- Autoimmune illnesses
- Conditions that run in families
- Infections that involve the heart muscle
What is the prognosis for cardiomyopathy?
PPCM is treatable and in most cases, the heart functions normally after. It's important to diagnose it early. "So all forms of cardiomyopathy, if diagnosed early enough, we can get them on excellent medical regimens and many times the heart becomes normal again," said Dr. Howard.
What is nonischemic cardiomyopathy?
Dilated cardiomyopathy, also sometimes referred to as dilated, non-ischemic cardiomyopathy, is a type of heart muscle disease that causes the left ventricle of the heart to stretch abnormally. This prevents your heart from pumping blood effectively.

What is the best medicine for heart problems?
Beta-blockers (atenolol, metoprolol, carvedilol, etc) can relax the heart, lower blood pressure and slow the heart to improve filling and pumping function. Medications classified as ACE-inhibitors (lisinopril, enalapril, etc) or ARB’s (losartan, candesartan, etc) can also lower blood pressure, relax the heart and improved blood flow to the kidney.
What is nonischemic cardiomyopathy?
The term nonischemic cardiomyopathy ( NICM) encompasses a spectrum of diseases, including dilated idiopathic cardiomyopathy, cardiac sarcoidosis, and other forms of myocarditis as well as Chagas disease , hypertrophic cardiomyopathy, amyloidosis, valvular heart disease, and arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D). Most of these disease entities result in myocardial scar formation, thus creating a substrate for the subsequent development of ventricular arrhythmias. Ventricular tachycardias are among the many clinical manifestations of disease in patients with NICM. This chapter focuses on ventricular tachycardia (VT) ablation in patients with idiopathic dilated cardiomyopathy, myocarditis, cardiac sarcoidosis, ARVC/D, hypertrophic cardiomyopathy, and Chagas disease.
What is the treatment for dilated cardiomyopathy?
As with nonischemic cardiomyopathy, therapy for dilated cardiomyopathy that is associated with HIV infection includes diuretics, digoxin, aldosterone antagonists, beta blockers, and angiotensin-converting enzyme inhibitors.
Is NICM heterogeneous or heterogeneous?
NICM is very heterogeneous, and MRI may establish the diagnosis or allow for scar identification and localization. Scar location is highly predictive of abnormal potentials. In a heterogeneous group of cardiomyopathies, most of the clinical studies targeted the failure of the endocardial approach and found a 100% rate of low-voltage areas or abnormal electrogram (EGM) in the epicardium. 34 Nakahara et al. found a 100% epicardial substrate rate in seven patients with previous ablation failure. 27 The common location of scars in this condition is the basolateral and inferolateral LV ( Fig. 128.4 ).
Is NICM a viral disease?
Nonischemic Cardiomyopathy (NICM) The pathogenesis of NICM with ventricular dilatation and reduced cardiac function in the absence of flow-limiting coronary artery disease (CAD) can be genetic, inflammatory, toxic, or viral. However, in the vast majority of cases, the origin is unclear.
Is nonischemic cardiomyopathy heterogeneous?
Nonischemic Cardiomyopathy. Nonischemic cardiomyopathies are a heterogenous group of disorders, including idiopathic dilated cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy, that have been shown highly associated with SCD and ventricular arrhythmias. From: Cardiac Electrophysiology Clinics, 2019. Download as PDF.
Is NICM genetic or viral?
The pathogenesis of NICM with ventricular dilatation and reduced cardiac function in the absence of flow-limiting coronary artery disease (CAD) can be genetic , inflammatory, toxic, or viral. However, in the vast majority of cases, the origin is unclear. While syncope and sudden death are rarely the initial manifestations of the disease, NICM is often associated with VT. Cardiac MRI readily assesses the anatomical and functional abnormalities related to NICM. LGE using gadolinium contrast can be used to identify scar in the evaluation of patients with NICM. Although absence of LGE is the most common finding in NICM, midwall striae or patches of enhancement can be identified in up to 42% of cases. 25 Compared to ICM, the pattern and location of delayed enhancement in NICM is often atypical, making it difficult to distinguish artifact from true scar ( Fig. 63.2 ). The presence of scar should therefore be verified using multiple planes. Utilizing CMR to delineate scar distribution, we showed that the VT substrate in NICM is a midwall scar involving greater than 25% of the wall thickness. 26 In a prospective study of patients with NICM, Assomull and colleagues demonstrated that this high-risk midwall fibrosis pattern predicts sudden cardiac death (SCD) and spontaneous VT. 27 In patients with newly diagnosed NICM, the extent of myocardial scar, as quantified by LGE, is independently associated with lack of response to medical therapy, as well as with the combined endpoint of mortality and hospitalizations. 28 The transmural extent of LGE predicts inducibility of VT at the time of electrophysiology study and the composite endpoint of hospitalization for heart failure, appropriate ICD firing, and cardiac death. 25
What is cardiomyopathy?

