This guideline covers coronary heart disease symptoms, diagnosis and treatment. Stable coronary heart disease refers to a disease in, which patients have stable symptoms and evidence of ischemia or significant stenosis of coronary artery. Diagnosis is based on medical history and exercise test, which is the primary diagnostic test. Coronary angiography is in selected cases necessary to confirm the diagnosis and assess invasive treatment. Pharmacotherapy aims to improve the survival of the patient, relieve symptoms and improve quality of life. The guideline also deals with invasive treatment either with PCI or CABG.
