Depression is common and estimates suggest that in a family of four, one of the family members will likely suffer from mental health problems. Depression is even 3 times more common in patients after a heart attack than in the general population. Depression after a heart attack is bad not only because of the accompanying emotional distress, it also increases the risk of having another heart attack or premature death.
The CO-rebreathing technique for measuring total blood volume and hemoglobin mass is safe to perform in stable coronary artery disease patients having completed cardiac rehabilitation. Trine Karlsen and colleagues show this in a resent study ”Safety of the CO-Rebreathing Method in Patients with Coronary Artery Disease”, published in the Medicine and Science in Sports and Exercise Journal.
“The aim of the study was to investigate the use of this methodology in stable coronary artery disease patients to allow for an implementation of the methodology in this patient group”, Karlsen says. Knowledge of total blood volume and absolute hemoglobin mass is vital when evaluating cardiovascular physiology and function, as well as physical activity performance.
