QuestionChoice
Dilated cardiomyopathy is a disease which causes the stretching of heart muscles and results in the enlargement of ventricles and thinning of the heart muscle wall. This results in reduced contraction strength and, therefore, reduced cardiac output.

Dilated cardiomyopathy
QuestionChoice
Hypertrophic cardiomyopathy describes the enlargement of the muscle wall of the heart. This leads to diastolic heart failure as the ventricles are not able to fill as much and, therefore, cardiac output is reduced.

c
Hypertrophic cardiomyopathy
QuestionChoice
Restrictive cardiomyopathy leads to diastolic heart failure as it reduces the capacity of the heart to fill with blood, therefore, reducing the cardiac output

d
Restrictive cardiomyopathy
QuestionChoice
Aortic stenosis leads to diastolic heart failure. This is due to the valves blocking the outflow of blood from the left ventricle and, therefore, reducing cardiac output

Aortic stenosis
QuestionChoice
Cor pulmonale describes abnormal enlargement of the right side of the heart. This is due to hypoxia resulting in pulmonary arteriole constriction and hypertension.

Heart failure describes a situation where the cardiac output fails to supply enough blood to organs to fulfil their demand.

Which of the following is an example of systolic left-sided heart failure?
