Question

Which conditions would likely lead to diastolic heart failure?

Answer 1

Heart failure is a clinical syndrome which can  results from any functional or cardiac disoder that impairs the ability of the ventricles to fill or pump enough blood to meet the body's oxygen and nutrient requirements.

Diastolic heart failure is an abnormal stiffening of the ventricles, and thre resulting abnormal ventricular filling during diastole. These stiff ventricles cannot fully relax during diastole, and as a result ventricles may not fill completely, and blood can obstructs n the body's organ mainly the lungs.

Diastolic heart failure is present when diastolic dysfunction is sufficient to produce pulmonary congestion.

Following are the conditions that causes diastolic heart failure :

# Cardiac ischemia: It occurs when myocardial oxygen deemand exceeds myocardial oxygen supply.

# Hypertension: Increase in the diasolic B.P increases the risk of diastolc heart failure.

# Aging: As age advanced the walls in the arteries get narrows and the blood flow decreases.

# Obesity: It increases the risk of atherosclerosis

# Aortic stenosis: There is narrowing of the aortic valve opening which restricts the blood flow from the left ventricle to the aorta and affect the pressure in the left atrium.

# Pericardial disorders: Such as pericarditis and pericardial effusion can also cause diastolic heart failure.
