Comparison of selective ET(A) and ET(B) receptor antagonists in patients with chronic heart failure

BACKGROUND: The vasoconstrictor action of endothelin-1 (ET-1) is mediated through ET(A) and ET(B) receptor subtypes on vascular smooth muscle. ET(B) receptors are also present on the vascular endothelium where they mediate vasodilation. Animal studies suggest that the ET(B) receptor also acts as a clearance receptor for endothelin. AIMS: To investigate the effects of a selective ET(A) and a selective ET(B) receptor antagonist alone and in combination on haemodynamics and circulating concentrations of ET-1 in patients with chronic heart failure. RESULTS: Infusion of BQ-123 (n=10), a selective ET(A) receptor antagonist, led to systemic vasodilation and did not change plasma ET-1 concentrations (1.38+/-0.82 to 1.38+/-0.91 fmol/ml, ns). Infusion of BQ-788 (n=8) led to systemic vasoconstriction with a rise in plasma ET-1 (1.84+/-1.06 to 2.73+/-0.99 fmol/ml, p<0.01). The addition of BQ-123 to BQ-788 led to systemic and pulmonary vasodilation with no further increase in plasma ET-1 concentrations (2.80+/-1.14 to 2.90+/-1.20 fmol/ml, ns). CONCLUSION: The rise in plasma ET-1 concentrations in response to selective blockade of ET(B) receptors and the associated adverse haemodynamic effects suggest that ET(B) receptors have a role in the clearance of ET-1 in man and that their blockade may not be advantageous for patients with heart failure.

Association Between Hemodynamic Profile,Physical Capacity and Quality of Life in Pulmonary Hypertension

Background

No studies have described and evaluated the association between hemodynamics, physical limitations and quality of life in patients with pulmonary hypertension (PH) without concomitant cardiovascular or respiratory disease.

Objective

To describe the hemodynamic profile, quality of life and physical capacity of patients with PH from groups I and IV and to study the association between these outcomes.

Methods

Cross-sectional study of patients with PH from clinical groups I and IV and functional classes II and III undergoing the following assessments: hemodynamics, exercise tolerance and quality of life.

Results

This study assessed 20 patients with a mean age of 46.8 ± 14.3 years. They had pulmonary capillary wedge pressure of 10.5 ± 3.7 mm Hg, 6-minute walk distance test (6MWDT) of 463 ± 78 m, oxygen consumption at peak exercise of 12.9 ± 4.3 mLO2.kg-1.min-1 and scores of quality of life domains < 60%. There were associations between cardiac index (CI) and ventilatory equivalent for CO2 (r=-0.59, p <0.01), IC and ventilatory equivalent for oxygen (r=-0.49, p<0.05), right atrial pressure (RAP) and ''general health perception'' domain (r=-0.61, p<0.01), RAP and 6MWTD (r=-0.49, p<0.05), pulmonary vascular resistance (PVR) and ''physical functioning'' domain (r=-0.56, p<0.01), PVR and 6MWTD (r=-0.49, p<0.05) and PVR index and physical capacity (r=-0.51, p<0.01).

Conclusion

Patients with PH from groups I and IV and functional classes II and III exhibit a reduction in physical capacity and in the physical and mental components of quality of life. The hemodynamic variables CI, diastolic pulmonary arterial pressure, RAP, PVR and PVR index are associated with exercise tolerance and quality of life domains.     

The value of B-type natriuretic peptide and big endothelin-1 for detection of severe pulmonary hypertension in heart transplant candidates

BACKGROUND: Severe pulmonary hypertension (PH) and increased pulmonary vascular resistance (PVR) are important risk factors that predict early postoperative mortality after orthotopic heart transplantation. The aim of our study was to determine the value of B-type natriuretic peptide (BNP) and big endothelin-1 (big ET1) for prediction of severe PH in heart transplant candidates. METHODS: The study population included 43 potential heart transplant candidates (38 males, mean age 52 +/- 7 years). All underwent repeated right-heart catheterizations (2-5 studies) at an interval of 3-4 months, giving a total of 124 examinations, associated with blood sampling for BNP and big ET1 analysis. Severe PH was defined as the mean pulmonary artery pressure (MPAP) > 40 mmHg. RESULTS: Significantly high PVR (PVR > 3.0 Wood units and TPG > 15 mmHg) was noted on 12 occasions in 10 patients; always in the presence of severe PH. Low BNP levels (<67 pg/ml) ruled out the presence of severe PH with a 100% sensitivity, however, with a low specificity (34%). An increase in plasma BNP > 30 pg/ml (>40% of initial value) in subjects with a previous MPAP< or =40 mmHg detected development of severe PH with a 100% sensitivity and an 80-88% specificity. As a total of 58% of patients presented repeatedly with MPAP< or =40 mmHg, serial BNP testing could reduce the need for hemodynamic studies in this subgroup down to 12-20%. CONCLUSIONS: Serial BNP testing in hemodynamically stable heart transplant candidates with MPAP< or =40 mmHg allows reliable detection of development of severe PH, and may significantly reduce the need for repeated right-heart catheterizations in these patients.     

