Diastolic dysfunction is related with a preserved contraction of the heart, in which the heart ejects its volume sufficiently, but faces difficulty while relaxing adequately during the diastolic phase. As a result, the heart takes a longer time to fill up than usual, causing an increase in its filling pressure.
Uncontrolled diastolic dysfunction can lead to pulmonary congestion with the associated risk of heart failure and dyspnea.
Diastolic dysfunction is related with pulmonary congestion, risk of heart failure, and normal or near-normal levels of systolic pressure. It can cause shortness of breath, dyspnea, and lower leg edema.
The usual patients of diastolic dysfunction are elderly persons or people suffering from diabetes, heart disease, hypertension, and obesity.
Diastolic dysfunction may be mild, moderate, or severe. Diastolic Dysfunction Grade 1 is mild dysfunction, which represents the earliest stage of abnormality. It includes mild filling pressures, slightly raised left ventricular end diastolic pressure, and near normal resting mean left atrial pressure.
Diastolic Dysfunction Grade 2 is moderate abnormality that symbolizes the intermediate phase. It includes slightly raised left ventricular end diastolic pressure, associated with dyspnea and minor functional damage.
Diastolic Dysfunction Grade 3 denotes severe dysfunction, which signifies a stage of advanced abnormality. It is characterized by a substantial increase in left ventricular filling pressure, dyspnea with little exertion, and significant functional damage.
Diastolic Dysfunction Grade 4 is the most advanced and the last stage. It is marked by severe cardiac failure that remains uncontrolled despite regular treatment. In this stage, the filling pressures and the filling patterns correlate.
The treatment of diastolic dysfunction usually involves the use of ACE inhibitors, beta-blockers, calcium channel blockers, and ARBs.
As this condition is widely prevalent among the elderly people, it may pose a potential health hazard as the current youth population ages. So, it is extremely important this condition be diagnosed and treated well in time.
