Zhang Weiting sorted out middle-aged and elderly men with high work pressure, smoking habits, high blood pressure, hyperlipidemia, arteriosclerosis and vascular aging history, which are the high-risk groups of aortic aneurysm. They usually have almost no conscious symptoms and are not easy to detect. Once it breaks, it will immediately endanger life. Even with emergency surgery, the mortality rate is still over 50%! In addition to regular inspection to ensure timely detection, Japanese studies have pointed out that taking fish oil can reduce the risk of aortic aneurysm rupture! Aortic aneurysm (English: aortic aneurysm * * *), different from common tumors, refers to the aorta in the chest, abdomen and other parts, and the blood vessels expand abnormally to form a sac. The common causes are hypertension and arteriosclerosis, so people with cardiovascular diseases, three highs and bad smoking habits are prone to occur. Li Menglin, an attending surgeon in the Department of Cardiology, Guotai General Hospital, pointed out that abdominal aortic aneurysms are more common in adults over 50 years old, and the probability of males is 2-6 times that of females, and the probability is about 4-8%. The research team of Feng Jingen University in Japan pointed out that the increase of fat cells on the outer side of blood vessel wall will * * * immune cells, and the oxygen produced will destroy the fibers that protect the blood vessel wall, making the blood vessel gradually unbearable and eventually leading to rupture. Aortic aneurysms are usually not easy to find, and once they rupture, they will be life-threatening. The research team of Feng Jingen University conducted a study to reduce the risk of rupture, and found that mice with aortic aneurysm ate fish oil, which reduced the risk of rupture compared with mice in the same state. DHA and EPA contained in fish oil can reduce triglycerides, soften blood vessels and prevent arteriosclerosis, so it can also prevent the rupture of large aneurysms caused by arteriosclerosis. When taking natural fish oil from food, it is generally believed that green back fish is rich in EPA and is the main source of intake. However, if you are a vegetarian or allergic to fish and seafood, you can also choose kelp or seaweed, which also contain EPA.
