Diastolic Heart Failure: The Pathophysiology Of Diastolic Heart Failure As Well As Factors Associated With This Threatening Problem

By Dimitry Koub


Diastolic dysfunction is broken down as per the areas of blood flow. The left ventricle pumps blood via a systemic way which is the whole body along with the right ventricles pumps blood to pulmonary system that is the lungs.

Diastolic dysfunction is broken down as per the areas of blood flow. The left ventricle pumps blood via a systemic way which is the entire body along with the right ventricles pumps blood to pulmonary system which happens to be the lungs. The left ventricle receives the blood coming from the left atrium, pumps the oxygenated blood out of the heart and also distributes all over the entire body. The right ventricle that gets the deoxygenated blood from the right atrium, pumps the blood going to the pulmonary artery, and then to the lungs. The cycle keeps on continuing. At the left side of the heart, it generally loads forward an optimum of 60 to 80 times in every single minute without any blockage from the lungs. After that the blood passes to the pulmonary vein, and then to left atrium, finally the left ventricle. If the left ventricle can't fill normally because of its damage, the pressure reverses. Therefore the blood regurgitates back into the left atrium. And then the blood will regurgitate to the pulmonic veins thereafter to the lungs. This will cause pulmonary hypertension. This problem will soon develop into pulmonary edema when left untreated. Pulmonary edema is caused by over loading of alveolar vessels with fluid a result of regurgitated blood. Diastolic dysfunction plus pulmonary hypertension usually means a heart failure with a typical discharge fraction. The left ventricle gets stiff enough that the blood flowing from it will have trouble in entering, as a result the blood will flow back to the right atrium. And then the blood will flow backwards towards the pulmonary vein and also entering the lungs. The lungs will be filled by an excessive amount blood repeatedly as the process goes on. The outcome would be an increase in hydrostatic pressure where the fluid coming out via the pulmonic vein leaks into the alveolar compartments of the lungs resulting in pulmonary edema. Pulmonary edema is an obstruction condition. Patients with this type of problem will experience problems of breathing. This condition is really deadly when neglected. This pressure reversal will lead to pressure mismatch. The pressure mismatch continues its process in an unusual way resulting in pathologic deformation of the heart chambers. A number of heart disease may happen, for example the mitral valve prolapsed along with other valvular problems.

This disorder impacts the anatomy of the heart. The heart shows overgrowth of cardio myocytes, increase in the collagen deposit, along with the infiltration of myocardium. The myocardium will be distended. The heart looses it capability to contract and also fill blood in the optimum level resulting in decrease of cardiac output, tremendous increase in diastolic pressure, and also increase in pulmonary vein pressure, alveolar edema.

Diastolic dysfunction has symptoms and signs that involve elevation of diastolic pressure of the left ventricle even though the end diastolic volume is regular. The affected individual will also experience breathing difficulties and also dizziness.

The risk issues for diastolic dysfunction are the following: hypertension, the elevation of blood pressure; Aortic stenosis brought on by hypertension; Scarred heart muscle the result of earlier heart attack; Diabetes as the heart muscles become stiff from glycosylation; Extreme systolic dysfunction from increased ventricular pressure as a consequence of dilatation; and reversible stiffening because of ischemia.
