目的:探讨老年男性慢性心衰患者在经过标准化抗心衰治疗后的血浆脑利钠肽水平的分布及其影响因素.方法:选取我院高干病房心内科65例老年男性慢性心衰患者,收集患者一般资料、入院后检查结果及药物治疗情况,包括:年龄、有无心衰相关性疾病(高血压、糖尿病、冠心病、肾功能不全)、入院时心率、血压,入院后血肌酐、电解质、胸片有无肺淤血、超声心动图指标(ESV,EDV,EF)、出院前血浆BNP水平以及住院期间的药物治疗情况(主要指β-受体阻滞剂,ACEI或者ARB,强心剂、利尿剂等).住院期间给予标准化抗心衰治疗并在出院前检测血浆BNP水平,按BNP水平将患者分成高BNP组(BNP>463 pg/ml)和正常BNP组(BNP≤ 463 pg/ml),比较两组间各研究因素分布有无差异,并对BNP水平与各因素之间的相关性进行统计分析.结果:经过标准化抗心衰治疗,出院时高BNP组患者44例(67.69%),这部分患者更多的伴有血压低、心率快、高肺动脉压、肺淤血的胸片表现.同时还发现高BNP组的患者中房颤及冠心病的发病率也偏高.对BNP的影响因素进行多元线性回归分析后得出房颤、低收缩压、肺淤血、高肌酐为出院时高BNP水平的影响因素.结论:在不同BNP分组中多个研究因素的分布有显著统计学差异,提示老年男性慢性心衰患者伴有低血压、房颤、高肌酐、肺淤血是出院时高血浆BNP的危险因素,需要给予密切的医疗关注和治疗. 相似文献

Background
Cardioembolic stroke generally results in more severe disability, since it typically has a larger ischemic area than the other types of ischemic stroke. However, it is difficult to differentiate cardioembolic stroke from non-cardioembolic stroke (atherothrombotic stroke and lacunar stroke). In this study, we evaluated the levels of plasma brain natriuretic peptide in acute ischemic stroke patients with cardioembolic stroke or non-cardioembolic stroke, and assessed the prediction factors of plasma brain natriuretic peptide and whether we could differentiate between stroke subtypes on the basis of plasma brain natriuretic peptide concentrations in addition to patient's clinical variables.Methods
Our patient cohort consisted of 131 consecutive patients with acute cerebral infarction who were admitted to Kagawa University School of Medicine Hospital from January 1, 2005 to December 31, 2007. The mean age of patients (43 females, 88 males) was 69.6 ± 10.1 years. Sixty-two patients had cardioembolic stroke; the remaining 69 patients had non-cardioembolic stroke (including atherothrombotic stroke, lacunar stroke, or the other). Clinical variables and the plasma brain natriuretic peptide were evaluated in all patients.Results
Plasma brain natriuretic peptide was linearly associated with atrial fibrillation, heart failure, chronic renal failure, and left atrial diameter, independently (F4,126 = 27.6, p < 0.0001; adjusted R2 = 0.45). Furthermore, atrial fibrillation, mitral regurgitation, plasma brain natriuretic peptide (> 77 pg/ml), and left atrial diameter (> 36 mm) were statistically significant independent predictors of cardioembolic stroke in the multivariable setting (Χ2 = 127.5, p < 0.001).Conclusion
It was suggested that cardioembolic stroke was strongly predicted with atrial fibrillation and plasma brain natriuretic peptide. Plasma brain natriuretic peptide can be a surrogate marker for cardioembolic stroke. 相似文献12.
目的:探讨急性心肌梗死(AMI)早期脑钠肽(BNP)水平与左室重构及预后的关系。方法:用放射免疫法测定AMI患者早期血浆BNP水平;用超声心动图检查测量左室收缩末容积(ESV)、左室舒张末容积(EDV)、射血分数(EF)并通过计算得左室质量(LVM)。并根据左心室容积指标分组,左心室容积增加率〉20%为左心室重构组,否则为非重构组,比较两组血浆BNP水平。结果:重构组恢复期左心室舒张末期及收缩末期容积指数均高于非重构组(P〈0.01),亦高于急性期左心室容积(P〈0.01)。重构组早期血浆BNP浓度明显高于非重构组(P〈0.01),恢复期也较非重构组高(P〈0.01)。重构组早期BNP浓度与恢复期左心室容积及容积变化量之间呈正相关。结论:AMI早期BNP升高与急性期左室重构密切相关,血浆BNP浓度可以作为溶栓治疗再通的观察指标及预后判断依据。 相似文献

