The 3 main types of cardiomyopathy are:
heart muscle dilates
Ventricular chamber size
the heart becomes weaker heart failure
can also lead to heart valve problems (regurgitation),
arrhythmias, and blood clots in the heart (poor blood flow),
a common reason for needing a heart transplant.
diabetes and thyroid disease
occurs when the heart muscle thickens abnormally (left ventricle)
1.) obstructive type
2.) non-obstructive type
Left ventricular hypertrophy
ventricular chamber size
pressure in the ventricles and lungs
changes in the cardiac muscles interfere with the heart's electrical signals sudden cardiac arrest
develop over time
often, the cause is unknown.
the ventricles become stiff and rigid due to replacement of the
normal heart muscle with abnormal tissue.
radiation treatments,infections or scarring after surgery
Having a family history
Having a disease or condition that can lead to cardiomyopathy
Diseases that can damage the heart
Long-term high blood pressure
Diabetes and other metabolic diseases
some have no symptoms in the early stages of the disease
as cardiomyopathy progresses and the heart weakens, signs and
symptoms of heart failure usually appear.
These signs and symptoms include:
Shortness of breath after exercise or even at rest
Swelling of the abdomen, legs, ankles, and feet
Other signs and symptoms: dizziness, lightheadedness, fainting during exercise, abnormal heart rhythms, murmurs
The main goals of treating cardiomyopathy are to:
Manage conditions that cause to the cardiomyopathy
Control symptoms so that the person can live as normally as possible
Stop the disease from getting worse
Reduce complications and the chance of sudden cardiac death
Angiotensin-converting enzyme (ACE) inhibitors
Calcium channel blockers
- also called septal myomectomy
- is open-heart surgery for hypertrophic obstructive
Surgical implanted devices
- a left ventricular assist device (LVAD)
-an implantable cardiverter defibrillator (ICD)
Losing excess weight
Eating a low-salt diet
Getting moderate exercise, such as walking, and avoiding strenuous exercise
Avoiding the use of alcohol and illegal drugs
Getting enough sleep and rest
Treating underlying conditions, such as diabetes and high blood pressure
90% of heart transplants are performed on patients with end-stage
88 % of patients survive the first year after transplant
72 % survive for 5 years
50 % survive for 10 yrs.
16 % survive 20 years.
Poor blood circulation
Diseases of the kidney, lungs, or liver
History of cancer
Inability or unwillingness to follow lifelong medical instructions
after a transplant.
Pulmonary arterial hypertension
Organs are matched for blood type and size of donor and recipient.
The Donor Heart
Guidelines on how a donor heart is selected :
the donor meet the legal requirement for brain death
consent forms are signed
younger than 65 years of age
have little or no history of heart disease or trauma to the chest
not exposed to hepatitis or HIV
donor heart must be transplanted w/in 4 hrs. after removal from
Immunosuppressants used: cyclosporine, tacrolimus, MMF (mycophenolate mofetil), and steroids such as prednisone.
Watching for Signs of Rejection
Shortness of breath
Reduced amounts of urine
Failure of the donor heart
Primary Graft Dysfunction
Rejection of the Donor Heart
Cardiac Allograft Vasculopathy
Complications from medicines
Cancer – lymphoma and skin cancer (due to suppression of the