CHD合并PH患者血浆ET-1浓度与肺血管C-MYC癌基因表达的关系

目的探讨内皮素(ET-1)、C-MYC癌基因在先天性心脏病(CHD)合并肺动脉高压(PH)形成过程中的生物作用。方法42例左向右分流CHD患者,根据肺动脉平均压(MPAP)的高低分为三组,正常组:MPAP<20mmHg,11例;肺动脉高压组:MPAP>20mmHg,22例;重度肺动脉高压组:MPAP>70mmHg,9例。采用放免法测定血浆ET-1浓度。所有病例均行肺活检术,标本常规制成蜡块,应用免疫组化方法,单克隆抗C-MYC基因蛋白抗体作一抗,观察肺组织中C-MYC癌基因的定位及表达。结果C-MYC癌基因主要分布于肺动脉内皮细胞、平滑肌和成纤维细胞等细胞的胞核中。血浆ET-1浓度和C-MYC癌基因表达各组之间差异有统计学意义(P<0.05),各病理分级之间差异有统计学意义(P<0.05),随着肺小动脉病理分级的加重而升高,并且二者的表达与病理分级有明显的相关性(P<0.05)。结论ET-1和C-MYC癌基因在CHD合并PH的形成过程中起着重要的生物学作用,ET-1可以刺激C-MYC癌基因的表达,进而促进平滑肌细胞和成纤维细胞增殖。     

Pulmonary hypertension in systemic lupus erythematosus

A prospective echocardiographic and clinical study was performed on 84 Chinese patients with systemic lupus erythematosus (SLE) and 99 controls to investigate the prevalence and the mechanism of pulmonary hypertension (PH) in SLE. Comparison between Doppler estimation and catheterization measurement was made in 12 cases to validate the predictive method. Compared to normal subjects, lupus patients had significantly increased sys-tolic pulmonary artery pressure (SPAP) (29.59±12.52 vs 19.64±5.82, P<0.001), mean pulmonary artery pressure (MPAP) (15.11±7.36 vs 10.21±4.72, P<0.001) and total pulmonary resistance (TPR) (315.85±190.65 vs 220.37± 55.92, P<0.001). Nine of the 84 patients presented PH, defined as SPAP >30 mmHg and MPAP >20 mmHg. Pulmonary hypertensive patients had higher serum endothelin (ET) than non-pulmonary hypertensive patients, were more commonly in active stages, and presented Raynaud's phenomenon and rheumatoid factors. ET level was correlated with echocardiographic pulmonary pressure. Pulmonary hypertension commonly occurs in Chinese patients with SLE (11%), and it correlates with the lupus activity and the elevation of serum endothelin.

Right and left ventricular function and pulmonary artery pressure in patients with bronchiectasis

BACKGROUND: Bronchiectasis may have deleterious effects on cardiac function secondary to pulmonary hypertension (PH). This study was designed to assess cardiac function and determine the prevalence of PH in patients with cystic and cylindrical bronchiectasis. METHODS: A cross-sectional study of patients with bronchiectasis diagnosed by CT scan was conducted at King Khalid University Hospital, Riyadh, Saudi Arabia between December 2005 and January 2007. Pulmonary function tests were performed, arterial blood gas measurements were made, and cardiac function and systolic pulmonary artery pressure (SPAP) were assessed by echocardiography. RESULTS: Of 94 patients (31% men, n = 29), 62 patients (66%) had cystic bronchiectasis and 32 patients (34%) had cylindrical bronchiectasis. Right ventricular (RV) systolic dysfunction was observed in 12 patients (12.8%), left ventricular (LV) systolic dysfunction was observed in 3 patients (3.3%), and LV diastolic dysfunction was observed in 11 patients (11.7%); all had cystic bronchiectasis. RV dimensions were significantly greater in the cystic bronchiectasis group, and were positively correlated with SPAP (p < 0.0001) and negatively correlated with Pao2 (p < 0.016). Other hemodynamic variables were not different between groups. PH in 31 patients (32.9%) was significantly greater in patients with cystic bronchiectasis compared with cylindrical bronchiectasis (p = 0.04). In cystic bronchiectasis, SPAP was positively correlated with Paco2 (p = 0.001), and inversely correlated with Pao2 (p = 0.03), diffusion capacity of the lung for carbon monoxide percentage (p = 0.02), and FEV1 (p = 0.02). CONCLUSIONS: RV systolic dysfunction and PH were more common than LV systolic dysfunction in bronchiectatic patients. LV diastolic dysfunction was mainly seen in severe PH. We recommend detailed assessment of cardiac function, particularly LV diastolic function, in patients with bronchiectasis.
