My 33 yr old son had a heart attack 10-15. He now has dx of chronic combined systolic and diastolic congestive heart failure. Ef of 40. How serious?

Heart failure. Heart failure caused by a prior myocardial infarction (heart attack) is a very serious problem. Fortunately there are well-defined treatments including medications and procedures. Patients with this condition should be under the care of a cardiologist. It may also help to get a second opinion here on HealthTap to review treatment options.
