STUDY: The vape more harmful than tobacco for cardiovascular health?

Could the e-cigarette be more harmful to cardiovascular health than smoking? This is in any case what reveals a new study carried out by the Cedars-Sinai Medical Center Los Angeles, presented this November 11 at the Scientific Conference of the American Heart Association.


THE VAPE IS THE ORIGIN OF CARDIOVASCULAR PROBLEMS?


Proposed by our colleagues from " T"This new study once again questions the safety of the e-cigarette. In his study, the team Cedars-sinai compared the heart of 10 non-smokers with that of 10 tobacco smokers and 10 electronic cigarette smokers.

All the people who participated in the study were less than 40 years old and were otherwise healthy. In response to a light exercise, blood flow measurements increased in the hearts of non-smokers. Among tobacco smokers, this increase was blunted. But among the users of e-cigarettes, there was no increase at all. "This suggests that e-cigarettes cause an abnormality that interferes with the regulation of blood flow in the heartExplains the Dr. Florian Rader, co-author of the study and heart disease specialist at the Cedars-Sinai Smidt Cardiology Institute.

Dr. Rader pointed out that his study was too small to provide definitive answers and that some of the blood circulation results of e-cigarette users were similar to those of tobacco smokers, and vice versa. In addition, he and his coauthors did not control the use of THC, a compound of marijuana often ingested by vaping. "But averages [of the cardiac function test] were very different for e-cigarette users compared to tobacco smokers", did he declare. " For e-cigarette users, I would say this is another caveat, and that also justifies broader research studies. »

An article published recently in Archives of Disease in Childhood documents the case of a British teenager who nearly died of a vapor induced allergic reaction. The boy of 16 years, previously healthy, entered the hospital after developing a fever, cough and breathing problems that did not improve after a week of antibiotic treatment. He quickly had respiratory failure and needed urgent cardiac and pulmonary help as well as antibiotics and intravenous steroids. He spent 35 days in the hospital and his symptoms did not fully resolve before 14 months.

«It was a sudden and catastrophic disease»Says the Dr. Jayesh Bhatt, co-author of the case study and pediatrician specializing in respiratory care at Nottingham Children's Hospital. Once the boy had recovered, he told his doctors that he had recently started vaping using two types of flavored e-liquid. They diagnosed him with hypersensitivity pneumonitis, a kind of uncontrolled lung inflammation, probably caused by one of the electronic cigarette chemicals he had inhaled.
