Exercise haemodynamics in patients over 65 years of age with recent myocardial infarction
Abstract:
Five hundred patients underwent exercise testing during haemodynamic monitoring 36 +/- 17 days after an acute myocardial infarction: 136 were 45 or less years of age (group A), 323 aged 46-64 years of age (group B) and 41 were over 64 years of age (group C). Group C showed at rest a lower stroke volume and cardiac output (CO) and during exercise a more frequent ST depression, a higher pulmonary artery end-diastolic pressure at a lower work load and a higher incidence of patients with inappropriate increments of CO. The differences among groups were statistically significant (P less than 0.05) and independent of the extension of necrosis and the presence of myocardial ischaemia. It is concluded that these changes are at least partially age-related.

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.
