Coronary Tortuosity and Myocardial Ischemia Association in 57 Patients

Between January 2015 and December 2017, a retrospective study enrolled 57 patients with angina and nonobstructive coronary artery disease. The dataset likely contains angiographic and perfusion imaging variables used to assess the association between coronary tortuosity and myocardial ischemia. The research was authored by André Estrada and is available via the paperswithcode platform.

Use Cases

• Predicting myocardial ischemia risk based on angiographic tortuosity features mentioned in the description
• Analyzing the relationship between coronary bend angles and perfusion deficits in specific vascular territories
• Developing classification models to identify patients with ischemia from nonobstructive coronary artery disease using clinical and imaging variables

Strengths

• Study includes 57 patient records with a mean age of 58.3 years
• Coronary tortuosity was observed in 16 patients (28%) and in 24 of 171 arteries, providing specific prevalence data
• Statistical analysis was performed with significance determined at the 5% level

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• Data may reflect temporal and selection bias inherent to the single-center retrospective study design from 2015-2017
