Final answer:
The initial treatment for acute myocardial ischemia includes administering supplemental oxygen, aspirin, and sublingual nitroglycerine; followed by thrombolytics and other interventions like angioplasty or bypass surgery.
Step-by-step explanation:
The initial treatment for acute myocardial ischemia (MI), often referred to as a heart attack, revolves around the quick restoration of blood flow to the heart to minimize tissue damage. This involves the administration of supplemental oxygen, aspirin for its anticoagulant and antiplatelet effects, and nitroglycerine sublingually to take advantage of its vasodilatory properties. These immediate treatments are critical in managing the acute phase of MI, followed by further interventions such as thrombolytic therapy to dissolve clots, anticoagulants like heparin, and potentially invasive procedures like balloon angioplasty or bypass surgery in severe cases.
