Here’s How E-Cigarettes Can Be More Dangerous For Heart Health

Researchers have found that electronic nicotine delivery systems, such as E-Cigarettes might be just as harmful to the heart, than traditional cigarettes.

“Our results suggest that e-cigarette use is associated with coronary vascular dysfunction at rest, even in the absence of physiologic stress, these findings indicate the opposite of what e-cigarette and vaping marketing is saying about their safety profile,” said study researcher Susan Cheng, Director of Public Health Research at the Smidt Heart Institute.

A recent study by the US Food and Drug Administration found that 27.5 per cent of high school students used e-cigarettes in 2019, as compared to 20.8 per cent in 2018.

The study also estimates that in 2018, around 3.62 million middle and high school students were e-cigarette users.

For the current findings, the team of researchers compared healthy, young adult smokers aged 18 to 38 who were regular users of e-cigarettes or tobacco cigarettes.

The researchers then measured participants’ blood flow to the heart muscle – focusing on a measure of coronary vascular function – before and after sessions of either e-cigarette use or cigarette smoking, while participants were at rest and also after they performed a handgrip exercise which simulates physiologic stress.

It was also found that in smokers who had inhaled the traditional cigarettes, blood flow increased modestly and then decreased with subsequent stress.

However, in smokers who used e-cigarettes, blood flow decreased after both inhalation at rest and handgrip stress.

“We have known for decades that smoking increases your risk for heart attack and dying from heart disease, now, with this study, we have compelling evidence suggesting that newer methods of electronic nicotine delivery may be equally, or potentially more, harmful to your heart as traditional cigarettes,” said researcher Christine Albert.

Given that e-cigarettes represent a relatively new product in the market, Albert cautions users that there may be a number of unforeseen health effects.

To better understand the potentially dangerous consequences of e-cigarettes, investigators plan on studying the mechanisms underlying changes in heart and blood vessel flow seen in their work to-date, as well as the effects of e-cigarette use across a more diverse population of study participants including those with existing cardiovascular risk.

“What we are learning from our own research, along with the work of others, is that use of any electronic nicotine delivery system should be considered with a high degree of caution until more data can be gathered,” said study senior author Florian Rader.

The findings were presented at the annual American Heart Association Scientific Sessions 2019. (IANS)

Children of Mothers With Diabetes Are Likely To Suffer From Heart Diseases, Says Study

The researchers also found higher rates for specific types of CVD children of mothers with diabetes

Children of mothers with diabetes have increased rates of early onset cardiovascular disease or CVD (conditions affecting the heart or blood vessels) from childhood up to the age of 40, the researchers have warned.

The increased rates were more pronounced among children of mothers with a history of CVD or diabetic complications, said the study published in the journal The BMJ.

“Our study provides evidence that children of mothers with diabetes, especially those with a history of CVD or with diabetic complications, had increased rates of early onset CVD throughout the early decades of life,” said study researchers from Aarhus University in Denmark.

If this association is shown to be causal, preventing, screening, and treating diabetes in women of childbearing age could be important not only for improving the health of the women but also for reducing long term risks of CVD in their offspring, the researchers added

The number of women diagnosed with diabetes before or during pregnancy has increased globally, and children of these women are more likely to have risk factors for future CVD, such as high blood pressure and high blood sugar levels. It is unclear, however, whether or to what extent exposure to diabetes in the womb increases the risk of developing CVD in offspring over a lifetime.

So an international team of researchers set out to evaluate associations between diabetes diagnosed before or during pregnancy and early onset CVD in children during their first four decades of life. They base their findings on national registry data for over 2.4 million children born without congenital heart disease in Denmark from 1977 to 2016.

Diabetes was categorised as pregestational (before pregnancy) or gestational (during pregnancy) and women with diabetic complications were identified.

Other potentially influential factors, such as mother’s age, education, lifestyle and medical history were also taken into account. During up to 40 years of follow-up, children of mothers with diabetes had a 29 per cent increased overall rate of early onset CVD compared with children of mothers who did not have diabetes (cumulative risks: 17.8 per cent vs 13.1 per cent ).

The researchers also found higher rates for specific types of CVD children of mothers with diabetes, particularly heart failure (45 per cent), hypertensive disease (78 per cent), deep vein thrombosis (82 per cent), and pulmonary embolism (91 per cent).

Increased rates were seen in each age group in childhood (before 20 years of age) and early adulthood (from 20 to 40 years of age), regardless of the type of diabetes they were exposed to (pregestational or gestational) and rates were similar for both type 1 and type 2 diabetes, the study said.
