Why is obesity a risk factor for CVD?

Obesity increases the risk for CHD, by increasing the load of the atherosclerotic plaques, characterized by greater macrophage infiltration and plaque instability. The chronic low-grade systemic pro-inflammatory status in patients with obesity seems to be responsible, at least in part, for the increased CHD risk.

What is a normal heart rate for an obese person?

We categorized all participants into four subgroups: normal weight with heart rate <80 bpm, overweight with heart rate <80 bpm, normal weight with heart rate ≥80 bpm and overweight with heart rate ≥80 bpm.
