Hello, drinking tea after cardiovascular stent can reduce blood viscosity and blood lipid. However, there must be some selectivity in drinking tea, including the concentration of tea, the variety of tea and the time of drinking tea. In addition, we should also consider the disease itself. It is suggested that patients with coronary heart disease should drink tea lightly and moderately. Because, in addition to causing certain irritation to the gastric mucosa, strong tea will also increase the heart rate because it contains more coffee, which is tantamount to adding insult to injury to people with poor blood supply to the heart. Secondly, in the choice of tea, we should choose green tea, Kuding tea, Pu 'er tea and Oolong tea with the function of clearing away heat and cooling blood. I hope my answer is helpful to you, and I wish you health and happiness.
