Article Synopsis
- High-altitude polycythemia (HAPC) poses risks to cardiovascular health in people living above 2500 m, particularly impacting hypertensive individuals but its effects on hypertension-mediated organ damage are not fully understood.
- In a study involving 88 hypertensive patients, half had HAPC and half did not; those with HAPC had higher hemoglobin levels, larger left atrium diameters, and a higher rate of impaired flow-mediated dilation.
- HAPC was found to significantly correlate with the increased left atrial size and impaired vascular function, with hemoglobin levels identified as an independent risk factor for these changes in the hypertensive group.
Objective: This study aimed to assess biventricular function and mechanics in patients with the chronic high-altitude disease (CHAD) using cardiovascular MRI and explore the possible risk factors associated with ventricular remodeling.
Methods: In this prospective study, consecutive CHAD patients and healthy controls at high-altitude (HA) and at sea level (SL) underwent cardiovascular MRI. Right ventricular (RV) and left ventricular (LV) function and global strain parameters were compared.
