Dyslipidemia

Diabetes and inflammation influence the development of atherosclerosis. We performed a study that showed the inflammatory markers high-sensitivity C-reactive protein and lipoprotein-associated phospholipase A2 were lowered with the use of fenofibrate, simvastatin, and combination therapy. The anti-inflammatory effects were most pronounced among patients with elevated baseline inflammatory markers. Combination therapy significantly altered lipid concentrations and exerted a greater positive effect on low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides than monotherapy with either drug.

The use of statins to treat hyperlipidemia is well established.

Multislice computed tomography (MSCT) detects proximal coronary atherosclerotic plaque or obstructive coronary artery disease (CAD) in "a significant proportion" of patients with a low or intermediate Framingham risk score, according to research conducted at the Cleveland Clinic in Ohio.

We evaluated the prognostic value of cardiac magnetic resonance (CMR) stress testing with direct comparison of adenosine stress first-pass perfusion and dobutamine stress wall motion imaging among 513 subjects with known or suspected coronary heart disease over a median follow-up period of 2.3 years. Positive results on CMR stress testing identified subjects at high risk for subsequent cardiac events (nonfatal myocardial infarction or cardiac death), whereas normal CMR stress test results were associated with a very low annual cardiac event rate.

Despite the fact that prehypertension has been shown to be associated with atherosclerosis and target-organ damage, no studies evaluating coronary flow reserve (CFR) among prehypertensive patients have been done. We assessed CFR in normotensive subjects, in subjects with prehypertension, and in newly diagnosed and never-treated subjects with established hypertension. We found that CFR was decreased in prehypertensive subjects, although not as significantly as in subjects with hypertension.

Ever since the observation in the 1950s that high-density lipoprotein (HDL) cholesterol was inversely correlated with coronary artery disease, there have been confounding data that have not been reconciled.

As outlined by the authors, use of metformin is an appealing option because it is safe, produces few side effects, and is a cost-effective way to target some of the defects known to contribute to the metabolic defects associated with diabetes.

The well-established causative role of low-density lipoprotein particles in atherosclerotic plaque development has led to this biomarker being a primary target of treatment in the prevention of coronary artery disease.

Cardiovascular disease (CVD), which includes coronary artery disease (CAD), hypertension, stroke, and other CVDs, continues to be the leading cause of mortality among both men and women. For women, however, increasing awareness and understanding of how CVD affects them remains a challenge.

There is some debate about whether the risk of cardiovascular events associated with low high-density lipoprotein (HDL) cholesterol levels is attenuated by very low low-density lipoprotein (LDL) cholesterol levels (< 60 mg/dL), which can be obtained with statins and combination therapy.

A recent meta-analysis of 31 randomized controlled trials with 4500 participants showed that metformin treatment significantly decreased weight, improved dyslipidemia and insulin resistance, and reduced the incidence of new-onset diabetes by 40%, with beneficial effects maintained over time. Further studies will show whether the metabolic improvements achieved with metformin treatment will ultimately result in a decrease in cardiovascular morbidity and mortality.

Tim Russert's sudden death last week at 58 from a heart attack was another statistic in that he was being treated for CAD and his doctors "did not realize how severe the disease was."
