Cyclic guanosine monophosphate and 10-year change in left ventricular mass: the Multi-Ethnic Study of Atherosclerosis (MESA).

ABSTRACT: Purpose: Cyclic guanosine monophosphate (cGMP) is a second messenger for natriuretic peptide (NP) and nitric oxide pathways; its enhancement a target for heart failure and cardiovascular disease (CVD). We evaluated whether plasma cGMP was associated with change in left ventricular mass (LVM) among individuals free of CVD and if this differed by sex.Methods and Results: In 611 men and 612 women aged 45-84 years with plasma cGMP measured at baseline and cardiac MRI performed at baseline and 10 years later, we tested associations of cGMP [log-transformed, per 1 SD increment] with LVM, adjusting for CVD risk factors and N-terminal pro-B-type-NP (NT-proBNP). Participants had mean (SD) age of 63.1(8.5) years and cGMP 4.8(2.6) pmol/mL. Cross-sectionally, higher cGMP was associated with lesser LVM, non-lin- early. In contrast, longitudinally, higher cGMP was associated with increase in LVM [1.70g (0.61, 2.78)] over 10 years. Higher cGMP was associated with greater LVM change in men [2.68g (1.57, 3.79)] but not women [0.24g ((-0.92, 1.39); p-interaction < 0.001].Conclusion: In conclusion, in a community-based cohort, higher cGMP levels were associated with increase in LVM over 10 years independent of CVD risk factors and NT-proBNP in men, perhaps reflecting compensatory changes. Further studies are needed to understand mechanistic roles of cGMP in LV remodelling and associated sex differences.

Project description:Background Left atrial (LA) and left ventricular (LV) structural and functional parameters have independent prognostic values as predictors of atrial fibrillation (AF). Purpose To investigate the prognostic value of a left atrioventricular coupling index (LACI) and average annualized change in LACI (hereafter, ΔLACI) measured by cardiac MRI to predict incident AF in a population-based sample from the Multi-Ethnic Study of Atherosclerosis (MESA). Materials and Methods In a secondary analysis of the prospective MESA, 1911 study participants without clinically recognized AF and cardiovascular disease at baseline had LACI assessed with cardiac MRI at baseline (examination 1, 2000-2002) and 10 years later (examination 5, 2010-2012). LACI was defined as the ratio of LA to LV end-diastolic volumes. Univariable and multivariable Cox proportional hazard models were used to evaluate the associations of LACI and average ΔLACI with incident AF. Results Among the 1911 participants (mean age, 59 years ± 9 [standard deviation]; 907 men), 87 incident AF events occurred over 3.9 years ± 0.9 after the second imaging (examination 5). After adjustment for traditional risk factors, greater LACI and ΔLACI were independently associated with AF (hazard ratio, 1.69 [95% CI: 1.46, 1.96] and 1.71 [95% CI: 1.50, 1.94], respectively; both P < .001). Adjusted models for LACI and ΔLACI showed improvement in model discrimination compared with currently used AF risk score (Cohort for Heart and Aging Research in Genomic Epidemiology-Atrial Fibrillation, or CHARGE-AF, score) model (area under receiver operating characteristic curve [AUC], 0.78 vs 0.74; and AUC, 0.80 vs 0.74, respectively; both P < .001); and to the final model including individual LA or LV parameters for predicting AF incidence (AUC, 0.78 vs 0.76; and AUC, 0.80 vs 0.78, respectively; both P < .001). Conclusion Atrioventricular coupling (left atrioventricular coupling index [LACI]) and coupling change (annual change in LACI) were strong predictors for atrial fibrillation (AF) in a multiethnic population. Both had incremental prognostic value for predicting AF over traditional risk factors, and superior discrimination compared with the Cohort for Heart and Aging Research in Genomic Epidemiology-Atrial Fibrillation, or CHARGE-AF, score and to individual left atrial or left ventricular parameters. © RSNA, 2022 Online supplemental material is available for this article.
