what is most likely cause of Afib in a 24yo male?
A) Congenital prolonged QT syndrome.
B) Hypertrophic cardiomyopathy.
C) Alcohol.
D) Marijuana use.
E) Ischemic cardiac disease.
A 65-year-old male with a history of newly identified
atrial fibrillation is referred to you for medical clearance
for surgery. He has a history of hypertension and
hypercholesterolemia. He has normal cardiac function
otherwise with a normal ejection fraction and no valvular
disease on echocardiogram. His atrial fibrillation
has not been addressed since it was picked up by the
surgeon at a preop visit. His heart rate is 80 beats per
minute when you see him, his rhythm is irregularly
irregular, and he has no signs of heart failure.
Which of the following options would be appropriate
for this patient?
A) Anticoagulate the patient with warfarin and allow
him to stay in atrial fibrillation.
B) Place the patient on aspirin and allow him to stay
in atrial fibrillation.
C) Give digoxin to cardiovert the patient.
D) Strongly suggest cardioversion to this patient since
sustained normal sinus rhythm yields the best
long-term outcomes.
E) Add furosemide to prevent the development of
CHF and edema.
The criteria for lone atrial fibrillation, which
allows one to use aspirin rather than warfarin as
an antithrombotic drug, include all of the following
EXCEPT:
A) No history of hypertension.
B) Age
where are the rest of the options ??
B) Age < 50 yrs
C) Absence of heart failure.
D) No prior history of stroke or transient ischemic
attack.
E) No history of diabetes mellitus
Which of the following approaches is the best for
controlling his anticoagulation given that he
needs surgery?
A) Stop the warfarin several days before surgery to
allow his INR to normalize. Restart the warfarin
after surgery.
B) Hospitalize the patient a couple of days ahead of
time and start heparin. Then stop his warfarin.
Restart the warfarin after surgery.
C) Use low-molecular-weight heparin at home and
stop the warfarin once this is started. Restart the
warfarin after surgery.
D) Stop the warfarin several days before surgery to
allow his INR to normalize. Start heparin after surgery
and simultaneously restart warfarin.
Great topic to me !!!
The patient has his surgery and returns to your clinic
for a postoperative checkup 1 month after his surgery.
You check his INR and it is noted to be 5.2. There is no
active bleeding.
The most appropriate action now is to:
A) Hospitalize the patient for observation since he is
at a high risk of bleeding.
B) Give the patient 5 mg of vitamin K orally.
C) Give the patient 2 units of fresh frozen plasma to
reverse his anticoagulation.
D) Hold the next warfarin dose and reduce the maintenance
dose.
E) A, B, and C.
