4 out of 4 points
Scenario 1: Myocardial Infarction
CC: “I woke up this morning at 6 a.m. with numbness in my left arm and pain in
my chest. It feels tight right here (mid-sternal).” “My dad had a heart attack when
he was 56-years-old and I am scared because I am 56-years-old.”
HPI: Patient is a 56-year-old Caucasian male who presents to Express Hospital
Emergency Department with a chief complaint of chest pain that radiates down
his left arm. He states this started this morning and has been getting worse,
pointing to the mid-sternal area, “it feels like an elephant is sitting on my chest
and having a hard time breathing”. He rates the pain as 9/10. Nothing has made
the pain better or worse. He denies any previous episode of chest pain. Denies
nausea, or lightheadedness. Nitroglycerin 0.4 mg tablet sublingual x 1 which
decreased pain to 7/10.
Lipid panel reveals Total Cholesterol 424 mg/dl, high density lipoprotein (HDL) 26
mg/dl, Low Density Lipoprotein (LDL) 166 mg/dl, Triglycerides 702 mg/dl, Very
Low-Density Lipoprotein (VLDL) 64 mg/dl
His diagnosis is an acute inferior wall myocardial infarction.
Question:
Which cholesterol is considered the “good” cholesterol and what does it do?
Selected
Answer:
A desirable lab result for Total Cholesterol would be
less than 200 anything between 200-239 is considered
borderline for dyslipidemia, and would require
nutrition changes before it advances to higher levels.
This patient's Total Cholesterol is very high and
increases his risk for Coronary Artery Disease. High
density lipoprotien (HDL) is the "good" cholesterol and
is responsible for reverse cholesterol transport. The
HDL grabs the excess cholesterol in the blood stream
and takes it back to the liver where is is processed and
broken down and eliminated as bile. The higher your
HDL the less likely you will develop heart disease, or
stroke.
Correct
Answer: HDL is considered the good cholesterol because it collects excess
cholesterol in the body cells and transports it to the liver where it is
excreted in the body cells and transports it to the liver where it is
excreted in the body. HDL carries 20-25% of total plasma cholesterol.
