What long-term heart effects has pregabalin (Lyrica) been studied for?
Research on pregabalin’s heart-related outcomes over the long term is limited. Most evidence on cardiovascular effects comes from short- to medium-duration clinical trials, safety follow-ups, or secondary analyses rather than large, multi-year studies focused specifically on “long-term heart effects.”
What do clinical studies suggest about the heart with pregabalin?
Across clinical development, pregabalin has been monitored for cardiovascular adverse events (for example, heart rhythm problems, blood-pressure changes, and heart-related symptoms). The kinds of signals clinicians watch for long term include:
- Worsening fluid retention or swelling that could indirectly stress the heart.
- Potential effects on heart rate or conduction/arrhythmia risk.
- Changes in blood pressure (either direction).
However, the available published trial evidence is not the same as having definitive, years-long data showing whether pregabalin increases or decreases risk of long-term cardiovascular outcomes such as heart failure, myocardial infarction, or stroke.
Are there specific “long-term” cardiovascular studies in high-risk groups?
For high-risk patients (people with existing cardiovascular disease, older adults, or those with conditions that increase risk of fluid retention), long-term data tend to come from broader post-marketing safety surveillance and subgroup safety reporting rather than dedicated long-term randomized outcome trials.
What side effects make heart monitoring relevant in practice?
Even without strong long-term cardiovascular outcome data, clinicians often consider pregabalin-related adverse effects that can matter to the heart over time, especially if they appear or worsen after starting or increasing the dose:
- Peripheral edema (swelling), which can be clinically important if it develops or worsens.
- Dizziness or lightheadedness, which can affect overall cardiovascular stability.
- Weight gain in some patients, which can be relevant for cardiometabolic risk over time.
If someone develops new or worsening shortness of breath, rapid weight gain, significant leg swelling, chest pain, or fainting, that is typically treated as a prompt-medical-evaluation situation rather than waiting to see if it resolves.

What I need from you to answer more precisely
If you tell me:
1) your time horizon (for example, “after 1 year” or “after 5+ years”),
2) whether you mean heart failure, arrhythmias, or heart attack/stroke risk, and
3) whether you’re asking as a patient on Lyrica or for general research,
I can narrow to the most relevant categories of studies and outcomes.
