Finish your BSN, and pursue experience in cardiology. Consider your preferred area of specialty. Keep in mind that NPs interested in pediatric cardiology may also be called upon to manage the care of adults with congenital heart problems, so an FNP may be more useful than a PNP. Find a challenging NP MSN program in your desired specialty. Network with other NPs in cardiology to make it easier to find a wide variety of preceptorship opportunities. Consider the DNP program.
