Anders Holt, MD from Herlev and Gentofte University Hospital speaks about the Effect of long-term beta-blocker treatment following myocardial infarction among stable, optimally treated patients without heart failure in the reperfusion era: a Danish, nationwide cohort study.


Abstract:


Listen to this contribution's audio abstract at https://doi.org/10.1093/eurheartj/ehaa10588



Targets:


The goal was to research the long-term cardio-protective effect of beta-blocker (BB) therapy in healthy, optimally treated patients with myocardial infarction (MI) without heart failure (HF).



Methods and outcomes:

We included patients with first-time MI undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI) during admission and treated between 2003 and 2018 with both acetyl-salicylic acid and post-discharge statins using national registries. Patients with a previous history of MI, prior use of BB, or any alternative indication or contraindication to treatment with BB have been removed. Follow-up started with patients alive, free of cardiovascular (CV) incidents or treatments, 3 months after discharge. CV death, repeated MI, and a composite outcome of CV events were the primary outcomes. 3 years after MI, we used modified logistic regression and reported standardized absolute hazards and differences (ARD). In total, 30,177 healthy, optimally treated MI patients were included (58 percent acute PCI, 26 percent sub-acute PCI, 16 percent CAG without intervention). 82% of patients were on BB therapy at baseline (median age 61 years, 75% male) and 18% were not (median age 62 years, 68% male). Compared to no BB treatment [ARD (95 percent confidence intervals)], BB treatment was associated with a comparable risk of CV death, recurring MI, and the cumulative outcome of CV events; 0.1 percent (−0.3 percent to 0.5 percent), 0.2 percent (−0.7 percent to 1.2 percent), and 1.2 percent (−0.2 percent to 2.7 percent).



Findings:

No long-term effect of BB treatment on CV prognosis was found in this nationwide cohort study of healthy, optimally treated MI patients without HF in patients aged 3 months to 3 years after MI admission.
