Cardiac Rehabilitation: A Literature Review of Benefits, Challenges, and Emerging Approaches.

Abstract

Cardiac rehabilitation (CR) plays a vital role in the management of cardiovascular diseases (CVDs), such as ischemic heart disease and heart failure, which remain major causes of illness and death worldwide. This literature review explores recent progress and future directions in CR, highlighting its importance as a comprehensive and multidisciplinary approach. Modern programs now combine exercise training, nutritional guidance, psychosocial support, and lifestyle modification to improve recovery and prevent further cardiac events. The inclusion of technology, such as mobile health apps, wearable monitors, and virtual rehabilitation programs, has made CR more accessible and effective for diverse patient groups. Despite strong evidence showing that CR reduces mortality, improves functional capacity, and enhances quality of life, participation rates remain low. Barriers often include limited availability of programs, low referral rates, and challenges linked to socioeconomic and cultural factors. Addressing these issues requires practical strategies to improve awareness, accessibility, and patient adherence. Future research should focus on developing culturally adaptable and technology-driven models of CR that reach more patients and deliver long-term health benefits.
