    Aims  The third Universal Definition of Myocardial Infarction (MI) Task Force classified MIs into five types: Type 1, spontaneous; Type 2, related to oxygen supply/demand imbalance; Type 3, fatal without ascertainment of cardiac biomarkers; Type 4, related to percutaneous coronary intervention; and Type 5, related to coronary artery bypass surgery. Low-density lipoprotein cholesterol (LDL-C) reduction with statins and proprotein convertase subtilisin–kexin Type 9 (PCSK9) inhibitors reduces risk of MI, but less is known about effects on types of MI. ODYSSEY OUTCOMES compared the PCSK9 inhibitor alirocumab with placebo in 18 924 patients with recent acute coronary syndrome (ACS) and elevated LDL-C (≥1.8 mmol/L) despite intensive statin therapy. In a pre-specified analysis, we assessed the effects of alirocumab on types of MI. Methods and results  Median follow-up was 2.8 years. Myocardial infarction types were prospectively adjudicated and classified. Of 1860 total MIs, 1223 (65.8%) were adjudicated as Type 1, 386 (20.8%) as Type 2, and 244 (13.1%) as Type 4. Few events were Type 3 (n = 2) or Type 5 (n = 5). Alirocumab reduced first MIs [hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.77–0.95; P = 0.003], with reductions in both Type 1 (HR 0.87, 95% CI 0.77–0.99; P = 0.032) and Type 2 (0.77, 0.61–0.97; P = 0.025), but not Type 4 MI. Conclusion  After ACS, alirocumab added to intensive statin therapy favourably impacted on Type 1 and 2 MIs. The data indicate for the first time that a lipid-lowering therapy can attenuate the risk of Type 2 MI. Low-density lipoprotein cholesterol reduction below levels achievable with statins is an effective preventive strategy for both MI types.For complete list of authors see http://dx.doi.org/10.1093/eurheartj/ehz299</p

    Background: Previous trials of PCSK9 (proprotein convertase subtilisin-kexin type 9) inhibitors demonstrated reductions in major adverse cardiovascular events, but not death. We assessed the effects of alirocumab on death after index acute coronary syndrome. Methods: ODYSSEY OUTCOMES (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) was a double-blind, randomized comparison of alirocumab or placebo in 18 924 patients who had an ACS 1 to 12 months previously and elevated atherogenic lipoproteins despite intensive statin therapy. Alirocumab dose was blindly titrated to target achieved low-density lipoprotein cholesterol (LDL-C) between 25 and 50 mg/dL. We examined the effects of treatment on all-cause death and its components, cardiovascular and noncardiovascular death, with log-rank testing. Joint semiparametric models tested associations between nonfatal cardiovascular events and cardiovascular or noncardiovascular death. Results: Median follow-up was 2.8 years. Death occurred in 334 (3.5%) and 392 (4.1%) patients, respectively, in the alirocumab and placebo groups (hazard ratio [HR], 0.85; 95% CI, 0.73 to 0.98; P=0.03, nominal P value). This resulted from nonsignificantly fewer cardiovascular (240 [2.5%] vs 271 [2.9%]; HR, 0.88; 95% CI, 0.74 to 1.05; P=0.15) and noncardiovascular (94 [1.0%] vs 121 [1.3%]; HR, 0.77; 95% CI, 0.59 to 1.01; P=0.06) deaths with alirocumab. In a prespecified analysis of 8242 patients eligible for ≥3 years follow-up, alirocumab reduced death (HR, 0.78; 95% CI, 0.65 to 0.94; P=0.01). Patients with nonfatal cardiovascular events were at increased risk for cardiovascular and noncardiovascular deaths (P<0.0001 for the associations). Alirocumab reduced total nonfatal cardiovascular events (P<0.001) and thereby may have attenuated the number of cardiovascular and noncardiovascular deaths. A post hoc analysis found that, compared to patients with lower LDL-C, patients with baseline LDL-C ≥100 mg/dL (2.59 mmol/L) had a greater absolute risk of death and a larger mortality benefit from alirocumab (HR, 0.71; 95% CI, 0.56 to 0.90; Pinteraction=0.007). In the alirocumab group, all-cause death declined wit h achieved LDL-C at 4 months of treatment, to a level of approximately 30 mg/dL (adjusted P=0.017 for linear trend). Conclusions: Alirocumab added to intensive statin therapy has the potential to reduce death after acute coronary syndrome, particularly if treatment is maintained for ≥3 years, if baseline LDL-C is ≥100 mg/dL, or if achieved LDL-C is low.

