Atherosclerosis

Overview

Atherosclerosis is a condition where the arteries become narrowed and hardened due to a buildup of plaque. This can lead to cardiovascular complications in pets, primarily affecting dogs and cats.

Causes

In dogs, atherosclerosis usually develops secondary to conditions that raise blood lipids, particularly hypothyroidism and diabetes mellitus. These raise cholesterol and triglyceride levels, which drive plaque buildup in the arteries. A breed predisposition to hyperlipidemia, such as in Miniature Schnauzers, can also contribute.
