Study shows value of calcium scan in predicting heart attack, stroke among those considered at risk
A new study shows that coronary artery calcium (CAC) screening, an assessment tool that is not currently recommended for people considered at low risk, should play a more prominent role in helping determine a person's risk for heart attack and heart disease-related death, as well as the need for angioplasty or bypass surgery. CAC screening provides a direct measure of calcium deposits in heart arteries and is easily obtained on a computed tomography (CT) scan."We showed that by using only the traditional risk factors, we miss a significant percentage of individuals at high risk.

What Causes Muscle Weakness?
Discussion Muscle tone is the slight tension that is felt in a muscle when it is voluntarily relaxed. It can be assessed by asking the patient to relax and then taking the muscles through a range of motion such as moving the wrists, forearm and upper arm. Muscle strength is the muscle’s force against active resistance. Impaired strength is called weakness or paresis. There are 5 levels of muscle strength. 0 = No muscle contraction detected 1 = Barely detected flicker of contraction 2 = Active movement with gravity eliminated 3 = Active movement against gravity 4 = Active movement against gravity and some resistance ...

Density of CAC Has Role in Heart Risk (CME/CE)
(MedPage Today) -- The density of calcium in coronary artery plaque is inversely and significantly associated with heart disease and stroke risk independent of calcium volume and should be considered whenever calcium scanning is used to assess patient risk, researchers reported.

“De-Risking” Risk Reduction: Should Coronary Artery Calcium Scoring Be the Gatekeeper to Preventive Pharmacotherapy With the Polypill?∗
The cardiovascular disease (CVD) epidemic remains the leading cause of death worldwide . Widespread adoption of the Western diet and lifestyle by populations in emergent countries with low or middle income has resulted in dramatic increases in the incidence of coronary heart disease and stroke. An overwhelming proportion of the cardiovascular risk is explained by the cumulative presence of classic and potentially modifiable risk factors, and this effect does not seem to be influenced by sex, ethnicity, or geography . Therefore, to effectively reduce risk and improve outcomes, prevention strategies should be conducted and i...

Saturated fat link with heart disease questioned
This article is one doctor's opinion based on his own knowledge, research and experience. However, it is fair to say there is an ongoing debate about how far cholesterol is a risk factor for heart disease, especially in people who are otherwise healthy. There is also a similar debate about the use of statins in people who have no evidence of cardiovascular disease. This is alongside ongoing research into the components of LDL and the different types of lipoproteins known to increase risk the most. None of this relevant new evidence is covered by the news reporting.   What should you eat? There is no need to change curren...

Effect of lower sodium intake on health: systematic review and meta-analyses
This is another article that supports the literature for reduction in salt intake for overall population health. This systematic further shows that not only does salt lower blood pressure, but there are no adverse effects on lipids, catecholamine levels of renal function. Furthermore, it is associated with lower risk of stroke and fatal coronary heart disease in adults. : Effect of increased potassium intake on cardiovascular risk factors and disease: systematic review and meta-analyses Benefits and harms of erythropoiesis-stimulating agents for anemia related to cancer: a meta-analysis.

Opposite impacts of dietary versus supplemental calcium on cardiovascular health
Commentary on: Li K, Kaaks R, Linseisen J, et al.. Associations of dietary calcium intake and calcium supplementation with myocardial infarction and stroke risk and overall cardiovascular mortality in the Heidelberg cohort of the European prospective investigation into cancer and nutrition study (EPIC-Heidelberg). Heart 2012;98:920–5. Context Calcium supplementation is widely used to maintain bone health. Growing data suggests that calcium supplementation, but not dietary calcium intake, may harm cardiovascular (CV) health.1 2 There is no randomised controlled trial (RCT) that addressed CV events as primary endpoints...

Fish in the diet: A review
Summary Fish plays a useful role in a healthy and balanced diet, and its consumption has long been associated with several health benefits. Fish provides a variety of nutrients, including protein and long‐chain omega‐3 polyunsaturated fatty acids (n‐3 PUFAs), as well as micronutrients including selenium, iodine, potassium, vitamin D and B‐vitamins. Intakes of some of these micronutrients, including iodine and vitamin D, are low in some population groups in the UK, which makes fish a valuable contributor to intakes of these. The long‐chain n‐3 PUFA eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), pres...

Mortality and Morbidity During and After Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial: Results by Sex Clinical Trial - ALLHAT
To determine whether an angiotensin-converting enzyme inhibitor (lisinopril) or calcium channel blocker (amlodipine) is superior to a diuretic (chlorthalidone) in reducing cardiovascular disease incidence in sex subgroups, we carried out a prespecified subgroup analysis of 15 638 women and 17 719 men in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). Total follow-up (active treatment + passive surveillance using national administrative databases to ascertain deaths and hospitalizations) was 8 to 13 years. The primary outcome was fatal coronary heart disease or nonfatal myocardial i...

Cohort study: Long term calcium intake and rates of all cause and cardiovascular mortality
Source: BMJ Area: News Supplementation with calcium has become increasingly common but recent analyses of trials have suggested a higher risk of both ischemic heart disease and stroke with calcium supplements in women. To investigate the association between long term dietary and supplemental intake of calcium with all cause mortality as well as with cardiovascular mortality, researchers conducted a prospective longitudinal cohort study in Swedish women.   The Swedish mammography cohort, established in 1987-90, provided the data for the purposes of this study. Women were born between 1914 and 1948 and followed-up ...

Researchers Find Gene Variant Linked To Aortic Valve Disease
NIH-funded consortium finds connection between lipoprotein(a) and valve calcification � A newly identified genetic variant doubles the risk of calcium buildup in the heart's aortic valve. Calcium buildup is the most common cause of aortic stenosis, a narrowing of the aortic valve that can lead to heart failure, stroke, and sudden cardiac death. � An international genomics team called CHARGE (Cohorts for Heart and Aging Research in Genomic Epidemiology) found the variant in the gene for lipoprotein(a), a cholesterol-rich particle that circulates in the blood...

Any defence of sugar is pure confection | Aseem Malhotra
More and more people are challenging the food industry's PR machine. The evidence shows that sugar, not fat, is the enemyThe public health minister, Anna Soubry, has commented that the poor are more likely to be obese. It is well known that social status is linked to health, but her comments were also motivated by a mentality that victimises the most vulnerable. She should really be directing her criticism at the food industry. There is no doubt that an oversupply of cheap junk food fuelled by unregulated and irresponsible marketing limits our ability to make healthy choices. But there is an equally important question that...
