Chagas Cardiomyopathy as a Cause of Suspected Coronary Microvascular Disease

A clinical study compares patients with suspected coronary microvascular dysfunction (CMD) related to Chagas disease against patients with CMD from other causes. The dataset likely contains clinical, hemodynamic, angiographic, and scintigraphic characteristics for 101 stable patients with angina and normal epicardial coronary arteries, including 15 with suspected CMD-CE. The research was published by Felipe Campos in Arquivos Brasileiros de Cardiologia in 2020.

Use Cases

• Compare left ventricular ejection fraction between patient groups based on the statistical results mentioned.
• Analyze regional wall motion abnormalities in patients with suspected CMD-CE versus CMD-OE.
• Study the association between Chagas disease and diastolic dysfunction, indicated by elevated LV end-diastolic pressure.
• Investigate clinical and hemodynamic characteristics shared across different etiologies of suspected coronary microvascular disease.

Strengths

• Includes data from 101 patients meeting strict clinical criteria for suspected CMD.
• Provides specific statistical comparisons, such as LV ejection fraction (54.8 vs 61.1) and wall motion abnormality index (1.77 vs 1.18).
• Compares two distinct patient groups: 15 with suspected CMD-CE and 86 with suspected CMD-OE.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
