[New-onset angina pectoris: clinical aspects, diagnosis, prognosis and treatment tactics]

NOA patients are not a homogeneous population in relation to impairment of coronary circulation, clinical symptoms and prognosis. Early hospitalization and treatment of the disease result in more favourable hospital and long-term responses than in the overall population of coronary patients. Conservative and surgical treatment in them produce almost similar results as regards survival and incidence of acute myocardial infarction. Hence, it is thought justifiable to use drugs in the majority of NOA patients leaving surgery only for patients with grave multiple coronary lesions and resistance to chemotherapy.
