The line between normal and raised blood pressure is not fixed and depends on your individual circumstances. The heart is a muscle that is designed to constantly pump blood around the body. It pumps blood that is low in oxygen towards the lungs, through the venous 'pipeline' veinswhere it receives a fresh supply of oxygen.
Blood pressure consists of two numbers. Systolic pressure, the force exerted on blood vessels when the heart beats, is the upper number. But your coronary arteries are different; they are surrounding the aortic valve, so they get blood only when the aortic valve closes — and that happens in diastole.
A plant-based diet can reduce blood pressure and lower the risk for heart disease. High blood pressure, or hypertension, wreaks havoc on the heart and kidneys. Carrying excess weight tends to raise the risk of developing high blood pressure, as the heart must work harder to pump blood around the body. Controlling your blood pressure is very important, and treatment often involves taking medication.
This document contains recommendations that can help you talk to your doctor and other health care professionals about your blood pressure. High blood pressure is one of the leading causes of death in Canada.

High blood pressure is the number one risk factor for stroke and a major risk factor for heart disease. High blood pressure is when the blood pressure in your arteries is elevated and your heart has to work harder than normal to pump blood through the blood vessels. It is important that you have your blood pressure checked regularly by your healthcare provider.
I have normal systolic blood pressure, but my diastolic goes between 82 and 96 during the work day and goes down to normal at night or when there is no stress. Should I be concerned or is this normal? If you don't have other health issues that increase your risk of cardiovascular problems, the situation you describe — isolated diastolic hypertension — isn't dangerous now.
