Chronic Thromboembolic Pulmonary Hypertension After Pulmonary Embolism

Study Purpose

to detect the incidence of CTEPH patients. Primary outcome To predict CETHP in symptomatic patients after pulmonary embolism episode. Secondary outcome: On Echocardiography revealed RV dysfunction which are peak TR Velocity , the RV/LV basal diameter ratio, flattening of the IVS, RV acceleration time and/or midsystolic notching, IVC diameter with decreased inspiratory collapse and RA area.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years - 80 Years
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06081881
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Chronic thrombo embolic pulmonary hypertension(CTEPH)is a progressive pulmonary vascular disease characterized by chronic obstruction of major pulmonary arteries with flow-limiting organized thrombi. In the clinical classification of the 6thWorld Symposium on Pulmonary Hypertension, CTEPH/chronic thromboembolic pulmonary disease(CTED)are in group4, labeled as PH due to pulmonary artery obstruction. CTEPH should be considered in PE patients if:(1)they report symptoms that could be related to CTEPH or with frank right heart failure,(2)the CTPA used to diagnose acute PE shows signs indicative of CTEPH,(3)they have risk factors or predisposing conditions for CTEPH. Recurrent venous thromboembolism(VTE),post-thrombotic syndrome, bleeding ,and functional limitations as important outcome measures of acute PE treatment , Dyspnea ,anxiety, chest pain ,post-thrombotic panic syndrome, and depression that lead to persistent functional limitations and/or decreased quality of life have been labeled as post-PE syndrome(PPS),includes CTEPH. Early diagnosis of CTEPH is important ,as it is the only form of PH that is potentially curable , but also challenging because signs of right heart failure only become evident in advanced disease stages and earlier disease stages are characterized by non specific or even absence of symptoms. The diagnostic work up of suspected CTEPH ,starts with trans thoracic Doppler echocardiography, In addition to the peak tricuspid regurgitation velocity , the right ventricle/left ventricle basal diameter ratio, flattening of the interventricular septum, right ventricular acceleration time and/or mid systolic notching, inferior vena cava diameter with decreased inspiratory collapse and right atrial area are used echocardiographic signs to assess the probability of PH.
