Sex-Specific Associations of Risks and Cardiac Structure and Function With Microalbumin/Creatinine Ratio in Diastolic Heart Failure.

ABSTRACT: Background: Heart failure with preserved ejection fraction (HFpEF) affects women more frequently than men. However, data on sex-specific associations of adverse health outcomes and left ventricular structure and function and with microalbuminuria in patients with HFpEF are scarce. Methods: In 1,334 participants enrolled in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) Trial, we estimated the sex-specific multivariable-adjusted risk and LV traits with urine microalbumin/creatine ratio (ACR), using Cox or linear regression. Results: In total, 604 (45.3%) were women. In multivariable-adjusted analyses, a doubling of ACR in both men and women was associated with higher posterior (+0.014 cm, p = 0.012/+0.012 cm, p = 0.033) wall thickness and left ventricular mass index (+2.55 mg/m2, p = 0.004/+2.45 mg/m2, p = 0.009), whereas was also associated with higher septal (+0.018 cm, p = 0.002) and left atrial volume index (+1.44 mL/m2, p = 0.001) in men. ACR was a key predictor of all-cause (HR, 1.11; p = 0.006) and cardiovascular (HR, 1.17; p = 0.002) death in women, whereas in men ACR was associated with HF hospitalization (HR, 1.23; p < 0.001), any hospitalization (HR, 1.06; p = 0.006), and myocardial infarction (HR, 1.19; p = 0.017). The interactions of sex with ACR were significant for hospitalization for heart failure and any hospitalization (p ? 0.034). Conclusions: Outcomes and cardiac structure and function in patients with HFpEF appear to be influenced by ACR that vary according to sex. In men, ACR was significant associated with LV diastolic function, hospitalization, and myocardial infarction, whereas in women was associated with mortality.

Project description:Aldosterone infusion results in left ventricular hypertrophy (LVH) and hypertension and may involve profibrotic and proinflammatory mechanisms. In turn, hypertension is the major cause of diastolic heart failure (HF). Adiponectin, an adipose-derived plasma protein, exerts antiinflammatory and anti-hypertrophic effects and is implicated in the development of hypertension and systolic HF. We thus tested the hypothesis that hypoadiponectinemia in aldosterone-induced hypertension exacerbated cardiac remodeling and diastolic HF. Wild-type (WT) or adiponectin-deficient (APNKO) mice underwent saline or aldosterone infusion and uninephrectomy and were fed 1% salt water for 4 wk. Blood pressure was increased in aldosterone-infused WT (132 +/- 2 vs. 109 +/- 3 mm Hg; P < 0.01) and further augmented in APNKO mice (140 +/- 3 mm Hg; P < 0.05 vs. aldosterone-infused WT). LVH was increased in aldosterone-infused WT vs. WT mice (LV/body weight ratio, 4.8 +/- 0.2 vs. 4.1 +/- 0.2 mg/g) and further increased in aldosterone-infused APNKO mice (LV/body weight ratio, 6.0 +/- 0.4 mg/g). Left ventricular ejection fraction was not decreased in either aldosterone-infused WT or APNKO hearts. Pulmonary congestion however was worse in APNKO mice (P < 0.01). The ratio of early ventricular filling over late ventricular filling (E/A) and the ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity (E/e'), measures of diastolic function, were increased in aldosterone-infused WT hearts and further increased in APNKO hearts (P < 0.05 for both). Renal function and cardiac fibrosis were no different between both aldosterone-infused groups. Aldosterone increased matrix metalloproteinase-2 expression in WT hearts (P < 0.05 vs. WT and P < 0.01 vs. APNKO). Myocardial atrial natriuretic peptide, interferon-gamma, and TNF-alpha expression were increased in aldosterone-infused WT hearts. Expression of these proteins was further increased in aldosterone-infused APNKO hearts. Therefore, hypoadiponectinemia in hypertension-induced diastolic HF exacerbates LVH, diastolic dysfunction, and diastolic HF. Whether or not adiponectin replacement prevents the progression to diastolic HF will warrant further study.

Project description:BackgroundUrine albumin-creatinine ratio (ACR) and protein-creatinine ratio (PCR) are important markers of kidney damage and are used for prognosis in persons with chronic kidney disease (CKD). Despite how commonly these measurements are done in clinical practice, relatively few studies have directly compared the performance of these 2 measures with regard to associations with clinical outcomes, which may inform clinicians about which measure of urinary protein excretion is best. We studied the association of ACR and PCR with common complications of CKD.Study designCross-sectional study.Setting & participants3,481 participants with CKD in the Chronic Renal Insufficiency Cohort (CRIC) Study.PredictorsACR and PCR.OutcomesWe examined the association between ACR and PCR with measures of common CKD complications: serum hemoglobin, bicarbonate, parathyroid hormone, phosphorus, potassium, and albumin.MeasurementsRestricted cubic spline analyses adjusted for estimated glomerular filtration rate (eGFR; calculated by the MDRD [Modification of Diet in Renal Disease] Study equation) were performed to study the continuous association with our predictors with each outcome.ResultsMean eGFR was 43±13 (SD)mL/min/1.73 m2 and median values for PCR and ACR were 140 and 46 mg/g, respectively. In continuous analyses adjusted for eGFR, higher ACRs and PCRs were similar and both were associated with lower serum hemoglobin, bicarbonate, and albumin levels and higher parathyroid hormone, phosphorus, and potassium levels. Across all outcomes, the associations of ACR and PCR were similar, with only small absolute differences in the outcome measure. Similar associations were seen in patients with diabetes mellitus.LimitationsParticipants largely had moderate CKD with low values for ACR and PCR, so results may not be generalizable to all CKD populations.ConclusionsIn persons with CKD, ACR and PCR are relatively similar in their associations with common complications of CKD. Thus, routine measurement of PCR may provide similar information as ACR in managing immediate complications of CKD.
