Percutaneous coronary intervention (PCI) is a clinical procedure that is performed to treat stenosis of the coronary arteries of the heart. It involves the visualization of the blood vessels using coronary catheterization and X-ray imaging, followed by a coronary angioplasty using a balloon catheter. This ensures that the obstructed artery is inflated to relieve the narrowing. Stents are then deployed to keep the opening of the vessel intact. PCI is appropriate in case of stable coronary artery disease, or when coronary stenosis is more than 50%, or when angina symptoms are unresponsive to therapy. Percutaneous coronary angioplasty is a common procedure with no major complications. Mostly after three months of the procedure, the artery sufficiently heals and no longer requires the stent. This book contains some path-breaking studies in the field of coronary interventions. It outlines the procedures and practices of percutaneous coronary intervention in detail. This book includes contributions of experts and scientists which will provide innovative insights into cardiology.

Dialysis is a medical procedure which is performed in people with acute kidney failure or Stage 5 chronic kidney disease.

Chronic kidney disease (CKD) is a disease of the kidneys whereby they lose their function gradually over time. It also increases the risk of developing cardiovascular disease. The cause of mortality in individuals with CKD is cardiovascular disease. CKD progresses over a number of stages in increasing order of kidney damage. Kidney damage with glomerular filtration rate (GFR) greater than 90 ml/min and persistent albuminuria qualifies for stage 1. As it advances, GFR reduces progressively. Finally when GFR becomes less than 15 ml/min (stage 5), kidney failure sets in and the disease enters its end-stage. At this stage, a permanent renal replacement therapy is required for survival of the patient. Although renal replacement therapies can sustain people indefinitely, the quality of life is severely compromised. For individuals with hypertension, diabetes or obesity, above 60 years of age, or with a history of cardiovascular disease or kidney disease in family, screening is recommended. Research in CKD is aimed at the development of effective compounds for treating the disease. The efficacy of sulodexide and olmesartan medoxomil in the management of CKD is currently under investigation. This book provides comprehensive insights into chronic kidney disease. It presents researches and studies performed by experts across the globe. Those in search of information to further their knowledge will be greatly assisted by this book.

Cardiac arrhythmia or heart arrhythmia refers to a group of cardiac conditions, which is characterized by an irregular heartbeat. Arrhythmias can be of different types - supraventricular tachycardias, bradyarrhythmias, extra beats and ventricular arrhythmias. Arrhythmias are generally not considered serious but a person may become susceptible to complications such as heart failure or stroke, and cardiac arrest. Some common symptoms of arrhythmia are palpitations, which can be frequent, infrequent or continuous. If an arrhythmia causes a very fast, very slow or weak heartbeat, then lower blood pressure, light-headedness or dizziness are commonly experienced. Cardiac arrhythmias are generally detected during an auscultation of the heartbeat using a stethoscope, or by feeling peripheral pulses. The assessment of a cardiac abnormality using an electrocardiogram allows the diagnosis and evaluation of arrhythmia. Cardiac rhythm management can be achieved through medication, electro-cautery or cryo-cautery or by vagal maneuvres. Drugs such as anticoagulants and antiarrhythmics drugs may be prescribed. This book covers in detail the clinical perspectives in the development of cardiac arrhythmia. Different approaches, evaluations, methodologies and advanced studies on contemporary cardiology have been included herein.

Benign prostatic hyperplasia (BPH) is a clinical condition marked by an increase in size of the prostate gland. Frequent urination, inability to urinate and loss of bladder control are certain symptoms of BPH. The underlying mechanism responsible for the appearance of these symptoms is the enlarged prostate pressing on to the urethra. This makes the passage of urine out of the bladder difficult. Obesity, type 2 diabetes, family history and erectile dysfunction are certain risk factors. If BPH is not resolved, it may lead to urinary tract infections. The diagnosis of BPH is based on a rectal exam, a history of lower urinary tract symptoms, and an exclusion of other conditions with similar symptoms. Kidney function tests and prostate specific antigen allows kidney damage and prostate cancer to be evaluated. The management of this condition requires certain lifestyle alterations, such as moderating the consumption of caffeine products and alcohol, decreasing fluid intake before bedtime, increasing physical activity, among others. If the problem is not solved through medication, a transurethral resection of the prostate or a prostatic artery embolization may be needed. This book elucidates the concepts and innovative models around prospective developments with respect to diagnosis and treatment of benign prostatic hyperplasia. Through this book, we attempt to further enlighten the readers about the new concepts in clinical urology.

Inflammatory bowel disease (IBD) is a pathological condition of the colon and the small intestine. It is a complex multifactorial disease arising due to a genetic predisposition to the disease and interaction with environmental stimuli. Dietary patterns, alterations in the gut microbiome and loss of integrity of the intestinal epithelium can contribute to IBD. The common forms of inflammatory bowel disease are ulcerative colitis and Crohn's disease. Ulcerative colitis is restricted to the colon and rectum, whereas Crohn's disease affects any part of the gastrointestinal tract. Microscopically, the former extends only to the mucosa while the latter affects the full thickness of the bowel wall. Both these diseases have extra-intestinal manifestations such as arthritis, liver problems, eye problems, etc. Anemia is a common complication of both these diseases. This book explores all the important aspects of clinical gastroenterology in the present day scenario. It includes some of the vital pieces of work being conducted across the world, on inflammatory bowel disease. It is a resource guide for experts as well as students.

