Insights
Severe diffuse coronary artery disease not amenable to revascularization affects 12.2% of patients, predominantly older men with comorbidities. Despite challenges, contemporary prognosis is improving for this high-risk group.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Clinical Epidemiology
Background:
- Severe diffuse coronary artery disease (CAD) unsuitable for revascularization is poorly understood, characterized by high morbidity, mortality, and reduced quality of life.
- Limited contemporary research exists on the epidemiology, clinical presentation, and prognosis of this specific CAD subset.
Purpose of the Study:
- To investigate the epidemiological, clinical, and prognostic aspects of three-vessel coronary artery disease not amenable to revascularization.
- To address the knowledge gaps concerning this high-risk patient population.
Main Methods:
- Retrospective observational cohort study.
- Data collected from a National Medical Center.
Main Results:
- Prevalence of three-vessel CAD not amenable to revascularization was 12.2%.
- Patients were predominantly male (66%), over 65 years, with significant comorbidities.
- Cardiovascular mortality was 9.4%; myocardial infarction occurred in 10.4%. Key mortality predictors included chronic kidney disease, age >70, and mitral valve insufficiency.
Conclusions:
- Three-vessel coronary artery disease not amenable to revascularization remains a frequent clinical entity.
- This patient group exhibits a high-risk clinical and anatomical profile.
- Despite knowledge gaps, contemporary prognosis shows improvement for this condition.
Background:
Severe diffuse coronary artery disease with anatomy that is not amenable to revascularization represents a poorly studied entity, with a poorly defined prognosis and prevalence, associated with high morbidity and mortality, poor quality of life and high hospitalization rates.
Objective:
Due to the limited evidence in this clinical field and the absence of contemporary studies, we decided to explore this line of research, determining epidemiological, clinical and prognostic aspects.
Material And Methods:
Analytical, retrospective observational cohort study, carried out in a National Medical Center.
Results:
The prevalence of three-vessel coronary artery disease not susceptible to revascularization was 12.2%, the majority were men (66%), over 65 years of age, with a high burden of comorbidities: pharmacological management consisted of beta blockers (91.5 %), antiplatelet aggregation (95.3%) and statins (95.3%): cardiovascular mortality was 9.4%, with myocardial infarction occurring in 10.4%: the predictor variables of mortality were chronic kidney disease, age over 70 years, insufficiency mitral valve.
Conclusion:
Coronary artery disease of three vessels not susceptible to revascularization continues to be a frequent entity, with a high-risk clinical and anatomical profile, with a better contemporary prognosis despite the multiple gaps in knowledge that limit its understanding and treatment.
