Systemic amyloidoses are rare and proteiform diseases, caused by extracellular accumulation of insoluble misfolded fibrillar proteins. Prognosis is dictated by cardiac involvement, which is especially frequent in light chain (AL) and in transthyretin variants (ATTR, both mutated, (ATTRm), and wild-type, (ATTRwt)). Recently, ATTRwt has emerged as a potentially relevant cause of a heart failure with preserved ejection fraction (HFpEF). Cardiac amyloidosis is an archetypal example of restrictive cardiomyopathy, with signs and symptoms of global heart failure and diastolic dysfunction...

BACKGROUND: The use of plasma biomarkers is relevant for the prognosis of ST-segment elevation myocardial infarction (STEMI) patients. Apelin, an adipocytokine, plays a pivotal role in the pathophysiology of both ischemia/reperfusion injury and its potential subsequent heart failure. We evaluated apelin concentrations at admission as a biomarker to assess risk of 6-month mortality. METHODS: Consecutive patients with STEMI were recruited from January 2012 to January 2013 (n=250)...

BACKGROUND: Once aortic stenosis (AS) is severe, patients develop symptoms at different stages. Indeed, symptom status may correlate poorly with the grade of valve narrowing. Multiple pathophysiological mechanisms, other than valvular load, may explain the link between AS and symptom severity. We aimed to describe the relationship between the severity of symptoms and the characteristics of a cohort of patients with severe AS already referred for aortic valve replacement (AVR). METHODS: We analyzed 118 consecutive patients (70±9 years, 55% men) with severe AS referred for AVR...

Heart failure, a leading cause of death in humans, can emanate from myocarditis. Although most individuals with myocarditis recover spontaneously, some develop chronic dilated cardiomyopathy. Myocarditis may result from both infectious and noninfectious causes, including autoimmune responses to cardiac antigens. In support of this notion, intracellular cardiac antigens, like cardiac myosin heavy chain-α, cardiac troponin-I, and adenine nucleotide translocator 1 (ANT1), have been identified as autoantigens in cardiac autoimmunity...

L-type Ca(2+) currents conducted by voltage-gated calcium channel 1.2 (CaV1.2) initiate excitation-contraction coupling in the heart, and altered expression of CaV1.2 causes heart failure in mice. Here we show unexpectedly that reducing β-adrenergic regulation of CaV1.2 channels by mutation of a single PKA site, Ser1700, in the proximal C-terminal domain causes reduced contractile function, cardiac hypertrophy, and heart failure without changes in expression, localization, or function of the CaV1.2 protein in the mutant mice (SA mice)...

Right ventricular (RV) failure is the major cause of death among patients with pulmonary hypertension. However, differences between the RV and left ventricle (LV) of the adult heart have not been defined, despite myocytes from these two ventricles originate from different progenitor cells. The lack of such knowledge interferes with developing therapeutic strategies to protect the RV. The goal of this study was to identify possible differences between stress responses in the RV and LV free walls of adult rats...

BACKGROUND: -The number of patients with adult congenital heart disease (ACHD) is rapidly increasing. In order to optimize patient management, there is a great need to accurately identify high-risk patients. Still, no biomarker has been firmly established as a clinically useful prognostic tool in this group. We studied the association of N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitive troponin-T (hs-TnT) and growth-differentiation factor 15 (GDF-15) with cardiovascular events in ACHD...

In cardiac and skeletal muscle, the troponin complex turns muscle contraction on and off in a calcium-dependent manner. Many small molecules are known to bind to the troponin complex to modulate its calcium binding affinity, and this may be useful in a broad range of conditions in which striated muscle function is compromised, such as congestive heart failure. As a tool for developing drugs specific for the cardiac isoform of troponin, we have designed a chimeric construct (cChimera) consisting of the regulatory N-terminal domain of cardiac troponin C (cNTnC) fused to the switch region of cardiac troponin I (cTnI), mimicking the key binding event that turns on muscle contraction...

BACKGROUND: -Both tobacco smoking and circulating cardiac troponin I (cTnI) levels are associated with the risk of acute myocardial infarction (AMI), heart failure (HF) and cardiovascular death. However, whether cardiac troponin I levels differ according to smoking status, or whether smoking modifies the prognostic relationship between cardiac troponin I and outcomes remain unclear. METHODS: -Using data from a large population-based cohort, we assessed the association between smoking and cTnI, and the impact of smoking on the associations between cTnI levels and the incidence of AMI, HF and cardiovascular death...

