Coronary artery disease
In 2018, Rev Port Cardiol reported the 15-year results of the Portuguese Registry of Acute Coronary Syndromes (PorACS). This is a multi-center, continuous, and ongoing registry which has already involved more than 45,000 events, from 45 centers. It is one of the largest national registries in this field, which is only exceeded by the SWEDEHEART and the MINAP registries. This article provides very important information about the epidemiology and evolution of ACS treatment. First, it demonstrates that the clinical profile of ACS patients changed little over the years, and the proportion of ST-elevation myocardial infarction (STEMI) remained stable (45%). More importantly, over the years, there has been a major improvement in the overall quality of ACS care. For example, more than 85% of STEMI patients in Portugal now receive reperfusion therapy, which is mainly performed by primary PCI (only 5.2% underwent thrombolysis). This improvement in ACS care led to a remarkable reduction of in-hospital mortality, which decreased from 6.7% in 2002 to 2.5% in 2016. Therefore, the cardiovascular community must be acknowledged for this striking achievement. Nevertheless, the work is not finished, and this study also shows important gaps in ACS care that should be addressed. Unfortunately, time-to-reperfusion has not improved sufficiently, and there is an urgent need to improve both the “patient-delay” and “system-delay” times.
In another interesting article published in 2018, Pereira H. et al. evaluated the determinants of this “patient-delay” time in the Portuguese health system in 994 patients with suspected STEMI. Although most healthcare systems focus their performance measures in the evaluation of “door-to-balloon times”, it is important to understand and address the reasons for this “patient-delay time”, which means the time from symptom onset to the first medical contact. The investigators observed that patient-delay time was too long (about 120 minutes) and identified five predictors of increased patient-delay: 1) age > 75 years; 2) symptom onset between 0:00 and 8:00 a.m.; 3) attending a primary care unit before first medical contact; 4) not calling the national medical emergency number; and 5) self-transport to the emergency department. Therefore, this article provides important information to plan more effective patient-directed campaigns that can decrease patient-delay time and improve STEMI management and prognosis.
