Antihypertensive. Antihypertensives are a class of drugs that are used to treat hypertension (high blood pressure). [1] Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can ...
Hydralazine. Hydralazine, sold under the brand name Apresoline among others, is a medication used to treat high blood pressure and heart failure. [2] This includes high blood pressure in pregnancy and very high blood pressure resulting in symptoms. [3] It has been found to be particularly useful in heart failure, together with isosorbide ...

The term hypertensive emergency is primarily used as a specific term for a hypertensive crisis with a diastolic blood pressure greater than or equal to 120 mmHg or systolic blood pressure greater than or equal to 180 mmHg. [10] Hypertensive emergency differs from hypertensive urgency in that, in the former, there is evidence of acute ...
Flicker vertigo. Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [1] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of ...
By reducing alpha-1-adrenergic activity of the blood vessels, these drugs may cause hypotension (low blood pressure) and interrupt the baroreflex response. In doing so, they may cause dizziness, lightheadedness, or fainting when rising from a lying or sitting posture (known as orthostatic hypotension or postural hypotension). For this reason ...
Coronary steal. Coronary steal (with its symptoms termed coronary steal syndrome or cardiac steal syndrome) is a phenomenon where an alteration of circulation patterns leads to a reduction in the blood flow directed to the coronary circulation. [1] It is caused when there is narrowing of the coronary arteries and a coronary vasodilator [2] is ...
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
Heavy-headedness is the feeling of faintness, dizziness, or feeling of floating, wooziness. [1][2][3] Individuals may feel as though their head is heavy; also feel as though the room is moving/spinning also known as vertigo. Some causes of heavy-headedness can be tough to get rid of and can last a long period of time, however most can be treated.
