The initial signs and symptoms of heart failure in people with rheumatoid arthritis are less obvious than in other patients, yet the death rate is higher, new research shows.
"It is conceivable that the subtle presentation of heart failure among patients with rheumatoid arthritis leads to difficulty in diagnosis and influences management," the researchers comment in their report in the medical journal Arthritis and Rheumatism.
Dr. John M. Davis, from the Mayo Clinic in Rochester, Minnesota, and colleagues based their findings on a study of people diagnosed with heart failure who were living in Olmsted County, Minnesota; 103 of them had rheumatoid arthritis and 852 did not.
As noted, the usual signs and symptoms of heart failure were less common in the rheumatoid arthritis group. In addition, arthritis patients were less likely to be checked out in detail by ultrasound examination of their hearts.
In fact, the hearts of people with rheumatoid arthritis were more likely than those of the others to have fairly well preserved pumping capacity. Nonetheless, the 1-year mortality rate after heart failure in arthritis patients was 35 percent, significantly higher than the 19 percent seen in non-arthritis patients.
The findings suggest that doctors need to be extra vigilant in looking for the signs of heart failure in people with rheumatoid arthritis, the authors conclude.

These are the reasons why everyone diagnosed with RA or PsA should have a cardiac consultation. If I hadn't read some research about RA and cardiac events, talked with my primary care doctor and gave him the research then I might have had a different outcome regarding my own cardiac issues. I was referred to a cardiologist for a routine exam, ekg, and whatever else the cardiologist deemed necessary. My ekg showed a problem and the rest is history. I'm fine now but the outcome could have been entirely different if I hadn't my own advocate and insisted on a referral to a cardiologist. Many of the diseases of the heart are silent. Lindy
