Prognostic Value of the Right Ventricular Function by Portable Ultrasound in Patients With Pulmonary Hypertension.

Study Purpose

Pulmonary arterial hypertension (PAH) is a disease characterized by obliteration and remodeling of small-caliber pulmonary arteries, progressively generating an increase in pulmonary vascular resistance, right heart failure, and death. Current guidelines recommend a multidimensional approach which includes clinical, echocardiographic, exercise and hemodynamic variables to classify patients by risk and thus define a prognosis and guide therapeutic decisions. There is a wide range of studies, which have shown a good correlation between standard echocardiography and portable cardiac ultrasound. There is no doubt about the usefulness of portable cardiac ultrasound in the intensive care unit, emergency department and even during hospital rounds; however, its usefulness during the daily examination in a follow-up consultation of patients at high risk of cardiovascular deterioration, such as patients with PAH, has not yet been demonstrated. There is evidence that a TAPSE measurement <17mm using standard echocardiography by a physician experienced in echocardiography predicts survival in patients with Pulmonary hypertension. We would like to know if patients with low TAPSE will have a higher proportion of morbidity events compared to patients with normal TAPSE measured by portable ultrasound.

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.

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.

NCT05343091
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

Pulmonary arterial hypertension (PAH) is a disease characterized by obliteration and remodeling of small-caliber pulmonary arteries, progressively generating an increase in pulmonary vascular resistance, right heart failure, and death. Current guidelines recommend a multidimensional approach which includes clinical, echocardiographic, exercise and hemodynamic variables to classify patients by risk and thus define a prognosis and guide therapeutic decisions. Transthoracic Echocardiography (TTE) currently plays an important role in the diagnostic algorithm of PAH as it is minimally invasive and readily available. Moreover, many echocardiographic parameters are closely related to pulmonary hemodynamics. Some TTE parameters are associated with mortality and surviving in these patients, such as: shortening fraction, presence of pericardial effusion, eccentricity index, systolic displacement of the tricuspid annular plane (TAPSE), size of the right atrium and right ventricular free wall strain. Ultrasound (US) is the only method which enables realtime bedside imaging of the heart. Focused cardiac US provides worthy diagnostic information useful for the the clinical management of critical care patients. The use of cardiac ultrasound in the last decade has gradually increased among non cardiologists. Pocket ultrasounds are part of the third generation of ultrasounds described in the literature. These have the characteristic of being light devices weighing less than 1kg and that can be carried in the pocket of the medical uniform. This leads many researchers to believe that in the not too distant future its use will be part of the physical examination routine, as the stethoscope is now. There is a wide range of studies, which have shown a good correlation between standard echocardiography and portable cardiac ultrasound. There is no doubt about the usefulness of portable cardiac ultrasound in the intensive care unit, emergency department and even during hospital rounds; however, its usefulness during the daily examination in a follow-up consultation of patients at high risk of cardiovascular deterioration, such as patients with PAH, has not yet been demonstrated. STATEMENT OF THE PROBLEM Does the measurement of tricuspid annular plane systolic displacement (TAPSE) by portable cardiac ultrasound have prognostic utility in the follow-up of patients with Pulmonary Hypertension? JUSTIFICATION There is evidence that a TAPSE measurement <17mm using standard echocardiography by a physician experienced in echocardiography predicts survival in patients with Pulmonary hypertension. However, the high costs of an apparatus to perform the standard echocardiogram study and the prolonged appointments to perform the study delay the diagnosis of treatment of progression of cardiovascular disease. Therefore, it is important to document the usefulness of using an accessible medical tool during the cardiopulmonology consultation for the follow-up of patients with pulmonary hypertension. HYPOTHESIS Patients with low TAPSE will have a higher proportion of morbidity events compared to patients with normal TAPSE.
