In patients with acute ST-segment elevation myocardial infarction, the recommended dose of Lovenox is a single IV bolus of 30 mg plus a 1 mg/kg SC dose followed by 1 mg/kg administered SC every 12 hours (maximum 100 mg for the first two doses only, followed by 1 mg/kg dosing for the remaining doses).

It is also possible that a break in the fuel delivery lines is causing a loss of power to the engine, which causes engine sputtering.
