The possible use of biochemical markers in the postmortem diagnosis of myocardial ischemia is well known in the forensic setting, though several issues have limited its widespread adoption. The study presented herein focuses of N-terminal pro-B-type natriuretic peptide, troponin T, and troponin I, and the possible influence due to sampling site chosen, postmortem interval elapsed, and cardiopulmonary resuscitation attempts. Comparisons were performed between antemortem serum levels of these markers and postmortem levels measured in pericardial fluid and postmortem serum samples obtained from different sampling sites (n=16)...

Sodium-glucose co-transporter 2 inhibitors (SGLT2is) such as dapagliflozin, canagliflozin, and empagliflozin, are a promising new therapy in the treatment of type 2 diabetes mellitus (T2DM). SGLT2is can effectively reduce hyperglycemia thus improving glycemic control and they offer some beneficial effects on the cardiovascular (CV) system which can benefit patients with heart failure in addition toT2DM. The United States Food and Drug Administration requires new diabetes mellitus therapies to show a CV safety profile...

Assessment of serum levels of natriuretic peptides, especially the amino-terminal portion (NT-proBNP) and the carboxy-terminal portion (BNP) of pro-B-type natriuretic peptide, has had a highly significant clinical impact on the diagnosis and prognostic stratification of patients with heart failure (HF). They are now an instrument with recognized value in this context and several studies have demonstrated their value in tailoring therapy for these patients. Following the recent advent of angiotensin receptor-neprilysin inhibitors (ARNIs), there is a need to review how these two biomarkers are interpreted in HF...

Results of acute pulmonary vasodilator testing (AVT) and the outcome of medical therapy have not been described in patients with segmental pulmonary vascular disease (SPVD). We sought to compare the pulmonary vasodilatory effects of oxygen, oxygen with nitric oxide, and diltiazem, and to describe the clinical course of patients with SPVD and pulmonary hypertension. A retrospective review of 16 patients with pulmonary hypertension and SPVD involving 2-3 major lung segments who underwent AVT between January 2000 and December 2015 was performed...

PURPOSE OF REVIEW: Calcific aortic valve stenosis is the most prevalent valvular heart disease in the high-income countries. To this date, no medical therapy has been proven to prevent or to stop the progression of aortic valve stenosis. The physiopathology of aortic valve stenosis is highly complex and involves several signalling pathways, as well as genetic related factors, which delay the elaboration of effective pharmacotherapies. Moreover, it is difficult to predict accurately the progression of the valve stenosis and finding the optimal timing for aortic valve replacement remains challenging...

Michy P Kelly
Deficits in brain function that are associated with aging and age-related diseases benefit very little from currently available therapies, suggesting a better understanding of the underlying molecular mechanisms is needed to develop improved drugs. Here, we review the literature to test the hypothesis that a break down in cyclic nucleotide signaling at the level of synthesis, execution, and/or degradation may contribute to these deficits. A number of findings have been reported in both the human and animal model literature that point to brain region-specific changes in Galphas (a...

Mitral regurgitation (MR) is a common cause of heart failure but may also remain silent without either symptoms or altered cardiac function. In the latter case, management is still controversial and biomarkers could be an important means to solving remaining issues in MR management. As objective markers of myocardial stress and early left ventricular dysfunction, biomarkers may for example facilitate the identification of patients with benefit from early surgery of degenerative MR. The most studied biomarkers are the natriuretic peptides (NPs), especially brain NP, as well as its N terminal prohormone...

BACKGROUND: The development of mitral stenosis (MS) is not uncommon after mitral valve (MV) repair for degenerative mitral regurgitation (MR), but the significance of MS in this setting has not been defined. METHODS: We prospectively studied 110 such patients who underwent supine bicycle exercise testing to assess intracardiac hemodynamics at rest and at peak exercise. B-type natriuretic peptide (BNP) levels were measured at rest and after the exercise test. The patients also performed the 6-minute walk test and completed the 36-Item Short Form Survey (SF-36)...

Biomarkers are quantitative indicators of biological processes performed by an organ or system. In recent years, natriuretic peptides (NPs) have emerged as important tools in the diagnosis and therapeutic monitoring of heart diseases. Research has shown that serum and plasma levels of N-terminal pro brain NP (NT-proBNP) in dogs and cats are the only biomarkers that afford to diagnose and monitor congestive processes and, indirectly, the myocardial function of small animals. The present review discusses the peer-reviewed specialized literature about NT-proBNP and presents and compares the potential clinical applications of this NP in veterinary medicine of small animals, considering diagnosis, follow-up, and prognosis of myocardial or systemic diseases...

Biomarkers are increasingly being investigated in the treatment of pulmonary vascular disease. In particular, the signaling pathways targeted by therapies for pulmonary arterial hypertension provide biomarkers that potentially can be used to guide therapy and to assess clinical response as an alternative to invasive procedures such as right-sided cardiac catheterization. Moreover, the growing use of combination therapy for both the initial and subsequent treatment of pulmonary arterial hypertension highlights the need for biomarkers in this treatment approach...

The nitric oxide-cyclic guanosine monophosphate (NO-cGMP) pathway plays a key role in regulating cardiovascular homeostasis, and genetic variants allocated to NO-cGMP pathway genes, leading to NO-cGMP deficiency, may influence the prevalence or course of cardiovascular disease. NO-cGMP deficiency can be caused by nitric oxide synthase substrate deficiency, substrate competition, defects, or uncoupling; endogenous inhibitors of nitric oxide synthase; decreased cGMP production; or increased cGMP degradation. This review presents evidence supporting the role of NO-cGMP deficiency in cardiovascular disease, including findings from genetic association studies for particular polymorphisms, haplotypes, and racial disparities...

Whether the increased atrial fibrillation (AF) risk in metabolic syndrome (MetS) patients is due to the syndrome as a whole or simply the sum of the risks of its individual component parts is still obscure. These two clinical entities share many pathophysiological links and thus distinction between a casual observation and a significant association is difficult. Biomarkers associated with pathogenesis of AF in the context of MetS have the ability to refine future risk prediction. In the present review we identify circulating substances that could be regarded as potential biomarkers for prediction of incident AF, or of cardiovascular events in the setting of AF in patients with MetS...

Cardiac natriuretic peptides have long been known to act as main players in the homeostatic control of blood pressure, salt and water balance. However, in the last few decades, new properties have been ascribed to these hormones. A systematic review of English articles using MEDLINE Search terms included prostate cancer, inflammation, cardiac hormones, atrial natriuretic peptide, and brain natriuretic peptide. Most recent publications were selected. Natriuretic peptides are strongly connected to the immune system, whose two branches, innate and adaptive, are finely tuned and organized to kill invaders and repair injured tissues...
