Our study aimed to assess predictors of the stress test technique used and to evaluate the impact of exercise level achieved on risk stratification in patients with asymptomatic type 2 diabetes without a previous coronary artery disease. Little is known whether co-morbidities of these patients predict the stress technique and whether physical performance provides risk stratification: 400 patients underwent clinical evaluation and myocardial perfusion scintigraphy (MPS) using physical or pharmacological stress...

OBJECTIVES: In stable coronary artery disease (CAD), coronary revascularisation may reduce mortality of patients with a certain amount of left ventricular myocardial ischaemia. However, revascularisation does not always follow the guidance suggested by ischaemia testing. We compared outcomes in patients without ischaemia who had either revascularisation or medical treatment. DESIGN AND POPULATION: Based on registries, 1327 consecutive patients with normal myocardial perfusion scintigraphy (MPS) and 278 with fixed perfusion defects were followed for a median of 6...

Sympathetic nervous system plays a pivotal role in essential hypertension and in the development of left ventricular hypertrophy. Moreover, cardiac sympathetic dys-regulation has been demonstrated as a key con-causal factor in the genesis and progression of pathologic conditions such as congestive heart failure and ischemic heart disease to which hypertension predisposes as a risk factor. However, despite its fundamental role in cardiac pathophysiology, the evaluation of cardiac sympathetic nervous system has never gained a wide clinical application, remaining mostly a research tool...

A 75-year-old woman who had previously been diagnosed with Bland-White-Garland syndrome was admitted to our hospital for acute decompensated heart failure (ADHF). Following her recovery from ADHF, pharmacologic stress myocardial scintigraphy revealed myocardial ischemia in the basal anterior area of the left ventricle. Moreover, myocardial scintigraphy showed the improvement of the myocardial ischemia after 6 months of nicorandil administration.

Polymyositis is an idiopathic inflammatory myopathy, characterized by proximal muscle weakness and sometimes extramuscular manifestations. We report the case of a 51-year-old male, with history of complete heart block, which required pacemaker implantation, and subsequently heart failure, presenting to the emergency department with worsening of dyspnea and peripheral edema. He was admitted to the Internal Medicine ward with acute heart failure and started on diuretic therapy. During hospitalization, he was discovered to have marked rhabdomyolysis...

BACKGROUND: The etiology of spontaneous dissection of coronary artery (SDCA) is not well understood yet. Different studies have linked this entity to pregnancy, physical stress, collagen diseases and vasculitis. In general, patients do not exhibit the classic risk factors for coronary artery disease, which mandates the suspicion of this condition, especially in young adults with acute coronary syndrome. CASE REPORT: In this article, we report the case of a 63-year old male patient, asymptomatic, who came for periodic evaluation and after evaluation by exercise and myocardial scintigraphy had high suspicion for severe coronary artery disease and underwent coronary angiography, which showed spontaneous dissection of the left and right branches of the coronary arteries...

BACKGROUND: Diabetes mellitus type 2 (T2DM) is a significant risk factor for the development of cardiovascular diseases (CVDs). In a previous microarray study of internal mammary arteries from patients with and without T2DM, we observed several elastin-related genes with altered mRNA-expression in diabetic patients, namely matrix metalloproteinase 2 (MMP-2), lysyl oxidase (LOX) and elastin itself. In this study we investigate whether the serum concentrations of elastin-related proteins correlate to signs of CVD in patients with T2DM...

OBJECTIVE: Scans without evidence of dopaminergic deficits (SWEDDs) in dopamine transporter single-photon emission computed tomography (DAT-SPECT) are found in 3.6-19.6% of patients with clinically suspected Parkinson's disease (PD). We investigated whether combined use of (123)I-meta-iodobenzylguanidine (MIBG) myocardial scintigraphy would be helpful to differentiate PD among SWEDDs patients. PATIENTS AND METHODS: 145 patients with clinically suspected PD underwent both DAT-SPECT and MIBG myocardial scintigraphy...

BACKGROUND: The oxygen (O2 ) pulse curve obtained at cardiopulmonary exercise testing provides information on cardiorespiratory fitness and the presence of cardiovascular disease. O2 pulse abnormalities have been attributed to myocardial ischemia, among other conditions, but the predictors of abnormal O2 pulse curves are not completely known. HYPOTHESIS: Perfusion abnormalities detected by myocardial perfusion scintigraphy (MPS) may be associated with abnormal O2 pulse curves...

OBJECTIVE: Patients with Parkinson's disease (PD) may exhibit symptoms of sympathetic dysfunction that can be measured using (123)I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy. We investigated the relationship between microstructural brain changes and (123)I-MIBG uptake in patients with PD using voxel-based morphometry (VBM) and diffusion tensor imaging (DTI) analyses. METHODS: This retrospective study included 24 patients with PD who underwent 3 T magnetic resonance imaging and (123)I-MIBG scintigraphy...

