NCT07801859
Assessment of Heart Rate Variability HRV During Descent DE From 2850m to Sea Level and During Re-ascent A From Sea Level to 2850m in Patients With Pulmonary Arterial Hypertension PAH
To study the effect of relocation from high altitude (Quito Ecuador: 2850m) to sea level and re-ascent from sea level to 2850m on heart rate variability and other hemodynamic parameters in patients with pulmonary arterial hypertension PAH, who live permanently \>2600m.

Analysis of the Presence and Cardiac Functional Effects of Anti-NaV1.5 Autoantibodies in Patients With Metastatic Tumors
The overall aim of this study is to identify and characterize anti-NaV1.5 autoantibodies in patients with metastatic breast and colorectal cancer. These tumors are characterized by the presence of a specific target structure (called nNaV1.5) against which antibodies are produced. These antibodies may cross-react with a similar structure (called NaV1.5) that is found in the heart. This could affect channel function and increase the risk of arrhythmias.
