Pulmonary hypertension (PH) is a disease with a very poor prognosis. Although primary PH remains a rare pathology, PH related to other diseases is being diagnosed quite often. Chronic respiratory disorders, hypoxia, thromboembolic events, valvular disorders, systolic and diastolic dysfunction etc have all been listed as potential pathologies that can lead to the development of the secondary PH. One of the reasons for the increased prevalence of the secondary PH is attributed to the aging population. The aim of our study is to identify the etiological factors (comorbidities) that contribute to the development of the secondary PH in geriartric population.
We conducted a retrospective analysis of 153 elderly patient charts after an echocardiografic study, which identified moderate pulmonary hypertension (>50mm Hg). The medical charts were reviewed in detail, data from the echo-lab and findings from the computerized tomography (CT) of the chest were analyzed.
The study population consisted of elderly patients (mean age 76.8) 66% male and 44 females. Systemic hypertension was found to be present on 72 % of the patients (110). Two (1.3%) patients were found to have severe mitral valve dysfunction. Left atrium and left ventricule diameter was enlarged in 75% (115) of the patients. Moderate to severe systolic dysfunction (EF<30%) was recorded in 28% (43) of the patients and dyastolic dysfunction in 17% (26). CT findings were categorized in normal findings, airway disease, interstitial/ inflammatory changes, and pulmonary embolisms (PE), respectively 12%, 20%, 68%, 11%. In a few CT’s combined interstitial changes with pulmonary embolism were found.
The etiology of secondary pulmonary in geriartric population is mainly attributed to systemic hypertension, interstitial/inflammatory pulmonary disorders, systolic and diastolic dysfunction. History of airway disease, PE, and valvular dysfunction are also important.
Aggressive treatment of cardiopulmonary disorders in geriartric population can delay or even stop the development of the secondary PH.
