Cardiomyopathy – Causes, Symptoms Treatment

Cardiomyopathy (including PPC and alcoholic cardiomyopathy), which is the expansion or enlargement ventricles of the heart and heart size increased in general. This condition can be caused by heart diseases, viruses, abuse of drugs illicit alcohol, and genetic disorders. In addition, idiopathic dilated cardiomyopathy (dilated cardiomyopathy also known unknown cause) is not uncommon. Dilated cardiomyopathy causes about 10,000 deaths annually in the United States and is one of the main causes of heart transplantation.

Cardiomyopathy refers to diseases of the heart muscle. These diseases enlarge your heart muscle or make it thicker and stiffer than normal. In rare cases, scar tissue replaces the muscle tissue. Some people live a long and healthy life with cardiomyopathy. Some people do not realize they have it. In others, however, can cause the heart can pump blood through the body. Cardiomyopathy is a disease of the heart muscle. There are three main types of cardiomyopathy – dilated, hypertrophic and restrictive – that affect the heart muscle, often making it difficult to pump blood and give the rest of his body. There are many causes of cardiomyopathy, including diseases coronary and valvular heart disease.
Causes

Approximately 20-30% of cases of dilated cardiomyopathy has been reported that family, but with a incomplete penetrance and age-dependent, and linked to a more diverse group of 20 loci and genes. Although genetically heterogeneous, the predominant mode of transmission for dilated cardiomyopathy is autosomal dominant, X-linked, autosomal recessive, and mitochondrial less frequent.

Cardiomyopathy can be caused by viral infections, heart attacks, alcoholism, hypertension, long-term high pressure, nutritional deficiencies (particularly selenium, thiamine and L-carnitine), systemic lupus erythematosus, celiac disease and ESRD.

The most common cause of cardiomyopathy in developed countries is coronary artery disease. Heart attacks kill heart muscle by obstruction of a coronary artery. While the damage is located in the region of muscle supplied by that artery, in a few months while the dilated left ventricle (or renovation) to compensate for the damage. With a mild heart attack, the amount of ventricular dilatation is minimal.

Symptoms

Symptoms of cardiomyopathy include shortness of breath on exertion, dizziness, fainting and angina pectoris. (Angina is chest pain or discomfort caused by reduced blood supply to the heart muscle.) Some people have cardiac arrhythmias. They are abnormal heart rhythms in some cases can lead to sudden death. Often, an implantable cardioverter defibrillator (ICD) is required to shock the heart to restart a normal heart rhythm and prevent the coup settled. The obstruction of blood flow from the left ventricle increases the ventricle's work, and a heart murmur can be heard.

Treatment

Antiarrhythmics may be given to prevent abnormal heart rhythms. Most of these drugs prescribed in small doses. The dose was increased by small increments, because if the dose is too large, an anti-arrhythmic disorders may worsen or rhythm reduce cardiac pumping function. Some people have an abnormality of the heart's electrical conduction, which can be helped by a pacemaker. Doctors may consider an implantable pacemaker-defibrillator in patients with persistently poor cardiac function and increased risk of sudden death.

Is it hard to diagnose angina?

I have a friend and her doctors are not sure, but they believe that their angina chest. Is it possible they are wrong? Is angina angina pectoris a heart problem that is not easy to diagnose? Symptoms are unclear or too broad to be safe? Even after numerous tests (ie ECG, stress testing, the heart of the analysis, etc.)?

It may be a misdiagnosis, but unlikely. The main symptom is chest pain on exercise or stress
