This is not a diagnostic test. However, your scores can give information about your genetic risk of developing a particular condition compared to the average person. It does not determine who will develop the disease and who will not. You may already have one of the conditions assessed. You may or may not develop the conditions assessed regardless of your scores.
This polygenic score only provides an estimate of your genetic risk. There are many other factors that could affect your overall risk of developing cardiovascular disease, such as your diet, physical activity, and whether or not you smoke. These factors are not included in this score. Even if your polygenic score suggests a high genetic risk, there are steps you can take to lower your overall risk for cardiovascular disease.
The American Heart Association provides recommendations for improving and maintaining cardiovascular health on their website. You and your doctor can consider these together.
