The maximum heart rate. I thought it would be something fancy, but it's not.

Yes, exhaustion can contribute to a heart attack, particularly when it leads to increased stress and strain on the heart. Chronic fatigue can elevate blood pressure and stress hormone levels, which may trigger heart-related issues. Additionally, physical exhaustion during intense activity can strain the heart, especially in individuals with pre-existing conditions. It's essential to manage stress and ensure adequate rest to maintain cardiovascular health.

The blood in the pulmonary veins contains the highest concentration of oxygen since it has just been oxygenated in the lungs before returning to the heart to be pumped to the rest of the body.

Heart failure. In some cases, the horse's heart literaly explodes and the horse will drop dead under the rider. Less likely, extreme exhaustion.
A four chambered heart is a closed system and ensures that all blood passing through it is oxygenated. A three chambered heart has both oxygenated an non-oxygenated blood mixed in the single ventricle therefore the blood is only half oxygenated. A three chambered creature would suffer from exhaustion long before a four chambered creature.
