Abstract
Introduction: Interstitial lung diseases, also known as diffuse parenchymal lung diseases, are a heterogenous group of diseases which is characterized by progressive scarring and fibrosis of interstitium of the lungs. Interstitial lung disease can markedly reduces patient’s exercise capacity and make patient dependent on oxygen, and can be associated with pulmonary artery hypertension ( class 3 WHO classification ) with limited exercise capacity.
Aims and objectives: We present a study done in our center where 85 patients of ILD are subjected to undergo 2-D echocardiography to assess the pulmonary hypertension and the co-relation between pulmonary hypertension with 6 minute walk distance and FVC.2-D echocardiography showing PASP > 20 are classified into mild ( PASP 20-40), moderate (41-55 PASP) and severe( PASP > 55 ) based on ERS journal 2019, January edition.
Methodology: Patients of ILD are advised to get 2-D echocardiography, spirometry and 6 minute walk test done, and compared the results in UIP and NSIP patterns.
Results:
PARAMETER | UIP | NSIP |
Type of ILD | 63% | 31 % |
Severe pulmonary hypertension | 11 % | 7 % |
Moderate pulmonary hypertension | 38 % | 22 % |
FVC < 50 in severe pulmonary hypertension | 50% | 50 % |
Unable to perform 6 minute walk test in severe PASP categories. | 70 % | 50 % |
Conclusion: 1) The prevalence of severe pulmonary hypertension by 2 d echocardiography ( PASP > 55 ) is more in UIP pattern.
2) Decline in FVC is maximum in patients with severe pulmonary hypertension.
3) Majority of the patients with severe pulmonary hypertension are unable to perform 6 minute walk test.
