Life expectancy in Class II heart failure is based on how well the heart failure is controlled and varies widely among individuals and cannot be generalized.
Heart function is graded, according to the New York grading scale, into four levels. In Class I heart failure, activity is largely unrestricted, with symptoms of chest tightness and shortness of breath only during severe physical labor. Grade II heart failure is slightly limited in activity, but when resting, there are no uncomfortable symptoms.
Grade III, is the normal physical activity, obviously limited, a little activity will have chest tightness, shortness of breath symptoms. Grade IV, is the patient resting state, also will appear heart failure symptoms.
If the heart failure is grade II a clear cause has been identified and removed. In the acute phase of heart failure, i.e., symptoms such as chest tightness, drugs such as digoxin, furosemide and nitroglycerin are taken.
In the remission phase of heart failure, after taking propranolol, captopril, spironolactone and other drugs to improve myocardial remodeling, the condition is relieved, and the life expectancy at this time is actually the same as that of a normal person. The above drugs need to be under the guidance of a professional physician.
However, if the treatment of secondary heart failure is not standardized, or when it is not treated in any way, it can produce many adverse events and affect life expectancy.
