What is the difference between hypertrophic cardiomyopathy and cardiomyopathy

Federal Government. Read our disclaimer for details. Last Update Posted : December 8, Study Description. Detailed Description:. MedlinePlus related topics: Cardiomyopathy Heart Diseases. FDA Resources. After recruiting patients, collecting the baseline data, a CMR scan will be carried out and post-processed, a predetermined differentiating formula including left ventricular morphology, ejection fraction, presence of late gadolinium enhancement, T1 value and strain data will be used to produce a cardiac values, which is to be input into our differentiating flow.

The diagnosis of hypertensive heart disease was based on medical history and conventional echocardiography. The healthy age-matched controls were generally volunteers with a normal electrocardiogram, normal echocardiographic examination, and overall normal CMR findings. Outcome Measures. Primary Outcome Measures : validation of the algorithm in all patients [ Time Frame: after post-procession and complete the flow chart within 24 hours ] Evaluate the area under the curve of our algorithm compared with single parameter wall thickness, strain in all patients.

Eligibility Criteria. Information from the National Library of Medicine Choosing to participate in a study is an important personal decision. Consecutive subjects were prospectively enrolled into 3 cohorts between July and June The cohorts were divided as follows: the hypertrophic cardiomyopathy, hypertensive heart disease and control groups.

Contacts and Locations. This occurs most often in middle-aged people and more often in men than women, but has been diagnosed in people of all ages, including children. Most patients develop congestive heart failure. Dilated cardiomyopathy can be caused by chronic, excessive consumption of alcohol along with dietary deficiencies.

It occasionally occurs as a complication of pregnancy and childbirth. Other suggested causes are various infections mostly viral, which lead to an inflammation of the heart muscle, called myocarditis , toxins, and rarely heredity. Sometimes drugs used to treat a different medical condition can damage the heart and produce dilated cardiomyopathy. However, in most cases, a specific cause for the damage is never identified. Restrictive Cardiomyopathy Restrictive cardiomyopathy, the least common type of cardiomyopathy in the US, occurs when the myocardium of the ventricles becomes excessively rigid, and the filling of the ventricles with blood between heart beats is impaired.

It usually results from another disease which occurs elsewhere in the body. Restrictive cardiomyopathy does not appear to be inherited, but some of the diseases that lead to the condition are genetically transmitted. These genes cause the walls of the heart chamber left ventricle to contract harder and become thicker than normal. The thickened walls become stiff. This reduces the amount of blood taken in and pumped out to the body with each heartbeat.

In obstructive HCM, the wall septum between the two bottom chambers of the heart thickens. The walls of the pumping chamber can also become stiff. It may block or reduce the blood flow from the left ventricle to the aorta. Most people with HCM have this type.

This limits how much blood the ventricle can take in and pump out, but blood flow is not blocked. Others may not have signs or symptoms in the early stages of the disease but may develop them over time.

Knowing the signs and symptoms of HCM is important. It can help with getting an early diagnosis, when treatment may be most effective. Signs and symptoms of HCM include:. HCM is a chronic disease that can get worse over time.

This can lead to poorer function and quality of life, long-term complications and more financial and social burden. People with HCM often need to make lifestyle changes, such as limiting their activity, to adjust for their disease. As HCM progresses, it can cause other health problems. People with HCM are at higher risk for developing atrial fibrillation , which can lead to blood clots, stroke and other heart-related complications.

HCM may also lead to heart failure. It can also lead to sudden cardiac arrest , but this is rare. HCM has been cited as the most common reason for sudden cardiac death in young people and athletes under the age of Hypertrophic cardiomyopathy is most often inherited. HCM is the most common form of genetic heart disease. It can happen at any age, but most receive a diagnosis in middle age. A cardiologist or pediatric cardiologist often diagnoses and treats HCM.

You may also be referred to a cardiomyopathy center where the health care team has specialized training. HCM is diagnosed based on your medical history, family history, a physical exam and diagnostic test results.
