Diabetes Reduces Left Ventricular Ejection Fraction-Irrespective Of
European Journal of Endocrinology (2011) 165 945–951 ISSN 0804-4643 CLINICAL STUDY Diabetes reduces left ventricular ejection fraction-irrespective of presence and extent of coronary artery disease Niklas F Ehl1, Michael Ku¨hne1, Miriam Brinkert1, Jan Mu¨ller-Brand2 and Michael J Zellweger1 Departments of 1Cardiology and 2Nuclear Medicine, University Hospital, Petersgraben 4, CH - 4031 Basel, Switzerland (Correspondence should be addressed to M J Zellweger; Email: [email protected]) Abstract Background: It is not clear whether diabetes reduces systolic left ventricular function (left ventricular ejection fraction, LVEF) irrespective of coronary artery disease (CAD). The aim of this study was to compare the LVEF between diabetic and non-diabetic patients with respect to the extent of CAD. Methods and results: Consecutive patients undergoing stress myocardial perfusion SPECT (MPS) were evaluated. MPS was interpreted using a 20-segment model with a five-point scale to define summed stress score (SSS), summed rest score, and summed difference score. LVEF was measured by gated SPECT and then compared with respect to diabetic status and SSS categories. Of 2635 patients, data of 2400 was available. Of these, 24% were diabetic, mean age was 64G11y, and 31% were female. Diabetics had a significantly lower LVEF compared with non-diabetics regardless of the extent of CAD: 53G13 and 55G13% respectively (PZ0.001). Diabetics and non-diabetics did not differ significantly in the distribution of SSS categories. Diabetes was an independent predictor of decreased LVEF (odds ratio 1.6, 95% confidence interval 1.2–2.0; P!0.001). Conclusion: Diabetics had a lower LVEF than non-diabetics. -
Ischemic Cardiomyopathy: Symptoms, Causes, & Treatment
Ischemic Cardiomyopathy Ischemic cardiomyopathy is a condition that occurs when the heart muscle is weakened due to insufficient blood flow to the heart's muscle. This inhibits the heart's ability to pump blood and can lead to heart failure. What Is Ischemic Cardiomyopathy? Ischemic cardiomyopathy (IC) is a condition that occurs when the heart muscle is weakened. In this condition, the left ventricle, which is the main heart muscle, is usually enlarged and dilated. This condition can be a result of a heart attack or coronary artery disease, a narrowing of the arteries. These narrowed arteries keep blood from reaching portions of your heart. The weakened heart muscle inhibits your heart’s ability to pump blood and can lead to heart failure. Symptoms of IC include shortness of breath, chest pain, and extreme fatigue. If you have IC symptoms, you should seek medical care immediately. Treatment depends on how much damage has been done to your heart. Medications and surgery are often required. You can improve your long-term outlook by making certain lifestyle changes, such as maintaining a healthy diet and avoiding high-risk behaviors, including smoking. Symptoms of Ischemic Cardiomyopathy You can have early-stage heart disease with no symptoms. As the arteries narrow further and blood flow becomes impaired, you may experience a variety of symptoms, including: shortness of breath extreme fatigue dizziness, lightheadedness, or fainting chest pain and pressure (angina) heart palpitations weight gain swelling in the legs and feet (edema) and abdomen difficulty sleeping cough or congestion caused by fluid in the lungs If you have these symptoms, seek emergency medical care or call 9-1-1. -
Myocarditis and Cardiomyopathy
CE: Tripti; HCO/330310; Total nos of Pages: 6; HCO 330310 REVIEW CURRENT OPINION Myocarditis and cardiomyopathy Jonathan Buggey and Chantal A. ElAmm Purpose of review The aim of this study is to summarize the literature describing the pathogenesis, diagnosis and management of cardiomyopathy related to myocarditis. Recent findings Myocarditis has a variety of causes and a heterogeneous clinical presentation with potentially life- threatening complications. About one-third of patients will develop a dilated cardiomyopathy and the pathogenesis is a multiphase, mutlicompartment process that involves immune activation, including innate immune system triggered proinflammatory cytokines and autoantibodies. In recent years, diagnosis has been aided by advancements in cardiac MRI, and in particular T1 and T2 mapping sequences. In certain clinical situations, endomyocardial biopsy (EMB) should be performed, with consideration of left ventricular sampling, for an accurate diagnosis that may aid treatment and prognostication. Summary Although overall myocarditis accounts for a minority of cardiomyopathy and heart failure presentations, the clinical presentation is variable and the pathophysiology of myocardial damage is unique. Cardiac MRI has significantly improved diagnostic abilities, but endomyocardial biopsy remains the gold standard. However, current treatment strategies are still focused on routine heart failure pharmacotherapies and supportive care or cardiac transplantation/mechanical support for those with end-stage heart failure.

