hypertrophic cardiomyopathy

A common (1:500) condition which causes a range of mild to severe clinical and pathologic changes, which are either symmetrical (concentric) or asymmetrical (eccentric hypertrophy), with disproportionate thickening beneath the mitral valve, seen without other cardiac disease. Half are congenital with autosomal dominant patterns of inheritance—e.g., MIM 192600, MIM 160760. Obstruction is associated with reduced venous return.

Clinical findings, young patients
Range from asymptomatic to diastolic dysfunction, dyspnea, fatigue, anginal pain, syncope, an increased risk of severe obstruction, congestive heart failure, sudden death simulating acute myocardial infarction.

Clinical findings, older patients
Shortness of breath, anginal pain, syncope.

EKG Increased
QRS complexes, T-wave inversion, Q waves in inferior and left-precordial leads—which translate into asymmetric hypertrophy of the septum (usually of left side), systolic anterior movement of mitral valve, and midsystolic closure of aortic valve.

Adverse associations
Ethanol in patients with HC increases systolic blood pressure, and the pressure gradient across left ventricular outflow tract.

Management
• Symptomatic—i.e., relief of dyspnoea or chest pain.
• Drugs—beta-adrenergics are effective short-term, calcium channel blockers (which increase diastolic ventricular filling) may be effective long-term.
• Surgery—recalcitrant cases may need a transaortic ventricular septal myotomy-myectomy.

Patient discussion about HOCM

Q. I have hypertrophic cardiomyopathy and an ICD. Is it possible to get breast implants with an ICD? I have no further symptoms: I workout and run 6 days a week, in good shape and only 27 years old.

A. Some medical equipment can damage your ICD If you are visiting your doctor , tell him or her that you have an ICD BEFORE they do any testing or treatment.i'm pretty sure they'll find a creative way to do the implant.any way- before doing any procedure- ask the cardiologist that handles you about it.

Diagnosis of HOCM. Hypertrophic obstructive cardiomyopathy is the thickening of the cardiac ventricles or septum which leads to increased effort in pumping blood due to narrowing of the ventricle [12].
