Final answer:
In treating MI, nitroglycerine is used but with caution in cases of inferior wall MI or right ventricular infarction due to potential reduction in preload and cardiac output. Other MI treatments include supplemental oxygen, aspirin, thrombolytics, anticoagulants, and various cardiac procedures or devices.
Step-by-step explanation:
In the treatment of myocardial infarction (MI), nitroglycerine is commonly administered sublingually because of its vasodilatory effects due to the release of nitric oxide. However, caution is advised in the case of an inferior wall MI or right ventricular infarction because these conditions can be associated with right ventricular dependency for maintaining adequate blood pressure and cardiac output. Nitroglycerine can lower preload and therefore reduce cardiac output in these patients; hence, its use should be carefully considered and monitored. Other treatments for MI include supplemental oxygen, aspirin, thrombolytic agents such as streptokinase, anticoagulants like heparin, and procedures such as balloon angioplasty, stent placement, and bypass surgery. Extensive damage may require more advanced interventions like a coronary replacement or the assistance of a coronary assist device.
