Remote monitoring and automatic analysis of phonocardiographic signals in climbing of high mountains [PDF]

open access: yes, 2006
The climbing of high mountains, like the Himalayas, comes accompanied, as result of the deficit of oxygen, of certain changes of the hemodynamics, that can derive sometimes in High Altitude Pulmonary Edema (HAPE).

Hypertension‐specific association of cardio‐ankle vascular index with subclinical left ventricular function in a Chinese population: Danyang study

open access: yesThe Journal of Clinical Hypertension, Volume 26, Issue 5, Page 553-562, May 2024.
Abstract The association of cardio‐ankle vascular index (CAVI), with subclinical cardiac dysfunction in hypertensive patients is unclear. We aim to examine their relationship in hypertensive patients compared with that in normotensive subjects. Our study included 1887 subjects enrolled from Danyang between 2018 and 2019.
