Main blood tests for patients with coronary heart disease include:
1. Lipid profile: including total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglycerides, used to assess the risk of cardiovascular disease.
2. Blood biochemistry: including blood glucose, lipids, liver function, kidney function, and blood electrolytes, to evaluate the presence of high-risk factors for coronary heart disease such as diabetes and hyperlipidemia.
3. Cardiac enzyme panel and troponin: used to assess whether a myocardial infarction has occurred.
4. N-terminal pro-brain natriuretic peptide (NT-proBNP): this test can be performed if heart dysfunction is suspected, and is useful in evaluating the occurrence of heart failure.
5. Liver function tests: including alanine transaminase (ALT) and aspartate transaminase (AST); abnormal liver function may affect drug metabolism.
6. Kidney function tests: including creatinine and blood urea nitrogen; kidney disease can affect cardiovascular health.
7. Electrolyte levels: such as potassium, sodium, and chloride; electrolyte imbalance may affect cardiac function.
