Heart Condition called Hypertrophic Cardiomyopathy
This is a condition in which the muscle of the heart (myocardium) is thickened. However, the thickening is referred to as hypertrophic and can only affect a portion of the heart muscle (myocardium); or almost all of the muscle.
The cardiac contractile cells (myocytes) in the heart increase in size without any particular cause; and eventually lead to the thickening of the muscle. Also the normal alignment of the heart muscle cells is affected; as well as the functions of electrons in the heart.
Furthermore, the portion most commonly affected by this abnormal thickening is at the septum between the heart ventricles; below the aortic valve.
This condition causes rigidity to occur to the wall as of the heart; and also abnormal aortic and mitral valve function; both of which may limit the normal flow of blood out of the heart. Meanwhile, this can highly result to heart failure or cardiac arrest.
Signs and symptoms of HCM heart condition
Moreover, HCM is usually asymptomatic. i.e. its not easy to see/detect any symptom on a patient. This results to a person with the condition living a normal lifel only to die a sudden death as a result of heart failure.
Sometimes, a person suffering from the condition may develop symptoms; which continue to progress and become more elaborate as the condition worsens with time.
The symptoms include:
Dyspnea (shortness of breath)
Nonetheless, this is the most common symptom; occurring in as many as 90% of symptomatic patients. Dyspnea results due to the elevation of left ventricle diastolic filling pressures; (as well as transmission of those elevated pressures back into the pulmonary circulation). However, the elevated left ventricle filling pressures are caused by impaired diastolic compliance; due the thickening of the ventricle.
Symptoms of angina are common in HCM patients. They may occur in the absence of detectable coronary atherosclerosis. Impaired diastolic relaxation and markedly increased myocardial oxygen consumption are caused by ventricular hypertrophy that results in subendocardial ischemia.
Syncope and Presyncope
Syncope can either result due to the failure of cardiac output. It is common in children and young adults. Simply because they have small left ventricle chamber size. This can be evidenced by ventricular tachycardia upon ambulatory monitoring.
Syncope can also result from cardiac arrhythmia; either tachycardias or bradycardias. Several patients with HCM have abnormalities in sinus node function; leading to sick sinus syndrome with alternating tachyarrhythmias and bradyarrhythmias or severe bradyarrhythmias.
Syncope and presyncope identify patients at high risk of sudden death; and warrant an urgent workup and aggressive treatment.
As a matter of fact, this is usually easily detectable and severe after a vigorous activity; after rest or after having a meal.
This is characterized by abnormal and hard heart pulse rhythms; which cause the chest to be heavy and experience mild pain.
Palpitations results from arrhythmias; such as premature atrial and ventricular beats. Along with sinus pauses, atrial fibrillation, atrial flutter, supraventricular tachycardia, as well as ventricular tachycardia.
Nevertheless, this can be caused by the abnormal heart rhythms; which results to poor blood flow.
Due to cardiac arrest.
Body fatigue and general weakness
- HCM is genetically and can run down family lines.
- HCM is also caused by High blood pressure although this is a rare occurrence.
- It can also occur with age.
- HCM is diagnosed through a physical exam.
- A patient can be diagnosed through medical history if the condition runs down a family line.
- Echocardiogram test on also be used together with chest x-ray, CT scan, MRI and catherization to diagnose the condition.
