BACKGROUND: The syndrome of heart failure (HF) is characterized by left ventricular dysfunction and a compensatory chronic over activation of the sympathetic nervous system. We wanted to investigate if the beneficial effects of exercise training (ET) in HF patients on optimal medical therapy (OMT) are associated with alterations in cardiac sympathetic activity. METHODS: Cardiac sympathetic activity was evaluated at baseline and after 12 weeks using metaiodobenzylguanidine scintigraphy in 23 patients with stable HF participating in the SmartEx trial...

BACKGROUND: Ischemia induced by psychological stress and depression is a common phenomenon in stable coronary artery disease (CAD). We evaluated the quality of life (QoL) of diabetic patients screened for CAD and assessed the prognostic value of mental and physical QoL scores to predict the development of new cardiac ischemia. METHODS: Prospective multicentre outcome study. The study comprised 400 asymptomatic diabetic patients without history or symptoms of CAD...

BACKGROUND: Single-photon emission computed-tomography (SPECT) allows the quantification of LV eccentricity index (EI), a measure of cardiac remodeling. We sought to evaluate the feasibility of EI measurement with SPECT myocardial perfusion imaging and its interactions with relevant LV functional and structural parameters. METHODS AND RESULTS: Four-hundred and fifty-six patients underwent myocardial perfusion imaging on a Cadmium-Zinc-Telluride (CZT) camera. The summed rest, stress, and difference scores were calculated...

OBJECTIVES: To compare major adverse cardiac event (MACE), downstream resource utilization, and direct cost of care for low-risk chest pain patients observed in the clinical decision unit (CDU) with exercise treadmill testing (ETT) and with stress-only myocardial perfusion imaging (sMPI). BACKGROUND: CDUs are poised to increase efficiency and resource utilization. However, the optimal testing strategy that would assure favorable outcomes while decreasing cost is not defined...

Atherosclerotic diseases account for nearly half of all deaths and are leading causes of adult disability. Our understanding of how atherosclerosis leads to cardiovascular disease events has evolved: from a concept of progressive luminal narrowing, to that of sudden rupture and thrombosis of biologically active atheroma. In concert with this conceptual shift, contemporary imaging techniques now allow imaging of biological processes that associate with plaque instability: active calcification and plaque inflammation...

BACKGROUND: Myocardial necrosis after myocardial infarction (MI) is common; extent and severity are however variable. The pattern is recognized by myocardial perfusion imaging (MPI) as fixed perfusion defects (FPD). The fate of such FPD is not well appraised. This study addressed this important issue in a large number of patients undergoing serial MPI in relation to type of intervening therapy. METHODS: Patients with prior MI or MPI-evidence of myocardial necrosis undergoing serial MPI without intervening acute coronary syndromes were included...

BACKGROUND: The aim of the present study was to evaluate the uptake of F18-NaF by the arterial wall in patients with high cardiovascular (CV) risk profile. The tracer uptake was assessed in relation to gender and the number of CV risk factors. METHODS AND RESULTS: 25 patients without known CV disease were included and evaluated by PET-CT with F18-NaF: 14 (56%) men and 11 (44%) women. The mean target-to-background ratio (TBR: max SUV/mean blood-pool SUV) but not the corrected uptake per lesion (CUL: max SUV - mean blood-pool SUV) was higher in men than women (TBR: 1...

BACKGROUND: Iodine-123 metaiodobenzylguanidine ((123)I-MIBG) scintigraphy is used as a noninvasive imaging method for assessing cardiac sympathetic nerve activity. We tested the hypothesis that renal (123)I-MIBG imaging is correlated with muscle sympathetic nerve activity (MSNA) in patients with primary hypertension. METHODS: Thirty-one consecutive patients with primary hypertension were included. Multiunit MSNA was recorded from the peroneal nerve to evaluate direct efferent sympathetic nerve activity...

BACKGROUND: Patient motion has been demonstrated to have a significant impact on the quality and accuracy of rubidium-82 myocardial perfusion PET/CT. This study aimed to investigate the effect on patient motion of two pharmacological stressing agents, adenosine and regadenoson. METHODS AND RESULTS: Dynamic data were retrospectively analyzed in 90 patients undergoing adenosine (n = 30), incremental adenosine (n = 30), or regadenoson (n = 30) rubidium-82 myocardial perfusion PET/CT...

BACKGROUND: The aim of this study was to assess the accumulation pattern of 18F-FDG in fasting patients with takotsubo cardiomyopathy (TTC) and to correlate the results with perfusion scintigraphy and echocardiography. METHODS: 18 consecutive patients with TTC were identified by clinical symptoms, cardiac catheterization, and echocardiography. Coronary angiography (CA) and transthoracic echocardiography (TTE) were performed on the day of the onset of symptoms. An assessment of myocardial perfusion (99mTc-MIBI) and glucose metabolism (18F-FDG) was performed within 18 days...

BACKGROUND: Image acquisition by short-time single-photon emission-computed tomography (SPECT) has been made feasible by IQ·SPECT. The aim of this study was to generate normal databases (NDBs) of thallium-201 ((201)Tl) myocardial perfusion imaging for IQ·SPECT, and characterize myocardial perfusion distribution. METHODS AND RESULTS: We retrospectively enrolled 159 patients with a low likelihood of cardiac diseases from four hospitals in Japan. All patients underwent short-time (201)Tl myocardial perfusion IQ·SPECT with or without attenuation and scatter correction (ACSC) in either supine or prone position...

BACKGROUND: Quantitative uptake of Technetium 99 m-pyrophosphate (TcPYP) is sensitive and specific for diagnosing transthyretin cardiac amyloidosis (ATTR). We sought to examine the association between TcPYP uptake intensity and echocardiographic measures of disease severity and clinical outcomes. METHODS AND RESULTS: A retrospective analysis was performed of 75 patients who underwent TcPYP scintigraphy. Planar images were evaluated semiquantitatively and using heart-to-contralateral lung (H/CL) ratio...

BACKGROUND: Traditional cardiovascular (CV) risk factors have limited predictive value of CV mortality in patients with chronic kidney disease (CKD, creatinine clearance less than 60 mL/minute per 1.73 m(2)). The aim of this study was to evaluate incremental and independent prognostic value of single-photon emission computerized tomography-myocardial perfusion imaging (SPECT-MPI) across continuum of renal function. METHODS: We retrospectively studied 11,518 (mean age, 65 ± 12 years; 52% were men) patients referred for a clinical indication of SPECT-MPI between April 2004 and May 2009...

We recently showed that Quantitative Perfusion SPECT (QPS), Emory Cardiac Toolbox (ECTb) and 4-Dimension-Myocardial SPECT (4DM) yielded discordant results in the assessment of perfusion defect size (PDS) in patients with known or suspected coronary artery disease. In this report, we examined the sources of variability in the measurement of PDS using ECTb (VarECTb), 4DM (Var4DM) and QPS (VarQPS) and found that gender is a source of variability in the assessment of PDS. In 120 patients, VarECTb was lower in men, compared with women, whereas Var4DM and VarQPS were similar between both genders...
