The prognosis for RA is uncertain, because of the prolonged course of disease, the fact that the disease is so variable, and that many patients never even see a doctor for treatment, and therefore, are never counted in the statistical pool. When death does come prematurely it is usually from infection, pulmonary and renal disease, and GI bleeding. In my personal experience, this is not a common occurrence with today's current treatment.
