Primary percutaneous coronary intervention for unprotected left main disease in patients with acute ST-segment elevation myocardial infarction the AMIS (Acute Myocardial Infarction in Switzerland) plus registry experience.

OBJECTIVES: This study sought to assess outcomes in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI) for unprotected left main (LM) disease. BACKGROUND: Limited data are available on outcomes in patients with ST-segment elevation myocardial infarction undergoing LM PCI. METHODS: Of 9,075 patients with ST-segment elevation myocardial infarction enrolled in the AMIS (Acute Myocardial Infarction in Switzerland) Plus registry between 2005 and June 30, 2010, 6,666 underwent primary PCI. Of them, 348 (5.2%; mean age: 63.5 ± 12.6 years) underwent LM PCI, either isolated (n = 208) or concomitant to PCI for other vessel segments (n = 140). They were compared with 6,318 patients (94.8%; mean age: 61.9 ± 12.5 years) undergoing PCI of non-LM vessel segments only. RESULTS: The LM patients had higher rates of cardiogenic shock (12.2% vs. 3.5%; p < 0.001), cardiac arrest (10.6% vs. 6.3%; p < 0.01), in-hospital mortality (10.9% vs. 3.8%; p < 0.001), and major adverse cardiac and cerebrovascular events (12.4% vs. 5.0%; p < 0.001) than non-LM PCI. Rates of mortality and major adverse cardiac and cerebrovascular events were highest for concurrent LM and non-LM PCI (17.9% and 18.6%, respectively), intermediate for isolated LM PCI (6.3% and 8.3%, respectively), and lowest for non-LM PCI (3.8% and 5.0%, respectively). Rates of mortality and major adverse cardiac and cerebrovascular events for LM PCI were higher than for non-LM multivessel PCI (10.9% vs. 4.9%, p < 0.001, and 12.4% vs. 6.4%, p < 0.001, respectively). LM disease independently predicted in-hospital death (odds ratio: 2.36; 95% confidence interval: 1.34 to 4.17; p = 0.003). CONCLUSIONS: Emergent LM PCI in the context of acute myocardial infarction, even including 12% cardiogenic shock, appears to have a remarkably high (89%) in-hospital survival. Concurrent LM and non-LM PCI has worse outcomes than isolated LM PCI.

Psychodynamic psychotherapy in newly diagnosed cancer patients: a randomized controlled trial

Aims: (i) To describe the prevalence and profile of newly diagnosed cancer patients motivated for psychotherapy and (ii) To evaluate its effectiveness.Methods: Between 2006 and 2009, every new patient of the Oncology Service of the University Hospital Lausanne was informed of the opportunity to benefit from psychotherapeutic support. Patients were randomly assigned to an immediate or delayed (4 month waiting list) psychodynamicoriented psychotherapeutic intervention, formalized as short intervention (1-4 sessions) or brief psychotherapy (16 sessions). Patients with no interest were asked to participate in an observational group. Socio-demographic and medical data, anxiety and depression (HADS, SCL-90), alexithymia (TAS) and quality of life were evaluated for all groups at baseline and 1, 4, 8 and 12-months follow-up. Results: Of 1973 patients approached, 1024 were excluded, mainly because of organisational reasons (living too far away, interfering treatments, etc.), ageN75 years, life expectancyb1 year or language difficulties. One fourth (N=530) refused to participate and 229 patients accepted to be followed in the observational group. Patients interested in psychological support (N=190, 94 in immediate and 96 in delayed intervention) were younger, predominantly female and symptomatic (higher depression and anxiety scores); 56% engaged in 1-4 and 44% in 16 sessions.Conclusions: The naturalistic design of this study revealed relevant questions regarding (i) the design of such studies (untargeted intervention, choice of measurement, etc.), (ii) the type of interventions (pro-active approaches of men, those unable to speak the language or who can not leave home) and (iii) the profile of patients accepting support. A complete analysis will be presented at the congress.Keywords: Psychotherapy, psycho-oncology, cancer, methodology, interventions

Does Interviewer-Respondent Socio-Demographic Matching Increase Cooperation in Centralized CATI Household Panels?

Overall it seems that age and gender interviewer characteristics are relevant in achieving higher cooperation rates by telephone panel members. This appears to be the case especially for older male interviewers, who perform the best on gaining cooperation across different types of respondents. This holds if important interviewer covariates like experience are controlled for. There is no evidence that special sex age or sex matches yield a higher cooperation. It may be that not only the perceived authority of the institution that sponsors the survey plays a role when it comes to cooperation (Groves et al., 1992) but also of the interviewer who asks for this cooperation. Presumably older men have more authority to convince sample members to participate. A simple recommendation is to use as many older male interviewers as possible for the recruitment phase. It is likely that this strategy would also be successful in other western cultures than Switzerland.
