Background and Aims: Chronic obstructive pulmonary disease (COPD) is highly prevalent in the Nepalese population. It is associated with significant extrapulmonary effects among which cardiovascular complications are most common. Echocardiography evaluation mainly focused on effects on the right heart function is a salient tool to evaluate the presence of degree of pulmonary hypertension and also identify those group of patients who need more early aggressive therapy for the underling lung disease . We aimed to prospectively study the patients with diagnosed COPD with echocardiogram for evaluating the right heart.Methods: An observational, cross sectional study was done on 50 patients with COPD who were admitted at Bir Hospital and underwent echocardiographic evaluation from Dec 2015 –Dec 2016. All echocardiogaphic parameters focused on right heart and its function were assessed .Results: Out of total 50 COPD patients studied, majority of them were female (32 patients. 64%). The mean age group of the studied patients was 60.9 ±11.4 years. Pulmonary hypertension defined as sPAP>30 mmHg was evident in all of the patients ; with 30 patients (60% ), 14 (28 %) and 6(12 %) patients having severe, moderate and mild pulmonary hypertension respectively. RV dysfunction was evident with reduced average TAPSE values (1.59± 0.38 cm) and elevated RIMP values (0.58±0.16).Conclusion: Majority of COPD patients had evidence of pulmonary hypertension. Echocardiogram can be a helpful tool to assess early changes on the right heart size and function in patients with COPD and also monitor these patients for rapid progression of the illness.Nepalese Heart Journal 2017; Vol 14(2), 9-12

Abstract Purpose Pulmonary hypertension (PH) is characterized by a progressive remodelling of the pulmonary vasculature resulting in right heart failure and eventually death. The serotonin transporter (SERT) may be involved in the pathogenesis of PH in patients with chronic-obstructive pulmonary disease (COPD). This study investigated for the first time the SERT in vivo availability in the lungs of patients with COPD and PH (COPD+PH). Methods SERT availability was assessed using SERT-selective [11C]DASB and positron emission tomography/computed tomography (PET/CT) with dynamic acquisition over 30 min in 4 groups of 5 participants each: COPD, COPD+PH, pulmonary arterial hypertension, and a healthy control (HC). Time activity curves were generated based on a volume of interest within the middle lobe. Tissue-to-blood concentration ratios after 25 to 30 min (TTBR25–30) served as receptor parameter for group comparison and were corrected for lung tissue attenuation. Participants underwent comprehensive pulmonary workup. Statistical analysis included group comparisons and correlation analysis. Results [11C]DASB uptake peak values did not differ among the cohorts after adjusting for lung tissue attenuation, suggesting equal radiotracer delivery. Both the COPD and COPD+PH cohort showed significantly lower TTBR25–30 values after correction for lung attenuation than HC. Attenuation corrected TTBR25–30 values were significantly higher in the COPD+PH cohort than those in the COPD cohort and higher in non-smokers than in smokers. They positively correlated with invasively measured severity of PH and inversely with airflow limitation and emphysema. Considering all COPD patients ± PH, they positively correlated with right heart strain (NT-proBNP). Conclusion By applying [11C]DASB and PET/CT, semiquantitative measures of SERT availability are demonstrated in the lung vasculature of patients with COPD and/or PH. COPD patients who developed PH show increased pulmonary [11C]DASB uptake compared to COPD patients without PH indicating an implication of pulmonary SERT in the development of PH in COPD patients.

Introduction: Chronic obstructive pulmonary disease (COPD) has considerable effects on cardiac functions, including those of the right ventricle, left ventricle, and pulmonary blood vessels. Most of the increased mortality associated with COPD is due to cardiac involvement. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate the cardiac changes. Aims: We aimed to prospectively study the patients with diagnosed COPD with echocardiogram for evaluating the right heart. Materials & Methods: Our study was an observational, cross sectional study was done on 50 patients with COPD who were admitted at Department of Cardiology, CMCH and underwent echocardiographic evaluation from November 2017 –October 2018. All echocardiogaphic parameters focused on right heart and its function were assessed. Results: Out of total 50 COPD patients studied, majority of them were male (46 patients ,92%). The mean age group of the studied patients was 58.4 ±7.7 years. Pulmonary hypertension defined as sPAP>30 mmHg was evident in all of the patients; with 30 patients (60%), 14 (28 %) and 6(12 %) patients having severe, moderate and mild pulmonary hypertension respectively. RV dysfunction was evident with reduced average TAPSE values (1.59± 0.38 cm) and elevated RIMP values (0.58±0.16). Conclusion: Majority of COPD patients had evidence of pulmonary hypertension. Echocardiogram can be a helpful tool to assess early changes on the right heart size and function in patients with COPD and also monitor these patients for rapid progression of the illness.

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. COPD is frequently associated with comorbidities, the most common complication being pulmonary hypertension and subsequent right heart failure. The prevalence of pulmonary hypertension and the pathophysiological processes of its installation in patients with COPD remain insufficiently studied, although it is known that its share increases with the severity of COPD, and its rate has been reported ranging from 20% to 90%. in the article, the author summarizes the notorious international discoveries and local contributions in this field, elucidating the opportunities, challenges and perspectives of studying the problem. Multiple investigations conducted in the last three decades by local researchers have deepened the knowledge of the pathophysiology, clinic, diagnosis, treatment and prophylaxis of pulmonary hemodynamic and cardiac function disorders in patients with COPD. Further investigations in this area are needed.
