Abstract:
The invasive cardiopulmonary exercise test (iCPET) provides a comprehensive, simultaneous evaluation of an individual's cardiovascular, respiratory, and metabolic response to exercise. The test is uniquely suited for the evaluation of exercise intolerance, as well as the deep phenotyping of disease states including pulmonary arterial hypertension and post-coronavirus disease symptomatology. Despite an expanding list of clinical and research applications, both the complexity of the test and a lack of familiarity with how the test is performed have been barriers to the widespread use of iCPET. The aim of this article is to provide practical insights into how an iCPET is performed.

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
