Effect of Progression of Valvular Calcification on Left Ventricular Structure and Frequency of Incident Heart Failure (from the Multiethnic Study of Atherosclerosis)
Section snippets
Methods
The Multiethnic Study of Atherosclerosis (MESA) is an ethnically diverse cohort of 6,814 women and men aged 45-84 years old enrolled between July 2000 and August 2002 from Forsyth County, NC; Northern Manhattan and the Bronx, NY; Baltimore City and Baltimore County, MD; St. Paul, MN; Chicago, IL; and Los Angeles County, CA.12 The study design and methods are available at http://www.mesa-nhlbi.org and have been previously described.12 Participants were free of clinical cardiovascular disease and
Results
We studied 5591 MESA participants with mean (SD) age of 61.8 (10.2) years, 53% were women, and 40% White. At the time of baseline CT scan, 691 (12%) had prevalent AVC and 502 (9%) prevalent MAC. Eighty-three percent of participants had no progression of VC, 15% had progression of VC at only 1 site (AVC or MAC), and 3% at both sites (AVC and MAC) after a median of 2.4 years of follow-up. Table 1 shows the baseline characteristics of study participants stratified by number of sites with
Discussion
Baseline CAC and CAC progression have previously been shown to be associated with incident HF.11,20 In this study, we now show that progression of VC at 1 or both sites after a median of 2.4 years is associated with an increased risk of HF in this multiethnic community-based cohort free from clinical cardiovascular disease at baseline independent of ASCVD risk factors. We also found stronger associations with the incidence of HFpEF, with a greater than twofold risk of HFpEF with VC progression,
