Cooling ingredients in e-cigarettes may cause irregular heartbeat or cardiac arrest

Article excerpt

Synthetic cooling agents found in e-cigarettes triggered irregular heartbeats and cardiovascular stress in both mice and human heart cells grown in the lab, according to research published in Circulation: Arrhythmia and Electrophysiology. The study, independent from industry funding, identified specific cooling ingredients as culprits, compounds added to e-liquids to create that throat-hit sensation vapers seek. Researchers observed arrhythmias and elevated cardiovascular risk markers in their experiments. The findings add to mounting evidence that e-cigarettes, often marketed as safer alternatives to traditional smoking, carry their own cardiac hazards. The cooling compounds, widely used across the vaping industry, now face scrutiny as potential health risks.
