Chest pain management in acute coronary syndrome and chronic stable angina with diluted xylocaine injections.

Pain following myocardial ischemia is a significant clinical concern, contributing to increased sympathetic tone, mortality and morbidity. Standard management includes beta blockers, nitrates, aspirin-clopidogrel and opioids. We propose a robust pain portal block technique using 0.5% lignocaine at designated sites on the chest wall and upper limb. This method offers rapid and effective analgesia for both cardiac and non-cardiac chest pain, extending beyond lignocaine's typical duration of action. Early implementation of this technique may positively impact the management and outcomes of acute myocardial infarction.
