People living with HIV have a higher risk of stroke compared to the general population. Research suggests the risk is approximately 1.5-2 times higher, driven by chronic inflammation from HIV itself, side effects of some antiretroviral medications, and a higher prevalence of traditional cardiovascular risk factors like smoking and high cholesterol.
If you’re living with HIV, understanding your stroke risk and how to reduce it is an important part of long-term health management.
Why Does HIV Increase Stroke Risk?
Chronic inflammation
Even with well-controlled HIV on antiretroviral therapy (ART), low-level inflammation persists in the blood vessels. This chronic inflammation damages the lining of arteries (endothelium), promoting atherosclerosis (fatty plaque buildup) and increasing the risk of blood clots that can cause strokes.
Some older ART drugs, particularly protease inhibitors, are associated with metabolic changes including increased cholesterol, triglycerides, and insulin resistance. These changes contribute to cardiovascular disease and stroke risk. Newer drugs have fewer metabolic effects, but the association remains for some regimens.
Traditional risk factors
People living with HIV have higher rates of several stroke risk factors:
- Smoking (higher prevalence in HIV-positive populations)
- High cholesterol (partly medication-related)
- Diabetes or insulin resistance
- High blood pressure
- Recreational drug use (particularly stimulants)
HIV itself
Uncontrolled HIV (high viral load, low CD4 count) significantly increases cardiovascular risk. The virus can directly infect blood vessel cells, cause immune activation that damages arteries, and trigger coagulation abnormalities.
Types of Stroke in People with HIV
| Type | Cause | More Common in HIV? |
|---|---|---|
| Ischaemic stroke | Blood clot blocks artery to brain | Yes — most common type in HIV |
| Haemorrhagic stroke | Bleeding in the brain | Slightly increased risk |
| TIA (mini-stroke) | Temporary blockage resolves on its own | Warning sign — seek urgent medical help |
How to Reduce Your Stroke Risk
- Stay on ART: An undetectable viral load significantly reduces inflammation and cardiovascular risk
- Stop smoking: The single most impactful lifestyle change for cardiovascular health
- Monitor cholesterol: Regular blood tests. Statins if needed (check interactions with ART)
- Control blood pressure: Aim for below 140/90 (or lower if your doctor advises)
- Exercise regularly: 150 minutes of moderate activity per week
- Maintain a healthy weight
- Limit alcohol
- Discuss your ART regimen: If your current drugs are affecting cholesterol or blood sugar, your HIV specialist may consider switching to a more metabolically neutral combination

Frequently Asked Questions
Does HIV treatment reduce stroke risk?
Yes. Being on effective ART with an undetectable viral load significantly reduces cardiovascular risk compared to untreated HIV. However, some ART drugs have metabolic side effects that need monitoring.
At what age should I worry about stroke if I have HIV?
Studies suggest cardiovascular events occur 5-10 years earlier in people with HIV compared to the general population. Cardiovascular risk assessment should start earlier and be reviewed regularly with your HIV clinic.
Can I take statins with HIV medication?
Yes, but some statins interact with certain ART drugs (particularly protease inhibitors and cobicistat). Your HIV specialist and GP can choose a statin that’s safe with your specific regimen. Pitavastatin and pravastatin have the fewest interactions.
