A patient with known coronary artery disease is scheduled for elective hip replacement. Preoperative stress testing is MOST indicated when:
Answer: The patient has poor functional capacity (<4 METs) and findings would change management
ACC/AHA guidelines recommend preoperative stress testing only when the patient has poor functional capacity AND the results would change perioperative management or revascularization strategy.
In patients with long QT syndrome (LQTS), which genotype is associated with the HIGHEST risk of cardiac events during exercise or emotional stress?
Answer: LQT1
LQT1 patients carry the highest risk of arrhythmic events during exercise or sympathetic activation due to the loss of function in the IKs potassium channel.
The Seattle Heart Failure Model (SHFM) is used to estimate which clinical endpoint in heart failure patients?
Answer: 1-year and 5-year survival
The Seattle Heart Failure Model estimates 1-, 2-, and 5-year survival in patients with systolic heart failure using clinical, laboratory, and medication data.
In the context of TAVR risk stratification, the Society of Thoracic Surgeons (STS) Predicted Risk of Mortality (PROM) score of >8% classifies a patient as:
Answer: High risk
An STS PROM score >8% has traditionally defined high surgical risk in the context of TAVR eligibility criteria used in pivotal trials.
Which of the following best describes the role of C-reactive protein (hsCRP) in cardiovascular risk stratification?
Answer: Reclassifies intermediate-risk patients when added to traditional risk factors
hsCRP adds incremental prognostic value to traditional risk factors and is used to reclassify intermediate-risk patients, as demonstrated in the JUPITER trial and pooled cohort guidelines.
A patient with dilated cardiomyopathy, LVEF 30%, NYHA Class II symptoms, and LBBB with QRS duration of 155 ms is on optimal medical therapy. Which risk-reducing intervention is MOST indicated?
Answer: Cardiac resynchronization therapy with defibrillator (CRT-D)
CRT-D is a Class I indication in patients with LVEF ≤35%, NYHA Class II-III symptoms, and LBBB with QRS ≥150 ms on GDMT, providing both mortality benefit and resynchronization.
Which parameter from a cardiopulmonary exercise test (CPET) is the STRONGEST independent predictor of cardiovascular mortality in heart failure patients?
Answer: Peak VO2
Peak VO2 is the strongest independent predictor of cardiovascular mortality in heart failure and is used to guide cardiac transplant listing (threshold typically <12-14 mL/kg/min).
