چکیده

PLASMA NOREPINEPHRINE CONCENTRATIONS, which increase in patients with congestive heart failure, reflect the severity of the disease and are closely related to prognosis.1 Because sympathetic activity is enhanced with increasing severity of congestive heart failure, the severity and prognosis of congestive heart failure can be evaluated based on parameters determined by I-123 metaiodobenzylguanidine (MIBG) scintigraphy.2,3 Neurohumoral factors, such as atrial (A-type) natriuretic peptide (ANP) and brain (B-type) natriuretic peptide (BNP), have also been reported to be useful in diagnosing and evaluating the severity of congestive heart failure.4 This report describes a dilated cardiomyopathy patient who was admitted to our hospital due to congestive heart failure, which was treated with a β-blocker, and who was followed up based on BNP levels and MIBG scintigraphy.

Dilated cardiomyopathy relieved as a result of beta-blocker therapy: a case report--key points in assessment of prognosis based on MIBG myocardial scintigraphy and BNP levels.

A 48-year-old male patient was admitted to our hospital with dyspnea accompanied by orthopnea. Chest x-rays showed a cardiothoracic ratio of 68% and pulmonary congestion. He was diagnosed with dilated cardiomyopathy. Beta-Blocker (carvedilol) therapy was initiated on Day 22 of the disease using a small initial dose. He was followed up based on BNP levels and MIBG scintigraphy. The H/M ratio and...

The value of myocardial perfusion imaging in differentiating between idiopathic dilated cardiomyopathy from the ischemic form [Persian]

Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...

Prediction of long-term cardiac events by 123I-MIBG imaging after acute myocardial infarction and reperfusion therapy

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

Decline of plasma brain natriuretic peptide level after carvedilol therapy to treat dilated cardiomyopathy presenting with mechanical alternans.

Mechanical alternans is observed in patients with severe left ventricular dysfunction. We report a case of dilated cardiomyopathy with mechanical alternans. He presented with a remarkable decrease in plasma brain natriuretic peptide (BNP) levels after beta-blocker therapy despite persistency of the mechanical alternans. Mechanical alternans may persist after improvement of hemodynamics, diastol...

Comparison between Brain Natriuretic Peptide and Calcitonin Gene Related Peptide in Children with Dilated Cardiomyopathy

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...
