Patient Information Non-Ischemic Cardiomyopathy BACKGROUND INFORMATION • Non-Ischemic cardiomyopathy is a generic term which includes all causes of decreased heart function other than those caused by heart attacks or blockages in the arteries of the heart. • The most common causes of non-ischemic cardiomyopathy are viral infection (viral myocarditis), drug reactions, inflammation or autoimmune reactions (lupus myocarditis, etc) or infiltrative processes (sarcoid, amyloid, etc). • Normal heart function, or ejection fraction (EF), is 55-65%. This means that with each beat, the heart pumps 55-65% of the blood inside the heart to the rest of the body. Cardiomyopathy implies some decrease in EF to less than 50% (which is considered borderline or low normal.) SYMPTOMS • Shortness of breath • Edema or swelling • Fatigue, especially with exertion • Unexplained weight gain • Shortness of breath when lying down DIAGNOSTIC TESTS • Ultrasound of the heart (Echocardiogram) • Stress testing (occasionally) • Angiogram (rarely) • Some blood tests may be helpful in making the diagnosis TREATMENT • Beta-blockers (atenolol, metoprolol, carvedilol, etc) can relax the heart, lower blood pressure and slow the heart to improve filling and pumping function. • Medications classified as ACE-inhibitors (lisinopril, enalapril, etc) or ARB’s (losartan, candesartan, etc) can also lower blood pressure, relax the heart and improved blood flow to the kidney. • Diuretics may be used to remove excess fluid. • Spironolactone can also be used to remove fluid and help relax the heart. • Pacemakers or defibrillators may be recommended in some cases. • Other treatments may be considered depending on the cause of the cardiomyopathy.

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 .

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.

Hypertrophic Cardiomyopathy Guide
Hypertrophic Cardiomyopathy Guide HYPERTROPHIC CARDIOMYOPATHY GUIDE What is hypertrophic cardiomyopathy? Hypertrophic cardiomyopathy (HCM) is a complex type of heart disease that affects the heart muscle. It causes thickening of the heart muscle (especially the ventricles, or lower heart chambers), left ventricular stiffness, mitral valve changes and cellular changes. Thickening of the heart muscle (myocardium) occurs most commonly at the septum. The septum is the muscular wall that separates the left and right side of aortic valve narrowed the heart. Problems occur outflow tract when the septum between outflow tract the heart’s lower chambers, leaky mitral mitral valve or ventricles, is thickened. valve septum The thickened septum may thickened cause a narrowing that can septum block or reduce the blood flow from the left ventricle Normal Heart Hypertrophic to the aorta - a condition Cardiomyopathy called “outflow tract obstruction.” The ventricles must pump harder to overcome the narrowing or blockage. This type of hypertrophic cardiomyopathy may be called hypertrophic obstructive cardiomyopathy (HOCM). HCM also may cause thickening in other parts of the heart muscle, such as the bottom of the heart called the apex, right ventricle, or throughout the entire left ventricle. Stiffness in the left ventricle occurs as a result of cellular changes that occur in the heart muscle when it thickens. The left ventricle is unable to relax normally and fill with blood. Since there is less blood at the end of filling, there is less oxygen-rich blood pumped to the organs and muscles. The stiffness in the left ventricle causes pressure to increase inside the heart and may lead to the symptoms described below.

Martinez1 Published online: 19 November 2018 # Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract Hypertrophic cardiomyopathy (HCM) is the most common hereditary cardiomyopathy characterized by left ventricular hyper- trophy and spectrum of clinical manifestation. Atrial fibrillation (AF) is a common sustained arrhythmia in HCM patients and is primarily related to left atrial dilatation and remodeling. There are several clinical, electrocardiographic (ECG), and echocardio- graphic (ECHO) features that have been associated with development of AF in HCM patients; strongest predictors are left atrial size, age, and heart failure class. AF can lead to progressive functional decline, worsening heart failure and increased risk for systemic thromboembolism. The management of AF in HCM patient focuses on symptom alleviation (managed with rate and/or rhythm control methods) and prevention of complications such as thromboembolism (prevented with anticoagulation). Finally, recent evidence suggests that early rhythm control strategy may result in more favorable short- and long-term outcomes. Keywords Atrial fibrillation . Hypertrophic cardiomyopathy .

A substantial proportion of these patients have abnormalities in the function and structure of coronary microcirculation due to endothelial and smooth muscle cell dysfunction. The coronary microcirculation has a fundamental role in the regulation of coronary blood flow in response to cardiac oxygen requirements. Impairment of this mechanism, defined as coronary microvascular dysfunction (CMD), carries an increased risk of adverse cardiovascular clinical outcomes. Coronary endothelial dysfunction accounts for approximately two-thirds of clinical conditions presenting with symptoms and signs of myocardial ischemia without obstructive coronary disease, termed “ischemia with non-obstructive coronary artery disease” (INOCA) and for a small proportion of “myocardial infarction with non-obstructive coronary artery disease” (MINOCA). More frequently, the clinical presentation of INOCA is microvascular angina due to CMD, while some patients present vasospastic angina due to epicardial spasm, and mixed epicardial and microvascular forms.

Hypertrophic Cardiomyopathy
HYPERTROPHIC CARDIOMYOPATHY Most often diagnosed during infancy or adolescence, hypertrophic cardiomyopathy (HCM) is the second most common form of heart muscle disease, is usually genetically transmitted, and comprises about 35–40% of cardiomyopathies in children. A diagram and echocardiogram comparing a normal heart and a heart with HCM are shown in figures 2a and 2b. Figure 2a- A normal Figure 2b- Multiple heart is shown on echocardiographic the left compared views of a normal to a heart with a heart on the left hypertrophic and a heart with cardiomyopathy on hypertrophic the right.

HCM affects up to 500,000 people in the United States. with children under age 12 accounting for less than 10% of all cases. According to the Pediatric Cardiomyopathy Registry, HCM occurs at a rate of five per 1 million children. “Hypertrophic” refers to an abnormal growth of muscle fibers in the heart. In HCM, the thick heart muscle is stiff, making it difficult for the heart to relax and for blood to fill the heart chambers. While the heart squeezes normally, the limited filling prevents the heart from pumping enough blood, especially during exercise. Although HCM can involve both lower chambers, it usually affects the main pumping chamber (left ventricle) with thickening of the septum (wall separating the pumping chambers), posterior wall or both. With hypertrophic obstructive cardiomyopathy (HOCM), the muscle thickening restricts the flow of blood out of the heart.