It can occur in people of all ages, races or genders, and it is a frequent cause of sudden cardiac arrest and sudden cardiac death. For [...]
Why do clots form in the heart?
Blood clots. Because your heart can't pump effectively, blood clots might form in your heart. If clots enter your bloodstream, they can block the blood flow to other organs, including your heart and brain. Heart valve problems. Because cardiomyopathy causes the heart to enlarge, the heart valves might not close properly.
What causes a heart attack?
The most common cause is coronary artery disease or heart attack. However, it can also be caused by genetic defects. Hypertrophic cardiomyopathy. This type involves abnormal thickening of your heart muscle, which makes it harder for the heart to work.
What happens when your heart is weak?
As your heart weakens, such as in heart failure, it begins to enlarge, which forces your heart to work harder to pump blood to the rest of your body. Cardiomyopathy can lead to serious complications, including: Heart failure. Your heart can't pump enough blood to meet your body's needs.
What is the name of the condition where the muscle in the right ventricle is replaced by scar tissue?

What are the prognostic factors for non-ischemic cardiomyopathy?
The high blood pressure and tachycardia and edema are the prognostic factors regarding non-ischemic cardiomyopathy. Along with this the pulmonary hypertension and dysfunction of left ventricular are also the prognostic factors reported. These factors always vary with the severity and genetics of disease.
What are the causes of increasing mortality?
The mortality rate and morbidity rate is increasing day by day due to two main causes reported which are arrhythmia and cardiac failure. The main cause reported behind cardiac failure is the ischemic or non-ischemic cardiomyopathy. The mortality rate reported is 3 to 5 % in adults and 6 % in children per year.
How long does a non-ischemic cardiomyopath live?
A recent study showed that about 50 % of patients having non-ischemic cardiomyopath die within 2 years of diagnosis. The diagnosis if put forward the disease at early stage, then the life expectancy is increased because of treatment started at early stage of disease. Study also shows that there is 12 % chance of death of every patient with non-ischemic cardiomyopathy within a year after diagnosing because it is the most critical time period regarding treatment.
Is heart failure a progressive disease?
In this condition, the heart is not able to pump the blood properly and also could not fill the heart with blood. This disease is not a result of reduced blood pressure as in ischemic cardiomyopathy. This condition can be prove fatal for the patient in form of heart failure. It is a progressive disease.
What are the two categories of cardiomyopathy?
Healthcare professionals may categorize cardiomyopathy based on the general cause. These two categories are: Ischemic cardiomyopathy, caused by heart attacks or coronary artery disease (CAD). Non-ischemic cardiomyopathy, types unrelated to CAD. Sometimes, experts don't know the cause of cardiomyopathy (idiopathic).
How many people have cardiomyopathy?
About 1 in 500 adults have cardiomyopathy. Some types of cardiomyopathy are more likely in some people than in others. For example, dilated cardiomyopathy is more common in Black people. Dilated and arrhythmogenic cardiomyopathy are more likely in males.
How can cardiomyopathy improve your life?

Endocrine conditions, such as diabetes or thyroid disease. Family history of heart failure, cardiomyopathy or sudden cardiac arrest. Previous heart attacks.
What is the term for the condition where the heart is weak?
Cardiomyopathy refers to conditions that affect the myocardium (heart muscle). Cardiomyopathy can make your heart stiffen, enlarged or thickened and can cause scar tissue. As a result, your heart can’t pump blood effectively to the rest of your body. In time, your heart can weaken and cardiomyopathy can lead to heart failure.
Can cardiomyopathy be treated?
Others develop from underlying conditions such as coronary artery disease. Treatment for cardiomyopathy may include medications, lifestyle changes or surgery. Although there is no cure for cardiomyopathy, you can manage the condition. People who receive treatment can live a high quality of life with cardiomyopathy.
Can cardiomyopathy affect children?
Pediatric cardiomyopathy can affect children and teenagers of any gender, race or age. It is more likely to develop in infants than in older children. Children may inherit cardiomyopathy. More rarely, they may develop cardiomyopathy from a viral infection.
Why does cardiomyopathy decrease blood flow?
In dilated cardiomyopathy, the heart's ability to pump blood is decreased because the heart's main pumping chamber, the left ventricle, is enlarged, dilated and weak. At first, the chambers of the heart respond by stretching to hold more blood to pump through the body. This helps to strengthen the heart's contraction and keep ...
What is a family history of idiopathic DCM?
Women after childbirth (peripartum cardiomyopathy). When there is no known cause, the condition is called idiopathic dilated cardiomyopathy. About 1/3 of patients with idiopathic DCM have a family history, called familial dilated cardiomyopathy ( ref ). Familial DCM is a genetic condition.
What is the purpose of a myocardial biopsy?
Occasionally, a myocardial biopsy may be performed to determine the cause of cardiomyopathy. During a myocardial biopsy, small tissue samples are taken from the heart and examined under a microscope to determine the cause of the cardiomyopathy. Family members with familial idiopathic DCM should be screened for DCM.
What causes a viral infection?
Sometimes a viral illness may be responsible. Occasionally it may be inherited (familial cardiomyopathy) Heart valve disease (valvular cardiomyopathy) Alcoholism (heavy drinking, alcoholic cardiomyopathy) Drug abuse or taking d rugs that are toxic to the heart. Thyroid disease. Diabetes.
What is CRT in cardiology?
Cardiac Resynchronization Therapy (CRT, such as biventricular pacing) : In some patients with advanced heart failure, biventricular pacing (a pacemaker that senses and initiates heartbeats in the right and left ventricle) improves survival, reduces symptoms and increases exercise capacity or tolerance. For people with heart block or some bradycardias (slow heart rates), this pacemaker will also serve to maintain an adequate heart rate.
