Chapter 11: Chest Pain Flashcards
Most common cause of chest pain
GI causes
Precipitated by an imbalance between myocardial oxygen requirements and myocardial oxygen supply
Myocardial Ischemia
Causes of increase Myocardial oxygen demand
increases in heart rate, ventricular wall stress, and myocardial contractility
Determines myocardial oxygen supply
coronary blood flow
coronary arterial oxygen content
Nerves involved in referred cardiac pain
Upper 5 thoracic sympathetic ganglia
Upper 5 distal thoracic roots of the spinal cord
cardiac vagal afferent fibers synapse in the _________
nucleus tractus solitarius of the medulla
Tract/Route involved in anginal experience perceived in neck and jaw
Upper cervical spinothalamic tract
pain of pleural pericarditis is often referred to the____
shoulder and neck
Involvement of the____________ can lead to pain in the upper abdomen.
pleural surface of the lateral diaphragm
triggered by an emotionally or physically stressful event and may mimic acute MI because of its commonly associated ECG abnor- malities, including ST-segment elevation, and elevated biomarkers of myocardial injury.

a tear in the aortic intima, resulting in separation of the media and creation of a separate “false” lumen
Aortic dissection
ulceration of an aortic atheromatous plaque that extends through the intima and and into the aortic media
Penetrating ulcer
aortic wall hematoma with no demonstrable intimal flap, no radiologically apparent intimal tear, and no false lumen
Intamural hematoma
Area of aortic dissectionthat presents with cause pain in the midline of the anterior chest
Ascending aorta
