Vaping & Heart Health: Risks, Damage & Existing Conditions
E-cigarettes and vape pens, like traditional cigarettes, deliver nicotine in a vaporized form. This nicotine intake isn’t without consequence, posing both short- and long-term risks to cardiovascular health. The addictive nature of nicotine is well-established, and its effects on the heart are increasingly understood.
Heart Rate Impacts
Increased Heart Rate
Vaping introduces a surge of nicotine into the bloodstream, triggering the release of adrenaline. This physiological response causes blood vessels to constrict and the heart to beat faster. Dr. Middlekauff notes that individuals may “feel heart palpitations” as a result.
For first-time vapers, a heart rate increase of up to 4 beats per minute is possible. While seemingly small, sustained increases can lead to an abnormal heart rate, potentially elevating the risk of heart attack and sudden death, even in those without pre-existing heart conditions. Vaping can also hinder the heart’s ability to return to a normal rate after physical exertion.
Blood Pressure Changes
The nicotine in e-cigarettes doesn’t just affect heart rate; it also elevates blood pressure. Here’s a direct result of the body’s fight-or-flight response to nicotine. Studies indicate that vaping can increase systolic blood pressure by 4 percent and diastolic blood pressure by 7 percent.
Potential for Heart Damage
Oxidative Stress and Atherosclerosis
Vaping places increased demands on the heart, requiring more oxygen for proper function. It’s also associated with increased oxidative stress, an imbalance where harmful free radicals outweigh antioxidants. According to Dr. Middlekauff, “Oxidative stress increases your risk of many diseases, including heart disease, premature aging, and cancer.”
This oxidative stress can contribute to atherosclerosis, the buildup of plaque in the arteries. While the levels of harmful chemicals like acrolein, acetaldehyde, and formaldehyde are lower in e-cigarettes compared to traditional cigarettes, Dr. Middlekauff cautions that widespread adoption of vaping could still lead to a significant number of health problems.
Vaping and Pre-Existing Conditions
Increased Risks for Vulnerable Individuals
For individuals already managing heart conditions like irregular heartbeat, high blood pressure, or existing heart disease, vaping can exacerbate these issues. Elliott Antman, MD, a professor of cardiovascular medicine at Harvard Medical School, explains that those with coronary artery blockages or congestive heart failure “could be made worse by exposure to nicotine,” potentially experiencing chest pain or worsening symptoms of heart failure.
Those with arrhythmias, such as atrial fibrillation, may also face an increased risk of episodes due to the nicotine in e-cigarettes, according to Dr. Antman.
Frequently Asked Questions
What happens to your heart rate when you vape?
When you vape, the nicotine causes your adrenaline levels to increase, leading to a faster heart rate and constricted blood vessels. First-time vapers may experience an increase of up to 4 beats per minute.
Does vaping affect blood pressure?
Yes, vaping increases blood pressure, similar to the effect of nicotine from traditional cigarettes. It can increase systolic blood pressure by 4 percent and diastolic blood pressure by 7 percent.
Can vaping cause long-term heart problems?
Early research suggests that long-term e-cigarette use can increase the risk of heart failure by 19 percent. It can also contribute to atherosclerosis and oxidative stress, increasing the risk of various diseases.
Given the emerging evidence of cardiovascular risks associated with vaping, what steps can individuals take to protect their heart health?
