Are there effective non-statin options for primary prevention?
The short version: yes, there are non-statin drugs that cut heart attacks and strokes in primary prevention, but the honest ones are ezetimibe, bempedoic acid, and colchicine, and each has a catch.
The cleanest hard-outcome evidence is bempedoic acid. In statin-intolerant patients with or at high risk of heart disease, it cut the combined endpoint of cardiovascular death, heart attack, stroke, and revascularization by 13% over about 40 months [3]. That is a real clinical outcome, not a lab number.
Ezetimibe is murkier. In chronic kidney disease it reduced the composite endpoint but did nothing for cardiovascular or total mortality [1]. In acute coronary syndrome the benefit was modest and the trial was amended repeatedly to reach significance [1]. That is not primary prevention, and it is not clean.
Colchicine, an anti-inflammatory, cut the composite endpoint from 9.6% to 6.8% in chronic coronary disease [4]. That is secondary prevention, not primary.
| Drug | Population | Outcome | Result |
|---|---|---|---|
| Bempedoic acid [3] | Statin-intolerant, high risk | CV death, MI, stroke, revasc | 13% reduction |
| Ezetimibe + simvastatin [1] | Chronic kidney disease | Composite CV endpoint | 11.3% vs 13.4% |
| Ezetimibe + simvastatin [1] | Chronic kidney disease | CV or total death | No benefit |
| Colchicine [4] | Chronic coronary disease | Composite CV endpoint | 9.6% → 6.8% |
The LDL-lowering itself is the mechanism, and it is dose-dependent: each 1 mmol/L drop in LDL cut major vascular events by about 22% across 60 trials, with no meaningful difference between statins and non-statins [3][2]. So the question is not whether non-statin drugs work. It is whether you need them, and what they cost you.
Aspirin is the one non-statin with a large primary-prevention literature, and it fails the test. It cut heart attacks but not all-cause mortality, and raised major bleeding from 1.2% to 1.8% [5]. The net is close to zero or negative for most healthy people.
My call: bempedoic acid is the one non-statin with a clean primary-prevention outcome signal, and it is worth considering if you cannot take a statin and your risk is genuinely high. Ezetimibe lowers LDL but has not shown a mortality benefit. Aspirin for primary prevention is a bad trade. Confidence: moderate for bempedoic acid, low for ezetimibe as primary prevention.

Meta-Analysis of Lowering LDL Cholesterol and its Impact on the Cardiovascular System
In this meta-analysis of 29 RCTs, LDL cholesterol lowering reduced major vascular events by 26% per 1 mmol/L in older adults, with risk reduction comparable to younger patients and no significant statin/non-statin difference.

Statins remain the cornerstone of ASCVD prevention; intensification with ezetimibe, PCSK9 inhibitors, and bempedoic acid improves LDL-C control, while registries show most high-risk patients still miss guideline targets.

Prevention of cardiovascular events in patients with stable coronary artery disease: myocardial revascularization or pharmacological treatment?
In stable coronary artery disease, routine revascularization does not clearly improve prognosis over modern medical therapy, but selected high-risk patients and intensified drug therapy (PCSK9 inhibitors, colchicine, rivaroxaban plus aspirin) may reduce events.
