If you’re fact-checking the headline “Popular blood pressure drug linked to increased cardiac arrest risk,” it appears to refer to nifedipine, particularly higher doses.
A 2025 report on research from the European Sudden Cardiac Arrest network said high-dose nifedipine was associated with an increased risk of sudden cardiac arrest.

However, an association does not prove that nifedipine causes cardiac arrest, and the finding shouldn’t be interpreted as meaning that everyone taking nifedipine is in danger.
What patients should know
Don’t stop nifedipine suddenly without speaking with your doctor.
Nifedipine remains an established medication for conditions including high blood pressure and angina.
The potential concern was particularly associated with higher doses, rather than ordinary use automatically being dangerous.
Your individual risk depends on your dose, other medicines, heart health, blood pressure, and other medical conditions.
Bottom line: The headline contains a real research concern but makes it sound more definitive than the evidence supports. If you’re taking nifedipine, tell me the dose (for example, 30 mg or 60 mg) and whether it’s extended-release, and I can explain what the current evidence means for that specific treatment.
