Abstract:
Coronary artery disease (CAD) remains a leading cause of mortality worldwide, with
obesity being a significant risk factor that exacerbates CAD outcomes. Exercise-based cardiac
rehabilitation (CR) has emerged as a crucial intervention for managing CAD, offering benefits
such as reduced cardiovascular mortality and improved health-related quality of life (HRQoL).
This review aims to evaluate the clinical effectiveness and cost-effectiveness of exercise-based
CR in patients with CAD, including those with obesity, focusing on quality of life and
cardiovascular outcomes.
Keywords:
coronary artery disease, obesity, exercise-based cardiac rehabilitation, quality of life,
cardiovascular outcomes.
Introduction
Coronary artery disease is a major global health concern, responsible for a significant portion of
deaths worldwide. Obesity complicates CAD management due to its impact on exercise capacity
and metabolic health. Exercise-based CR has evolved from exercise-only programs to
comprehensive secondary prevention programs that address lifestyle-related behaviors, including
weight management and risk factor modification.
Background
Exercise-based CR is designed to enhance cardiovascular health by mitigating risk factors
associated with CAD, such as hypertension, high cholesterol, and smoking. Obesity, being a
behavioral condition, requires a comprehensive behavioral approach for effective management.
Studies have shown that obese patients with CAD can benefit from CR, although improvements
in exercise capacity may be less pronounced compared to non-obese patients. CR typically
involves supervised exercise sessions, lifestyle counseling, and education on heart-healthy
behaviors.
Objectives
This review aims to assess the clinical effectiveness of exercise-based CR compared to no
exercise in patients with CAD, including those with obesity, focusing on quality of life and
cardiovascular outcomes. The study involves a randomized clinic trial of 80 participants.
Literature Review
Impact of obesity on CAD
Obesity is a significant risk factor for CAD, contributing to insulin resistance and metabolic
syndrome. These factors exacerbate CAD outcomes by reducing exercise capacity and increasing
cardiovascular risk factors. Effective management of obesity is crucial for improving CAD

outcomes.
Exercise-Based CR
Exercise-based CR has evolved from simple exercise programs to comprehensive secondary
prevention strategies. These programs include supervised exercise, lifestyle counseling, and
education on heart-healthy behaviors. They aim to improve cardiovascular health by reducing
risk factors associated with CAD.
Benefits of exercise-based CR
Exercise-based CR offers several benefits for patients with CAD, including improved HRQoL,
reduced cardiovascular mortality, and enhanced physical function. It also helps in managing risk
factors such as hypertension and high cholesterol. Recent studies confirm that CR reduces
cardiovascular mortality by approximately 26% and hospital readmissions by 18%.
Effectiveness in obese patients
While obese patients may experience less pronounced improvements in exercise capacity
compared to non-obese patients, they still benefit significantly from CR. The comprehensive
approach of CR helps in managing obesity-related factors that complicate CAD management.
Cost-Effectiveness
Exercise-based CR is not only clinically effective but also cost-effective. By reducing hospital
readmissions and improving long-term health outcomes, CR can lead to significant cost savings
in healthcare systems.
Methodology
This review involves a systematic search of major databases to identify studies focusing on the
clinical effectiveness of exercise-based CR in patients with CAD, including those with obesity.
A randomized clinical trial of 80 participants was conducted to assess the impact of exercise-
based CR on quality of life and cardiovascular outcomes.
Participants
The study included 80 patients with CAD, divided into two groups: those receiving exercise-
based CR and those receiving standard care without exercise. Participants were aged between 40
and 70 years and had a confirmed diagnosis of CAD.
Intervention
The exercise-based CR program consisted of supervised exercise sessions three times a week for
six months. Each session included aerobic exercise, strength training, and flexibility exercises.
Participants also received lifestyle counseling and education on heart-healthy behaviors.
Outcome measures
Primary outcomes included changes in HRQoL, measured using the SF-36 questionnaire, and
cardiovascular outcomes, such as reduction in blood pressure and cholesterol levels. Secondary
outcomes included improvements in exercise capacity and weight management.
Results
The results of the randomized clinical trial showed significant improvements in HRQoL and

cardiovascular outcomes among participants receiving exercise-based CR compared to those
receiving standard care. The CR group demonstrated better scores on the SF-36 questionnaire
and significant reductions in blood pressure and cholesterol levels.
Quality of life
Improvements in HRQoL were evident across all domains of the SF-36 questionnaire, including
physical function, emotional well-being, and social functioning. These improvements were more
pronounced in the CR group compared to the standard care group.
Cardiovascular outcomes
The CR group showed significant reductions in systolic blood pressure and LDL cholesterol
levels compared to the standard care group. These changes indicate a reduced risk of future
cardiovascular events.
Exercise Capacity and Weight Management
Participants in the CR group demonstrated improvements in exercise capacity, measured by
increased walking distance during a six-minute walk test. Additionally, there was a significant
reduction in div mass index (BMI) among obese participants in the CR group.
Discussion
The findings of this review highlight the clinical effectiveness and cost-effectiveness of exercise-
based CR for patients with CAD, including those with obesity. The comprehensive approach of
CR addresses not only physical health but also lifestyle behaviors, leading to improved HRQoL
and reduced cardiovascular risk.
Implications for Practice
Healthcare providers should consider incorporating exercise-based CR into the management plan
for patients with CAD, especially those with obesity. This approach can lead to better patient
outcomes and reduced healthcare costs.
Future Research Directions
Future studies should focus on optimizing CR programs for obese patients with CAD, exploring
innovative strategies to enhance exercise capacity and weight management. Additionally, cost-
effectiveness analyses should be conducted to further support the integration of CR into
healthcare systems.
Conclusion
Exercise-based CR is a valuable intervention for managing CAD, particularly in patients with
obesity. By improving HRQoL and reducing cardiovascular risk factors, CR can significantly
enhance patient outcomes. Healthcare systems should prioritize the integration of CR into
standard care for CAD management.
