cardiomyopathy pathophysiology
The most common cause is coronary artery disease or heart attack.Hypertrophic cardiomyopathy can develop at any age, but the condition tends to be more severe if it becomes apparent during childhood.
The term \"cardiomyopathy\" is a general term that refers to the abnormality of the heart muscle itself.Dilated cardiomyopathy might not cause symptoms, but for some people it can be life-threatening. As cardiomyopathy worsens, the heart becomes weaker.

Inverted T waves are found in the limb and precordial leads, which is a common characteristic of takotsubo cardiomyopathy with apex balloon-like dilation.Systolic apex balloon-like dilation on left ventriculography (A) and normal diastolic dilation (B).
Treatment of cardiomyopathy is directed first toward identifying the underlying disease (e.g., hypothyroidism or hypertension).
All rights reserved. TCM is an important entity that differs from acute myocardial infarction.
In this chapter, we review our current understanding of the cardiomyopathies with a focus on the genetic mutations and molecular pathways implicated in their pathogenesis.
Despite our increased understanding of the molecular basis of the cardiomyopathies in the last 15 years, further research is critically necessary to develop novel therapeutic modalities for these morbid cardiovascular conditions.We use cookies to help provide and enhance our service and tailor content and ads.
While previously conceived as the general sequelae of ischemic heart disease or extrinsic insults, familial studies have greatly facilitated our understanding of the molecular basis for the cardiomyopathies.
Most affected people have a family history of the disease, and some genetic mutations have been linked to hypertrophic cardiomyopathy.Restrictive cardiomyopathy can occur for no known reason (idiopathic), or it can by caused by a disease elsewhere in the body that affects the heart, such as when iron builds up in the heart muscle (hemochromatosis).There are a number of factors that can increase your risk of cardiomyopathy, including:As your heart weakens, such as in heart failure, it begins to enlarge, forcing your heart to work harder to pump blood to the rest of your body.Cardiomyopathy can lead to other heart conditions, including:In many cases, you can't prevent cardiomyopathy.
Specific cases are usually categorized as dilated, hypertrophic, or restrictive, according to the observed abnormality.

Call 911 or your local emergency number if you have severe difficulty breathing, fainting or chest pain that lasts for more than a few minutes.Because some types of cardiomyopathy can be hereditary, if you have it your doctor might advise that your family members be checked.Often the cause of the cardiomyopathy is unknown.
Wall motion abnormality of the LV apex is generally transient and resolves within a few days to several weeks. In 1990, takotsubo cardiomyopathy (TCM) was first discovered and reported by a Japanese cardiovascular specialist. A: Systole; B: Diastole.The catecholamine theory of takotsubo cardiomyopathy. LV: Left ventricular. Dilated cardiomyopathy (DCM) is the most common type of cardiomyopathy. There might be no signs or symptoms in the early stages of cardiomyopathy. The ventricle stretches and thins (dilates) and can't pump blood as well as a healthy heart can. It has been suggested that coronary spasm, coronary microvascular dysfunction, catecholamine toxicity and myocarditis might contribute to the pathogenesis of TCM.

The hallmark pathophysiologic feature of dilated cardiomyopathy is systolic dysfunction. Cardiomyopathies are a heterogeneous group of disorders characterized by myocardial dysfunction that variably progress to a range of clinical symptoms including congestive heart failure, life-threatening arrhythmias, and sudden death. Histiocytoid cardiomyopathy Histiocytoid cardiomyopathy (or Purkinje cell hamartoma) is a rare cardiomyopathy that presents between birth and the age of four years and is more common in females. Name must be less than 100 characters Coronary artery disease is the leading cause of death with overall mortality of approximately 245 per 100 000 individuals in 2008.
