What someone who reaches this rule is told

Word for word, as generated for the example person below. Figures in the text are theirs.

  • Strongly recommended

    High-intensity statin therapy, aiming for LDL-C below 55 mg/dL (and non-HDL-C below 85).

    Proven in trialsTrials counted real events, like heart attacks, strokes, or deaths, and this changed them.

    Ask a cardiologist about this one. Which secondary-prevention risk tier you sit in is a judgement this tool can only approximate. It knows about prior heart attack, stroke, and peripheral artery disease, but not how recent they were, whether you have familial hypercholesterolemia, or whether your LDL has stayed above 100 on maximal therapy — all of which feed the definition. Ask your cardiologist which goal applies to you.

    Why, and the source

    You look to be in the guideline's "very high risk" secondary-prevention group — more than one major event, or one event plus several high-risk conditions — which carries the lowest goal in the guideline. If you are on a statin and still above goal, ezetimibe, bempedoic acid, or a PCSK9 inhibitor are the next steps rather than a reason to accept the number.

    • RecommendsClass ILevel A

      Secondary prevention at very high risk: at least a 50% cut and LDL-C below 55 mg/dL; a PCSK9 inhibitor is also Class I, Level A when the goal is missed on a statin plus ezetimibe.

  • Worth raising with your doctor

    Ask your cardiologist whether low-dose colchicine is worth adding.

    Proven in trialsShown: 23% to 31% fewer heart attacks, strokes, and heart deaths in two trials of people with heart disease.

    Why, and the source

    This is one of the more interesting additions to secondary prevention — colchicine at 0.5 mg daily reduced cardiovascular death, heart attack, stroke, or urgent revascularization by 31% in the LoDoCo2 trial, working on inflammation rather than on cholesterol. We stop short of suggesting it directly because it is cleared by the kidneys and interacts with several common drugs, including some statins, clarithromycin, and antifungals. Whether it suits you depends on your kidney function and everything else you take.

      Low-dose colchicine 0.5 mg daily should be considered in chronic coronary syndrome to reduce MI, stroke and revascularization.

    Why this is a question. It would need everything else you're currently taking. This tool doesn't ask for that, so it stays a question.

  • CORALreef Outcomes — The new daily pill version of a PCSK9 inhibitor lowers LDL as much as the injections. Does it also prevent heart attacks and strokes?
