Area of Science:

  • Cardiology
  • Pulmonology
  • Medical Diagnostics

Background:

  • Pulmonary arterial hypertension (PAH) is a severe condition marked by increased pulmonary vascular resistance, leading to right ventricular failure and early mortality.
  • Accurate diagnosis is crucial for effective management and improved patient outcomes in PAH.

Purpose of the Study:

  • To outline the current diagnostic approach for Pulmonary arterial hypertension (PAH) based on recent clinical classifications and consensus guidelines.
  • To detail the array of investigative tests and procedures essential for excluding other conditions and confirming PAH.
  • To highlight the importance of monitoring disease severity using invasive and non-invasive markers.

Main Methods:

  • Review of established clinical classifications and consensus algorithms for PAH diagnosis.

Related Experiment Videos

  • Compilation of diagnostic procedures including clinical assessment, imaging (ECG, X-ray, CT, ultrasound), functional tests (PFTs, ABGs, exercise capacity), and hemodynamic evaluation.
  • Inclusion of blood tests, immunology, and specific scans like V/Q lung scans and pulmonary angiography.

    • Main Results:

    • A clearly defined diagnostic pathway for PAH has been established.
    • A comprehensive list of non-invasive and invasive tests is available to aid diagnosis and exclude differential diagnoses.
    • Proposed invasive and non-invasive markers facilitate reliable monitoring of disease severity.

    Conclusions:

    • The current diagnostic strategy for Pulmonary arterial hypertension (PAH) integrates clinical, imaging, functional, and hemodynamic assessments for accuracy.
    • Standardized diagnostic algorithms and the use of validated severity markers are key to managing PAH effectively.
    • Continued research into biomarkers and physiological parameters will further refine clinical course monitoring.
