RESUMO
The metabolic syndrome [Mets] consists of major clustering of cardiovascular disease [CVD] risk factors. This study determines the association of socioeconomic determinants and smoking behavior in a population-based sample of Iranians with Mets. This cross-sectional survey comprised 12600 randomly selected men and women aged >/= 19 years living in three counties in central part of Iran. They participated in the baseline survey of a community-based program for CVD prevention entitled" Isfahan Healthy Heart Program" in 2000-2001. Subjects with Mets were selected based on NCEP- ATPIII criteria. Demographic data, medical history, lifestyle, smoking habits, physical examination, blood pressure, obesity indices and serum lipids were determined. The mean age of subjects with Mets was significantly higher. The mean age of smokers in both groups was higher than non-smokers but with lower WC and WHR. Marital status, age and residency were not significantly different in smokers with Mets and non-smokers with Mets. Smoking was more common in the middle educational group in the income category of Quartile 1-3. Mets was significantly related to age, sex and education. Middle-aged and elderly smokers were at approximately 4-5 times higher risk among Mets subjects. Low education decreased the risk of Mets by 0.48; similarly in non-smokers, 6-12 years of education decreased the risk of Mets by 0.72. More educated persons had a better awareness and behavior related to their health and role of smoking. In the lower social strata of the Iranian population, more efforts are needed against smoking habits
RESUMO
In inferior MI, both circumflex [CX] and Right coronary artery [RCA] can be involved. Application of noninvasive paramedical evaluations in predicting of such events is considered to be worthwhile. Detection of coronary artery [RCA or CX] involvement in inferior myocardial infarction based on avR change. In 100 patients with inferior MI, 12-lead standard ECG was recorded in first 6 hours and ST-T change of avR evaluated. T-P segment was considered as isoelectric line. Data were analyzed using SPSS-12 and the sensitivity, specificity, positive and negative predictive values evaluated. RCA disease was seen in 72 patients and CX in 28. Isoelectric ST, ST depression and ST elevation in avR were seen in 61, 22 and 17 patients, respectively. Positive predictive value [PPV] of isoelectric ST for RCA disease was 78.7% compared with 21.3% for CX. PPV of ST elevation for RCA and CX diseases were 70.6% and 29.4%, respectively. PPP of ST depression for RCA disease was 54.5% compared to 45.5% for CX. Regarding the higher PPV of isoelectric ST, clinicians are suggested to employ this criterion in addition to other findings for RCA involvement prior to invasive procedure
