We say that some early-stage heart failure can be cured, such as peripartum cardiomyopathy and thyrotoxic cardiomyopathy. If discovered and treated early, there is hope for a cure. However, most heart failure cannot be cured. Although some psychological failures cannot be cured, if patients can receive early treatment and effective treatment, take their medication on time, and have regular check-ups as advised by their doctor, most heart failure can still be controlled or alleviated. However, if heart failure is detected and not actively treated, even mild heart failure may gradually worsen, or even become end-stage heart failure.
