Letter by Eller et al regarding article, "Lower mortality from coronary heart disease and stroke at higher altitudes in Switzerland".

BACKGROUND Studies assessing the effect of altitude on cardiovascular disease have provided conflicting results. Most studies were limited because of the heterogeneity of the population, their ecological design, or both. In addition, effects of place of birth were rarely considered. Here, we examine mortality from coronary heart disease and stroke in relation to the altitude of the place of res...

Lower Mortality From Coronary Heart Disease and Stroke at Higher Altitudes in Switzerland

Background—Studies assessing the effect of altitude on cardiovascular disease have provided conflicting results. Most studies were limited because of the heterogeneity of the population, their ecological design, or both. In addition, effects of place of birth were rarely considered.

We investigated, whether cardiovascular risk factors and echocardiographic parameters in patients with nAF are similar to patients with known AF (kA...
