The answer to this question is not a simple yes or no. While it is true that having a family history of heart disease increases your risk of developing it, it is not certain that inheritance from the mother is the sole cause.
Heart disease is caused by a combination of factors, including lifestyle, environment, genetics, and family history. While it is possible that genetic factors from the mother could contribute to the development of heart disease, other factors may also play a role.
For instance, lifestyle factors such as smoking, poor diet, lack of physical activity, and obesity can all increase the risk of developing heart disease. Environmental factors, such as exposure to air pollution or toxic chemicals, can also increase risk. In addition, family history is an important risk factor for heart disease—the more close relatives you have had with heart disease, the greater your risk.
Unfortunately, it is not possible to know for sure if any particular case of heart disease is due to genetics from the mother. The best way to reduce your risk of heart disease is to maintain a healthy lifestyle and to get regular check-ups with a doctor. If you have a family history of heart disease, it is important to discuss your risk with your doctor so that you can take steps to reduce your risk.
