Observational Study of Sublingual Microcirculation in Patients With Chronic Cardiovascular Disease.

ABSTRACT:

Background

Sublingual video microscopy is increasingly used to study the microcirculation in acute illness. However, the sublingual microcirculation in patients with chronic cardiovascular diseases (CVD) is understudied. Our objective was to quantify sublingual microcirculatory parameters in a large cohort of patients with CVD.

Methods

One hundred and thirteen patients with CVD were enrolled. Incident dark-field handheld video microscopy (IDF-HVM) was used to quantify microvascular flow index (MFI), microvascular heterogeneity index (MHI), proportion of perfused vessels (PPV), perfused vessel density (PVD), and total vessel density (TVD). Data were stratified by age quartiles (20-39, 40-59, 60-79, 80+), cardiovascular comorbidities (hypertension, diabetes, chronic kidney dis
