Role of ¹²³I-BMIPP and serum B-type natriuretic peptide for the evaluation of patients with heart failure.

Introduction: Myocardial scintigraphy with ¹²³I-15-(p-iodophenyl)-3-methyl pentadecanoic acid (¹²³I-BMIPP) is used to evaluate impaired fatty acid metabolism. B-type natriuretic peptide (BNP), which is secreted by the ventricular myocardium on stretching and/or pressure overload, is a useful cardiac biomarker. This study aimed to evaluate the usefulness of ¹²³I-BMIPP imaging and serum BNP levels in patients with heart failure (HF).

Discrepancy between myocardial perfusion and fatty acid metabolism following acute myocardial infarction for evaluating the dysfunctional viable myocardium.

Objective: Following acute myocardial infarction (AMI) the area of myocardial perfusion and metabolism mismatch is designated as dysfunctional viable myocardium. (123)I-beta-methyl iodophenyl pentadecanoic acid (BMIPP) is clinically very useful for evaluating myocardial fatty acid metabolism, and (99)mTc-Tetrofosmin (TF) is a widely used tracer for myocardial perfusion. This study was designed to evaluate the degree of discrepancy between BMIPP and TF at the subacute state of AMI.

The washout rate of (123)I-BMIPP and the evolution of left ventricular function in patients with successfully reperfused ST-segment elevation myocardial infarction: comparisons with the echocardiography.

The evolution of the oxidative metabolism of (11)C acetate parallels the recovery of left ventricular(LV) contraction following acute myocardial infarction(AMI). This study was designed to unravel, for the first time, the impact of the global washout rate(WR) of (123)I-beta-methyl-p-iodophenylpentadecanoic acid (BMIPP) on the recovery of LV function followingAMI, as evidenced from conventional echocardiography.Twenty consecutive patients (age: 58 +/- 13 years; 16 males and 4 females) with ST-segment elevation myocardial infarction (STEMI) were enrolled and all of them underwent successful percutaneous coronary intervention (PCI).

(123)I-BMIPP and (99m)Tc-TF discordance on myocardial scintigraphy and it's correlation with functional recovery following acute myocardial infarction: role of conventional echocardiography.

(123)I-beta-methyl-iodophenyl pentadecanoic acid (BMIPP) and (99m)Tc-Tetrofosmin (TF) mismatch designated as stunned myocardium having both systolic and diastolic components. The degree of mismatch might reflect subsequent functional improvement, and this study was designed to unravel the impact of mismatched defect score (MMDS) on recovery of both systolic and diastolic function following acute myocardial infarction (AMI). Forty patients with recent AMI were recruited, and all of them underwent emergency percutaneous coronary intervention.

Fatty acid metabolism and myocardial perfusion imaging for the evaluation of global left ventricular dysfunction following acute myocardial infarction: comparisons with echocardiography.

Background: Myocardial fatty acid metabolic imaging with beta-methyl iodophenyl pentadecanoic acid (BMIPP) and perfusion imaging with tetrofosmin (TF) combined can predict post ischemic salvageable myocardium and persistent left ventricular (LV) dysfunction. This study was designed for the first time to assess systolic, diastolic and global LV dysfunction considering BMIPP and TF mismatched defect score (MMDS), and comparing this approach with the conventional Doppler echocardiography.

Methods: Thirty four patients with first acute myocardial infarction (AMI) were enrolled, and all of them underwent percutaneous coronary intervention (PCI).
