English term or phrase: loading conditions
Hypertrophic cardiomyopathy (HCM), an autosomal dominant genetic disease, is defined
clinically by the presence of increased left ventricular (LV) wall thickness associated with nondilated ventricular chambers that is not solely explained by abnormal ***loading conditions***, such as another cardiac or systemic disease

Preload and Afterload. The work that the heart performs consists
mainly of ejecting blood into the pulmonary or systemic
circulations. It is determined largely by the loading conditions
or what is called the preload and afterload.
Preload reflects the loading condition of the heart at the end
of diastole just before the onset of systole. It is the volume of
blood stretching the resting heart muscle and is determined
mainly by the venous return to the heart. Afterload represents
the force that the contracting heart must generate to eject blood
from the filled heart. The main components of afterload are
ventricular wall tension and the peripheral vascular resistance.
The greater the peripheral vascular resistance, the greater the
ventricular wall tension and intraventricular pressure required
to open the aortic valve and pump blood into the peripheral
circulation.
