Hi, In general, life expectancy and prognosis after CABG, stent placement, and heart failure depend on many factors, including age, overall health status, severity of coronary artery disease, comorbidities, and response to treatment. Your healthcare provider would be the best person to discuss your prognosis and life expectancy with, as they can provide a personalized evaluation based on your medical history, test results, and other factors. It s also important to note that while some individuals with heart disease may experience reduced life expectancy, others may live a long and healthy life with proper management and care. With appropriate medical treatment, lifestyle modifications, and ongoing monitoring, it s possible to improve symptoms, slow disease progression, and manage heart failure and angina. I recommend discussing your concerns and questions with your healthcare provider, who can provide you with more specific information about your individual case and help develop a treatment plan to manage your condition. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Diwashish Biswas, Internal Medicine Specialist
