Doctor's Notes on Cardiomyopathy
Cardiomyopathy is when the heart muscle cannot contract or function normally that causes the heart to be weak and not able to pump blood adequately to the body. Signs and symptoms of cardiomyopathy may start with
- weakness and fatigue and exercise intolerance;
- shortness of breath and/or chest pain usually occurs as the heart muscle function decreases.
- Swelling of the feet, ankles, and legs frequently occurs.
- Some individuals may have electrical disturbances with cardiomyopathy; symptoms can be the same as above but can include palpitations, feelings of the heart skipping a beat or potentially fatal heart rhythms like ventricular fibrillation may happen.
Unfortunately, there are many causes of cardiomyopathy (at least 30, and many are due to other medical problems). However, any condition or disease that affects heart muscle so that it cannot supply the needed blood for the body’s demand can cause cardiomyopathy. A few examples that are common causes include
- genetic diseases,
- toxins like alcohol abuse or lead,
- hypertrophy (thickened ventricle),
- neuromuscular disorders, and
- many others.
What are the treatments for cardiomyopathy?
Cardiomyopathy is a general term that encompasses many types of problems. As stated above, there are 30 or more causes (types) of cardiomyopathy, too many to present in this summary. Consequently, this summary will present the general treatments used for this heart problem as treatments depend on the type of cardiomyopathy. They include:
- Medications to accomplish the following:
- Ablation therapy
- Septal ablation – the destruction of the thick obstructing heart muscle
- Radiofrequency ablation – radio waves that damage or kill abnormal heart cells that cause abnormal heart rhythms
- Surgery – procedures/devices
Your doctors and you can discuss what treatment protocols may be best for your cardiomyopathy type.

In the U.S., 1 in every 4 deaths is caused by heart disease.See Answer
Must Read Articles:
AlcoholismAlcohol problems vary in severity from mild to life-threatening and affect the individual, the person's family, and society in numerous adverse ways. Signs of a drinking problem include insomnia, loss of employment, blackouts, depression, auto accidents, bruises, frequent falls, and anxiety. Treatment involves stabilization, detoxification, and rehabilitation of the alcohol-dependent person.
Arrhythmias (Heart Rhythm Disorders)Arrhythmias or heart rhythm disorders are conditions that causes changes in the normal heartbeat. There are numerous types of arrhythmias, for example, supraventricular tachycardia, sinus sick syndrome, atrial fibrillation, atrial flutter, and ventricular fibrillation. Signs and symptoms of an arrhythmia may include: Chest pain or discomfort Shortness of breath Palpitations Racing heart sensation Treatment for arrhythmias depend upon the cause.
Atrial FlutterAtrial flutter is a type of arrhythmia, that is, an irregularity in the beating of the heart. Symptoms of atrial flutter include heart palpitations, shortness of breath, anxiety, weakness, and a fluttering feeling in the chest. Causes of atrial flutter include heart disease, hypertension, heart muscle disease, heart abnormalities, substances, and diseases that affect other areas of the body. Treatment of atrial flutter includes defibrillation and medication.
Chest PainChest pain has a variety of noncardiac and cardiac causes, some of which can be very serious. Signs and symptoms of chest pain may include burning, squeezing, or heaviness in the chest. Atherosclerosis, angina, lung tumors, chest trauma, abdominal pain, and gastric reflux are just a few potential causes of chest pain. Chest pain is diagnosed by taking the patient history and performing a physical exam. Blood work, imaging tests, and an exercise stress test may be ordered. The treatment and prognosis of chest pain depends on the underlying cause.
Cocaine Abuse (Addiction)Cocaine is one of the most commonly abused drugs in the U.S. Symptoms of cocaine abuse include dilated pupils, recurrent nosebleeds, and hallucinations. Medical professionals diagnose cocaine abuse by looking for signs and symptoms such as cocaine-induced headaches and cocaine-induced seizures; psychiatric complications like anxiety, hallucinations, and psychoses; nasal and throat complications like nosebleed and perforated nasal septum; pulmonary conditions like asthma and pneumonia; cardiovascular complications; and infectious complications.
Congestive Heart Failure (CHF)Congestive heart failure, or CHF, is a condition in which a person's heart is failing and it can't pump enough blood and oxygen to the body's tissues. Sometimes people with CHF don't know they have it. Early signs and symptoms symptoms are cough, shortness of breath, and having problems breathing; especially when lying down. And, if you have breathing problems like asthma, COPD, or emphysema and you think your condition is worsening. There are four stages of CHF. There's no cure for CHF, but treatments include drug therapy, diet, and lifestyle changes to relive symptoms and slow the progression of the disease. Life expectancy depends on existing medical problems, age, and overall health.
Electrocardiogram (ECG, EKG)An electrocardiogram (ECG, EKG) is a tool used to assist in diagnosing heart diseases and conditions, for example, atrial and ventricular fibrillation, heart attacks, and heart failure.
Heart AttackA heart attack is an interruption in blood flow to the heart muscle. Arterial plaque rupture is often the cause of a heart attack. Symptoms of a heart attack may include chest pain, shortness of breath, sweating, and nausea. Emergency heart catheterization and thrombolytic therapy may be used to treat a heart attack.
Heart DiseaseCoronary heart disease (CHD) is a group of different types of heart disease. Symptoms of heart disease depend on the cause and inclue chest pain or angina, shortness of breath, palpitations, and dizziness. Many conditions causes heart disease, for example, genetics, obesity, high cholesterol, and smoking. Treatment for heart disease depend on the cause and include diet and other lifestyle changes, medications, procedures, and surgery. The prognosis (outlook) and life span for someone with heart disease varies depending on the cause.
Is Takotsubo Cardiomyopathy a Heart Attack?Takotsubo cardiomyopathy is not a heart attack. Takotsubo cardiomyopathy, also called stress cardiomyopathy or "broken heart syndrome," is a heart condition that causes sudden and temporary chest pain, difficulty breathing, and lightheadedness and fainting. It commonly occurs in older women and may be triggered by intense emotional or physical stress such as the death of a loved one (this is why it’s sometimes called broken heart syndrome), an acute illness, or even a stressful argument.
Pulmonary EdemaPulmonary edema is a collection of excess fluid in the lungs. Pulmonary edema is classified as either cardiogenic (caused by heart problems) and non-cardiogenic. The primary symptom of pulmonary edema is shortness of breath. Pulmonary edema can be a life-threatening medical situation. The treatment for pulmonary edema can be ICU care in some cases, and medication in other cases.
Sudden Cardiac ArrestSudden cardiac arrest (SCA) usually causes death if it is not treated within minutes. Some of the causes of sudden cardiac death include ventricular fibrillation, medication or drug abuse/overdose, heart attack, physical stress, inherited disorders, and changes in the structure of the heart. Automatic external defibrillator (AED), if available is the best immediate treatment for sudden cardiac arrest.
What Is the Life Expectancy of Someone with Hypertrophic Cardiomyopathy?Hypertrophic cardiomyopathy is a heart defect characterized by the increased thickness (hypertrophy) of the wall of the left ventricle, the largest of the four chambers of the heart. It is chronic, genetic heart disease. Frequently, patients with hypertrophic cardiomyopathy have few to no symptoms or only symptoms with exercise or exertion.
