Early diagnosis of subclinical left ventricular dysfunction in postmenopausal women with rheumatoid arthritis

Abstract

AbstractObjectiveHeart failure is the most frequent cause of death among patients affected by rheumatoid arthritis(RA), in which high prevalence is independent of traditional risk factors. An early diagnosis of subclinical heart failure may be made by assessing left ventricular diastolic dysfunction (LVDD) by Doppler Echocardiography. Our study aims to early identify LVDD in RA patients.MethodsWe enrolled 207 consecutive postmenopausal women (PMW) with normal electrocardiography and physical examination with a confirmed diagnosis of RA, for over one year, 200 PMW free from RA served as the control group (CG). All women underwent M‐mode and two‐dimensional Doppler echocardiography.ResultsA total of 72 women were affected by LVDD among 207 women with RA (34.8%), 46 among 200 women in the CG (23%), chi‐squared 6.8, OR 1.8, confidence interval (CI) 95%, p < 0.009. For our RA women, the chance of being affected by LVDD has almost doubled. There were 70 women affected by LVDD among 72 hypertensive women with RA (97.2%). A total of 32 women were affected by LVDD among 98 hypertensive women in the CG (32.7%), chi‐squared 72.1, OR 7.2, CI 95%, p < 0.009. Among hypertensive PMW in our population, the chance of being affected by LVDD has more than tripled. All LVDD subjects had abnormal diastolic function for all different degrees.ConclusionWe propose that PMW, affected by RA, have a significantly higher prevalence than CG of LVDD without clinical evidence of heart disease. Since the prevalence is even higher if they are hypertensive, we suggest a Doppler echocardiography examination for all women with a diagnosis of RA.
