Various types of heart disease include rheumatic, hypertensive, ischemic, cerebrovascular, and inflammatory diseases, each requiring awareness and preventive actions. Key risk factors include tobacco use, obesity, high blood pressure, and lack of physical activity, along with symptoms such as chest pain and shortness of breath; lifestyle changes and regular medical check-ups can significantly aid in prevention.
