Nitroglycerin, also known as glyceryl trinitrate (GTN), is a vasodilator used for heart failure, high blood pressure (hypertension), anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart or due to the recreational use of cocaine.
Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
Heart disease and cardiovascular disease have almost the same meaning. ... Nitroglycerin. Statins and other cholesterol-lowering drugs. Calcium channel blockers. Long-acting nitrates.
Nitrates, like nitroglycerin, dilate blood vessels, which is beneficial against myocardial ischemia in two ways: By increasing blood flow in the coronary arteries and the amount of oxygen that arrives to heart muscle; and by relaxing all blood vessels in the body, thereby reducing the workload that heart needs to produce against them and the ...
This vasodilation does not decrease the volume of blood the heart pumps, but rather it decreases the force the heart muscle must exert to pump the same volume of blood. Nitroglycerin pills, taken sublingually (under the tongue), are used to prevent or treat acute chest pain.
One of the most common forms of heart failure happens when the left heart ventricle (responsible for pumping oxygen-rich blood to the rest of the body) can’t effectively do its job.
People with a history of cardiovascular disease, heart problems, a previous heart attack, as well as those currently using nitrates like nitroglycerin or other medications for pulmonary arterial ...
The most important effect in angina is the widening of veins, which increases their capacity to hold blood ("venous pooling") and reduces the pressure of the blood returning to the heart (the preload). Widening of the large arteries also reduces the pressure against which the heart has to pump, the afterload. Lower preload and afterload result ...
