Hypertrophic Cardiomyopathy



Hypertrophic cardiomyopathy (HC) is a condition in which there is increased cardiac muscle. This hypertrophy hinders the outflow of blood from the heart by forcing it to work harder to pump blood.
Treatment
The goal of treatment is to control symptoms and prevent complications. It is possible that some patients need to stay in hospital until the condition is under control (stabilized).
If you have symptoms, you may need a medication to help the heart to contract and relax properly. Some drugs used include beta blockers and calcium channel blockers, which can reduce chest pain and other symptoms, particularly with exercise. The medications often relieve symptoms so that patients do not need more invasive treatments.
Some people with arrhythmias may require antiarrhythmic drugs. If the arrhythmia is due to atrial fibrillation, anticoagulants can also be used to reduce the risk of blood clots.
Some patients may have a permanent pacemaker placed. However, pacemakers are used less today than before.
When blood flow out of the heart is severely blocked, can be made an operation called surgical myectomy. This procedure cuts and removes a portion of the hypertrophied heart. Patients who undergo this procedure often show significant improvement. If mitral heart valve is leaking can be made surgery to repair or replace the valve.
In some cases, patients may receive an injection of alcohol into the arteries that nourish the heart hypertrophied part (septal ablation alcohol) causing a heart attack essentially controlled.
An implantable cardioverter-defibrillator (ICD) may need to prevent sudden death. The ICDs are used in patients at high-risk. High-risk situations include:
• Fall in blood pressure during exercise
• Family history of cardiac arrest
• History of cardiac arrest or ventricular tachycardia
• History of unexplained fainting
• Rhythms with cardiac death risk in a Holter monitor
• severe hypertrophy of cardiac muscle
Prevention
If you are diagnosed with hypertrophic cardiomyopathy, your doctor may recommend that your close blood relatives (family members) to undergo screening for the condition.
Some patients with mild forms of hypertrophic cardiomyopathy are only diagnosed by screening echocardiograms because of their known family history.
If you have high blood pressure, make sure you take your medication and follow the doctor's recommendations.
DIAGNOSIS AND TREATMENT
DIAGNOSIS:

History and physical examination by a physician.
Blood tests. Electrocardiography.
Techniques static and dynamic exposure, such as:
Cardiac ultrasound, sometimes through the esophagus.
Cardiac catheterization.
X-ray of the heart, lungs and blood flow (angiography).
TREATMENT:
The treatment is based on:
The medical treatment.
Hospitalization.
Either open surgery to replace defective valves (sometimes).
General measures
Note to any doctor, dentist or anesthetist that you are going to try to have a heart valve condition.
Remember, even though you think you know the details of your medical history.
Medication
Your doctor may prescribe:
Antibiotics to treat or prevent infection of the heart valves.
Antiarrhythmic drugs to combat irregularities of heart rhythm.
Medication with digitalis to strengthen or stabilize the heart rhythm.
Diuretics to reduce cardiac overload.
Activity
All you can tolerate.
With certain types of heart valve disease are unnecessary restrictions.
Diet
Low fat and salt.
Tell your doctor if
Signs of infection such as:
fever,
chills,
muscle aches,
headache
fatigue and malaise.
He has a sudden worsening of symptoms.
PREVENTION
Seek medical treatment for diseases that cause lesions in heart valves, such as hypertension, endocarditis, and syphilis.
Strep antibiotics for infections to prevent rheumatic fever.
If you have a family history of congenital heart disease, seek genetic counseling before having children.
