- Hiperaldosteronismo primário: resultados do primeiro estudo multicêntrico português realizado pelo Grupo de Estudos de Tumores da Supra-RenalPublication . Fernandes, V; Silva, T; Martins, D; Gonçalves, D; Almeida, R; Monteiro, AM; Neves, C; Simões, H; Marques, P; Serra, F; Pereira, ML; Grupo de Estudos de Tumores da Supra-RenalIntroduction: Primary Aldosteronism (PA) is the most prevalent cause of secondary hypertension. Nevertheless, there is no portuguese multicenter study characterizing PA patients. Aims: To characterize the clinical presentation, diagnostic workup, treatment and follow-up of patients with confirmed PA. Methods: Retrospective multicenter study of PA patients followed in 9 portuguese hospitals. Results: Sixty-three cases were selected with a mean age of diagnosis of 52.1 ± 13.1 years, 9.9 years after the diagnosis of hypertension. At presentation, 37 cases (60.7%) had hypertension, 11 (22.9%) had resistant hypertension and 20 (32.8%) of patients had hipokalemia (mean 3.2 mmol/L). Baseline laboratory showed a mean serum aldosterone of 33.4ng/dL, plasmatic renin activity (PRA) of 0.2ng/mL/h with an aldosterone/PRA ratio of 97.1. Confirmatory testing was performed with saline infusion in 55 patients (positive in 84.4%) and captopril test in 14 (positive in 85.7%). Imaging showed adenomas in 55 cases, hyperplasia in 2 and bilateral cases in 8. Arterial venous sampling (AVS) was performed in 9 patients (14,5%) and was conclusive in 1. Iodocholesterol scintigraphy was done in 14 cases (22%) with unilateral fixation in 9 and no fixation in 4. Patients were treated with laparoscopic adrenalectomy in 28 cases (58.3%) and mineralocorticoid receptor antagonists in 20 cases (41.7%). The surgical treated group had less duration of hypertension (8 versus 14 years, p = 0.002), higher prevalence of anti-hypertensive drugs at presentation (100 versus 75% p = 0.009) and bigger tumour size (1.8 versus 1.5 cm, p = 0.022). During follow-up there was a trend towards a greater proportion of patients with no hypertension improvement in the medical treatment group (29.4% versus 7.4%, p = 0.089). Conclusion: This is the first Portuguese PA multicenter study. It suggests that PA remains an under- -diagnosed condition with a significant delay in diagnosis. Surgical treated patients had a more aggressive disease and showed a trend towards better hypertension control.
- Thrombus aspiration in patients with ST-elevation myocardial infarction: results of a national registry of interventional cardiologyPublication . Pereira, H; Caldeira, D; Teles, RC; Costa, M; da Silva, PC; da Gama Ribeiro, V; Brandão, V; Martins, D; Matias, F; Pereira-Machado, F; Baptista, J; Abreu, PF; Santos, R; Drummond, A; de Carvalho, HC; Calisto, J; Silva, JC; Pipa, JL; Marques, J; Sousa, P; Fernandes, R; Ferreira, RC; Ramos, S; Oliveira, EI; de Sousa Almeida, MBACKGROUND: We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in 'real-world' settings. METHODS: We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006-2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). RESULTS: We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54-1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35-0.98; 3500 patients). CONCLUSIONS: The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensity-score matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI..
- Trends in coronary angioplasty in Portugal from 2002 to 2013 according to the Portuguese National Registry of Interventional CardiologyPublication . Pereira, H; Campante Teles, R; Costa, M; Canas da Silva, P; da Gama Ribeiro, V; Brandão, V; Martins, D; Matias, F; Pereira-Machado, F; Baptista, J; Farto E Abreu, P; Santos, R; Drummond, A; Cyrne de Carvalho, H; Calisto, J; Silva, JC; Pipa, JL; Marques, J; Sousa, P; Fernandes, R; Cruz Ferreira, R; Ramos, S; Oliveira, E; Almeida, MINTRODUCTION AND OBJECTIVES: The aim of the present paper was to report trends in coronary angioplasty for the treatment of ST-elevation myocardial infarction (STEMI) in Portugal. METHODS: Prospective multicenter data from the Portuguese National Registry of Interventional Cardiology (RNCI) and official data from the Directorate-General for Health (DGS) were studied to analyze percutaneous coronary intervention (PCI) procedures for STEMI from 2002 to 2013. RESULTS: In 2013, 3524 primary percutaneous coronary intervention (p-PCI) procedures were performed (25% of all procedures), an increase of 315% in comparison to 2002 (16% of all interventions). Between 2002 and 2013 the rate increased from 106 to 338 p-PCIs per million population per year. Rescue angioplasty decreased from 70.7% in 2002 to 2% in 2013. During this period, the use of drug-eluting stents grew from 9.9% to 69.5%. After 2008, the use of aspiration thrombectomy increased, reaching 46.7% in 2013. Glycoprotein IIb-IIIa inhibitor use decreased from 73.2% in 2002 to 23.6% in the last year of the study. Use of a radial approach increased steadily from 8.3% in 2008 to 54.6% in 2013. CONCLUSION: During the reporting period there was a three-fold increase in primary angioplasty rates per million population. Rescue angioplasty has been overtaken by p-PCI as the predominant procedure since 2006. New trends in the treatment of STEMI were observed, notably the use of drug-eluting stents and radial access as the predominant approach.
