Natriuretic peptides to differentiate constrictive pericarditis and restrictive cardiomyopathy: A systematic review and meta-analysis.
    Clinical cardiology, 2022, Volume: 45, Issue:3

    Previous studies have shown that natriuretic peptide levels are increased in patients with restrictive cardiomyopathy (RCM) but not in constrictive pericarditis (CP). We performed a systematic review and meta-analysis to evaluate the diagnostic utility of B-type natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) to differentiate CP and RCM. We searched electronic databases from inception to January 07, 2021. Studies involving adult patients that assessed the utility of natriuretic peptides to differentiate CP and RCM were included. All meta-analyses were performed using a random-effects model. Seven studies (four case-control and three cohorts) involving 204 patients were included. The mean age ranged between 25.7 and 64.1 years and 77% of patients were men. BNP levels were significantly lower (standardized median difference [SMD], -1.48; 95% confidence interval [CI], -2.33 to -0.63) in patients with CP compared to RCM. The pooled area under the curve (AUC) of the BNP level was 0.81 (95% CI, 0.70-0.92). NT-proBNP (SMD, -0.86; 95% CI, -1.38 to -0.33) and log NT-proBNP (SMD, -1.89; 95% CI, -2.59 to -1.20) levels were significantly lower in patients with CP compared to RCM. Our review shows that BNP and NT-proBNP levels were significantly lower in patients with CP compared to RCM. The pooled AUC of BNP level showed a good diagnostic accuracy to differentiate both conditions.

Primary and Secondary Diastolic Dysfunction in Heart Failure With Preserved Ejection Fraction.
    The American journal of cardiology, 2018, 11-01, Volume: 122, Issue:9

    Approximately 50% of patients with symptoms and signs of heart failure have a left ventricular ejection fraction (LVEF) ≥50% and are often simply referred to as 'heart failure with preserved EF', 'HFpEF'. Many of such patients have HF secondary to specific cardiac conditions (i.e., valvular or pericardial disease) in which the symptoms and signs occur despite the LVEF being preserved due to diastolic dysfunction secondary to the underlying disease (secondary HFpEF), differently from those HFpEF patients in which the impaired LV filling is due to a primary diastolic dysfunction (primary HFpEF). When primary HFpEF patients are properly diagnosed, they appear to have a milder form of HF with a lower cardiovascular mortality compared with HFrEF and secondary HFpEF population, but a risk of HF hospitalization that is significantly higher than patients with similar cardiovascular risk factors but without the diagnosis of HFpEF. We herein review the diagnostic approach to HFpEF and present a differential diagnosis of HFpEF in a primary and secondary form.

The amyloidogenic V122I transthyretin variant in elderly black Americans.
    The New England journal of medicine, 2015, Jan-01, Volume: 372, Issue:1

    Approximately 4% of black Americans carry a valine-to-isoleucine substitution (V122I) in the transthyretin protein, which has been associated with late-onset restrictive amyloid cardiomyopathy and increased risks of death and heart failure.. We determined genotype status for the transthyretin gene (TTR) in 3856 black participants in the Atherosclerosis Risk in Communities study and assessed clinical profiles, mortality, and the risk of incident heart failure in V122I TTR variant carriers (124 participants [3%]) versus noncarriers (3732 participants). Cardiac structure and function and features suggestive of cardiac amyloidosis were assessed in participants who underwent echocardiography during visit 5 (2011 to 2013), when they were older than 65 years of age.. After 21.5 years of follow-up, we did not detect a significant difference in mortality between carriers (41 deaths, 33%) and noncarriers (1382 deaths, 37%; age- and sex-stratified hazard ratio among carriers, 0.99; 95% confidence interval [CI], 0.73 to 1.36; P=0.97). The TTR variant was associated with an increased risk of incident heart failure (age- and sex-stratified hazard ratio, 1.47; 95% CI, 1.03 to 2.10; P=0.04). On echocardiography at visit 5, carriers (46 participants) had worse systolic and diastolic function, as well as a higher level of N-terminal pro-brain natriuretic peptide, than noncarriers (1194 participants), although carriers had a low prevalence (7%) of overt manifestations of amyloid cardiomyopathy.. We did not detect a significant difference in mortality between V122I TTR allele carriers and noncarriers, a finding that contrasts with prior observations; however, the risk of heart failure was increased among carriers. The prevalence of overt cardiac abnormalities among V122I TTR carriers was low. (Funded by the National Heart, Lung, and Blood Institute and others.).

