Document Summary
It is under-reported as there are no symptoms and if untreated, risk of. Cad increases 3x and risk of stroke increases 7x. Highest in some ethnic groups including: blacks, first nations, north americans of mexico, puerto rican decent, cuban decent. Determinants: advancing age hbp and its associated co-morbidities (heart failure, cvd, stroke, renal disease etc. ) increases with age, black race, hx of cvd, inactivity, overweight/obese and alcohol consumption. Mean arterial pressure = flow (q) x tpr. Cardiac output (l/min) = hr (bpm) x sv (ml/beat) Note: q or flow is the same as cardiac output, this is the blood flow through the system. Vascular resistance: resistance (arbitrary units, pru) is determined by degree of dilation or constriction of blood vessels. Resting: co: 70bpm x 0. 7 l/beat = 4. 9 l/min, sbp: 120 mmhg, dbp: 80 mmhg, map: 93 mmhg, tpr = map/q 93/5 = 18. 6 pru. Bp is easily measured with a sphygmomanometer.