    Trata-se de estudo de intenção epistemológica acerca da teoria do alcance de metas de King e suas contribuições para o conhecimento e prática de enfermeiros que atuam no Programa "Saúde da Família" (PSF), Brasil. Aplicou-se o componente Análise, do Método de Análise de Teorias de Meleis na reflexão crítica sobre a teoria, e tomou-se de leituras e reflexões quanto às diretrizes e propostas do PSF para perceber a interface entre os dois paradigmas em estudo. Identificou-se haver coerência entre as duas propostas de abordagem, o que leva as autoras a recomendarem a adoção dos ensinamentos de King na prática do PSF, no sentido da enfermagem obter maiores e melhores resultados de suas ações.<br>Se trata de un estudio de intención epistemológica respecto a la teoría del alcance de metas de King y sus contribuciones al conocimiento y la práctica de los enfermeros que actúan en el Programa "Salud de la Familia" (PSF), Brasil.

The analysis component, based on the Meleis' Method of Theory Analysis concerning critical thought on the theory, was applied as well as reading and thoughts on FHP guidelines and proposals in order to verify the interface between the two paradigms in the study. The outcome of the study proves that the two approaching proposals are coherent. Such coherence drives authors to recommend the adoption of King's teachings concerning FHP practice for nursing to obtain greater and better results in its actions

    O estudo propõe identificar os estressores vivenciados pelos familiares no processo de doação de órgãos, evidenciar o momento mais desgastante do processo e verificar a associação de variáveis com a experiência vivenciada pelos familiares. A amostra constituiu-se de 16 familiares que realizaram a doação por meio de uma Organização de Procura de Órgãos, na cidade de São Paulo, em 2007. Utilizou-se um instrumento estruturado com questões versando sobre a experiência e avaliação dos familiares no processo de doação. Os principais estressores foram: insatisfação com o atendimento (31,25%); receber a notícia da morte encefálica de forma intranquila (62,50%); e a demora para a liberação do corpo (62,50%), sendo este o momento mais desgastante do processo. Pelo coeficiente phi, verificou-se associação moderada entre as variáveis de interesse com a experiência da família. Conclui-se que o processo de doação é estressante para a família e que a assistência de enfermagem torna-se necessária em cada etapa da doação, oferecendo suporte para diminuir o sofrimento dos familiares.<br>El estudio propone identificar los estresores experimentados por los familiares en el proceso de donación de órganos, evidenciar el momento más desgastante y verificar la asociación de variables con la experiencia afrontada por los familiares. La muestra se constituyó de 16 familiares que realizaron la donación en una Organización de Búsqueda de Órganos de la ciudad de São Paulo, en 2007. Se utilizó un instrumento estructurado con preguntas referidas a la experiencia y evaluación de los familiares en el proceso de donación. Lo principales estresores fueron: la insatisfacción con la atención (31,25%); recibir la noticia de muerte encefálica en forma impropia (62,50%) y la demora para la liberación del cuerpo (62,50%), siendo éste el momento más desgastante. Por el coeficiente Phi, se verificó asociación moderada entre las variables de interés con la experiencia de la familia. Concluyendo, el proceso de donación de órganos es estresante para la familia, y la atención de enfermería se vuelve necesaria en cada etapa de la donación, brindando apoyo para disminuir el sufrimiento de los familiares.<br>The purpose of the present study is to identify the stressors experienced by family members during the process of organ donation, evince the most distressful moment of the process and verify the association of variable with the family members' experience. The sample consisted of 16 family members that were making the donation through a Organ Search Organization, in São Paulo, in 2007. A structured instrument was used, containing question addressing the family members' experience and their evaluation of the donation process. The main stressors reported were: dissatisfaction with the service (31.25%); receiving a harsh notification about the individual's brain death (62.50%); and the wait to release the body (62.50%), which was considered the most distressful moment of the process. Using the phi coefficient, it was found that there was a moderate association between the variables of interest with the family's experience. In conclusion, the donation process is stressful on the family and nursing care is necessary in each stage of the process to offer support and reduce the distress on the family members
