Vaping has been found to increase the risk of heart failure by nearly 20%, according to a new study. The research analyzed data from over 175,667 participants in the US and found that those who used e-cigarettes were almost a fifth more likely to develop heart failure compared with people who had never used them.
Heart failure is a condition where the heart becomes too stiff or weak to pump blood as effectively as it should. More than 1 million UK adults and around 6.5million in the US suffer from its debilitating symptoms.
Researchers tracked participants over a median follow-up period of 45 months, during which time they analyzed associations between e-cigarette use and new heart failure diagnoses within that period. Within this timeframe, approximately 3,242 participants had developed heart failure. The average age of those included in the study was 52.
The difference in risk seen between e-cigarette users and nonusers was substantial. It's worth considering the consequences to your health, especially with regard to heart health.
Past research has shown that e-cigarettes may be safer than smoking regular cigarettes and can help with smoking cessation, but increasingly vaping has been found to cause similar effects on lung and cardiovascular function as smoking. However, the new study was observational, which allowed researchers to infer a relationship between e-cigarette use and heart failure but not conclusively determine a causal one.
The US surgeon general issued an advisory calling youth e-cigarette use an epidemic in 2018. In 2023, the Annual National Youth Tobacco Survey results indicated that 10% of high school and middle school students (around 2.8 million) reported use of any tobacco product, with e-cigarettes being the most commonly used form.
According to the Centers for Disease Control and Prevention, around 4.5% of Americans aged 18 and older were current e-cigarette users in 2021.
