Abstract Objective Chronic high-altitude exposure has been shown to reduce ischemia-reperfusion injury in animal experiments. The objective was to evaluate the clinical protective effect of long-term high-altitude hypoxic exposure for patients undergoing cardiac surgery with cardiopulmonary bypass. Methods In this retrospective cohort study, data from patients who underwent cardiac procedures between January 2013 and December 2019 at a single center was collected. Patients were divided into highlander group (> 2500 m) and lowlander group (< 1500 m) according to the altitude of their residence. A propensity-score-matched analysis was performed to estimate the association of long-term high-altitude exposure and cardiac surgery outcomes. Results In a total of 2085 patients, 128 highlander patients were matched to 248 lowlander patients. The levels of CK-MB and hs-TnI upon arrival at the intensive care unit were lower in the highlander group compared to the lowlander group [70.6 U/L (56.0, 92.6) vs 85.0 U/L (68.5, 113.5), P < 0.001; 6.1 ng/mL (3.3,11.2) vs 7.9 ng/mL (3.6, 14.1), P = 0.011, respectively]. The highlander group also had a lower incidence of acute kidney injury (13.3% vs 21.8%, P = 0.046). The in-hospital mortality in the highlander group was lower than in the lowlander group without statistical significance (0.8% vs 4.0%, P = 0.107). Conclusions Long-term high-altitude exposure was associated with less myocardial injury and a lower incidence of acute kidney injury after cardiac surgery.

Simultaneous Measurements

ABSTRACT We present optical turbulence profiles obtained with a Generalized SCIDAR (G-SCIDAR) and a low-layer SCIDAR (LOLAS) at the Observatorio Astronómico Nacional in San Pedro Mártir (OAN-SPM), Baja California, Mexico, during three observing campaigns in 2013, 2014, and 2015. The G-SCIDAR delivers profiles with moderate altitude-resolution (a few hundred metres) along the entire turbulent section of the atmosphere, while the LOLAS gives high altitude resolution (on the order of tens of metres) but only within the first few hundred metres. Simultaneous measurements were obtained on 2014 and allowed us to characterize in detail the combined effect of the local orography and wind direction on the turbulence distribution close to the ground. At the beginning of several nights, the LOLAS profiles show that turbulence peaks between 25 and 50 m above the ground, not at ground level as was expected. The G-SCIDAR profiles exhibit a peak within the first kilometre. In 55 per cent and 36 per cent of the nights stable layers are detected between 10 and 15 km and at 3 km, respectively. This distribution is consistent with the results obtained with a G-SCIDAR in 1997 and 2000 observing campaigns. Statistics computed with the 7891 profiles that have been measured at the OAN-SPM with a G-SCIDAR in 1997, 2000, 2014, and 2015 campaigns are presented. The seeing values calculated with each of those profiles have a median of 0.79, first and third quartiles of 0.51 and 1.08 arcsec, which are in close agreement with other long term seeing monitoring performed at the OAN-SPM.
