Patient knowledge about risk factors, achievement of target values, and guideline-adherent secondary prevention therapies 12 months after acute myocardial infarction

Abstract

Aims The prospective GULLIVE-R study aimed to evaluate adherence to guideline recommended secondary prevention, physicians’ and patients’ estimation of cardiac risk, and patients’ knowledge about target values of risk factors after acute myocardial infarction (AMI). Methods We performed a prospective study enrolling patients 9-12 months after AMI. Guideline recommended secondary prevention therapies and physicians as well as patients’ estimation about their risk, and patients’ knowledge about target values were prospectively collected. Results Between 07/2019 and 06/2021 a total of 2509 outpatients were enrolled in 150 German centers 10 months after AMI. The mean age was 66 years, 26.4% were women, 45.3% had STEMI, 54.7% had NSTEMI, 93.6% had revascularization (84.0% PCI, 7.4% CABG, 1.8% both). Guideline recommended secondary drug therapies were prescribed in over 80% of patients, while only about 50% received all five recommended drugs (aspirin, P2Y12 inhibitors, statins, beta-blockers, RAAS inhibitors) and regular exercise was performed by only one third. About 90% of patients felt well informed about secondary prevention, but the correct target value for blood pressure was known in only 37.9% and for LDL-C in only 8.2%. Both, physicians and patients underestimated the objective risk for future AMIs as determined by the TIMI risk score for secondary prevention. Conclusions There is still room for improvement in patient education and implementation of guideline recommended non-pharmacological and pharmacological secondary prevention therapies in patients in the chronic phase after AMI.
