Trends and geographical variation in mortality from coronary disease in Peru
(Public Library of Science, 2022)
Background Coronary disease (CD) is the main cause of mortality worldwide. Data about trends and geographical variation in CD mortality is available in some American countries. This information varies among countries since ...
Sensitivity, specificity and predictive values of linear and nonlinear indices of heart rate variability in stable angina patients
(2012-10-31)
Background: Decreased heart rate variability (HRV) is related to higher morbidity and mortality. In this study we evaluated the linear and nonlinear indices of the HRV in stable angina patients submitted to coronary ...

Poincaré plot indexes of heart rate variability: Relationships with other nonlinear variables
(2013-10-01)
The Poincaré plot for heart rate variability analysis is a technique considered geometrical and non-linear, that can be used to assess the dynamics of heart rate variability by a representation of the values of each pair ...

Cardiovascular and renal effects of chronic exposure to high altitude
(Oxford University Press, 2012)
Over 140 million people live at high altitude, defined as living at an altitude of 2400 m or more above sea level. Subjects living under these conditions are continuously living under hypoxic conditions and, depending on ...
