Abstract

BACKGROUND:

Limited prospectively collected data are available on the total outcomes, cost estimates, and quality of life associated with treatment of acute coronary syndrome (ACS) through 1 year in a nonclinical-trial setting, or on the impact of new clinical events by 1 year on resource utilization and costs.

METHODS:

The Antiplatelet Therapy Observational Registry (APTOR) 12-month study followed 1,335 concurrently recruited ACS patients undergoing percutaneous coronary intervention (PCI) and treated with antiplatelet therapy from France, Spain, and the United Kingdom in a "real world" clinical setting. Data were collected on clinical events, resource utilization, quality of life, and cost estimates through 1-year follow-up.

RESULTS:

By 1 year, 14.4% (95% CI 12.7-16.4%) of patients experienced a clinical event of death, MI, stroke, unstable angina, urgent target vessel revascularization, or acute heart failure. Costs by 1 year were higher among those who had a new clinical event (£8,988, 95% CI £7,848, £10,395) as compared with those with no events (£5,809, 95% CI £5,486, £6,161). This increased cost was due to higher postdischarge resource use costs. Using the EQ-5D assessment at 1 year, quality of life was directionally lower in those patients who had experienced a new clinical event.

CONCLUSIONS:

The risk of experiencing a new clinical event during the year following an ACS, which was treated with PCI, remains high among European patients, with one-seventh of patients having a new event. These additional clinical outcomes reduce quality of life and increase health care expenditures, expanding the already high cost of treatment for ACS.
