Conditions

Menopause, Sleep Disruption, T2DM

Brief summary

EMPOWER aims to determine the overall effect of menopause and sleep disruption on cardiac remodeling in women with type 2 diabetes.

Detailed description

The EMPOWER prospective cohort study is part of a larger project. This interdisciplinary project will utilize animal models, clinical cohorts, epidemiological datasets and data from randomized control trials to explore the hypothesis that sleep disruption and menopause-induced hormonal changes synergistically increase systemic inflammation and impair incretin signaling, leading to worsened cardiac function, heightened cardiometabolic dysfunction, and accelerated CVD risk. The EMPOWER study aims to determine the cumulative effect of multiple exposures including menopause progression and sleep disruption on subclinical cardiac remodeling in women with T2DM in the perimenopausal transition and if these relationships are moderated by T2DM management, Body Mass Index (BMI), or inflammation.

Interventions

OTHER4 years of clinical evaluations.

The intervention in this study is the additional clinical evaluations for women with type 2 DM and in perimenopause.

Design outcomes

Primary

MeasureTime frameDescription
Reduced septal e' velocityBaseline to 4 years.Indicates impaired relaxation of the left ventricle during early diastole; key marker for diastolic dysfunction. Measured by echocardiography.
Increased E/e' ratioBaseline to 4 years.Indicates elevated left ventricular filling pressure; key marker for diastolic dysfunction. Measured by echocardiography.
Increased tricuspid regurgitation (TR) velocityBaseline to 4 years.Indicates elevated right ventricular systolic pressure or pulmonary hypertension. Measured by echocardiography.
Change in pulmonary artery systolic pressure (PASP)Baseline to 4 years.Measures the pressure in the pulmonary artery when the heart beats. Measured by echocardiography.
Change in E/A ratioBaseline to 4 years.Decrease of E/A ratio below 1 indicates diastolic dysfunction, and an increase of E/A ratio over 2 indicates advance failure. Measured by echocardiography.
Change in left atrial sizeBaseline to 4 years.Left Atrial Enlargement (LAE) is abnormal stretching or widening of the upper left heart chamber, typically caused by chronic pressure or volume overload. Measured by echocardiography.

Secondary

MeasureTime frameDescription
Decline in left ventricular global longitudinal strain (GLS)Baseline to 4 years.Detects heart muscle dysfunction. Measured by echocardiography.
Decline in left atrial strainBaseline to 4 years.Indicates left ventricular diastolic dysfunction, heart failure with preserved ejection fraction, and atrial fibrillation. Measured by echocardiography.