Two cases of restrictive cardiomyopathy in children.
    Journal of Nippon Medical School = Nippon Ika Daigaku zasshi, 2009, Volume: 76, Issue:6

    A 3-year-old girl was diagnosed with restrictive cardiomyopathy (RCM) after showing symptoms of heart failure, and a 6-year-old boy was found to have RCM after abnormal electrocardiographic findings were seen during school-based heart disease screening. Both had typical clinical features of the disease. Plasma levels of brain natriuretic peptide increased significantly in both patients, allowing us to distinguish this disease from constrictive pericarditis which has similar clinical and hemodynamic features. The early diastolic mitral annular velocity recorded by tissue Doppler echocardiography was also useful to discriminate RCM from constrictive pericarditis. The former case successfully received heart transplantation, but the latter case died suddenly prior to receiving a heart transplant. The plasma level of brain natriuretic peptide and tissue Doppler echocardiography helped us to diagnose this disease earlier and follow it more carefully, which has important implications in optimal treatment and improved prognosis of RCM in children.

Comparison of usefulness of tissue Doppler imaging versus brain natriuretic peptide for differentiation of constrictive pericardial disease from restrictive cardiomyopathy.
    The American journal of cardiology, 2008, Aug-01, Volume: 102, Issue:3

    Brain (B-type) natriuretic peptide (BNP) and tissue Doppler imaging may distinguish restrictive cardiomyopathy (RCMP) from idiopathic constrictive pericardial disease (CP). However, their comparative efficacy is unknown for patients with CP from secondary causes (e.g., surgery or radiotherapy). We compared the efficacy of tissue Doppler imaging and BNP for differentiation of RCMP (n = 15) and CP (n = 16) were compared. BNP was higher in patients with RCMP than CP (p = 0.008), but the groups overlapped, particularly for BNP <400 pg/ml. BNP was lower with idiopathic CP than secondary CP (139 +/- 50 vs 293 +/- 69 pg/ml; p <0.001) or RCMP (139 +/- 50 vs 595 +/- 499 pg/ml; p <0.001), but not significantly different between those with secondary CP and RCMP (293 +/- 69 vs 595 +/- 499 pg/ml; p = 0.1). Patients with CP and RCMP had less overlap in early diastolic and isovolumic contraction tissue Doppler imaging velocities compared with BNP, with clear separation of groups evident with mean early diastolic annular velocities (averaged from 4 walls). Early diastolic tissue Doppler imaging velocity was superior to BNP for differentiation of CP and RCMP (area under the curve 0.97 vs 0.76, respectively; p = 0.01). In conclusion, mean early diastolic mitral annular velocity correctly distinguished CP from RCMP even when there was a large overlap of BNP between the 2 groups.

Serum NT pro-BNP: relation to systolic and diastolic function in cardiomyopathies and pericardiopathies.
    Arquivos brasileiros de cardiologia, 2008, Volume: 91, Issue:1

