Exercise test in patients over 65 years of age after the first myocardial infarction
Abstract:
In 171 patients a submaximal exercise test was performed 3-6 weeks after the first acute myocardial infarction. No complications in connection with exercise test were observed. The incidence of ST/T-segment changes was significantly higher in patients over age 50. Patients over age 60 have a significantly higher incidence of PVCs as well as complex ventricular arrhythmias. In this patient group the incidence of ventricular arrhythmias was higher in patients with ST/T-segment changes during exercise. In the younger patients there was no correlation between incidence of ST/T-segment changes and arrhythmias. A high percentage of patients with no arrhythmias during exercise also had no arrhythmias during Holter. During follow up the average mortality rate was 3.6% and was not significantly different in the four age groups.

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.
Purposes
Imaging Studies for Cardiovascular System I:Echocardiography
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...
