Key result
A 20-year-old collegiate athlete was diagnosed with a pulmonary embolism despite being PERC negative, demonstrating that elite athletes' lower resting heart rates can mask relative tachycardia.
Why the study?
Evaluating elite athletes for pulmonary embolism requires caution with the PERC rule because their low resting heart rate and athletic-specific risk factors differ from the general population.
Case Report (n=1)
Elite athletes may present with relative tachycardia that appears normal by standard criteria, necessitating caution when using the PERC rule to rule out pulmonary embolism.
INTRODUCTION: The clinical presentation of pulmonary embolism (PE) is often associated with classic vital instability such as tachycardia, hypoxia, and tachypnea. This critical diagnosis is often less likely if a patient is negative by Pulmonary Embolism Rule-Out Criteria (PERC) standards with a low pre-test probability of disease. Caution must be used when evaluating elite athletes with the PERC rule due to low resting heart rate and certain risk factors, which are inherent to athletics. CASE REPORT: We report the case of a 20-year-old male Division 1 collegiate athlete with pleuritic chest pain diagnosed with PE despite being PERC negative. His presenting heart rate (HR) of 79 beats per minute was correctly determined to be tachycardic relative to his resting HR of 47-60 beats per minute. Despite his PERC negative status, PE was found after an elevated D-dimer and subsequent computed tomography angiography. CONCLUSION: Special consideration should be used when evaluating elite athletes for PE, as their resting physiology may differ from the general population. Additionally, certain risk factors for thromboembolic disease are inherent in competitive athletics and should be considered during an initial risk assessment. The presented patient was successfully treated with oral anticoagulation for three months and was able to return to play.
