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

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

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)

Global Warming Can Make You Fall ill More Often: Study

The study said that increased heat may cause illness through undernourishment in a number of ways: reducing appetites, provoking more alcohol consumption, reducing motivation or ability to shop and cook and exacerbate any undernutrition

Global Warming is likely to increase illnesses caused by undernutrition, due to the effects of heat exposure, researchers have warned.

For the study published in the journal PLOS Medicine, the researhers analysed daily hospitalisation data covering almost 80 per cent of Brazil between 2000 and 2015.

They studied the link between daily mean temperatures and hospitalisation for undernourishment according to the International Classification of Diseases.

“The association between increased heat and hospitalisation for undernutrition was greatest for individuals aged over 80, and those 5 to 19 years,” said the researchers from Monash University, Australia.

The researchers found that for every 1 degree Celsius increase in daily mean temperature during the hot season, there was a 2.5 per cent increase in the number of hospitalisations for undernutrition.

“We estimated that 15.6 per cent of undernutrition hospitalisations could be attributed to heat exposure during the study period,” said study’s lead author Yuming Guo.

“Climate change is one of the biggest threats to the reduction of hunger and undernutrition, especially in low and middle-income countries. It has been estimated that climate change will reduce global food availability by 3.2 per cent and thus cause about 30,000 underweight-related deaths by 2050,” the report said.

“It is plausible to speculate that climate changes could not only increase the rate of undernutrition in the most affected areas of the globe, but at the same time, impair individuals’ capacity to adapt to projected rises in temperature,” said the researchers. (IANS)