The predictive value of B-type natriuretic peptide (BNP) with respect to the occurrence of new-onset atrial fibrillation (AF) in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI) is unknown. The aim of this study was to evaluate whether BNP has a predictive value for the occurrence of new-onset AF in patients with STEMI treated by primary PCI. In 180 patients with STEMI treated by primary PCI, BNP concentrations were measured 24h after chest pain onset. The Receiver Operating Characteristic analysis was performed to identify the most useful BNP cut-off level for the prediction of AF. The patients were divided into the two groups according to calculated cut-off level: high BNP group (BNP≥720 pg/mL, n=33) and low BNP group (BNP<720 pg/mL, n=147). The incidence of AF was 5.0%, and occurred more frequently in high BNP group (7/33, 21.2%) than in low BNP group (2/147, 1.4%), (p<0.001). Patients with high BNP were older (p=0.017), had more often anterior wall infarction (p=0.015), higher Killip class on admission (p=0.038), higher peak troponin I (p=0.002), lower left ventricular ejection fraction (p=0.029) than patients with low BNP. After multivariate adjustment, BNP was an independent predictor of AF (OR 3.70, 95% CI 1.40-9.77, p=0.008). BNP independently predicts the occurrence of new-onset AF in STEMI patients treated by primary PCI. 相似文献

This study evaluated brain natriuretic peptide (BNP) release in acute myocardial infarction (AMI), absolute values as well as pattern of its release. There are two different patterns of BNP release in AMI; monophasic pattern--concentration in the first measurement is higher than in the second one, and biphasic pattern--concentration in the first measurement is lower than in the second one. We observed significance of biphasic and monophasic pattern of BNP release related to diagnostic and prognostic value. We included in this prospective observational study total of 75 AMI patients, 52 males and 23 females, average age of 62.3 +/- 10.9 years with range of 42 to 79 years. BNP was measured and pattern of its release was evaluated. In AMI group BNP levels were significantly higher than in controls (462.88 pg/mL vs. 35.36 pg/mL, p < 0.001). We found statistically significant real negative correlation (p < 0.05) between BNP concentration and left ventricle ejection fraction (LVEF) with high correlation coefficient (r = -0.684). BNP concentrations were significantly higher among patients in Killip class II and III compared to Killip class I; Killip class I BNP = 226.18 pg/mL vs. Killip class II 622.51 pg/mL vs. Killip class III 1530.28 pg/mL, p < 0.001. BNP concentrations were significantly higher in patients with; (i) myocardial infarction vs. controls; (BNP 835.80 pg/mL vs. 243.03 pg/mL); (ii) in pts with positive major adverse cardiac events (MACE) vs. negative MACE (BNP 779.08 pg/mL vs. 242.28 pg/mL, p < 0.001); (iii) in pts with positive compared to negative left ventricle (LV) remodelling (BNP 840.77 pg/mL vs. 341.41 pg/mL, p < 0.001). Group with biphasic pattern of BNP release had significantly higher BNP concentration compared to monophasic pattern group. In biphasic pattern group we found significant presence of lower LVEF, Killip class II and III, LV remodelling and MACE. We found that BNP is strong marker of adverse cardiac events in patients presenting with a myocardial infarction. In our AMI group we found significant elevation of BNP and it is suspected that second peak secretion is not only due to systolic dysfunction and subsequent remodeling of LV but also due to impact of ischaemia. Patients with biphasic pattern probably have worse prognosis due to severe coronary heart disease. Besides its diagnostic role as a simple blood marker of systolic function, BNP is also important prognostic marker who helps making clinical decision about early invasive vs. conservative management. 相似文献

In this study, we investigated the relationship between plasma B-type natriuretic peptide (BNP) levels and hemodynamics from cardiac catheterization in pediatric patients with atrial or ventricular septal defect. A total of 59 patients were studied including 80% of patients had Qp/Qs > 1.5 and 25% of patients had pulmonary hypertension. The mean BNP value and BNP z-score were 10.9?±?11.2 pg/mL and -0.28?±?1.7 (-2.85 to 3.29), respectively. There was a statistically significant linear correlation between BNP value and the size of defects (r?=?0.303, p?=?0.002) and a trend toward to positive correlation between BNP value and Qp/Qs ratio (r?=?0.183, p?=?0.166) among all patients. To identify patients with a Qp/Qs ratio >1.5, the sensitivity and specificity were 28%, 100% in all patients at a plasma BNP cut-off point of 15 pg/mL. We concluded that a BNP > 15 pg/mL would help identify patients who need further intervention. 相似文献

Using a radioimmunoassay for brain natriuretic peptide (BNP), we have measured levels of BNP-like immunoreactivity (-LI) in extract of the porcine heart, in perfusate from the isolated porcine heart and in porcine plasma. BNP-LI was detected in the extract of the atrium, though no detectable amount of BNP-LI (more than 1 ng/g) was present in the ventricle. The BNP-LI level in the porcine atrium was 148.7 +/- 23.3 ng/g. BNP-LI was also detected in the perfusate from the heart. Basal secretory rate of BNP was 3.18 +/- 0.76 ng/min. Moreover, BNP-LI was detected in porcine plasma at the concentration of 4.2 +/- 1.3 pg/ml. Gel filtration studies showed that BNP is present in the atrium as a large molecule and is secreted into the circulation as a small molecule. The percentage of BNP-LI to atrial natriuretic peptide (ANP)-LI was almost the same among the extract, the perfusate and the plasma (2-3 percent). These results indicate that BNP is synthesized in and is secreted into the circulation from the heat in a similar fashion as ANP. 相似文献
