It's because of racism. No, seriously.

If something disproportionately affects black people negatively, it has a significant amount of support from certain voters. The whole origin of the anti-abortion movement in the 19th century was double-pronged to displace midwives (who were often minorities) and that too many white women were getting abortions, which was labelled "race suicide" [1].

Need more? Infant mortality skews heavily by a state being red or blue and by the racial makeup [2]. Iowa is a red dot in a sea of blue because it's particularly white. Compare the US to other developed nations [3].

So this particular issue is with heart disease. And guess what? Black people are disproportionately affected and have worse outcomes [4]. Shocking.

Many people have a shallow view that racism is using slurs. It is not. Racism is systemic. And it's not as direct and nefarious as people in a smoke-filled room getting together to try and create worse heart disease outcomes for black people. It's a series of steps taken such that this problem isn't solved. It's just not prioritized.

You see the same thing with medical misogyny and medical racism. Symptoms are downplayed and ignored. This has been thoroughly tested where doctors have been given a file genders changed and there are statistically different outcomes.
