Sedentary Life Style

In different epidemiological studies, an association between sedentary life style and incidence of cardiovascular diseases has been demonstrated. Dyslipidaemia is one of the important risk factors of cardiovascular disease. An association of dyslipidaemia with sedentary life style has been considered. This study was carried out among 50 sedentary workers (teachers, office staffs, bank employees) at Pabna District and 50 individuals with non-sedentary jobs matched for age group and sex for the control group to see the association. Body mass index (BMI), blood pressure (BP), plasma level of glucose, total cholesterol, low density lipoprotein (LDL), and triglycerides (Tgs) were found to be significantly higher whereas high density lipoprotein (HDL) was found to be significantly lower among the sedentary workers as compared with the control subjects. From the study, it appears that dyslipidaemia is more common in sedentary workers and the relative risk for cardiovascular disease is increased among them due to the sedentary nature of their jobs.

Lipid metabolism has gained cardiological interest only after statins were demonstrated to reduce cardiovascular disease in secondary and primary prevention. Therefore, this chapter first introduces the physiological and atherogenic properties of lipoproteins, before focusing on interventions. Both the efficacy and safety of statins have been proven in numerous randomized clinical trials. Because there is a considerable residual risk in statin-treated patients, additional approaches have been investigated. The focus is now on further reductions in low-density lipoprotein (LDL) cholesterol levels. First, high-intensity statin regimens were shown to reduce residual risk. Subsequently, ezetimibe was demonstrated, for the first time, to have a beneficial effect as a non-statin lipid intervention. More recently, inhibitors of the enzyme PCSK9 have demonstrated a very high efficacy in reducing LDL cholesterol levels. Although the causality of LDL for atherosclerotic cardiovascular disease has been proven in epidemiological studies, including Mendelian randomization studies, as well as interventional trials, adherence to statins and other therapies is far from optimal. In contrast, interventions to increase high-density lipoprotein (HDL) cholesterol levels could not proven to have further benefits when combined with statins.

New Guidelines

A consensus has formed based on epidemiological studies and clinical trials that intervention to reduce low density lipoprotein cholesterol (LDL-C) will reduce cardiovascular disease (CVD) events. This has progressively reduced the thresholds for intervention and targets for treatment. Whist statins are sufficient for many people in primary prevention, they only partially achieve the newer targets of secondary prevention for established CVD. Increasing use of statins has highlighted that 1–2% cannot tolerate these drugs. Other cholesterol-lowering drugs such as ezetimibe add to the benefits of statins but have limited efficacy. The discovery of activating mutations in proprotein convertase subtilisin kexin-9 (PCSK9) as a cause of familial hypercholesterolaemia while inactivating mutations lower LDL-C led to the idea to develop PCSK9 inhibitors as drugs. This article reviews the history of lipid-lowering therapies, the discovery of PCSK9 and the development of PCSK9 inhibitors. It reviews the key trials of the current antibody-based drugs and how these have influenced new guidelines. It also reviews the controversy caused by their cost and the increasing application of health economics to determine the optimum strategy for implementation of novel therapeutic pathways and surveys other options for targeting PCSK9 as well as other LDL-C lowering compounds in late development.

Abstract: Introduction:  Globally it is documented that CVD has multi-factorial aetiology and many factors like increased BMI, hypertension (HTN), stress and diabetes determine the risk of CVD. The prevalence of risk factors for cardio vascular disease (CVD) is on increase in the developing nations of the world. Objectives: The purpose of the study was   to find out the prevalence of cardiovascular disease and its risk factors among employees of Sindh Government in Karachi, Pakistan.Method: It was hospital based cross sectional study. A total of 150 subjects (govt employees of Sindh Government) were interviewed by using consecutive sampling technique. Data on serum cholesterol, BMI, blood pressure, history of hypertension, diabetes and cardiovascular diseases was collected, in addition to demographic data. Results: Out of 150 subjects interviewed, 20.6% reported to have CVD. The most prevalent risk factor was hypertension, found in 58% respondents. Other risk factors were diabetes (45%), sedentary life style (50%), obesity (28%), dyslipidaemia (30%), smoking (20%), positive family history (26%). In 6% of subjects, three major risk factors were present. The risk factors, strongly associated with CVD in our study were diabetes (p<0.01), hypertension (p<0.001) and family history of CVD (p<0.02). There is strong association of increasing age on risk of developing CVD (p< 0.001). Conclusion: The results show that there is high frequency of CVD risk factors in employees of health department in Karachi. The high prevalence of risk factors, especially hypertension, sedentary life style, obesity and diabetes should be of great concern.