BACKGROUND: It is commonly known that headaches are induced by intake of specific food, drink, and/or additive. In addition, some patients experience postprandial headache independent of ingestion of specific items. Currently, information on the pathophysiology underlying this particular type of headache is scarce. CASE REPORTS: We report two cases in which headaches were observed after each meal. Postprandial hypotension was demonstrated in both cases. Tonometry-based continuous blood pressure measurement during head-up tilt revealed sympathetic dysfunction...

In this study, we compared the patients who underwent coronary angiography (CAG), followed by revascularization by coronary artery stent implantation according to the CAG results without any evidence of ischemia with myocardial perfusion scintigraphy (MPS), and the patients who underwent revascularization by coronary artery stent implantation following the detection of ischemia in MPS before CAG in terms of the mortality and hospitalization due to acute coronary syndrome (ACS). Between January 2009 and January 2016, a total of 407 patients (52% males, 48% females; mean age: 66 ± 9 years; range: 40-85 years) who underwent CAG following diagnosis of stable angina and underwent coronary artery stenting were retrospectively analyzed...

We report a case with 46-year-old man diagnosed with mitochondrial cardiomyopathy in the dilated phase of hypertrophic cardiomyopathy. Since cardiac magnetic resonance imaging, beta-methyl-p-(123)I-iodophenyl-pentadecanoic myocardial scintigraphy, and positron emission tomography/computed tomography revealed no remarkable findings, we performed electron microscopic examination, which aided in diagnosing mitochondrial cardiomyopathy. Muscle biopsy was also compatible with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes and DNA analysis also concluded it...

Anomalies in coronary arteries (CA) are an important issue in cardiology and cardiovascular surgery. Specifically the anomalous origin of the right coronary artery (RCA) is of special importance because it is the most frequent anomaly. Clinical practice guidelines recommend the revascularization treatment in cases of interarterial pathway and documented myocardial ischemia and when hypoplasia, compression or obstruction is evident. We report two different cases of patients with anomalous origin of RCA and associated interarterial pathway...

Pure autonomic failure is challenging as it can be the presenting feature of a central nervous system syncleinopathy such as Parkinson's disease (PD) or multiple system atrophy (MSA). Because the prognosis of MSA and PD is so different, predictive features for a possible conversion can be extremely valuable. In this paper, we report three cases (two with autopsy-proven diagnosis) that had isolated AF for many years before converting to MSA or PD. Of all the tests that were performed during the premotor stage, Iodine-123-meta-iodobenzylguanidine (MIBG) myocardial scintigraphy was predictive of the conversion to MSA...

BACKGROUND: The American College of Cardiology (ACC) Appropriate Use Criteria (AUC) for radionuclide myocardial perfusion scans (MPS) was developed to promote its rational use in the assessment of stable ischaemic heart disease (IHD). We sought to validate the applicability of this document in the Australian context. METHODS: 1009 consecutive patients who underwent MPS were retrospectively audited at a single major metropolitan hospital in Victoria, Australia. Appropriateness was assigned based on the 2013 ACC AUC, and common indications and predictors of positive scan results were examined...

PURPOSE: Myocardial sympathetic imaging with (123)I-meta-iodobenzylguanidine ((123)I-mIBG) has gained clinical momentum. Although the need for standardization of (123)I-mIBG myocardial uptake has been recognized, the availability of practical clinical standardization approaches is limited. The need for standardization includes the heart-to-mediastinum ratio (HMR) and washout rate with planar imaging, and myocardial defect scoring with single-photon emission computed tomography (SPECT)...

The Dementia with Lewy Bodies (DLB) Consortium has refined its recommendations about the clinical and pathologic diagnosis of DLB, updating the previous report, which has been in widespread use for the last decade. The revised DLB consensus criteria now distinguish clearly between clinical features and diagnostic biomarkers, and give guidance about optimal methods to establish and interpret these. Substantial new information has been incorporated about previously reported aspects of DLB, with increased diagnostic weighting given to REM sleep behavior disorder and (123)iodine-metaiodobenzylguanidine (MIBG) myocardial scintigraphy...

INTRODUCTION: The standard treatment of sinus node dysfunction (SND) is the pacemaker implantation, and the ideal methodology for the management of atrial fibrillation (AF) is rhythm control, but this is sometimes very hard to accomplish. For such actions, complete isolation of all pulmonary veins (PVI) is currently widely accepted as the best endpoint. CASE PRESENTATION: In this case, we report a female patient, 81 years old, with controlled hypertension, without coronary artery disease, bearer of bilateral knee replacement, and dual chamber pacemaker implanted 1...

Introduction. Cardiovascular (CV) diseases are a major cause of death in rheumatoid arthritis (RA) patients. Novel biomarkers [B-type natriuretic peptide (BNP); osteoprotegerin (OPG)/receptor activator of nuclear factor-kappa B ligand (RANKL) ratio; and dickkopf-1 (DKK-1)] have been used in CV risk assessment. We analysed, in established RA patients, the presence of silent myocardial ischemia and its association with clinical variables, BNP, and bone and atheroma biomarkers. Methods. From a single-center tertiary referral hospital, RA patients asymptomatic for CV disease were submitted to myocardial perfusion scintigraphy (MPS) under adenosine stress and biomarkers measurements...
