Effects of high altitude on arterial stiffness and neuro-cardio-pulmonary function were studied. Blood pressure (BP) and heart rate (HR) were measured in a sitting position on resting Ladakhis, living at an altitude of 3250-4647 m (Phey village, 3250 m: 17 men and 55 women; Chumathang village, 4193 m: 29 men and 47 women; Sumdo village, 4540 m: 38 men and 57 women; and Korzok village, 4647 m: 84 men and 70 women). The neuro-cardio-pulmonary function, including the Kohs block design test, the Up and Go, the Functional Reach and the Button tests, was examined in 40 elderly subjects (19 men and 21 women, mean age: 74.

- The study compared the effects of aging on blood pressure (BP) and heart rate (HR) in high-altitude Leh, Ladakh (3524 m) and low-altitude U town, Hokkaido (25 m).
- High-altitude residents showed higher diastolic BP (83.2 mmHg vs. 76.9 mmHg) and HR (78.6 bpm vs. 69.2 bpm) compared to lowland residents, with significant increases in BP with age, especially in the high-altitude group.
- The researchers concluded that a better understanding of cardiovascular health in high-altitude populations is crucial for prevention and treatment of related health issues like strokes.
