OBJECTIVES Perfusion-metabolism mismatch in the subacute phase using thallium-201/radio iodinated beta-methyl-p-iodophenyl pentadecanoic acid (T1/BMIPP) dual scintigraphy is an indicator of viable myocardium in acute myocardial infarction. This study investigated early prediction of myocardial salvage from the T1/BMIPP mismatch and coronary flow velocity (CFV) patterns in patients with acute my...

Clinical investigations have suggested that the defects in SPECT images of a free fatty acid analog, I-123 beta-methyliodophenyl pentadecanoic acid (BMIPP) may indicate the ischemic risk area. To elucidate whether I-123 BMIPP can indicate the area at risk of ischemia, ex-vivo autoradiography was performed in rats whose left coronary artery was occluded for 60 min and then reperfused. I-123 BMIP...

PURPOSE Resting 123I-BMIPP scintigraphy can detect coronary artery disease based on persistent abnormality of myocardial fatty acid metabolism after transient ischemia. The present study aimed to determine the value of resting 123I-BMIPP scintigraphy in diagnosing coronary artery disease and predicting the therapeutic outcome in patients with chest pain symptom. METHOD Five hospitals particip...

UNLABELLED We investigated myocardial fatty acid metabolism in taxan-induced myocardial damage in patients with advanced lung cancer. PATIENTS AND METHODS Twenty-five patients with non-small-cell lung cancer were treated with taxan combined with carboplatin intravenously for three cycles. Myocardial SPECT imaging using 99mTc-methoxyisobutyl isonitrile (MIBI) and 123I-15-(p-iodophenyl)-3-(R,S)...

OBJECTIVES The aim of this study was to assess the performance of beta-methyl-p-[123I]-iodophenyl-pentadecanoic acid (BMIPP) single-photon emission computed tomography (SPECT) to detect acute coronary syndromes (ACS) in emergency department patients with chest pain. BACKGROUND Emergency department diagnosis of chest pain is problematic, often requiring prolonged observation and stress testing...

UNLABELLED Some have suggested that CD36, which is a multifunctional receptor with a molecular weight of 88 kDa, functions as a long-chain fatty acid (LCFA) transporter. We recently reported on a complete myocardial accumulation defect of the radiolabeled LCFA analog (123)I-15-(p-iodophenyl)-(R,S)-methylpentadecanoic acid (BMIPP) in patients with CD36 deficiency. In this study, we investigated ...

A 73-year-old man with aortic regurgitation was examined by 123I-alpha-methyl-p-iodophenylpentadecanoic acid (BMIPP) myocardial single photon emission computed tomography (SPECT) in 1995. Myocardial accumulation was not evident on either the early or the delayed image obtained 15 minutes and 3 hours, respectively, after injecting 123I-BMIPP. Flow cytometric analysis of CD36 expression in monocy...

We studied whether emission computed tomography (ECT) with 123I-labeled 15-(p-iodophenyl)-3R,S-methylpentadecanoic acid (BMIPP) shows myocardial distribution different from 201Tl in hypertrophic cardiomyopathy. In 10 patients with asymmetric septal hypertrophy (ASH), 5 with diffuse hypertrophy and 2 with apical hypertrophy, ECT was acquired 30 min (early) and 4 hr (late) after injection of 123I...

OBJECTIVE Takotsubo cardiomyopathy is a cardiac syndrome with an acute onset defined by chest symptoms and ST segment elevation on electrocardiograms. Takotsubo cardiomyopathy is sometimes misdiagnosed as acute myocardial infarction (AMI). Therefore a non-invasive diagnostic method is needed to be established for setting up appropriate strategies. The purpose of this study was to detect myocard...

Although various noninvasive methods have been used to detect vasospasm, none of them are sensitive enough for patients with sporadic attacks. Since abnormal fatty acid metabolism is observed in ischemic myocardium, 123I-beta-methyl-p-iodophenyl pentadecanoic acid (BMIPP), a radiolabeled fatty acid analog, has recently been proposed as a useful tracer for detecting myocardial damage. The aim of...