Objective: Patients with chronic renal failure have high burden of cardiovascular morbidity and mortality. This study was carried out to investigate the development of cardiovascular disease in chronic renal failure among female patients on dialysis treatment in Nigeria. Materials and Methods: A total of 40 adult female subjects participated in this study. 20 of them were apparently healthy and served as control group while the rest 20 were female patients with chronic renal failure (CRF) on dialysis treatment. Fasting blood samples were collected and their lipid profile, Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein –Cholesterol (HDL-C), Low Density Lipoprotein –Cholesterol (LDL-C), and Very Low Density Lipoprotein –Cholesterol (VLDL-C) were estimated using enzymatic methods. The percentages of these parameters in circulation were obtained. The cardiovascular risk ratios (TC/HDL-C and LDL-C/HDL-C) were calculated. Result: The lipid profile of the chronic renal failure patients (TC 5.70±0.80mmol/l, TG 1.46±0.40mmol/l, LDL-C 3.50±0.2mmol/l, and VLDL-C 0.67±0.2mmol/l) were significantly higher (p<0.05) than that of control group (TC 4.03±0.13mmol/l, TG 1.10± 0.3mmol/l , LDL-C 1.85±0.5mmol/l, and VLDL-C 0.50± 0.01mmol/l) except HDL-C. HDL-C of the CRF patients (1.40±0.2mmol/l) was significantly lower (p<0.05) than that of healthy women (HDL-C 1.70± 0.04mmol/l). These depict no difference in the percentage of VLDL-C & TG in circulation between the control (VLDL –C 5% and TG 45%) and chronic renal failure patients (VLDL –C 5% and TG 44%). In CRF group, it was observed that 28% of the total plasma lipid (12.73mmol/l) was LDL-C but in healthy women, percentage of LDL-C in circulation (out of 9.18mmol/l) was 20%. It was also observed that 11% of the total plasma lipid (12.73mmol/l) in CRF patients was HDL-C but in healthy subjects, the percentage of HDL-C in circulation (out of 9.18mmol/l) was 19%. The cardiovascular risk indices (TC/HDL-C and LDL-C/HDL-C) of the CRF patients (TC/HDL-C 3.91±0.24 and LDL-C/HDL-C 2.50±0.01) were significantly higher (p<0.05) than those of the healthy subjects (TC/HDL-C 2.40±0.09, LDL-C/HDL-C 1.10±0.08). Conclusion: These results indicate that chronic renal failure is a risk factor to development of cardiovascular disease in female patients on dialysis.DOI: http://dx.doi.org/10.3329/jom.v16i1.22382 J MEDICINE 2015; 16 : 14-17

Цель - исследование взаимосвязи факторов риска сердечно-сосудистых заболеваний и развития предгипертонии. Методика. Проведен сравнительный и корреляционный анализы показателей модифицируемых и немодифицируемых факторов риска сердечно-сосудистых заболеваний у обследованных лиц в возрасте 30-60 лет с «оптимальным» артериальным давлением, (n = 63, АД <120/80 мм рт.ст.) и лиц с предгипертонией (n = 52, АД = 120-139/80-89 мм рт.ст.). Результаты. Показано, что лица с предгипертонией по сравнению с группой лиц, имеющих «оптимальное» артериальное давление характеризуются статистически значимо повышенным содержанием холестерина и холестерина липопротеидов низкой плотности, интеллектуальным характером трудовой деятельности, а также значимыми сочетаниями факторов риска: повышенный уровень холестерина липопротеидов низкой плотности с интеллектуальным характером трудовой деятельности; повышенное содержание креатинина с уровнем триглициридов; наследственная отягощенность по заболеваниям почек и интеллектуальным характером трудовой деятельности; наследственная отягощенность по сахарному диабету и гипертрофия левого желудочка сердца. У лиц с предгипертонией документированы перестройки структуры взаимосвязи (количество, направленность и сила корреляций) между показателями факторов риска в сравнении с лицами, имеющими «оптимальное» артериальное давление. Заключение. Выявленные особенности взаимосвязей факторов риска сердечно-сосудистых заболеваний при предгипертонии рассматриваются как проявление начальной стадии дизрегуляционной патологии и нарушения регуляции физиологических систем поддержания оптимального уровня артериального давления. The aim of the study was to investigate the relationship between risk factors for cardiovascular disease and development of prehypertension. Methods. Comparative and correlation analyses of modifiable and non-modifiable risk factors for cardiovascular disease were performed in subjects aged 30-60 with «optimal» blood pressure (n = 63, BP <120/80 mm Hg) and prehypertension (n = 52, BP = 120-139 / 80-89 mm Hg). Results. The group with prehypertension compared with the «optimal» blood pressure group had significantly increased serum levels of low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol, sedentary/intellectual type of occupation, and significant combinations of risk factors. The risk factor combinations included an increased level of LDL cholesterol and a sedentary/intellectual occupation; increased serum levels of creatinine and triglycerides; hereditary burden of kidney disease and a sedentary/intellectual occupation; hereditary burden of diabetes mellitus and cardiac left ventricular hypotrophy. In subjects with prehypertension compared to subjects with «optimal» blood pressure, changes in correlations (correlation number, direction, and strength) between parameters of risk factors were documented. Conclusion. The features of interrelationships between risk factors for cardiovascular disease observed in prehypertension are considered a manifestation of early dysregulation pathology and disordered regulation of physiological systems, which maintain optimal blood pressure.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.
