Hypertrophic cardiomyopathy (HCM) is an inherited structural cardiac disease which results in the hypertrophy of the myocytes in the cardiac myocardium. The non-obstructive variant of this cardiomyopathy results in uniform enlargement of the ventricles, rather than asymmetric enlargement of the septum only. Normal physiology of the heart defines cardiac output (CO) as a function of both heart rate and stroke volume. When the heart needs to increase CO to meet increased demands of the body, it can do so by either increasing the heart rate or the stroke volume. In HCM, however, the heart is unable to meet the need of increased CO by increasing stroke volume because of structural limitations, so the heart has to primarily rely on increasing the heart rate to raise CO. Unfortunately, in a HCM heart, tachycardia will not help increase cardiac output either, since the amount of filling time during diastole decreases as the heart rate increases which only exacerbates the problem of a reduced LVEDV. Despite this limitation, many patients with HCM are asymptomatic until the body is stressed to the point that the heart is no longer able to compensate, at which point they will develop symptoms. Since HCM is an inherited disease, and patients don’t necessarily know they have it until they are symptomatic, this is a disease which is increasingly screened for in high school athletes because of the high risk for sudden cardiac death (SCD) from unknown HCM.
Characteristic Signs and Symptoms
The characteristic signs and symptoms of HCM reflect the inability of the heart to effectively fill during diastole and mimic the symptoms of heart failure or valvular disease. The reduced LVEDV results in an inadequate cardiac output to meet the oxygen dema...

...cker therapy, even if asymptomatic, as an attempt to prevent severe pressure gradients which could lead to SCD. However, if concern for SCD is strong, the prevailing recommendation is for ICD placement.
Non-Pharmacologic Treatments
In patients that are considered at high risk of developing fatal ventricular arrhythmias, an implanted cardioverter-defibrillator (ICD) may be recommended to reduce the risk of SCD. The function of an ICD in patients with HCM is to prevent SCD by terminating fatal ventricular arrhythmias. This is either done as primary prevention, for patients at high risk for SCD, or secondary prevention, for patients with documented tachy-arrhythmias or a past episode of SCD. Interventions used for HOCM, the obstructive variety of HCM, such as ethanol ablations or myectomies, are not routinely offered for patients with the non-obstructive form of HCM.

Symptoms and Dignosis of Hypertrophic Cardiomyopathy Essay

- Hypertrophic Cardiomyopathy (HCM), big word and sounds scary, but it isn’t as scary as you might think. This disease affects the myocardium (middle layer of the heart that helps it contract) by becoming abnormally thick and this doesn’t allow the heart to pump normally. Some people go undiagnosed for quite some time since there are little to no symptoms, some however have shortness of breath. HCM also affects the electrical system In the heart which can cause life threatening arrhythmia (irregular heartbeat)....   [tags: myocardium, heart, death]

Cardiomyopathy : A Disease Of The Heat Muscle Essay

- Cardiomyopathy is a disease of the heat muscle and has many different types. Dilated, Hypertrophic, and Restrictive are the three main types of cardiomyopathy. Each of these types have different causes, signs and symptoms, and treatments. In cardiomyopathy, the heart muscle can become enlarge, thick, or rigid, and in some rare incidents the muscle tissue can become replaced with scar tissue. As the condition worsens, the heart becomes weaker and less able to pump blood throughout the body. The heart will also become unable to maintain a normal electrical rhythm....   [tags: Heart, Cardiology, Blood, Cardiomyopathy]

Cardiomyopathy : Symptoms And Treatment Essay

- Cardiomyopathy, by definition, means the weakening of the heart muscle. The heart is operated by a striated muscle that relies on the autonomic nervous system to function. Cardiomyopathy is diagnosed in four different ways based on what caused the illness and exactly what part of the heart is weakened. The four main types of cardiomyopathy are dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, and arrhythmogenic right ventricular dysplasia. One other category of cardiomyopathy that is diagnosed is “unclassified cardiomyopathy.” Unclassified cardiomyopathy is the weakening of the heart that does not fit into the main four categories....   [tags: Heart, Cardiology, Myocardial infarction, Blood]

Symptoms And Outcomes Of Cardiomyopathy Essay

- WHAT IS A CARDIOMYOPATHY. Cardiomyopathy is a disease of the heart muscle, causing the heart muscle to become enlarged, thick or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue. As cardiomyopathy worsens, the heart becomes weaker. It 's less able to pump blood through the body and maintain a normal electrical rhythm. This can lead to heart failure and rhythm problems. In turn, heart failure can cause fluid to build up in the lungs, ankles, feet, legs or abdomen....   [tags: Cardiomyopathy, Heart, Hypertrophic cardiomyopathy]

- Therapeutic Approaches to Hypertrophic Cardiomyopathy   Therapeutic Approaches to Hypertrophic Cardiomyopathy Hypertrophic Cardiomyopathy is a widely studied and common genetic heart disease which has many therapeutic treatments. This is a genetic disease that is caused by mutations of the sarcomeres in the cells that make up the tissue of the heart (B. Maron et al., 2003, p. 1690). It usually affects the left ventricle of the heart which is responsible for sending, or pumping, blood to the entire body (Nishimura, Ommen, & Tajik, 2003, p....   [tags: genetic disease, family history, blood]

Overivew of Cardiomyopathy Essay

- Introduction: Heart disease is the highest reported cause of death in the United States. The Center for Disease Control and Prevention (2012), reported that heart disease accounted for nearly 600,000 deaths, even trumping cancer by approximately 25,000. Health conditions that severely damage or weaken the heart can lead to heart failure (Mayo Clinic, 2013). Cardiomyopathy is heart disease that targets the myocardium, causing it to enlarge, thicken or become rigid. The National Heart, Lung, and Blood Institute characterizes cardiomyopathy into to four different types: dilated, hypertrophic, restrictive, and arrhythmogenic....   [tags: Heart Disease, Medical]

Left Ventricular Systolic Dysfunction Essay

- Left Ventricular Systolic Dysfunction (LVSD, but commonly referred to as heart failure) is a chronic, progressive cardiac syndrome in which a damaged heart fails to beat efficiently and deliver enough blood to meet the body's needs. Although coronary heart disease (CHD) is the most common cause, for example, myocardial infarction, and many of the conditions are intertwined, there are several other causes of heart failure including cardiomyopathies, hypertension and valve disease. Cardiomyopathies can be caused by genetic disorders/defects, viral illness, some endocrine conditions, autoimmune diseases, and excessive use of alcohol and drugs....   [tags: Health]
