We found that vaping had no significant effect on platelet aggregation, as assessed by PFA and LTA, whereas smoking caused a further reduction in the ability of platelets to aggregate, suggesting a further deterioration of platelet function.

How does vaping affect blood flow?
That meant that blood wasn’t flowing as quickly as it was prior to inhaling the vapor. The researchers also found that vaping reduced the amount of oxygen in the blood by 20 percent, and made the walls of the blood vessels more rigid and stiff—a symptom often associated with cardiovascular diseases like hypertension and stroke. Other studies have found similar results in animals, but this is the first such finding in human subjects. “It’s really stunning,” says Sven Jordt, who studies e-cigarettes at Duke University and who was not involved in this study.
How many teenagers are affected by vaping?
Last week, the Centers for Disease Control announced that it is opening an investigation into the health effects of smoking e-cigarettes, after nearly 100 teenagers in 14 states reported lung illnesses related to vaping.
When did e-cigarettes start?
E-cigarettes first appeared on the market in 2007 and in the years since, vaping among teens has skyrocketed. The CDC estimates that one in five high school students use e-cigarettes. From 2017 to 2018, e-cigarette use among teenagers increased by more than 75 percent, prompting the US Surgeon General to call it an “epidemic.”
Does vaping cause hypertension?
The researchers also found that vaping reduced the amount of oxygen in the blood by 20 percent, and made the walls of the blood vessels more rigid and stiff—a symptom often associated with cardiovascular diseases like hypertension and stroke.
Is vape juice toxic?
But while the long-term impact of this research is unknown, it does add to a growing body of evidence on the harms of e-cigarettes. Some studies have shown that vape juice is chemically unstable and that while the cartridges sit on the shelf, reactions in the liquid can create toxic chemicals.
Does vaping affect the vascular system?
Inhaling e-cigarette vapor alone had an immediate, negative impact on the vascular systems of first-time vapers.
Does smoking e-cigarettes affect the vascular system?
So a study out Tuesday in the journal Radiology comes not a moment too soon. In it, researchers show that inhaling e-cigarette vapor—just the vapor, without any nicotine or flavorings —has an immediate, negative impact on the vascular system. E-cigarettes first appeared on the market in 2007 and in the years since, ...
How long does vaping affect platelets?
Electronic Cigarette vaping for four months, has a neutral effect on platelet aggregation of healthy smokers. Continuation of tobacco cigarette smoking further deteriorates platelet function during 4 months of use.
How long does it take for arterial stiffness to improve after vaping?
In our study, we found that arterial stiffness, as measured by pulse wave velocity, was improved after switching to vaping for four months. On the other hand, in smokers who continued smoking, arterial stiffness was further deteriorated after four months.
Does vaping affect platelet elasticity?
However, the effects of long-term vaping on arterial elasticity have not been fully investigated. Thus, in the present study we hypothesized that vaping would have less detrimental effect on platelet and vascular function than smoking during a mid-term period of 4 months.
Is smoking a risk factor for cardiovascular disease?
Smoking is a major risk factor for cardiovascular disease. Smoking cessation delays progress of coronary artery disease and protects from recurr ence ( WHO, 2002 ). Recently, the use of electronic cigarette (e-cig) has become very popular, as it is considered product of less harm, compared to conventional tobacco cigarette (con-cig). However, studies suggest that vaping may deteriorate endothelial function to a similar extent as smoking ( Schweitzer et al., 2015; Hua and Talbot, 2016; Martin et al., 2016 ).
Does vaping cause oxidative stress?
Indeed, studies have shown that smoking-induced oxidative stress may contribute to impairment of arterial wall properties ( Carnevale et al., 2016) and that vaping cause a less increase of oxidative stress compared to smoking acutely ( Biondi-Zoccai et al., 2019 ).
How does smoking affect your blood?
Smoking and Anemia: How the Habit Affects Your Blood. When a person smokes, thousands of harmful chemicals enter the lungs. These chemicals are absorbed into the blood and carried over to the different parts of the body. Obviously, the blood is one of the first things to have close contact with such toxic chemicals and byproducts ...
What causes aplastic anemia?
In most cases, the cause of the condition is unknown. Nonetheless, it is clear that bone marrow damage , which disables the marrow to function normally, is behind aplastic anemia. According to studies, some acquired cases involve exposure to radiation, chemotherapy, toxic chemicals, being infected with certain diseases such as Epstein-Barr, hepatitis, parvovirus B19, HIV, and cytomegalovirus. Autoimmune conditions like rheumatoid arthritis and lupus are also preconditions for aplastic anemia.
What are the symptoms of hemolytic anemia?
There are many types of hemolytic anemia, with symptoms such as abdominal pain, jaundice, leg pain and ulcers, dizziness, shortness of breath, pale skin, chest pain, and cold hands and feet. Acquired hemolytic anemia means that the body is capable of producing normal red blood cells that are eventually destroyed by certain infections, diseases, ...
What is anemia in blood?
Anemia is an abnormal condition of the blood showed by low levels of hemoglobin, red blood cells, or hematocrit. These three blood parameters define the effectiveness of the blood in carrying sufficient oxygen to different body tissues. As a direct result of the decrease in the number of any or all of the three, ...
Does smoking affect pregnancy?
Smoking during pregnancy does not only affect the unborn fetus but also lowers folic acid levels in the body. This may likewise cause anemia. A research authored by Rathavuth Hong in 2006 showed that young children aged 0-35 months have higher risks of anemia due to second-hand smoke.
Does smoking cause anemia?
Smoking causes significant reduction of vitamin C in the body, which is essential in the absorption of iron. Smoking causes gastritis and ulcers, which may result in bleeding, which can cause anemia. Smoking interferes with fertility and menstrual cycles, and may cause abnormally excessive bleeding during your period.
What happens when platelets are activated?
When platelets are activated inappropriately, they stick to the lining of arteries (the endothelium) and tear it up. When a blood clot floating around in your blood stream blocks an artery in your heart it causes a heart attack; when it blocks an artery in your brain is causes a stroke.
Does smoking cause heart disease?
When platelets are activated inappropriately, they stick to the lining of arteries (the endothelium) and tear it up. When a blood clot floating around in your blood stream blocks an artery in your heart it causes a heart attack; when it blocks an artery in your brain is causes a stroke.# N#Sara Hom and colleagues at the State University of New York, recently published “ Platelet activation, adhesion, inflammation, and aggregation potential are altered in the presence of electronic cigarette extracts of variable nicotine concentrations, ” which exposed human blood platelets to extracts from conventional cigarette smoke and e-cigarette aerosol. They found that both stimulated platelet activation and that this effect is due to the ultrafine particles in both, not the nicotine.#N#They sum their results up nicely in their paper:
Does smoking cigarettes increase platelet activation?
Tobacco smoke extracts prepared from both mainstream and sidestream smoking have been associated with heightened platelet activation, aggregation, adhesion, and inflammation. Conversely, it has been shown that pure nicotine inhibits similar platelet functions.
