It is well known that uric acid is a product of purine metabolism in human body, and elevated blood uric acid in human body is mainly caused by increased metabolism and decreased excretion of nucleic acid. In clinical practice, fasting serum uric acid is generally >420μmol/L in men and >360μmol/L in women to determine hyperuricemia, and there are many patients with high uric acid in China, according to statistics, as many as 120 million patients with elevated uric acid, and the prevalence is increasing year by year, and the trend is young. As we all know, high uric acid is closely related to gout, and when uric acid rises to a certain level, it will crystallize in the joints to form gout stones, and then clinical symptoms of gout will appear. However, the harm caused by hyperuricemia is much more than that, it can also affect many systems in the body and lead to many diseases. Numerous studies have confirmed the close relationship between hyperuric acid and cardiovascular disease. A study in the United States confirmed through systematic evaluation and meta-analysis that high uric acid and gout increase the incidence of coronary heart disease and mortality in the general population. The risk of coronary heart disease was significantly increased when blood uric acid values were greater than 420 μmol/L. Locally, lowering blood uric acid levels in adult women reduced the incidence of coronary heart disease. Another study, which investigated and analyzed uric acid levels and mortality in 12,373 patients with angiographically confirmed coronary artery disease, found that uric acid would increase mortality in the coronary artery disease patient population. Another study confirmed that blood uric acid levels were positively associated with cardiovascular mortality, with patients who died of ischemic cardiomyopathy having the highest blood uric acid levels. When blood uric acid values exceed 480 μmol/L, serious damage is caused to the structure and function of the heart. The above indicates that hyperuricemia is an independent risk factor for increased mortality in patients with coronary heart disease, especially in women. As the blood uric acid level increases, the prevalence of coronary heart disease and the risk of death also increases. Although hyperuricemia cannot be cured, it should still be treated aggressively to maintain relatively normal blood uric acid levels. This is especially true as people become more health conscious and the concept of upstream treatment (treating the untreated) in clinical medicine is reflected. In people who do not yet have cardiovascular disease, blood uric acid can predispose to cardiovascular disease, and uric acid values are also predictive of cardiovascular disease development. It is important to improve dietary habits and increase physical activity to reduce uric acid levels, and to give medication if necessary. In patients with proven cardiovascular disease, controlling uric acid levels not only helps to treat and control cardiovascular disease, but also reduces the incidence of cardiovascular accidents and mortality.