ICD-10-CM Documentation and Coding Best Practices
ICD-10-CM Documentation and Coding Best Practices Cardiomyopathy Cardiomyopathy refers to diseases of the heart muscle, which can become enlarged, thick or rigid. In rare cases, cardiac muscle tissue can be replaced with scar tissue. As the condition worsens, the heart becomes weaker and less able to pump blood through the body or to maintain a normal electrical rhythm. Causes Risk factors that can increase the possibility of developing cardiomyopathy include: coronary artery disease, a history of heart attack (s), viral infections that cause heart inflammation, long-term hypertension or alcoholism, obesity, and diabetes to name a few. However, in most cases the exact cause is usually unknown (called primary or idiopathic cardiomyopathy). Symptoms Some patients will never have symptoms; others will not develop them until later in the disease. Symptoms can include: • Fatigue • Shortness of b reath or trouble breathing (dyspnea) • Dizziness, lightheadedness or fainting • Swelling in the ankles, feet, legs, abdomen and neck veins Treatment Treatment depends on the type of cardiomyopathy, the severity of symptoms, and the patient’s age and overall health. • Lifestyle changes can help manage condition(s) that may be causing cardiomyopathy. Recommendations include: o Consuming a heart healthy diet, engaging in physical activity, losing excess weight, giving up smoking, avoiding alcohol and illegal drugs, getting enough sleep, and reducing stress • Medicines may be p rescribed to: o Lower blood pressure (ACE inhibitors, angiotensin II receptor blo ckers, beta blockers, calcium channel blockers ) o Slow the heart rate (beta blockers, calcium channel blockers, digoxin) o Prevent arrhythmias (antiarrhythmics) o Remove excess fluid and sodium (diuretics) o Prevent blood clots (anticoagulants) • Alcohol septal ablation • Surgery o Septal myectomy – option for severe cases of obstructive hypertrophic cardiomyopathy Surgically implanted devices o . -

Functional Neuroimaging of Normal Human Sleep by Positron Emission Tomography
J. Sleep Res. (2000) 9, 207±231 Functional neuroimaging of normal human sleep by positron emission tomography P. MAQUET Cyclotron Research Centre, University of LieÁ ge, LieÁ ge, Belgium Accepted in revised form 23 April 2000; received 28 September 1999 SUMMARY Functional neuroimaging using positron emission tomography has recently yielded original data on the functional neuroanatomy of human sleep. This paper attempts to describe the possibilities and limitations of the technique and clarify its usefulness in sleep research. A short overview of the methods of acquisition and statistical analysis (statistical parametric mapping, SPM) is presented before the results of PET sleep studies are reviewed. The discussion attempts to integrate the functional neuroimaging data into the body of knowledge already acquired on sleep in animals and humans using various other techniques (intracellular recordings, in situ neurophysiology, lesional and pharmacological trials, scalp EEG recordings, behavioural or psycholo- gical description). The published PET data describe a very reproducible functional neuroanatomy in sleep. The core characteristics of this `canonical' sleep may be summarized as follows. In slow-wave sleep, most deactivated areas are located in the dorsal pons and mesencephalon, cerebellum, thalami, basal ganglia, basal forebrain/ hypothalamus, prefrontal cortex, anterior cingulate cortex, precuneus and in the mesial aspect of the temporal lobe. During rapid-eye movement sleep, signi®cant activations were found in the pontine tegmentum, thalamic nuclei, limbic areas (amygdaloid complexes, hippocampal formation, anterior cingulate cortex) and in the posterior cortices (temporo-occipital areas). In contrast, the dorso-lateral prefrontal cortex, parietal cortex, as well as the posterior cingulate cortex and precuneus, were the least active brain regions. -
Differential Patterns of Blood Oxygenation in the Prefrontal Cortex

However, a recent study has shown that near-infrared spectroscopy (NIRS) performed during a cognitive task can be a powerful tool to differentiate between these two disorders. Here, we evaluated verbal fluency task performance during NIRS in 15 patients diagnosed with MAP and 19 with schizophrenia matched for age and sex. We used prefrontal probes and a 24-channel NIRS machine to measure the relative concentrations of oxyhaemoglobin every 0.1 s during the task. For each patient, the neurocognitive function and clinical psychopathology were evaluated using the Positive and Negative Symptom Scale (PANSS), and the Brief Assessment of Cognition in Schizophrenia (BACS). Oxyhaemoglobin changes in the prefrontal cortex were significantly higher in the MAP group compared to those in the schizophrenia group, particularly in the right dorsolateral prefrontal cortex. In contrast, we found no significant difference in PANSS and BACS scores. Our findings suggest that NIRS measurement could be applied to differentiate patients with MAP from those with schizophrenia, even in cases where clinical symptoms are similar. -
Ischemic Cardiomyopathy: Contemporary Clinical Management
Chapter 7 Ischemic Cardiomyopathy: Contemporary Clinical Management BurhanBurhan Sheikh Alkar, Sheikh Alkar, Gustav MattssonGustav Mattsson and PeterPeter Magnusson Magnusson Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.76723 Abstract Ischemic cardiomyopathy, disease of the heart muscle due to coronary artery disease, is the most common cardiomyopathy. It is often difficult to discern the etiology of heart failure, and often there are multiple underlying causes. Ischemic cardiomyopathy most often pres - ents with a dilated morphology with wall motion defects and a history of previous myocar - dial infarction or confirmed coronary artery disease. Mechanisms of myocardial depression in ischemia are necrosis of myocardial cells resulting in irreversible loss of function or reversible damage, either short term through myocardial stunning or long term through hibernation. In ischemic cardiomyopathy, echocardiography may be extended with stress testing or other imaging modalities such as myocardial scintigraphy and cardiac magnetic resonance tomography. Coronary angiography is often considered a gold standard; how - ever, other modalities such as positron emission tomography can be needed to detect small vessel disease. Cardiac revascularization, through percutaneous coronary intervention and coronary artery bypass grafting, both in acute coronary syndrome and in stable coronary artery disease, relieves symptoms and improves prognosis. Therapy should aspire to treat ischemia, arrhythmias in addition to heart failure management, which includes device therapy with cardiac resynchronization therapy, implantable cardioverter defibrillators, and mechanical support as bridging or destination therapy in end-stage disease. Keywords: cardiomyopathy, coronary artery disease, heart failure, ischemic, myocardial infarction 1. Introduction Disease of the heart muscle, cardiomyopathy, appears in various disease manifestations, which are often either poorly defined or difficult to distinguish in clinical practice. -
