Ever wondered why you needed to share your family’s health history at a doctor’s clinic? Specific questions regarding health issues of your immediate family or close blood relatives give your doctor an insight into various health risks you might have now or in future. Those are medical conditions inherited by parents or grandparents through genes. Genes are passed from parents to children in DNA of eggs or sperms. Even a single mutation (fault) in gene can influence body systems and may lead to disorders. If any of the parents have a faulty gene, there are 50:50 chances of the child inheriting it.
Hereditary heart diseases are also a result of mutation in one or more genes and tend to run in families. Genes control almost all aspects of cardiovascular system including strengthening blood vessels, pumping capacity or communication of cells in the heart. A single genetic variation is enough to alter cardiovascular processes increasing the risk of developing a heart disease, attack or a stroke. Some of the most common hereditary cardiac disorders include; Arrhythmias, congenital heart diseases and cardiomyopathy. A family history of heart attack or stroke is also an established high-risk factor for the family members. High blood cholesterol, medically known as familial hypercholesterolemia also tends to run in families.
Let’s look at some ways by which we can deal with hereditary heart diseases and increase a patient’s chances of survival:
Early Diagnosis And Treatment: When one person in the family is diagnosed with a heart disease, it is strongly advisable for other family members to go in for screening. An early diagnosis can help in better treatment and management of the disease and impacts positively on patients’ life. Medical screening of siblings is highly recommended in case a person suffers a sudden cardiac death especially at a young age.
Watch out for these symptoms at a young age: Abnormal heart rhythm, asthma that does not get better with inhaler, seizures that do not improve with medication, extreme fatigue or shortness of breath are warning signals and need immediate medical attention.
Genetic Testing: Family members may opt for genetic testing to check if they carried genes of an inherited disorder.
Genetic Counselling: Genetic counselling deals with problems like anxieties and fear of attacks, confusion over disease and emotional difficulties in accepting the situation.
We may not be able to change the family history but we can surely change our environment, lifestyle and habits. Eating healthy and following an active lifestyle does help in prevention and management of such diseases.
