When exercising, you’re not just increasing your heart rate. The blood vessels throughout your body also dilate to allow better blood flow to your heart muscles and other organs

Using cocaine and amphetamines, even though your heart is beating fast, the drugs causes arteries to constrict, restricting blood flows. So your heart is made to work harder without good blood flow. On top of that, the blood pressure exerted in your brain is vastly increased which can lead to a stroke.
