Block 2 Case 8 - IHD


A man presents with crushing chest pain that is present at rest. He previously was able to relieve his pain with rest but now the pain is occurring when he is sitting at his desk and work. It is escalating in frequency and   intensity. He presents to the ER concerned that he is having an MI. His initial troponin level is negative but when it is retested two hours later it is found to be elevated.

If a biopsy of his heart looked like the following slide -how long would you estimate the ischemia had been occurring?

    IHD is caused by an inbalance between oxygen supply and demand of the myocardium. What three things does oxygen demand depend on?

    Name two reasons why there oxygen demands would not be met despite adeuqate blood-flow:

    1.  
    2.
