Background:
An executive health examination is offered at many hospitals for "busy executives" that comprises of a typical history and examination along with screening tests for major cardiovascular and respiratory illnesses. Exercise stress tests are also frequently included in such packages, though the appropriateness of such stress testing remains uncertain.
Aim:
To assess the appropriateness and cost-effectiveness of exercise stress tests performed as part of executive health examinations.
Materials And Methods:
Records of all individuals who underwent an executive health examination at our institution between January, 2007 and December, 2012 were retrospectively reviewed. Data were collected pertaining to demographics, cardiovascular risk factors, indication of stress testing and results of exercise stress tests.
Results:
Of a total of 1650 subjects who underwent exercise stress tests as part of executive health examinations, indication for exercise stress testing was class IIb or III (as per American College of Cardiology's appropriateness criteria) in 96.1 % of subjects. The cumulative cost and time burden of testing for these subjects were Rs. 11,419,200/- PKR (≈$114,192 USD) and 2 weeks and 4 days, respectively. Exercise stress tests were not positive for ischemia in any such cases.
Conclusion:
Based on the results of this study, exercise stress tests should not be routinely offered as part of executive health examinations.

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.
Purposes
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...

TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
