Objective:
Many health care providers encounter patients with complaints of calf pain, swelling, chest pain, shortness of breath, and syncope after intense exercise. Unfortunately, these symptoms alone or in constellation could represent an underlying venous thromboembolism. A negative D-dimer can often exclude moderate-risk patients. We examined the change in D-dimer levels following strenuous exercise.
Methods:
In a prospective study of 42 sailors, D-dimer levels were drawn before and after a workout that simulated the standardized Navy Physical Readiness Test. Data were analyzed using the Kruskal-Wallis and Kolmogorov-Smirnov tests.
Results:
No significant change was found between pre- and postexercise levels.
Conclusion:
Findings indicate that neither level of conditioning, nor short, intense exercise affected D-dimer levels in participants who were considered extremely at low risk for thromboembolic disease. In essence, this allowed us to test the test, and therefore adds to our understanding of a screening tool used in the pursuit of a disease with significant consequence.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
