Long-term prognosis after recovery from myocardial infarction: a nine year follow-up of the Perth Coronary Register.

Patients registered by the 1971 Perth Coronary Register as having suffered a myocardial infarction were followed up for 9 years. The Register was a community-based study that used standard methods and criteria as part of a World Health Organization collaborative investigation. Of the 1078 patients studied, 77% survived the first 24 hr and 62% the first 28 days; 0.3% were lost to follow-up. For the 666 patients alive at 28 days, the crude 1, 5, and 9 year survival rates were 88%, 67%, and 52%, respectively. The relationship between 54 variables and the survival of patients alive 28 days after myocardial infarction was examined by life-table methods and the log rank test, and then by fitting a proportional hazards model to the data. The important prognostic factors were age, sex, past history of myocardial infarction, stroke, diabetes and hypertension, tachycardia at presentation, hypotension at presentation, and the occurrence of arrhythmias as short-term complications. The most appropriate mathematical description of the joint effects of the prognostic factors was a multiplicative model with no interaction.

The Effect of Role Model Influence on Adolescents’ Materialism and Marketplace Knowledge

The goal of the present research was to analyze the consumer socialization process of adolescents, utilizing social learning theory as a conceptual guide to understand how role models influence adolescents’ materialism and marketplace knowledge. A convenience sample of 175 teenagers between the ages of 15 and 18 were surveyed in a major metropolitan area. Direct role models included in this study were mothers, fathers and teachers. Vicarious role models included athletes and entertainers. Results at the .05 level of significance show that materialism and marketplace knowledge are associated with members of both direct and vicarious role model groups. Specifically for materialism, athletes and fathers were found to have the greatest impact. Teachers and athlete role models were found to have the greatest impact on adolescents’ marketplace knowledge. Implications from the empirical analysis of these proposed relationships are provided for marketing managers and practitioners.

Estimation of myocardial infarction mortality from routinely collected data in Western Australia

The accuracy of routinely collected mortality data for ischemic heart disease (IHD) as indicators of death from acute myocardial infarction (AMI) was assessed in ages 25-64 years, according to the WHO criteria defined in 1983. Cases were identified from computer records (linked for individuals) of all death certificates and hospital discharges in Western Australia between 1971 and 1982. Where the official cause was IHD about 90% of deaths fulfilled the WHO criteria for definite or possible AMI. Up to 10% of fatal cases of definite or possible AMI were coded to other causes in the official death statistics, however it appeared that variations in this figure with changes in coding practices could cause appreciable bias in the estimation of secular trends in IHD mortality. This problem could largely be overcome by reviewing fatal events where the death certificate was coded to one of a limited number of other ICD rubrics.

Attitude Toward Advertising: Race and Gender Differences

Attitude toward advertising has been an important area of research in the advertising literature for years. This paper extends the body of advertising and consumer behavior literature by examining the perceptual difference in attitude toward overall advertising between African American males, African American females, Caucasian males and Caucasian females. The study supports some previous research that found African Americans to have a more favorable attitude toward advertising. However, this work extends current advertising knowledge by showing that African Americans’ attitude toward advertising personal dimension are significantly different from Caucasian males but not Caucasian females.
