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.
Does vaping affect platelet function?
Switching from smoking to vaping for four months has a neutral effect on platelet function, as assessed by Light Transmission Aggregation and PFA-100, while it improves arterial stiffness, as evaluated by PWV. Conversely, continuation of smoking for four months further deteriorates platelet and vascular function markers.
What factors increase the risk of platelet disorders in smokers?
Changes in platelet count, morphology and platelet activation enhance the risk. Material and methods: The objective of the study was to assess platelet parameters in smoking healthy subjects with reference to sex.
Does vaping affect endothelial function like smoking?
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 ). Platelets activation is an important mechanism in cardiovascular disease and progression ( Rubenstein et al., 2004 ).
What are the causes of high platelet count?
Inflammatory conditions like autoimmune diseases, cancer or trauma, as well as certain infections and iron deficiency, are common causes of a high platelet count. Treatment is directed at the stimulus, and the platelet count returns to normal once resolved.
What happens when platelets are activated?
Does smoking cause heart disease?

Does vaping cause anemia?
Chronic (long-term) inhalation exposure has caused various disorders in the blood, including reduced numbers of red blood cells and aplastic anemia, in occupational settings.
Is vaping worse than smoking?
The problem is that there are big health risks with both habits. Both smoking and vaping involve nicotine, which is very addictive. Smoking has been proven to cause cancer, which can kill you. But vaping has been proven to cause serious lung illness, which can also kill you.
Does nicotine thicken your blood?
Nicotine is known to increase levels of hormones such as adrenaline in the body, which in turn can increase the formation of blood clots. Dr Lyytinen said: “Our results suggest that using e-cigarettes that contain nicotine have similar impacts on the body as smoking traditional cigarettes.
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.
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.

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 ).
What is elevated platelet count?
In general, a platelet count more than 450,000 cells per microliter is considered elevated; this is known as thrombocytosis. There are numerous causes of thrombocytosis and fortunately, the majority are benign and transient. Let's review some of the most common causes.
What cancers have elevated platelets?
This is more common in solid tumors like lung cancer, hepatocellular (liver) carcinoma, ovarian cancer, and colorectal cancer. Elevated platelet count can also be seen in chronic myelogenous leukemia (CML) .
What causes blood clots in et?
With these conditions, the excessive numbers of platelets cause the blood to be thick and flow more slowly which may result in blood clots. Treatment is aimed at reducing the platelet count to reduce this risk. 2 .
What causes thrombocytosis in the bone marrow?
Chronic myleoproliferative disorders (disorders where the bone marrow makes too many blood cells) can cause thrombocytosis. These include polycythemia vera, essential thrombocythemia (ET), 1 and primary myelofibrosis. In ET, for example, the bone marrow makes too many megakaryocytes, the cells that make platelets, resulting in thrombocytosis.
What are the most dangerous complications of thrombocytosis?
The most dangerous complication for most people with thrombocytosis is blood clots. Pregnant women also may have serious complications that include miscarriage, slowed fetal growth, or placental abruption. 10
What causes thrombocytosis?
Conditions with inflammation, like rheumatologic disorders, inflammatory bowel disease, and vasculitides, can have thrombocytosis. 5 The elevated platelet count occurs in response to cytokines (small proteins released from cells that signal other cells to do something). In particular, the cytokines interleukin-6 and thrombopoietin stimulate platelet production.
Can cryoglobulinemia cause platelet elevation?
Mixed cryoglobulinemia can cause a false elevation in the platelet count. 6 In this condition, cryoglobulins (proteins) in the blood stick together when exposed to cold temperatures (like the hands and feet).
How do e-cigarettes affect neutrophils?
A new study published in the Journal Cell Physiology shows that e-cigarettes have toxic effects on neutrophils function, making them a threat to human health by increasing the likelihood of infection with Gram-negative bacteria. E-cigarettes are in wide use today, among 7% to 12% of adults and up to 37% of teenagers/new adults.
What is the role of e-cigarette smoke in the neutrophil attack?
