ISLAMABAD, MARCH 15 (ONLINE): The American Heart Association\u2019s Life\u2019s Simple 7 is a roadmap of seven modifiable risk factors for heart disease.
\nCardiovascular disease is a known risk factor for neurodegenerative diseases such as Alzheimer\u2019s disease and dementia.
\nA new study has found a link between higher Life\u2019s Simple 7 scores for cardiovascular health in older adults and a potential decrease in biomarkers for neurodegenerative diseases.
\nThe researchers note that promoting better cardiovascular health could be particularly beneficial to Black and African American populations who have a higher risk of cardiovascular disease
\nIn 2010Trusted Source, the American Heart Association launched its Life\u2019s Simple 7 Journey to HealthTrusted Source \u2014 a roadmap of seven known lifestyle risk factors for cardiovascular disease that are modifiable, such as smokingTrusted Source, diet, and body mass index (BMI).<\/p>\n
Past studies show that those who follow Life\u2019s Simple 7 may lower their risk for heart failure, coronary heart disease, hypertension, atherosclerotic cardiovascular disease, and cardiovascular disease in cancer survivorsTrusted Source.<\/p>\n
Cardiovascular disease is also a known risk factor for developing neurodegenerative diseases such as Alzheimer\u2019s disease and dementia.<\/p>\n
In a new study, researchers found a link between having higher Life\u2019s Simple 7 scores for cardiovascular health in older adults and a potential decrease in biomarkers for neurodegenerative diseases. They also note that increased heart disease education could be particularly beneficial for members of the Black and African American community, who have a higher risk of both cardiovascular disease and dementia.<\/p>\n
The findings were recently published in the journal JAMA Network OpenTrusted Source.<\/p>\n
\u201cNeurodegenerative diseases, such as Alzheimer\u2019s disease and related dementias, are the most disabling disorders in older adults, with a significant burden on individuals and caregivers,\u201d Anisa Dhana, MD, MSc, a postdoctoral research fellow for the Rush Institute for Healthy Aging at Rush University Medical Center in Chicago, and corresponding author of the study told Medical News Today. \u201cResearch focused on the prevention of Alzheimer\u2019s could have a great public health impact.\u201d<\/p>\n
\u201cThe American Heart Association\u2019s Life\u2019s Simple 7 is a well-established tool for promoting cardiovascular health, which has been strongly linked to lower risks of cardiovascular disease and stroke,\u201d Dhana continued. \u201cSince cardiovascular disease and dementia share common risk factors, we aimed to investigate the role of Life\u2019s Simple 7 in the neurodegeneration process.\u201d<\/p>\n
What is Life\u2019s Simple 7?
\nFor this study, researchers recruited more than 1,000 adults ages 65 and over from the Chicago Health and Aging Project. More than half of the participant pool identified as Black or African American.<\/p>\n
Study participants received points based on which components of Life\u2019s Simple 7 they met, including:<\/p>\n
Eating a healthy diet
\nRegular exercise
\nHealthy BMI
\nNon-smoking status
\nAbsence of dyslipidemia, diabetes, and hypertension
\nThey were then divided into three groups based on their cardiovascular health (CVH) score: 0-6 points, 7-9 points, and 10-14 points.<\/p>\n
Higher CVH scores linked to lower NfL biomarker
\nUpon analysis, researchers found that participants with the highest CVH scores had significantly lower serum levels of a neurodegeneration biomarker called neurofilament light chain (NfL). Additionally, those with high CVH scores experienced slower annual increase in NfL levels as participants aged.<\/p>\n
\u201cNfL is a protein found in nerve cells that helps keep them strong and healthy,\u201d Dhana explained. \u201cWhen these cells are damaged, NfL is released into the blood and spinal fluid, making it a useful marker of brain health. We used NfL in our study because higher levels may indicate nerve cell damage, helping us understand the potential link between cardiovascular health and neurodegeneration.\u201d<\/p>\n
\u201cThese results highlight the importance of maintaining good CVH through managing risk factors, as it may help reduce the risk of neurodegenerative diseases like Alzheimer\u2019s,\u201d she added.<\/p>\n
Need for increased heart disease education in the Black community
\nDhana and her team also observed that participants with the highest CVH scores were predominantly White.<\/p>\n
Researchers believe this suggests that promoting cardiovascular health education in older adults, especially in the Black community, may help lighten the burden of neurodegenerative diseases.<\/p>\n
Past research shows that Black individuals have an increased risk for both cardiovascular and neurodegenerative diseases.<\/p>\n
\u201cImproving cardiovascular health in older adults may help reduce the impact of neurodegenerative diseases, particularly in Black adults, who experience higher rates of cardiovascular disease. These findings emphasize the need for greater awareness and access to cardiovascular health resources in communities with largely Black individuals.\u201d

\u201cWe plan to further explore the link between cardiovascular health and neurodegeneration by examining additional biomarkers directly related to brain pathology, such as amyloid-betaTrusted Source. Future research may evaluate the success of interventions (e.g., diet and physical activity interventions) in reducing biomarkers of neurodegeneration levels, such as NfL,\u201d Dhana said.<\/p>\n
Controlling heart disease risk factors important
\nMNT had an opportunity to speak with Cheng-Han Chen, MD, a board certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center in Laguna Hills, CA, about this study.<\/p>\n
\u201cThis study reaffirms the importance of following the American Heart Association\u2019s Simple 7 guidelines to help control cardiovascular risk factors,\u201d Chen commented. \u201cIn particular, this study supports previous research that has found an association between cardiovascular health and neurological health, specifically by controlling the future risk of dementia.\u201d<\/p>\n
\u201cAs our population continues to age, we will continue to see higher and higher rates of neurodegenerative disease in our population, which then results in a significant health burden to our society,\u201d he continued. \u201cIf we\u2019re able to lower the prevalence of neurodegenerative diseases such as dementia, we can potentially significantly improve the overall health of our elderly population.\u201d<\/p>\n
\u201cTraditionally medically underserved communities such as (the) Black population face a particular burden from neurodegenerative diseases. This research supports a need to reach out to these communities in order to improve their health outcomes.\u201d

Mechanism for heart\/brain disease may overlap
\nMNT also spoke with Jason Tarpley, MD, PhD, a board certified vascular neurologist and medical director of the Pacific Stroke and Neurovascular Center at Providence Saint John\u2019s Health Center in Santa Monica, CA, about this research.<\/p>\n
\u201cWe used to think that neurodegenerative diseases like Alzheimer\u2019s disease and other dementia illnesses were genetic-basedTrusted Source, and then there are other diseases like stroke and heart attack, which are more related to cardiovascular risk factors,\u201d Tarpley explained. \u201cBut over the years, we\u2019ve really recognized that there\u2019s a lot of overlap. I think this study is pretty interesting in the sense that it gives a potential mechanism by which that may happen.\u201d<\/p>\n
\u201cI would love to see a prospective study that would look at a high risk population and see if improving CVH scores lowered biomarkers and decreased risk of developing neurodegeneration,\u201d\u00a0he\u00a0added.<\/p>\n","protected":false},"excerpt":{"rendered":"
