Study Overview
Brief Summary
The goal of this clinical trial is to learn about the effects of time-restricted eating in patients with history of acute coronary syndrome. The main questions it aims to answer are: 1) Is 10-hr TRE safe and feasible for patients with ACS; 2)What are the impacts of 10-hr TRE on anthropometric measurements, cardiometabolic health and cardiovascular health compared to ad libitum eating in patients with ACS?. Participants will be asked to limit eating duration to 10 hours daily.
Detailed Description
Justification: The effects of TRE on humans varies results, with some showing improvements in weight loss, insulin sensitivity, and cardiovascular markers, while others exhibiting no significant changes. TRE studies on metabolically altered individuals especially patients with heart diseases are limited.
Written approval of the study has been obtained from the Universiti Teknologi MARA Ethics Committee before commencement of this study.
The TRES study utilizes an investigator-led, pragmatic, parallel, randomized, single-blinded clinical trial design to evaluate the safety, feasibility, and effectiveness of a 10-hour time-restricted eating (TRE) intervention compared to unrestricted eating in patients diagnosed with acute coronary syndrome. The study aims to assess the impact of TRE on anthropometric measurements, as well as cardiometabolic and cardiovascular health outcomes. The duration of the randomized controlled trial (RCT) spans a period of five weeks. The trial consisted of a baseline period of one week, which was then followed by a four-week intervention phase. The participants will be assigned randomly to either the TRE (Time-Restricted Eating) group or the control group, which involves ad libitum eating. They will be instructed to adhere to their allotted eating duration during the four-week intervention period.

Arms & Interventions
Ad-libitum eating duration
24 patients will be randomly assigned to the control group. Participants will be asked to continue usual eating duration. Participants will receive the standard care and heart-healthy nutrition education.
Time-restricted eating (TRE) duration
24 patients will be randomly assigned to the intervention group. Participants in this arm will be asked to limit the number of hours they eat in a day to 10 hours in addition to receiving the standard of care health and heart-healthy nutrition education.
Intervention: Time-restricted eating 10-hr (Behavioral)
