Clinical Scorecard: Mortality Differences in Acute Myocardial Infarction and Heart Failure Patients: A Systematic Review and Meta-Analysis of Rural versus Urban Populations

At a Glance

Key Highlights

• Rural patients with AMI and HF have higher all-cause mortality compared to urban patients (AMI OR 1.18; HF OR 1.11).
• Rural patients have higher rates of comorbidities, physical inactivity, poverty, and lower health insurance coverage.
• Rural healthcare access is limited by hospital closures, reduced availability of critical interventions, and challenges in post-acute care.

Guideline-Based Recommendations

Diagnosis

• Ensure timely diagnosis of AMI and HF in rural patients despite geographic and resource limitations.

Management

• Improve access to guideline-directed medical therapies and critical interventions such as cardiac catheterization and percutaneous coronary intervention in rural areas.
• Address socioeconomic and comorbidity factors influencing treatment adherence and outcomes.

Monitoring & Follow-up

• Implement follow-up systems to monitor post-discharge mortality and rehospitalization in rural patients.
• Track disparities in treatment utilization and outcomes between rural and urban populations.

Risks

• Recognize increased mortality risk in rural patients due to delayed or limited access to acute and post-acute cardiac care.
• Consider higher prevalence of comorbidities and socioeconomic barriers impacting rural patient outcomes.

Patient & Prescribing Data

Rural and urban patients post-AMI

Urban patients have higher usage rates of antiplatelets, beta-blockers, ACE inhibitors/ARBs, and statins compared to rural patients, though some studies show mixed results regarding medication use disparities.

Clinical Best Practices

• Prioritize improving healthcare infrastructure and access in rural areas to reduce mortality disparities.
• Enhance delivery of guideline-directed medical therapies and critical interventions for rural patients.
• Address socioeconomic determinants and comorbidities through integrated care approaches.
• Develop targeted policies to prevent rural hospital closures and expand post-acute care services.
• Implement community-based programs to increase physical activity and reduce cardiovascular risk factors in rural populations.
