Roundup: HPV Virus May Increase Risk of Heart Disease; and More News

New Research Links HPV to Increased Risk of Heart Disease

Human papillomavirus (HPV), a virus known for causing several types of cancer, may also significantly increase the risk of heart disease and coronary artery disease (CAD), according to a new study presented at the American College of Cardiology’s Annual Scientific Session.

HPV is the most common sexually transmitted infection in the U.S., and certain strains of the virus are known to cause cervical cancer. The virus is responsible for nearly all cervical cancer cases, which makes vaccination efforts critical in the fight against this preventable cancer. Most head and neck cancers were found in patients who smoked -- but an increase in cases in recent years is due to the proliferation of HPV, experts say.

While the link between HPV and cancer has been well established, emerging evidence suggests that the virus may also pose a threat to cardiovascular health.

The study, which represents the largest analysis of its kind, pooled data from several global studies, including nearly 250,000 patients. It provides compelling evidence that HPV is more than just a cancer risk factor. The findings underscore the need for further research into the connection between HPV and cardiovascular health.

The concept that HPV could be linked to heart disease is a relatively new development in the medical field. Stephen Akinfenwa, M.D., an internal medicine resident at UConn School of Medicine and the lead author of the study, emphasized the importance of this discovery.

“Our study shows that clearly there is an association of some kind between HPV and cardiovascular disease,” he stated in a news release. “The biological mechanism has not been determined but is hypothesized to be related to chronic inflammation. We would ultimately like to see if reducing HPV via vaccination could reduce cardiovascular risk.”

The study indicates that HPV-positive individuals face a significantly higher risk of developing cardiovascular issues -- compared to those who do not carry the virus. The research examined seven cohort studies, conducted between 2011 and 2024, which tracked cardiovascular outcomes among individuals with known HPV status over a period ranging from three to 17 years. These studies included participants from the United States, South Korea, Brazil, and Australia.

The analysis revealed concerning results: individuals with HPV had a 40 percent higher likelihood of developing cardiovascular disease, compared to those without the virus. Furthermore, they were found to be twice as likely to develop coronary artery disease, a condition where plaque builds up in the arteries, reducing blood flow to the heart. The relationship between HPV and heart disease remained strong, even after adjusting for other known risk factors such as smoking, diabetes, and family history of heart disease.

Although no significant connection was found between HPV and high blood pressure, the overall impact on cardiovascular health was profound. These findings highlight a crucial point — about 20 percent of cardiovascular disease cases cannot be explained by conventional risk factors such as smoking, obesity, and hypertension. This gap makes it essential to explore non-traditional risk factors like HPV that may play a role in heart disease.

Given the findings of this study, Dr. Akinfenwa suggested that clinicians may want to consider closer cardiovascular monitoring for patients who test positive for HPV, much as they would for individuals with other established risk factors.

“We always talk about cardiovascular risk factors like smoking, high blood pressure and so on, but we know that about 20 percent of cardiovascular disease cannot be explained by these conventional risk factors,” he stated. “This makes it important to identify non-conventional risk factors like HPV that could potentially be targeted.”

For health consumers, this study signals the importance of staying informed about the broader implications of HPV infection. The findings also raise questions about the potential role of HPV vaccination in preventing cardiovascular issues.

Currently, the U.S. Centers for Disease Control and Prevention (CDC) recommends that all children and teens receive the HPV vaccine to prevent cancers associated with the virus. However, many U.S. adults have missed the opportunity to get vaccinated, as the vaccine became available after the recommended age for some individuals. Given the study’s results, a discussion about extending vaccination recommendations to older populations may be warranted.

Daily Physical Activity – Even of Light Intensity -- Linked to Lower Cancer Risk

A new study conducted by researchers at Oxford Population Health adds to the mounting evidence related to health benefits of regular exercise. The study, published in the British Journal of Sports Medicine, finds that even light-intensity physical activity — such as casual walking, shopping, and household chores — can significantly reduce the risk of cancer.

The research challenges the lingering notion that only intense physical exercise can deliver health benefits.

