18. Fatty acid uptake is preserved in chronically dysfunctional but viable myocardium

Abstract

[(super 18)F]FTHA and positron emission tomography in the fasting state of viable and normal cardiac regions were utilized to investigate the fatty acid uptake kinetics in the chronically dysfunctional heart. Results have shown that the uncoupling of substrate uptake and contractile function occurred in the chronically dysfunctional but viable myocardium in humans.

Abstract

OBJECTIVES: The purpose of this study was to compare myocardial blood flow (MBF) and myocardial flow reserve (MFR) estimates from rubidium-82 positron emission tomography ((82)Rb PET) data using 10 software packages (SPs) based on 8 tracer kinetic models. BACKGROUND: It is unknown how MBF and MFR values from existing SPs agree for (82)Rb PET. METHODS: Rest and stress (82)Rb PET scans of 48 patients with suspected or known coronary artery disease were analyzed in 10 centers. Each center used 1 of 10 SPs to analyze global and regional MBF using the different kinetic models implemented. Values were considered to agree if they simultaneously had an intraclass correlation coefficient >0.75 and a difference

23. 82Rb-PET MPQ: Do normal values exist?

Author

Nesterov, Sergey V. and Knuuti, Juhani M.

Abstract

Based on the finding in CCTA, the patients were classified as (a) normal (no stenosis, N = 153), (b) with non-obstructive coronary artery disease (CAD) (< 50%, N = 99), and (c) with obstructive CAD (>= 50%, N = 105). i " To get an answer, they performed a study of 357 patients that underwent 82Rb-PET/CT and integrated coronary CT angiography (CCTA). Not surprisingly, the global stress myocardial blood flow (sMBF) (and myocardial flow reserve, MFR) were higher 3.61 ± 0.71 mL-min-g (3.08 ± 0.84) in normal patients than in patients with obstructive CAD 3.04 ± 0.77 mL-min-g (2.68 ± 0.79). The authors used CT coronary angiography to rule out CAD in patients with suspected ischemic heart disease. [Extracted from the article]

Abstract

Advances in medical imaging now make it possible to investigate any patient with cardiovascular disease using multiple methods which vary widely in their technical requirements, benefits, limitations, and costs. The appropriate use of alternative tests requires their integration into joint clinical diagnostic services where experts in all methods collaborate. This statement summarizes the principles that should guide developments in cardiovascular diagnostic services. [ABSTRACT FROM PUBLISHER]
