The prognosis of people with heart failure can vary dramatically. The following factors may help the doctor estimate the prognosis.
The severity of the symptoms: It is well established that patients who have more severe symptoms of heart failure do not survive as long as those who have mild symptoms. For example, patients with class IV heart failure have the poorest prognosis, while patients with class I have the best.
Heart function: The ejection fraction of left ventricle (LVEF) is an important indicator of the prognosis. The more severely damaged your heart muscle is, the worse your ejection fraction and worse prognosis will be, regardless of your symptoms.
The causes of heart failure: Heart failure associated with alcohol use or pregnancy may spontaneously recover itself over time. Heart failure can be caused by treatable conditions such as hyperthyroidism or hypothyroidism, anemia, or vitamin deficiency. The prognosis of these conditions are generally excellent. Heart failure as a result of a valve condition may also be reversible if the valve problem is recognized early and fixed before permanent damage happens. People with heart failure caused by severe hypertension may see considerable improvement of their symptoms when they control their hypertension. But the majority of patients have heart failure as a result of coronary artery disease (CAD) have a worse prognosis and a higher death rate than people who have heart failure that is not a result of CAD.
How long you've had heart failure: There is no specific length of time after which your heart function is unlikely to improve. General speaking, the longer you have had heart failure, the poorer prognosis may be even with appropriate treatment.
Compensatory factors: "compensatory factors" are various adjustments to correct the effects of heart failure on other organs. When heart failure occurs, various hormone levels including renin, aldosterone, norepinephrine, atrial natriuretic peptide, and prostaglandin, may increase. Increases in these hormonal factors and other compensatory factors often make heart failure worse over time.