The study utilized data from the UK Biobank, involving 85,394 participants with a median age of 63. These individuals wore wrist-based activity trackers for one week, which captured data on their daily activity levels, intensity, and step counts. Over the course of an average follow-up period of 5.8 years, researchers tracked the cancer diagnoses of 2,633 participants, providing a robust analysis of how varying levels of physical activity influence cancer risk.

One of the most striking findings is that the total number of steps taken daily had a greater impact on cancer risk than the intensity of the activity. Participants who engaged in the highest levels of daily physical activity had a 26 percent lower risk of developing cancer compared to those with the lowest activity levels.

While both light-intensity activities (such as walking at a leisurely pace) and more vigorous exercise contributed to a reduction in cancer risk, the research also highlighted that higher step counts—rather than faster or more intense steps—were associated with the greatest benefits.

Specifically, individuals who walked 7,000 steps per day experienced an 11 percent reduction in cancer risk, compared to those who took only 5,000 steps per day. Those who reached 9,000 steps per day had a 16 percent lower risk of developing cancer.

In a news release, Aiden Doherty, professor of Biomedical Informatics at Oxford Population Health and senior author of the study, said: "Our research highlights the importance of all forms of movement. Whether it’s increasing daily steps, engaging in light activity, or incorporating moderate-to-vigorous exercise, any level of physical activity appears to contribute to lower cancer risk."

While the study found that sedentary behavior alone was not directly linked to an increased cancer risk, the data underscored the importance of replacing sedentary time with physical activity. The risk of cancer was lower in those who incorporated even minimal physical movement throughout their day, emphasizing that small changes to reduce sedentary behavior could have a profound impact on health outcomes.

Sleep Quality Linked to Advanced CKM (Cardiovascular-Kidney-Metabolic) Syndrome

New research focuses on the significant role sleep quality may play in the progression of cardiovascular-kidney-metabolic (CKM) syndrome, a complex health condition linked to obesity, Type 2 diabetes, chronic kidney disease, and various cardiovascular diseases.

According to the new study, published in the Journal of the American Heart Association, individuals with better sleep quality were less likely to experience the advanced stages of CKM syndrome.

The study, conducted by researchers at the General Hospital of Northern Theater Command in Shenyang, China, examined the relationship between sleep and the progression of CKM syndrome in U.S. adults.

It analyzed data from the National Health and Nutrition Examination Survey (2015-2020) involving 10,607 participants, with an average age of 49 years. The findings suggest that improving sleep quality may serve as a modifiable lifestyle factor that could potentially reduce the risk of advancing to the later stages of CKM syndrome.

CKM syndrome is a multifaceted health disorder that encompasses a range of interconnected conditions, including obesity, Type 2 diabetes, chronic kidney disease, and various forms of cardiovascular disease such as heart failure, atrial fibrillation, and stroke. The condition is prevalent in individuals who are at risk for cardiovascular disease or already living with it.

According to the American Heart Association, approximately one in three adults in the U.S., or about 89 million people, have multiple risk factors for CKM syndrome. These risk factors include obesity, high blood pressure, high cholesterol, elevated blood glucose, and abnormal triglyceride levels. Sleep disorders, which are increasingly recognized as a contributing factor, have been linked to the progression of CKM syndrome, though the exact relationship between the two remains an area of active research.

The study examined five key sleep behaviors: sleep duration, difficulty falling asleep, daytime sleepiness, snoring, and nocturia (the need to wake up during the night to urinate). Researchers compared these sleep quality indicators with the five stages of CKM syndrome, which range from no risk factors (Stage 0) to advanced cardiovascular disease (Stage 4).

Study participants with moderate to high sleep quality were found to be less likely to be in the advanced stages of CKM syndrome (Stages 3 or 4) compared to those with poor sleep quality. However, the researchers cautioned against assuming a direct cause-and-effect relationship between poor sleep and advanced disease.

Brendan Everett, M.D., an associate professor at Harvard Medical School, noted in a press release that the study was cross-sectional, meaning it captured data at a single point in time rather than over a prolonged period. "This study can say zero about any directional causality between sleep and metabolic disease," he explained. "You can't say that one thing comes before the other."

It’s also possible, he pointed out, that advanced stages of CKM syndrome might contribute to poor sleep, rather than the other way around.
