Portugal has one of the lowest rates primary percutaneous coronary intervention (p-PCI) in Western Europe. This study assessed progress Portuguese p-PCI performance indicators year after joined Stent for Life (SFL) initiative. Two national surveys were carried out, each covering a period month: first when SFL 2011 (Moment Zero), and second later One). A total 397 consecutive patients with probable ST-segment elevation myocardial infarction enrolled (201 at Moment Zero 196 One) from 15...
The percentage of time during which the patients have INR within target values (i.e. Time in Therapeutic Range [TTR]) is a measure anticoagulation quality with Vitamin K Antagonists (VKA). To evaluate using TTR according to Rosendaal method, we performed an observational, retrospective study. We included all outpatients who attended cardiology clinic Portuguese hospital (2011–2013), whose was 2.0-3.0. 377 VKA-treated were evaluated. Of these, 72.4% had non-valvular atrial fibrillation....
The initial data of the International Study on Acute Coronary Syndromes - ST Elevation Myocardial Infarction COVID-19 showed in Europe a remarkable reduction primary percutaneous coronary intervention procedures and higher in-hospital mortality during phase pandemic as compared with prepandemic period. aim current study was to provide final results registry, subsequently extended outside larger inclusion period (up June 2020) longer follow-up 30 days).This is retrospective multicentre...
Primary percutaneous coronary intervention (PPCI) is the recommended treatment for patients with acute ST-segment elevation myocardial infarction (STEMI). Despite substantial evidence of its effectiveness, a 2007 study reported that only 40-45% European STEMI were treated PPCI, large variations in availability between countries. In 2008, Stent Life (SFL) initiative was launched by Association Percutaneous Cardiovascular Interventions and EuroPCR partnership Society Cardiology (ESC) Working...

To present the report on trends in percutaneous coronary activity data Portugal from last decade (from 2014 to 2023). Data were extracted Portuguese National Registry of Interventional Cardiology (RNCI) and numbers recent years compared complemented by information 2023 European Society Atlas (IC) survey, which was administered director every IC department. Linear regression analysis used assess over time. From 2023, there 160 101 interventions reported RNCI. The number annual PCI remained...
The Strategic Plan for Cardiovascular Health in Portugal is an initiative of the Portuguese Society Cardiology, developed together with European Cardiology to create a Plan, which has now been endorsed by Council Union. Building upon its conceptual framework, moved executing phase establishing Working Groups composed experts priority areas. Guided strategic pillars, these groups formulated action proposals encompassing health promotion, primary prevention and determinants, screening early...
Pulmonary endarterectomy should be considered in all patients with chronic thromboembolic pulmonary hypertension. 25% of maintain hypertension after endarterectomy, therapeutic and prognostic implications. We aimed to evaluate echocardiographic parameters at diagnosis as predictors for development residual Retrospective, observational, unicentric study confirmed who underwent between January 2010 October 2024. All transthoracic echocardiogram diagnosis. After had a right heart...
Background: Several scores have been developed to facilitate risk stratification and early discharge following primary angioplasty, particularly the Zwolle Risk Score (ZRS). However, validation in large-sized studies is still lacking. Therefore, aim of current study was validate use ZRS a contemporary global population, including patients who were treated during SARS-CoV-2 pandemic enrolled large intercontinental observational study. Methods: The ISACS-STEMI COVID-19 large-scale...
Abstract Introduction Infective endocarditis (IE) is a rare but seemingly increasing disease, particularly among older adults. Management of IE often varies by age group, with notably low rate cardiac surgery in octogenarians, attributed partially to heightened surgical risk advanced age. However, the underutilization linked unfavorable outcomes patients. Purpose To describe characteristics octogenarians and assess their prognosis. Methods We conducted retrospective, single-center analysis...
Abstract Introduction Heart Failure (HF) is the end stage of many cardiac disorders, with myocardial ischemia being leading cause in older patients. Traditionally, nonischemic etiologies HF have been more common younger individuals. However, recent studies suggest an increasing burden among populations, likely driven by a rise ischemic coupled increase Acute Coronary Syndromes (ACS). Despite this, evolution ACS to young individuals still poorly characterized. Purpose Determine incidence and...
Abstract Introduction Acute Coronary Syndrome (ACS) incidence in younger populations has been increasing worldwide. Several aspects remain unclear despite young individuals presenting distinct risk profiles compared to their older counterparts. A comprehensive understanding of the evolving characteristics and treatment options is crucial address burden ACS this population. However, data regarding long-term follow-up prognosis adults limited. Purpose Describe demographic, clinical...
