Patients with diabetes are susceptible to cardiovascular disease, which is two to four times more common than in the non-diabetic population. Moreover, studies have found that cardiovascular pathology is not only present in patients with longer duration of diabetes, but many newly diagnosed patients already have cardiovascular pathology, including coronary artery disease. This may be related to the insidious onset of diabetes and the failure to diagnose the disease in time due to the lack of obvious symptoms in patients. Diabetes is medically said to be an equivocal risk for coronary heart disease, meaning that diabetic patients without coronary heart disease have the same risk of coronary heart disease as non-diabetic patients with a previous history of coronary heart disease, i.e., the risk of a new cardiovascular event (e.g., myocardial infarction or death from coronary heart disease) is the same for diabetic patients and coronary heart disease patients within 10 years. Cardiovascular disease is the leading cause of death in patients with diabetes. This is because diabetic patients often have insulin resistance and hyperinsulinemia, often accompanied by a variety of cardiovascular risk factors, such as hypertension, dyslipidemia, obesity, proteinuria, which can lead to functional and structural changes in the blood vessels, forming atheroma and atherosclerosis, which, to use a simple analogy, is like “rusting” of blood vessels. So, what tests should be done to check for diabetes? 1.Electrocardiogram (ECG) / ambulatory ECG is not uncommon for diabetic patients with occult myocardial ischemia and myocardial infarction. ECG, including ambulatory ECG monitoring, can show typical changes in coronary ischemia without symptoms or with only plausible recall of symptoms. 2.Carotid ultrasound can show intima-media thickness or plaque formation, which can be used as an alternative basis for coronary artery atherosclerosis. 3.Cardiac ultrasound can assess myocardial structure, myocardial systolic and diastolic function. 4.Exercise plate test is one of the most commonly used aids to diagnose coronary artery disease, which can assist clinical diagnosis of myocardial ischemia by increasing cardiac load, increasing myocardial oxygen consumption and inducing myocardial ischemia. 5.Coronary CT examines the anatomy of coronary arteries without malformation and the presence of obstructive lesions. For the sake of health, Dr. Tang calls on all sugar lovers to actively control blood sugar, receive diabetes health education, and should do early assessment, early prevention, early detection and early treatment of cardiovascular complications of diabetes!
