Spanish cardiac catheterization and coronary intervention registry. 32nd official report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2022).

INTRODUCTION AND OBJECTIVES: This article presents the annual activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) for the year 2022. METHODS: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company in collaboration with the members of the board of the ACI-SEC. RESULTS: A total of 111 centers participated. The number of diagnostic studies increased by 4.8% compared with 2021, while that of percutaneous coronary interventions (PCI) remained stable. PCIs on the left main coronary artery increased by 22%. The radial approach continued to be preferred for PCI (94.9%). There was an upsurge in the use of drug-eluting balloons, as well as in intracoronary imaging techniques, which were used in 14.7% of PCIs. The use of pressure wires also increased (6.3% vs 2021) as did plaque modification techniques. Primary PCI continued to grow and was the most frequent treatment (97%) in ST-segment elevation myocardial infarction. Most noncoronary procedures maintained their upward trend, particularly percutaneous aortic valve implantation, atrial appendage closure, mitral/tricuspid edge-to-edge therapy, renal denervation, and percutaneous treatment of pulmonary arterial disease. CONCLUSIONS: The Spanish cardiac catheterization and coronary intervention registry for 2022 reveals a rise in the complexity of coronary disease, along with a notable growth in procedures for valvular and nonvalvular structural heart disease.

Prognostic value of an abnormal ankle-brachial index in patients receiving drug-eluting stents.

Advanced atherosclerotic disease increases the risk of stent thrombosis after drug-eluting stent (DES) implantation. We aimed to determine if an abnormal ankle-brachial index (ABI) value as a surrogate of atherosclerotic disease and vascular inflammation provides information on 1-year risk of cardiovascular events after DES implantation. A prospective cohort of 1,437 consecutive patients undergoing DES implantation from January through April 2008 in 26 Spanish hospitals was examined. ABI was calculated by Doppler in a standardized manner. Patients were followed to 12 months after the percutaneous coronary intervention to determine total and cardiovascular mortality, stroke, nonfatal acute coronary syndrome (ACS), and new revascularizations. Association of an abnormal ABI value (i.e., ≤ 0.9 or ≥ 1.4) with outcomes was assessed by conventional logistic regression and by propensity-score analysis. Patients with abnormal ABI values (n = 582, 40.5%) in general had higher global cardiovascular risk, the reason for DES implantation was more often ACS, and had a higher rate of complications during admission (heart failure or stroke or major hemorrhage 11.3% vs 5.3%, p <0.001). An abnormal ABI value was independently associated with 1-year total mortality (odds ratio 2.23, 95% confidence interval 1.13 to 4.4) and cardiovascular mortality (odds ratio 2.06, 95% confidence interval 1.04 to 4.22). No independent association was found between an abnormal ABI value and 1-year nonfatal ACS, stroke, and new revascularizations. In conclusion, although an abnormal ABI value was associated with fatal outcomes in patients receiving DESs, no association was found with nonfatal ACS and new revascularizations. A clear relation between abnormal ABI and surrogates of DES thrombosis could not be established.