Liver fibrosis is a condition of the liver characterized by the excessive accumulation of extracellular matrix proteins such as collagen. Advanced liver fibrosis leads to cirrhosis of the liver. Cirrhosis leads to hepatocellular dysfunction and a high intrahepatic resistance to blood flow that results in hepatic insufficiency and portal hypertension. Liver biopsy is the standard procedure for diagnosing and assessing liver fibrosis. To determine the degree of liver damage, several scales such as Ishak fibrosis score (stages I-V) and METAVIR scoring system (stages I-IV) are used for staging of fibrosis. Other evaluations such as platelet count, ascites, Bonacini cirrhosis discriminant score and spider angiomata can help to diagnose cirrhosis. Recent evidence points to the reversibility of liver fibrosis even in its advanced stages. Typically, this may happen with a cessation of liver injury, via the successful treatment of the underlying disease. For patients with cirrhosis, liver transplantation is currently the only curative strategy with improved quality of life and better chances of survival. A lot of research is being undertaken to develop non-invasive and reliable markers of liver fibrosis, and liver specific antifibrotic therapies. This book aims to shed light on some of the unexplored aspects of liver fibrosis and the recent researches in this pathological condition. The objective of this book is to give a general view of the different aspects of its pathophysiology, diagnosis and management. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in hepatology at various levels.

Inflammatory bowel disease (IBD) is a set of inflammatory condition affecting colon and small intestine. There are two kinds of inflammatory bowel diseases - colitis and Crohn's disease. Crohn's disease can affect any part of the gastrointestinal tract from mouth to anus wherein colitis affects the colon and rectum. Common symptoms of Crohn's disease are abdominal pain, diarrhea, fever and weight loss. Common symptoms of colitis disease are abdominal pain, tenderness, loss of appetite, fatigue etc. These diseases are caused by a combination of genetic and environmental factors leading to inflammation and immunological responses to intestine. It can happen in any age group but it majorly occurs in teenagers and youngsters. The treatment of these diseases however depends on how severe they are.

Diarrhea mixed with blood and mucus, anemia, weight loss, abdominal pain, etc. may be observed. Extra-intestinal symptoms like painful arthritis may also occur. Depending on the extent of the disease, ulcerative colitis may be distal or extensive. A complete blood count, liver function tests, stool culture, endoscopy, sigmoidoscopy, biopsy, etc. aid in determining if a patient has ulcerative colitis. A therapeutic regime is designed such that remission is first induced, by achieving mucosal healing of the colitis and providing relief of symptoms. This is followed by treatment aimed at maintaining remission and preventing complications. The surgical removal of the large intestine is also an effective strategy if medication fails to control extra-intestinal symptoms, or if frank perforation, exsanguinating hemorrhage or carcinoma occur. This book contains some path-breaking studies in the diagnosis and treatment of ulcerative colitis. It outlines the signs and symptoms of ulcerative colitis in detail. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this medical condition.

Insulin resistance (IR) is a pathological condition characterized by the failure of the cells of the human body to respond normally to the hormone insulin. When the carbohydrate in food is digested, glucose gets released into the bloodstream, thus triggering the release of insulin. Normally, this activity initiates glucose absorption by the body cells which is used for energy, thus causing blood glucose levels to decrease and stay within an acceptable range even with a high carbohydrate intake. In the case of insulin resistance, cells are resistant to insulin and therefore cannot use it efficiently. This leads to high blood sugar. The body thus increases insulin production, which can contribute to obesity, type 2 diabetes or latent autoimmune diabetes in adults. Insulin resistance may arise due to pathologies such as liver diseases, hemochromatosis, obesity, metabolic syndrome, etc. It can also have genetic influences and be triggered by environmental factors, lifestyle choices or lack of a proper diet. This book discusses the fundamentals as well as modern approaches in the management of insulin resistance. It unravels the recent studies in the pathophysiology of insulin resistance. This book is a vital tool for all researching or studying this medical condition.

Hepatitis is a clinical condition in which the tissues of the liver become inflamed. It can be a temporary manifestation or a chronic condition lasting for six months or more. The former may resolve by itself, or may progress to chronic disease and even to acute liver failure. The chronic state may potentially lead to liver scarring, liver failure and even cancer. Viruses are primary cause of hepatitis. Other factors such as excessive alcohol consumption, certain toxins and medications, non-alcoholic steatohepatitis and autoimmune diseases may also contribute to this condition. Hepatitis A, B, C, D and E are the main types of viral hepatitis. Symptoms such as yellowing of the skin or the whites of the eyes, vomiting, abdominal pain, poor appetite or diarrhea may occur in this condition. Its diagnosis is generally possible through an evaluation of presenting signs and symptoms, substance use history, sexual history, blood tests and liver biopsy. Once diagnosed, hepatitis is treated depending on the type and severity of the disease and its underlying cause. Hepatitis is largely preventable through immunization, in particular the A, B and D types. Medication, healthy lifestyle, proper diet and weight loss are important for its management.
