Intervention model: PARALLEL
Intervention model description: This study includes 15 patients diagnosed with Pulmonary Hypertension in Gazi Medical School Hospital Department of Pediatric Cardiology and 40 healthy children who applied to Gazi University Medical School Pediatric Cardiology Clinic
Primary purpose: DIAGNOSTIC

Brief summary: Our study aims to investigate the changes in muscle strength and muscle mass in PAH patients compared to healthy individuals and determine its effects on prognosis.

Further categorization of PAH patients based on their NYHA class will help determine if their handgrip strength decreases while progressing from NYHA class 1 to 4. This in turn allows us to examine if the handgrip test can be considered as an alternative to a 6-minute walking test (6MWT).

The Jamar Hydraulic Hand Dynamometer device in our hospital is used for measuring the handgrip strength test.

The data of the included subjects in this study are obtained and recorded from the existing files. Also, the handgrip strength test data will be recorded after the investigation

Detailed description: In our study, dynamometer tests will be applied to approximately 15 patients diagnosed with PAH. For control purposes, a hand dynamometer test will be applied to 40 healthy children. Patients' age, gender, weight, height, NYHA class, used medications, complete blood count (Hb, Hct, MCV, RDW), BNP, Troponin-t, biochemical parameters, catheterization findings at diagnosis, Echocardiographic findings (Tricuspid Annular Plane Systolic Excursion-TAPSE), Right Ventricular End Systolic Remodeling Index (RVES-RI), Pulmonary Artery acceleration Time (PAaccT), Tricuspid Velocity Time Integral (TR-VTI), RV area, RV length, Right Ventricular Load Adaptation Index (RV LAI), congenital heart disease and whether there is a shunt recorded or not. Patients are informed about the test before the dynamometer test. This may affect the integrity and accuracy of test results. To prevent such inaccuracies, the test will be performed on patients' both hands and the results are not recorded. Patients are asked to sit in a specific position. That is to sit upright with their elbows flexed 90° and the palms facing inwards (medially). Then, the test is performed 3 times with both hands. The results are recorded as the average of all the trials for dominant and non-dominant hands separately. The length of patients' hands is also measured. With the help of this test,it is possible to measure the difference in handgrip strength between healthy subjects and PAH patients. Additionally, patients are divided into 4 groups based on their NYHA classes. This will investigate if the patients' handgrip strength decreases as progress from NYHA class 1 to 4
