Unstable angina comprises a heterogeneous population of patients who present with a wide spectrum of underlying pathophysiology. The traditional treatment of these patients is based on both evidenced-based medicine as well as clinical experience. Despite the large population of patients admitted with this diagnosis, the scientific literature regarding its treatment is scarce. Therefore, the management of patients with unstable angina relies heavily on the clinical skills of the physician. One of the most important steps in this process involves risk stratification, especially in the current environment of cost containment. Those patients who are at low risk for adverse outcomes can be treated and evaluated safely as outpatients. Patients at high or moderate risk, however, should be treated intensively as inpatients. Although there appear to be many new promising therapies for unstable angina on the horizon, the traditional therapies still have a place. The use of aspirin in this population is well supported by the literature and appears to have a positive effect on mortality and cardiovascular events. The other traditional therapies, however, are not as well supported by the literature. They do appear to benefit the patient in terms of reducing symptoms, but their effects on reducing mortality and cardiovascular events are not clear. Therefore, the goal of medical therapy in this patient population should be to stabilize them so that they can proceed with an appropriate risk stratification procedure as soon as possible. This is especially true with performing coronary angiography or interventions because the risk of procedural complications is higher in patients with unstable angina and ongoing symptoms.
