Implication

May warrant psychological screening in elderly ischemic heart disease; hypothesis-generating for prospective validation of cluster-based interventions.

Key Points

The aim is to explore symptom clusters in elderly patients with ischemic coronary heart disease and their impact on health outcomes.
Elderly (age ≥ 65) unpartnered patients (N = 247) with ischemic coronary heart disease were enrolled from five medical centers.
Interviews assessed symptoms, medical history, physical/mental health, mood states, and quality of life.
Patients were clustered using squared Euclidean distances and weighted average linkage.
Three clusters were identified: Classic Acute Coronary Syndrome (22%), Weary (29%), and Diffuse Symptoms (49%).
The Weary group showed higher rates of heart failure, significant psychological distress, and lower quality of life compared to other clusters.

Population

247 elderly (≥65 years), unpartnered patients admitted with ischemic coronary heart disease across five university medical centers.

Outcome

Symptom clusters based on presenting symptoms in the week before hospitalization and their variation in general physical and mental health, mood states, and quality of life.patient reported

Elderly patients presenting with ischemic heart disease can be grouped into three distinct symptom clusters, with the 'Weary' phenotype experiencing the highest psychological distress and lowest quality of life.

Limitations

Further research is needed to clarify the relationships among identified symptoms, psychological distress, and health outcomes

Lindgren et al. (2008) conducted a cross-sectional in Ischemic coronary heart disease (n=247). Prehospital symptom clusters was evaluated on Symptom clusters and their association with psychological distress and quality of life. Cluster analysis of prehospital symptoms identified three groups, with the Weary cluster (29%) exhibiting significantly more psychological distress and lower quality of life than other subgroups.
