Chewable isosorbide dinitrate provides a nitrate action of rapid onset and sustained effect that may be useful for chronic vasodilator therapy of heart failure. The newer organic nitrate, which has recently been evaluated, is pentaerythrityl tetranitrate. Location: Hypertension and Clinical Hemodynamics Section of the VA Hospital and Dept of Medicine at Georgetown University School of … Oral nitrates appear to improve activity tolerance in HF patients with reduced ejection fraction, but their effect in patients with HF-pEF is not known. Nitrate tolerance is a significant problem regarding chronic nitrate use. Although nitrates can be used in different forms (sublingual, oral, transdermal, IV), the most common route of administration in acute heart failure is IV.

In the majority of patients with stable ischemic heart disease (SIHD), long-acting nitrates are used as part of OMT to reduce the risk of cardiovascular morbidity (notably angina and myocardial ischemia) and thus, to enhance the quality of life by reducing symptoms 8 and improving exercise capacity. Long-acting nitrates dilate blood vessels, including the heart's own coronary arteries. Long-acting nitrates as oral tablets or sustained release transdermal patches are used for angina prophylaxis.

Nitrates can be used to prevent chest pain , limit the number of angina attacks that you have, relieve the pain of a current attack, or treat the symptoms of heart failure.

(Angina is usually caused by narrowing of the heart arteries due to a build-up of a fatty substance called atheroma. People often see nitrates and nitrites as harmful, but this may not always be true.

Current Practice and Recommendations Like all vasodilators, nitrates are contraindicated in the setting of hypotension, as well as in LV outflow tract obstruction, and in AHF mimics (e.g., chronic obstructive pulmonary disease) where vasodilation is unlikely to provide a benefit. From birth to adulthood - congenital heart disease; Heart failure and success, a change of heart ; ... By dilating the blood vessels of the heart, nitrates can reduce the stress on the heart by improving blood flow to the heart muscle. 1,2 CVD is associated with a decline in quality of life and an increase in disability, greatly increasing the cost of medical treatment.

AU - Koepp, Katlyn E. AU - Melenovsky, Vojtech The Vasodilatation in the Management of Acute Congestive Heart Failure (VMAC) study was a randomized, controlled AHF trial comparing nesiritide (the recombinant B-type natriuretic peptide) in 204 patients receiving either nitroglycerin (n=143) or placebo (n=142). Though nitrates and nitrites can be very problematic, nitrates are often prescribed for some people that have a heart condition. Angina pectoris ("heart pain") is due to an inadequate flow of blood and oxygen to the muscle of the heart.

Leafy greens may help protect the heart, new research suggests. Moreover, nitrates did not improve exercise capacity or symptoms of heart failure, such as shortness of breath and weakness when walking, according to Dr Redfield, and symptoms tended to be worse among those taking the drugs. Nitrates are primarily venodilators, which means the venous pressure will drop, and the amount of blood going to the right side of the heart will decrease.

Here is a summary of the study and the main results.
