Heart disease bad in my family, looking for ways to keep arteries clean.heard cayenne pepper is good for that,true? any other ways, tyvm

It is unlikely: that Cayenne pepper would have any meaningful affect on your coronary arteries otherwise we would routinely prescribe it to our heart patients (which we don't.) You can't do anything about your genes but you an not smoke, exercise regularly, maintain a low-normal body weight and treat diabetes, hypertension and hyperlipidemia with appropriate medications if you have those disorders.