    NT pro-BNP is a marker of systolic and diastolic dysfunction.. To determine NT pro-BNP levels in patients with chagasic, hypertrophic, and restrictive heart diseases, as well as with pericardial diseases, and their relation to echocardiographic measurements of systolic and diastolic dysfunction.. A total of 145 patients were divided into the following groups: 1) Chagas' heart disease (CHD)--14 patients; 2) hypertrophic cardiomyopathy (HCM)--71 patients; 3) endomyocardial fibrosis (EMF)--26 patients; 4) pericardial effusion (PE)--18 patients; and 5) constrictive pericarditis (CP)--16 patients. The control group was comprised of 40 individuals with no heart disease. The degree of myocardial impairment and pericardial effusion were assessed by two-dimensional echocardiography and the degree of restriction by pulsed Doppler transmitral flow. The diagnosis of CP was confirmed through magnetic resonance imaging. NT pro-BNP levels were determined through electrochemiluminescence immunoassay.. NT pro-BNP was increased (p < 0.001) in CHD (median = 513.8 pg/ml), HCM (median = 848 pg/ml), EMF (median = 633 pg/ml), CP (median = 568 pg/ml), and PE (median = 124 pg/ml), when compared with the control group (median = 28 pg/ml). No statistically significant differences were found between CP and EMF (p = 0.14). In the hypertrophic group, NT pro-BNP was correlated with left atrial size (r = 0.40; p < 0.001) and with E/Ea ratio (p < 0.01). In the restrictive group, there was a trend of correlation with E-wave peak velocity (r = 0.439; p = 0.06).. NT pro-BNP is increased in the different cardiomyopathies and pericardial diseases and is correlated with the degree of systolic and diastolic dysfunction.

Utility of BNP in differentiating constrictive pericarditis from restrictive cardiomyopathy in patients with renal insufficiency.
    Journal of cardiac failure, 2007, Volume: 13, Issue:8

    Differentiating between constrictive pericarditis (CP) and restrictive cardiomyopathy (RCMP) is difficult because of similar clinical and hemodynamic presentation. Brain natriuretic peptide (BNP) has been reported a useful noninvasive biomarker to differentiate CP from RCMP; however, its utility in patients with renal insufficiency has not been evaluated.. Consecutive patients with suspected CP or RCMP were enrolled. All but 7 patients underwent transseptal catheterization. BNP, renal function, and comorbid conditions were recorded at the time of the procedure. Renal function was estimated using the Cockcroft-Gault formula. Descriptive statistics, Student t-test, and Mann-Whitney U test were performed; P < .05 was significant. Twenty-two patients had hemodynamically or surgically proven CP or RC. In patients with CP, 9 had at least Stage II kidney disease (GFR <90 mL/min, mean 58) and 8 had normal or Stage I kidney disease (GFR >90 mL/min, mean 118). BNP was higher in patients with CP and renal insufficiency versus those with CP and normal renal function (433 versus 116 pg/mL; P = .016). BNP in patients with CP and normal renal function was lower than in patients with RC (116 versus 728 pg/mL; P = .005).. BNP has reduced clinical utility in renal insufficiency to differentiate CP from RCMP.

B-type natriuretic peptide level in a patient with constrictive pericarditis.
    Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 2006, Volume: 68, Issue:6

    We report the case of a 35-year-old man with constrictive pericarditis who had a B-type natriuretic peptide (BNP) level of 129 pg/dl despite a left ventricular end diastolic pressure of 35 mmHg. We discuss a possible explanation for the relatively low BNP level given this patient's markedly elevated intracavitary pressures in the setting of constrictive pericarditis.

The efficacy of brain natriuretic peptide levels in differentiating constrictive pericarditis from restrictive cardiomyopathy.
    Journal of the American College of Cardiology, 2005, Jun-07, Volume: 45, Issue:11

    We sought to determine the usefulness of brain natriuretic peptide (BNP) measurements to differentiate constrictive pericarditis (CP) from restrictive cardiomyopathy (RCMP).. The differentiation of CP from RCMP may be clinically difficult and often requires hemodynamic assessment. No laboratory marker has been shown to differentiate the two conditions.. We measured BNP levels in 11 patients suspected of having either CP or RCMP. All patients had hemodynamic assessment the day of BNP measurements.. Six patients had CP and five patients had RCMP based on established hemodynamic criteria. Both CP and RCMP patients had similar elevation in intracardiac pressures. Despite similar pressures, the mean plasma BNP levels were significantly higher in RCMP compared to CP (825.8 +/- 172.2 pg/ml vs. 128.0 +/- 52.7 pg/ml, p < 0.001, respectively).. The BNP levels are significantly elevated in RCMP compared to CP patients; BNP may prove to be a useful noninvasive marker for the differentiation of the two conditions.