REVIEW
Torbjørn Omland, Harvey D White
BACKGROUND: Multiple circulating biomarkers have been associated with the incidence of cardiovascular events and proposed as potential tools for risk stratification in stable ischemic heart disease (IHD), yet current guidelines do not make any firm recommendations concerning the use of biomarkers for risk stratification in this setting. This state-of-the-art review provides an overview of biomarkers for risk stratification in stable IHD. CONTENT: Circulating biomarkers associated with the risk of cardiovascular events in patients with stable IHD reflect different pathophysiological processes, including myocardial injury, myocardial stress and remodeling, metabolic status, vascular inflammation, and oxidative stress...

The circulating concentration of cardiac troponin I (cTnI) is an index of subclinical myocardial injury in several patient populations and in the general population. Erectile dysfunction is associated with greater risk for cardiovascular events, but the association with subclinical myocardial injury is not known. We aimed to test the hypothesis that the presence and severity of erectile dysfunction is associated with greater concentrations of cTnI in the general population. The presence and severity of erectile dysfunction was assessed by administering the International Index of Erectile Function 5 (IIEF-5) questionnaire to 260 men aged 30 to 65 years recruited from a population-based study...

OBJECTIVE: To identify patients with type 2 myocardial infarction (MI) and patients with non-ischaemic myocardial injury (NIMI) and to compare their prognosis with those of patients with type 1 MI. METHODS: A retrospective observational study was performed in 1010 patients admitted to the emergency department of a university hospital with at least one troponin I test between 2012 and 2013. Participants were identified using laboratory records and divided into three groups: type 1 MI (rupture of atheromatous plaque), type 2 MI (imbalance between myocardial oxygen supply and/or demand) and NIMI (patients who did not meet diagnostic criteria for type 1 or type 2 MI)...

Ghrelin exhibits a cardioprotective effect. We examined whether orally administered ghrelin-containing salmon stomach extract (sSE) instead of chemically synthesized ghrelin protects against doxorubicin (DOX)-induced cardiotoxicity in mice. Mice were divided into four groups: (i) the control, (ii) DOX groups were fed a control diet (AIN-93G), (iii) the sSE, and (iv) DOX + sSE groups were fed a 10% sSE diet (AIN-93G + 10% sSE). After a 4-week pretreatment of sSE, DOX or saline was administered to the corresponding groups by intraperitoneal injection...

Little is known regarding objective predictors of cachexia affecting patients with heart failure (HF). We studied 108 stable chronic systolic HF patients with serial echocardiography and biomarker measurements over 10 months. Cachexia was defined as weight loss ≥5 % from baseline or final BMI <20 kg/m(2); 18.5 % developed cachexia. While there were no significant differences in baseline or serial echocardiographic measures in those developing cachexia, we found significant differences in baseline amino-terminal pro-B type natriuretic peptide (NT-proBNP), highly sensitive troponin I, sST2, and endothelin-1...

INTRODUCTION: Stroke is one of the leading causes of morbidity and mortality. Cardiac troponins have been found to be increased in other conditions apart from the cardiac diseases, such as stroke. The aim of the study was to assess the correlation between elevated troponin I levels and stroke outcome. METHODS: This retrospective study included 198 acute ischemic stroke patients in whom troponin I levels have been obtained at admission. Exclusion criteria were concomitant acute coronary syndrome, congestive heart failure, pulmonary embolism, renal failure, rhabdomyolysis and septic conditions...

Restrictive cardiomyopathy is a rare form of pediatric cardiac disease, for which the known genes include MYH7, TNNT2, TNNI3, ACTC1, and DES. We describe a pediatric proband with fatal restrictive cardiomyopathy associated with septal hypertrophy and compound heterozygosity for TNNC1 mutations (NM_003280: p.A8V [c.C23T] and p.D145E [c.C435A]). This association between restrictive cardiomyopathy and TNNC1 mutations was strengthened by prospective observations on the second pregnancy in the family which revealed, in the presence of the same TNNC1 genotype, prenatally diagnosed hypertrophic cardiomyopathy which evolved into restrictive cardiomyopathy, heart failure and death at the age of 9 months...
