Heart disease is a group of diseases that affect the heart. The World Health Organization notes that cardiovascular diseases are the leading cause of death worldwide. Every year many people die from this disease than from another.
The causes for which a person can develop heart disease are multiple. Genetic factors come into play since a person with a family history who has had some type of cardiovascular disease can lead to this being developed. Some factors relate to the state of health that a person carries. People who have a poor diet, do little physical activity and abuse substances such as alcohol and cigarettes, are more likely to develop heart disease.
Among the most common diseases are:
- Arterial hypertension
- Coronary cardiopathy
- Cerebrovascular disease
- Heart failure
- Cardiomyopathies
- Congenital heart disease
As Jamal has realized that inheriting heart disease is possible, he must take certain actions to minimize the chances and have better health. Some of the actions that Jamal must do are:
- Make periodic visits to the doctor to know the current state of health and avoid the development of any heart disease or another in general.
- Implement a healthy diet where it includes more fruits and vegetables and set aside foods with saturated fats.
- Reduce the intake of alcohol and any type of drug without a prescription
- Avoid situations where it can develop high levels of stress and anxiety.
- Keep track of the arterial pressure.
- Exercise moderately.
- Sleep enough hours. A person who does not sleep the number of hours needed can develop symptoms such as irritability and stress, which can influence the development of heart disease.
