Exercise Training in Individuals With Coronary Artery Disease

Not Applicable

Completed

• Conditions: Coronary Artery Disease; Myocardial Infarction
• Interventions: Other: Exercise training

• Registration Number: NCT03821558
• Lead Sponsor: University Medical Centre Ljubljana

Brief Summary

In this controlled trial, patients referred to post-myocardial infarction cardiac rehabilitation will be randomized to either interval or continuous training.

Detailed Description

The trial would i) compare the acute effects of each exercise type on selected cardiovascular indicators; ii) compare the chronic effects of each exercise type on selected cardiovascular indicators; iii) provide information on the association between acute and chronic effects of each exercise type; iv) provide insight into possible mechanisms of effectiveness of each exercise type; v) identify the most safe and effective exercise type for patients with coronary artery disease.

Arm && Interventions

Group	Intervention	Description
Continuous training group	Exercise training	Patients to be randomized to the 'continuous training group' will have exercise training sessions 3 times per week for a period of 12 weeks. During training, they will undergo moderate continuous exercise training at 75% of peak exercise performance.
Interval training group	Exercise training	Patients to be randomized to the 'interval training group' will have exercise training sessions 3 times per week for a period of 12 weeks. During training, they will undergo interval exercise series composed of high-intensity intervals (80-90% of peak exercise performance) and low-intensity intervals (60-70% of peak exercise performance).
