What Is Normal Blood Pressure?

Blood pressure is primarily produced when the heart muscle contracts - it is the pressure of blood upon the walls of the blood vessels. There are two recordings, a high one (systolic) and a lower one (diastolic). The systolic pressure is measured when the heart contracts, while the diastolic one is gauged just before the heart contracts. The heart is the muscle that pumps blood throughout the body during every second of our lives. Low-oxygen blood is pumped towards the lungs, where it becomes oxygen-rich again. Oxygen-rich blood is pumped by the heart around to body to supply tissue, muscle, organs and cells. This pumping generates blood pressure. According to Medilexicon's medical dictionary, Blood Pressure is: "The pressure or tension of the blood within the systemic arteries, maintained by the contraction of the left ventricle, the resistance of the arterioles and capillaries, the elasticity of the arterial walls, as well as the viscosity and volume of the blood; expressed as relative to the ambient atmospheric pressure." Hypertension is when our blood pressure is too high, while hypotension is the opposite; it is when our blood pressure is too low. Taking a blood pressure measurement Most of us have had our blood pressure taken at some time in our lives. The procedure is straightforward and provides the doctor or other health care professional with vital data regarding the condition of the patient's blood vessels and heart. As mentioned above, two blood pressure readings are measured: The Systolic Pressure - this is the maximum pressure in an artery. It occurs when the heart contracts; when it is beating, and blood is being pumped through. The Diastolic Pressure - this is...

Statins Work As Well On Females As Males

Statins given to female patients are as effective in preventing the occurrence of cardiovascular events as they are for men, researchers from Boston and New York reported in the Journal of the American College of Cardiology. Cardiovascular events include stroke, heart attack, andangina. William J. Kostis, Ph.D., M.D., from Harvard Medical School, and team set out to determine what impact statins might have on reducing cardiovascular event risk in male and female patients. They gathered and analyzed data on 18 clinical trials which had gender-specific outcomes. A total of 141,235 patients were involved in all the studies, of which 40,275 were female - there were a total of 21,468 cardiovascular events. They found that those who were prescribed (randomly) statins had a considerably lower risk of a cardiovascular event compared to those on a placebo, usual care, or low-dose statin therapy. Females Odds Ratio were similar to men's - Odds Ratio: 0.81, 95% CI: 0.75 to 0.89; p < 0.0001, and Odds Ratio: 0.77, 95% CI: 0.71 to 0.83, p < 0.0001, respectively. The authors explained that the benefits of statins, regardless of the baseline risk, or type of control, were similar for males and females. All cause mortality was also considerably lower for both the male and female patients who were on statin therapy. In the same journal, the authors concluded in an Abstract: "Statin therapy is associated with significant decreases in cardiovascular events and in all-cause mortality in women and men. Statin therapy should be used in appropriate patients without regard to sex." What are statins? Statins, also known as HMG-CoA reductase inhibitors, belong to a class of medications that are...