They were also partially disarmed by e-cigarette smoke, which reduced reactive oxygen species (ROS) production within the immune cells by 48%. ROS are at the heart of neutrophil attack by what biologists call the neutrophil extracellular trap (NET). These fascinating antibacterial weapons are structures created from DNA strands coated with sticky proteins or peptides that fight microbes.
What is the purpose of vaping liquids?
The researchers used commercial vaping liquids and a commonly used vaping device to expose batches of neutrophils in culture to fresh puffs of e-cigarette vapor. They also injected Pseudomonas into healthy mice, exposed them to e-cigarette smoke over the long term and examined neutrophil migration as well as bacterial load.
How many fold reductions in chemotaxis in human neutrophils exposed to e-cigarette vapor?
Neutrophils in culture. The researchers found a 4-fold reduction in chemotaxis in human neutrophils exposed to e-cigarette vapor. Normally, their attraction to Gram-negative bacteria occurs in response to the cell wall component f-Met-Leu-Phe.
Is vaping safe?
Vaping – not a safe alternative. E-cigarettes have become a topic of hot controversy, with some people arguing their safety vis-à-vis conventional cigarettes, and others pointing out the almost complete lack of knowledge regarding the safety of inhaled chemicals in e-cigarette smoke, and their physiological effects.
Can e-cigarettes affect endothelial cells?
Their RNA sequencing studies on lung tissue from these animals also show that endothelial cells may be impacted by the e-cigarette vapor, such that they have a lower production of proteins that stimulate the passage of leukocytes out of the blood vessel into the infected site.
Is it safe to smoke e-cigarettes?
E-cigarettes are in wide use today, among 7% to 12% of adults and up to 37% of teenagers/new adults. While touted as a safer alternative to conventional smoking, evidence shows that they can be extremely harmful and in fact, lethal, as the recent spate of vaping-linked deaths in America shows.
What does it mean when your platelets are high?
In secondary thrombocytosis, high platelets occurs as a symptom of another disease or condition, such as anemia, infection or cancer. In many cases, high platelets may not produce specific symptoms. In other cases, the elevation in platelet levels leads to the development of unwanted and unnecessary blood clotting throughout the body, ...
How to identify high platelets?
A high platelet count can be identified through routine blood tests. The occurrence of high platelets is divided into two medical categories: primary thrombocythemia and secondary thrombocytosis. In primary thrombocythemia, the cause of the high platelets is not known, and it occurs as an independent condition.
What other symptoms might occur with high platelets?
High platelets may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. However, some people who have high platelets may not experience any other symptoms. In these individuals, high platelets may only be detected through routine blood tests.
What is high platelet count?
High platelets is a condition in which the blood contains more platelets than normal. Platelets are small blood cell fragments that assist in blood clotting. In a healthy person, there are usually 150,000 to 450,000 platelets per microliter of blood. A high platelet count can be identified through routine blood tests.
What causes high platelets in secondary thrombocytosis?
A wide range of diseases and conditions may cause high platelets including: Anemia (low red blood cell count) Blood loss. Cancer.
What are the complications of high platelets?
Potential complications of high platelets may include: Bleeding. Blood clots. Brain damage such as stroke.
Where do blood clots form?
The extremities and the brain are common sites for blood clot formation with high platelets. Clots can also form in other organs. Blood clots in the placenta often cause pregnancy loss in pregnant women with primary thrombocythemia. Signs and symptoms of blood clotting, which may be serious or even life threatening, can include:
What drugs cause platelet dysfunction?
Drugs represent the most common cause of platelet dysfunction in our overmedicated society. While acetylsalicylic acid (aspirin), adenosine diphosphate receptor antagonists (clopidogrel and prasugrel), and integrin αIIbβ3 (GPIIb-IIIa) receptor blockers (abciximab, eptifibatide, and tirofiban) are well-known prototypes of antiplatelet drugs, ...
Is bleeding diathesis a concern?
Therefore, induction of a bleeding diathesis remains a significant concern. This is especially relevant in patients with preexisting hemostatic defects of any kind, which may remain compensated as long as platelet function (and/or coagulation) is not inhibited pharmacologically.
