<qa>  What is the second reason why high blood sugar might be bad for heart attacks patients?We want to figure out why high blood sugar is bad for patients with heart attacks. Past research tells us there might be two reasons. The first is that high blood sugar increases inflammation which is part of the bodys natural response to heart attack. Inflammation is what causes a persons skin to turn hot and red after it is injured. Although inflammation is part of the bodys natural healing process, too much inflammation can be harmful. We think that patients with high blood sugar during heart attacks have too much inflammation. The second reason why high blood sugar might be bad for heart attack patients is that high blood sugar makes blood thicker. When a blood vessel is blocked, thick blood makes it harder for the heart to get the blood flow it needs. This is why doctors use aspirin and other blood thinners when they treat patients with heart attacks.
