Scenario :
You are a third-year medical student doing a rotation in the emergency room. A 41 year-old female comes in, complaining of some chest pain and shortness of breath. Physical examination reveals a heart murmur. An electrocardiogram and an echocardiogram are ordered; these tests reveal that the patient likely has hypertrophic cardiomyopathy. The doctor asks you to look up further information on the condition.
Go to OMIM ( http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=OMIM&cmd=Limits )
Search the database for hypertrophic cardiomyopathy
Use the item titled “#192600 Cardiomyopathy, Familial Hypertrophic; CMH” to answer the following questions.
Study Questions:
1. What are the earliest signs of hypertrophic cardiomyopathy?
2. How many types of hypertrophic cardiomyopathy have been described? In general, how are the types distinguished from each other?
3. What factors may increase the risk of cardiovascular events in someone with hypertrophic cardiomyopathy?
4. What are some of the effects of ‘myocardial bridging' in patients with hypertrophic cardiomyopathy?
5. What is the principal mechanism of sudden death in patients with hypertrophic cardiomyopathy? What treatment may prevent this sudden death?
6. What is the relationship between the magnitude of the hypertrophy and the risk of sudden death?
7. Are there risks associated with exercising in patients with hypertrophic cardiomyopathy?
