About this study

Official title: HbA1c as an Early Serologic Marker for the Hemodynamic Progression of Stage A Heart

In a retrospective community based cohort study from Pueblo County Colorado which has a higher population proportion of metabolic syndrome and diabetes mellitus, we hope to clarify and quantify an association of the AGE HBa1c elevation with the early subclinical hemodynamic changes of diabetic cardiomyopathy as measured by LAV, LVM, E/A ratio, E/e' ratio and BNP in patients with stage A heart failure.

Read the detailed description

The classic association of glycemic control, as represented by HBa1c, with progression or improvement of microvascular and macrovascular clinical complications has been well documented. Additionally, while the association of HBa1c elevation with a syndrome described as diabetic cardiomyopathy has also been well documented, the use of the advanced glycation end product axis (AGE/sRAGE/esRAGE which includes HBa1c) as markers for the early subclinical hemodynamic changes of diabetic cardiomyopathy has been suggested but less well characterized or utilized. Stage A heart failure is defined as persons with normal cardiac structure and function who have predisposing subclinical risks for cardiovascular disease. Estimates suggest that Stage A heart failure may comprise up to 56% of any community's patient population and are patients most commonly seen in non-specialty primary care clinics. In light of newer cardiometabolic agents which show promise in cardiovascular disease primary prevention, these patients may be an important target for preventative cardiometabolic care. In a retrospective community based cohort study from Pueblo County Colorado which has a higher population proportion of metabolic syndrome and diabetes mellitus, we hope to clarify and quantify an association of the AGE HBa1c elevation with the early subclinical hemodynamic changes of diabetic cardiomyopathy as measured by LAV, LVM, E/A ratio, E/e' ratio and BNP in patients with stage A heart failure.

Methods: Retrospective cohort analysis by chart review of patients presenting to Parkview Medical Center's inpatient service and outpatient clinics who obtained a full resting echo characterized by normal cardiac structure and function in conjunction with HBa1c and BNP levels within a 3 month time window. Using multiple regression analysis of the dependent variables LAV, LVM, E/A ratio, E/e' ratio and BNP, powered to detect a 5% change in LAV in conjunction with rising HBa1c levels characterized as normal (<5.7), metabolic syndrome (5.7-6.4) or diabetic (>6.4) after controlling for the presence of hypertension and coronary artery disease.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Glycosylated hemoglobinDiagnostic test

    Also called Echocardiogram

    Glycosylated hemoglobin levels associated with correlative measures of diastolic cardiac function

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Left Atrial volume

    Echocardiogram

    Measured: 3 months

Secondary outcomes (2)

  1. BNP

    Serum total values in pg/ml

    Measured: 3 months

  2. E/e'

    Echocardiogram measure of the ratio of early LA to LV diastolic inflow velocity (E) to tissue doppler measure of mitral annular early diastolic velocity (e') in m/sec. This is a marker of left atrial pressure.

    Measured: 3 months
