What does diastolic blood pressure represent?

Diastolic blood pressure represents the lowest number in blood pressure readings. It indicates the pressure in the arteries when the heart is in a state of relaxation and filling with blood between beats. This phase, known as diastole, is when the heart is not actively pumping blood, allowing the arteries to remain under a certain baseline pressure. Recognizing diastolic blood pressure is crucial for understanding cardiovascular health, as it reflects the resistance of the blood vessels and can indicate whether they are functioning properly when at rest. Being aware of both systolic (the highest number) and diastolic pressures is essential for assessing overall blood pressure health.
