ABSTRACT
The safety and efficacy of rotational atherectomy (RA) in patients with acute coronary syndrome (ACS) treated with different rotational speeds remain unclear. This was an observational retrospective registry study. Between February 2017 and January 2022, a total of 283 patients with ACS were treated with RA. The patients were divided into 2 groups: the low-speed group (130,000 to 150,000 rotations/min [rpm],182 cases) and the high-speed group (160,000 to 220,000 rpm, 101 cases) according to the maximum RA speed. The outcomes analyzed were procedural complications; incidence of heart failure, stent thrombosis, and cardiac death during hospitalization; and 30-day major cardiovascular and cerebrovascular events. Patients in the low-speed RA group had a higher incidence of vasospasm during RA (15.4% vs 6.9%, p = 0.040), whereas the incidence of slow blood flow was higher in the high-speed RA group (16.5% vs 27.7%, p = 0.031). There was no significant difference in other complications or in 30-day major cardiovascular and cerebrovascular events between the 2 groups. Moreover, logistic regression analysis identified rotational speed (160,000 to 220,000 rpm) as a predictor of slow flow during RA (odds ratio 1.900, 95% confidence interval 1.006 to 3.588, p = 0.048). For every 10,000-rpm increase in rotational speed, the risk of slow flow increased by 27% (odds ratio 1.273, 95% confidence interval 1.047 to 1.547, p = 0.015). In conclusion, patients with ACS treated with a lower RA speed (130,000 to 150,000 rpm) had a higher risk of vasospasm, whereas those treated with higher speeds (160,000 to 220,000 rpm) had a higher incidence of slow flow. High rotational speed (160,000 to 220,000 rpm) is an independent risk factor for slow flow during RA in patients with ACS.

BACKGROUND: To inquiry the predictive value of the age, creatinine, and ejection fraction (ACEF) score for cardiac mortality in patients diagnosed with heavily calcified coronary lesions at 1 year after percutaneous coronary intervention (PCI) with rotational atherectomy (RA). METHODS: 275 patients with heavily calcified coronary lesions undergoing PCI with RA in the Department of Cardiology of Anhui Provincial Hospital from January 2017 to December 2019 were consecutively recruited. The primary endpoint event was cardiac death at postoperative 1 year. The ROC curve was used to assess ACEF scoring system and predict cardiac mortality. RESULTS: In term of ACEF score upon admission, 275 patients were divided into low-to-intermediate risk group (n = 130) with ACEF score < 1.23 and high-risk group (n = 145) with ACEF score ≥ 1.23. The age, gender proportion and left ventricular ejection fraction (LVEF) have a significant difference between the low-to-intermediate risk group and the high-risk group (all P < 0.05). The area under ROC curve for ACEF scoring system to predict cardiac mortality at 1 year after PCI with RA was 0.756 and 0.715, respectively. CONCLUSIONS: ACEF value upon admission can predict the cardiac mortality at 1 year following PCI with RA in heavily calcified coronary lesions patients.
