Literature Review Ideas- Help


Hello. I am a graduate student enrolled in an MSN program. I'm having trouble deciding on a literature review topic for my research class. The literature review for my research class will hopefully become part of my scholarly project, so the topic needs to be something I'm interested in and that can be researched. I'm really having a hard time coming up with problems though. Can someone please give me a few ideas? I am really interested in cardiology and health disparities. I would appreciate any ideas. Thank you!
