The patient has recurrent VTE, which places her in the “High” risk stratum for arterial or venous thrombosis according to the table.

Memory Tool:
Remember, “Recurrent VTE means Really High Risk.”

Reference Citation:
Table 8.4, Paragraph 1

Rationale:
Recurrent VTE significantly increases the risk of future thrombotic events, making it crucial to identify these high-risk patients for appropriate management.

Question 68

Question 9: Topic - VTE and Thrombosis Risk
Clinical Vignette:
A 65-year-old male has been receiving palliative treatment for active cancer. What is his risk stratum for arterial or venous thrombosis?

Multiple Choice Options:
A. Low
B. Moderate
C. High
D. Not Applicable

Answer 68

Correct Answer:
C. High

Explanation:
The patient has active cancer that’s either been treated within the last 6 months or is palliative, placing him in the “High” risk stratum for arterial or venous thrombosis according to the table.

Memory Tool:
For active cancer, think “Cancer is a High Concern,” reminding you of the high-risk category.

Reference Citation:
Table 8.4, Paragraph 1

Rationale:
Patients with active cancer are at an elevated risk for thrombotic events, making correct risk stratification essential for appropriate clinical management.

Question 69

Question 10: Topic - Mechanical Heart Valve and Thrombosis Risk
Clinical Vignette:
A 38-year-old male has a bileaflet aortic valve prosthesis along with atrial fibrillation and a history of stroke. What is his risk stratum for arterial or venous thrombosis?

Multiple Choice Options:
A. Low
B. Moderate
C. High
D. Not Applicable

Answer 69

Correct Answer:
C. High

Explanation:
The patient has a bileaflet aortic valve prosthesis and additional risk factors, such as atrial fibrillation and a history of stroke. According to the table, this places him in the “High” risk stratum for arterial or venous thrombosis.

Memory Tool:
Think “High Stakes for High Risks” when multiple risk factors like atrial fibrillation and stroke history are present alongside a bileaflet aortic valve prosthesis.

Reference Citation:
Table 8.4, Paragraph 1

Rationale:
Multiple risk factors in patients with mechanical heart valves necessitate a higher level of vigilance and may require more aggressive therapeutic strategies.

Question 70

Question 11: Topic - Atrial Fibrillation and Thrombosis Risk
Clinical Vignette:
A 50-year-old female has atrial fibrillation and a CHADS2 score of 5. What is her risk stratum for arterial or venous thrombosis?

Multiple Choice Options:
A. Low
B. Moderate
C. High
D. Not Applicable

Answer 70

Correct Answer:
C. High

Explanation:
The patient has a CHADS2 score of 5, which places her in the “High” risk stratum for arterial or venous thrombosis according to the table.

Memory Tool:
Think “High 5 for High Risk” to remember that a CHADS2 score of 5 or higher puts you in the high-risk category.

Reference Citation:
Table 8.4, Paragraph 1

Rationale:
A high CHADS2 score indicates a significantly increased risk for thrombotic events, making it essential to understand how it impacts risk stratification and treatment choices.

Question 71

CHADS2 Score
The CHADS2 score is a clinical prediction rule for estimating the risk of stroke in patients with non-rheumatic atrial fibrillation (AF), a common and serious heart arrhythmia associated with thromboembolic stroke. The acronym CHADS2 stands for:

C: Congestive heart failure (1 point)
H: Hypertension (1 point)
A: Age ≥75 years (1 point)
D: Diabetes Mellitus (1 point)
S2: Prior Stroke or TIA or thromboembolism (2 points)

Answer 71

The total score is calculated by summing up the points for each risk factor present in the patient, and it ranges from 0 to 6. A higher score indicates a higher risk of stroke.

Question 72

Bridging Anticoagulation
“Bridging” anticoagulation refers to the practice of temporarily administering a short-acting anticoagulant, usually low-molecular-weight heparin (LMWH) or intravenous unfractionated heparin, during the perioperative period when long-acting oral anticoagulants are held.

How It’s Performed:
Preoperative Phase: The oral anticoagulant is stopped a few days before surgery to allow for its anticoagulant effect to wane.
Bridging Phase: Starting about 2 days after stopping the oral anticoagulant, a short-acting anticoagulant like LMWH is administered subcutaneously.
Surgery Day: The bridging anticoagulant is usually stopped 24 hours before the procedure.
Postoperative Phase: Bridging is resumed postoperatively, usually within 24 hours after surgery, once the risk of surgical bleeding is low.
Resumption: The long-term oral anticoagulant is restarted when it’s safe, and the bridging anticoagulant is discontinued once the oral agent reaches its therapeutic level.
