Because it is associated with significant pain, high-risk patients likely to require pacing should receive a temporary pacemaker. Medical therapy Initial evaluation and management of suspected acute coronary syndrome myocardial infarction, unstable angina in the emergency department Nitrates in the management of stable angina pectoris Overview of the acute management of ST-elevation myocardial infarction Overview of the acute management of non-ST elevation acute coronary syndromes Right ventricular myocardial infarction Sexual activity in patients with cardiovascular disease Society guideline links: Concern exists about oral nitrate preparations in the patient with acute MI because of inability to titrate the dose to effect in an acutely evolving hemodynamic situation, whereas intravenous infusion of nitroglycerin can be titrated successfully with frequent measurement of heart rate and cuff blood pressure.

Use of nitroglycerin for the treatment of acute myocardial infarction. The vasodilator action of GTN was discovered as a process mediated by nitric oxide. George's, University of London.

The combination of t-PA and nitroglycerin not only decreased the plasma concentrations of t-PA, but also impaired the thrombolytic effects of t-PA. Hemodynamic effects of nitroglycerin and long-acting nitrates. Previous article in issue: National Center for Biotechnology InformationU. The initial evaluation of the patient ideally should be accomplished within 10 minutes of his or her arrival in the ED; certainly no more than 20 minutes should elapse before an assessment is made.

Only when mortality, extension of MI or occurrence of left ventricular failure were combined was there a benefit seen, but not individually.

Mitochondrial aldehyde dehydrogenase and cardiac diseases. Support Center Support Center. Once hospitalized, the patient with acute MI should be continuously monitored by electrocardiography and the diagnosis of acute MI confirmed by serial ECGs and measurements of serum cardiac markers of myocyte necrosis, such as creatine kinase isoenzymes or cardiac specific troponin T or I.

Acute MI with persistent or recurrent ischemia refractory to medical therapy in patients with coronary anatomy suitable for surgery who are not candidates for catheter intervention. Aldehyde dehydrogenase 2 plays a role in the bioactivation of nitroglycerin in humans. University of Alberta, Canada. This regimen is likely used out of convenience, ease of administration, and extrapolation of data based on the amount of nitroglycerin per minute that patients receive from SL dosage forms.

Larger studies are needed to determine if nitroglycerin can reduce mortality and further define the population who would benefit most from nitroglycerin. However, continuous delivery of nitroglycerin results in tolerance, limiting the use of this drug.
