Normally, de-oxygenated venous blood from the body goes into the right atrium of the heart. If this high pressure continues, it puts a strain on the right side of the heart. J Nucl Med. 1986 Oct. 78(4 Pt 2):793-9. Risk factors associated with chronic obstructive pulmonary disease early readmission. The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved), however most of the time, the right ventricle adjusts to an overload in chronic pressure. This makes it harder for the heart to pump blood to the lungs.
