BACKGROUND: Patients undergoing percutaneous coronary interventions (PCI) with rotational atherectomy (RA) have massively calcified coronary arteries and differ according to sex.
AIMS: To assess trends in sex-related percentage shares in following years, to compare demographic characteristics between men and women, and to identify factors associated with the risk of periprocedural complications and death.
METHODS: Based on the Polish National Registry of Percutaneous Coronary Interventions (ORPKI), we analyzed 751 113 patients treated with PCI between 2014 and 2020. We extracted 5 177 (0.7%) patients treated with RA, 3 552 of them (68.6%) being men. To determine risk factors of periprocedural complications and death, multivariable analysis was performed.
RESULTS: The proportion of PCIs involving RA increase between 2014 and 2020 (P < 0.001). Almost twice as many RA procedures pertain to men (68.55%), while the percentage share did not change in following years. Data are reported as mean (standard deviation). The female patients were older (75.2 [8.3] vs 70.5 [9.2] years; P < 0.001). When considering periprocedural complications, their overall rate (3.45% vs 2.31%; P = 0.01) and death rate (0.68% vs 0.17%; P = 0.006) were greater among women. Also, via multivariable analysis, female sex was found to be a risk factor of greater periprocedural mortality (P = 0.02) and overall complication rate (P = 0.007).
CONCLUSIONS: The majority of patients treated with RA are men and sex-related distribution was stable during the analyzed period of time. Female sex is a risk factor of greater periprocedural complications and mortality in patients treated with RA.
