RESUMEN
Risk assessment for fast growing burden of cardiovascular diseases is very important and difficult. As a response to this challenge, in particular, genetic risk factors which potentially modify risk, we conducted a survey of primary data registry of Shiraz Heart Study on integration and application of family history data in prevention of cardiovascular disorders. This study is a longitudinal cohort project to be extended from subpopulations of different job groups to the community. Parental family history of MI, diabetes mellitus [DM], hyperlipidemia [HPL], hypertension [HTN] was reported more frequently among females than males. Histories of MI, DM, HPL, and HTN in both parents were respectively positive in 2.6%, 2%, 4.6%, and 7.9% of the participants. Odd ratios [OR] for risk of MI from family history of MI were 2.7; risk of DM from family history of DM 4.5; risk of HPL from family history of HPL 2.04; and risk of HTN from family history HTN 4.7. Also, family history of MI modifies risk of HPL [OR=1.7, P<0.0001]; and family history of DM modifies risk of HPL [OR=2.04, P<0.0001]. Our primary result shows potent application of family history data in risk assessment of cardiovascular outcome. In particular, HTN appears as a silent and leading risk modifier. In regard to the course of continuing Shiraz Heart Study integration of family history of risk factors crucial in public health we suggest to adopt a network of electronic health records from the [Health House] to the [Heart House]
RESUMEN
Coronary Heart Disease is commonly associated with obesity, raised serum lipid levels and changes in blood pressure. The present study was designed to assess the effect of low fat- high calcium, and low fat- high fiber diets on weight reduction, lipid profile and blood pressure. The study sample consisted of 136 referred patients adult, obese men aged 53-64 years. Samples randomly were subdivided in two groups. Group 1 was advised 1600 calories, 20% fat, 1600 mg calcium rich diet and group 2 followed similar diet as for group 1 except a total daily intake of 55g fiber and 900 mg calcium per day for 12 weeks. Blood samples were collected and assayed for total cholesterol, LDL-cholesterol, HDL-cholesterol and TG. Anthropometric assessments included measurement of weight, height, and waist circumferences followed by calculating Body mass index. Systolic and diastolic blood pressures were measured by using sphygmomanometer. Statistical analysis was performed with parametric and non-parametric methods as appropriate. Data analysis revealed a significant decrease in total cholesterol, LDL-cholesterol, and TG in two groups, without any significant changes in HDL-cholesterol. Weight and blood pressure decreased in two groups, but the rate of reduction in blood pressure, weight and waist circumference were more significant in group 1 compared to group 2. An increase in dietary calcium intake, together with a Low calorie, low-fat diet can increase lipolysis in fat tissues, make greater weight loss, ameliorate blood pressure, improve lipid levels, and reduce the risk of coronary vascular diseases
