Creation and assessment of a long-term mortality forecasting model for survivors of acute coronary syndrome: an analysis of a primarily male, lower-risk group capable of undergoing cardiopulmonary exercise testing
Clinical Scorecard: Long-term Mortality Forecasting Model for Survivors of Acute Coronary Syndrome Incorporating Cardiopulmonary Exercise Testing
At a Glance
Category
Detail
Condition
Acute Coronary Syndrome (ACS)
Key Mechanisms
Sudden reduction in cardiac blood supply causing myocardial damage; cardiopulmonary function assessed via exercise testing provides prognostic value
Target Population
Primarily male ACS survivors aged 18-80 capable of undergoing cardiopulmonary exercise testing
Care Setting
Cardiac rehabilitation and outpatient follow-up in tertiary hospital setting
Key Highlights
Developed a novel long-term (up to 16 years) mortality prediction model for ACS survivors incorporating dynamic cardiopulmonary exercise testing (CPET) indicators.
Study cohort consisted of 299 ACS patients from Shanghai Tongji Hospital, selected based on ability to safely complete CPET and excluding unstable or severe comorbid conditions.
Existing models mostly use static indicators and short follow-up; this model integrates CPET data to better reflect overall cardiopulmonary health and improve long-term prognostic accuracy.
Guideline-Based Recommendations
Diagnosis
Confirm ACS diagnosis according to 2023 ESC guidelines before risk stratification.
Use comprehensive clinical and CPET data to assess cardiopulmonary function.
Management
Incorporate CPET parameters into long-term risk stratification to guide individualized treatment and rehabilitation plans.
Monitor and optimize modifiable risk factors identified through CPET and clinical evaluation.
Monitoring & Follow-up
Conduct regular follow-up including CPET assessments to monitor cardiopulmonary status and adjust management accordingly.
Use long-term mortality risk predictions to inform frequency and intensity of surveillance.
Risks
Exclude patients with unstable angina, recent myocardial infarction (<2 days), uncontrolled arrhythmias, severe valvular disease, or other contraindications from CPET due to safety concerns.
Recognize that lower event rates in lower-risk populations may reduce predictive model power.
Patient & Prescribing Data
ACS survivors aged 18-80 years, primarily male, capable of completing CPET without contraindications.
CPET-derived cardiopulmonary parameters provide additional prognostic information beyond traditional risk factors, potentially guiding tailored interventions to improve long-term survival.
Clinical Best Practices
Select ACS patients carefully for CPET ensuring safety and feasibility.
Use dynamic CPET indicators alongside traditional clinical variables for comprehensive risk stratification.
Apply long-term follow-up data (up to 16 years) to validate and refine mortality risk models.
Adhere to ethical standards including anonymization and protocol registration in prognostic studies.

Patients with lower nonischemic resting full-cycle ratio values had more repeat revascularizations despite similar 2-year major cardiovascular event rates.
