A 58 year old type 1 diabetic on anti hypertensive therapy for 13 years developed central chest pain for 45 minutes while driving along with cold sweating and dyspnea. What is the single most appropriate diagnosis?

The key is A. MI. [In pericarditis pain is aggravated by inspiration or lying flat and relieved by leaning

forward. Pericardial rub may present and there may be fever. In pneumothorax pain is not central but

pleuritic. Pulmonary embolism=dyspnoea and pleuritic chest pain. In costrochondritis localized

pain/tenderness at the costochondral junction enhanced by motion, coughing, or sneezing. The given

picture of central chest pain for 45 minutes (more than 30 minutes), sweating and dyspnoea with major risk factor of DM and Htn suggest the diagnosis of MI].
