Cardiovascular health is of utmost importance, and the rapid evolution of monitoring devices and applications has revolutionized the way we manage it. From smartwatches to electrocardiogram (ECG) devices and implantable solutions, these technological advancements aim to improve patient outcomes. However, the integration of patients' health information with technology necessitates stringent measures to protect personal health information (PHI) and ensure compliance with the Health Insurance Portability and Accountability Act (HIPAA). This study investigates the compliance of various cardiovascular health management (CHM) software, applications, and systems with HIPAA regulations. Through an extensive literature review and systematic analysis, we assessed over 25 scholarly articles that discuss the intersection of cardiovascular health monitoring devices and HIPAA compliance. Our evaluation of the current state of compliance across different applications revealed both strengths and weaknesses in the industry’s privacy and security measures. Our findings indicate that although many CHM solutions demonstrate compliance with HIPAA regulations, there remain areas of concern, particularly regarding data encryption, storage, and access control. To address these gaps, we propose specific recommendations for enhancing privacy and security, including the adoption of robust encryption methods, strict access control policies, and regular security audits. Future research should focus on the development of standardized compliance frameworks for cardiovascular health management systems, as well as the assessment of emerging technologies and their potential impact on HIPAA compliance. By advancing our understanding of the challenges and opportunities in this field, we aim to contribute to the ongoing efforts to protect patients' PHI and promote secure, reliable, and effective health management solutions.

Interoperability remains one of the biggest challenges facing healthcare organizations today. Despite the advancements made through digital transformation and API that allow increased interoperability, patients still have to contend with a different patient portal for each provider they visit. Several health systems are unable to successfully exchange EHR data. API transfer and consolidate patient information including medical history and treatment records across the disparate health care systems. Mobile apps use API to gather data from various medical wearables and add the data to a patient's health record. However, API exposes application logic and sensitive data information giving patient data a window to the World Wide Web and has thus increasingly become a target for attackers. As the need for tighter API security grows, managing APIs becomes more important than ever. The goal of this paper is to provide an overview and discuss research questions that can aid in understanding and building the knowledge base on API data integration and interoperability.
