Pulse pressure. Learn how to measure it, why it matters, and how to lower it with lifestyle changes. Pulse pressure is highly dependent on stroke volume, and is therefore influenced by all factors which determine stroke volume (preload, afterload and contractility). As the left ventricle ejects blood into the aorta, the aortic pressure increases to its peak systolic value. Blood oxygen levels fluctuate with activity, sleep, and various health problems. Blood vessels can be thought of as a plumbing system, and they can widen or constrict to control blood pressure. Elevated PP is increasingly being recognized as a risk factor for cardiovascular, particularly coronary, disease.
