Hello, according to your description, insufficient blood supply to the heart may be related to coronary heart disease, or cardiovascular blockage. Need to check and diagnose, and give treatment according to the test results. You can also take Naoxintong capsules or compound Danshen tablets for treatment. You can also take levoamlodipine besylate tablets, or take Chinese herbal medicine for treatment. And pay attention to a light diet and eat more vegetarian food.

Suggestion: Pay attention to a light diet with low salt and fat, and eat more vegetables such as sweet potatoes, tomatoes and carrots, which can improve patients' physical resistance. Have some green tea. Tea contains a small amount of theophylline, which has a certain diuretic effect and is helpful for patients with myocardial ischemia. There is vitamin C in tea, which can play a good role in preventing and treating arteriosclerosis, but it should not be too concentrated. Eating auricularia auricula every day is helpful to reduce blood viscosity and improve myocardial ischemia.

I hope my answer is helpful to you and I wish you health!
