- Acute Coronary Syndrome and Stress: Is There a Relationship?Publication . Santos, H; Santos, M; Paula, S; Figueiredo, M; Almeida, I; Miranda, H; Chin, J; Sá, C; Neto, M; Almeida, S; Sousa, C; Almeida, LIntroduction: Acute coronary syndrome (ACS) is the result of a complex pathophysiological process with various dynamic factors. The 10-item Perceived Stress Scale (PSS-10) is a validated instrument for estimating stress levels in clinical practice and may be useful in the assessment of ACS. Methods: We carried out a single-center prospective study engaging patients hospitalized with ACS between March 20, 2019 and March 3, 2020. The PSS-10 was completed during the hospitalization period. The ACS group was compared to a control group (the general Portuguese population), and a subanalysis in the stress group were then performed. Results: A total of 171 patients with ACS were included, of whom 36.5% presented ST-elevation myocardial infarction (STEMI), 38.1% were female and the mean PSS score was 19.5±7.1. Females in the control group scored 16.6±6.3 on the PSS-10 and control males scored 13.4±6.5. The female population with ACS scored 22.8±9.8 on the PSS-10 (p<0.001). Similarly, ACS males scored a mean of 17.4±6.4 (p<0.001). Pathological stress levels were not a predictor of major adverse cardiovascular events or severity at admission. Conclusions: ACS patients had higher perceived stress levels compared to the control group. Perceived stress level was not associated with worse prognosis in ACS patients.
- A Systemic Review of Endocardial Left Ventricular PacingPublication . Santos, H; Santos, M; Almeida, I; Paula, S; Figueiredo, M; Portugal, G; Valente, B; Silva Cunha, P; Almeida, L; Oliveira, MMBackground: Endocardial left ventricular pacing is an alternative technique used in cardiac resynchronization therapy (CRT), when placement of a left ventricular lead is not possible via the coronary sinus or in non-responders to conventional CRT. Objectives: To review the evidence regarding the efficacy and safety of endocardial left ventricular pacing. Methods: Systematic research on Medline (PubMed), ClinicalTrials.gov and Embase with the terms "endocardial left ventricular pacing", "biventricular pacing" or "endocardial left pacing" was performed with the identification of 1038 results. Eleven studies with endocardial left ventricular pacing patients were included, independent of the technique being applied to naïve CRT patients or con non-responders to conventional CRT. The end-point of this analysis was the impact of endocardial left ventricular pacing techniques regarding New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF) and QRS width, and the occurrence of complications Mean differences (MD) and confidence interval (CI) was used as a measurement of treatment. Results: A total of 560 patients were included, with different techniques used (trans-atrial septal technique, trans-ventricular septal technique and transapical technique). Significant improvement was registered in NYHA class (MD 0.73, CI 0.48-0.98, p<0.00001, I2 = 87%), LVEF (MD -7.63, CI -9.93 - -5.33, p<0.00001, I2 = 69%) and QRS width (MD 29.25, CI 9.99-48.50, p<0.00001, I2 = 91%). Several complications were reported after the procedure, 11 pocket infections, 22 transient ischemic attacks, 18 ischemic strokes, 41 thromboembolic events, among other complications. The mortality rate during the follow-up was 20.54%. Conclusion: Left ventricular endocardial pacing is a feasible alternative to conventional CRT, with clinical, electrocardiographic and echocardiogrphic improvement. However, first data regarding this procedure was associated with significant complications rates.
- The Portuguese Severe Asthma Registry: Development, Features, and Data Sharing PoliciesPublication . Sá-Sousa, A; Fonseca, JA; Pereira, AM; Ferreira, A; Arrobas, A; Mendes, A; Drummond, M; Videira, W; Costa, T; Farinha, P; Soares, J; Rocha, P; Todo-Bom, A; Sokolova, A; Costa, A; Fernandes, B; Chaves Loureiro, C; Longo, C; Pardal, C; Costa, C; Cruz, C; Loureiro, CC; Lopes, C; Mesquita, D; Faria, E; Magalhães, E; Menezes, F; Todo-Bom, F; Carvalho, F; Regateiro, FS; Falcão, H; Fernandes, I; Gaspar-Marques, J; Viana, J; Ferreira, J; Silva, JM; Simão, L; Almeida, L; Fernandes, L; Ferreira, L; van Zeller, M; Quaresma, M; Castanho, M; André, N; Cortesão, N; Leiria-Pinto, P; Pinto, P; Rosa, P; Carreiro-Martins, P; Gerardo, R; Silva, R; Lucas, S; Almeida, T; Calvo, TThe Portuguese Severe Asthma Registry (Registo de Asma Grave Portugal, RAG) was developed by an open collaborative network of asthma specialists. RAG collects data from adults and pediatric severe asthma patients that despite treatment optimization and adequate management of comorbidities require step 4/5 treatment according to GINA recommendations. In this paper, we describe the development and implementation of RAG, its features, and data sharing policies. The contents and structure of RAG were defined in a multistep consensus process. A pilot version was pretested and iteratively improved. The selection of data elements for RAG considered other severe asthma registries, aiming at characterizing the patient's clinical status whilst avoiding overloading the standard workflow of the clinical appointment. Features of RAG include automatic assessment of eligibility, easy data input, and exportable data in natural language that can be pasted directly in patients' electronic health record and security features to enable data sharing (among researchers and with other international databases) without compromising patients' confidentiality. RAG is a national web-based disease registry of severe asthma patients, available at asmagrave.pt. It allows prospective clinical data collection, promotes standardized care and collaborative clinical research, and may contribute to inform evidence-based healthcare policies for severe asthma.
