Many people swapped cigarettes for a vape believing the switch removes the risk. The device feels cleaner and smells better. That trade, however, is not free of consequences for the body.
What follows examines what the data say about vaping and the heart, and about a topic rarely raised in the same breath: erectile function. The question is what happens to circulation, to blood pressure, and to sexual life after the cigarette disappears and the vape appears.
The short answer is that the largest dataset available shows no significant rise in heart failure among exclusive vapers, and no protection either. In a 2025 study in Nicotine & Tobacco Research, 249,190 people in the US All of Us programme were followed for 3.7 to 3.9 years. Exclusive e-cigarette use carried a heart failure hazard ratio of 0.82.

The same analysis reported that high blood pressure was not significant overall, at 1.01, but reached 1.39 among people aged 30 to 70, which is 39% higher risk. Chronic obstructive pulmonary disease came in at 2.29, more than double. Cigarette smoking and dual use, meaning both cigarettes and vapes, were strongly linked to all outcomes; dual use had a hazard ratio of 2.18 for atherosclerotic cardiovascular disease. The follow-up lasted under 4 years and the design was observational.
A confidence interval that crosses 1 means no significant difference was seen between the groups. The interval of 0.47 to 1.41 for heart failure in exclusive e-cigarette users includes 1, so the result cannot rule out either benefit or harm. It is not evidence that vaping protects the heart.
Why Do Studies on Vaping and the Heart Disagree?
Studies disagree because populations, outcome definitions, follow-up length, and exposure measurement differ. A 2025 narrative review in Cardiology in Review reports that preliminary All of Us data raised a possible link between vaping and heart failure with preserved ejection fraction, whereas the national PATH study from 2013 to 2019 found no significant link between exclusive vaping and cardiovascular events.
That review notes that heart failure affects about 6.2 million US adults. It lists possible mechanisms: nicotine-driven disruption of the nervous control of heart rhythm, oxidative stress, inflammation, dysfunction of the inner lining of blood vessels, and scarring of heart muscle. The limitations are few long-term studies, difficulty measuring exposure, and confounding. The review recommends a precautionary approach, especially for people who have or are at risk of heart failure.
Vaping and Erections; Why Are the Heart and Sex Life Linked?
The link runs through blood vessels. A 2021 study in the American Journal of Preventive Medicine used the national PATH study from 2016 to 2018 and examined men aged 20 and over. Erectile dysfunction prevalence was 20.7% in the full sample and 10.2% among men aged 20 to 65 without heart disease.
Daily vapers made up 2.1% of the full sample. Daily users, compared with never users, had 2.24 times the odds of reporting erectile dysfunction, and 2.41 times among men aged 20 to 65 without heart disease. Physical activity was linked to lower odds of erectile dysfunction, with odds ratios of 0.44 to 0.58. The study was cross-sectional, so it cannot show causation, and erectile dysfunction was self-reported. In my therapy room I meet men who come in for erection problems and never list vaping among their habits, because they consider it harmless. When I ask about their day, the device almost never leaves their hand. Talking about this habit, without blame, is often the first real step of treatment. An erection depends on healthy blood vessels: adequate blood flow, an intact inner lining, and coordinated nerve signalling.
If You Swapped Cigarettes for a Vape, What Is the Next Step?
For someone who has already quit cigarettes, the useful next step is to plan the end of vaping and to keep the body moving. Data from the All of Us programme showed that cigarette smoking and dual use were strongly linked to all outcomes, and dual use had a hazard ratio of 2.18 for atherosclerotic cardiovascular disease.

Our position is clear: for someone who has quit cigarettes, a vape can be an exit ramp, not a permanent home; and using cigarettes and vapes together is the worst combination of all. [Needs further verification: no data with ten years of follow-up on exclusive e-cigarette use and heart failure has been published yet.] Physical activity was linked to lower odds of erectile dysfunction, with odds ratios of 0.44 to 0.58 among men aged 20 and over in the PATH analysis, so movement belongs alongside a clear end date for the device. The decision about how to stop belongs with the person and their clinician.
The largest dataset available shows no significant link between exclusive vaping and heart failure. The hazard ratio of 0.82 carried a confidence interval of 0.47 to 1.41, which crosses 1. Follow-up lasted under 4 years, so longer-term answers remain unknown.
Is vaping safer than smoking cigarettes?
For heart failure, exclusive vaping showed a hazard ratio of 0.82 with a confidence interval of 0.47 to 1.41 in the All of Us analysis, while cigarette smoking and dual use were strongly linked to all outcomes. Dual use reached a hazard ratio of 2.18 for atherosclerotic cardiovascular disease.
Can vaping affect erections?
In the PATH analysis from 2016 to 2018, men aged 20 and over who vaped daily had 2.24 times the odds of reporting erectile dysfunction compared with never users, and 2.41 times among men aged 20 to 65 without heart disease. The cross-sectional design cannot establish causation.
Does physical activity matter for erectile function?
Physical activity was linked to lower odds of erectile dysfunction, with odds ratios of 0.44 to 0.58 in the same national PATH study of men aged 20 and over. The result is an association, not proof, but movement is a low-risk addition to any plan.
Conclusion; What Should You Do for Your Heart and Your Relationship?
Quitting cigarettes is a large step, and the evidence base on vaping is still short, with follow-up under 4 years in the main analysis. Letting go of the vape and moving more are changes that sit within reach. Neither requires a specialist to begin. The heart and the blood vessels that support sexual function respond to the same daily choices, and those choices can start today.
