Genetic and inherited heart diseases are a group of conditions that result from abnormalities in the genetic code, affecting the structure and function of the heart. These diseases, such as familial hypercholesterolemia, hypertrophic cardiomyopathy, and arrhythmogenic right ventricular dysplasia, are passed down through families and often present early in life. Early detection through genetic screening and family history assessment can help identify individuals at risk and enable timely interventions. Personalized treatments, including medication, lifestyle changes, and in some cases, genetic therapies, are essential for managing these conditions. Understanding the genetic basis of heart disease is key to preventing the onset of symptoms, improving outcomes, and reducing the risk of sudden cardiac events.
