Hemodynamics of the LV under Baseline condition 4 weeks after MI.

Hemodynamics of the LV under Stress condition 4 weeks after MI.Values are represented as Mean ± SEM, Pmax means maximum pressure; dp/dt indicates peak rate of maximum pressure rise (dp/dt max) and decline (−dp/dt max); EDV, enddiastolic volume; ESV, endsystolic volume; SV, stroke volume; EF, ejection fraction; and HR, heart rate.MI-Magnet+MNBs/Ad group: a rat myocardial infarction model, a 6×2×2 mm cylindrical NdFeB magnet (Br: ≈1000 mTesla) (IBS, Germany) was placed in the chest of the rat closely adjacent to the infarcted area of the heart and intravenously injected MNBs/Ad complexes.MI-Magnet−MNBs/Ad group: a rat myocardial infarction model, a similar size ceramic bar was placed in the chest of the rat closely adjacent to the infarcted area of the heart and intravenously injected MNBs/Ad complexes.MI-MNBs group: a rat myocardial infarction model, a 6×2×2 mm cylindrical NdFeB magnet (Br: ≈1000 mTesla) (IBS, Germany) was placed in the chest of the rat closely adjacent to the infarcted area of the heart and intravenously injected MNBs.Saline group: a rat myocardial infarction model and intravenously injected 0.9% NaCl.
