Visceral fat and coronary pathology in male adolescents

Kortelainen, M-L, Särkioja, T·2001·International Journal of Obesity

Abstract

Objective To find out whether coronary atherosclerotic lesions and their precursors in male adolescents are associated with the amount of mesenteric and omental fat.Subjects A series of 40 forensic autopsy cases of ante-mortem healthy boys of 13-19 y of age were investigated.Methods Body height and weight, waist and hip circumferences and the thickness of the abdominal subcutaneous fat were measured, the body mass index (BMI) and waist-to-hip ratio (WHR) were calculated, and omental and mesenteric fat deposits were weighed. The intimal surface of the coronary arteries covered by lesions was measured by planimetry, and the thickness of the intima was measured by computerized image analysis. Intimal macrophage foam cells and smooth muscle cells were detected by immunohistochemisty, and macrophages were quantified.Results The intima thickness of the left anterior descending artery (LAD) and in the thickest lesion varied significantly across the tertiles of visceral fat when adjusted for age, being highest when the sum weight of omental and mesenteric fat exceeded 358 g. The intima thickness of the circumflex artery (CX) varied significantly across the tertiles of waist circumference when adjusted for age. No statistically significant associations with other indicators of obesity were found. Macrophage foam cells were present in the lesions and their maximal density/mm(2) correlated significantly with intima thickness in the LAD and CX. The maximal density of macrophages in CX and the right coronary artery (RCA) and in the thickest lesion varied significantly across the tertiles of visceral fat when adjusted for age, being highest when the amount of fat exceeded 358 g. The macrophage density also varied significantly across the tertiles of waist circumference in all vessels.Conclusions The results indicate that early macrophage-rich coronary lesions are associated with increased amounts of visceral fat in adolescent male individuals. This emphasizes the importance of effective prevention of weight gain in individuals with a tendency to accumulate visceral fat at an early age.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Central obesity is a risk marker, and probably a risk factor, for the development and progression of coronary artery disease.

    “Indeed, central obesity is undeniably a risk marker, and probably a risk factor for the development and progression of coronary artery disease (43, 105, 185–188, 229, 241, 328).”

  • Autopsy series have shown cardiac hypertrophy plus a variable extent of coronary artery disease in obese and nonobese subjects.

    “However, autopsy series present the opportunity to study heart tissue from obese and nonobese subjects, and in general, these studies have shown cardiac hypertrophy plus a variable extent of coronary artery disease (9, 64, 91, 147, 185–188, 300).”

    From Cardiac remodeling in obesity (2008) · cites this paper as [188]

  • Obesity, especially abdominal obesity, is a well-defined risk factor for the development of atherosclerotic coronary artery disease.

    “Suffice it to say that obesity, especially abdominal obesity, is a well-defined risk factor for the development of atherosclerotic coronary artery disease (12, 188, 241).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
