Left ventricular diastolic decompensation due to hypertension cannot be reversed. 1. Prolonged elevation of blood pressure leads to myocardial hypertrophy and enlargement of the cardiac chambers, resulting in a decrease in cardiac compliance, which in turn leads to a decrease in left ventricular diastolic function, a change that is often irreversible. 2. Even though the reduction in LV diastolic function is irreversible, effective control of hypertension can prevent or delay further myocardial damage, improve myocardial remodeling, and thus delay further decline or deterioration of cardiac function. Therefore, even if LV diastolic function is reduced, cardiac function can still be maintained within the normal range through effective control of blood pressure. The pathologic mechanisms of hypertension-induced left ventricular diastolic dysfunction are complex, and the possibility of reversal of left ventricular diastolic dysfunction caused by certain pathologic mechanisms cannot be ruled out.
