Inhaling Nicotine is Directly Linked With Pulmonary Hypertension

Inhaling nicotine leaves adverse effects on human health. For a start, it raises the pulse and blood pressure (hypertension) and narrows the supply routes. Also, hardening the walls of arteries can cause heart failure or stroke in the future.

A new study published in the journal Hypertension finds that inhaling nicotine alone increases blood pressure (hypertension) in the general circulation of the body as well as in the lungs that can prompt pulmonary hypertension.

In this study, the researchers also found that nicotine-induced pulmonary hypertension is joined by changes in the size, shape, and functioning of the right lower chamber of the heart and the blood vessels in the lungs.

The most significant risk factor that causes lung and cardiovascular diseases are cigarette smoking, the nicotine role in developing lung and cardiovascular diseases has not been surely known.

The researchers recorded that inhalation of nicotine increases diastolic blood pressure and systemic systolic. A Ph.D., Professor of Pharmacology at LSU Health New Orleans School of Medicine, Eric Lazartigues tells that this increase was transient, however, it was adequately long to present potential health risks in people with previous cardiopulmonary conditions.

The scientists associate Pulmonary hypertension with the remodeling of the lung blood vessels. This study suggests that chronic inhalation of nicotine prompts muscularization of previously non-muscular pulmonary arterioles consistent with increased pulmonary vascular resistance and right ventricular systolic pressure.

The major reason behind the death in pulmonary hypertension is the Right ventricle failure. The specialists found a 56 days exposure to nicotine caused higher right ventricular systolic pressure as well as enlargement of the right ventricle.

 Xinping Yue is an Assistant Professor of Physiology at LSU Health New Orleans School of Medicine. In this study, she tells that the adverse effects of nicotine are mainly severed to the right heart, as the researchers found no noteworthy changes in protein expression or left heart remodeling.

A 2016 study shows that cigarette smoke weakens the functioning of the immune system. The researchers found that even social or incidental smoking can cause significant harm to a person’s body, prompting issues like hypertension and high blood pressure. The results of the Surgeon General’s 2014 report shows, there is convincing proof that smoking is associated with a higher risk of respiratory viral infection.

A report from the Centers for Disease Control and Prevention (CDC) shows that the main cause of preventable disease, disability, and death in the United States is tobacco use. The 2018 data shows there were more than thirty million US adults smoke cigarettes. Every day, around two thousand adults in the United States, smoke their first cigarette, and more than three hundred starts smoking daily

More than 16 million individuals live with a disease that caused in them due to smoking and more than fifty million nonsmoking Americans are exposed to used smoke. Three years before, it was reported that 25% of youth of Louisiana high school currently utilizing any tobacco item, including e-cigarettes, and 12.3 % are smoking cigarettes among Louisiana secondary school youth.

An Associate Professor of Physiology at LSU Health New Orleans School of Medicine, Jason Gardner says, “There is a frightening trend of increasing usage of e-cigs and vape products in youths and young adults. Recent high-profile cases of hospitalization and death following e-cig usage necessitate a greater understanding regarding the health impact of inhaled nicotine delivery systems.”

The present study clearly shows the adverse effects of nicotine inhalation on pulmonary blood pressure, systematic blood pressure, and cardiac remodeling.

She further said, “This study should help raise the awareness of the adversative effects of nicotine inhalation on the cardiopulmonary system and help formulate public health policies on e-cigarettes.”
