI 0.69 to 0.84, p<0.001) in favour of bypass surgery with similar survival rates in the two treatment strategies after that time period. Conclusions Treatment strategy did not affect survival in one-vessel and two-vessel disease, but bypass surgery offered an improved survival in the first 8 years in patients with three-vessel disease. These results are consistent with most previous reports and the survival benefit should be taken into account when selecting a strategy for this patient group.

Abstract
Disclosure of potential conflicts of interest is used by biomedical journals to guarantee credibility and transparency of the scientific process. Conflict of interest disclosure, however, is not systematically nor consistently dealt with by journals. Recent joint editorial efforts paved the way towards the implementation of uniform vehicles for conflicts of interest disclosure. This paper provides a comprehensive editorial perspective on classical conflict of interest-related issues. New insights into current conflicts of interest policies and practices among European Society of Cardiology national cardiovascular journals, as derived from a cross-sectional survey using a standardized questionnaire, are discussed.

Abstract
OBJECTIVES To evaluate the usefulness of coronary angiography by 16-detector multislice spiral computed tomography (MSCT) in community hospital outpatients. DESIGN MSCT was performed at the community hospital in 157 of 218 consecutive outpatients with suspected significant coronary disease, before referral for invasive coronary angiography. RESULTS 101 patients had interpretable MSCT angiograms (64 men, age 62+/-10 years, calcium score 373+/-678, heart rate 56+/-7 beats/min, beta-blocker used by 91%). Coronary stenoses >50% were identified by invasive angiography in 49 patients. Only 79% of all segments could be assessed by MSCT due to heavy coronary calcification (12%) and blurred images (9%) in the remaining. By interpreting non-assessable segments as negative results 79 patients were correctly classified by MSCT. Sensitivity, specificity, positive and negative predictive values at patient level was 82%, 75%, 75% and 81%. By interpreting non-assessable segments as positive findings, the corresponding values were 100%, 29%, 57% and 100%, with correct diagnoses in 63% of patients. CONCLUSIONS Limited diagnostic accuracy, non-interpretable scans and radiation exposure restrict the usefulness of coronary MSCT in a community hospital setting.

Abstract
BACKGROUND Recent advances in computed tomography (CT) has made noninvasive imaging of the coronary arteries possible. Multidetector-CT (MDCT)-scanners capable of visualizing the coronary arteries will be available in most Norwegian hospitals within a few years. If the examinations have acceptable quality, diagnostics of coronary pathology could to some extent be decentralized. MATERIAL AND METHODS Our overview is based on non-systematic review of relevant literature, as well as our own experience. RESULTS AND DISCUSSION Good results have been shown for 16 and especially for 64 detector scanners in several comparative studies with invasive coronary angiography. The predictive value of a negative test is impressive in all the published studies. Significant coronary pathology is unlikely with a normal MDCT investigation of good quality, but MDCT's imprecise assessment of stenoses generates too many false positive findings. CT-technology is evolving rapidly. Yet, variable image quality and a high radiation dose are still challenging, even with modern CT-scanners. INTERPRETATION We advocate against uncritical use of the method, however, there is reason for optimism regarding the method's future contribution to coronary diagnostics.

Abstract
BACKGROUND Invasive coronary angiography is the gold standard for diagnosing coronary artery disease. CT angiography (CTA) is a non-invasive alternative that is more available and less expensive. Previous Norwegian experience with 16-channel CT has been less successful than that reported from other countries. Improved image resolution has increased expectations of a better diagnostic accuracy, but a new local assessment of the method's usefulness is needed before routine usage is implemented. MATERIAL AND METHODS Patients with suspected stabile coronary disease, referred to invasive coronary angiography, were first assessed with 64-channel CT angiography. Patients with atrial fibrillation or previous bypass operation were not included. All patients who fulfilled the eligibility criteria were included in the study (104), but 13 who had an Agatston calcium score > or = 800 and three for whom the examinations were technically unsuccessful were excluded; the study material therefore consisted of 88 patients. We assessed the method's ability (diagnostic accuracy) to detect diameter stenoses > or = 50% in coronary segments > or = 2 mm (without stent). RESULTS When 4% non-interpretable segments were interpreted as positive (stenotic), the sensitivity was 97%, the specificity 78% and the positive and negative predictive values were 77 and 98% on a patient level. For 50 patients who did not have significant stenosis, CTA correctly identified 39, but overestimated the degree of stenosis in 11 patients. INTERPRETATION 64-channel CTA is best at ruling out obstructive coronary artery disease in patients with intermediate risk of such disease. Few patients with significant lesions were missed due to false negative CTA evaluations, but false positive findings are a problem in low risk populations.
