Hypertrophic Cardiomyopathy

Show More
Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disease, which affects the structure of heart muscle tissue. The clinical symptoms include arrhythmias, progressive heart failure, and even sudden cardiac death but the mutation carrier can also be totally asymptomatic. To date, over 1400 mutations have been linked to HCM, mostly in genes encoding for sarcomeric proteins. However, the pathophysiological mechanisms of the disease are still largely unknown. Two founder mutations for HCM in Finland are located in myosin-binding protein C (MYBPC3-Gln1061X) and α-tropomyosin (TPM1-Asp175Asn) genes. We studied the properties of HCM cardiomyocytes (CMs) derived from patient-specific human induced pluripotent stem cells (hiPSCs) carrying either

    Chapter 11 paper summary In this paper Regulation of Sarcolemmal Transport of Substrates in the Healthy and Diseased Heart written by Jan F. C. Glatz et al. they are discussing the role of long chain fatty acids or LCFA and glucose balances when it comes to healthy and diseased hearts. LCFAs and glucose are predominate for cardiac metabolic energy production meaning that these two substrates are the main energy providers when it comes to a healthy functioning heart.…

For every sample, two mice hearts were sacrificed and transferred to a flat-bottomed 2 mL centrifuge tube. The hearts were minced with surgical scissors after 500 µL isolation buffer (50 mL sucrose, 200 mM mannitol, 5 mM KH2PO4, 1 mM EGTA, 5 mM MOPS, 0.1% bovine serum albumin, pH to 7.3) was added to the tube (Sigma-Aldrich, St. Louis, MO, USA).…

    Gastrocnemius: A Muscle Tear

    In Thomsen's Disease, the cause is due to a mutation in the CLCN1 gene by autosomal dominant pattern (Myotonia congenita 2007). The CLCN1 gene regulates the flow of negatively charged chloride ions into and out of the muscle fibers (Myotonia congenita 2007). This is important in muscle contraction and relaxation (Myotonia congenita 2007). Therefore, when the CLCN1 gene is impaired, it cause myotonia (Myotonia congenita 2007). The levels of myotonia in Thomsen's Disease range from grade 1 to grade 3 (Colding-Jorgensen 2005).…

    Summary Of Peter's Dilated Cardiomyopathy

    Peter had Dilated Cardiomyopathy (DCM) resultant episodes of Ventricular Fibrillation (VF) and Ventricular Tachycardia (VT). Cardiomyopathy describes a family of heart diseases affecting the heart muscle resulting in structural and functional abnormalities. (NICOL BOOK). In DCM a portion of the myocardium in the ventricles is dilated leading to progressive cardiac enlargement and hypertrophy. (cite cardiac book) Peter had a familial history which was compounded by alcohol misuse which further depresses myocardium function.…

    Compare And Contrast Cardiovascular Hypertrophy

    Cardiovascular hypertrophy is the place the heart increases in size and blood volume, this is a direct result of typical exercise. This is valuable for contenders or people who hone much of the time in light of the way that they can continue with their level of movement and wellbeing. This is a positive since when cardiovascular hypertrophy happens more blood can be pumped around the body which infers greater imperativeness and oxygen can be transported around the body for use. When we rehearse the mass of the left ventricle thickens (chamber gauge extends) which fortifies the beat of the heart. This infers more blood can be pumped through the body; this is in light of the fact that the energy of the withdrawal is more grounded.…

    Hypertrophic Obstructive Cardiomyopathy

    I am often asked why I cannot have a cup of coffee following major heart surgery, which repaired a heart defect called Hypertrophic Obstructive Cardiomyopathy, or HOCM for short. I find that if I tell someone that I cannot have coffee, I am often met with disbelief, arguments on why I should have coffee, laughter, or even as far as waving a perfectly scented cup of lovely coffee under my nose. However, after everything I have been through concerning my heart, I will not succumb that easily to temptation. I have been told, "try decaf," Yet, I find that unless my Son (The Barista) makes it for me, decaf tastes like it was rinsed through cardboard, with the adage that it never gives you that perky feeling coffeeholics look for in the morning.…

    It is most commonly confused with hypertrophic cardiomyopathy (HCM). HCM is a disease of the heart where there's an abnormal wall thickness decreasing the size of the cavity and limiting the amount of blood it can hold and pump. It can occur with or without an obstruction. There are a couple ways of differentiating the two. LV cavity size in athletes is slightly bigger compare to HCM.…

    Embryonic Stem Cell Argumentative Essay

    Many people are opposed to embryonic stem cell research as it is necessary to terminate a living human embryo, which individuals like Pro life advocates think of as murder. There are two different types of stem cells we can encounter, embryonic stem cells and somatic stem cells also known as body cells. These cells are very important for living organisms as the embryo forms the structure for the foundation of the organism like muscle cells. Stem cells render a possibility for the treatment of diseases like heart diseases or macular degeneration. “Using adult stem cells drawn from bone marrow and umbilical cord blood stem cells, scientists have discovered new treatments for scores of diseases and conditions such as Parkinson's disease, juvenile diabetes, and spinal cord injuries.”…

    The Tell Tale Heart Insanity

    The narrator of the short story, “The Tell Tale Heart” by Edgar Allan Poe, is seen by the reader to be insane. This is assumed throughout the story and even at the very beginning due to the narrators over-use of persuasion towards the reader that he is not mad. The narrator is seen as being crazy or, more and more insane, as the story continues on. Evidence of this madness is shown in many different situations, and also is shown through the narrator’s thoughts during certain parts of the story. The narrator claims later in the story that there are reasons behind the actions that he decides to take.…

    The Morbidity Of Hear Heart Disease

    The heart is considered the “engine of life” through its ability to rhythmically pump oxygen rich blood throughout the body to supply life. Unfortunately, this vital organ is vulnerable to damage through actions of everyday life ranging from smoking, diet, physical inactivity, and consumption of alcohol. Damage to the heart results in heart disease, also known as cardiovascular disease. Because of the vast complexity of the heart, heart disease branches off into various categories including “Rheumatic heart disease, Hypertensive heart disease, Ischemic heart disease, Cerebrovascular disease, Inflammatory heart disease and Valvular heart disease” (World Heart Federation, 2016). These categories branch off even further to Angina, heart attacks, stroke and Arteriosclerosis (World Heart Federation, 2016).…

About 20% to 30% of people with a Congenital congenital heart defect have other physical problems or developmental or cognitive disorders, Children children with Congenital congenital heart defect are about 50% more likely to receive special education services compared to children without birth defects (Miller, Riehle-Colarusso, Alverson, Frias, Correa , 2011; Shillingford , et al., 2008; Limperopoulos , et al., 2000). Congenital heart anomalies are divided into levels of complexity: mild, moderate, and severe, more than half of with a critical type of congenital heart defect have…
