Pressure overload
Pressure overload refers to the pathological state of
myocardial ischaemia or, in extreme cases, outflow obstruction.[1]
Signs and symptoms
A forceful
pulmonary stenosis. Pulmonary hypertension is also associated with chronic lung disease. Coarctation of the aorta presents with a significant difference in blood pressure between the upper and lower limbs, a systolic murmur
or radiofemoral delay.[citation needed]
Causes
Any obstruction to the outflow of one of the chambers of the heart can lead to pressure overload.
Left ventricular pressure overload
Right ventricular pressure overload
- Pulmonary stenosis
- Pulmonary hypertension
Treatment
Treatment will depend on the underlying cause. However, in general, symptomatic relief from pressure overload will not be achieved immediately, but will involve a delayed response following the atrophy of the hypertrophied heart muscle.[citation needed]
