AI Article Synopsis
- The study aimed to evaluate the effectiveness of drug-coated balloons (DCB) in treating calcified coronary lesions, which are linked to worse outcomes after procedures.
- A total of 81 patients were analyzed, comparing results between those with calcified and non-calcified lesions after DCB treatment, finding no significant differences in late lumen loss or rates of restenosis.
- The results suggest that while calcified lesions could reduce DCB effectiveness, the overall clinical outcomes for patients with calcified lesions were similar to those without.
Article Abstract
Objectives: To investigate the efficacy of drug-coated balloon (DCB) for calcified coronary lesions.
Background: Calcified coronary lesions is associated with poor clinical outcomes after revascularization. Recently, DCB is emerging as an alternative strategy for de novo coronary lesions. However, reports describing the efficacy of DCB for calcified coronary lesions are limited.
Methods: A total of 81 patients (96 lesions) who electively underwent DCB treatment for de novo coronary lesions were enrolled: 46 patients (55 lesions) in the calcified group and 35 patients (41 lesions) in the non-calcified group. Angiographic follow-up data and clinical outcomes after the procedure were evaluated.
Results: The diameter of the DCB used was 2.5 ± 0.5 mm. No bail-out stenting was observed after DCB treatment. Rotational atherectomy was used in 82% of lesions in the calcified group. Follow-up angiography (median, 6.5 months after intervention) was performed for 59 patients (30 in the calcified group and 29 in the non-calcified group). Late lumen loss and rates of restenosis were comparable between the groups (0.03 mm in the calcified group vs -0.18 mm in the non-calcified group, P = 0.093 and 13.9% vs 3.03%, P = 0.095, respectively). The survival rates for target lesion revascularization free survival and major adverse cardiac events at 2 years were comparable between the groups (85.3% vs 93.4%, P = 0.64 and 81.4% vs 88.5%, P = 0.57, respectively).
Conclusion: Calcified coronary lesions might dilute the effect of DCB. However, clinical outcomes in the calcified group were similar to those in the non-calcified group.

Background: Atrial fibrillation (AF) persistence is associated with molecular remodeling that fuels electrical conduction abnormalities in atrial tissue. Previous research revealed DNA damage as a molecular driver of AF.
Objectives: This study sought to explore the diagnostic value of DNA damage in atrial tissue and blood samples as an indicator of the prevalence of electrical conduction abnormalities and stage of AF.

Background: Several randomized clinical trials have shown that the composite endpoint of death, stroke, and myocardial infarction (MI) is equivalent between carotid artery stenting and carotid endarterectomy. However, the risk of minor stroke has been consistently higher with carotid artery stenting.
Objectives: The authors sought to evaluate the safety and effectiveness of a novel carotid stent system comprised of a stent, an adjustable integrated embolic filter and a postdilation balloon, in patients at elevated risk for adverse events from carotid endarterectomy.

Aortic valve calcification results from degenerative processes associated with several pathologies. These processes are influenced by age, chronic inflammation, and high concentrations of phosphate ions in the plasma, which contribute to induce mineralization in the aortic valve and deterioration of cardiovascular health. Environmental factors, such as wood smoke that emits harmful and carcinogenic pollutants, carbon monoxide (CO), and nitrogen oxide (NO), as well as other reactive compounds may also be implicated.
