Overview
Administration of nitroglycerin is the standard of care for patients presenting with acute coronary syndrome. If three sublingual 0.4mg tablets of NTG fail to relieve the pain, intravenous NTG may be initiated along with oral or intravenous beta blocker. It is also be helpful in patients with heart failure and hypertension.
Mechanism of Benefit
- Nitroglycerin (NTG), an endothelium-independent vasodilator, has both peripheral and coronary vascular effects.
- By venodilation, it decreases the myocardial preload, ultimately, decreasing the myocardial oxygen demand.
- It also dilates the coronary arteries, thus, decreasing the amount of stenosis and relieves pain.
- In addition, it promotes collateral flow and redistribution of coronary blood flow to ischemic regions.

Class I |
"1. Patients with NSTE-ACS with continuing ischemic pain should receive sublingual nitroglycerin (0.3 mg to 0.4 mg) every 5 minutes for up to 3 doses, after which an assessment should be made about the need for intravenous nitroglycerin if not contraindicated. (Level of Evidence: C)" |
"2. Intravenous nitroglycerin is indicated for patients with NSTE-ACS for the treatment of persistent ischemia, HF, or hypertension. (Level of Evidence: B)" |
Class III |
"1. Nitrates should not be administered to patients with NSTE-ACS who recently received a phosphodiesterase inhibitor, especially within 24 hours of sildenafil or vardenafil, or within 48 hours of tadalafil. (Level of Evidence: B)" |

"2. Intravenous NTG is indicated in the first 48 h after Unstable angina / NSTEMI for treatment of persistent ischemia, heart failure, or hypertension.

Class III |
"1. Nitrates should not be administered to Unstable angina / NSTEMI patients with systolic blood pressure <90mmHg or ≥30 mmHg below baseline, severe bradycardia (<50 bpm), tachycardia (>100 bpm) in the absence of symptomatic heart failure, or right ventricular infarction. (Level of Evidence: C)" |
"2. Nitroglycerin or other nitrates should not be administered to patients with Unstable Angina / NSTEMI who had received a phosphodiesterase inhibitor for erectile dysfunction within 24 h of sildenafil or 48 h of tadalafil use. The suitable time for the administration of nitrates after vardenafil has not been determined. (Level of Evidence: C)" |
