Retrospective cohort analysis of Spanish national trends of coronary artery bypass grafting and percutaneous coronary intervention from 1998 to 2017

Abstract

IntroductionSpain is one of the countries with the lowest rates of revascularisation and highest ratio of percutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG).ObjectivesTo investigate the changes and trends in the two revascularisation procedures between 1998 and 2017 in Spain.DesignRetrospective cohort study. Analysis of in-hospital outcomes.SettingMinimum basic data set from the Spanish National Department of Health: mandatory database collecting information of patients who are attended in the Spanish public National Health System.Participants603 976 patients who underwent isolated CABG or PCI in the Spanish National Health System. The study period was divided in four 5-year intervals. Patients with acute myocardial infarction on admission were excluded.Primary and secondary outcomesWe investigated the volume of procedures nationwide, the changes of the risk profile of patients and in-hospital mortality of both techniques.ResultsWe observed a 2.2-fold increase in the rate of any type of myocardial revascularisation per million inhabitants-year: 357 (1998) to 776 (2017). 93 682 (15.5%) had a coronary surgery. PCI to CABG ratio rose from 2.2 (1998–2002) to 8.1 (2013–2017). Charlson’s index increased by 0.8 for CABG and 1 for PCI. The median annual volume of PCI/hospital augmented from 136 to 232, while the volume of CABG was reduced from 137 to 74. In the two decades, we detected a significant reduction of CABG in-hospital mortality (6.5% vs 2.6%, p<0.001) and a small increase in PCI (1.2% vs 1.5%, p<0.001). Risk adjusted mortality rate was reduced for both CABG (1.51 vs 0.48, p<0.001), and PCI (1.42 vs 1.05, p<0.001).ConclusionWe detected a significant increase in the volume of revascularisations (particularly PCI) in Spain. Risk-adjusted in-hospital mortality was significantly reduced.

Aortocoronary Bypass Surgery in Patients with Recurrent Post-Coronary Stenting Angina

“…Обширное внедрение в клинику чрескожных коронарных вмешательств (ЧКВ) привело к снижению количества операций аортокоронарного шунтирования (АКШ) в среднем почти на треть [1,2]. Поменялся и профиль пациентов, которых направляют на АКШ.…”

The Effect of Coronavirus Outbreak on the Utilization of Coronary Revascularization Procedures: An Interrupted Time Series Analysis

“…Percutaneous coronary intervention (PCI) and coronary artery bypass grafts (CABG) are the two main techniques used for revascularization procedures for patients with chronic coronary artery disease. Both procedures have been showing different trends in their utilization in Spain in recent years: on the one hand, in the last two decades, PCI showed a three times increase, whereas, on the other hand, the proportions of CABG reduced by 27% [ 6 ].…”

Variablity of Mechanical or Tissue Valve Implantation in Patients Undergoing Surgical Aortic Valve Replacement in Spain: National Retrospective Analysis from 2007 to 2018

“…This database contains individualized and anonymized data, coded according to International Classification of Diseases (ICD)-9 and -10. Although the use of non-dedicated administrative data sources, such as this, for the analysis of indicators in cardiac surgery is controversial [ 17 ], different studies based on MBDS have validated its utility in analyzing the results of clinical processes [ 18 , 19 , 20 , 21 ] in Spain.…”
