Heart disease is the leading cause of mortality in the United States. One cause of heart arrhythmia is calcium (Ca2+) mishandling in cardiac muscle cells. We adapt Izu's mathematical model (Izu, 2006), implemented by Gobbert (Gobbert, 2008), of cardiac muscle cells, or cardiomyocytes, to include calcium being released from the sarcoplasmic reticulum (SR), the effects of buffers in the SR, particularly calsequestrin, and the effects of Ca2+ influx due to voltage across the cell membrane. The mathematical model is coded in C, run using parallel computing (MPI) to efficiently generate simulations of the model, and post-processed in Matlab. Based on computer code and simulations, our findings aligned with known biological models and principles, giving us a thorough understanding of several factors that influence Ca2+ dynamics in cardiac myocytes.
