One of the meta-analyses studied myocardial infarction rates and showed a significantly lower rate (0.6 %; 19/3289 patients) in PCSK9 inhibitor-treated patients compared to those who received no anti-PCSK9 treatment (1.0 %; 19/1906 patients; odds ratio, 0.49; 95 % CI, 0.26–0.93) [19]. Here, PCSK9 is linked to myocardial infarction.
