Exercise testing reveals reduced exercise capacity in hypertensive patients, with impaired function worsening with age and end-organ damage. Blood pressure responses during exercise predict future health risks, highlighting the value of this diagnostic tool.
Area of Science:
- Cardiology
- Exercise Physiology
Background:
- Hypertension is a significant cardiovascular risk factor.
- Reduced exercise capacity is common in hypertensive individuals.
Purpose of the Study:
- To review exercise testing in hypertensive patients and those at risk.
- To assess its value in diagnosis, prognosis, and therapy assessment.
Main Methods:
- MEDLINE search (1985-1995) and textbook bibliography review.
- Analysis of primary research on exercise testing in hypertension.
- Assessment of study design, quality, and hemodynamic responses.
Main Results:
- Hypertensive patients show up to 30% reduced exercise capacity compared to controls.
- Impairment correlates with age, end-organ damage, and increased peripheral resistance.
- Exercise blood pressure responses predict hypertension development, end-organ damage, and mortality.
Conclusions:
- Exercise testing is a valuable, simple tool for assessing hypertensive patients.
- Further research is needed to confirm benefits of controlling exercise blood pressure.

Exercise 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...
Exercise 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.
