A recent study published in Nature Communications has uncovered shared genetic risk factors between osteoarthritis and cardiovascular disease, suggesting a common basis for both conditions.
Understanding Osteoarthritis And Cardiovascular Disease
Osteoarthritis is one of the most common musculoskeletal disorders globally and is linked to various health issues, including cardiovascular disease. Both conditions can result from environmental factors such as aging, smoking, lack of physical activity, and obesity. In some patients, osteoarthritis and cardiovascular disease occur together, potentially due to these shared risk factors or genetic predispositions.
While certain genetic factors are known to influence both diseases, the extent to which they share a genetic basis remains unclear.
Key Findings of The Study
The study aimed to determine whether the co-occurrence of osteoarthritis and cardiovascular disease is due to shared genetic or environmental factors. Researchers analyzed data from twin studies to investigate these connections.
The analysis included 59,970 twins from 29,985 pairs. Among them, 7,363 had osteoarthritis in their hands, hips, or knees, while 13,685 had severe cardiovascular diseases such as cardiac arrhythmias, coronary heart disease, heart failure, or stroke.
The study found that osteoarthritis and cardiovascular disease are frequently diagnosed together. Concordance rates for these conditions were higher in identical twins than in fraternal twins.
The analysis revealed that much of the overlap between osteoarthritis and cardiovascular disease can be attributed to shared genetic factors that operate independently of age, sex, education level, body mass index (BMI), smoking status, and physical activity.
Interestingly, shared genetic risks were more significant for severe cardiovascular diseases associated with hip osteoarthritis compared to knee osteoarthritis. Unique environmental factors were also identified as contributors to the co-occurrence of knee osteoarthritis and severe cardiovascular diseases.
Among the specific cardiovascular conditions studied, shared genetic factors played a larger role in the co-occurrence of osteoarthritis with cardiac arrhythmia, coronary heart disease, or stroke. In contrast, unique environmental influences were more significant in the co-occurrence of osteoarthritis with heart failure; however, this finding is less clear due to a limited number of cases.
Implications of the Research
The study’s findings suggest that shared genetic risk factors may play a crucial role in the development of both osteoarthritis and cardiovascular diseases. This challenges previous assumptions that osteoarthritis primarily increases the risk of cardiovascular issues.
These insights help explain earlier research indicating that patients with osteoarthritis have a 24-69% higher risk of developing cardiovascular disease compared to the general population.
Furthermore, understanding the unique environmental factors influencing these conditions could lead to better prevention strategies for both diseases.
