Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
The variation in pressure in the left ventricle (blue line) and the aorta (red line) over two cardiac cycles ("heart beats"), showing the definitions of systolic and diastolic pressure Blood pressure is classified as normal blood pressure, prehypertension , hypertension (stages I and II), and isolated systolic hypertension , which is a common ...
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
In medicine, systolic hypertension is defined as an elevated systolic blood pressure (SBP). [1] If the systolic blood pressure is elevated (>140) with a normal (<90) diastolic blood pressure (DBP), it is called isolated systolic hypertension. [2] Eighty percent of people with systolic hypertension are over the age of 65 years old. [3] Isolated ...
Hypertension or high blood pressure affects at least 26.4% of the world's population. [15] Hypertensive heart disease is only one of several diseases attributable to high blood pressure. Other diseases caused by high blood pressure include ischemic heart disease, cancer, stroke, peripheral arterial disease, aneurysms and kidney disease.
In a study published in Arthritis & Rheumatology, researchers found the number one predictor of widespread pain, especially among adults over 50, is non-restorative sleep, or disruptive sleep ...
These diseases include pneumonia, ear infections, sinus infections, meningitis and blood infections, and older people (and children under 2) are at the greatest risk.
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
