Key result
Pulmonary hypertension in COPD is associated with marked RV systolic dysfunction on 2D echocardiography.
Why the study?
Echocardiography primarily focuses on the left ventricle while the right ventricle is often neglected due to technical imaging difficulties. Because the right ventricle is invariably affected in COPD, detecting RV dysfunction is needed to prevent future RV impairment.
Do 2D echocardiographic markers (FAC, TAPSE, RVs’, and RV MPI) predict right ventricular dysfunction in male COPD patients with mild-to-moderate pulmonary hypertension compared to those without pulmonary hypertension?

Answers are grounded in this paper and cite their sources.
2D echocardiographic parameters (FAC, TAPSE, RVs’, and RV MPI) are simple and useful predictors for assessing right ventricular function in COPD patients with mild-to-moderate pulmonary hypertension.
BACKGROUND Echocardiography assessment is primarily focused on left ventricle. Owing to the technical difficulty in imaging, right is neglected often. Since Right ventricle is invariably affected in COPD patients, it is imperative to find out the presence RV dysfunction in these patients to prevent RV impairment in future. AND METHODS study was done at Department of Cardiology, Govt. Vellore Medical College and Hospital, Adukkamparai, Vellore, Tamil during the period of October 2016 to March 2017 (Aloka Prosound Alpha 6 Echo machine was used). Seventy six male with COPD were taken up for the study. Group A (COPD alone): 36 patients without pulmonary hypertension were in this group. Group B (COPD with PHT): 36 patients with pulmonary hypertension (TR Velocity < 3.0 m/s; mean gradient < 45 mmHg) were included in this group. The following Echocardiographic measurements were made to all seventy two patients. (1). FAC (Fractional Area Change), (2). TAPSE (Tricuspid annular plane systolic excursion), (3). RVs’ (RV systolic excursion by Tissue Doppler) and (4). RV MPI (RV Myocardial Performance Index). patients with pulmonary hypertension showed marked deviation from reference values, while COPD patients without hypertension showed values above the physiological limits. this present study, we have found that 2D echocardiography markers like FAC, TAPSE, RVs’ and RV MPI were simple and good predictors of RV function. It was useful in assessing the RV function in COPD patients with mild-to-moderate hypertension.

Kannappan et al. (2017) conducted a cross-sectional in Chronic obstructive pulmonary disease (COPD) (n=72). 2D Echocardiography markers (FAC, TAPSE, RVs’, RV MPI) in COPD with pulmonary hypertension vs. COPD without pulmonary hypertension was evaluated on Right ventricular (RV) function assessed by FAC, TAPSE, RVs’, and RV MPI.
