At the end of this lecture, students will be able to:
CAD is a progressive atherosclerotic disorder of the coronary arteries that results in narrowing or complete obstruction (See picture on next slide).
Atherosclerosis affects the medium-size arteries that perfuse the heart and other organs.
An ECG showing ST-segment elevation (orange) in I, aVL and V1-V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction
Nursing interventions of a patient with angina focus on (Continued…):
A myocardial infarction (2) of the tip of the anterior wall of the heart (an apical infarct) after occlusion (1) of a branch of the left coronary artery (LCA), right coronary artery = RCA.
HDL cholesterol: High-density lipoprotein cholesterol. It is described as good cholesterol because it has protective effect against acute atherosclerosis.
LDL cholesterol: Low-density lipoprotein cholesterol. It is described as the bad cholesterol because high levels are associated with an increased risk of CAD, stroke, and peripheral arterial disease.
VLDL cholesterol: Very-low-density lipoprotein cholesterol. When the triglyceride levels are high, the VLDL level is also high.
