International ECP Patient Registry
The International ECP Patient Registry (IEPR) at the Epidemiology Data Center of the University of Pittsburgh Graduate School of Public Health was established in January 1998 to track the outcomes of angina patients who have undergone ECP therapy. More than 100 centers participated in the registry enrolling 5,000 patients. Phase 2 of the IEPR, enrolled an additional 2,500 angina patients with coexisting heart failure and other conditions. Enrollment began in January 2002, and was completed in September 2004.
The IEPR provides the medical community with a vital source of information about the effectiveness of ECP therapy in real-world environments. Data analyzed by the IEPR include improvement in anginal symptoms, duration of benefit, quality of life, effects seen in important patient subgroups and adverse events occurring during the treatment period.
