Heart Attack Locations Flashcards
What happens when right coronary artery gets blocked?
Posterio-inferior pattern of cell death: Posterio-inferior wall of the ventricle and posterior 1/3 of interventricular septum. 35% of cases.
What happens when Left circumflex artery gets blocked?
Later wall of the left ventricular pattern of cell death. 15% of cases.
What happens when left coronary artery is obstructed at a site near its origin from the aorta?
Massive anteroseptal AMI of left ventricle: death of person from cardiogenic shock.
What is the best time for reperfusion therapy?
Within first 6 hours since the initial symptoms.
When should oxygen supplementation be started?
When
When can we start treatment for someone suspected of having an AIM?
When presenting typical symptoms of AIM and EKG changes.
What medication can we give as soon as AIM is suspected?
Aspirin (chewable better) 102-325 mg for immediate protection.
Clopidogrel 300 mg for long term protection.
Some combine both for “double protection”.
What do Q waves in leads V1-V3 indicate?
Anteroseptal infarction.
What do Q waves in leads V1-V6 indicate?
Anterolateral AMI.
What happens when the Anterior Descending branch of the left coronary artery gets blocked?
Anteroseptal pattern of cell death: anterior wall of the left ventricles and apex of the heart and anterior 2/3 of the intervetricular septum. It is 45% of heart attacks.
