研究目的:

长期饮酒的人群,血浆SAH水平增高,是心血管疾病高危因素。本项目研究目的为探索营养补充剂甜菜碱降低血浆SAH水平,在改善心血管早期事件内皮舒张功能中的确切作用。本项目拟邀请长期饮酒的心血管疾病高危人群,研究营养补充剂甜菜碱是否可以改善其动脉内皮舒张功能。  

Objectives of Study:

In individuals with long-term alcohol consumption, elevated plasma SAH levels constitute a high-risk factor for cardiovascular diseases. The objective of this project is to investigate the precise role of the nutritional supplement betaine in reducing plasma SAH levels and improving endothelial dilation function in early cardiovascular events. This project plans to enroll a high-risk cardiovascular population with long-term alcohol consumption to study whether the nutritional supplement betaine can improve their arterial endothelial dilation function.
