Purpose:
to assess pulmonary hypertension (PH) in patients with chronic obstructive pulmonary disease (COPD) plus diabetes mellitus (DM) using transcutaneous Doppler right jugular venous echo (tDErjv).
Material And Methods:
We examined 5 groups of patients and control group (30 healthy subjects). The 1st group consisted of 55 COPD in-patients in exacerbation with type II DM (DM2). The 2nd group' was formed of 40 in-patients with sole COPD in exacerbation. 30 patients with sole DM2 were included in the 3rd group. The 4th group consisted of 15 COPD in-patients with type I DM (DM1). The 5th group was formed of 18 patients with DM1. The following parameters, using tDErjv, were determined: direction of flow (antegrade or retrograde), velocities of systolic (Sf) and diastolic flows (Df), which are in the strong correlation with the mean pulmonary artery pressure (mPAP). If the flow was biphasic, the ratio of velocities (Df/Sf) and mPAP were calculated.
Results:
Antegrade biphasic flow was revealed in all patients. Sf>Df and Df/Sf
Conclusions:
PH was more severe in COPD plus DM2 as compared with COPD only. tDErjv allowed determining mPAP in all COPD patients, even with the severe emphysema.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
