Studies Of Genes Have Shown An Link Between The Level Of Blood Fat And Heart Disease.
Scientists have want debated the position triglyceride levels might monkey business in heart disease, and finally they have genetic evidence linking on a trip concentrations of the blood fat to an increased risk of heart trouble masolin. Until now, cholesterol levels were the explanation targets of heart disease prevention efforts, but experts as a new report in the May 8 issue of The Lancet may revise that thinking.

Triglycerides, a greater source of human energy, are produced by the liver or derived from foods. "Despite several decades of research, it has remained unsystematic whether raised levels of triglyceride can cause heart disease," said lead researcher Nadeem Sarwar, a lecturer in cardiovascular epidemiology at the University of Cambridge in England does orange juice increase your sperm count. "We found that multitude with a genetically programmed disposition for higher triglyceride levels also had a greater risk of heart disease".

So "This suggests that triglyceride pathways may be labyrinthine in the development of heart disease". To traverse a genetic link between triglycerides and heart disease, Sarwar's team collected data on 302430 tribe who participated in 101 studies. "We employed novel genetic approaches - self-styled 'Mendelian randomization analysis,'" he said.

Specifically, the researchers looked at mutations in the apolipoprotein A5 gene, a known determinant of triglyceride concentrations. They found that for every copy of the variant, there was a 16 percent multiply in triglyceride concentrations, so two copies increased triglyceride levels 32 percent. People with two such variants had a 40 percent increased imperil of developing insensitivity disease, the researchers calculated.

Although these genetic findings call a causative role for triglyceride pathways in the development of middle disease, they do not replace the need for large randomized clinical trials of medications that lower blood triglyceride levels. uch trials should inform establish whether reducing triglyceride concentration can tone down the risk of heart disease. "There are several medications currently available or under development that can influence blood triglyceride levels". Drug maker Novartis, the British Heart Foundation and the UK Medical Research Council funded the study.

Dr Gregg C Fonarow, a professor of cardiovascular medicament and chief of the Ahmanson-UCLA Cardiomyopathy Center at the University of California, Los Angeles, also said more explore is needed. "Elevated LDL cholesterol has been definitively established as a noteworthy modifiable cardiovascular jeopardize factor. There is also strong evidence that low levels of HDL identify individuals at increased peril for cardiovascular events. However, the independent role that elevated triglyceride levels freedom in cardiovascular risk has been more difficult to establish and controversial".

This study suggests a modest independent alliance between triglycerides and coronary heart disease. "Despite these findings it still remains to be demonstrated whether lowering triglyceride levels in patients with - or at jeopardy for - cardiovascular disease will in and of itself reduce the risk of cardiovascular events and if so by how much".

Another expert, Dr Byron Lee, an helper professor of cardiology at the University of California, San Francisco, suggested the scrutiny could alter the guidelines for heart prevention. "Traditionally, clinicians have focused only on getting our patients' LDL down and our HDL up because we plan that these were the major players in heart disease hair statnar kis compani or kis size ka achcha hota hy. However, this office indicates that we need to now worry about high triglyceride levels as well".
