Do CHF patients take nitroglycerin?

Intravenous nitroglycerin is frequently used to treat acute coronary syndromes, hypertensive emergency, and acute congestive heart failure (CHF) exacerbations.

Why do we give nitroglycerin for CHF?

How does it work? Nitrates are vasodilators, which means they help widen (dilate) your blood vessels, making it easier for blood to flow through and let more oxygen-rich blood reach your heart. Better blood flow means your heart doesn’t have to work as hard.

How should SL nitroglycerin be taken for CHF?

Adults—1 tablet placed under the tongue or between the cheek and gum at the first sign of an angina attack. 1 tablet may be used every 5 minutes as needed, for up to 15 minutes. Do not take more than 3 tablets in 15 minutes. To prevent angina from exercise or stress, use 1 tablet 5 to 10 minutes before the activity.

What are the contraindications of nitroglycerin sublingual?

Nitroglycerin is contraindicated in patients who are allergic to it. Sublingual nitroglycerin therapy is contraindicated in patients with early myocardial infarction, severe anemia, increased intracranial pressure, and those with a known hypersensitivity to nitroglycerin.

Does nitroglycerin increase cardiac output?

NTG induced sustained reductions in LV dimensions and transient increases in heart rate and dP/dt, and decreases in mean arterial pressure. Initially NTG increased cardiac output and flows to the coronary, mesenteric, renal, and iliac beds, while systemic and regional vascular resistances fell.

How does nitroglycerin help with pulmonary edema?

Nitroglycerin (NTG) is an important intervention to consider for patients with Sympathetic Crashing Acute Pulmonary Edema (SCAPE) as it significantly reduces preload, and even modestly reduces afterload with high doses.

When is nitroglycerin contraindicated?

Nitroglycerin is contraindicated in patients that have reported allergic symptoms to the medication. [18] Known history of increased intracranial pressure, severe anemia, right-sided myocardial infarction, or hypersensitivity to nitroglycerin are contraindications to nitroglycerin therapy.

Does nitroglycerin cause tachycardia?

Other than hypotension, the side effects of nitroglycerin are minimal. Reflex tachycardia can occur but is usually slight. There may be a dose-dependent fall in arterial oxygen saturation due to inhibition of hypoxic pulmonary vasoconstriction.

When should you take nitroglycerin sublingual?

Nitroglycerin comes as a sublingual tablet to take under the tongue. The tablets is usually taken as needed, either 5 to 10 minutes before activities that may cause attacks of angina or at the first sign of an attack.

Does nitroglycerin raise heart rate?

The rise in heart rate began 1-1.5 min after administration of nitroglycerin tablets and was maximal within 3 min. The effect was more rapid with a quickly dissolving compound.

Does nitroglycerin decrease cardiac output?

Does Nitro help pulmonary hypertension?

Nitroglycerin has theoretic appeal as a vasodilator drug in patients with pulmonary hypertension because it exerts a direct effect on the pulmonary circulation in doses that do not affect systemic resistance vessels or the myocardium and do not activate neurohumoral reflexes.
