An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance. This is different from inotropes which increase the force of cardiac contraction. Some substances do both (e.g. dopamine, dobutamine).
Phenazopyridine is an azo dye. [17] [18] Other azo dyes, which were previously used in textiles, printing, and plastic manufacturing, have been implicated as carcinogens that can cause bladder cancer. [19] While phenazopyridine has never been shown to cause cancer in humans, evidence from animal models suggests that it is potentially ...
In hypertensive encephalopathy, generally the blood pressure is greater than 200/130 mmHg. [1] Occasionally it can occur at a BP as low as 160/100 mmHg. [4] This can occur in kidney failure, those who rapidly stop blood pressure medication, pheochromocytoma, and people on a monoamine oxidase inhibitor (MAOI) who eat foods with tyramine. [2]
Processed Foods Raise Blood Pressure. Yes, many ultra-processed foods (think doughnuts, candies and hot dogs) are not the best choices for our health. However, there are a surprising number of ...
A hypertensive emergency is not based solely on an absolute level of blood pressure, but also on a patient's baseline blood pressure before the hypertensive crisis occurs. Individuals with a history of chronic hypertension may not tolerate a "normal" blood pressure, and can therefore present symptomatically with hypotension , including fatigue ...
People with high blood pressure who slept for shorter durations were more likely to show poor cognitive function and increased levels of markers of brain aging and injury, a new study has found.
Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%. It can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. [2] There are many classes of antihypertensives, which lower blood pressure by different means.
Uncontrollable increase in blood pressure can cause damage to the arteries that are present around kidneys, and thus restrict the blood to deliver. Due to inconsistent fluctuations in blood pressure, this can cause additional problems to people with pre-existing heart or blood vessel conditions such as angina, cerebral aneurysm or aortic ...
