Causes: Dilated cardiomyopathy:
In most cases, the disease is idiopathic --a
specific cause for the damage is never identified. (Source: excerpt from NHLBI, Cardiomyopathy: NHLBI)

Dilated cardiomyopathy:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The cause of most cardiomyopathies is unknown. Occasionally, dilated cardiomyopathy results from myocardial destruction by toxic, infectious, or metabolic agents, such as certain viruses, endocrine and electrolyte disorders, and nutritional deficiencies. Other causes include muscle disorders (myasthenia gravis, progressive muscular dystrophy, and myotonic dystrophy), infiltrative disorders (hemochromatosis and amyloidosis), and sarcoidosis.
Cardiomyopathy may also be a complication of alcoholism. In such cases, it may improve with abstinence from alcohol but recurs when the patient resumes drinking. How viruses induce cardiomyopathy is unclear, but researchers suspect a link between viral myocarditis and subsequent dilated cardiomyopathy, especially after infection with poliovirus, coxsackievirus B, influenza virus, or human immunodeficiency virus.
Metabolic cardiomyopathies are related to endocrine and electrolyte disorders and nutritional deficiencies. Thus, dilated cardiomyopathy may develop in patients with hyperthyroidism, pheochromocytoma, beriberi (thiamine deficiency), or kwashiorkor (protein deficiency). Cardiomyopathy may also result from rheumatic fever, especially among children with myocarditis.
Antepartal or postpartal cardiomyopathy may develop during the last trimester or within months after delivery. Its cause is unknown, but it occurs most frequently in multiparous women older than age 30, particularly those with malnutrition or preeclampsia. In these patients, cardiomegaly and heart failure may reverse with treatment, allowing a subsequent normal pregnancy. If cardiomegaly persists despite treatment, the prognosis is poor.
Dilated cardiomyopathy occurs in 2 of every 100 people and affects all ages and sexes. It’s most common in adult men.

Hypertrophic cardiomyopathy:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Despite being designated as idiopathic, in almost all cases, hypertrophic cardiomyopathy may be inherited as a non–sex-linked autosomal dominant trait. Most patients have obstructive disease, resulting from effects of ventricular septal hypertrophy and the movement of the anterior mitral valve leaflet into the outflow tract during systole. Eventually, left ventricular dysfunction, from rigidity and decreased compliance, causes pump failure.
This disorder affects 2 to 5 of every 1,000 people.

Restrictive cardiomyopathy:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
An extremely rare disorder, primary restrictive cardiomyopathy is of unknown etiology. However, restrictive cardiomyopathy syndrome, a manifestation of amyloidosis, results from infiltration of amyloid into the intracellular spaces in the myocardium, endocardium, and subendocardium.
In both forms of restrictive cardiomyopathy, the myocardium becomes rigid, with poor distention during diastole, inhibiting complete ventricular filling, and fails to contract completely during systole, resulting in low cardiac output.
Restrictive cardiomyopathy is rare. It’s most common in children and young adults. Natives of Africa, South America, and India are at increased risk.

Clinical tip Dilated cardiomyopathy has a 50% mortality after 5 years; 50% of patients improve to normal within the first few months of delivery.

Cardiomyopathy, restrictive:
Causes
(Handbook of Diseases)
Primary restrictive cardiomyopathy is an extremely rare disorder of unknown cause. However, restrictive cardiomyopathy syndrome, a manifestation of amyloidosis, results from infiltration of amyloid into the intracellular spaces in the myocardium, endocardium, and subendocardium.
With both forms of restrictive cardiomyopathy, the myocardium becomes rigid, with poor distention during diastole, inhibiting complete ventricular filling. The myocardium also fails to contract completely during systole, resulting in low cardiac output.
UNDER STUDY: Researchers have identified a link between the sarcomere contractile protein gene and cardiac troponin I (TNNI3) — the gene that researchers believe causes restrictive cardiomyopathy when diseased. In genetic investigations, mutations of TNNI3 were identified in six of nine patients with restrictive cardiomyopathy. Investigations continue as to what this association means and its implications with restrctive cardiomyopathy.
