What Causes Diastolic Dysfunction?
Thanks for the question; in essence, diastolic dysfunction is caused by the inability of the heart to relax appropriately during diastole, the part of the cardiac cycle when the ventricles or pumping chambers of the heart should relax and get filled. overweight, advancing age, female gender, atrial fibrillation and particularly long standing hypertension have been implicated as risk factors.
The mainstays of treatment are good control of blood pressure low salt diet, sometimes diuretics are needed to help with fluid retention; beta blockers such as metoprolol or carvedilol are used to help the heart relax. Some also try nitrates such as isosorbide so that the load of blood to the ventricles is not so heavy.
