Chronic medication intake in patients with stable coronary heart disease across Europe: Evidence from the daily clinical practice. Results from the ESC EORP European Survey of Cardiovascular Disease Prevention and Diabetes (EUROASPIRE IV) Registry.

BACKGROUND

As advised by the European guidelines on cardiovascular prevention, medication intake is a major component of secondary prevention. The aim of this study is to provide an in-depth overview of the medication intake in stable European coronary heart disease (CHD) patients.

METHODS

Analyses are based on the EUROASPIRE IV survey, including CHD patients (18 to 80 years) who were hospitalized for a coronary event. These patients were interviewed and examined 6 months to 3 years after their hospitalization. Information on cardiovascular medication intake is available for 7953 patients.

RESULTS

About 99.2% of patients were on any kind of cardiovascular medication and 67.6% of patients were taking at least 5 different cardiovascular drugs. Overall, even when patients are taking the recommended drug combination as advised by the European guidelines - accounting for their disease profile - a large proportion of patients is still not on blood pressure, LDL-C or HbA1c target. In addition, huge variations were seen in medication dose intake across countries. Comparing the dose intake to the defined daily dose (DDD as published by the WHO) indicated a substantial deviation from the DDDs for a large proportion of patients.

CONCLUSION

This study provides a unique overview of the cardiovascular medication intake in CHD patients. Overall, even when patients are taking the advised drug combination, a large proportion of patients is still not on risk factor target. Physicians should seek for a balance in medication intake and appropriate dose, accounting both for the benefits and risks of chronic drug intake.
