Triglyceride 5.8mmol/L is more serious, need timely treatment, prone to myocardial infarction, coronary heart disease, acute pancreatitis and other diseases. The normal value of triglyceride should be less than <1.7mmol/L, 1.7 ~ 2.2mmol/L is borderline elevated, greater than 2.3mmol/L is elevated. Triglyceride 5.8mmol/L is more serious and requires prompt treatment. The reference range may vary slightly from hospital to hospital. Severe elevated triglycerides, if not effectively controlled in a timely manner, combined with the patient’s own other risk factors, such as diabetes mellitus, hypertension, etc., are prone to the formation or increase of vascular plaques, which may lead to an increased risk of cardiovascular diseases such as myocardial infarction, ischemic stroke, or coronary heart disease, as well as the possibility of acute pancreatitis. Patients with triglycerides 5.8mmol/L are advised to visit the hospital in time and be treated under the guidance of a doctor to avoid delays.
