[The SYNTAX Revascularization Index and major cardiovascular events in patients with multivessel coronary artery disease in the Instituto Nacional de Cardiología Ignacio Chávez - Mexico].

Objective: To evaluate the degree of incomplete revascularization in patients with multiarterial coronary artery disease who underwent percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) using the Syntax revascularization index (SRI) and its relationship to major cardiovascular events during follow-up.

Materials And Methods: Observational, retrospective study with 4-year follow-up of patients with multiarterial coronary artery disease who underwent surgical or percutaneous coronary revascularization, in whom the baseline Syntax score (SSb) and the residual Syntax score (SSr) were calculated. The Syntax Revascularization Index (SRI) was determined with the following formula: SRI = (1- [SSr/SSb]) x 100, and major cardiovascular events at 4-year follow-up were compared.

[Should i treat a high risk chronic coronary syndrome invasively from the beginning? Yes, in most cases].

Chronic coronary syndrome (SCC) previously known as stable coronary disease, is the main cause of mortality in the world, and it is one of the most important in Peru. This pathology has a dynamic nature that results in different clinical scenarios that can be modified through various therapeutic options, one of which is coronary interventional treatment, mainly in patients with high ischemic risk defined as ischemia greater than 10% of the entire left ventricular mass. For this reason, we have analyzed the most relevant and current information available, concluding that the treatment of high ischemic risk´s chronic coronary syndrome, after an individual evaluation, would correspond to an invasive management from the beginning, although it would not impact on mortality or cardiovascular events, it would contribute to improve quality of life; also we should consider the incomplete availability of all the therapeutic options for the symptomatic management of this disease, the limited access to the management of acute cardiovascular events in our country, as well as the risk of adverse effects and drug interactions.
