Hypothesis
This study aimed to determine the practical coronary angiographic predictors for revascularization in patients with intermediate lesions who underwent repeated angiograms.
Conclusion
Angiographic haziness and % diameter stenosis greater than 60% were identified as independent predictors for target lesion revascularization in patients with intermediate coronary lesions.
Supporting Evidence
- The TLR (+) group had a higher percentage of diameter stenoses compared to the TLR (−) group.
- The prevalence of branches and haziness was higher in the TLR (+) group.
- Angiographic haziness was found to be a significant predictor for TLR.
- Patients with % diameter stenosis ≥ 60% had a higher TLR rate.
Takeaway
Doctors can look for certain signs in heart scans to help decide if patients with moderate blockages in their arteries need more treatment.
Methodology
This was a retrospective single-center study analyzing medical records of patients who underwent repeated coronary angiograms.
Limitations
The study is retrospective, did not use FFR or IVUS, and had a relatively small sample size.
Participant Demographics
The study included 437 patients with intermediate lesions, with a mean follow-up of 34.2 months.
Statistical Information
P-Value
p = 0.006 for diameter stenosis, p < 0.001 for haziness
Confidence Interval
95% confidence interval = 1.240–3.644 for haziness, 95% confidence interval = 1.013–1.037 for % diameter stenosis
Statistical Significance
p<0.05
