In 2004, an article in the [[BMJ]] examined the evidence for and against the suggestion that angiotensin receptor blockers may increase the risk of [[myocardial infarction]] (heart attack). The matter was debated in 2006 in the medical journal of the [[American Heart Association]]. There is no consensus on whether ARBs have a tendency to increase MI, but there is also no substantive evidence to indicate that ARBs are able to reduce MI. | In 2004, an article in the [[BMJ]] examined the evidence for and against the suggestion that angiotensin receptor blockers may increase the risk of [[myocardial infarction]] (heart attack).

In the VALUE trial, the angiotensin II receptor blocker valsartan produced a statistically significant 19% (p=0.02) relative increase in the prespecified secondary end point of myocardial infarction (fatal and non-fatal) compared with [[amlodipine]]. | In the VALUE trial, the angiotensin II receptor blocker valsartan produced a statistically significant 19% (p=0.02) relative increase in the prespecified secondary end point of myocardial infarction (fatal and non-fatal) compared with [[amlodipine]]. | ||

[[Vasodilator]]s act directly on the [[smooth muscle]] of arteries to relax their walls so blood can move more easily through them; they are only used in [[hypertensive emergency|hypertensive emergencies]] or when other drugs have failed, and even so are rarely given alone. | [[Vasodilator]]s act directly on the [[smooth muscle]] of arteries to relax their walls so blood can move more easily through them; they are only used in [[hypertensive emergency|hypertensive emergencies]] or when other drugs have failed, and even so are rarely given alone. | ||
[[Sodium nitroprusside]], a very potent, short-acting vasodilator, is most commonly used for the quick, temporary reduction of blood pressure in emergencies (such as [[malignant hypertension]] or [[aortic dissection]]).[[Hydralazine]] and its derivatives are also used in the treatment of severe hypertension, although they should be avoided in emergencies. They are no longer indicated as first-line therapy for high blood pressure due to side effects and safety concerns, but hydralazine remains a drug of choice in [[gestational hypertension]]. | [[Sodium nitroprusside]], a very potent, short-acting vasodilator, is most commonly used for the quick, temporary reduction of blood pressure in emergencies (such as [[malignant hypertension]] or [[aortic dissection]]).[[Hydralazine]] and its derivatives are also used in the treatment of severe hypertension, although they should be avoided in emergencies.
