“Heat-not-burn<\/a>” tobacco products, created as an alternative to other types of smoking<\/a>, may harm the user’s heart<\/a>, researchers report.<\/p>\n These tobacco products — think IQOS from Philip Morris — are billed as substitutes for e-cigarettes<\/a> or traditional smokes. But a new review finds they may be tied to heart<\/a> and blood vessel harms.<\/p>\n Researchers found the inhalants were linked to high blood pressure<\/a>, reduced dilation of blood vessels, stiffening of the arteries, increased heart rate and reduced heart function<\/a>. They also show a higher risk of heart arrhythmia<\/a>, or abnormal heart rhythm, in people with pacemakers.<\/p>\n For their paper, researchers from Louisiana State University (LSU) Health Sciences Center in New Orleans analyzed nearly 50 human and rodent studies.<\/p>\n Heat-not-burn<\/a> products are relatively new in the United States and include noncombustible cigarettes.<\/p>\n They feature tobacco heated to a lower temperature than traditional cigarettes. This releases a tobacco-flavored vapor that contains nicotine<\/a>, but does not produce fire, smoke or ash, the authors explained in background notes.<\/p>\n But they do release aerosol particles that pollute the air with chemicals and molecules that can cause DNA damage and cell death, the authors noted.<\/p>\n Studies have suggested that the types of lung injuries associated with e-cigarettes<\/a>, which heat liquid nicotine<\/a>-containing chemicals, could cause users to turn to the “heat-not-burn<\/a>” devices. However, the body of research on these new tobacco products is small.<\/p>\n The new review was published online recently in the American Journal of Physiology-Heart and Circulatory Physiology<\/i>.<\/p>\n “Further clinical, animal and in vitro studies must be developed to explore the cardiovascular effects of [heat-not-burn<\/a>] tobacco products,” said co-authors Jason Gardner and Nicholas Fried, from the physiology department at LSU.<\/p>\n Additional research “will assist lawmakers and regulatory bodies around the globe in making informed decisions regarding this novel nicotine-delivery method,” they added in a journal news release.<\/p>\n — Cara Roberts Murez<\/p>\n![\"MedicalNews\"](\"https:\/\/images.medicinenet.com\/images\/HealthDay\/healthday.png\")
