The hormonal regulation and enzymatic basis of endogenous lipolysis in heart are not yet completely elucidated. The lysosomal fraction from rat heart appeared to be markedly enriched in triglycerides and a significant reduction in triglycerides in this fraction was found after prolonged perfusion or
OBJECTIVE
The aim of the study was to examine the levels of adhesion molecules, high-sensitivity C-reactive protein (hs-CRP) and lipid spectrum of type 2 diabetic subjects with proven silent myocardial ischemia.
METHODS
We included in the study 19 patients with ischemia (Group 1) and 16 patients
Dietary n-3 fatty acids (FAs) may reduce cardiovascular disease risk. We questioned whether acute administration of n-3 rich triglyceride (TG) emulsions could preserve cardiac function and decrease injury after ischemia/reperfusion (I/R) insult. We used two different experimental models: in vivo,
Both increase and decrease of plasma triglycerides during acute coronary syndromes (ACS) are reported, however, a clinical relevance for these distinct metabolic responses is unclear. To test the association between distinct responses of lipid metabolism and cardiovascular risk, 39 subjects admitted
Triglyceride-rich lipoproteins are important in dietary lipid absorption and subsequent energy distribution in the body. Their importance in the gut-lymph may have been overlooked in sepsis, the most common cause of critical illness, and in gut ischemia-reperfusion injury, a common feature of many
Although strong evidence exists linking fasting plasma levels of LDL cholesterol (LDL-C) and HDL cholesterol (HDL-C) to risk for development of coronary artery disease (CAD), the data in support of an independent role for fasting triglyceride (TG) concentrations are weak. Humans are in the
High triglycerides (TG) and low high-density lipoprotein cholesterol (HDL-C) are important cardiovascular risk factors in women. The prognostic utility of the TG/HDL-C ratio, a marker for insulin resistance and small dense low-density lipoprotein particles, is unknown among high-risk
Triglyceride turnover in reperfused/ischemic rat hearts was investigated. Hearts were initially perfused under aerobic conditions for a 1-h "pulse" perfusion with 1.2 mM [1-14C]palmitate to label the endogenous lipid pools, followed by a 30-min period of no-flow ischemia or a 10-min period of
We studied lipolysis in the isolated rat heart, measured as glycerol release during anoxia, low-flow ischemia and subsequent reperfusion. It was found that the rate of lipolysis was enhanced during ischemia/anoxia while the lipase activities in tissue extracts involved in the myocardial lipolysis
The effect of coronary artery occlusion on endogenous triglycerides of left ventricular subepicardium and subendocardium was studied in the open-chest anaesthetised dog. Under control conditions, the subepicardium was found to have a greater concentration of triglycerides than the subendocardium.
The microsomal triglyceride transport protein (MTTP) is critical for assembly and secretion of apolipoprotein B (apoB)-containing lipoproteins and is most abundant in the liver and intestine. Surprisingly, MTTP is also expressed in the heart. Here we tested the functional relevance of OBJECTIVE
To examine the impact of physical fitness (PF) on the association between fasting serum triglycerides (FTG) and diabetes risk and whether temporal changes in FTG predict diabetes risk in healthy middle-aged men.
METHODS
FTG and PF (bicycle exercise test) were measured in 1962 men aged
