CARDIOPATIA ISQUEMICA.- I
Supplemental oxygen should be
administered to patients with arterial oxygen
desaturation (SaO2 < 90%).
It is reasonable to administer supplemental oxygen to all patients with uncomplicated STEMI during the first 6 hours.

Patients with ongoing ischemic discomfort should receive sublingual NTG (0.4 mg) every 5 minutes for a total of 3 doses, after which an assessment should be made about the need for intravenous NTG.
Intravenous NTG is indicated for relief of ongoing ischemic
discomfort that responds to nitrate therapy, control of
hypertension, or management of pulmonary congestion.

Nitrates should not be administered to patients who have received a phosphodiesterase inhibitor for erectile dysfunction within the last 24 hours (48 hours for tadalafil).
• systolic pressure < 90 mm Hg or ≥ to 30 mm Hg below baseline
• severe bradycardia (< 50 bpm)• tachycardia (> 100 bpm) or• suspected RV infarction.

Analgesia
Morphine sulfate (2 to 4 mg intravenously with
increments of 2 to 8 mg intravenously
repeated at 5 to 15 minute intervals) is the
analgesic of choice for management of pain
associated with STEMI.

Aspirin should be chewed by patients who
have not taken aspirin before presentation
with STEMI. The initial dose should be 162
mg (Level of Evidence: A) to 325 mg (Level
of Evidence: C)
Although some trials have used enteric-coated aspirin for initial dosing, more rapid buccal absorption occurs with non–enteric-coated formulations.

Oral beta-blocker therapy should be administered
promptly to those patients without a contraindication,
irrespective of concomitant fibrinolytic therapy or
performance of primary PCI.
It is reasonable to administer intravenous beta-
blockers promptly to STEMI patients without
contraindications, especially if a tachyarrhythmia or
hypertension is present.
