Cardiomyopathy, or heart muscle disease, is a type of progressive heart disease in which the heart is abnormally enlarged, thickened, and/or stiffened. As a result, the heart muscle's ability to pump blood is less efficient, often causing heart failure and the backup of blood into the lungs or rest of the body. The disease can also cause abnormal heart rhythms.
2. CARDIOMYOPATHY
Cardiomyopathy is a disease of the heart
muscle that makes it harder for your heart to
pump blood to the rest of your body
Or
Cardiomyopathy is a group of diseases that
affect the heart muscle.
3. INCIDENCE:
Dilated cardiomyopathy, the most common form,affects 5% in
100,000 adults and 0.57% in 100,000 children.
Hypertrophic cardiomyopathy, the leading cause of sudden death in
athletes, with an incidence of one in 500 persons.
Restrictive cardiomyopathy and arrhythmogenic right ventricular
cardiomyopathy are rare, and their noses require a high index of
suspicion.
4. Risk factors:
MODIFIABLE RISK FACTORS:
• Tobacco use
• High blood cholesterol or triglyceride levels
• Lack of exercise
• Obesity
• Stress
NONMODIFIABLE RISK FACTORS:
• Family history of heart disease
• Older age
• Diabetes
• High blood pressure
7. Dilated Cardiomyopathy (DCM)
• This is the most common type of
cardiomyopathy.
• In this disorder, the left ventricle becomes
enlarged (dilated) and can't effectively
pump blood as the pumping ability of
heart's main pumping chamber (left
ventricle) becomes less forceful.
9. Hypertrophic Cardiomyopathy:
This type involves abnormal thickening of
your heart muscle, particularly affecting the
muscle of your heart's main pumping chamber
(left ventricle).
10. Restrictive Cardiomyopathy
The heart muscle in people with restrictive
cardiomyopathy becomes rigid and less elastic,
meaning the heart can't properly expand and fill
with blood between heartbeats.
11. ARRHYTHMOGENIC RT-VENTRICULARDYSPLASIA
In this type of cardiomyopathy, the muscle in
the lower right heart chamber (right ventricle)
is replaced by scar tissue. This can lead to
heart rhythm problems.
12. Symptoms:
• Breathlessness
• Swelling of the legs, ankles and feet
• Bloating of the abdomen due to fluid buildup
• Cough while lying down
• Fatigue
• Irregular heartbeats
• Chest pain
• Dizziness
19. Conti..
• Heart Transplant - A heart transplant is a last resort treatment for people
who have end-stage of heart failure.
20.
21. NURSING DIAGNOSIS:
• Impaired gas exchange related to decreased blood flow as evidenced
by breathlessness
• Acute pain related to disease condition as evidenced by patient
verbalization
• Impaired physical mobility related to weakness as evidenced by
patient is unable to perform daily activity.
• Imbalanced nutrition less than body requirement related to less intake
of food as evidenced by weight loss.
22. RESEARCH STUDY:
A study was conducted by European National health care database
reviled that many commonly used non steroidal anti-inflammatory drugs
are associated with 19% elevated risk for hospital admission for heart
failure. The risk for heart failure doubled for NSAIDs used at twice or
more the recommended daily allowable dose.
24. CONCLUSION:
The scientists discovered genes which increase the risk of dilated
cardiomyopathy, an inherited myocardial insufficiency that can lead to
heart failure and sudden death. During herat transplants, the scientists
collected biopsies from the left ventricle of 97 patients with DCM and
108 healthy donors. They analysed the transcriptome and managed to
identify 228 genes which are expressed differently in DCM patients
and heathy subjects.
