The incidence and prevention of systemic embolism in patients with chronic left ventricular aneurysm have been controversial. This retrospective study investigated the incidence of clinically evident embolic events and the effect of oral anticoagulation in patients with unequivocal angiographically defined left ventricular aneurysm. Between 1971 and 1979, 76 patients met the ventriculographic criteria and received initial medical management. The median interval from myocardial infarction to ventriculography was 11 months (range 1 month to 16 years) and subsequent median follow-up time was 5 years. Twenty patients receiving anticoagulant therapy were followed up for a total of 40 patient-years and 69 patients not on anticoagulant therapy were followed up for a total of 288 patient-years; 13 patients were included in both subsets. Twenty-eight patients died during follow-up and the 3 and 5 year survival rates were 75 and 61%, respectively. Only one patient not receiving anticoagulant therapy had a clinical embolic event, resulting in an incidence of 0.35 per 100 patient-years. Therefore, in the absence of other predisposing conditions, the extremely low incidence of systemic emboli in these patients with chronic (first documented at least 1 month after myocardial infarction) left ventricular aneurysm does not justify the use of long-term oral anticoagulant therapy.
To identify and explore cultural dynamics influencing the psychiatric care of immigrant Somalis in the USA, we reviewed demographic data from Minnesota Departments of Human Services, and interviewed health professionals, exploring community perceptions of medical/psychiatric needs, cultural characteristics, barriers to care, and potential solutions. An informal survey of 37 members of the Mayo Clinic Department of Psychiatry and Psychology, to determine caregiver perceptions of care of Somali patients, cited language barriers (74%), and cultural misperceptions (68%) as the most frequent obstacles. Difficulties working within the patriarchal family structure, limited community resources, poor compliance, and financial issues ranged between 18 and 8%. Additional barriers mentioned were problems working with interpreters from ;warring clan factions,' patients' fears of being labeled ;crazy,' difficulties viewing illness within an emotional framework, and the need to address mental health from a physical framework through a focus on somatic symptoms. Somalis rarely acknowledge psychiatric problems and common traditional treatments have become ineffective in the new context. Recommendations include alternative health care approaches utilizing family values, ;bargaining,' and educational approaches to acculturation.
The relative influences of revascularization status and baseline characteristics on long-term outcome were examined in 867 patients with multivessel coronary disease who had undergone successful coronary angioplasty. These patients represented 83% of a total of 1,039 patients in whom angioplasty had been attempted with an in-hospital mortality and infarction rate of 2.5% and 4.8%, respectively. Emergency coronary bypass surgery was needed in 4.9%. Of the 867 patients, 41% (group 1) were considered to have complete revascularization and 59% (group 2) to have incomplete revascularization. Univariate analysis revealed major differences between these two groups with patients in group 2 characterized by advanced age, more severe angina, a greater likelihood of previous coronary surgery and infarction, more extensive disease and poorer left ventricular function. Over a mean follow-up period of 26 months, the probability of event-free survival was significantly lower for group 2 only with respect to the need for coronary artery surgery (p = 0.004) and occurrence of severe angina (p = 0.04). The difference in mortality was of borderline significance (p = 0.051) and there were no significant differences between groups 1 and 2 in either the incidence of myocardial infarction or the need for repeat angioplasty. Multivariate analysis identified independent baseline predictors of late cardiac events that were then used to adjust the probabilities of event-free survival. This adjustment effectively removed any significant influence of completeness of revascularization on event-free survival for any of the above end points including the combination of death, myocardial infarction and need for coronary artery surgery. Therefore, late outcome in these patients is not significantly influenced by revascularization status but depends more on baseline patient characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
