RESUMO
OBJECTIVES: Previous studies in other countries had shown lacunae in patients' and general publics' understanding of cardiovascular diseases. Such studies are lacking in Nepal. Hence the present study was carried out to: a) note the respondent's knowledge regarding myocardial infarction and hypertension and b) note the association, if any, of the knowledge with demographic and personal characteristics. MATERIALS AND METHODS: Respondents attending a cardiac camp organized in the Manipal Teaching hospital during September 2002 were interviewed by previously briefed seventh semester students using a structured questionnaire. Basic demographic information and knowledge about myocardial infarction and hypertension was collected. The median score was calculated. Differences in scores among different subgroups of respondents were noted using appropriate statistical tests (p<0.05). RESULTS: Sixty-six respondents were interviewed; 44 were male. The knowledge scores for heart attack and hypertension were 6 (maximum score 8) and 11 (maximum score 14) respectively. The scores were significantly lower among respondents with a monthly family income below 2000 rupees and was higher among respondents/family members suffering from cardiovascular disease. CONCLUSION: The respondents were aware of the basic facts regarding myocardial infarction and hypertension. However, lacunae in knowledge were noted. Further studies are required.
RESUMO
Visual Reaction Time (VRT) and Auditory Reaction Time (ART) were measured in right-handed and left-handed human volunteers, using an Electronic Response Timer Unit. The study demonstrated that a group of left-handed women reacted faster (P < 0.05) with their left hand to an auditory stimulus than their counterpart using their right hand. VRT did not show any significant change within, and between, the groups and was not influenced by sex or age. The observed differences in ART may be due to central phenomenon.
