Weight Loss Via Intelligent Guidance in Patients With Coronary Heart Disease and Obesity: a Randomized Clinical Trial
Recruiting now · Not applicable
Conditions studied: CHD, Overweight or Obese
In brief
Coronary Heart Disease (CHD) is an ischemic heart disease caused by coronary atherosclerosis, and it is the leading cause of death from cardiovascular diseases worldwide. Weight loss in obese patients can significantly improve metabolic indicators such as dyslipidemia and insulin resistance; therefore, weight loss may become a target for improving the prognosis of obese patients with coronary heart disease. This study is a multicenter, randomized controlled clinical trial aimed at evaluating the effect of software-based healthy weight loss guidance (personalized diet + exercise intervention) in obese patients with coronary heart disease. It is expected that 136 patients will be enrolled in hospitals including Guangdong Provincial People's Hospital, with a total study duration of 1 year.
