Doctors monitor the amount of low-density lipoprotein (ldl) and high-density lipoprotein (hdl) in order to evaluate a patient’s overall health condition this allows doctors to verify if a patient is prone to develop heart diseases. Low-density lipoprotein (ldl) is the “bad,” unhealthy kind of cholesterol ldl cholesterol can build up in your arteries and form fatty, waxy deposits called plaques. Results the level of low-density lipoprotein (ldl) cholesterol was significantly lower in women with gestational diabetes than in those with normal glucose tolerance, but the triglyceride and high-density lipoprotein (hdl) cholesterol levels of the two groups were similar. A high triglyceride level combined with high ldl (bad) cholesterol or low hdl (good) cholesterol is linked with fatty buildups within the artery walls, which increases the risk of heart attack and stroke. Ldl cholesterol is called “bad” cholesterol, because elevated levels of ldl cholesterol are associated with an increased risk of coronary heart disease ldl lipoprotein deposits cholesterol on the artery walls, causing the formation of a hard, thick substance called cholesterol plaque.
Hdl has been labeled good cholesterol because it helps remove damaged ldl cholesterol from your arteries and has generally been associated with having less cardiovascular disease. High-density lipoprotein (hdl) is positively associated with a decreased risk of coronary heart disease (chd) as defined by the us national cholesterol education program adult treatment panel iii guidelines, an hdl cholesterol level (hdl-c) of 60 mg/dl or greater is a negative (protective) risk. Metabolic syndrome is the name for a group of risk factors that raises your risk for heart disease and other health problems, such as diabetes and stroke the term metabolic refers to the biochemical processes involved in the body's normal functioning. Because of the high cost of directly measuring hdl and ldl protein particles, blood tests are commonly performed for the surrogate value, hdl-c, ie the cholesterol associated with apoa-1/hdl particles.
The framingham heart study began in 1948 and helped discover that bad low-density lipoprotein (ldl) and good high-density lipoprotein (hdl) cholesterol levels can help predict the risk of cardiovascular diseases such as heart attack and stroke. Reason for the study it has been known that high ldl cholesterol and low hdl cholesterol levels increase heart attack risk in older individuals. 1 departments of medicine and community health sciences, faculty of medicine, university of calgary, calgary, ab, canada, t2n 4n1 2 department of ambulatory care and community medicine, university of lausanne, lausanne, ch1011, switzerland briel and colleagues demonstrate this phenomenon for hdl. The authors found that low hdl cholesterol levels were associated with a number of factors that affect health, including low incomes, unhealthy lifestyles, higher triglycerides levels, other cardiac risk factors, and medical problems.
Hdl cholesterol (high density lipoprotein), on the other hand, is the good form hdl travels around in your bloodstream, picking up excess ldl cholesterol and bringing it back to your liver to be reprocessed. Health benefits of hdl cholesterol: hdl reduces the build up of cholesterol in the blood vessels, hence helps prevent artherosclerosis and its complications hdl reduces the risk of heart diseases. But a high level of 'good' (hdl) cholesterol can help keep that 'bad' (non-hdl) cholesterol in check there is no specific target cholesterol level because your doctor is looking at your overall risk of developing heart and circulatory disease including whether you smoke or have high blood pressure.
Ldl = tc - hdl - 02 tg the values you need to insert in the equation are measurements from the standard cholesterol - focused blood test, called the lipid panel: tc - total cholesterol - it's the sum of the concentration of all cholesterol particles, both the perceived good and bad ones. Total cholesterol/hdl cholesterol and ldl/hdl cholesterol ratios the total/high-density lipoprotein (hdl) cholesterol ratio, known as the atherogenic or castelli index and the ldl/hdl cholesterol ratio are two important components and indicators of vascular risk, the predictive value of which is greater than the isolated parameters. Background obesity and low high-density lipoprotein-cholesterol (hdl-c) levels are associated with cardiovascular risk surprisingly, despite a greater prevalence of obesity and lower hdl concentrations than white women, black south african women are relatively protected against ischaemic heart disease. Results from the framingham heart study offspring cohort, where 3590 individuals without known cardiovascular disease were studied from 1987 to 2011, found that cardiovascular risk was not only associated with high-density lipoprotein cholesterol but also was associated with a combination hdl levels and levels of low-density lipoprotein.
Ldl deficiency is a greater health risk than high ldl ldl has been labeled (inappropriately) as the “bad” cholesterol cancer incidence is also higher in women with low total cholesterol and low hdl low total cholesterol and low ldl along with low vldl and triglycerides are associated, not with breast cancer, but with benign breast. High tg and low hdl level was associated with chd risk in participants with an ldl-c level of ≥130 mg/dl, but this was not observed in those participants with lower ldl-c levels sex did not appear to modify these associations.

Hdl is considered the good cholesterol because higher levels are associated with decreased risk for heart disease serum blood cholesterol test a physician will have a patient undergo a serum blood cholesterol test so that the differing levels of the various types of cholesterol may be measured.
