Highlighting the need for better patient care in stable angina: results of the international Angina Treatment Patterns (ATP) Survey in 7074 patients.

BACKGROUND
Stable angina is a growing problem worldwide. Diagnostic methods and treatment regimens are established but data on actual practice are sparse and pre-date current guidance.


OBJECTIVES
To compare diagnosis and treatment information with guideline recommendations, and to assess impact on quality of life.


METHODS
This international epidemiological survey recruited patients through primary and secondary care clinicians from China, Czech Republic, Greece, Hungary, Portugal, Russia and Slovak Republic. Participants experienced at least one episode of stable angina within the previous four weeks. Outcomes included use of diagnostic techniques, pharmacological treatments, surgical intervention, secondary prevention and quality of life.


RESULTS
The study included 7074 patients, average age 63.3 (sd 10.3). Diagnosis of angina was most frequently as a result of chest pains (87.4%) with confirmation by resting ECG in only 54.9%. Advice regarding risk factors was frequently given although secondary prevention was often ineffective with 41% of treated hypertensives lacking effective control. 97% of patients were taking at least one of the primary therapies for stable angina recommended by the guidelines with rates of individual therapies varying greatly across countries. Quality of life was lowest in countries with low rates of surgical intervention and poor observance of guidelines on pharmaceutical therapy.


CONCLUSION
Results show that the management of patients with stable angina does not meet recommended standards, although the appropriateness of these guidelines in poorer countries needs further investigation. Overall, the survey indicates that improved medical care and risk factor management would enhance prognosis and improve quality of life.
