Patient was educated on diastolic heart failure as follows:

1. Diastole is the phase of heartbeat when the heart relaxes and fills with blood. Diastolic heart failure is an inability of the heart to relax and accommodate inflow of blood into the chambers.
2. When the heart is in failure and not functioning optimally, fluid backs up in the pulmonary circulation and peripheral circulation. This results in increased pressure in pulmonary blood vessels and peripheral veins, resulting in fluid accumulation in the lungs, shortness of breath, and edema of the extremities.
3. If this situation is not controlled and the damage further continues, the heart cannot pump enough blood during the systole too, as the heart is not filling properly with blood during diastole, thus resulting in systolic heart failure.
4. So, poorly managed diastolic heart failure, over a period, can lead to systolic heart failure.
