Abstract

Although the metabolic syndrome is associated with incident cardiovascular disease, low-density lipoprotein (LDL) cholesterol is a well-known risk factor for coronary atherosclerosis. The aim of this study was to clarify the clinical markers for coronary plaque vulnerability in acute coronary syndrome (ACS) patients (men) without the metabolic syndrome. Consecutive Japanese men with ACS (n=264) underwent emergent coronary angiography and B-mode carotid ultrasonography. Common carotid intima-media thickening and vascular dilatation were considered to indicate carotid artery remodeling. Patients were divided into two groups based on the number of complex plaques identified by coronary angiography. Abdominal obesity and low high-density lipoprotein cholesterol levels were frequently observed in overall patients with multiple complex coronary lesions. Although the metabolic syndrome was a significant independent predictor of multiple complex coronary lesions in overall ACS patients, a high LDL cholesterol level was an independent predictor in ACS patients without the metabolic syndrome. Carotid artery remodeling was an independent predictor of multiple complex coronary lesions in both overall patients and patients without the metab...Continue Reading

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
