Examining blood flow changes in hypertension

Non-Invasive HaemoDYNAMICs in Primary and Secondary Hypertension: the DYNAMIC-study

Observational Tampere University · NCT01742702

This study is testing how blood flow changes in people with high blood pressure compared to those with chronic fatigue syndrome to better understand their heart health.

What this trial studies

This study investigates the haemodynamic changes in individuals with primary and secondary hypertension using non-invasive measurement techniques. It employs radial pulse wave analysis and whole-body impedance cardiography to assess various cardiovascular parameters in both supine and upright positions. The study also includes a control group of subjects with chronic fatigue syndrome for comparison. The aim is to better understand the functional haemodynamic status of hypertensive patients and how it differs among various conditions.

Who should consider this trial

Good fit: Ideal candidates include independent adults with primary or secondary hypertension, as well as normotensive control subjects and those with aortic stenosis.

Not a fit: Patients who are pregnant or have low blood pressure (systolic blood pressure <90 mmHg) may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of hypertension, potentially reducing cardiovascular complications.

How similar studies have performed: Other studies have shown success with similar non-invasive haemodynamic measurement approaches, indicating potential for valuable insights.
