Background—: There are currently no guidelines advising long-term surveillance of patients following an acute pulmonary embolism (PE), because long-term outcome studies are rare. We investigated the long-term cardiovascular and all-cause mortality of a large patient cohort with confirmed PE in relation to baseline cardiovascular disease (CVD). Methods and Results—: Clinical details of all patients presenting with acute PE to a tertiary hospital were retrieved from medical records, and their survival tracked from a statewide death registry. There were 1023 (45% males) patients admitted with confirmed PE from 2000 to 2007. During a mean follow-up of 3.8±2.6 years, 363 patients died (35.5%), of whom only 31 (3.0%) died in-hospital during the index PE admission. The 3-month, 6-month, 1-year, 3-year, and 5-year cumulative mortality rates were 8.3%, 11.1%, 16.3%, 26.7%, and 31.6% respectively. Annual mortality did not improve over the 7-year period. The postdischarge mortality of 8.5%/patient-year was 2.5-fold that of an age- and sex-matched general population, being 12.6-fold in the youngest quintile (<55 years) and 1.9-fold in the oldest quintile (≥83 years). Patients with known CVD at baseline had 2.2-fold greater all-cause mortality than those without CVD, and this effect, although at a lower level of risk, remained significant after multivariate analysis. Of the 332 deaths occurring postdischarge, 40% were attributed to cardiovascular causes. Conclusions—: In a contemporary adult population, PE is associated with a substantially increased long-term mortality, of which nearly half is cardiovascular. Our study highlights the urgent need to develop long-term surveillance strategies in this population.

There is growing evidence for a relationship between fruit and vegetable consumption and all-cause mortality. Few studies, however, specifically explored consuming raw versus cooked vegetables in relation to health and mortality outcomes. The purpose of this study was to examine the relation of all-cause mortality with: a) fruit and vegetable consumption, either combined or separately; b) the consumption of raw versus cooked vegetables in a large cohort of Australian middle-aged and older adults. The sample included 150,969 adults aged 45 years and over from the 45 and Up Study, a prospective cohort study conducted in New South Wales, Australia. Self-reported baseline questionnaire data (2006–09) were linked to mortality data up to June 2014. Fruit and vegetable consumption was assessed by validated short questions. Crude and adjusted hazard ratios were calculated using Cox proportional hazard models. Covariates included socio-demographic characteristics, health-related and dietary variables. During a mean follow-up of 6.2 years, 6038 (4 %) participants died from all causes. In the fully adjusted models, increasing consumption of fruit and vegetables combined was associated with reductions in all-cause mortality, with the highest risk reduction seen up to 7 serves/day or more of fruit and vegetables (P for trend = 0.002, hazard ratio for highest versus lowest consumption quartile: 0.90; 95 % confidence interval: 0.84, 0.97). Separate consumption of fruit and vegetables, as well as consumption of raw or cooked vegetables, were associated with a reduced risk of all-cause mortality in the crude and minimally adjusted models (all P for trend <0.05). With the exception of raw vegetables, these associations remained significant in the fully adjusted models (all P for trend <0.05). Age and sex were significant effect modifiers of the association between fruit and vegetable consumption and all-cause mortality. Fruit and vegetable consumption were inversely related to all-cause mortality in this large Australian cohort. Further studies examining the effects of raw versus cooked vegetables are needed.

Patients with schizophrenia die on average 25 years earlier than the general population, and this gap appears to be increasing. Most of the excess mortality is due to premature cardiovascular deaths rather than suicide. Many psychotropic agents are orexigenic and can increase weight and promote dyslipidaemia. Traditional cardiac risk factors are undertreated among patients with schizophrenia, and they are less likely to receive cardiac revascularisation than those without a mental illness. Clozapine is an atypical antipsychotic medication effective for treatment of refractory schizophrenia, but is associated with the risk of myocarditis and cardiomyopathy. Established protocols in Australia screen for myocarditis for patients who are initiating clozapine therapy and for long term monitoring for cardiomyopathy with echocardiography. Coordinated care between tertiary providers, general practitioners and primary health care professionals should monitor the physical health of people with psychosis or schizophrenia at least annually and treatment should be offered accordingly.
